We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'. Add to this or # override it after sourcing this library to reflect the full set of # options your script accepts. usage_message="\ --debug enable verbose shell tracing -W, --warnings=CATEGORY report the warnings falling in CATEGORY [all] -v, --verbose verbosely report processing --version print version information and exit -h, --help print short or long help message and exit " # Additional text appended to 'usage_message' in response to '--help'. long_help_message=" Warning categories include: 'all' show all warnings 'none' turn off all the warnings 'error' warnings are treated as fatal errors" # Help message printed before fatal option parsing errors. fatal_help="Try '\$progname --help' for more information." ## ------------------------- ## ## Hook function management. ## ## ------------------------- ## # This section contains functions for adding, removing, and running hooks # to the main code.

The names of cairo-make-scale-matrix and cairo-make-rotate-matrix have been fixed to cairo-matrix-scale and cairo-matrix-rotate, following the original C names. The following new functions have been added: cairo-destroy, cairo-surface-destroy, cairo-image-surface-create-for-data, cairo-image-surface-get-data, and cairo-image-surface-set-data. guile-cairo 1.9.91 -- 2011-11-22 ================================ * Moved to a new home on Savannah: http://www.non-gnu.org/guile-cairo/. The git repository is now properly hosted there, instead of on my http server; see http://www.non-gnu.org/guile-cairo/dev/ for details. guile-cairo 1.9.90 -- 2011-04-23 ================================ * Updated with support for Cairo 1.6, 1.8, and 1.10. Documentation was updated as well. This is a prerelease to shake out problems with the API. guile-cairo 1.4.1 -- 2011-04-22 =============================== * Guile-Cairo has moved to git. See the HACKING file for information on how to access Guile-Cairo. * Guile-Cairo's license has been upgraded to the LGPL version 3 or later. This should not cause problems for any users. See http://www.gnu.org/licenses/gpl-faq.html#AllCompatibility for more information. guile-cairo 1.4.0 -- 2007-07-28 =============================== * Guile-Cairo, like Cairo itself, now has a stable API and ABI. There will be no more incompatible changes made. * Users may now contribute improvements to the generated documentation. See doc/README for more information. * Some Scheme name typos fixed, after looking over the exported symbol list: cairo-image-surface-get-height, cairo-image-surface-get-stride, cairo-path-data-type-get-values. guile-cairo 1.3.93 - 2007-07-17 =============================== * Guile-Cairo is now documented. Documentation is available in PDF, HTML, Info, and online within Guile via the help system. guile-cairo 1.3.92 - 2007-06-12 =============================== * File output and input functions can now read from and write to Scheme ports. The convention is that the filename is an optional last argument, and that if it is not given, output will be written to the current output port, and likewise for input and the current input port. For example: (with-output-to-file "/tmp/guile-cairo.png" (lambda () (cairo-surface-write-to-png surf))) guile-cairo 1.3.91 -- 2007-06-08 ================================ * Add backwards compatability to Cairo 1.2. Thanks to Steve Tell. * Build fix for external projects using guile-cairo: header files now include everything they depend on. * Bugfixes in vector type accessors and cairo-set-source-rgba. guile-cairo 1.3.90 -- 2007-05-18 ================================ * Initial release.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH. The drawback is that using absolute paths prevent a # configured tree to be moved without reconfiguration.

The current point is returned in the user-space coordinate system. If there is no defined current point or if @var{cr} is in an error status, @var{x} and @var{y} will both be set to 0.0. It is possible to check this in advance with @code{cairo-has-current-point}. Most path construction functions alter the current point. See the following for details on how they affect the current point: @code{cairo-new-path}, @code{cairo-new-sub-path}, @code{cairo-append-path}, @code{cairo-close-path}, @code{cairo-move-to}, @code{cairo-line-to}, @code{cairo-curve-to}, @code{cairo-rel-move-to}, @code{cairo-rel-line-to}, @code{cairo-rel-curve-to}, @code{cairo-arc}, @code{cairo-arc-negative}, @code{cairo-rectangle}, @code{cairo-text-path}, @code{cairo-glyph-path}, @code{cairo-stroke-to-path}. Some functions use and alter the current point but do not otherwise change current path: @code{cairo-show-text}. Some functions unset the current path and as a result, current point: @code{cairo-fill}, @code{cairo-stroke}. @table @var @item cr a cairo context @item x return value for X coordinate of the current point @item y return value for Y coordinate of the current point @end table @end deffn @deffn Function cairo-new-path (@var{cr}@tie{}@code{}) Clears the current path.

Note that the existing path is not affected. After this call there will be no current point. In many cases, this call is not needed since new sub-paths are frequently started with @code{cairo-move-to}. A call to @code{cairo-new-sub-path} is particularly useful when beginning a new sub-path with one of the @code{cairo-arc} calls. This makes things easier as it is no longer necessary to manually compute the arc's initial coordinates for a call to @code{cairo-move-to}. @table @var @item cr a cairo context @end table Since 1.2 @end deffn @deffn Function cairo-close-path (@var{cr}@tie{}@code{}) Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to @code{cairo-move-to}), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path. The behavior of @code{cairo-close-path} is distinct from simply calling @code{cairo-line-to} with the equivalent coordinate in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead, there is a line join connecting the final and initial segments of the sub-path. If there is no current point before the call to @code{cairo-close-path}, this function will have no effect. Note: As of cairo version 1.2.4 any call to @code{cairo-close-path} will place an explicit MOVE_TO element into the path immediately after the CLOSE_PATH element, (which can be seen in @code{cairo-copy-path} for example). This can simplify path processing in some cases as it may not be necessary to save the "last move_to point" during processing as the MOVE_TO immediately after the CLOSE_PATH will provide that point. @table @var @item cr a cairo context @end table @end deffn @deffn Function cairo-arc (@var{cr}@tie{}@code{}) (@var{xc}@tie{}@code{}) (@var{yc}@tie{}@code{}) (@var{radius}@tie{}@code{}) (@var{angle1}@tie{}@code{}) (@var{angle2}@tie{}@code{}) Adds a circular arc of the given @var{radius} to the current path. The arc is centered at (@var{xc}, @var{yc}), begins at @var{angle1} and proceeds in the direction of increasing angles to end at @var{angle2}. If @var{angle2} is less than @var{angle1} it will be progressively increased by 2*M_PI until it is greater than @var{angle1}. If there is a current point, an initial line segment will be added to the path to connect the current point to the beginning of the arc. If this initial line is undesired, it can be avoided by calling @code{cairo-new-sub-path} before calling @code{cairo-arc}. Angles are measured in radians. An angle of 0.0 is in the direction of the positive X axis (in user space). An angle of @samp{M_PI}/2.0 radians (90 degrees) is in the direction of the positive Y axis (in user space). Angles increase in the direction from the positive X axis toward the positive Y axis. So with the default transformation matrix, angles increase in a clockwise direction. (To convert from degrees to radians, use @samp{degrees * (M_PI / 180.)}.) This function gives the arc in the direction of increasing angles; see @code{cairo-arc-negative} to get the arc in the direction of decreasing angles. The arc is circular in user space. To achieve an elliptical arc, you can scale the current transformation matrix by different amounts in the X and Y directions. For example, to draw an ellipse in the box given by @var{x}, @var{y}, @var{width}, @var{height}: @example cairo_save (cr); cairo_translate (cr, x + width / 2., y + height / 2.); cairo_scale (cr, width / 2., height / 2.); cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI); cairo_restore (cr); @end example @table @var @item cr a cairo context @item xc X position of the center of the arc @item yc Y position of the center of the arc @item radius the radius of the arc @item angle1 the start angle, in radians @item angle2 the end angle, in radians @end table @end deffn @deffn Function cairo-arc-negative (@var{cr}@tie{}@code{}) (@var{xc}@tie{}@code{}) (@var{yc}@tie{}@code{}) (@var{radius}@tie{}@code{}) (@var{angle1}@tie{}@code{}) (@var{angle2}@tie{}@code{}) Adds a circular arc of the given @var{radius} to the current path.

In this scheme, we use even vs. odd numbers to distinguish fixed points in the software vs. in-progress development, (such as from git instead of a tar file, or as a "snapshot" tar file as opposed to a "release" tar file). @example _____ Major. Always 1, until we invent a new scheme. / ___ Minor. Even/Odd = Release/Snapshot (tar files) or Branch/Head (git) | / _ Micro. Even/Odd = Tar-file/git | | / 1.0.0 @end example Here are a few examples of versions that one might see. @example Releases -------- 1.0.0 - A major release 1.0.2 - A subsequent maintenance release 1.2.0 - Another major release Snapshots --------- 1.1.2 - A snapshot (working toward the 1.2.0 release) In-progress development (eg. from git) -------------------------------------- 1.0.1 - Development on a maintenance branch (toward 1.0.2 release) 1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release) @end example @section Compatibility The API/ABI compatibility guarantees for various versions are as follows. First, let's assume some cairo-using application code that is successfully using the API/ABI "from" one version of cairo. Then let's ask the question whether this same code can be moved "to" the API/ABI of another version of cairo. Moving from a release to any later version (release, snapshot, development) is always guaranteed to provide compatibility. Moving from a snapshot to any later version is not guaranteed to provide compatibility, since snapshots may introduce new API that ends up being removed before the next release. Moving from an in-development version (odd micro component) to any later version is not guaranteed to provide compatibility. In fact, there's not even a guarantee that the code will even continue to work with the same in-development version number. This is because these numbers don't correspond to any fixed state of the software, but rather the many states between snapshots and releases. @section Examining the version Cairo provides the ability to examine the version at either compile-time or run-time and in both a human-readable form as well as an encoded form suitable for direct comparison. Cairo also provides the macro @code{cairo-version-encode} to perform the encoding. @example Compile-time ------------ CAIRO_VERSION_STRING Human-readable CAIRO_VERSION Encoded, suitable for comparison Run-time -------- cairo_version_string() Human-readable cairo_version() Encoded, suitable for comparison @end example For example, checking that the cairo version is greater than or equal to 1.0.0 could be achieved at compile-time or run-time as follows: @example ##if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(1, 0, 0) printf ("Compiling with suitable cairo version: %s\n", %CAIRO_VERSION_STRING); ##endif if (cairo_version() >= CAIRO_VERSION_ENCODE(1, 0, 0)) printf ("Running with suitable cairo version: %s\n", cairo_version_string ()); @end example @section Usage @include defuns-cairo-version.xml.texi @c %end of fragment guile-cairo-1.10.0/doc/defuns-cairo-pdf.xml.texi0000644000175000017500000000441313256410550016302 00000000000000 @c %start of fragment @deffn Function cairo-pdf-surface-create (@var{filename}@tie{}@code{}) (@var{width-in-points}@tie{}@code{}) (@var{height-in-points}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Creates a PDF surface of the specified size in points to be written to @var{filename}. @table @var @item filename a filename for the PDF output (must be writable), @samp{@code{#f}} may be used to specify no output.

The toy API takes UTF-8 encoded text and is limited in its functionality to rendering simple left-to-right text with no advanced features. That means for example that most complex scripts like Hebrew, Arabic, and Indic scripts are out of question. No kerning or correct positioning of diacritical marks either. The font selection is pretty limited too and doesn't handle the case that the selected font does not cover the characters in the text. This set of functions are really that, a toy text API, for testing and demonstration purposes. Any serious application should avoid them. The functions with @emph{glyphs} in their name form cairo's @dfn{low-level} text API. The low-level API relies on the user to convert text to a set of glyph indexes and positions. This is a very hard problem and is best handled by external libraries, like the pangocairo that is part of the Pango text layout and rendering library.

To draw with cairo, you create a '', set the target surface, and drawing options for the '', create shapes with functions like 'cairo-move-to' and 'cairo-line-to', and then draw shapes with 'cairo-stroke' or 'cairo-fill'. '''s can be pushed to a stack via 'cairo-save'. They may then safely be changed, without loosing the current state. Use 'cairo-restore' to restore to the saved state. 1.2 Usage ========= -- Function: cairo-create (TARGET '') => (RET '') Creates a new '' with all graphics state parameters set to default values and with TARGET as a target surface. The target surface should be constructed with a backend-specific function such as 'cairo-image-surface-create' (or any other 'cairo__surface_create' variant). TARGET target surface for the context RET a newly allocated ''. -- Function: cairo-save (CR '') Makes a copy of the current state of CR and saves it on an internal stack of saved states for CR. When 'cairo-restore' is called, CR will be restored to the saved state. Multiple calls to 'cairo-save' and 'cairo-restore' can be nested; each call to 'cairo-restore' restores the state from the matching paired 'cairo-save'. It isn't necessary to clear all saved states before a '' is freed. If the reference count of a '' drops to zero in response to a call to 'cairo-destroy', any saved states will be freed along with the ''. CR a '' -- Function: cairo-restore (CR '') Restores CR to the state saved by a preceding call to 'cairo-save' and removes that state from the stack of saved states. CR a '' -- Function: cairo-get-target (CR '') => (RET '') Gets the target surface for the cairo context as passed to 'cairo-create'. This function will always return a valid pointer, but the result can be a "nil" surface if CR is already in an error state, (ie. 'cairo-status''!=''CAIRO_STATUS_SUCCESS'). A nil surface is indicated by 'cairo-surface-status''!=''CAIRO_STATUS_SUCCESS'. CR a cairo context RET the target surface. This object is owned by cairo. To keep a reference to it, you must call 'cairo-surface-reference'. -- Function: cairo-push-group (CR '') Temporarily redirects drawing to an intermediate surface known as a group. The redirection lasts until the group is completed by a call to 'cairo-pop-group' or 'cairo-pop-group-to-source'. These calls provide the result of any drawing to the group as a pattern, (either as an explicit object, or set as the source pattern). This group functionality can be convenient for performing intermediate compositing. One common use of a group is to render objects as opaque within the group, (so that they occlude each other), and then blend the result with translucence onto the destination. Groups can be nested arbitrarily deep by making balanced calls to 'cairo-push-group'/'cairo-pop-group'. Each call pushes/pops the new target group onto/from a stack. The 'cairo-push-group' function calls 'cairo-save' so that any changes to the graphics state will not be visible outside the group, (the pop_group functions call 'cairo-restore'). By default the intermediate group will have a content type of 'CAIRO_CONTENT_COLOR_ALPHA'. Other content types can be chosen for the group by using 'cairo-push-group-with-content' instead. As an example, here is how one might fill and stroke a path with translucence, but without any portion of the fill being visible under the stroke: cairo_push_group (cr); cairo_set_source (cr, fill_pattern); cairo_fill_preserve (cr); cairo_set_source (cr, stroke_pattern); cairo_stroke (cr); cairo_pop_group_to_source (cr); cairo_paint_with_alpha (cr, alpha); CR a cairo context Since 1.2 -- Function: cairo-pop-group (CR '') => (RET '') Terminates the redirection begun by a call to 'cairo-push-group' or 'cairo-push-group-with-content' and returns a new pattern containing the results of all drawing operations performed to the group. The 'cairo-pop-group' function calls 'cairo-restore', (balancing a call to 'cairo-save' by the push_group function), so that any changes to the graphics state will not be visible outside the group. CR a cairo context RET a newly created (surface) pattern containing the results of all drawing operations performed to the group. The caller owns the returned object and should call 'cairo-pattern-destroy' when finished with it. Since 1.2 -- Function: cairo-pop-group-to-source (CR '') Terminates the redirection begun by a call to 'cairo-push-group' or 'cairo-push-group-with-content' and installs the resulting pattern as the source pattern in the given cairo context. The behavior of this function is equivalent to the sequence of operations: cairo_pattern_t *group = cairo_pop_group (cr); cairo_set_source (cr, group); cairo_pattern_destroy (group); but is more convenient as their is no need for a variable to store the short-lived pointer to the pattern. The 'cairo-pop-group' function calls 'cairo-restore', (balancing a call to 'cairo-save' by the push_group function), so that any changes to the graphics state will not be visible outside the group. CR a cairo context Since 1.2 -- Function: cairo-get-group-target (CR '') => (RET '') Gets the current destination surface for the context. This is either the original target surface as passed to 'cairo-create' or the target surface for the current group as started by the most recent call to 'cairo-push-group' or 'cairo-push-group-with-content'. This function will always return a valid pointer, but the result can be a "nil" surface if CR is already in an error state, (ie. 'cairo-status''!=''CAIRO_STATUS_SUCCESS'). A nil surface is indicated by 'cairo-surface-status''!=''CAIRO_STATUS_SUCCESS'. CR a cairo context RET the target surface. This object is owned by cairo. To keep a reference to it, you must call 'cairo-surface-reference'. Since 1.2 -- Function: cairo-set-source-rgb (CR '') (RED '') (GREEN '') (BLUE '') Sets the source pattern within CR to an opaque color. This opaque color will then be used for any subsequent drawing operation until a new source pattern is set. The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped. The default source pattern is opaque black, (that is, it is equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, 0.0)). CR a cairo context RED red component of color GREEN green component of color BLUE blue component of color -- Function: cairo-set-source-rgba (CR '') (RED '') (GREEN '') (BLUE '') (ALPHA '') Sets the source pattern within CR to a translucent color. This color will then be used for any subsequent drawing operation until a new source pattern is set. The color and alpha components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped. The default source pattern is opaque black, (that is, it is equivalent to cairo_set_source_rgba(cr, 0.0, 0.0, 0.0, 1.0)). CR a cairo context RED red component of color GREEN green component of color BLUE blue component of color ALPHA alpha component of color -- Function: cairo-set-source (CR '') (SOURCE '') Sets the source pattern within CR to SOURCE. This pattern will then be used for any subsequent drawing operation until a new source pattern is set. Note: The pattern's transformation matrix will be locked to the user space in effect at the time of 'cairo-set-source'. This means that further modifications of the current transformation matrix will not affect the source pattern. See 'cairo-pattern-set-matrix'. The default source pattern is a solid pattern that is opaque black, (that is, it is equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, 0.0)). CR a cairo context SOURCE a '' to be used as the source for subsequent drawing operations. -- Function: cairo-set-source-surface (CR '') (SURFACE '') (X '') (Y '') This is a convenience function for creating a pattern from SURFACE and setting it as the source in CR with 'cairo-set-source'. The X and Y parameters give the user-space coordinate at which the surface origin should appear. (The surface origin is its upper-left corner before any transformation has been applied.) The X and Y parameters are negated and then set as translation values in the pattern matrix. Other than the initial translation pattern matrix, as described above, all other pattern attributes, (such as its extend mode), are set to the default values as in 'cairo-pattern-create-for-surface'. The resulting pattern can be queried with 'cairo-get-source' so that these attributes can be modified if desired, (eg. to create a repeating pattern with 'cairo-pattern-set-extend'). CR a cairo context SURFACE a surface to be used to set the source pattern X User-space X coordinate for surface origin Y User-space Y coordinate for surface origin -- Function: cairo-get-source (CR '') => (RET '') Gets the current source pattern for CR. CR a cairo context RET the current source pattern. This object is owned by cairo. To keep a reference to it, you must call 'cairo-pattern-reference'. -- Function: cairo-set-antialias (CR '') (ANTIALIAS '') Set the antialiasing mode of the rasterizer used for drawing shapes. This value is a hint, and a particular backend may or may not support a particular value. At the current time, no backend supports 'CAIRO_ANTIALIAS_SUBPIXEL' when drawing shapes. Note that this option does not affect text rendering, instead see 'cairo-font-options-set-antialias'. CR a '' ANTIALIAS the new antialiasing mode -- Function: cairo-get-antialias (CR '') => (RET '') Gets the current shape antialiasing mode, as set by 'cairo-set-shape-antialias'. CR a cairo context RET the current shape antialiasing mode. -- Function: cairo-set-dash (CR '') => (DASHES '') (NUM-DASHES '') (OFFSET '') Sets the dash pattern to be used by 'cairo-stroke'. A dash pattern is specified by DASHES, an array of positive values. Each value provides the length of alternate "on" and "off" portions of the stroke. The OFFSET specifies an offset into the pattern at which the stroke begins. Each "on" segment will have caps applied as if the segment were a separate sub-path. In particular, it is valid to use an "on" length of 0.0 with 'CAIRO_LINE_CAP_ROUND' or 'CAIRO_LINE_CAP_SQUARE' in order to distributed dots or squares along a path. Note: The length values are in user-space units as evaluated at the time of stroking. This is not necessarily the same as the user space at the time of 'cairo-set-dash'. If NUM-DASHES is 0 dashing is disabled. If NUM-DASHES is 1 a symmetric pattern is assumed with alternating on and off portions of the size specified by the single value in DASHES. If any value in DASHES is negative, or if all values are 0, then CR will be put into an error state with a status of 'CAIRO_STATUS_INVALID_DASH'. CR a cairo context DASHES an array specifying alternate lengths of on and off stroke portions NUM-DASHES the length of the dashes array OFFSET an offset into the dash pattern at which the stroke should start -- Function: cairo-get-dash-count (CR '') => (RET '') This function returns the length of the dash array in CR (0 if dashing is not currently in effect). See also 'cairo-set-dash' and 'cairo-get-dash'. CR a '' RET the length of the dash array, or 0 if no dash array set. Since 1.4 -- Function: cairo-set-fill-rule (CR '') (FILL-RULE '') Set the current fill rule within the cairo context. The fill rule is used to determine which regions are inside or outside a complex (potentially self-intersecting) path. The current fill rule affects both 'cairo-fill' and 'cairo-clip'. See '' for details on the semantics of each available fill rule. The default fill rule is 'CAIRO_FILL_RULE_WINDING'. CR a '' FILL-RULE a fill rule, specified as a '' -- Function: cairo-get-fill-rule (CR '') => (RET '') Gets the current fill rule, as set by 'cairo-set-fill-rule'. CR a cairo context RET the current fill rule. -- Function: cairo-set-line-cap (CR '') (LINE-CAP '') Sets the current line cap style within the cairo context. See '' for details about how the available line cap styles are drawn. As with the other stroke parameters, the current line cap style is examined by 'cairo-stroke', 'cairo-stroke-extents', and 'cairo-stroke-to-path', but does not have any effect during path construction. The default line cap style is 'CAIRO_LINE_CAP_BUTT'. CR a cairo context LINE-CAP a line cap style -- Function: cairo-get-line-cap (CR '') => (RET '') Gets the current line cap style, as set by 'cairo-set-line-cap'. CR a cairo context RET the current line cap style. -- Function: cairo-set-line-join (CR '') (LINE-JOIN '') Sets the current line join style within the cairo context. See '' for details about how the available line join styles are drawn. As with the other stroke parameters, the current line join style is examined by 'cairo-stroke', 'cairo-stroke-extents', and 'cairo-stroke-to-path', but does not have any effect during path construction. The default line join style is 'CAIRO_LINE_JOIN_MITER'. CR a cairo context LINE-JOIN a line join style -- Function: cairo-get-line-join (CR '') => (RET '') Gets the current line join style, as set by 'cairo-set-line-join'. CR a cairo context RET the current line join style. -- Function: cairo-set-line-width (CR '') (WIDTH '') Sets the current line width within the cairo context. The line width value specifies the diameter of a pen that is circular in user space, (though device-space pen may be an ellipse in general due to scaling/shear/rotation of the CTM). Note: When the description above refers to user space and CTM it refers to the user space and CTM in effect at the time of the stroking operation, not the user space and CTM in effect at the time of the call to 'cairo-set-line-width'. The simplest usage makes both of these spaces identical. That is, if there is no change to the CTM between a call to 'cairo-set-line-width' and the stroking operation, then one can just pass user-space values to 'cairo-set-line-width' and ignore this note. As with the other stroke parameters, the current line width is examined by 'cairo-stroke', 'cairo-stroke-extents', and 'cairo-stroke-to-path', but does not have any effect during path construction. The default line width value is 2.0. CR a '' WIDTH a line width -- Function: cairo-get-line-width (CR '') => (RET '') This function returns the current line width value exactly as set by 'cairo-set-line-width'. Note that the value is unchanged even if the CTM has changed between the calls to 'cairo-set-line-width' and 'cairo-get-line-width'. CR a cairo context RET the current line width. -- Function: cairo-set-miter-limit (CR '') (LIMIT '') Sets the current miter limit within the cairo context. If the current line join style is set to 'CAIRO_LINE_JOIN_MITER' (see 'cairo-set-line-join'), the miter limit is used to determine whether the lines should be joined with a bevel instead of a miter. Cairo divides the length of the miter by the line width. If the result is greater than the miter limit, the style is converted to a bevel. As with the other stroke parameters, the current line miter limit is examined by 'cairo-stroke', 'cairo-stroke-extents', and 'cairo-stroke-to-path', but does not have any effect during path construction. The default miter limit value is 10.0, which will convert joins with interior angles less than 11 degrees to bevels instead of miters. For reference, a miter limit of 2.0 makes the miter cutoff at 60 degrees, and a miter limit of 1.414 makes the cutoff at 90 degrees. A miter limit for a desired angle can be computed as: miter limit = 1/sin(angle/2) CR a cairo context LIMIT miter limit to set -- Function: cairo-get-miter-limit (CR '') => (RET '') Gets the current miter limit, as set by 'cairo-set-miter-limit'. CR a cairo context RET the current miter limit. -- Function: cairo-set-operator (CR '') (OP '') Sets the compositing operator to be used for all drawing operations. See '' for details on the semantics of each available compositing operator. The default operator is 'CAIRO_OPERATOR_OVER'. CR a '' OP a compositing operator, specified as a '' -- Function: cairo-get-operator (CR '') => (RET '') Gets the current compositing operator for a cairo context. CR a cairo context RET the current compositing operator. -- Function: cairo-set-tolerance (CR '') (TOLERANCE '') Sets the tolerance used when converting paths into trapezoids. Curved segments of the path will be subdivided until the maximum deviation between the original path and the polygonal approximation is less than TOLERANCE. The default value is 0.1. A larger value will give better performance, a smaller value, better appearance. (Reducing the value from the default value of 0.1 is unlikely to improve appearance significantly.) The accuracy of paths within Cairo is limited by the precision of its internal arithmetic, and the prescribed TOLERANCE is restricted to the smallest representable internal value. CR a '' TOLERANCE the tolerance, in device units (typically pixels) -- Function: cairo-get-tolerance (CR '') => (RET '') Gets the current tolerance value, as set by 'cairo-set-tolerance'. CR a cairo context RET the current tolerance value. -- Function: cairo-clip (CR '') Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by 'cairo-fill' and according to the current fill rule (see 'cairo-set-fill-rule'). After 'cairo-clip', the current path will be cleared from the cairo context. The current clip region affects all drawing operations by effectively masking out any changes to the surface that are outside the current clip region. Calling 'cairo-clip' can only make the clip region smaller, never larger. But the current clip is part of the graphics state, so a temporary restriction of the clip region can be achieved by calling 'cairo-clip' within a 'cairo-save'/'cairo-restore' pair. The only other means of increasing the size of the clip region is 'cairo-reset-clip'. CR a cairo context -- Function: cairo-clip-preserve (CR '') Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by 'cairo-fill' and according to the current fill rule (see 'cairo-set-fill-rule').

Since 1.10 -- Function: cairo-reset-clip (CR '') Reset the current clip region to its original, unrestricted state. That is, set the clip region to an infinitely large shape containing the target surface. Equivalently, if infinity is too hard to grasp, one can imagine the clip region being reset to the exact bounds of the target surface. Note that code meant to be reusable should not call 'cairo-reset-clip' as it will cause results unexpected by higher-level code which calls 'cairo-clip'. Consider using 'cairo-save' and 'cairo-restore' around 'cairo-clip' as a more robust means of temporarily restricting the clip region.

The status may have other values to indicate other errors.

Contrast with 'cairo-path-extents', which is similar, but returns non-zero extents for some paths with no inked area, (such as a simple line segment). Note that 'cairo-fill-extents' must necessarily do more work to compute the precise inked areas in light of the fill rule, so 'cairo-path-extents' may be more desirable for sake of performance if the non-inked path extents are desired.

Note: Degenerate segments and sub-paths are treated specially and provide a useful result. These can result in two different situations: 1. Zero-length "on" segments set in 'cairo-set-dash'. If the cap style is 'CAIRO_LINE_CAP_ROUND' or 'CAIRO_LINE_CAP_SQUARE' then these segments will be drawn as circular dots or squares respectively. In the case of 'CAIRO_LINE_CAP_SQUARE', the orientation of the squares is determined by the direction of the underlying path. 2. A sub-path created by 'cairo-move-to' followed by either a 'cairo-close-path' or one or more calls to 'cairo-line-to' to the same coordinate as the 'cairo-move-to'. If the cap style is 'CAIRO_LINE_CAP_ROUND' then these sub-paths will be drawn as circular dots. Note that in the case of 'CAIRO_LINE_CAP_SQUARE' a degenerate sub-path will not be drawn at all, (since the correct orientation is indeterminate). In no case will a cap style of 'CAIRO_LINE_CAP_BUTT' cause anything to be drawn in the case of either degenerate segments or sub-paths. CR a cairo context -- Function: cairo-stroke-preserve (CR '') A drawing operator that strokes the current path according to the current line width, line join, line cap, and dash settings. Unlike 'cairo-stroke', 'cairo-stroke-preserve' preserves the path within the cairo context.

Use 'cairo-show-page' if you want to get an empty page after the emission. This is a convenience function that simply calls 'cairo-surface-copy-page' on CR's target. CR a cairo context -- Function: cairo-show-page (CR '') Emits and clears the current page for backends that support multiple pages. Use 'cairo-copy-page' if you don't want to clear the page.

See '' for hints on how to iterate over the returned data structure. This function will always return a valid pointer, but the result will have no data ('data==''#f''' and 'num_data==0'), if either of the following conditions hold: 1. If there is insufficient memory to copy the path. In this case 'path->status' will be set to 'CAIRO_STATUS_NO_MEMORY'. 2. If CR is already in an error state. In this case 'path->status' will contain the same status that would be returned by 'cairo-status'. CR a cairo context RET the copy of the current path. The caller owns the returned object and should call 'cairo-path-destroy' when finished with it. -- Function: cairo-copy-path-flat (CR '') => (RET '') Gets a flattened copy of the current path and returns it to the user as a ''. See '' for hints on how to iterate over the returned data structure. This function is like 'cairo-copy-path' except that any curves in the path will be approximated with piecewise-linear approximations, (accurate to within the current tolerance value). That is, the result is guaranteed to not have any elements of type 'CAIRO_PATH_CURVE_TO' which will instead be replaced by a series of 'CAIRO_PATH_LINE_TO' elements. This function will always return a valid pointer, but the result will have no data ('data==''#f''' and 'num_data==0'), if either of the following conditions hold: 1. If there is insufficient memory to copy the path. In this case 'path->status' will be set to 'CAIRO_STATUS_NO_MEMORY'. 2. If CR is already in an error state. In this case 'path->status' will contain the same status that would be returned by 'cairo-status'. CR a cairo context RET the copy of the current path. The caller owns the returned object and should call 'cairo-path-destroy' when finished with it. -- Function: cairo-append-path (CR '') (PATH '') Append the PATH onto the current path. The PATH may be either the return value from one of 'cairo-copy-path' or 'cairo-copy-path-flat' or it may be constructed manually. See '' for details on how the path data structure should be initialized, and note that 'path->status' must be initialized to 'CAIRO_STATUS_SUCCESS'. CR a cairo context PATH path to be appended -- Function: cairo-has-current-point (CR '') => (RET '') Returns whether a current point is defined on the current path. See 'cairo-get-current-point' for details on the current point. CR a cairo context RET whether a current point is defined. Since 1.6 -- Function: cairo-get-current-point (CR '') => (X '') (Y '') Gets the current point of the current path, which is conceptually the final point reached by the path so far. The current point is returned in the user-space coordinate system. If there is no defined current point or if CR is in an error status, X and Y will both be set to 0.0. It is possible to check this in advance with 'cairo-has-current-point'. Most path construction functions alter the current point. See the following for details on how they affect the current point: 'cairo-new-path', 'cairo-new-sub-path', 'cairo-append-path', 'cairo-close-path', 'cairo-move-to', 'cairo-line-to', 'cairo-curve-to', 'cairo-rel-move-to', 'cairo-rel-line-to', 'cairo-rel-curve-to', 'cairo-arc', 'cairo-arc-negative', 'cairo-rectangle', 'cairo-text-path', 'cairo-glyph-path', 'cairo-stroke-to-path'. Some functions use and alter the current point but do not otherwise change current path: 'cairo-show-text'. Some functions unset the current path and as a result, current point: 'cairo-fill', 'cairo-stroke'. CR a cairo context X return value for X coordinate of the current point Y return value for Y coordinate of the current point -- Function: cairo-new-path (CR '') Clears the current path. After this call there will be no path and no current point. CR a cairo context -- Function: cairo-new-sub-path (CR '') Begin a new sub-path. Note that the existing path is not affected. After this call there will be no current point. In many cases, this call is not needed since new sub-paths are frequently started with 'cairo-move-to'. A call to 'cairo-new-sub-path' is particularly useful when beginning a new sub-path with one of the 'cairo-arc' calls. This makes things easier as it is no longer necessary to manually compute the arc's initial coordinates for a call to 'cairo-move-to'. CR a cairo context Since 1.2 -- Function: cairo-close-path (CR '') Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to 'cairo-move-to'), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path. The behavior of 'cairo-close-path' is distinct from simply calling 'cairo-line-to' with the equivalent coordinate in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead, there is a line join connecting the final and initial segments of the sub-path. If there is no current point before the call to 'cairo-close-path', this function will have no effect. Note: As of cairo version 1.2.4 any call to 'cairo-close-path' will place an explicit MOVE_TO element into the path immediately after the CLOSE_PATH element, (which can be seen in 'cairo-copy-path' for example). This can simplify path processing in some cases as it may not be necessary to save the "last move_to point" during processing as the MOVE_TO immediately after the CLOSE_PATH will provide that point. CR a cairo context -- Function: cairo-arc (CR '') (XC '') (YC '') (RADIUS '') (ANGLE1 '') (ANGLE2 '') Adds a circular arc of the given RADIUS to the current path. The arc is centered at (XC, YC), begins at ANGLE1 and proceeds in the direction of increasing angles to end at ANGLE2. If ANGLE2 is less than ANGLE1 it will be progressively increased by 2*M_PI until it is greater than ANGLE1. If there is a current point, an initial line segment will be added to the path to connect the current point to the beginning of the arc. If this initial line is undesired, it can be avoided by calling 'cairo-new-sub-path' before calling 'cairo-arc'. Angles are measured in radians. An angle of 0.0 is in the direction of the positive X axis (in user space). An angle of 'M_PI'/2.0 radians (90 degrees) is in the direction of the positive Y axis (in user space). Angles increase in the direction from the positive X axis toward the positive Y axis. So with the default transformation matrix, angles increase in a clockwise direction. (To convert from degrees to radians, use 'degrees * (M_PI / 180.)'.) This function gives the arc in the direction of increasing angles; see 'cairo-arc-negative' to get the arc in the direction of decreasing angles. The arc is circular in user space. To achieve an elliptical arc, you can scale the current transformation matrix by different amounts in the X and Y directions. For example, to draw an ellipse in the box given by X, Y, WIDTH, HEIGHT: cairo_save (cr); cairo_translate (cr, x + width / 2., y + height / 2.); cairo_scale (cr, width / 2., height / 2.); cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI); cairo_restore (cr); CR a cairo context XC X position of the center of the arc YC Y position of the center of the arc RADIUS the radius of the arc ANGLE1 the start angle, in radians ANGLE2 the end angle, in radians -- Function: cairo-arc-negative (CR '') (XC '') (YC '') (RADIUS '') (ANGLE1 '') (ANGLE2 '') Adds a circular arc of the given RADIUS to the current path. The arc is centered at (XC, YC), begins at ANGLE1 and proceeds in the direction of decreasing angles to end at ANGLE2. If ANGLE2 is greater than ANGLE1 it will be progressively decreased by 2*M_PI until it is less than ANGLE1. See 'cairo-arc' for more details. This function differs only in the direction of the arc between the two angles. CR a cairo context XC X position of the center of the arc YC Y position of the center of the arc RADIUS the radius of the arc ANGLE1 the start angle, in radians ANGLE2 the end angle, in radians -- Function: cairo-curve-to (CR '') (X1 '') (Y1 '') (X2 '') (Y2 '') (X3 '') (Y3 '') Adds a cubic Bézier spline to the path from the current point to position (X3, Y3) in user-space coordinates, using (X1, Y1) and (X2, Y2) as the control points. After this call the current point will be (X3, Y3). If there is no current point before the call to 'cairo-curve-to' this function will behave as if preceded by a call to cairo_move_to(CR, X1, Y1). CR a cairo context X1 the X coordinate of the first control point Y1 the Y coordinate of the first control point X2 the X coordinate of the second control point Y2 the Y coordinate of the second control point X3 the X coordinate of the end of the curve Y3 the Y coordinate of the end of the curve -- Function: cairo-line-to (CR '') (X '') (Y '') Adds a line to the path from the current point to position (X, Y) in user-space coordinates. After this call the current point will be (X, Y). If there is no current point before the call to 'cairo-line-to' this function will behave as cairo_move_to(CR, X, Y). CR a cairo context X the X coordinate of the end of the new line Y the Y coordinate of the end of the new line -- Function: cairo-move-to (CR '') (X '') (Y '') Begin a new sub-path. After this call the current point will be (X, Y). CR a cairo context X the X coordinate of the new position Y the Y coordinate of the new position -- Function: cairo-rectangle (CR '') (X '') (Y '') (WIDTH '') (HEIGHT '') Adds a closed sub-path rectangle of the given size to the current path at position (X, Y) in user-space coordinates. This function is logically equivalent to: cairo_move_to (cr, x, y); cairo_rel_line_to (cr, width, 0); cairo_rel_line_to (cr, 0, height); cairo_rel_line_to (cr, -width, 0); cairo_close_path (cr); CR a cairo context X the X coordinate of the top left corner of the rectangle Y the Y coordinate to the top left corner of the rectangle WIDTH the width of the rectangle HEIGHT the height of the rectangle -- Function: cairo-glyph-path (CR '') (GLYPHS '') (NUM-GLYPHS '') Adds closed paths for the glyphs to the current path. The generated path if filled, achieves an effect similar to that of 'cairo-show-glyphs'. CR a cairo context GLYPHS array of glyphs to show NUM-GLYPHS number of glyphs to show -- Function: cairo-text-path (CR '') (UTF8 '') Adds closed paths for text to the current path. The generated path if filled, achieves an effect similar to that of 'cairo-show-text'. Text conversion and positioning is done similar to 'cairo-show-text'. Like 'cairo-show-text', After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for chaining multiple calls to to 'cairo-text-path' without having to set current point in between. Note: The 'cairo-text-path' function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See 'cairo-glyph-path' for the "real" text path API in cairo.

All offsets are relative to the current point. Adds a cubic Bézier spline to the path from the current point to a point offset from the current point by (DX3, DY3), using points offset by (DX1, DY1) and (DX2, DY2) as the control points. After this call the current point will be offset by (DX3, DY3). Given a current point of (x, y), cairo_rel_curve_to(CR, DX1, DY1, DX2, DY2, DX3, DY3) is logically equivalent to cairo_curve_to(CR, x+DX1, y+DY1, x+DX2, y+DY2, x+DX3, y+DY3).

Adds a line to the path from the current point to a point that is offset from the current point by (DX, DY) in user space. After this call the current point will be offset by (DX, DY). Given a current point of (x, y), cairo_rel_line_to(CR, DX, DY) is logically equivalent to cairo_line_to(CR, x + DX, y + DY). It is an error to call this function with no current point.

Contrast with 'cairo-fill-extents' and 'cairo-stroke-extents' which return the extents of only the area that would be "inked" by the corresponding drawing operations. The result of 'cairo-path-extents' is defined as equivalent to the limit of 'cairo-stroke-extents' with 'CAIRO_LINE_CAP_ROUND' as the line width approaches 0.0, (but never reaching the empty-rectangle returned by 'cairo-stroke-extents' for a line width of 0.0). Specifically, this means that zero-area sub-paths such as 'cairo-move-to';'cairo-line-to' segments, (even degenerate cases where the coordinates to both calls are identical), will be considered as contributing to the extents.

The primary use of patterns is as the source for all cairo drawing operations, although they can also be used as masks, that is, as the brush too. A cairo pattern is created by using one of the many constructors, of the form cairo_pattern_create__type_() or implicitly through cairo_set_source__type_() functions. 3.2 Usage ========= -- Function: cairo-pattern-add-color-stop-rgb (PATTERN '') (OFFSET '') (RED '') (GREEN '') (BLUE '') Adds an opaque color stop to a gradient pattern. The offset specifies the location along the gradient's control vector. For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle. The color is specified in the same way as in 'cairo-set-source-rgb'. If two (or more) stops are specified with identical offset values, they will be sorted according to the order in which the stops are added, (stops added earlier will compare less than stops added later). This can be useful for reliably making sharp color transitions instead of the typical blend. Note: If the pattern is not a gradient pattern, (eg. a linear or radial pattern), then the pattern will be put into an error status with a status of 'CAIRO_STATUS_PATTERN_TYPE_MISMATCH'.

This matrix is a transformation from user space to pattern space. When a pattern is first created it always has the identity matrix for its transformation matrix, which means that pattern space is initially identical to user space. Important: Please note that the direction of this transformation matrix is from user space to pattern space. This means that if you imagine the flow from a pattern to user space (and on to device space), then coordinates in that flow will be transformed by the inverse of the pattern matrix. For example, if you want to make a pattern appear twice as large as it does by default the correct code to use is: cairo_matrix_init_scale (&matrix, 0.5, 0.5); cairo_pattern_set_matrix (pattern, &matrix); Meanwhile, using values of 2.0 rather than 0.5 in the code above would cause the pattern to appear at half of its default size. Also, please note the discussion of the user-space locking semantics of 'cairo-set-source'.

The toy API takes UTF-8 encoded text and is limited in its functionality to rendering simple left-to-right text with no advanced features. That means for example that most complex scripts like Hebrew, Arabic, and Indic scripts are out of question. No kerning or correct positioning of diacritical marks either. The font selection is pretty limited too and doesn't handle the case that the selected font does not cover the characters in the text. This set of functions are really that, a toy text API, for testing and demonstration purposes. Any serious application should avoid them. The functions with _glyphs_ in their name form cairo's "low-level" text API. The low-level API relies on the user to convert text to a set of glyph indexes and positions. This is a very hard problem and is best handled by external libraries, like the pangocairo that is part of the Pango text layout and rendering library. Pango is available from http://www.pango.org/ (http://www.pango.org/). 6.2 Usage ========= -- Function: cairo-select-font-face (CR '') (FAMILY '') (SLANT '') (WEIGHT '') Note: The 'cairo-select-font-face' function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. Selects a family and style of font from a simplified description as a family name, slant and weight. Cairo provides no operation to list available family names on the system (this is a "toy", remember), but the standard CSS2 generic family names, ("serif", "sans-serif", "cursive", "fantasy", "monospace"), are likely to work as expected. If FAMILY starts with the string "CAIRO:", or if no native font backends are compiled in, cairo will use an internal font family. The internal font family recognizes many modifiers in the FAMILY string, most notably, it recognizes the string "monospace". That is, the family name "CAIRO:monospace" will use the monospace version of the internal font family. For "real" font selection, see the font-backend-specific font_face_create functions for the font backend you are using. (For example, if you are using the freetype-based cairo-ft font backend, see 'cairo-ft-font-face-create-for-ft-face' or 'cairo-ft-font-face-create-for-pattern'.) The resulting font face could then be used with 'cairo-scaled-font-create' and 'cairo-set-scaled-font'. Similarly, when using the "real" font support, you can call directly into the underlying font system, (such as fontconfig or freetype), for operations such as listing available fonts, etc. It is expected that most applications will need to use a more comprehensive font handling and text layout library, (for example, pango), in conjunction with cairo. If text is drawn without a call to 'cairo-select-font-face', (nor 'cairo-set-font-face' nor 'cairo-set-scaled-font'), the default family is platform-specific, but is essentially "sans-serif". Default slant is 'CAIRO_FONT_SLANT_NORMAL', and default weight is 'CAIRO_FONT_WEIGHT_NORMAL'. This function is equivalent to a call to 'cairo-toy-font-face-create' followed by 'cairo-set-font-face'. CR a '' FAMILY a font family name, encoded in UTF-8 SLANT the slant for the font WEIGHT the weight for the font -- Function: cairo-set-font-size (CR '') (SIZE '') Sets the current font matrix to a scale by a factor of SIZE, replacing any font matrix previously set with 'cairo-set-font-size' or 'cairo-set-font-matrix'. This results in a font size of SIZE user space units. (More precisely, this matrix will result in the font's em-square being a SIZE by SIZE square in user space.) If text is drawn without a call to 'cairo-set-font-size', (nor 'cairo-set-font-matrix' nor 'cairo-set-scaled-font'), the default font size is 10.0. CR a '' SIZE the new font size, in user space units -- Function: cairo-set-font-matrix (CR '') (MATRIX '') Sets the current font matrix to MATRIX. The font matrix gives a transformation from the design space of the font (in this space, the em-square is 1 unit by 1 unit) to user space. Normally, a simple scale is used (see 'cairo-set-font-size'), but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes CR a '' MATRIX a '' describing a transform to be applied to the current font. -- Function: cairo-get-font-matrix (CR '') (MATRIX '') Stores the current font matrix into MATRIX. See 'cairo-set-font-matrix'. CR a '' MATRIX return value for the matrix -- Function: cairo-set-font-options (CR '') (OPTIONS '') Sets a set of custom font rendering options for the ''. Rendering options are derived by merging these options with the options derived from underlying surface; if the value in OPTIONS has a default value (like 'CAIRO_ANTIALIAS_DEFAULT'), then the value from the surface is used. CR a '' OPTIONS font options to use -- Function: cairo-get-font-options (CR '') (OPTIONS '') Retrieves font rendering options set via ''. Note that the returned options do not include any options derived from the underlying surface; they are literally the options passed to 'cairo-set-font-options'. CR a '' OPTIONS a '' object into which to store the retrieved options. All existing values are overwritten -- Function: cairo-set-font-face (CR '') (FONT-FACE '') Replaces the current '' object in the '' with FONT-FACE. The replaced font face in the '' will be destroyed if there are no other references to it. CR a '' FONT-FACE a '', or ''#f'' to restore to the default font -- Function: cairo-get-font-face (CR '') => (RET '') Gets the current font face for a ''. CR a '' RET the current font face. This object is owned by cairo. To keep a reference to it, you must call 'cairo-font-face-reference'. This function never returns ''#f''. If memory cannot be allocated, a special "nil" '' object will be returned on which 'cairo-font-face-status' returns 'CAIRO_STATUS_NO_MEMORY'. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling 'cairo-set-font-face' with a nil font will trigger an error that will shutdown the '' object). -- Function: cairo-set-scaled-font (CR '') (SCALED-FONT '') Replaces the current font face, font matrix, and font options in the '' with those of the ''. Except for some translation, the current CTM of the '' should be the same as that of the '', which can be accessed using 'cairo-scaled-font-get-ctm'. CR a '' SCALED-FONT a '' Since 1.2 -- Function: cairo-get-scaled-font (CR '') => (RET '') Gets the current scaled font for a ''. CR a '' RET the current scaled font. This object is owned by cairo. To keep a reference to it, you must call 'cairo-scaled-font-reference'. This function never returns ''#f''. If memory cannot be allocated, a special "nil" '' object will be returned on which 'cairo-scaled-font-status' returns 'CAIRO_STATUS_NO_MEMORY'. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling 'cairo-set-scaled-font' with a nil font will trigger an error that will shutdown the '' object). Since 1.4 -- Function: cairo-show-text (CR '') (UTF8 '') A drawing operator that generates the shape from a string of UTF-8 characters, rendered according to the current font_face, font_size (font_matrix), and font_options. This function first computes a set of glyphs for the string of text. The first glyph is placed so that its origin is at the current point. The origin of each subsequent glyph is offset from that of the previous glyph by the advance values of the previous glyph. After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for easy display of a single logical string with multiple calls to 'cairo-show-text'. Note: The 'cairo-show-text' function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See 'cairo-show-glyphs' for the "real" text display API in cairo. CR a cairo context UTF8 a NUL-terminated string of text encoded in UTF-8, or ''#f'' -- Function: cairo-show-glyphs (CR '') (GLYPHS '') (NUM-GLYPHS '') A drawing operator that generates the shape from an array of glyphs, rendered according to the current font face, font size (font matrix), and font options. CR a cairo context GLYPHS array of glyphs to show NUM-GLYPHS number of glyphs to show -- Function: cairo-show-text-glyphs (CR '') (UTF8 '') (UTF8-LEN '') (GLYPHS '') (NUM-GLYPHS '') (CLUSTERS '') (NUM-CLUSTERS '') (CLUSTER-FLAGS '') This operation has rendering effects similar to 'cairo-show-glyphs' but, if the target surface supports it, uses the provided text and cluster mapping to embed the text for the glyphs shown in the output. If the target does not support the extended attributes, this function acts like the basic 'cairo-show-glyphs' as if it had been passed GLYPHS and NUM-GLYPHS. The mapping between UTF8 and GLYPHS is provided by an array of "clusters". Each cluster covers a number of text bytes and glyphs, and neighboring clusters cover neighboring areas of UTF8 and GLYPHS. The clusters should collectively cover UTF8 and GLYPHS in entirety. The first cluster always covers bytes from the beginning of UTF8. If CLUSTER-FLAGS do not have the 'CAIRO_TEXT_CLUSTER_FLAG_BACKWARD' set, the first cluster also covers the beginning of GLYPHS, otherwise it covers the end of the GLYPHS array and following clusters move backward. See '' for constraints on valid clusters. CR a cairo context UTF8 a string of text encoded in UTF-8 UTF8-LEN length of UTF8 in bytes, or -1 if it is NUL-terminated GLYPHS array of glyphs to show NUM-GLYPHS number of glyphs to show CLUSTERS array of cluster mapping information NUM-CLUSTERS number of clusters in the mapping CLUSTER-FLAGS cluster mapping flags Since 1.8 -- Function: cairo-font-extents (CR '') (EXTENTS '') Gets the font extents for the currently selected font. CR a '' EXTENTS a '' object into which the results will be stored. -- Function: cairo-text-extents (CR '') (UTF8 '') (EXTENTS '') Gets the extents for a string of text. The extents describe a user-space rectangle that encloses the "inked" portion of the text, (as it would be drawn by 'cairo-show-text'). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by 'cairo-show-text'. Note that whitespace characters do not directly contribute to the size of the rectangle (extents.width and extents.height). They do contribute indirectly by changing the position of non-whitespace characters. In particular, trailing whitespace characters are likely to not affect the size of the rectangle, though they will affect the x_advance and y_advance values. CR a '' UTF8 a NUL-terminated string of text encoded in UTF-8, or ''#f'' EXTENTS a '' object into which the results will be stored -- Function: cairo-glyph-extents (CR '') (GLYPHS '') (NUM-GLYPHS '') (EXTENTS '') Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by 'cairo-show-glyphs'). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by 'cairo-show-glyphs'. Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height). CR a '' GLYPHS an array of '' objects NUM-GLYPHS the number of elements in GLYPHS EXTENTS a '' object into which the results will be stored -- Function: cairo-toy-font-face-create (FAMILY '') (SLANT '') (WEIGHT '') => (RET '') Creates a font face from a triplet of family, slant, and weight. These font faces are used in implementation of the the '' "toy" font API. If FAMILY is the zero-length string "", the platform-specific default family is assumed.

Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by 'cairo-show-text'.

SCALED-FONT a '' UTF8 a NUL-terminated string of text, encoded in UTF-8 EXTENTS a '' which to store the retrieved extents. Since 1.2 -- Function: cairo-scaled-font-glyph-extents (SCALED-FONT '') (GLYPHS '') (NUM-GLYPHS '') (EXTENTS '') Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by 'cairo-show-glyphs' if the cairo graphics state were set to the same font_face, font_matrix, ctm, and font_options as SCALED-FONT). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by 'cairo-show-glyphs'. Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height). SCALED-FONT a '' GLYPHS an array of glyph IDs with X and Y offsets.

If GLYPHS initially points to a non-''#f'' value, that array is used as a glyph buffer, and NUM-GLYPHS should point to the number of glyph entries available there. If the provided glyph array is too short for the conversion, a new glyph array is allocated using 'cairo-glyph-allocate' and placed in GLYPHS. Upon return, NUM-GLYPHS always contains the number of generated glyphs. If the value GLYPHS points to has changed after the call, the user is responsible for freeing the allocated glyph array using 'cairo-glyph-free'. This may happen even if the provided array was large enough. If CLUSTERS is not ''#f'', NUM-CLUSTERS and CLUSTER-FLAGS should not be ''#f'', and cluster mapping will be computed. The semantics of how cluster array allocation works is similar to the glyph array. That is, if CLUSTERS initially points to a non-''#f'' value, that array is used as a cluster buffer, and NUM-CLUSTERS should point to the number of cluster entries available there. If the provided cluster array is too short for the conversion, a new cluster array is allocated using 'cairo-text-cluster-allocate' and placed in CLUSTERS. Upon return, NUM-CLUSTERS always contains the number of generated clusters. If the value CLUSTERS points at has changed after the call, the user is responsible for freeing the allocated cluster array using 'cairo-text-cluster-free'. This may happen even if the provided array was large enough. In the simplest case, GLYPHS and CLUSTERS can point to ''#f'' initially and a suitable array will be allocated.

Use the setter functions to associate callbacks with the returned user font. The only mandatory callback is render_glyph. After the font-face is created, the user can attach arbitrary data (the actual font data) to it using 'cairo-font-face-set-user-data' and access it from the user-font callbacks by using 'cairo-scaled-font-get-font-face' followed by 'cairo-font-face-get-user-data'.

You can get the device of a surface using 'cairo-surface-get-device'. Devices are created using custom functions specific to the rendering system you want to use. See the documentation for the surface types for those functions. An important function that devices fulfill is sharing access to the rendering system between Cairo and your application. If you want to access a device directly that you used to draw to with Cairo, you must first call 'cairo-device-flush' to ensure that Cairo finishes all operations on the device and resets it to a clean state. Cairo also provides the functions 'cairo-device-acquire' and 'cairo-device-release' to synchronize access to the rendering system in a multithreaded environment. This is done internally, but can also be used by applications. Putting this all together, a function that works with devices should look something like this: void my_device_modifying_function (cairo_device_t *device) { cairo_status_t status; // Ensure the device is properly reset cairo_device_flush (device); // Try to acquire the device status = cairo_device_acquire (device); if (status != CAIRO_STATUS_SUCCESS) { printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status)); return; } // Do the custom operations on the device here. // But do not call any Cairo functions that might acquire devices. // Release the device when done. cairo_device_release (device); } Please refer to the documentation of each backend for additional usage requirements, guarantees provided, and interactions with existing surface API of the device functions for surfaces of that type. 14.2 Usage ========== -- Function: cairo-device-finish (DEVICE '') This function finishes the device and drops all references to external resources. All surfaces, fonts and other objects created for this DEVICE will be finished, too. Further operations on the DEVICE will not affect the DEVICE but will instead trigger a 'CAIRO_STATUS_DEVICE_FINISHED' error. When the last call to 'cairo-device-destroy' decreases the reference count to zero, cairo will call 'cairo-device-finish' if it hasn't been called already, before freeing the resources associated with the device. This function may acquire devices. DEVICE the '' to finish Since 1.10 -- Function: cairo-device-flush (DEVICE '') Finish any pending operations for the device and also restore any temporary modifications cairo has made to the device's state. This function must be called before switching from using the device with Cairo to operating on it directly with native APIs. If the device doesn't support direct access, then this function does nothing. This function may acquire devices. DEVICE a '' Since 1.10 -- Function: cairo-device-get-type (DEVICE '') => (RET '') This function returns the type of the device. See '' for available types. DEVICE a '' RET The type of DEVICE. Since 1.10 -- Function: cairo-device-acquire (DEVICE '') => (RET '') Acquires the DEVICE for the current thread. This function will block until no other thread has acquired the device. If the return value is 'CAIRO_STATUS_SUCCESS', you successfully acquired the device. From now on your thread owns the device and no other thread will be able to acquire it until a matching call to 'cairo-device-release'. It is allowed to recursively acquire the device multiple times from the same thread. You must never acquire two different devices at the same time unless this is explicitly allowed. Otherwise the possibility of deadlocks exist. As various Cairo functions can acquire devices when called, these functions may also cause deadlocks when you call them with an acquired device. So you must not have a device acquired when calling them. These functions are marked in the documentation. DEVICE a '' RET 'CAIRO_STATUS_SUCCESS' on success or an error code if the device is in an error state and could not be acquired. After a successful call to 'cairo-device-acquire', a matching call to 'cairo-device-release' is required. Since 1.10 -- Function: cairo-device-release (DEVICE '') Releases a DEVICE previously acquired using 'cairo-device-acquire'. See that function for details.

The actual drawings are performed using a cairo "context". A cairo surface is created by using "backend"-specific constructors, typically of the form cairo__backend_'-surface-create'. Most surface types allow accessing the surface without using Cairo functions. If you do this, keep in mind that it is mandatory that you call 'cairo-surface-flush' before reading from or writing to the surface and that you must use 'cairo-surface-mark-dirty' after modifying it. Note that for other surface types it might be necessary to acquire the surface's device first. See 'cairo-device-acquire' for a discussion of devices. void modify_image_surface (cairo_surface_t *surface) { unsigned char *data; int width, height, stride; // flush to ensure all writing to the image was done cairo_surface_flush (surface); // modify the image data = cairo_image_surface_get_data (surface); width = cairo_image_surface_get_width (surface); height = cairo_image_surface_get_height (surface); stride = cairo_image_surface_get_stride (surface); modify_image_data (data, width, height, stride); // mark the image dirty so Cairo clears its caches. cairo_surface_mark_dirty (surface); } 15.2 Usage ========== -- Function: cairo-surface-create-similar (OTHER '') (CONTENT '') (WIDTH '') (HEIGHT '') => (RET '') Create a new surface that is as compatible as possible with an existing surface. For example the new surface will have the same fallback resolution and font options as OTHER. Generally, the new surface will also use the same backend as OTHER, unless that is not possible for some reason. The type of the returned surface may be examined with 'cairo-surface-get-type'. Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.) OTHER an existing surface used to select the backend of the new surface CONTENT the content for the new surface WIDTH width of the new surface, (in device-space units) HEIGHT height of the new surface (in device-space units) RET a pointer to the newly allocated surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if OTHER is already in an error state or any other error occurs. -- Function: cairo-surface-create-for-rectangle (TARGET '') (X '') (Y '') (WIDTH '') (HEIGHT '') => (RET '') Create a new surface that is a rectangle within the target surface. All operations drawn to this surface are then clipped and translated onto the target surface. Nothing drawn via this sub-surface outside of its bounds is drawn onto the target surface, making this a useful method for passing constrained child surfaces to library routines that draw directly onto the parent surface, i.e. with no further backend allocations, double buffering or copies. The semantics of subsurfaces have not been finalized yet unless the rectangle is in full device units, is contained within the extents of the target surface, and the target or subsurface's device transforms are not changed. TARGET an existing surface for which the sub-surface will point to X the x-origin of the sub-surface from the top-left of the target surface (in device-space units) Y the y-origin of the sub-surface from the top-left of the target surface (in device-space units) WIDTH width of the sub-surface (in device-space units) HEIGHT height of the sub-surface (in device-space units) RET a pointer to the newly allocated surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if OTHER is already in an error state or any other error occurs. Since 1.10 -- Function: cairo-surface-finish (SURFACE '') This function finishes the surface and drops all references to external resources. For example, for the Xlib backend it means that cairo will no longer access the drawable, which can be freed. After calling 'cairo-surface-finish' the only valid operations on a surface are getting and setting user, referencing and destroying, and flushing and finishing it. Further drawing to the surface will not affect the surface but will instead trigger a 'CAIRO_STATUS_SURFACE_FINISHED' error. When the last call to 'cairo-surface-destroy' decreases the reference count to zero, cairo will call 'cairo-surface-finish' if it hasn't been called already, before freeing the resources associated with the surface. SURFACE the '' to finish -- Function: cairo-surface-flush (SURFACE '') Do any pending drawing for the surface and also restore any temporary modifications cairo has made to the surface's state. This function must be called before switching from drawing on the surface with cairo to drawing on it directly with native APIs. If the surface doesn't support direct access, then this function does nothing. SURFACE a '' -- Function: cairo-surface-get-device (SURFACE '') => (RET '') This function returns the device for a SURFACE. See ''. SURFACE a '' RET The device for SURFACE or ''#f'' if the surface does not have an associated device. Since 1.10 -- Function: cairo-surface-get-font-options (SURFACE '') (OPTIONS '') Retrieves the default font rendering options for the surface. This allows display surfaces to report the correct subpixel order for rendering on them, print surfaces to disable hinting of metrics and so forth. The result can then be used with 'cairo-scaled-font-create'. SURFACE a '' OPTIONS a '' object into which to store the retrieved options. All existing values are overwritten -- Function: cairo-surface-get-content (SURFACE '') => (RET '') This function returns the content type of SURFACE which indicates whether the surface contains color and/or alpha information. See ''. SURFACE a '' RET The content type of SURFACE. Since 1.2 -- Function: cairo-surface-mark-dirty (SURFACE '') Tells cairo that drawing has been done to surface using means other than cairo, and that cairo should reread any cached areas. Note that you must call 'cairo-surface-flush' before doing such drawing. SURFACE a '' -- Function: cairo-surface-mark-dirty-rectangle (SURFACE '') (X '') (Y '') (WIDTH '') (HEIGHT '') Like 'cairo-surface-mark-dirty', but drawing has been done only to the specified rectangle, so that cairo can retain cached contents for other parts of the surface. Any cached clip set on the surface will be reset by this function, to make sure that future cairo calls have the clip set that they expect. SURFACE a '' X X coordinate of dirty rectangle Y Y coordinate of dirty rectangle WIDTH width of dirty rectangle HEIGHT height of dirty rectangle -- Function: cairo-surface-set-device-offset (SURFACE '') (X-OFFSET '') (Y-OFFSET '') Sets an offset that is added to the device coordinates determined by the CTM when drawing to SURFACE. One use case for this function is when we want to create a '' that redirects drawing for a portion of an onscreen surface to an offscreen surface in a way that is completely invisible to the user of the cairo API. Setting a transformation via 'cairo-translate' isn't sufficient to do this, since functions like 'cairo-device-to-user' will expose the hidden offset. Note that the offset affects drawing to the surface as well as using the surface in a source pattern. SURFACE a '' X-OFFSET the offset in the X direction, in device units Y-OFFSET the offset in the Y direction, in device units -- Function: cairo-surface-get-device-offset (SURFACE '') => (X-OFFSET '') (Y-OFFSET '') This function returns the previous device offset set by 'cairo-surface-set-device-offset'. SURFACE a '' X-OFFSET the offset in the X direction, in device units Y-OFFSET the offset in the Y direction, in device units Since 1.2 -- Function: cairo-surface-get-type (SURFACE '') => (RET '') This function returns the type of the backend used to create a surface.

SURFACE a '' Since 1.6 -- Function: cairo-surface-has-show-text-glyphs (SURFACE '') => (RET '') Returns whether the surface supports sophisticated 'cairo-show-text-glyphs' operations. That is, whether it actually uses the provided text and cluster data to a 'cairo-show-text-glyphs' call. Note: Even if this function returns ''#f'', a 'cairo-show-text-glyphs' operation targeted at SURFACE will still succeed. It just will act like a 'cairo-show-glyphs' operation. Users can use this function to avoid computing UTF-8 text and cluster mapping if the target surface does not use it.

The contents of bits within a pixel, but not belonging to the given format are undefined). FORMAT format of pixels in the surface to create WIDTH width of the surface, in pixels HEIGHT height of the surface, in pixels RET a pointer to the newly created surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use 'cairo-surface-status' to check for this. -- Function: cairo-image-surface-get-format (SURFACE '') => (RET '') Get the format of the surface.

FILENAME a filename for the PDF output (must be writable), ''#f'' may be used to specify no output. This will generate a PDF surface that may be queried and used as a source, without generating a temporary file. WIDTH-IN-POINTS width of the surface, in points (1 point == 1/72.0 inch) HEIGHT-IN-POINTS height of the surface, in points (1 point == 1/72.0 inch) RET a pointer to the newly created surface.

FILENAME name of PNG file to load RET a new '' initialized with the contents of the PNG file, or a "nil" surface if any error occurred. A nil surface can be checked for with cairo_surface_status(surface) which may return one of the following values: 'CAIRO_STATUS_NO_MEMORY''CAIRO_STATUS_FILE_NOT_FOUND''CAI RO_STATUS_READ_ERROR' Alternatively, you can allow errors to propagate through the drawing operations and check the status on the context upon completion using 'cairo-status'. -- Function: cairo-surface-write-to-png (SURFACE '') (FILENAME '') => (RET '') Writes the contents of SURFACE to a new file FILENAME as a PNG image. SURFACE a '' with pixel contents FILENAME the name of a file to write to RET 'CAIRO_STATUS_SUCCESS' if the PNG file was written successfully. Otherwise, 'CAIRO_STATUS_NO_MEMORY' if memory could not be allocated for the operation or 'CAIRO_STATUS_SURFACE_TYPE_MISMATCH' if the surface does not have pixel contents, or 'CAIRO_STATUS_WRITE_ERROR' if an I/O error occurs while attempting to write the file.

See 'cairo-ps-surface-create-for-stream' for a more flexible mechanism for handling the PostScript output than simply writing it to a named file. Note that the size of individual pages of the PostScript output can vary. See 'cairo-ps-surface-set-size'. FILENAME a filename for the PS output (must be writable), ''#f'' may be used to specify no output. This will generate a PS surface that may be queried and used as a source, without generating a temporary file. WIDTH-IN-POINTS width of the surface, in points (1 point == 1/72.0 inch) HEIGHT-IN-POINTS height of the surface, in points (1 point == 1/72.0 inch) RET a pointer to the newly created surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use 'cairo-surface-status' to check for this. Since 1.2 -- Function: cairo-ps-surface-restrict-to-level (SURFACE '') (LEVEL '') Restricts the generated PostSript file to LEVEL. See 'cairo-ps-get-levels' for a list of available level values that can be used here. This function should only be called before any drawing operations have been performed on the given surface. The simplest way to do this is to call this function immediately after creating the surface. SURFACE a PostScript '' LEVEL PostScript level Since 1.6 -- Function: cairo-ps-get-levels => (LEVELS '') (NUM-LEVELS '') Used to retrieve the list of supported levels. See 'cairo-ps-surface-restrict-to-level'. LEVELS supported level list NUM-LEVELS list length Since 1.6 -- Function: cairo-ps-surface-set-eps (SURFACE '') (EPS '') If EPS is ''#t'', the PostScript surface will output Encapsulated PostScript. This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface. An Encapsulated PostScript file should never contain more than one page. SURFACE a PostScript '' EPS ''#t'' to output EPS format PostScript Since 1.6 -- Function: cairo-ps-surface-get-eps (SURFACE '') => (RET '') Check whether the PostScript surface will output Encapsulated PostScript. SURFACE a PostScript '' RET ''#t'' if the surface will output Encapsulated PostScript. Since 1.6 -- Function: cairo-ps-surface-set-size (SURFACE '') (WIDTH-IN-POINTS '') (HEIGHT-IN-POINTS '') Changes the size of a PostScript surface for the current (and subsequent) pages. This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface or immediately after completing a page with either 'cairo-show-page' or 'cairo-copy-page'. SURFACE a PostScript '' WIDTH-IN-POINTS new surface width, in points (1 point == 1/72.0 inch) HEIGHT-IN-POINTS new surface height, in points (1 point == 1/72.0 inch) Since 1.2 -- Function: cairo-ps-surface-dsc-comment (SURFACE '') (COMMENT '') Emit a comment into the PostScript output for the given surface. The comment is expected to conform to the PostScript Language Document Structuring Conventions (DSC). Please see that manual for details on the available comments and their meanings. In particular, the %'IncludeFeature' comment allows a device-independent means of controlling printer device features. So the PostScript Printer Description Files Specification will also be a useful reference. The comment string must begin with a percent character (%) and the total length of the string (including any initial percent characters) must not exceed 255 characters. Violating either of these conditions will place SURFACE into an error state. But beyond these two conditions, this function will not enforce conformance of the comment with any particular specification. The comment string should not have a trailing newline. The DSC specifies different sections in which particular comments can appear. This function provides for comments to be emitted within three sections: the header, the Setup section, and the PageSetup section. Comments appearing in the first two sections apply to the entire document while comments in the BeginPageSetup section apply only to a single page. For comments to appear in the header section, this function should be called after the surface is created, but before a call to 'cairo-ps-surface-begin-setup'. For comments to appear in the Setup section, this function should be called after a call to 'cairo-ps-surface-begin-setup' but before a call to 'cairo-ps-surface-begin-page-setup'. For comments to appear in the PageSetup section, this function should be called after a call to 'cairo-ps-surface-begin-page-setup'. Note that it is only necessary to call 'cairo-ps-surface-begin-page-setup' for the first page of any surface. After a call to 'cairo-show-page' or 'cairo-copy-page' comments are unambiguously directed to the PageSetup section of the current page. But it doesn't hurt to call this function at the beginning of every page as that consistency may make the calling code simpler. As a final note, cairo automatically generates several comments on its own. As such, applications must not manually generate any of the following comments: Header section: %!PS-Adobe-3.0, %'Creator', %'CreationDate', %'Pages', %'BoundingBox', %'DocumentData', %'LanguageLevel', %'EndComments'. Setup section: %'BeginSetup', %'EndSetup' PageSetup section: %'BeginPageSetup', %'PageBoundingBox', %'EndPageSetup'. Other sections: %'BeginProlog', %'EndProlog', %'Page', %'Trailer', %'EOF' Here is an example sequence showing how this function might be used: cairo_surface_t *surface = cairo_ps_surface_create (filename, width, height); ... cairo_ps_surface_dsc_comment (surface, "%%Title: My excellent document"); cairo_ps_surface_dsc_comment (surface, "%%Copyright: Copyright (C) 2006 Cairo Lover") ... cairo_ps_surface_dsc_begin_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor White"); ... cairo_ps_surface_dsc_begin_page_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A3"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *InputSlot LargeCapacity"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaType Glossy"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor Blue"); ... draw to first page here .. cairo_show_page (cr); ... cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A5"); ...

The recording surface can then be "replayed" against any target surface by using it as a source surface. If you want to replay a surface so that the results in target will be identical to the results that would have been obtained if the original operations applied to the recording surface had instead been applied to the target surface, you can use code like this: cairo_t *cr; cr = cairo_create (target); cairo_set_source_surface (cr, recording_surface, 0.0, 0.0); cairo_paint (cr); cairo_destroy (cr); A recording surface is logically unbounded, i.e. it has no implicit constraint on the size of the drawing surface. However, in practice this is rarely useful as you wish to replay against a particular target surface with known bounds. For this case, it is more efficient to specify the target extents to the recording surface upon creation. The recording phase of the recording surface is careful to snapshot all necessary objects (paths, patterns, etc.), in order to achieve accurate replay. The efficiency of the recording surface could be improved by improving the implementation of snapshot for the various objects. For example, it would be nice to have a copy-on-write implementation for _cairo_surface_snapshot. 20.2 Usage ========== -- Function: cairo-recording-surface-create (CONTENT '') (EXTENTS '') => (RET '') Creates a recording-surface which can be used to record all drawing operations at the highest level (that is, the level of paint, mask, stroke, fill and show_text_glyphs). The recording surface can then be "replayed" against any target surface by using it as a source to drawing operations. The recording phase of the recording surface is careful to snapshot all necessary objects (paths, patterns, etc.), in order to achieve accurate replay. CONTENT the content of the recording surface EXTENTS the extents to record in pixels, can be ''#f'' to record unbounded operations. RET a pointer to the newly created surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. Since 1.10 -- Function: cairo-recording-surface-ink-extents (SURFACE '') => (X0 '') (Y0 '') (WIDTH '') (HEIGHT '') Measures the extents of the operations stored within the recording-surface. This is useful to compute the required size of an image surface (or equivalent) into which to replay the full sequence of drawing operations. SURFACE a '' X0 the x-coordinate of the top-left of the ink bounding box Y0 the y-coordinate of the top-left of the ink bounding box WIDTH the width of the ink bounding box HEIGHT the height of the ink bounding box Since 1.10  File: guile-cairo.info, Node: SVG Surfaces, Next: cairo_matrix_t, Prev: Recording Surfaces, Up: Top 21 SVG Surfaces *************** Rendering SVG documents 21.1 Overview ============= The SVG surface is used to render cairo graphics to SVG files and is a multi-page vector surface backend. 21.2 Usage ========== -- Function: cairo-svg-surface-create (FILENAME '') (WIDTH-IN-POINTS '') (HEIGHT-IN-POINTS '') => (RET '') Creates a SVG surface of the specified size in points to be written to FILENAME. The SVG surface backend recognizes the following MIME types for the data attached to a surface (see 'cairo-surface-set-mime-data') when it is used as a source pattern for drawing on this surface: 'CAIRO_MIME_TYPE_JPEG', 'CAIRO_MIME_TYPE_PNG', 'CAIRO_MIME_TYPE_URI'. If any of them is specified, the SVG backend emits a href with the content of MIME data instead of a surface snapshot (PNG, Base64-encoded) in the corresponding image tag. The unofficial MIME type 'CAIRO_MIME_TYPE_URI' is examined first. If present, the URI is emitted as is: assuring the correctness of URI is left to the client code. If 'CAIRO_MIME_TYPE_URI' is not present, but 'CAIRO_MIME_TYPE_JPEG' or 'CAIRO_MIME_TYPE_PNG' is specified, the corresponding data is Base64-encoded and emitted. FILENAME a filename for the SVG output (must be writable), ''#f'' may be used to specify no output. This will generate a SVG surface that may be queried and used as a source, without generating a temporary file. WIDTH-IN-POINTS width of the surface, in points (1 point == 1/72.0 inch) HEIGHT-IN-POINTS height of the surface, in points (1 point == 1/72.0 inch) RET a pointer to the newly created surface. The caller owns the surface and should call 'cairo-surface-destroy' when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use 'cairo-surface-status' to check for this. Since 1.2  File: guile-cairo.info, Node: cairo_matrix_t, Next: Error handling, Prev: SVG Surfaces, Up: Top 22 cairo_matrix_t ***************** Generic matrix operations 22.1 Overview ============= '' is used throughout cairo to convert between different coordinate spaces. A '' holds an affine transformation, such as a scale, rotation, shear, or a combination of these. The transformation of a point ('x','y') is given by: x_new = xx * x + xy * y + x0; y_new = yx * x + yy * y + y0; The current transformation matrix of a '', represented as a '', defines the transformation from user-space coordinates to device-space coordinates. See 'cairo-get-matrix' and 'cairo-set-matrix'. 22.2 Usage ========== -- Function: cairo-matrix-translate (MATRIX '') (TX '') (TY '') Applies a translation by TX, TY to the transformation in MATRIX. The effect of the new transformation is to first translate the coordinates by TX and TY, then apply the original transformation to the coordinates. MATRIX a '' TX amount to translate in the X direction TY amount to translate in the Y direction -- Function: cairo-matrix-invert (MATRIX '') => (RET '') Changes MATRIX to be the inverse of its original value. Not all transformation matrices have inverses; if the matrix collapses points together (it is "degenerate"), then it has no inverse and this function will fail. MATRIX a '' RET If MATRIX has an inverse, modifies MATRIX to be the inverse matrix and returns 'CAIRO_STATUS_SUCCESS'. Otherwise, returns 'CAIRO_STATUS_INVALID_MATRIX'. -- Function: cairo-matrix-multiply (RESULT '') (A '') (B '') Multiplies the affine transformations in A and B together and stores the result in RESULT. The effect of the resulting transformation is to first apply the transformation in A to the coordinates and then apply the transformation in B to the coordinates. It is allowable for RESULT to be identical to either A or B. RESULT a '' in which to store the result A a '' B a '' -- Function: cairo-matrix-transform-distance (MATRIX '') => (DX '') (DY '') Transforms the distance vector (DX,DY) by MATRIX. This is similar to 'cairo-matrix-transform-point' except that the translation components of the transformation are ignored. The calculation of the returned vector is as follows: dx2 = dx1 * a + dy1 * c; dy2 = dx1 * b + dy1 * d; Affine transformations are position invariant, so the same vector always transforms to the same vector. If (X1,Y1) transforms to (X2,Y2) then (X1+DX1,Y1+DY1) will transform to (X1+DX2,Y1+DY2) for all values of X1 and X2. MATRIX a '' DX X component of a distance vector. An in/out parameter DY Y component of a distance vector. An in/out parameter -- Function: cairo-matrix-transform-point (MATRIX '') => (X '') (Y '') Transforms the point (X, Y) by MATRIX.

A status value of 'CAIRO_STATUS_SUCCESS' represents no error and has an integer value of zero. All other status values represent an error. Cairo's error handling is designed to be easy to use and safe. All major cairo objects "retain" an error status internally which can be queried anytime by the users using cairo*_status() calls. In the mean time, it is safe to call all cairo functions normally even if the underlying object is in an error status. This means that no error handling code is required before or after each individual cairo function call. 23.2 Usage ==========  File: guile-cairo.info, Node: Version Information, Next: Types, Prev: Error handling, Up: Top 24 Version Information ********************** Compile-time and run-time version checks. 24.1 Overview ============= Cairo has a three-part version number scheme. In this scheme, we use even vs. odd numbers to distinguish fixed points in the software vs. in-progress development, (such as from git instead of a tar file, or as a "snapshot" tar file as opposed to a "release" tar file). _____ Major. Always 1, until we invent a new scheme. / ___ Minor. Even/Odd = Release/Snapshot (tar files) or Branch/Head (git) | / _ Micro. Even/Odd = Tar-file/git | | / 1.0.0 Here are a few examples of versions that one might see. Releases -------- 1.0.0 - A major release 1.0.2 - A subsequent maintenance release 1.2.0 - Another major release Snapshots --------- 1.1.2 - A snapshot (working toward the 1.2.0 release) In-progress development (eg. from git) -------------------------------------- 1.0.1 - Development on a maintenance branch (toward 1.0.2 release) 1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release) 24.2 Compatibility ================== The API/ABI compatibility guarantees for various versions are as follows. First, let's assume some cairo-using application code that is successfully using the API/ABI "from" one version of cairo. Then let's ask the question whether this same code can be moved "to" the API/ABI of another version of cairo. Moving from a release to any later version (release, snapshot, development) is always guaranteed to provide compatibility. Moving from a snapshot to any later version is not guaranteed to provide compatibility, since snapshots may introduce new API that ends up being removed before the next release. Moving from an in-development version (odd micro component) to any later version is not guaranteed to provide compatibility. In fact, there's not even a guarantee that the code will even continue to work with the same in-development version number. This is because these numbers don't correspond to any fixed state of the software, but rather the many states between snapshots and releases. 24.3 Examining the version ========================== Cairo provides the ability to examine the version at either compile-time or run-time and in both a human-readable form as well as an encoded form suitable for direct comparison. Cairo also provides the macro 'cairo-version-encode' to perform the encoding. Compile-time ------------ CAIRO_VERSION_STRING Human-readable CAIRO_VERSION Encoded, suitable for comparison Run-time -------- cairo_version_string() Human-readable cairo_version() Encoded, suitable for comparison For example, checking that the cairo version is greater than or equal to 1.0.0 could be achieved at compile-time or run-time as follows: ##if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(1, 0, 0) printf ("Compiling with suitable cairo version: %s\n", %CAIRO_VERSION_STRING); ##endif if (cairo_version() >= CAIRO_VERSION_ENCODE(1, 0, 0)) printf ("Running with suitable cairo version: %s\n", cairo_version_string ()); 24.4 Usage ========== -- Function: cairo-version => (RET '') Returns the version of the cairo library encoded in a single integer as per 'CAIRO_VERSION_ENCODE'. The encoding ensures that later versions compare greater than earlier versions. A run-time comparison to check that cairo's version is greater than or equal to version X.Y.Z could be performed as follows: if (cairo_version() >= CAIRO_VERSION_ENCODE(X,Y,Z)) {...} See also 'cairo-version-string' as well as the compile-time equivalents 'CAIRO_VERSION' and 'CAIRO_VERSION_STRING'. RET the encoded version. -- Function: cairo-version-string => (RET '') Returns the version of the cairo library as a human-readable string of the form "X.Y.Z". See also 'cairo-version' as well as the compile-time equivalents 'CAIRO_VERSION_STRING' and 'CAIRO_VERSION'. RET a string containing the version.

You can get the device of a surface using @code{cairo-surface-get-device}. Devices are created using custom functions specific to the rendering system you want to use. See the documentation for the surface types for those functions. An important function that devices fulfill is sharing access to the rendering system between Cairo and your application. If you want to access a device directly that you used to draw to with Cairo, you must first call @code{cairo-device-flush} to ensure that Cairo finishes all operations on the device and resets it to a clean state. Cairo also provides the functions @code{cairo-device-acquire} and @code{cairo-device-release} to synchronize access to the rendering system in a multithreaded environment. This is done internally, but can also be used by applications. Putting this all together, a function that works with devices should look something like this: @example void my_device_modifying_function (cairo_device_t *device) @{ cairo_status_t status; // Ensure the device is properly reset cairo_device_flush (device); // Try to acquire the device status = cairo_device_acquire (device); if (status != CAIRO_STATUS_SUCCESS) @{ printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status)); return; @} // Do the custom operations on the device here. // But do not call any Cairo functions that might acquire devices. // Release the device when done. cairo_device_release (device); @} @end example Please refer to the documentation of each backend for additional usage requirements, guarantees provided, and interactions with existing surface API of the device functions for surfaces of that type. @section Usage @include defuns-cairo-device.xml.texi @c %end of fragment guile-cairo-1.10.0/doc/section-cairo-user-fonts.xml.texi0000664000175000017500000000072413063724072020024 00000000000000 @c %start of fragment @node User Fonts @chapter User Fonts Font support with font data provided by the user @section Overview The user-font feature allows the cairo user to provide drawings for glyphs in a font.

A status value of @samp{CAIRO_STATUS_SUCCESS} represents no error and has an integer value of zero. All other status values represent an error. Cairo's error handling is designed to be easy to use and safe. All major cairo objects @dfn{retain} an error status internally which can be queried anytime by the users using cairo*_status() calls. In the mean time, it is safe to call all cairo functions normally even if the underlying object is in an error status. This means that no error handling code is required before or after each individual cairo function call. @section Usage @include defuns-cairo-status.xml.texi @c %end of fragment guile-cairo-1.10.0/doc/defuns-cairo-font-face.xml.texi0000664000175000017500000000067013063724072017401 00000000000000 @c %start of fragment @deffn Function cairo-font-face-get-type (@var{font-face}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) This function returns the type of the backend used to create a font face.

This means that if you imagine the flow from a pattern to user space (and on to device space), then coordinates in that flow will be transformed by the inverse of the pattern matrix.

These calls provide the result of any drawing to the group as a pattern, (either as an explicit object, or set as the source pattern). This group functionality can be convenient for performing intermediate compositing. One common use of a group is to render objects as opaque within the group, (so that they occlude each other), and then blend the result with translucence onto the destination. Groups can be nested arbitrarily deep by making balanced calls to @code{cairo-push-group}/@code{cairo-pop-group}. Each call pushes/pops the new target group onto/from a stack. The @code{cairo-push-group} function calls @code{cairo-save} so that any changes to the graphics state will not be visible outside the group, (the pop_group functions call @code{cairo-restore}). By default the intermediate group will have a content type of @samp{CAIRO_CONTENT_COLOR_ALPHA}. Other content types can be chosen for the group by using @code{cairo-push-group-with-content} instead.

The behavior of this function is equivalent to the sequence of operations: @example cairo_pattern_t *group = cairo_pop_group (cr); cairo_set_source (cr, group); cairo_pattern_destroy (group); @end example but is more convenient as their is no need for a variable to store the short-lived pointer to the pattern.

As with the other stroke parameters, the current line join style is examined by @code{cairo-stroke}, @code{cairo-stroke-extents}, and @code{cairo-stroke-to-path}, but does not have any effect during path construction.

The line width value specifies the diameter of a pen that is circular in user space, (though device-space pen may be an ellipse in general due to scaling/shear/rotation of the CTM). Note: When the description above refers to user space and CTM it refers to the user space and CTM in effect at the time of the stroking operation, not the user space and CTM in effect at the time of the call to @code{cairo-set-line-width}. The simplest usage makes both of these spaces identical. That is, if there is no change to the CTM between a call to @code{cairo-set-line-width} and the stroking operation, then one can just pass user-space values to @code{cairo-set-line-width} and ignore this note. As with the other stroke parameters, the current line width is examined by @code{cairo-stroke}, @code{cairo-stroke-extents}, and @code{cairo-stroke-to-path}, but does not have any effect during path construction. The default line width value is 2.0. @table @var @item cr a @code{} @item width a line width @end table @end deffn @deffn Function cairo-get-line-width (@var{cr}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) This function returns the current line width value exactly as set by @code{cairo-set-line-width}.

If the current line join style is set to @samp{CAIRO_LINE_JOIN_MITER} (see @code{cairo-set-line-join}), the miter limit is used to determine whether the lines should be joined with a bevel instead of a miter. Cairo divides the length of the miter by the line width. If the result is greater than the miter limit, the style is converted to a bevel. As with the other stroke parameters, the current line miter limit is examined by @code{cairo-stroke}, @code{cairo-stroke-extents}, and @code{cairo-stroke-to-path}, but does not have any effect during path construction. The default miter limit value is 10.0, which will convert joins with interior angles less than 11 degrees to bevels instead of miters. For reference, a miter limit of 2.0 makes the miter cutoff at 60 degrees, and a miter limit of 1.414 makes the cutoff at 90 degrees. A miter limit for a desired angle can be computed as: miter limit = 1/sin(angle/2) @table @var @item cr a cairo context @item limit miter limit to set @end table @end deffn @deffn Function cairo-get-miter-limit (@var{cr}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Gets the current miter limit, as set by @code{cairo-set-miter-limit}. @table @var @item cr a cairo context @item ret the current miter limit. @end table @end deffn @deffn Function cairo-set-operator (@var{cr}@tie{}@code{}) (@var{op}@tie{}@code{}) Sets the compositing operator to be used for all drawing operations.

Curved segments of the path will be subdivided until the maximum deviation between the original path and the polygonal approximation is less than @var{tolerance}. The default value is 0.1. A larger value will give better performance, a smaller value, better appearance. (Reducing the value from the default value of 0.1 is unlikely to improve appearance significantly.) The accuracy of paths within Cairo is limited by the precision of its internal arithmetic, and the prescribed @var{tolerance} is restricted to the smallest representable internal value. @table @var @item cr a @code{} @item tolerance the tolerance, in device units (typically pixels) @end table @end deffn @deffn Function cairo-get-tolerance (@var{cr}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Gets the current tolerance value, as set by @code{cairo-set-tolerance}. @table @var @item cr a cairo context @item ret the current tolerance value. @end table @end deffn @deffn Function cairo-clip (@var{cr}@tie{}@code{}) Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by @code{cairo-fill} and according to the current fill rule (see @code{cairo-set-fill-rule}). After @code{cairo-clip}, the current path will be cleared from the cairo context. The current clip region affects all drawing operations by effectively masking out any changes to the surface that are outside the current clip region. Calling @code{cairo-clip} can only make the clip region smaller, never larger. But the current clip is part of the graphics state, so a temporary restriction of the clip region can be achieved by calling @code{cairo-clip} within a @code{cairo-save}/@code{cairo-restore} pair.

Note that code meant to be reusable should not call @code{cairo-reset-clip} as it will cause results unexpected by higher-level code which calls @code{cairo-clip}.

When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.

You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! guile-cairo-1.10.0/doc/defuns-cairo-image.xml.texi0000664000175000017500000000655413063724072016630 00000000000000 @c %start of fragment @deffn Function cairo-format-stride-for-width (@var{format}@tie{}@code{}) (@var{width}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) This function provides a stride value that will respect all alignment requirements of the accelerated image-rendering code within cairo.

Of course, the generated documentation is not perfect. It still contains many C-isms, which are not relevant to the Scheme programmer. In the end, fixing all erroneous documentation will have to be a human endeavor. For that reason, Guile-Cairo's documentation build allows users to override the generated documentation, simply by adding definitions to the `overrides.texi' file included in the source. Then, the next time the documentation is autogenerated, those overrides will be used instead of the automatically generated docs. How can I help improve Guile-Cairo's documentation? --------------------------------------------------- It's very simple, really. Just find the `deffn' in one of the defuns-cairo*.texi files, copy and paste it into `overrides.texi', then edit to your heart's content. Send a patch to the maintainer and your docs will make everyone's lives better. If it is the "overview" section whose documentation you want to fix, go ahead and submit a patch to the section-foo.texi file or to guile-cairo.texi. The intention is to not regenerate the section-* files. How can I regenerate the documentation? --------------------------------------- The toolchain to regenerate the defuns-*.texi files is a bit bleeding-edge; for that reason, the generated files are included in the Guile-Cairo distribution, and the documentation is normally regenerated by hand. If you want to do so yourself, you will need: * guile-lib > 0.1.4, or from bzr after 28 July 2007; * guile-gnome-platform > 2.15.93, or from bzr after 27 July 2007. (Really all you need is the glib module, which has gtk-doc.scm.) Then you simply type `make generate-defuns' in doc/. What about a tutorial? ---------------------- That would be nice, yes, but for now you will have to look at the C documentation on http://cairographics.org/. guile-cairo-1.10.0/doc/defuns-cairo-svg.xml.texi0000644000175000017500000000362713256407245016345 00000000000000 @c %start of fragment @deffn Function cairo-svg-surface-create (@var{filename}@tie{}@code{}) (@var{width-in-points}@tie{}@code{}) (@var{height-in-points}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Creates a SVG surface of the specified size in points to be written to @var{filename}. The SVG surface backend recognizes the following MIME types for the data attached to a surface (see @code{cairo-surface-set-mime-data}) when it is used as a source pattern for drawing on this surface: @samp{CAIRO_MIME_TYPE_JPEG}, @samp{CAIRO_MIME_TYPE_PNG}, @samp{CAIRO_MIME_TYPE_URI}. If any of them is specified, the SVG backend emits a href with the content of MIME data instead of a surface snapshot (PNG, Base64-encoded) in the corresponding image tag. The unofficial MIME type @samp{CAIRO_MIME_TYPE_URI} is examined first. If present, the URI is emitted as is: assuring the correctness of URI is left to the client code. If @samp{CAIRO_MIME_TYPE_URI} is not present, but @samp{CAIRO_MIME_TYPE_JPEG} or @samp{CAIRO_MIME_TYPE_PNG} is specified, the corresponding data is Base64-encoded and emitted. @table @var @item filename a filename for the SVG output (must be writable), @samp{@code{#f}} may be used to specify no output. This will generate a SVG surface that may be queried and used as a source, without generating a temporary file. @item width-in-points width of the surface, in points (1 point == 1/72.0 inch) @item height-in-points height of the surface, in points (1 point == 1/72.0 inch) @item ret a pointer to the newly created surface. The caller owns the surface and should call @code{cairo-surface-destroy} when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs.

(c) the licenses granted in this Section 2.1(a) and (b) are effective on the date Initial Developer first distributes Original Code under the terms of this License. (d) Notwithstanding Section 2.1(b) above, no patent license is granted: 1) for code that You delete from the Original Code; 2) separate from the Original Code; or 3) for infringements caused by: i) the modification of the Original Code or ii) the combination of the Original Code with other software or devices. 2.2. Contributor Grant. Subject to third party intellectual property claims, each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license (a) under intellectual property rights (other than patent or trademark) Licensable by Contributor, to use, reproduce, modify, display, perform, sublicense and distribute the Modifications created by such Contributor (or portions thereof) either on an unmodified basis, with other Modifications, as Covered Code and/or as part of a Larger Work; and (b) under Patent Claims infringed by the making, using, or selling of Modifications made by that Contributor either alone and/or in combination with its Contributor Version (or portions of such combination), to make, use, sell, offer for sale, have made, and/or otherwise dispose of: 1) Modifications made by that Contributor (or portions thereof); and 2) the combination of Modifications made by that Contributor with its Contributor Version (or portions of such combination). (c) the licenses granted in Sections 2.2(a) and 2.2(b) are effective on the date Contributor first makes Commercial Use of the Covered Code. (d) Notwithstanding Section 2.2(b) above, no patent license is granted: 1) for any code that Contributor has deleted from the Contributor Version; 2) separate from the Contributor Version; 3) for infringements caused by: i) third party modifications of Contributor Version or ii) the combination of Modifications made by that Contributor with other software (except as part of the Contributor Version) or other devices; or 4) under Patent Claims infringed by Covered Code in the absence of Modifications made by that Contributor. 3. Distribution Obligations. 3.1. Application of License. The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5. 3.2. Availability of Source Code. Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party. 3.3. Description of Modifications. You must cause all Covered Code to which You contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code. 3.4. Intellectual Property Matters (a) Third Party Claims. If Contributor has knowledge that a license under a third party's intellectual property rights is required to exercise the rights granted by such Contributor under Sections 2.1 or 2.2, Contributor must include a text file with the Source Code distribution titled "LEGAL" which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If Contributor obtains such knowledge after the Modification is made available as described in Section 3.2, Contributor shall promptly modify the LEGAL file in all copies Contributor makes available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained. (b) Contributor APIs. If Contributor's Modifications include an application programming interface and Contributor has knowledge of patent licenses which are reasonably necessary to implement that API, Contributor must also include this information in the LEGAL file. (c) Representations. Contributor represents that, except as disclosed pursuant to Section 3.4(a) above, Contributor believes that Contributor's Modifications are Contributor's original creation(s) and/or Contributor has sufficient rights to grant the rights conveyed by this License. 3.5. Required Notices. You must duplicate the notice in Exhibit A in each file of the Source Code. If it is not possible to put such notice in a particular Source Code file due to its structure, then You must include such notice in a location (such as a relevant directory) where a user would be likely to look for such a notice. If You created one or more Modification(s) You may add your name as a Contributor to the notice described in Exhibit A. You must also duplicate this License in any documentation for the Source Code where You describe recipients' rights or ownership rights relating to Covered Code. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of warranty, support, indemnity or liability terms You offer. 3.6. Distribution of Executable Versions. You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code or ownership rights under a license of Your choice, which may contain terms different from this License, provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer. 3.7. Larger Works. You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code. 4. Inability to Comply Due to Statute or Regulation. If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Application of this License. This License applies to code to which the Initial Developer has attached the notice in Exhibit A and to related Covered Code. 6. Versions of the License. 6.1. New Versions. Netscape Communications Corporation ("Netscape") may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number. 6.2. Effect of New Versions. Once Covered Code has been published under a particular version of the License, You may always continue to use it under the terms of that version. You may also choose to use such Covered Code under the terms of any subsequent version of the License published by Netscape. No one other than Netscape has the right to modify the terms applicable to Covered Code created under this License. 6.3. Derivative Works. If You create or use a modified version of this License (which you may only do in order to apply it to code which is not already Covered Code governed by this License), You must (a) rename Your license so that the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape", "MPL", "NPL" or any confusingly similar phrase do not appear in your license (except to note that your license differs from this License) and (b) otherwise make it clear that Your version of the license contains terms which differ from the Mozilla Public License and Netscape Public License. (Filling in the name of the Initial Developer, Original Code or Contributor in the notice described in Exhibit A shall not of themselves be deemed to be modifications of this License.) 7. DISCLAIMER OF WARRANTY. COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. 8. TERMINATION. 8.1. This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive. 8.2. If You initiate litigation by asserting a patent infringement claim (excluding declatory judgment actions) against Initial Developer or a Contributor (the Initial Developer or Contributor against whom You file such action is referred to as "Participant") alleging that: (a) such Participant's Contributor Version directly or indirectly infringes any patent, then any and all rights granted by such Participant to You under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice from Participant terminate prospectively, unless if within 60 days after receipt of notice You either: (i) agree in writing to pay Participant a mutually agreeable reasonable royalty for Your past and future use of Modifications made by such Participant, or (ii) withdraw Your litigation claim with respect to the Contributor Version against such Participant. If within 60 days of notice, a reasonable royalty and payment arrangement are not mutually agreed upon in writing by the parties or the litigation claim is not withdrawn, the rights granted by Participant to You under Sections 2.1 and/or 2.2 automatically terminate at the expiration of the 60 day notice period specified above. (b) any software, hardware, or device, other than such Participant's Contributor Version, directly or indirectly infringes any patent, then any rights granted to You by such Participant under Sections 2.1(b) and 2.2(b) are revoked effective as of the date You first made, used, sold, distributed, or had made, Modifications made by that Participant. 8.3. If You assert a patent infringement claim against Participant alleging that such Participant's Contributor Version directly or indirectly infringes any patent where such claim is resolved (such as by license or settlement) prior to the initiation of patent infringement litigation, then the reasonable value of the licenses granted by such Participant under Sections 2.1 or 2.2 shall be taken into account in determining the amount or value of any payment or license. 8.4. In the event of termination under Sections 8.1 or 8.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or any distributor hereunder prior to termination shall survive termination. 9. LIMITATION OF LIABILITY. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. 10. U.S. GOVERNMENT END USERS. The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Code with only those rights set forth herein. 11. MISCELLANEOUS. This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by California law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. With respect to disputes in which at least one party is a citizen of, or an entity chartered or registered to do business in the United States of America, any litigation relating to this License shall be subject to the jurisdiction of the Federal Courts of the Northern District of California, with venue lying in Santa Clara County, California, with the losing party responsible for costs, including without limitation, court costs and reasonable attorneys' fees and expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License. 12. RESPONSIBILITY FOR CLAIMS. As between Initial Developer and the Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License and You agree to work with Initial Developer and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability. 13. MULTIPLE-LICENSED CODE. Initial Developer may designate portions of the Covered Code as "Multiple-Licensed". "Multiple-Licensed" means that the Initial Developer permits you to utilize portions of the Covered Code under Your choice of the NPL or the alternative licenses, if any, specified by the Initial Developer in the file described in Exhibit A.

The recording surface can then be "replayed" against any target surface by using it as a source surface. If you want to replay a surface so that the results in target will be identical to the results that would have been obtained if the original operations applied to the recording surface had instead been applied to the target surface, you can use code like this: @example cairo_t *cr; cr = cairo_create (target); cairo_set_source_surface (cr, recording_surface, 0.0, 0.0); cairo_paint (cr); cairo_destroy (cr); @end example A recording surface is logically unbounded, i.e. it has no implicit constraint on the size of the drawing surface. However, in practice this is rarely useful as you wish to replay against a particular target surface with known bounds. For this case, it is more efficient to specify the target extents to the recording surface upon creation. The recording phase of the recording surface is careful to snapshot all necessary objects (paths, patterns, etc.), in order to achieve accurate replay. The efficiency of the recording surface could be improved by improving the implementation of snapshot for the various objects. For example, it would be nice to have a copy-on-write implementation for _cairo_surface_snapshot. @section Usage @include defuns-cairo-recording.xml.texi @c %end of fragment guile-cairo-1.10.0/doc/defuns-cairo-ps.xml.texi0000644000175000017500000002005713256407245016164 00000000000000 @c %start of fragment @deffn Function cairo-ps-surface-create (@var{filename}@tie{}@code{}) (@var{width-in-points}@tie{}@code{}) (@var{height-in-points}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Creates a PostScript surface of the specified size in points to be written to @var{filename}. See @code{cairo-ps-surface-create-for-stream} for a more flexible mechanism for handling the PostScript output than simply writing it to a named file. Note that the size of individual pages of the PostScript output can vary. See @code{cairo-ps-surface-set-size}. @table @var @item filename a filename for the PS output (must be writable), @samp{@code{#f}} may be used to specify no output. This will generate a PS surface that may be queried and used as a source, without generating a temporary file. @item width-in-points width of the surface, in points (1 point == 1/72.0 inch) @item height-in-points height of the surface, in points (1 point == 1/72.0 inch) @item ret a pointer to the newly created surface. The caller owns the surface and should call @code{cairo-surface-destroy} when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use @code{cairo-surface-status} to check for this. @end table Since 1.2 @end deffn @deffn Function cairo-ps-surface-restrict-to-level (@var{surface}@tie{}@code{}) (@var{level}@tie{}@code{}) Restricts the generated PostSript file to @var{level}. See @code{cairo-ps-get-levels} for a list of available level values that can be used here. This function should only be called before any drawing operations have been performed on the given surface. The simplest way to do this is to call this function immediately after creating the surface. @table @var @item surface a PostScript @code{} @item level PostScript level @end table Since 1.6 @end deffn @deffn Function cairo-ps-get-levels @result{}@tie{} (@var{levels}@tie{}@code{}) (@var{num-levels}@tie{}@code{}) Used to retrieve the list of supported levels.

This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface.

This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface or immediately after completing a page with either @code{cairo-show-page} or @code{cairo-copy-page}. @table @var @item surface a PostScript @code{} @item width-in-points new surface width, in points (1 point == 1/72.0 inch) @item height-in-points new surface height, in points (1 point == 1/72.0 inch) @end table Since 1.2 @end deffn @deffn Function cairo-ps-surface-dsc-comment (@var{surface}@tie{}@code{}) (@var{comment}@tie{}@code{}) Emit a comment into the PostScript output for the given surface. The comment is expected to conform to the PostScript Language Document Structuring Conventions (DSC). Please see that manual for details on the available comments and their meanings. In particular, the %@samp{IncludeFeature} comment allows a device-independent means of controlling printer device features. So the PostScript Printer Description Files Specification will also be a useful reference. The comment string must begin with a percent character (%) and the total length of the string (including any initial percent characters) must not exceed 255 characters. Violating either of these conditions will place @var{surface} into an error state. But beyond these two conditions, this function will not enforce conformance of the comment with any particular specification. The comment string should not have a trailing newline. The DSC specifies different sections in which particular comments can appear. This function provides for comments to be emitted within three sections: the header, the Setup section, and the PageSetup section. Comments appearing in the first two sections apply to the entire document while comments in the BeginPageSetup section apply only to a single page. For comments to appear in the header section, this function should be called after the surface is created, but before a call to @code{cairo-ps-surface-begin-setup}. For comments to appear in the Setup section, this function should be called after a call to @code{cairo-ps-surface-begin-setup} but before a call to @code{cairo-ps-surface-begin-page-setup}. For comments to appear in the PageSetup section, this function should be called after a call to @code{cairo-ps-surface-begin-page-setup}. Note that it is only necessary to call @code{cairo-ps-surface-begin-page-setup} for the first page of any surface. After a call to @code{cairo-show-page} or @code{cairo-copy-page} comments are unambiguously directed to the PageSetup section of the current page. But it doesn't hurt to call this function at the beginning of every page as that consistency may make the calling code simpler. As a final note, cairo automatically generates several comments on its own. As such, applications must not manually generate any of the following comments: Header section: %!PS-Adobe-3.0, %@samp{Creator}, %@samp{CreationDate}, %@samp{Pages}, %@samp{BoundingBox}, %@samp{DocumentData}, %@samp{LanguageLevel}, %@samp{EndComments}. Setup section: %@samp{BeginSetup}, %@samp{EndSetup} PageSetup section: %@samp{BeginPageSetup}, %@samp{PageBoundingBox}, %@samp{EndPageSetup}. Other sections: %@samp{BeginProlog}, %@samp{EndProlog}, %@samp{Page}, %@samp{Trailer}, %@samp{EOF} Here is an example sequence showing how this function might be used: @example cairo_surface_t *surface = cairo_ps_surface_create (filename, width, height); ... cairo_ps_surface_dsc_comment (surface, "%%Title: My excellent document"); cairo_ps_surface_dsc_comment (surface, "%%Copyright: Copyright (C) 2006 Cairo Lover") ... cairo_ps_surface_dsc_begin_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor White"); ... cairo_ps_surface_dsc_begin_page_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A3"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *InputSlot LargeCapacity"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaType Glossy"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor Blue"); ... draw to first page here .. cairo_show_page (cr); ... cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A5"); ... @end example @table @var @item surface a PostScript @code{} @item comment a comment string to be emitted into the PostScript output @end table Since 1.2 @end deffn @c %end of fragment guile-cairo-1.10.0/doc/defuns-cairo-quartz-fonts.xml.texi0000664000175000017500000000005513063724072020211 00000000000000 @c %start of fragment @c %end of fragment guile-cairo-1.10.0/doc/defuns-cairo-text.xml.texi0000664000175000017500000003736413063724072016535 00000000000000 @c %start of fragment @deffn Function cairo-select-font-face (@var{cr}@tie{}@code{}) (@var{family}@tie{}@code{}) (@var{slant}@tie{}@code{}) (@var{weight}@tie{}@code{}) Note: The @code{cairo-select-font-face} function call is part of what the cairo designers call the "toy" text API.

Selects a family and style of font from a simplified description as a family name, slant and weight. Cairo provides no operation to list available family names on the system (this is a "toy", remember), but the standard CSS2 generic family names, ("serif", "sans-serif", "cursive", "fantasy", "monospace"), are likely to work as expected. If @var{family} starts with the string "@var{cairo}:", or if no native font backends are compiled in, cairo will use an internal font family. The internal font family recognizes many modifiers in the @var{family} string, most notably, it recognizes the string "monospace". That is, the family name "@var{cairo}:monospace" will use the monospace version of the internal font family. For "real" font selection, see the font-backend-specific font_face_create functions for the font backend you are using. (For example, if you are using the freetype-based cairo-ft font backend, see @code{cairo-ft-font-face-create-for-ft-face} or @code{cairo-ft-font-face-create-for-pattern}.) The resulting font face could then be used with @code{cairo-scaled-font-create} and @code{cairo-set-scaled-font}. Similarly, when using the "real" font support, you can call directly into the underlying font system, (such as fontconfig or freetype), for operations such as listing available fonts, etc. It is expected that most applications will need to use a more comprehensive font handling and text layout library, (for example, pango), in conjunction with cairo. If text is drawn without a call to @code{cairo-select-font-face}, (nor @code{cairo-set-font-face} nor @code{cairo-set-scaled-font}), the default family is platform-specific, but is essentially "sans-serif". Default slant is @samp{CAIRO_FONT_SLANT_NORMAL}, and default weight is @samp{CAIRO_FONT_WEIGHT_NORMAL}. This function is equivalent to a call to @code{cairo-toy-font-face-create} followed by @code{cairo-set-font-face}. @table @var @item cr a @code{} @item family a font family name, encoded in UTF-8 @item slant the slant for the font @item weight the weight for the font @end table @end deffn @deffn Function cairo-set-font-size (@var{cr}@tie{}@code{}) (@var{size}@tie{}@code{}) Sets the current font matrix to a scale by a factor of @var{size}, replacing any font matrix previously set with @code{cairo-set-font-size} or @code{cairo-set-font-matrix}. This results in a font size of @var{size} user space units. (More precisely, this matrix will result in the font's em-square being a @var{size} by @var{size} square in user space.) If text is drawn without a call to @code{cairo-set-font-size}, (nor @code{cairo-set-font-matrix} nor @code{cairo-set-scaled-font}), the default font size is 10.0. @table @var @item cr a @code{} @item size the new font size, in user space units @end table @end deffn @deffn Function cairo-set-font-matrix (@var{cr}@tie{}@code{}) (@var{matrix}@tie{}@code{}) Sets the current font matrix to @var{matrix}. The font matrix gives a transformation from the design space of the font (in this space, the em-square is 1 unit by 1 unit) to user space. Normally, a simple scale is used (see @code{cairo-set-font-size}), but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes @table @var @item cr a @code{} @item matrix a @code{} describing a transform to be applied to the current font. @end table @end deffn @deffn Function cairo-get-font-matrix (@var{cr}@tie{}@code{}) (@var{matrix}@tie{}@code{}) Stores the current font matrix into @var{matrix}.

Rendering options are derived by merging these options with the options derived from underlying surface; if the value in @var{options} has a default value (like @samp{CAIRO_ANTIALIAS_DEFAULT}), then the value from the surface is used. @table @var @item cr a @code{} @item options font options to use @end table @end deffn @deffn Function cairo-get-font-options (@var{cr}@tie{}@code{}) (@var{options}@tie{}@code{}) Retrieves font rendering options set via @code{}. Note that the returned options do not include any options derived from the underlying surface; they are literally the options passed to @code{cairo-set-font-options}. @table @var @item cr a @code{} @item options a @code{} object into which to store the retrieved options. All existing values are overwritten @end table @end deffn @deffn Function cairo-set-font-face (@var{cr}@tie{}@code{}) (@var{font-face}@tie{}@code{}) Replaces the current @code{} object in the @code{} with @var{font-face}.

This object is owned by cairo. To keep a reference to it, you must call @code{cairo-font-face-reference}. This function never returns @samp{@code{#f}}. If memory cannot be allocated, a special "nil" @code{} object will be returned on which @code{cairo-font-face-status} returns @samp{CAIRO_STATUS_NO_MEMORY}. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling @code{cairo-set-font-face} with a nil font will trigger an error that will shutdown the @code{} object). @end table @end deffn @deffn Function cairo-set-scaled-font (@var{cr}@tie{}@code{}) (@var{scaled-font}@tie{}@code{}) Replaces the current font face, font matrix, and font options in the @code{} with those of the @code{}. Except for some translation, the current CTM of the @code{} should be the same as that of the @code{}, which can be accessed using @code{cairo-scaled-font-get-ctm}. @table @var @item cr a @code{} @item scaled-font a @code{} @end table Since 1.2 @end deffn @deffn Function cairo-get-scaled-font (@var{cr}@tie{}@code{}) @result{}@tie{} (@var{ret}@tie{}@code{}) Gets the current scaled font for a @code{}. @table @var @item cr a @code{} @item ret the current scaled font. This object is owned by cairo. To keep a reference to it, you must call @code{cairo-scaled-font-reference}. This function never returns @samp{@code{#f}}.

This function first computes a set of glyphs for the string of text. The first glyph is placed so that its origin is at the current point. The origin of each subsequent glyph is offset from that of the previous glyph by the advance values of the previous glyph. After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for easy display of a single logical string with multiple calls to @code{cairo-show-text}. Note: The @code{cairo-show-text} function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See @code{cairo-show-glyphs} for the "real" text display API in cairo. @table @var @item cr a cairo context @item utf8 a NUL-terminated string of text encoded in UTF-8, or @samp{@code{#f}} @end table @end deffn @deffn Function cairo-show-glyphs (@var{cr}@tie{}@code{}) (@var{glyphs}@tie{}@code{}) (@var{num-glyphs}@tie{}@code{}) A drawing operator that generates the shape from an array of glyphs, rendered according to the current font face, font size (font matrix), and font options. @table @var @item cr a cairo context @item glyphs array of glyphs to show @item num-glyphs number of glyphs to show @end table @end deffn @deffn Function cairo-show-text-glyphs (@var{cr}@tie{}@code{}) (@var{utf8}@tie{}@code{}) (@var{utf8-len}@tie{}@code{}) (@var{glyphs}@tie{}@code{}) (@var{num-glyphs}@tie{}@code{}) (@var{clusters}@tie{}@code{}) (@var{num-clusters}@tie{}@code{}) (@var{cluster-flags}@tie{}@code{}) This operation has rendering effects similar to @code{cairo-show-glyphs} but, if the target surface supports it, uses the provided text and cluster mapping to embed the text for the glyphs shown in the output. If the target does not support the extended attributes, this function acts like the basic @code{cairo-show-glyphs} as if it had been passed @var{glyphs} and @var{num-glyphs}. The mapping between @var{utf8} and @var{glyphs} is provided by an array of @dfn{clusters}. Each cluster covers a number of text bytes and glyphs, and neighboring clusters cover neighboring areas of @var{utf8} and @var{glyphs}. The clusters should collectively cover @var{utf8} and @var{glyphs} in entirety. The first cluster always covers bytes from the beginning of @var{utf8}. If @var{cluster-flags} do not have the @samp{CAIRO_TEXT_CLUSTER_FLAG_BACKWARD} set, the first cluster also covers the beginning of @var{glyphs}, otherwise it covers the end of the @var{glyphs} array and following clusters move backward. See @code{} for constraints on valid clusters. @table @var @item cr a cairo context @item utf8 a string of text encoded in UTF-8 @item utf8-len length of @var{utf8} in bytes, or -1 if it is NUL-terminated @item glyphs array of glyphs to show @item num-glyphs number of glyphs to show @item clusters array of cluster mapping information @item num-clusters number of clusters in the mapping @item cluster-flags cluster mapping flags @end table Since 1.8 @end deffn @deffn Function cairo-font-extents (@var{cr}@tie{}@code{}) (@var{extents}@tie{}@code{}) Gets the font extents for the currently selected font. @table @var @item cr a @code{} @item extents a @code{} object into which the results will be stored. @end table @end deffn @deffn Function cairo-text-extents (@var{cr}@tie{}@code{}) (@var{utf8}@tie{}@code{}) (@var{extents}@tie{}@code{}) Gets the extents for a string of text. The extents describe a user-space rectangle that encloses the "inked" portion of the text, (as it would be drawn by @code{cairo-show-text}). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by @code{cairo-show-text}. Note that whitespace characters do not directly contribute to the size of the rectangle (extents.width and extents.height). They do contribute indirectly by changing the position of non-whitespace characters. In particular, trailing whitespace characters are likely to not affect the size of the rectangle, though they will affect the x_advance and y_advance values. @table @var @item cr a @code{} @item utf8 a NUL-terminated string of text encoded in UTF-8, or @samp{@code{#f}} @item extents a @code{} object into which the results will be stored @end table @end deffn @deffn Function cairo-glyph-extents (@var{cr}@tie{}@code{}) (@var{glyphs}@tie{}@code{}) (@var{num-glyphs}@tie{}@code{}) (@var{extents}@tie{}@code{}) Gets the extents for an array of glyphs.

These font faces are used in implementation of the the @code{} "toy" font API. If @var{family} is the zero-length string "", the platform-specific default family is assumed. The default family then can be queried using @code{cairo-toy-font-face-get-family}. The @code{cairo-select-font-face} function uses this to create font faces.

This documentation was automatically generated. cairo-font-options-merge - Function: cairo-font-options-merge (OPTIONS `')(OTHER `') Merges non-default options from OTHER into OPTIONS, replacing existing values. This operation can be thought of as somewhat similar to compositing OTHER onto OPTIONS with the operation of `CAIRO_OPERATION_OVER'. options a `' other another `' This documentation was automatically generated. cairo-font-options-hash - Function: cairo-font-options-hash (OPTIONS `') ==>(RET `') Compute a hash for the font options object; this value will be useful when storing an object containing a cairo_font_options_t in a hash table. options a `' ret the hash value for the font options object. The return value can be cast to a 32-bit type if a 32-bit hash value is needed. This documentation was automatically generated. cairo-font-options-set-antialias - Function: cairo-font-options-set-antialias (OPTIONS `')(ANTIALIAS `') Sets the antialiasing mode for the font options object. This specifies the type of antialiasing to do when rendering text. options a `' antialias the new antialiasing mode This documentation was automatically generated. cairo-font-options-get-antialias - Function: cairo-font-options-get-antialias (OPTIONS `') ==>(RET `') Gets the antialiasing mode for the font options object. options a `' ret the antialiasing mode This documentation was automatically generated. cairo-font-options-set-hint-style - Function: cairo-font-options-set-hint-style (OPTIONS `')(HINT-STYLE `') Sets the hint style for font outlines for the font options object. This controls whether to fit font outlines to the pixel grid, and if so, whether to optimize for fidelity or contrast. See the documentation for `' for full details. options a `' hint-style the new hint style This documentation was automatically generated. cairo-font-options-get-hint-style - Function: cairo-font-options-get-hint-style (OPTIONS `') ==>(RET `') Gets the hint style for font outlines for the font options object.

This controls whether metrics are quantized to integer values in device units. See the documentation for `' for full details. options a `' hint-metrics the new metrics hinting mode This documentation was automatically generated. cairo-font-face-get-type - Function: cairo-font-face-get-type (FONT-FACE `') ==>(RET `') This function returns the type of the backend used to create a font face. See `' for available types. font-face a font face ret The type of FONT-FACE. Since 1.2 This documentation was automatically generated. cairo-image-surface-create - Function: cairo-image-surface-create (FORMAT `')(WIDTH `')(HEIGHT `') ==>(RET `') Creates an image surface of the specified format and dimensions. Initially the surface contents are all 0. (Specifically, within each pixel, each color or alpha channel belonging to format will be 0. The contents of bits within a pixel, but not belonging to the given format are undefined). format format of pixels in the surface to create width width of the surface, in pixels height height of the surface, in pixels ret a pointer to the newly created surface. The caller owns the surface and should call cairo_surface_destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use `cairo-surface-status' to check for this. This documentation was automatically generated. cairo-image-surface-get-format - Function: cairo-image-surface-get-format (SURFACE `') ==>(RET `') Get the format of the surface. surface a `' ret the format of the surface Since 1.2 This documentation was automatically generated. cairo-image-surface-get-width - Function: cairo-image-surface-get-width (SURFACE `') ==>(RET `') Get the width of the image surface in pixels. surface a `' ret the width of the surface in pixels. This documentation was automatically generated. cairo-matrix-translate - Function: cairo-matrix-translate (MATRIX `')(TX `')(TY `') Applies a translation by TX, TY to the transformation in MATRIX. The effect of the new transformation is to first translate the coordinates by TX and TY, then apply the original transformation to the coordinates. matrix a cairo_matrix_t tx amount to translate in the X direction ty amount to translate in the Y direction This documentation was automatically generated. cairo-matrix-invert - Function: cairo-matrix-invert (MATRIX `') ==>(RET `') Changes MATRIX to be the inverse of it's original value. Not all transformation matrices have inverses; if the matrix collapses points together (it is "degenerate"), then it has no inverse and this function will fail. Returns: If MATRIX has an inverse, modifies MATRIX to be the inverse matrix and returns `CAIRO_STATUS_SUCCESS'. Otherwise, matrix a `' ret `CAIRO_STATUS_INVALID_MATRIX'. This documentation was automatically generated. cairo-matrix-multiply - Function: cairo-matrix-multiply (RESULT `')(A `')(B `') Multiplies the affine transformations in A and B together and stores the result in RESULT. The effect of the resulting transformation is to first apply the transformation in A to the coordinates and then apply the transformation in B to the coordinates. It is allowable for RESULT to be identical to either A or B. result a `' in which to store the result a a `' b a `' This documentation was automatically generated. cairo-matrix-transform-distance - Function: cairo-matrix-transform-distance (MATRIX `') ==>(DX `')(DY `') Transforms the distance vector (DX,DY) by MATRIX. This is similar to `cairo-matrix-transform-point' except that the translation components of the transformation are ignored. The calculation of the returned vector is as follows: dx2 = dx1 * a + dy1 * c; dy2 = dx1 * b + dy1 * d; Affine transformations are position invariant, so the same vector always transforms to the same vector. If (X1,Y1) transforms to (X2,Y2) then (X1+DX1,Y1+DY1) will transform to (X1+DX2,Y1+DY2) for all values of X1 and X2. matrix a `' dx X component of a distance vector. An in/out parameter dy Y component of a distance vector. An in/out parameter This documentation was automatically generated. cairo-matrix-transform-point - Function: cairo-matrix-transform-point (MATRIX `') ==>(X `')(Y `') Transforms the point (X, Y) by MATRIX. matrix a `' x X position.

An in/out parameter This documentation was automatically generated. cairo-copy-path - Function: cairo-copy-path (CR `') ==>(RET `') Creates a copy of the current path and returns it to the user as a `'. See `' for hints on how to iterate over the returned data structure. This function will always return a valid pointer, but the result will have no data (`data==NULL' and `num_data==0'), if either of the following conditions hold: If ther1. s insufficient memory to copy the path. In this case `path->status' will be set to `CAIRO_STATUS_NO_MEMORY'.If CR i2. lready in an error state. In this case `path->status' will contain the same status that would be returned by `cairo-status'. In either case, `path->status' will be set to `CAIRO_STATUS_NO_MEMORY' (regardless of what the error status in CR might have been). cr a cairo context ret the copy of the current path. The caller owns the returned object and should call `cairo-path-destroy' when finished with it. This documentation was automatically generated. cairo-copy-path-flat - Function: cairo-copy-path-flat (CR `') ==>(RET `') Gets a flattened copy of the current path and returns it to the user as a `'. See `' for hints on how to iterate over the returned data structure. This function is like `cairo-copy-path' except that any curves in the path will be approximated with piecewise-linear approximations, (accurate to within the current tolerance value). That is, the result is guaranteed to not have any elements of type `CAIRO_PATH_CURVE_TO' which will instead be replaced by a series of `CAIRO_PATH_LINE_TO' elements. This function will always return a valid pointer, but the result will have no data (`data==NULL' and `num_data==0'), if either of the following conditions hold: If ther1. s insufficient memory to copy the path. In this case `path->status' will be set to `CAIRO_STATUS_NO_MEMORY'.If CR i2. lready in an error state. In this case `path->status' will contain the same status that would be returned by `cairo-status'. cr a cairo context ret the copy of the current path. The caller owns the returned object and should call `cairo-path-destroy' when finished with it. This documentation was automatically generated. cairo-append-path - Function: cairo-append-path (CR `')(PATH `') Append the PATH onto the current path. The PATH may be either the return value from one of `cairo-copy-path' or `cairo-copy-path-flat' or it may be constructed manually. See `' for details on how the path data structure should be initialized, and note that `path->status' must be initialized to `CAIRO_STATUS_SUCCESS'. cr a cairo context path path to be appended This documentation was automatically generated. cairo-get-current-point - Function: cairo-get-current-point (CR `') ==>(X `')(Y `') Gets the current point of the current path, which is conceptually the final point reached by the path so far. The current point is returned in the user-space coordinate system. If there is no defined current point then X and Y will both be set to 0.0. Most path construction functions alter the current point. See the following for details on how they affect the current point: `cairo-new-path', `cairo-move-to', `cairo-line-to', `cairo-curve-to', `cairo-arc', `cairo-rel-move-to', `cairo-rel-line-to', `cairo-rel-curve-to', `cairo-arc', `cairo-text-path', `cairo-stroke-to-path' cr a cairo context x return value for X coordinate of the current point y return value for Y coordinate of the current point This documentation was automatically generated. cairo-new-path - Function: cairo-new-path (CR `') Clears the current path. After this call there will be no path and no current point. cr a cairo context This documentation was automatically generated. cairo-new-sub-path - Function: cairo-new-sub-path (CR `') Begin a new sub-path. Note that the existing path is not affected. After this call there will be no current point. In many cases, this call is not needed since new sub-paths are frequently started with `cairo-move-to'. A call to `cairo-new-sub-path' is particularly useful when beginning a new sub-path with one of the `cairo-arc' calls. This makes things easier as it is no longer necessary to manually compute the arc's initial coordinates for a call to `cairo-move-to'. cr a cairo context Since 1.2 This documentation was automatically generated. cairo-close-path - Function: cairo-close-path (CR `') Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to `cairo-move-to'), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path. The behavior of `cairo-close-path' is distinct from simply calling `cairo-line-to' with the equivalent coordinate in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead, there is a line join connecting the final and initial segments of the sub-path. If there is no current point before the call to cairo_close_path, this function will have no effect. Note: As of cairo version 1.2.4 any call to cairo_close_path will place an explicit MOVE_TO element into the path immediately after the CLOSE_PATH element, (which can be seen in `cairo-copy-path' for example). This can simplify path processing in some cases as it may not be necessary to save the "last move_to point" during processing as the MOVE_TO immediately after the CLOSE_PATH will provide that point. cr a cairo context This documentation was automatically generated. cairo-arc - Function: cairo-arc (CR `')(XC `')(YC `')(RADIUS `')(ANGLE1 `')(ANGLE2 `') Adds a circular arc of the given RADIUS to the current path. The arc is centered at (XC, YC), begins at ANGLE1 and proceeds in the direction of increasing angles to end at ANGLE2. If ANGLE2 is less than ANGLE1 it will be progressively increased by 2*M_PI until it is greater than ANGLE1. If there is a current point, an initial line segment will be added to the path to connect the current point to the beginning of the arc. Angles are measured in radians. An angle of 0.0 is in the direction of the positive X axis (in user space). An angle of `M_PI'/2.0 radians (90 degrees) is in the direction of the positive Y axis (in user space). Angles increase in the direction from the positive X axis toward the positive Y axis. So with the default transformation matrix, angles increase in a clockwise direction. (To convert from degrees to radians, use `degrees * (M_PI / 180.)'.) This function gives the arc in the direction of increasing angles; see `cairo-arc-negative' to get the arc in the direction of decreasing angles. The arc is circular in user space. To achieve an elliptical arc, you can scale the current transformation matrix by different amounts in the X and Y directions. For example, to draw an ellipse in the box given by X, Y, WIDTH, HEIGHT: cairo_save (cr); cairo_translate (cr, x + width / 2., y + height / 2.); cairo_scale (cr, width / 2., height / 2.); cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI); cairo_restore (cr); cr a cairo context xc X position of the center of the arc yc Y position of the center of the arc radius the radius of the arc angle1 the start angle, in radians angle2 the end angle, in radians This documentation was automatically generated. cairo-arc-negative - Function: cairo-arc-negative (CR `')(XC `')(YC `')(RADIUS `')(ANGLE1 `')(ANGLE2 `') Adds a circular arc of the given RADIUS to the current path. The arc is centered at (XC, YC), begins at ANGLE1 and proceeds in the direction of decreasing angles to end at ANGLE2. If ANGLE2 is greater than ANGLE1 it will be progressively decreased by 2*M_PI until it is less than ANGLE1. See `cairo-arc' for more details. This function differs only in the direction of the arc between the two angles. cr a cairo context xc X position of the center of the arc yc Y position of the center of the arc radius the radius of the arc angle1 the start angle, in radians angle2 the end angle, in radians This documentation was automatically generated. cairo-curve-to - Function: cairo-curve-to (CR `')(X1 `')(Y1 `')(X2 `')(Y2 `')(X3 `')(Y3 `') Adds a cubic Bézier spline to the path from the current point to position (X3, Y3) in user-space coordinates, using (X1, Y1) and (X2, Y2) as the control points. After this call the current point will be (X3, Y3). If there is no current point before the call to `cairo-curve-to' this function will behave as if preceded by a call to cairo_move_to (CR, X1, Y1). cr a cairo context x1 the X coordinate of the first control point y1 the Y coordinate of the first control point x2 the X coordinate of the second control point y2 the Y coordinate of the second control point x3 the X coordinate of the end of the curve y3 the Y coordinate of the end of the curve This documentation was automatically generated. cairo-line-to - Function: cairo-line-to (CR `')(X `')(Y `') Adds a line to the path from the current point to position (X, Y) in user-space coordinates. After this call the current point will be (X, Y). If there is no current point before the call to `cairo-line-to' this function will behave as cairo_move_to (CR, X, Y). cr a cairo context x the X coordinate of the end of the new line y the Y coordinate of the end of the new line This documentation was automatically generated. cairo-move-to - Function: cairo-move-to (CR `')(X `')(Y `') Begin a new sub-path. After this call the current point will be (X, Y). cr a cairo context x the X coordinate of the new position y the Y coordinate of the new position This documentation was automatically generated. cairo-rectangle - Function: cairo-rectangle (CR `')(X `')(Y `')(WIDTH `')(HEIGHT `') Adds a closed sub-path rectangle of the given size to the current path at position (X, Y) in user-space coordinates. This function is logically equivalent to: cairo_move_to (cr, x, y); cairo_rel_line_to (cr, width, 0); cairo_rel_line_to (cr, 0, height); cairo_rel_line_to (cr, -width, 0); cairo_close_path (cr); cr a cairo context x the X coordinate of the top left corner of the rectangle y the Y coordinate to the top left corner of the rectangle width the width of the rectangle height the height of the rectangle This documentation was automatically generated. cairo-glyph-path - Function: cairo-glyph-path (CR `')(GLYPHS `')(NUM-GLYPHS `') Adds closed paths for the glyphs to the current path. The generated path if filled, achieves an effect similar to that of `cairo-show-glyphs'. cr a cairo context glyphs array of glyphs to show num-glyphs number of glyphs to show This documentation was automatically generated. cairo-text-path - Function: cairo-text-path (CR `')(UTF8 `') Adds closed paths for text to the current path. The generated path if filled, achieves an effect similar to that of `cairo-show-text'. Text conversion and positioning is done similar to `cairo-show-text'. Like `cairo-show-text', After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for chaining multiple calls to to `cairo-text-path' without having to set current point in between. NOTE: The `cairo-text-path' function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See `cairo-glyph-path' for the "real" text path API in cairo. cr a cairo context utf8 a string of text encoded in UTF-8 This documentation was automatically generated. cairo-rel-curve-to - Function: cairo-rel-curve-to (CR `')(DX1 `')(DY1 `')(DX2 `')(DY2 `')(DX3 `')(DY3 `') Relative-coordinate version of `cairo-curve-to'. All offsets are relative to the current point. Adds a cubic Bézier spline to the path from the current point to a point offset from the current point by (DX3, DY3), using points offset by (DX1, DY1) and (DX2, DY2) as the control points. After this call the current point will be offset by (DX3, DY3). Given a current point of (x, y), cairo_rel_curve_to (CR, DX1, DY1, DX2, DY2, DX3, DY3) is logically equivalent to cairo_curve_to (CR, x + DX1, y + DY1, x + DX2, y + DY2, x + DX3, y + DY3). It is an error to call this function with no current point. Doing so will cause CR to shutdown with a status of CAIRO_STATUS_NO_CURRENT_POINT. cr a cairo context dx1 the X offset to the first control point dy1 the Y offset to the first control point dx2 the X offset to the second control point dy2 the Y offset to the second control point dx3 the X offset to the end of the curve dy3 the Y offset to the end of the curve This documentation was automatically generated. cairo-rel-line-to - Function: cairo-rel-line-to (CR `')(DX `')(DY `') Relative-coordinate version of `cairo-line-to'. Adds a line to the path from the current point to a point that is offset from the current point by (DX, DY) in user space. After this call the current point will be offset by (DX, DY). Given a current point of (x, y), cairo_rel_line_to(CR, DX, DY) is logically equivalent to cairo_line_to (CR, x + DX, y + DY). It is an error to call this function with no current point. Doing so will cause CR to shutdown with a status of CAIRO_STATUS_NO_CURRENT_POINT. cr a cairo context dx the X offset to the end of the new line dy the Y offset to the end of the new line This documentation was automatically generated. cairo-rel-move-to - Function: cairo-rel-move-to (CR `')(DX `')(DY `') Begin a new sub-path. After this call the current point will offset by (X, Y). Given a current point of (x, y), cairo_rel_move_to(CR, DX, DY) is logically equivalent to cairo_move_to (CR, x + DX, y + DY). It is an error to call this function with no current point. Doing so will cause CR to shutdown with a status of CAIRO_STATUS_NO_CURRENT_POINT. cr a cairo context dx the X offset dy the Y offset This documentation was automatically generated. cairo-pattern-add-color-stop-rgb - Function: cairo-pattern-add-color-stop-rgb (PATTERN `')(OFFSET `')(RED `')(GREEN `')(BLUE `') Adds an opaque color stop to a gradient pattern. The offset specifies the location along the gradient's control vector. For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle. The color is specified in the same way as in `cairo-set-source-rgb'. Note: If the pattern is not a gradient pattern, (eg. a linear or radial pattern), then the pattern will be put into an error status with a status of `CAIRO_STATUS_PATTERN_TYPE_MISMATCH'. pattern a `' offset an offset in the range [0.0 .. 1.0] red red component of color green green component of color blue blue component of color This documentation was automatically generated. cairo-pattern-add-color-stop-rgba - Function: cairo-pattern-add-color-stop-rgba (PATTERN `')(OFFSET `')(RED `')(GREEN `')(BLUE `')(ALPHA `') Adds a translucent color stop to a gradient pattern. The offset specifies the location along the gradient's control vector. For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle. The color is specified in the same way as in `cairo-set-source-rgba'. Note: If the pattern is not a gradient pattern, (eg. a linear or radial pattern), then the pattern will be put into an error status with a status of `CAIRO_STATUS_PATTERN_TYPE_MISMATCH'. pattern a `' offset an offset in the range [0.0 .. 1.0] red red component of color green green component of color blue blue component of color alpha alpha component of color This documentation was automatically generated. cairo-pattern-get-color-stop-rgba - Function: cairo-pattern-get-color-stop-rgba (PATTERN `')(INDEX `') ==>(RET `')(OFFSET `')(RED `')(GREEN `')(BLUE `')(ALPHA `') Gets the color and offset information at the given INDEX for a gradient pattern.

If the pattern is not a gradient pattern, `CAIRO_STATUS_PATTERN_TYPE_MISMATCH' is returned. Since 1.4 This documentation was automatically generated. cairo-pattern-create-rgb - Function: cairo-pattern-create-rgb (RED `')(GREEN `')(BLUE `') ==>(RET `') Creates a new cairo_pattern_t corresponding to an opaque color. The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped. red red component of the color green green component of the color blue blue component of the color ret the newly created `' if successful, or an error pattern in case of no memory. The caller owns the returned object and should call `cairo-pattern-destroy' when finished with it.

The caller owns the returned object and should call `cairo-pattern-destroy' when finished with it. This function will always return a valid pointer, but if an error occurred the pattern status will be set to an error. To inspect the status of a pattern use `cairo-pattern-status'. This documentation was automatically generated. cairo-pattern-get-surface - Function: cairo-pattern-get-surface (PATTERN `') ==>(RET `')(SURFACE `') Gets the surface of a surface pattern. The reference returned in SURFACE is owned by the pattern; the caller should call `cairo-surface-reference' if the surface is to be retained. pattern a `' surface return value for surface of pattern, or ``#f'' ret `CAIRO_STATUS_SUCCESS', or `CAIRO_STATUS_PATTERN_TYPE_MISMATCH' if the pattern is not a surface pattern. Since 1.4 This documentation was automatically generated. cairo-pattern-create-linear - Function: cairo-pattern-create-linear (X0 `')(Y0 `')(X1 `')(Y1 `') ==>(RET `') Create a new linear gradient cairo_pattern_t along the line defined by (x0, y0) and (x1, y1). Before using the gradient pattern, a number of color stops should be defined using `cairo-pattern-add-color-stop-rgb' or `cairo-pattern-add-color-stop-rgba'. Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with `cairo-pattern-set-matrix'. x0 x coordinate of the start point y0 y coordinate of the start point x1 x coordinate of the end point y1 y coordinate of the end point ret the newly created `' if successful, or an error pattern in case of no memory.

Since 1.4 This documentation was automatically generated. cairo-pattern-create-radial - Function: cairo-pattern-create-radial (CX0 `')(CY0 `')(RADIUS0 `')(CX1 `')(CY1 `')(RADIUS1 `') ==>(RET `') Creates a new radial gradient cairo_pattern_t between the two circles defined by (x0, y0, c0) and (x1, y1, c0). Before using the gradient pattern, a number of color stops should be defined using `cairo-pattern-add-color-stop-rgb' or `cairo-pattern-add-color-stop-rgba'. Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with `cairo-pattern-set-matrix'. cx0 x coordinate for the center of the start circle cy0 y coordinate for the center of the start circle radius0 radius of the start circle cx1 x coordinate for the center of the end circle cy1 y coordinate for the center of the end circle radius1 radius of the end circle ret the newly created `' if successful, or an error pattern in case of no memory.

This documentation was automatically generated. cairo-pattern-get-radial-circles - Function: cairo-pattern-get-radial-circles (PATTERN `') ==>(RET `')(X0 `')(Y0 `')(R0 `')(X1 `')(Y1 `')(R1 `') Gets the gradient endpoint circles for a radial gradient, each specified as a center coordinate and a radius. pattern a `' x0 return value for the x coordinate of the center of the first circle, or ``#f'' y0 return value for the y coordinate of the center of the first circle, or ``#f'' r0 return value for the radius of the first circle, or ``#f'' x1 return value for the x coordinate of the center of the second circle, or ``#f'' y1 return value for the y coordinate of the center of the second circle, or ``#f'' r1 return value for the radius of the second circle, or ``#f'' ret `CAIRO_STATUS_SUCCESS', or `CAIRO_STATUS_PATTERN_TYPE_MISMATCH' if PATTERN is not a radial gradient pattern. Since 1.4 This documentation was automatically generated. cairo-pattern-set-extend - Function: cairo-pattern-set-extend (PATTERN `')(EXTEND `') Sets the mode to be used for drawing outside the area of a pattern. See `' for details on the semantics of each extend strategy. pattern a `' extend a `' describing how the area outside of the pattern will be drawn This documentation was automatically generated. cairo-pattern-get-extend - Function: cairo-pattern-get-extend (PATTERN `') ==>(RET `') Gets the current extend mode for a pattern. See `' for details on the semantics of each extend strategy. pattern a `' ret the current extend strategy used for drawing the pattern. This documentation was automatically generated. cairo-pattern-set-filter - Function: cairo-pattern-set-filter (PATTERN `')(FILTER `') Sets the filter to be used for resizing when using this pattern. See `' for details on each filter. pattern a `' filter a `' describing the filter to use for resizing the pattern This documentation was automatically generated. cairo-pattern-get-filter - Function: cairo-pattern-get-filter (PATTERN `') ==>(RET `') Gets the current filter for a pattern. See `' for details on each filter. pattern a `' ret the current filter used for resizing the pattern. This documentation was automatically generated. cairo-pattern-set-matrix - Function: cairo-pattern-set-matrix (PATTERN `')(MATRIX `') Sets the pattern's transformation matrix to MATRIX. This matrix is a transformation from user space to pattern space. When a pattern is first created it always has the identity matrix for its transformation matrix, which means that pattern space is initially identical to user space. Important: Please note that the direction of this transformation matrix is from user space to pattern space. This means that if you imagine the flow from a pattern to user space (and on to device space), then coordinates in that flow will be transformed by the inverse of the pattern matrix. For example, if you want to make a pattern appear twice as large as it does by default the correct code to use is: cairo_matrix_init_scale (&matrix, 0.5, 0.5); cairo_pattern_set_matrix (pattern, &matrix); Meanwhile, using values of 2.0 rather than 0.5 in the code above would cause the pattern to appear at half of its default size. Also, please note the discussion of the user-space locking semantics of `cairo-set-source'. pattern a `' matrix a `' This documentation was automatically generated. cairo-pattern-get-matrix - Function: cairo-pattern-get-matrix (PATTERN `')(MATRIX `') Stores the pattern's transformation matrix into MATRIX. pattern a `' matrix return value for the matrix This documentation was automatically generated. cairo-pattern-get-type - Function: cairo-pattern-get-type (PATTERN `') ==>(RET `') This function returns the type a pattern. See `' for available types. pattern a `' ret The type of PATTERN.

The caller owns the surface and should call cairo_surface_destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use `cairo-surface-status' to check for this. Since 1.2 This documentation was automatically generated. cairo-pdf-surface-set-size - Function: cairo-pdf-surface-set-size (SURFACE `')(WIDTH-IN-POINTS `')(HEIGHT-IN-POINTS `') Changes the size of a PDF surface for the current (and subsequent) pages. This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface or immediately after completing a page with either `cairo-show-page' or `cairo-copy-page'. surface a PDF cairo_surface_t width-in-points new surface width, in points (1 point == 1/72.0 inch) height-in-points new surface height, in points (1 point == 1/72.0 inch) Since 1.2 This documentation was automatically generated. cairo-image-surface-create-from-png - Function: cairo-image-surface-create-from-png (FILENAME `') ==>(RET `') Creates a new image surface and initializes the contents to the given PNG file. filename name of PNG file to load ret a new `' initialized with the contents of the PNG file, or a "nil" surface if any error occurred. A nil surface can be checked for with cairo_surface_status(surface) which may return one of the following values: CAIRO_STATUS_NO_MEMORY CAIRO_STATUS_FILE_NOT_FOUND CAIRO_STATUS_READ_ERROR This documentation was automatically generated. cairo-surface-write-to-png - Function: cairo-surface-write-to-png (SURFACE `')(FILENAME `') ==>(RET `') Writes the contents of SURFACE to a new file FILENAME as a PNG image. surface a `' with pixel contents filename the name of a file to write to ret CAIRO_STATUS_SUCCESS if the PNG file was written successfully. Otherwise, CAIRO_STATUS_NO_MEMORY if memory could not be allocated for the operation or CAIRO_STATUS_SURFACE_TYPE_MISMATCH if the surface does not have pixel contents, or CAIRO_STATUS_WRITE_ERROR if an I/O error occurs while attempting to write the file. This documentation was automatically generated. cairo-ps-surface-create - Function: cairo-ps-surface-create (FILENAME `')(WIDTH-IN-POINTS `')(HEIGHT-IN-POINTS `') ==>(RET `') Creates a PostScript surface of the specified size in points to be written to FILENAME. See `cairo-ps-surface-create-for-stream' for a more flexible mechanism for handling the PostScript output than simply writing it to a named file. Note that the size of individual pages of the PostScript output can vary. See `cairo-ps-surface-set-size'. filename a filename for the PS output (must be writable) width-in-points width of the surface, in points (1 point == 1/72.0 inch) height-in-points height of the surface, in points (1 point == 1/72.0 inch) ret a pointer to the newly created surface. The caller owns the surface and should call cairo_surface_destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use `cairo-surface-status' to check for this. Since 1.2 This documentation was automatically generated. cairo-ps-surface-set-size - Function: cairo-ps-surface-set-size (SURFACE `')(WIDTH-IN-POINTS `')(HEIGHT-IN-POINTS `') Changes the size of a PostScript surface for the current (and subsequent) pages. This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface or immediately after completing a page with either `cairo-show-page' or `cairo-copy-page'. surface a PostScript cairo_surface_t width-in-points new surface width, in points (1 point == 1/72.0 inch) height-in-points new surface height, in points (1 point == 1/72.0 inch) Since 1.2 This documentation was automatically generated. cairo-ps-surface-dsc-comment - Function: cairo-ps-surface-dsc-comment (SURFACE `')(COMMENT `') Emit a comment into the PostScript output for the given surface. The comment is expected to conform to the PostScript Language Document Structuring Conventions (DSC). Please see that manual for details on the available comments and their meanings. In particular, the %`IncludeFeature' comment allows a device-independent means of controlling printer device features. So the PostScript Printer Description Files Specification will also be a useful reference. The comment string must begin with a percent character (%) and the total length of the string (including any initial percent characters) must not exceed 255 characters. Violating either of these conditions will place SURFACE into an error state. But beyond these two conditions, this function will not enforce conformance of the comment with any particular specification. The comment string should not have a trailing newline. The DSC specifies different sections in which particular comments can appear. This function provides for comments to be emitted within three sections: the header, the Setup section, and the PageSetup section. Comments appearing in the first two sections apply to the entire document while comments in the BeginPageSetup section apply only to a single page. For comments to appear in the header section, this function should be called after the surface is created, but before a call to `cairo-ps-surface-begin-setup'. For comments to appear in the Setup section, this function should be called after a call to `cairo-ps-surface-begin-setup' but before a call to `cairo-ps-surface-begin-page-setup'. For comments to appear in the PageSetup section, this function should be called after a call to `cairo-ps-surface-begin-page-setup'. Note that it is only necessary to call `cairo-ps-surface-begin-page-setup' for the first page of any surface. After a call to `cairo-show-page' or `cairo-copy-page' comments are unambiguously directed to the PageSetup section of the current page. But it doesn't hurt to call this function at the beginning of every page as that consistency may make the calling code simpler. As a final note, cairo automatically generates several comments on its own. As such, applications must not manually generate any of the following comments: Header section: %!PS-Adobe-3.0, %`Creator', %`CreationDate', %`Pages', %`BoundingBox', %`DocumentData', %`LanguageLevel', %`EndComments'. Setup section: %`BeginSetup', %`EndSetup' PageSetup section: %`BeginPageSetup', %`PageBoundingBox', %`EndPageSetup'. Other sections: %`BeginProlog', %`EndProlog', %`Page', %`Trailer', %`EOF' Here is an example sequence showing how this function might be used: cairo_surface_t *surface = cairo_ps_surface_create (filename, width, height); ... cairo_ps_surface_dsc_comment (surface, "%%Title: My excellent document"); cairo_ps_surface_dsc_comment (surface, "%%Copyright: Copyright (C) 2006 Cairo Lover") ... cairo_ps_surface_dsc_begin_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor White"); ... cairo_ps_surface_dsc_begin_page_setup (surface); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A3"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *InputSlot LargeCapacity"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaType Glossy"); cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor Blue"); ... draw to first page here .. cairo_show_page (cr); ... cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A5"); ... surface a PostScript cairo_surface_t comment a comment string to be emitted into the PostScript output Since 1.2 This documentation was automatically generated. cairo-scaled-font-create - Function: cairo-scaled-font-create (FONT-FACE `')(FONT-MATRIX `')(CTM `')(OPTIONS `') ==>(RET `') Creates a `' object from a font face and matrices that describe the size of the font and the environment in which it will be used. font-face a `' font-matrix font space to user space transformation matrix for the font. In the simplest case of a N point font, this matrix is just a scale by N, but it can also be used to shear the font or stretch it unequally along the two axes.

The extents describe a user-space rectangle that encloses the "inked" portion of the text drawn at the origin (0,0) (as it would be drawn by `cairo-show-text' if the cairo graphics state were set to the same font_face, font_matrix, ctm, and font_options as SCALED-FONT). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by `cairo-show-text'. Note that whitespace characters do not directly contribute to the size of the rectangle (extents.width and extents.height). They do contribute indirectly by changing the position of non-whitespace characters. In particular, trailing whitespace characters are likely to not affect the size of the rectangle, though they will affect the x_advance and y_advance values. scaled-font a `' utf8 a string of text, encoded in UTF-8 extents a `' which to store the retrieved extents. Since 1.2 This documentation was automatically generated. cairo-scaled-font-glyph-extents - Function: cairo-scaled-font-glyph-extents (SCALED-FONT `')(GLYPHS `')(NUM-GLYPHS `')(EXTENTS `') Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by `cairo-show-glyphs' if the cairo graphics state were set to the same font_face, font_matrix, ctm, and font_options as SCALED-FONT). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by cairo_show_glyphs.

Since 1.2 This documentation was automatically generated. cairo-scaled-font-get-font-options - Function: cairo-scaled-font-get-font-options (SCALED-FONT `')(OPTIONS `') Stores the font options with which SCALED-FONT was created into OPTIONS. scaled-font a `' options return value for the font options Since 1.2 This documentation was automatically generated. cairo-scaled-font-get-font-matrix - Function: cairo-scaled-font-get-font-matrix (SCALED-FONT `')(FONT-MATRIX `') Stores the font matrix with which SCALED-FONT was created into MATRIX. scaled-font a `' font-matrix return value for the matrix Since 1.2 This documentation was automatically generated. cairo-scaled-font-get-ctm - Function: cairo-scaled-font-get-ctm (SCALED-FONT `')(CTM `') Stores the CTM with which SCALED-FONT was created into CTM. scaled-font a `' ctm return value for the CTM Since 1.2 This documentation was automatically generated. cairo-scaled-font-get-type - Function: cairo-scaled-font-get-type (SCALED-FONT `') ==>(RET `') This function returns the type of the backend used to create a scaled font. See `' for available types. scaled-font a `' ret The type of SCALED-FONT. Since 1.2 This documentation was automatically generated. cairo-surface-create-similar - Function: cairo-surface-create-similar (OTHER `')(CONTENT `')(WIDTH `')(HEIGHT `') ==>(RET `') Create a new surface that is as compatible as possible with an existing surface. For example the new surface will have the same fallback resolution and font options as OTHER. Generally, the new surface will also use the same backend as OTHER, unless that is not possible for some reason. The type of the returned surface may be examined with `cairo-surface-get-type'. Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.) other an existing surface used to select the backend of the new surface content the content for the new surface width width of the new surface, (in device-space units) height height of the new surface (in device-space units) ret a pointer to the newly allocated surface. The caller owns the surface and should call cairo_surface_destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if OTHER is already in an error state or any other error occurs. This documentation was automatically generated. cairo-surface-finish - Function: cairo-surface-finish (SURFACE `') This function finishes the surface and drops all references to external resources. For example, for the Xlib backend it means that cairo will no longer access the drawable, which can be freed. After calling `cairo-surface-finish' the only valid operations on a surface are getting and setting user data and referencing and destroying it. Further drawing to the surface will not affect the surface but will instead trigger a CAIRO_STATUS_SURFACE_FINISHED error. When the last call to `cairo-surface-destroy' decreases the reference count to zero, cairo will call `cairo-surface-finish' if it hasn't been called already, before freeing the resources associated with the surface. surface the `' to finish This documentation was automatically generated. cairo-surface-flush - Function: cairo-surface-flush (SURFACE `') Do any pending drawing for the surface and also restore any temporary modification's cairo has made to the surface's state. This function must be called before switching from drawing on the surface with cairo to drawing on it directly with native APIs. If the surface doesn't support direct access, then this function does nothing. surface a `' This documentation was automatically generated. cairo-surface-get-font-options - Function: cairo-surface-get-font-options (SURFACE `')(OPTIONS `') Retrieves the default font rendering options for the surface. This allows display surfaces to report the correct subpixel order for rendering on them, print surfaces to disable hinting of metrics and so forth. The result can then be used with `cairo-scaled-font-create'. surface a `' options a `' object into which to store the retrieved options. All existing values are overwritten This documentation was automatically generated. cairo-surface-get-content - Function: cairo-surface-get-content (SURFACE `') ==>(RET `') This function returns the content type of SURFACE which indicates whether the surface contains color and/or alpha information. See `'. surface a `' ret The content type of SURFACE. Since 1.2 This documentation was automatically generated. cairo-surface-mark-dirty - Function: cairo-surface-mark-dirty (SURFACE `') Tells cairo that drawing has been done to surface using means other than cairo, and that cairo should reread any cached areas. Note that you must call `cairo-surface-flush' before doing such drawing. surface a `' This documentation was automatically generated. cairo-surface-mark-dirty-rectangle - Function: cairo-surface-mark-dirty-rectangle (SURFACE `')(X `')(Y `')(WIDTH `')(HEIGHT `') Like `cairo-surface-mark-dirty', but drawing has been done only to the specified rectangle, so that cairo can retain cached contents for other parts of the surface. Any cached clip set on the surface will be reset by this function, to make sure that future cairo calls have the clip set that they expect. surface a `' x X coordinate of dirty rectangle y Y coordinate of dirty rectangle width width of dirty rectangle height height of dirty rectangle This documentation was automatically generated. cairo-surface-set-device-offset - Function: cairo-surface-set-device-offset (SURFACE `')(X-OFFSET `')(Y-OFFSET `') Sets an offset that is added to the device coordinates determined by the CTM when drawing to SURFACE. One use case for this function is when we want to create a `' that redirects drawing for a portion of an onscreen surface to an offscreen surface in a way that is completely invisible to the user of the cairo API. Setting a transformation via `cairo-translate' isn't sufficient to do this, since functions like `cairo-device-to-user' will expose the hidden offset. Note that the offset affects drawing to the surface as well as using the surface in a source pattern. surface a `' x-offset the offset in the X direction, in device units y-offset the offset in the Y direction, in device units This documentation was automatically generated. cairo-surface-get-device-offset - Function: cairo-surface-get-device-offset (SURFACE `') ==>(X-OFFSET `')(Y-OFFSET `') This function returns the previous device offset set by `cairo-surface-set-device-offset'. surface a `' x-offset the offset in the X direction, in device units y-offset the offset in the Y direction, in device units Since 1.2 This documentation was automatically generated. cairo-surface-get-type - Function: cairo-surface-get-type (SURFACE `') ==>(RET `') This function returns the type of the backend used to create a surface. See `' for available types. surface a `' ret The type of SURFACE. Since 1.2 This documentation was automatically generated. cairo-svg-surface-create - Function: cairo-svg-surface-create (FILENAME `')(WIDTH-IN-POINTS `')(HEIGHT-IN-POINTS `') ==>(RET `') Creates a SVG surface of the specified size in points to be written to FILENAME. filename a filename for the SVG output (must be writable) width-in-points width of the surface, in points (1 point == 1/72.0 inch) height-in-points height of the surface, in points (1 point == 1/72.0 inch) ret a pointer to the newly created surface. The caller owns the surface and should call cairo_surface_destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use `cairo-surface-status' to check for this. Since 1.2 This documentation was automatically generated. cairo-select-font-face - Function: cairo-select-font-face (CR `')(FAMILY `')(SLANT `')(WEIGHT `') Selects a family and style of font from a simplified description as a family name, slant and weight. This function is meant to be used only for applications with simple font needs: Cairo doesn't provide for operations such as listing all available fonts on the system, and it is expected that most applications will need to use a more comprehensive font handling and text layout library in addition to cairo. cr a `' family a font family name, encoded in UTF-8 slant the slant for the font weight the weight for the font This documentation was automatically generated. cairo-set-font-size - Function: cairo-set-font-size (CR `')(SIZE `') Sets the current font matrix to a scale by a factor of SIZE, replacing any font matrix previously set with `cairo-set-font-size' or `cairo-set-font-matrix'. This results in a font size of SIZE user space units. (More precisely, this matrix will result in the font's em-square being a SIZE by SIZE square in user space.) cr a `' size the new font size, in user space units This documentation was automatically generated. cairo-set-font-matrix - Function: cairo-set-font-matrix (CR `')(MATRIX `') Sets the current font matrix to MATRIX. The font matrix gives a transformation from the design space of the font (in this space, the em-square is 1 unit by 1 unit) to user space. Normally, a simple scale is used (see `cairo-set-font-size'), but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes cr a `' matrix a `' describing a transform to be applied to the current font. This documentation was automatically generated. cairo-get-font-matrix - Function: cairo-get-font-matrix (CR `')(MATRIX `') Stores the current font matrix into MATRIX. See `cairo-set-font-matrix'. cr a `' matrix return value for the matrix This documentation was automatically generated. cairo-set-font-options - Function: cairo-set-font-options (CR `')(OPTIONS `') Sets a set of custom font rendering options for the `'. Rendering options are derived by merging these options with the options derived from underlying surface; if the value in OPTIONS has a default value (like `CAIRO_ANTIALIAS_DEFAULT'), then the value from the surface is used. cr a `' options font options to use This documentation was automatically generated. cairo-get-font-options - Function: cairo-get-font-options (CR `')(OPTIONS `') Retrieves font rendering options set via `'. Note that the returned options do not include any options derived from the underlying surface; they are literally the options passed to `cairo-set-font-options'. cr a `' options a `' object into which to store the retrieved options. All existing values are overwritten This documentation was automatically generated. cairo-set-font-face - Function: cairo-set-font-face (CR `')(FONT-FACE `') Replaces the current `' object in the `' with FONT-FACE. The replaced font face in the `' will be destroyed if there are no other references to it. cr a `' font-face a `', or ``#f'' to restore to the default font This documentation was automatically generated. cairo-get-font-face - Function: cairo-get-font-face (CR `') ==>(RET `') Gets the current font face for a `'. cr a `' ret the current font face. This object is owned by cairo. To keep a reference to it, you must call cairo_font_face_reference. This function never returns ``#f''. If memory cannot be allocated, a special "nil" `' object will be returned on which `cairo-font-face-status' returns `CAIRO_STATUS_NO_MEMORY'. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling `cairo-set-font-face' with a nil font will trigger an error that will shutdown the cairo_t object). This documentation was automatically generated. cairo-set-scaled-font - Function: cairo-set-scaled-font (CR `')(SCALED-FONT `') Replaces the current font face, font matrix, and font options in the `' with those of the `'. Except for some translation, the current CTM of the `' should be the same as that of the `', which can be accessed using `cairo-scaled-font-get-ctm'. cr a `' scaled-font a `' Since 1.2 This documentation was automatically generated. cairo-get-scaled-font - Function: cairo-get-scaled-font (CR `') ==>(RET `') Gets the current scaled font for a `'. cr a `' ret the current scaled font. This object is owned by cairo. To keep a reference to it, you must call `cairo-scaled-font-reference'. This function never returns ``#f''. If memory cannot be allocated, a special "nil" `' object will be returned on which `cairo-scaled-font-status' returns `CAIRO_STATUS_NO_MEMORY'. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling `cairo-set-scaled-font' with a nil font will trigger an error that will shutdown the cairo_t object). Since 1.4 This documentation was automatically generated. cairo-show-text - Function: cairo-show-text (CR `')(UTF8 `') A drawing operator that generates the shape from a string of UTF-8 characters, rendered according to the current font_face, font_size (font_matrix), and font_options. This function first computes a set of glyphs for the string of text. The first glyph is placed so that its origin is at the current point. The origin of each subsequent glyph is offset from that of the previous glyph by the advance values of the previous glyph. After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for easy display of a single logical string with multiple calls to `cairo-show-text'. NOTE: The `cairo-show-text' function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See `cairo-show-glyphs' for the "real" text display API in cairo. cr a cairo context utf8 a string of text encoded in UTF-8 This documentation was automatically generated. cairo-show-glyphs - Function: cairo-show-glyphs (CR `')(GLYPHS `')(NUM-GLYPHS `') A drawing operator that generates the shape from an array of glyphs, rendered according to the current font_face, font_size (font_matrix), and font_options. cr a cairo context glyphs array of glyphs to show num-glyphs number of glyphs to show This documentation was automatically generated. cairo-font-extents - Function: cairo-font-extents (CR `')(EXTENTS `') Gets the font extents for the currently selected font. cr a `' extents a `' object into which the results will be stored. This documentation was automatically generated. cairo-text-extents - Function: cairo-text-extents (CR `')(UTF8 `')(EXTENTS `') Gets the extents for a string of text. The extents describe a user-space rectangle that encloses the "inked" portion of the text, (as it would be drawn by `cairo-show-text'). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by `cairo-show-text'. Note that whitespace characters do not directly contribute to the size of the rectangle (extents.width and extents.height). They do contribute indirectly by changing the position of non-whitespace characters. In particular, trailing whitespace characters are likely to not affect the size of the rectangle, though they will affect the x_advance and y_advance values. cr a `' utf8 a string of text, encoded in UTF-8 extents a `' object into which the results will be stored This documentation was automatically generated. cairo-glyph-extents - Function: cairo-glyph-extents (CR `')(GLYPHS `')(NUM-GLYPHS `')(EXTENTS `') Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by `cairo-show-glyphs'). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by cairo_show_glyphs. Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height). cr a `' glyphs an array of `' objects num-glyphs the number of elements in GLYPHS extents a `' object into which the results will be stored This documentation was automatically generated. cairo-translate - Function: cairo-translate (CR `')(TX `')(TY `') Modifies the current transformation matrix (CTM) by translating the user-space origin by (TX, TY). This offset is interpreted as a user-space coordinate according to the CTM in place before the new call to cairo_translate. In other words, the translation of the user-space origin takes place after any existing transformation. cr a cairo context tx amount to translate in the X direction ty amount to translate in the Y direction This documentation was automatically generated. cairo-scale - Function: cairo-scale (CR `')(SX `')(SY `') Modifies the current transformation matrix (CTM) by scaling the X and Y user-space axes by SX and SY respectively. The scaling of the axes takes place after any existing transformation of user space. cr a cairo context sx scale factor for the X dimension sy scale factor for the Y dimension This documentation was automatically generated. cairo-rotate - Function: cairo-rotate (CR `')(ANGLE `') Modifies the current transformation matrix (CTM) by rotating the user-space axes by ANGLE radians. The rotation of the axes takes places after any existing transformation of user space. The rotation direction for positive angles is from the positive X axis toward the positive Y axis. cr a cairo context angle angle (in radians) by which the user-space axes will be rotated This documentation was automatically generated. cairo-transform - Function: cairo-transform (CR `')(MATRIX `') Modifies the current transformation matrix (CTM) by applying MATRIX as an additional transformation. The new transformation of user space takes place after any existing transformation. cr a cairo context matrix a transformation to be applied to the user-space axes This documentation was automatically generated. cairo-set-matrix - Function: cairo-set-matrix (CR `')(MATRIX `') Modifies the current transformation matrix (CTM) by setting it equal to MATRIX. cr a cairo context matrix a transformation matrix from user space to device space This documentation was automatically generated. cairo-get-matrix - Function: cairo-get-matrix (CR `')(MATRIX `') Stores the current transformation matrix (CTM) into MATRIX. cr a cairo context matrix return value for the matrix This documentation was automatically generated. cairo-identity-matrix - Function: cairo-identity-matrix (CR `') Resets the current transformation matrix (CTM) by setting it equal to the identity matrix. That is, the user-space and device-space axes will be aligned and one user-space unit will transform to one device-space unit. cr a cairo context This documentation was automatically generated. cairo-user-to-device - Function: cairo-user-to-device (CR `') ==>(X `')(Y `') Transform a coordinate from user space to device space by multiplying the given point by the current transformation matrix (CTM). cr a cairo context x X value of coordinate (in/out parameter) y Y value of coordinate (in/out parameter) This documentation was automatically generated. cairo-user-to-device-distance - Function: cairo-user-to-device-distance (CR `') ==>(DX `')(DY `') Transform a distance vector from user space to device space. This function is similar to `cairo-user-to-device' except that the translation components of the CTM will be ignored when transforming (DX,DY). cr a cairo context dx X component of a distance vector (in/out parameter) dy Y component of a distance vector (in/out parameter) This documentation was automatically generated. cairo-device-to-user - Function: cairo-device-to-user (CR `') ==>(X `')(Y `') Transform a coordinate from device space to user space by multiplying the given point by the inverse of the current transformation matrix (CTM). cr a cairo x X value of coordinate (in/out parameter) y Y value of coordinate (in/out parameter) This documentation was automatically generated. cairo-device-to-user-distance - Function: cairo-device-to-user-distance (CR `') ==>(DX `')(DY `') Transform a distance vector from device space to user space. This function is similar to `cairo-device-to-user' except that the translation components of the inverse CTM will be ignored when transforming (DX,DY). cr a cairo context dx X component of a distance vector (in/out parameter) dy Y component of a distance vector (in/out parameter) This documentation was automatically generated. cairo-version - Function: cairo-version ==>(RET `') Returns the version of the cairo library encoded in a single integer as per CAIRO_VERSION_ENCODE. The encoding ensures that later versions compare greater than earlier versions. A run-time comparison to check that cairo's version is greater than or equal to version X.Y.Z could be performed as follows: if (cairo_version() >= CAIRO_VERSION_ENCODE(X,Y,Z)) {...} See also `cairo-version-string' as well as the compile-time equivalents `CAIRO_VERSION' and `CAIRO_VERSION_STRING'. ret the encoded version. This documentation was automatically generated. cairo-version-string - Function: cairo-version-string ==>(RET `') Returns the version of the cairo library as a human-readable string of the form "X.Y.Z". See also `cairo-version' as well as the compile-time equivalents `CAIRO_VERSION_STRING' and `CAIRO_VERSION'. ret a string containing the version. This documentation was automatically generated. cairo-create - Function: cairo-create (TARGET `') ==>(RET `') Creates a new `' with all graphics state parameters set to default values and with TARGET as a target surface. The target surface should be constructed with a backend-specific function such as `cairo-image-surface-create' (or any other `cairo__surface_create' variant). This function references TARGET, so you can immediately call `cairo-surface-destroy' on it if you don't need to maintain a separate reference to it. target target surface for the context ret a newly allocated `' with a reference count of 1. The initial reference count should be released with `cairo-destroy' when you are done using the `'. This function never returns ``#f''. If memory cannot be allocated, a special `' object will be returned on which `cairo-status' returns `CAIRO_STATUS_NO_MEMORY'. You can use this object normally, but no drawing will be done. This documentation was automatically generated. cairo-save - Function: cairo-save (CR `') Makes a copy of the current state of CR and saves it on an internal stack of saved states for CR. When `cairo-restore' is called, CR will be restored to the saved state. Multiple calls to `cairo-save' and `cairo-restore' can be nested; each call to `cairo-restore' restores the state from the matching paired `cairo-save'. It isn't necessary to clear all saved states before a `' is freed. If the reference count of a `' drops to zero in response to a call to `cairo-destroy', any saved states will be freed along with the `'. cr a `' This documentation was automatically generated. cairo-restore - Function: cairo-restore (CR `') Restores CR to the state saved by a preceding call to `cairo-save' and removes that state from the stack of saved states. cr a `' This documentation was automatically generated. cairo-get-target - Function: cairo-get-target (CR `') ==>(RET `') Gets the target surface for the cairo context as passed to `cairo-create'. This function will always return a valid pointer, but the result can be a "nil" surface if CR is already in an error state, (ie. `cairo-status'`!='`CAIRO_STATUS_SUCCESS'). A nil surface is indicated by `cairo-surface-status'`!='`CAIRO_STATUS_SUCCESS'. cr a cairo context ret the target surface. This object is owned by cairo. To keep a reference to it, you must call `cairo-surface-reference'. This documentation was automatically generated. cairo-push-group - Function: cairo-push-group (CR `') Temporarily redirects drawing to an intermediate surface known as a group. The redirection lasts until the group is completed by a call to `cairo-pop-group' or `cairo-pop-group-to-source'. These calls provide the result of any drawing to the group as a pattern, (either as an explicit object, or set as the source pattern). This group functionality can be convenient for performing intermediate compositing. One common use of a group is to render objects as opaque within the group, (so that they occlude each other), and then blend the result with translucence onto the destination. Groups can be nested arbitrarily deep by making balanced calls to `cairo-push-group'/`cairo-pop-group'. Each call pushes/pops the new target group onto/from a stack. The `cairo-push-group' function calls `cairo-save' so that any changes to the graphics state will not be visible outside the group, (the pop_group functions call `cairo-restore'). By default the intermediate group will have a content type of CAIRO_CONTENT_COLOR_ALPHA. Other content types can be chosen for the group by using `cairo-push-group-with-content' instead. As an example, here is how one might fill and stroke a path with translucence, but without any portion of the fill being visible under the stroke: cairo_push_group (cr); cairo_set_source (cr, fill_pattern); cairo_fill_preserve (cr); cairo_set_source (cr, stroke_pattern); cairo_stroke (cr); cairo_pop_group_to_source (cr); cairo_paint_with_alpha (cr, alpha); cr a cairo context Since 1.2 This documentation was automatically generated. cairo-pop-group - Function: cairo-pop-group (CR `') ==>(RET `') Terminates the redirection begun by a call to `cairo-push-group' or `cairo-push-group-with-content' and returns a new pattern containing the results of all drawing operations performed to the group. The `cairo-pop-group' function calls `cairo-restore', (balancing a call to `cairo-save' by the push_group function), so that any changes to the graphics state will not be visible outside the group. cr a cairo context ret a newly created (surface) pattern containing the results of all drawing operations performed to the group. The caller owns the returned object and should call `cairo-pattern-destroy' when finished with it. Since 1.2 This documentation was automatically generated. cairo-pop-group-to-source - Function: cairo-pop-group-to-source (CR `') Terminates the redirection begun by a call to `cairo-push-group' or `cairo-push-group-with-content' and installs the resulting pattern as the source pattern in the given cairo context. The behavior of this function is equivalent to the sequence of operations: cairo_pattern_t *group = cairo_pop_group (cr); cairo_set_source (cr, group); cairo_pattern_destroy (group); but is more convenient as their is no need for a variable to store the short-lived pointer to the pattern. The `cairo-pop-group' function calls `cairo-restore', (balancing a call to `cairo-save' by the push_group function), so that any changes to the graphics state will not be visible outside the group. cr a cairo context Since 1.2 This documentation was automatically generated. cairo-get-group-target - Function: cairo-get-group-target (CR `') ==>(RET `') Gets the target surface for the current group as started by the most recent call to `cairo-push-group' or `cairo-push-group-with-content'. This function will return NULL if called "outside" of any group rendering blocks, (that is, after the last balancing call to `cairo-pop-group' or `cairo-pop-group-to-source'). cr a cairo context ret the target group surface, or NULL if none. This object is owned by cairo. To keep a reference to it, you must call `cairo-surface-reference'. Since 1.2 This documentation was automatically generated. cairo-set-source-rgb - Function: cairo-set-source-rgb (CR `')(RED `')(GREEN `')(BLUE `') Sets the source pattern within CR to an opaque color. This opaque color will then be used for any subsequent drawing operation until a new source pattern is set. The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped. cr a cairo context red red component of color green green component of color blue blue component of color This documentation was automatically generated. cairo-set-source-rgba - Function: cairo-set-source-rgba (CR `')(RED `')(GREEN `')(BLUE `')(ALPHA `') Sets the source pattern within CR to a translucent color. This color will then be used for any subsequent drawing operation until a new source pattern is set. The color and alpha components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped. cr a cairo context red red component of color green green component of color blue blue component of color alpha alpha component of color This documentation was automatically generated. cairo-set-source - Function: cairo-set-source (CR `')(SOURCE `') Sets the source pattern within CR to SOURCE. This pattern will then be used for any subsequent drawing operation until a new source pattern is set. Note: The pattern's transformation matrix will be locked to the user space in effect at the time of `cairo-set-source'. This means that further modifications of the current transformation matrix will not affect the source pattern. See `cairo-pattern-set-matrix'. XXX: I'd also like to direct the reader's attention to some (not-yet-written) section on cairo's imaging model. How would I do that if such a section existed? (cworth). cr a cairo context source a `' to be used as the source for subsequent drawing operations. This documentation was automatically generated. cairo-set-source-surface - Function: cairo-set-source-surface (CR `')(SURFACE `')(X `')(Y `') This is a convenience function for creating a pattern from SURFACE and setting it as the source in CR with `cairo-set-source'. The X and Y parameters give the user-space coordinate at which the surface origin should appear. (The surface origin is its upper-left corner before any transformation has been applied.) The X and Y patterns are negated and then set as translation values in the pattern matrix. Other than the initial translation pattern matrix, as described above, all other pattern attributes, (such as its extend mode), are set to the default values as in `cairo-pattern-create-for-surface'. The resulting pattern can be queried with `cairo-get-source' so that these attributes can be modified if desired, (eg. to create a repeating pattern with `cairo-pattern-set-extend'). cr a cairo context surface a surface to be used to set the source pattern x User-space X coordinate for surface origin y User-space Y coordinate for surface origin This documentation was automatically generated. cairo-get-source - Function: cairo-get-source (CR `') ==>(RET `') Gets the current source pattern for CR. cr a cairo context ret the current source pattern. This object is owned by cairo. To keep a reference to it, you must call `cairo-pattern-reference'. This documentation was automatically generated. cairo-set-antialias - Function: cairo-set-antialias (CR `')(ANTIALIAS `') Set the antialiasing mode of the rasterizer used for drawing shapes. This value is a hint, and a particular backend may or may not support a particular value. At the current time, no backend supports `CAIRO_ANTIALIAS_SUBPIXEL' when drawing shapes. Note that this option does not affect text rendering, instead see `cairo-font-options-set-antialias'. cr a `' antialias the new antialiasing mode This documentation was automatically generated. cairo-get-antialias - Function: cairo-get-antialias (CR `') ==>(RET `') Gets the current shape antialiasing mode, as set by `cairo-set-shape-antialias'. cr a cairo context ret the current shape antialiasing mode. This documentation was automatically generated. cairo-set-dash - Function: cairo-set-dash (CR `') ==>(DASHES `')(NUM-DASHES `')(OFFSET `') Sets the dash pattern to be used by `cairo-stroke'. A dash pattern is specified by DASHES, an array of positive values. Each value provides the length of alternate "on" and "off" portions of the stroke. The OFFSET specifies an offset into the pattern at which the stroke begins. Each "on" segment will have caps applied as if the segment were a separate sub-path. In particular, it is valid to use an "on" length of 0.0 with CAIRO_LINE_CAP_ROUND or CAIRO_LINE_CAP_SQUARE in order to distributed dots or squares along a path. Note: The length values are in user-space units as evaluated at the time of stroking. This is not necessarily the same as the user space at the time of `cairo-set-dash'. If NUM-DASHES is 0 dashing is disabled. If NUM-DASHES is 1 a symmetric pattern is assumed with alternating on and off portions of the size specified by the single value in DASHES. If any value in DASHES is negative, or if all values are 0, then CAIRO-T will be put into an error state with a status of `'. cr a cairo context dashes an array specifying alternate lengths of on and off stroke portions num-dashes the length of the dashes array offset an offset into the dash pattern at which the stroke should start This documentation was automatically generated. cairo-get-dash-count - Function: cairo-get-dash-count (CR `') ==>(RET `') This function returns the length of the dash array in CR (0 if dashing is not currently in effect). See also `cairo-set-dash' and `cairo-get-dash'. cr a `' ret the length of the dash array, or 0 if no dash array set. Since 1.4 This documentation was automatically generated. cairo-set-fill-rule - Function: cairo-set-fill-rule (CR `')(FILL-RULE `') Set the current fill rule within the cairo context. The fill rule is used to determine which regions are inside or outside a complex (potentially self-intersecting) path. The current fill rule affects both cairo_fill and cairo_clip. See `' for details on the semantics of each available fill rule. cr a `' fill-rule a fill rule, specified as a `' This documentation was automatically generated. cairo-get-fill-rule - Function: cairo-get-fill-rule (CR `') ==>(RET `') Gets the current fill rule, as set by `cairo-set-fill-rule'. cr a cairo context ret the current fill rule. This documentation was automatically generated. cairo-set-line-cap - Function: cairo-set-line-cap (CR `')(LINE-CAP `') Sets the current line cap style within the cairo context. See `' for details about how the available line cap styles are drawn. As with the other stroke parameters, the current line cap style is examined by `cairo-stroke', `cairo-stroke-extents', and `cairo-stroke-to-path', but does not have any effect during path construction. cr a cairo context line-cap a line cap style This documentation was automatically generated. cairo-get-line-cap - Function: cairo-get-line-cap (CR `') ==>(RET `') Gets the current line cap style, as set by `cairo-set-line-cap'. cr a cairo context ret the current line cap style. This documentation was automatically generated. cairo-set-line-join - Function: cairo-set-line-join (CR `')(LINE-JOIN `') Sets the current line join style within the cairo context. See `' for details about how the available line join styles are drawn. As with the other stroke parameters, the current line join style is examined by `cairo-stroke', `cairo-stroke-extents', and `cairo-stroke-to-path', but does not have any effect during path construction. cr a cairo context line-join a line joint style This documentation was automatically generated. cairo-get-line-join - Function: cairo-get-line-join (CR `') ==>(RET `') Gets the current line join style, as set by `cairo-set-line-join'. cr a cairo context ret the current line join style. This documentation was automatically generated. cairo-set-line-width - Function: cairo-set-line-width (CR `')(WIDTH `') Sets the current line width within the cairo context. The line width value specifies the diameter of a pen that is circular in user space, (though device-space pen may be an ellipse in general due to scaling/shear/rotation of the CTM). Note: When the description above refers to user space and CTM it refers to the user space and CTM in effect at the time of the stroking operation, not the user space and CTM in effect at the time of the call to `cairo-set-line-width'. The simplest usage makes both of these spaces identical. That is, if there is no change to the CTM between a call to `cairo-set-line-with' and the stroking operation, then one can just pass user-space values to `cairo-set-line-width' and ignore this note. As with the other stroke parameters, the current line width is examined by `cairo-stroke', `cairo-stroke-extents', and `cairo-stroke-to-path', but does not have any effect during path construction. The default line width value is 2.0. cr a `' width a line width This documentation was automatically generated. cairo-get-line-width - Function: cairo-get-line-width (CR `') ==>(RET `') This function returns the current line width value exactly as set by `cairo-set-line-width'. Note that the value is unchanged even if the CTM has changed between the calls to `cairo-set-line-width' and `cairo-get-line-width'. cr a cairo context ret the current line width. This documentation was automatically generated. cairo-set-miter-limit - Function: cairo-set-miter-limit (CR `')(LIMIT `') Sets the current miter limit within the cairo context. If the current line join style is set to `CAIRO_LINE_JOIN_MITER' (see `cairo-set-line-join'), the miter limit is used to determine whether the lines should be joined with a bevel instead of a miter. Cairo divides the length of the miter by the line width. If the result is greater than the miter limit, the style is converted to a bevel. As with the other stroke parameters, the current line miter limit is examined by `cairo-stroke', `cairo-stroke-extents', and `cairo-stroke-to-path', but does not have any effect during path construction. cr a cairo context limit miter limit to set This documentation was automatically generated. cairo-get-miter-limit - Function: cairo-get-miter-limit (CR `') ==>(RET `') Gets the current miter limit, as set by `cairo-set-miter-limit'. cr a cairo context ret the current miter limit. This documentation was automatically generated. cairo-set-operator - Function: cairo-set-operator (CR `')(OP `') Sets the compositing operator to be used for all drawing operations. See `' for details on the semantics of each available compositing operator. XXX: I'd also like to direct the reader's attention to some (not-yet-written) section on cairo's imaging model. How would I do that if such a section existed? (cworth). cr a `' op a compositing operator, specified as a `' This documentation was automatically generated. cairo-get-operator - Function: cairo-get-operator (CR `') ==>(RET `') Gets the current compositing operator for a cairo context. cr a cairo context ret the current compositing operator. This documentation was automatically generated. cairo-set-tolerance - Function: cairo-set-tolerance (CR `')(TOLERANCE `') Sets the tolerance used when converting paths into trapezoids. Curved segments of the path will be subdivided until the maximum deviation between the original path and the polygonal approximation is less than TOLERANCE. The default value is 0.1. A larger value will give better performance, a smaller value, better appearance. (Reducing the value from the default value of 0.1 is unlikely to improve appearance significantly.) cr a `' tolerance the tolerance, in device units (typically pixels) This documentation was automatically generated. cairo-get-tolerance - Function: cairo-get-tolerance (CR `') ==>(RET `') Gets the current tolerance value, as set by `cairo-set-tolerance'. cr a cairo context ret the current tolerance value. This documentation was automatically generated. cairo-clip - Function: cairo-clip (CR `') Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by `cairo-fill' and according to the current fill rule (see `cairo-set-fill-rule'). After cairo_clip, the current path will be cleared from the cairo context. The current clip region affects all drawing operations by effectively masking out any changes to the surface that are outside the current clip region. Calling `cairo-clip' can only make the clip region smaller, never larger. But the current clip is part of the graphics state, so a temporary restriction of the clip region can be achieved by calling `cairo-clip' within a `cairo-save'/`cairo-restore' pair. The only other means of increasing the size of the clip region is `cairo-reset-clip'. cr a cairo context This documentation was automatically generated. cairo-clip-preserve - Function: cairo-clip-preserve (CR `') Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by `cairo-fill' and according to the current fill rule (see `cairo-set-fill-rule'). Unlike `cairo-clip', cairo_clip_preserve preserves the path within the cairo context. The current clip region affects all drawing operations by effectively masking out any changes to the surface that are outside the current clip region. Calling `cairo-clip' can only make the clip region smaller, never larger. But the current clip is part of the graphics state, so a temporary restriction of the clip region can be achieved by calling `cairo-clip' within a `cairo-save'/`cairo-restore' pair. The only other means of increasing the size of the clip region is `cairo-reset-clip'. cr a cairo context This documentation was automatically generated. cairo-clip-extents - Function: cairo-clip-extents (CR `') ==>(X1 `')(Y1 `')(X2 `')(Y2 `') Computes a bounding box in user coordinates covering the area inside the current clip. cr a cairo context x1 left of the resulting extents y1 top of the resulting extents x2 right of the resulting extents y2 bottom of the resulting extents Since 1.4 This documentation was automatically generated. cairo-reset-clip - Function: cairo-reset-clip (CR `') Reset the current clip region to its original, unrestricted state. That is, set the clip region to an infinitely large shape containing the target surface. Equivalently, if infinity is too hard to grasp, one can imagine the clip region being reset to the exact bounds of the target surface. Note that code meant to be reusable should not call `cairo-reset-clip' as it will cause results unexpected by higher-level code which calls `cairo-clip'. Consider using `cairo-save' and `cairo-restore' around `cairo-clip' as a more robust means of temporarily restricting the clip region. cr a cairo context This documentation was automatically generated. cairo-copy-clip-rectangle-list - Function: cairo-copy-clip-rectangle-list (CR `') ==>(RET `') Gets the current clip region as a list of rectangles in user coordinates. Never returns ``#f''. The status in the list may be CAIRO_STATUS_CLIP_NOT_REPRESENTABLE to indicate that the clip region cannot be represented as a list of user-space rectangles. The status may have other values to indicate other errors. The caller must always call cairo_rectangle_list_destroy on the result of this function. cr a cairo context ret the current clip region as a list of rectangles in user coordinates. Since 1.4 This documentation was automatically generated. cairo-fill - Function: cairo-fill (CR `') A drawing operator that fills the current path according to the current fill rule, (each sub-path is implicitly closed before being filled). After cairo_fill, the current path will be cleared from the cairo context. See `cairo-set-fill-rule' and `cairo-fill-preserve'. cr a cairo context This documentation was automatically generated. cairo-fill-preserve - Function: cairo-fill-preserve (CR `') A drawing operator that fills the current path according to the current fill rule, (each sub-path is implicitly closed before being filled). Unlike `cairo-fill', cairo_fill_preserve preserves the path within the cairo context. See `cairo-set-fill-rule' and `cairo-fill'. cr a cairo context This documentation was automatically generated. cairo-fill-extents - Function: cairo-fill-extents (CR `') ==>(X1 `')(Y1 `')(X2 `')(Y2 `') Computes a bounding box in user coordinates covering the area that would be affected by a `cairo-fill' operation given the current path and fill parameters. If the current path is empty, returns an empty rectangle (0,0, 0,0). Surface dimensions and clipping are not taken into account. See `cairo-fill', `cairo-set-fill-rule' and `cairo-fill-preserve'. cr a cairo context x1 left of the resulting extents y1 top of the resulting extents x2 right of the resulting extents y2 bottom of the resulting extents This documentation was automatically generated. cairo-in-fill - Function: cairo-in-fill (CR `')(X `')(Y `') ==>(RET `') Tests whether the given point is inside the area that would be affected by a `cairo-fill' operation given the current path and filling parameters. Surface dimensions and clipping are not taken into account. See `cairo-fill', `cairo-set-fill-rule' and `cairo-fill-preserve'. cr a cairo context x X coordinate of the point to test y Y coordinate of the point to test ret A non-zero value if the point is inside, or zero if outside. This documentation was automatically generated. cairo-mask - Function: cairo-mask (CR `')(PATTERN `') A drawing operator that paints the current source using the alpha channel of PATTERN as a mask. (Opaque areas of PATTERN are painted with the source, transparent areas are not painted.) cr a cairo context pattern a `' This documentation was automatically generated. cairo-mask-surface - Function: cairo-mask-surface (CR `')(SURFACE `')(SURFACE-X `')(SURFACE-Y `') A drawing operator that paints the current source using the alpha channel of SURFACE as a mask. (Opaque areas of SURFACE are painted with the source, transparent areas are not painted.) cr a cairo context surface a `' surface-x X coordinate at which to place the origin of SURFACE surface-y Y coordinate at which to place the origin of SURFACE This documentation was automatically generated. cairo-paint - Function: cairo-paint (CR `') A drawing operator that paints the current source everywhere within the current clip region. cr a cairo context This documentation was automatically generated. cairo-paint-with-alpha - Function: cairo-paint-with-alpha (CR `')(ALPHA `') A drawing operator that paints the current source everywhere within the current clip region using a mask of constant alpha value ALPHA. The effect is similar to `cairo-paint', but the drawing is faded out using the alpha value. cr a cairo context alpha alpha value, between 0 (transparent) and 1 (opaque) This documentation was automatically generated. cairo-stroke - Function: cairo-stroke (CR `') A drawing operator that strokes the current path according to the current line width, line join, line cap, and dash settings. After cairo_stroke, the current path will be cleared from the cairo context. See `cairo-set-line-width', `cairo-set-line-join', `cairo-set-line-cap', `cairo-set-dash', and `cairo-stroke-preserve'. Note: Degenerate segments and sub-paths are treated specially and provide a useful result. These can result in two different situations: 1. Zero-length "on" segments set in `cairo-set-dash'. If the cap style is CAIRO_LINE_CAP_ROUND or CAIRO_LINE_CAP_SQUARE then these segments will be drawn as circular dots or squares respectively. In the case of CAIRO_LINE_CAP_SQUARE, the orientation of the squares is determined by the direction of the underlying path. 2. A sub-path created by `cairo-move-to' followed by either a `cairo-close-path' or one or more calls to `cairo-line-to' to the same coordinate as the `cairo-move-to'. If the cap style is CAIRO_LINE_CAP_ROUND then these sub-paths will be drawn as circular dots. Note that in the case of CAIRO_LINE_CAP_SQUARE a degenerate sub-path will not be drawn at all, (since the correct orientation is indeterminate). In no case will a cap style of CAIRO_LINE_CAP_BUTT cause anything to be drawn in the case of either degenerate segments or sub-paths. cr a cairo context This documentation was automatically generated. cairo-stroke-preserve - Function: cairo-stroke-preserve (CR `') A drawing operator that strokes the current path according to the current line width, line join, line cap, and dash settings. Unlike `cairo-stroke', cairo_stroke_preserve preserves the path within the cairo context. See `cairo-set-line-width', `cairo-set-line-join', `cairo-set-line-cap', `cairo-set-dash', and `cairo-stroke-preserve'. cr a cairo context This documentation was automatically generated. cairo-stroke-extents - Function: cairo-stroke-extents (CR `') ==>(X1 `')(Y1 `')(X2 `')(Y2 `') Computes a bounding box in user coordinates covering the area that would be affected by a `cairo-stroke' operation operation given the current path and stroke parameters. If the current path is empty, cr a cairo context x1 left of the resulting extents y1 top of the resulting extents x2 right of the resulting extents y2 bottom of the resulting extents This documentation was automatically generated. cairo-in-stroke - Function: cairo-in-stroke (CR `')(X `')(Y `') ==>(RET `') Tests whether the given point is inside the area that would be affected by a `cairo-stroke' operation given the current path and stroking parameters. Surface dimensions and clipping are not taken into account. See `cairo-stroke', `cairo-set-line-width', `cairo-set-line-join', `cairo-set-line-cap', `cairo-set-dash', and `cairo-stroke-preserve'. cr a cairo context x X coordinate of the point to test y Y coordinate of the point to test ret A non-zero value if the point is inside, or zero if outside. This documentation was automatically generated. cairo-copy-page - Function: cairo-copy-page (CR `') Emits the current page for backends that support multiple pages, but doesn't clear it, so, the contents of the current page will be retained for the next page too. Use `cairo-show-page' if you want to get an empty page after the emission. cr a cairo context This documentation was automatically generated. cairo-show-page - Function: cairo-show-page (CR `') Emits and clears the current page for backends that support multiple pages.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command `./configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. guile-cairo-1.10.0/cairo.scm0000664000175000017500000000305013063724072012517 00000000000000;; guile-cairo ;; Copyright (C) 2007, 2011 Andy Wingo ;; This program is free software; you can redistribute it and/or modify ;; it under the terms of the GNU Lesser General Public License as ;; published by the Free Software Foundation; either version 3 of the ;; License, or (at your option) any later version. ;; ;; This program is distributed in the hope that it will be useful, but ;; WITHOUT ANY WARRANTY; without even the implied warranty of ;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number.

A pasteable introduction to using Guile-Cairo ============================================= ;; Paste this into your guile interpreter! ;; This wrapset defines a module `(cairo)' (use-modules (cairo)) ;; Cairo procedures all start with `cairo-' (cairo-version-string) ;; => "1.14.8" ;; For most useful things, you have to make a surface first (define surf (cairo-image-surface-create 'argb32 140 100)) ;; Given a surface, you can create a cairo context, and start drawing (define cr (cairo-create surf)) ;; You then need to make a source (cairo-select-font-face cr "Bitstream Vera Sans" 'normal 'normal) (cairo-scale cr 100 100) (define pat (cairo-pattern-create-linear 0 0 1 1)) (cairo-pattern-add-color-stop-rgba pat 1 1 0 0 1) (cairo-pattern-add-color-stop-rgba pat 0 0 0 1 1) (cairo-set-source cr pat) ;; Then you make your mask (cairo-set-font-size cr 0.4) (cairo-move-to cr 0.0 0.6) (cairo-show-text cr "(cairo)") ;; Finally you can write the surface out to a file if you want (cairo-surface-write-to-png surf "/tmp/guile-cairo.png") ;; Functions that write out to files always take the filename as their ;; last argument, which is optional. If you leave it out, guile-cairo ;; will write to the current output port. So this is another way of ;; doing the same thing: (with-output-to-file "/tmp/guile-cairo.png" (lambda () (cairo-surface-write-to-png surf))) ;; Enumerated types are represented as symbols. The available set of ;; symbols for any given type can be retrieved at runtime (cairo-format-get-values) ;; => (argb32 rgb24 a8 a1) ;; That's it! Notes ===== Guile-Cairo wraps almost all of Cairo's procedures. Notable exceptions include functions that read or write from streams instead of files and raw access to image data. Guile-Cairo wraps all of Cairo's types. As mentioned above, enumerated values are represented by symbols, but functions accept integers as well. Struct types like cairo_rectangle_t are represented as vectors. Constructors of the form cairo-make-rectangle are provided, as well as accessors like cairo-rectangle:x. Using Guile-Cairo's C interface =============================== These days Cairo forms a part of many software stacks; its types are seen in the APIs of a number of other libraries. Guile-Cairo provides an interface to represent all cairo C types as scheme values. To build against this library in your C program, first you will need to get the CFLAGS and LDFLAGS to link against libguile-cairo. Autoconf users should use: PKG_CHECK_MODULES(GUILE_CAIRO, guile-cairo >= 1.3.0) AC_SUBST(GUILE_CAIRO_CFLAGS) AC_SUBST(GUILE_CAIRO_LDFLAGS) In your C files you should then: #include The type wrapping functions are all in the form scm_to_TYPE and scm_from_TYPE, where TYPE could be cairo_surface, for example. For vector types there is also scm_fill_TYPE, which expects you to have an already-allocated structure to fill. Additionally there are scm_take_TYPE functions that will take ownership of the pointer in question, for example for constructors and for non-refcounted opaque objects like cairo_font_options_t. Known bugs ================== [https://bugs.freedesktop.org/show_bug.cgi?id=30510] Reported by CK Jester-Young The documentation for cairo-pdf-surface-create specifies the arguments as (filename width-in-points height-in-points). In actuality, it's (sx sy [filename]), where an unspecified filename means the output is sent to the current output port. This bug hasn't been fixed because of inability to regenerate the documentation. Any help in this sense is appreciated.
