Each operation can be individually controlled and turned on or off. The principal use of \fBmkbitmap\fP is to convert color or greyscale images into a format suitable as input for other programs, particularly the tracing program \fBpotrace\fP(1). It is particularly useful for converting scanned line art, such as cartoons, handwritten text, etc., to high-resolution bilevel images. \fIHighpass filtering\fP can be used to ensure that foreground features such as lines and text are preserved, while at the same time compensating for uneven background. Optional \fIblurring\fP can be applied to smooth out the image and remove visual noise. \fIScaling\fP is important because a scanned greyscale image contains more visual detail than a bilevel image at the same resolution. By scaling the image to a higher resolution (using interpolation) before thresholding it, some of this detail is preserved. \fIThresholding\fP means converting a greyscale image to a bilevel image using only black and white pixels. Pixels that are darker than a certain threshold value are converted to black. Optional \fIinversion\fP is useful if the input image shows bright features on dark background, such as a picture of chalk drawings on a blackboard. Supported input formats are PNM (PBM, PGM, PPM) and BMP. The output formats are PBM for bitmaps, and PGM for greymaps. .SH OPTIONS .SS General options: .TP 15 .B -h, --help print help message and exit. .TP .B -v, --version print version info and exit. .TP .B -l, --license print license info and exit. .PD .SS Input/output options: .TP 15 .B \fIfilename\fP If filename arguments are given, then \fBmkbitmap\fP will by default create one output file for each input filename given. The name of the output file is obtained from the input filename by changing its suffix to ".pbm" or ".pgm". If the name of the input file and output file would be identical, then an additional suffix "-out" is appended to the output filename. If no filename arguments are given, then \fBmkbitmap\fP acts as a filter, reading from standard input and writing to standard output. A filename of "-" may be given to specify reading from standard input; the output for this argument will then be written to standard output. Each input file may contain one or more images. .TP .B -o \fIfilename\fP, --output \fIfilename\fP write output to this file. All output is concatenated and directed to the specified file. This overrides the default behavior of creating one output file for each input file. A filename of "-" may be given to specify writing to standard output. .PD .SS Image processing options: .TP 15 .B -x, --nodefaults Turn off default options. Normally, the following options are preselected by default: \fB-f 4 -s 2 -3 -t 0.45\fP. The \fB-x\fP option disables these defaults; thus, \fBmkbitmap -x\fP does nothing but copy a greyscale image from the input to the output. Other processing options can then be added one by one; e.g., \fBmkbitmap -xf10\fP does only highpass filtering, \fBmkbitmap -xt0.5\fP does only thresholding, etc. .TP .B -i, --invert Invert the input image. If this option is chosen, it is applied to the image before any other operation. It is used to deal with white-on-black images, such as photographs of chalk drawings on a blackboard. Note that the behavior of this option is not in general the same as inverting the \fIoutput\fP bitmap, unless the thresholding value is also inverted. .TP .B -f \fIn\fP, --filter \fIn\fP Apply a highpass filter to the image. This filter is approximately Gaussian and non-directional. The effect is to preserve small detail while compensating for background gradients. The parameter \fIn\fP is a radius (in pixels) which corresponds approximately to the size of details which should be preserved. More precisely, the filter is implemented by subtracting a blurred version of the image from the original image. The parameter \fIn\fP is equal to the standard deviation of the blur. The output of the filtering step is a normalized image whose average brightness is exactly 0.5. The default filter radius is 4. .TP .B -n, --nofilter Turn off highpass filtering. .TP .B -b \fIn\fP, --blur \fIn\fP Blur the image. The effect is to smooth out fine details and to reduce visual noise in the image. The parameter \fIn\fP is the blurring radius, and should be chosen small (1 is a good value to start with). This is implemented as an approximately Gaussian, non-directional blur with standard deviation proportional to \fIn\fP. Blurring is applied after the highpass filter, but before scaling and thresholding. If this option is not given, the default is not to apply any blurring. .TP .B -s \fIn\fP, --scale \fIn\fP Scale the image by an integer factor \fIn\fP>0. Scaling is done after highpass filtering, but before the thresholding step. A scaling factor of 1 indicates that no scaling is to be done. Otherwise, interpolation is used to fill in the in-between pixels. If the output of \fBmkbitmap\fP is to be used as input to a tracing program such as \fBpotrace\fP, a scaling factor of 2 is recommended. This preserved the right amount of detail for the tracing algorithm to work well. If a scaling factor of 1 is used, too much detail is lost. If a scaling factor of 3 or higher is used, the interpolation tends to "invent" detail which was not present in the original image, thus preventing \fBpotrace\fP from doing a good job. .TP .B -1, --linear Use linear interpolation when scaling to a higher resolution. This is slightly faster, but less nice, than the default cubic interpolation. .TP .B -3, --cubic Use cubic interpolation when scaling to a higher resolution. This is the default. It is slower than linear interpolation, but leads to better results. .TP .B -t \fIn\fP, --threshold \fIn\fP Set the threshold grey value for bilevel conversion. The parameter \fIn\fP is a brightness value between 0 for black and 1 for white. Any pixels below this brightness will be converted to black (thus, smaller values of \fIn\fP will lead to whiter output). .TP .B -g, --grey Disable bilevel conversion. If this option is given, processing stops after the scaling step and a greymap is output. .PD .SH EXIT STATUS The exit status is 0 on successful completion, 1 if the command line was invalid, and 2 on any other error. .SH VERSION @VERSION@ .SH AUTHOR Peter Selinger .SH WEB SITE AND SUPPORT \fBmkbitmap\fP is distributed as part of the \fBpotrace\fP package, and the latest version is available from http://potrace.sourceforge.net/.

The input is a bitmap, which means, a pixel-based image composed of the two colors black and white only. The output is EPS, PDF, SVG, or one of a number of other vector formats. A typical use is to create vector graphics from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not "jaggy" like a bitmap, but smooth. It can then be rendered at any resolution. \fBpotrace\fP can read bitmaps in the following formats: PBM, PGM, PPM (collectively known as PNM, see pnm(5)), as well as BMP (Windows and OS/2 bitmap formats). The input image should only use the two colors black and white. If other pixel values appear in the input, they will be converted to black and white using a simple threshold method. \fBpotrace\fP can currently produce the following output formats: EPS, PostScript, PDF, SVG, DXF, GeoJSON, PGM, Gimppath, and XFig. Additional backends might be added in the future. .SH OPTIONS The following options are supported. Dimensions (arguments of type \fIdim\fP) can have optional units, e.g. 6.5in, 15cm, 100pt. The default unit is inches (or centimeters, if this was configured at compile time, see COMPILE TIME CONFIGURATION below). For pixel-based output formats such as PGM, DXF, GeoJSON, and Gimppath, the default unit is pixels. .SS General options: .TP 15 .B -h, --help print help message and exit. .TP .B -v, --version print version info and exit. This also shows the defaults that were compiled into this version of \fBpotrace\fP. .TP .B -l, --license print license info and exit. .PD .SS Input/output options: .TP 15 .B \fIfilename\fP Each file can hold an input image, or multiple concatenated input images. If filename arguments are given, then \fBpotrace\fP will by default create one output file for each input filename given. The name of the output file is obtained from the input filename by changing its suffix according to the chosen backend. If changing the suffix is impossible because the names of the input and output files would be identical, then the output filename is created by adding the "-out" suffix to the name of the input file. If no filename arguments are given, then \fBpotrace\fP acts as a filter, reading from standard input and writing to standard output. A filename of "-" may be given to specify reading from standard input. .TP .B -o \fIfilename\fP, --output \fIfilename\fP write output to this file. All output is directed to the specified file. If this option is used, then multiple input filenames are only allowed for multi-page backends (see BACKEND TYPES below). In this case, each input file may contain one or more bitmaps, and all the bitmaps from all the input files are processed and the output concatenated into a single file. A filename of "-" may be given to specify writing to standard output. .TP .B -- End of options. Any remaining arguments are interpreted as filenames. This also disables filter mode, even if no filenames are given. This is useful for shell scripts, because \fBpotrace -- $FILENAMES\fP will behave correctly even for an empty list of filenames. However, \fB--\fP with an empty list of filenames is not permitted in conjunction with the \fB-o\fP option, because this would generate a document of zero pages, which none of the backends permit. .PD .SS Backend selection: For general information, see also BACKEND TYPES below. .TP 15 .B -b \fIname\fP, --backend \fIname\fP Select backend by name, where \fIname\fP is one of eps, postscript, ps, pdf, pdfpage, svg, dxf, geojson, pgm, gimppath, xfig. Backend names can be abbreviated by a prefix as long as it is unambiguous. Backend names are case insensitive. .TP .B -e, --eps, -b eps, --backend eps EPS backend (default). The output is an encapsulated PostScript file. This is a single-page, variable-sized, dimension-based backend. .TP .B -p, --postscript, -b ps, --backend ps PostScript backend. The output is a PostScript file. This is a multi-page, fixed-size, dimension-based backend. If the input consists of multiple bitmaps, they are each rendered on a separate page. .TP .B -b pdf, --backend pdf PDF backend. The output is a file in the Portable Document Format. If the input consists of multiple bitmaps, they are each rendered on a separate page. This is a multi-page, variable-sized, dimension-based backend. .TP .B -b pdfpage, --backend pdfpage The PDFPage backend is like the PDF backend, except that it is fixed-size like the PostScript backend. .TP .B -s, --svg, -b svg, --backend svg SVG backend. The output is a Scalable Vector Graphics (SVG) file. This is a single-page, variable-sized, dimension-based backend. Note that unless the \fB-r\fP option is given, the resolution of the input bitmap is assumed to be 72dpi. .TP .B -b dxf, --backend dxf DXF backend. The output is a file in the Drawing Interchange Format (DXF). In this backend, all Bezier curves are approximated by piecewise circular arcs; this is suitable for processing in CAD software or for machining applications using CNC tools. This is a single-page, variable-sized, pixel-based backend. The \fB-u\fP option has no effect for this backend. .TP .B -b geojson, --backend geojson GeoJSON backend. The output is a file in the format used by some applications processing geographical data. In this backend, all Bezier curves are approximated by 8 straight line segments. This is a single-page, variable-sized, pixel-based backend. The \fB-u\fP option has no effect for this backend. .TP .B -g, --pgm, -b pgm, --backend pgm PGM backend. The output is a portable greymap (PGM) file. It is a convenient backend for antialiasing a bitmap image. This is a multi-page, variable-sized, pixel-based backend. If the input consists of more than one image, the images are concatenated in the output. .TP .B -b gimppath, --backend gimppath Gimppath backend. This backend produces output suitable to be imported as a path by the GNU Image Manipulation Program (Gimp) (in the Layers, Channels & Paths dialog, select Paths, then right-click and select Import Path). The output is actually an SVG file. The differences to the SVG backend are: the \fB--opaque\fP option has no effect, the \fB--flat\fP option is always on, and the dimensions are pixel-based. This is a single-page, variable-sized, pixel-based backend. .TP .B -b xfig, --backend xfig XFig backend. This is a single-page, fixed-size, dimension-based backend. The output is a file in the XFig format. Note that XFig uses X-splines instead of Bezier curves, thus it is not possible to translate the output of \fBpotrace\fP into the XFig format with absolute accuracy. This backend does a reasonable approximation using two control points for each Bezier curve segment. The \fB-u\fP option has no effect for this backend, because control points are always rounded to the nearest 1/1200 of an inch in XFig. Curve optimization is disabled. Implies \fB--opaque\fP. .PD .SS Algorithm options: For more detailed information on these options, see TECHNICAL DOCUMENTATION below. .TP 15 .B -z \fIpolicy\fP, --turnpolicy \fIpolicy\fP specify how to resolve ambiguities in path decomposition. Must be one of black, white, right, left, minority, majority, or random. Default is minority. Turn policies can be abbreviated by an unambiguous prefix, e.g., one can specify min instead of minority. .TP .B -t \fIn\fP, --turdsize \fIn\fP suppress speckles of up to this many pixels. .TP .B -a \fIn\fP, --alphamax \fIn\fP set the corner threshold parameter. The default value is 1. The smaller this value, the more sharp corners will be produced. If this parameter is 0, then no smoothing will be performed and the output is a polygon. If this parameter is greater than 4/3, then all corners are suppressed and the output is completely smooth. .TP .B -n, --longcurve turn off curve optimization. Normally \fBpotrace\fP tries to join adjacent Bezier curve segments when this is possible. This option disables this behavior, resulting in a larger file size. .TP .B -O \fIn\fP, --opttolerance \fIn\fP set the curve optimization tolerance. The default value is 0.2. Larger values allow more consecutive Bezier curve segments to be joined together in a single segment, at the expense of accuracy. .TP .B -u \fIn\fP, --unit \fIn\fP set output quantization. Coordinates in the output are rounded to 1/unit pixels. The default of 10 usually gives good results. For some of the debug modes, a value of 100 gives more accurate output. This option has no effect for the XFig backend, which always rasterizes to 1/1200 inch, or for the DXF backend. For the GeoJSON backend, this option is only a hint; the actual rounding may be more, but not less, accurate than specified. .TP .B -d \fIn\fP, --debug \fIn\fP produce debugging output of type n. This has different effects for different backends. For the PostScript/EPS backends, the values n=1,2,3 illustrate the intermediate stages of the \fBpotrace\fP algorithm. .PD .SS Scaling and placement options: .TP 15 .B -P \fIformat\fP, --pagesize \fIformat\fP for fixed-size backends, set page size. The following formats can be specified: A4, A3, A5, B5, Letter, Legal, Tabloid, Statement, Executive, Folio, Quarto, 10x14. Format names are case insensitive. Also, an argument of the form \fIdim\fPx\fIdim\fP is accepted to specify arbitrary dimensions. The default page size is Letter (or A4, if this was configured at compile time, see COMPILE TIME CONFIGURATION below). Page format names can be abbreviated by a prefix as long as it is unambiguous. This option has no effect for variable-sized backends. .TP .B -W \fIdim\fP, --width \fIdim\fP set the width of output image (before any rotation and margins). If only one of width and height is specified, the other is adjusted accordingly so that the aspect ratio is preserved. .TP .B -H \fIdim\fP, --height \fIdim\fP set the height of output image. See \fB-W\fP for details. .TP .B -r \fIn\fP[x\fIn\fP], --resolution \fIn\fP[x\fIn\fP] for dimension-based backends, set the resolution (in dpi). One inch in the output image corresponds to this many pixels in the input. Note that a larger value results in a smaller output image. It is possible to specify separate resolutions in the x and y directions by giving an argument of the form \fIn\fPx\fIn\fP. For variable-sized backends, the default resolution is 72dpi. For fixed-size backends, there is no default resolution; the image is by default scaled to fit on the page. This option has no effect for pixel-based backends. If \fB-W\fP or \fB-H\fP are specified, they take precedence. .TP .B -x \fIn\fP[x\fIn\fP], --scale \fIn\fP[x\fIn\fP] for pixel-based backends, set the scaling factor. A value greater than 1 enlarges the output, a value between 0 and 1 makes the output smaller. The default is 1. It is possible to specify separate scaling factors for the x and y directions by giving an argument of the form \fIn\fPx\fIn\fP. This option has no effect for dimension-based backends. If \fB-W\fP or \fB-H\fP are specified, they take precedence. .TP .B -S \fIn\fP, --stretch \fIn\fP set the aspect ratio. A value greater than 1 means the image will be stretched in the y direction. A value between 0 and 1 means the image will be compressed in the y direction. .TP .B -A \fIangle\fP, --rotate \fIangle\fP set the rotation angle (in degrees). The output will be rotated counterclockwise by this angle. This is useful for compensating for images that were scanned not quite upright. .TP .B -M \fIdim\fP, --margin \fIdim\fP set all four margins. The effect and default value of this option depend on the backend. For variable-sized backends, the margins will simply be added around the output image (or subtracted, in case of negative margins). The default margin for these backends is 0. For fixed-size backends, the margin settings can be used to control the placement of the image on the page. If only one of the left and right margin is given, the image will be placed this distance from the respective edge of the page, and similarly for top and bottom. If margins are given on opposite sides, the image is scaled to fit between these margins, unless the scaling is already determined explicitly by one or more of the \fB-W\fP, \fB-H\fP, \fB-r\fP, or \fB-x\fP options. By default, fixed-size backends use a non-zero margin whose width depends on the page size. .TP .B -L \fIdim\fP, --leftmargin \fIdim\fP set the left margin. See \fB-M\fP for details. .TP .B -R \fIdim\fP, --rightmargin \fIdim\fP set the right margin. See \fB-M\fP for details. .TP .B -T \fIdim\fP, --topmargin \fIdim\fP set the top margin. See \fB-M\fP for details. .TP .B -B \fIdim\fP, --bottommargin \fIdim\fP set the bottom margin. See \fB-M\fP for details. .TP .B --tight remove whitespace around the image before scaling and margins are applied. If this option is given, calculations of the width, height, and margins are based on the actual vector outline, rather than on the outer dimensions of the input pixmap, which is the default. In particular, the \fB--tight\fP option can be used to remove any existing margins from the input image. See the file placement.pdf for a more detailed illustration. .PD .SS Color options: These options are only supported by certain backends. The DXF and GeoJSON backends do not support color. .TP 15 .B -C \fI#rrggbb\fP, --color \fI#rrggbb\fP set the foreground color of the output image. The default is black. .TP .B --fillcolor \fI#rrggbb\fP set the fill color of the output image, i.e., the color of the "white" parts that are enclosed by "black" parts. The default is to leave these parts transparent. Implies \fB--opaque\fP. Please note that this option sets the background color; to set the foreground color, use \fB--color\fP instead. .TP .B --opaque fill in the white parts of the image opaquely, instead of leaving them transparent. This only applies to interior white parts, i.e., those that are enclosed inside a black outline. Opaqueness is always in effect for the XFig backend. .PD .SS SVG options: .TP 15 .B --group for SVG output, try to group related paths together. Each path is grouped together with all paths that are contained inside it, so that they can be moved around as a unit with an SVG editor. This makes coloring individual components slightly more cumbersome, and thus it is not the default. .TP .B --flat for SVG output, put the entire image into a single path. This makes it impossible to color the components individually, and thus it is not the default. But the resulting SVG file can be more easily imported by some applications such as Gimp. In fact, the Gimppath backend is a variation of the SVG backend with the \fB--flat\fP option and pixel-based scaling. The \fB--flat\fP option has no effect if \fB--opaque\fP has been selected. .PD .SS PostScript/EPS/PDF options: .TP 15 .B -c, --cleartext do not compress the output. This option disables the use of compression filters in the PostScript and PDF output. In the PostScript backend, if \fB-c\fP and \fB-q\fP are used together, the resulting output can be easily read by other programs or even by humans. .TP .B -2, --level2 use PostScript level 2 compression (default). The resulting file size is ca. 40% smaller than if the \fB-c\fP option is used. .TP .B -3, --level3 use PostScript level 3 compression, if available. This gives slightly smaller files than using \fB-2\fP, but the resulting files may not print on older PostScript level 2 printers. If support for PostScript level 3 compression has been disabled at compile time, a warning message is printed and level 2 compression is used instead. .TP .B -q, --longcoding turn off optimized numerical coding in PostScript output. Normally, \fBpotrace\fP uses a very compact numerical format to represent Bezier curves in PostScript, taking advantage of existing redundancy in the curve parameters. This option disables this behavior, resulting in longer, but more readable output (particularly if the \fB-c\fP option is also used). .PD .SS PGM options: .TP 15 .B -G \fIn\fP, --gamma \fIn\fP set the gamma value for anti-aliasing (default is 2.2). Most computer displays do not render shades of grey linearly, i.e., a grey value of 0.5 is not displayed as being exactly half-way between black and white. The gamma parameter corrects for this, and therefore leads to nicer looking output. The default value of 2.2 is appropriate for most normal CRT displays. .PD .SS Frontend options: .TP 15 .B -k \fIn\fP, --blacklevel \fIn\fP set the threshold level for converting input images to bitmaps. The \fBpotrace\fP algorithm expects a bitmap, thus all pixels of the input images are converted to black or white before processing begins. Pixels whose brightness is less than \fIn\fP are converted to black, all other pixels to white. Here \fIn\fP is a number between 0 and 1. One case is treated specially: if the input is in an indexed color format with exactly 2 colors, then the blacklevel is ignored and the darker of the two colors is mapped to black. Note: the method used by \fBpotrace\fP for converting greymaps to bitmaps is very crude; much better results can be obtained if a separate program, such as \fBmkbitmap\fP(1), is used for this purpose. In particular, \fBmkbitmap\fP(1), which is distributed with \fBpotrace\fP, has the ability to scale and interpolate the image before thresholding, which results in much better preservation of detail. .TP .B -i, --invert invert the input bitmap before processing. .PD .SS Progress bar options: .TP 15 .B --progress display a progress bar for each bitmap that is processed. This is useful for interactive use. The default behavior is not to show any progress information. .TP .B --tty \fImode\fP set the terminal mode for progress bar rendering. Possible values are "vt100", which requires a vt100-compatible terminal, and "dumb", which uses only ASCII characters. The default is system dependent. .PD .SH "BACKEND TYPES" Backends can be classified in several ways, which affects the available command line options and their behavior: .TP 5 .B Fixed-size or variable-sized: For fixed-size backends, the size of the page is always the same (for example Letter or A4, as specified at compile time or by the \fB-P\fP option). By default, the image will be centered and scaled to fit the page size. For variable-size backends, the size of the page follows the size of the image. Currently the PostScript (PS), PDFPage, and XFig backends are fixed-size, and the remaining backends are variable-size. .TP .B Dimension-based or pixel-based: In dimension-based backends, distances are measured in physical units such as inches or centimeters. In pixel-based backends, distances are measured in pixel units. The \fB-r\fP option only works for dimension-based backends, and the \fB-x\fP option only works for pixel-based backends. Currently, the DXF, PGM, Gimppath, and GeoJSON backends are pixel-based, and the remaining backends are dimension-based. Currently, all pixel-based backends are variable-sized. .TP .B Single-page or multi-page: Single-page backends can only accept a single image. Multi-page backends can accept multiple images, typically one per page of output. Currently, the PostScript (PS), PDF, PDFPage, and PGM backends are multi-page, and the remaining backends are single-page. Note that multiple input images can be read in two ways: from multiple input files (with the \fB-o\fP option), or from a single input file that holds several concatenated images. .PD .SH "COMPILE TIME CONFIGURATION" Certain aspects of the behavior of \fBpotrace\fP can be configured at compile time by passing the following options to the ./configure script. .TP 5 .B --disable-zlib compile \fBpotrace\fP without the zlib compression library. This means PostScript level 3 compression will not be available. .TP .B --enable-metric compile \fBpotrace\fP with centimeters as the default unit instead of inches. .TP .B --enable-a4 compile \fBpotrace\fP with A4 as the default page size. .PD .SH "EXIT STATUS" The exit status is 0 on successful completion, 1 if the command line was invalid, and 2 on any other error. .SH VERSION @VERSION@ .SH AUTHOR Peter Selinger Please see the file AUTHORS for a full list of other contributors. .SH "TECHNICAL DOCUMENTATION" For a detailed technical description of the \fBpotrace\fP algorithm, see the file potrace.pdf, which is available from the \fBpotrace\fP web site.

This file is part of Potrace. It is licensed under the GNU General Public License. See the file COPYING for details. } \section{Scope} The Potrace library provides: \begin{itemize} \item tracing, i.e., conversion of bitmaps to a vector representation (Bezier curves and straight line segments). \end{itemize} It does not provide frontend functionality such as: \begin{itemize} \item preparation of bitmaps (e.g.\ reading a bitmap from a file, preparing a bitmap by thresholding/scaling/filtering a greyscale image etc) \end{itemize} And it does not provide backend functionality such as: \begin{itemize} \item post-processing of the vector representation (e.g.\ conversion to a file format such as PostScript or SVG, scaling + rotation, quantization etc). \end{itemize} \section{Data representation} \subsection{Bitmaps}\label{ssec-bitmap} \subsubsection{Coordinate system} \begin{figure}[t] \[ \includegraphics*[0in,0in][3in,1.7in]{potracelib-fig3} \] \caption{The Potrace coordinate system}\label{fig-coord} \end{figure} For Potrace, a bitmap of size $w\times h$ is embedded in a cartesian coordinate system where each pixel takes up the space of one unit square. The pixels are positioned so that the {\em corners} of pixels (and not their centers) lie at points with integer coordinates, as illustrated in Figure~\ref{fig-coord}. The origin of the coordinate system is at the {\em lower left} corner of the bitmap. The four corners of the bitmaps have coordinates $(0,0)$, $(0,h)$, $(w,h)$, and $(w,0)$. Sometimes we need to refer to a specific pixel (as opposed to a point in the plane). When we speak of ``pixel $[i,j]$'', we mean the pixel whose corners have coordinates $(i,j)$, $(i,j+1)$, $(i+1,j+1)$, $(i+1,j)$ in Potrace's coordinate system. Thus, pixel $[i,j]$ is the pixel whose center is at coordinates $(i+0.5, j+0.5)$. To avoid confusion, we use square brackets to refer to the pixel $[i,j]$, and round brackets to refer to the point $(i,j)$. \subsubsection{Bitmap representation} The Potrace library expects bitmaps in the following format, defined in potracelib.h: \begin{verbatim} struct potrace_bitmap_s { int w, h; /* width and height, in pixels */ int dy; /* scanline offset in words */ potrace_word *map; /* pixel data, dy*h words */ }; typedef struct potrace_bitmap_s potrace_bitmap_t; \end{verbatim} Here, \verb!potrace_word! is an unsigned integer type defined in potracelib.h. It is usually equal to a native machine word (i.e., 32 bits on a 32-bit architecture). In the following explanation, we assume that the type \verb!potrace_word! holds $N$ bits. A bitmap of dimensions $w\times h$ is divided, bottom to top, into $h$ horizontal scanlines. Each scanline is divided, left to right, into blocks of $N$ pixels. Each such block of $N$ pixels is stored as a single \verb!potrace_word!, with the leftmost pixels of the block corresponding to the most significant bit of the word, and the rightmost pixel of the block corresponding to the least significant bit of the word. Pixels that are ``on'' (or ``black'' or ``foreground'') are represented by bit value $1$. Pixels that are ``off'' (of ``white'' or ``background'') are represented by bit value $0$. If the number of bits in a scanline is not divisible by $N$, then the rightmost word of the scanline is padded on the right with zeros. The data for scanline $0$ (the bottom-most scanline) begins at \verb!map[0]!. The data for scanline $1$ begins at \verb!map[dy]!. The data for scanline $2$ begins at \verb!map[2*dy]!, and so forth. Note that $dy$ can be either positive or negative, depending on how an application wishes to lay out the image data in memory. In summary, the pixel with coordinates $[i,j]$ can be accessed by the following C formula: {\small \begin{verbatim} pixel(i,j) = ((map + j*dy)[i/N] & (1 << (N-1-i%N)) ? 1 : 0. \end{verbatim} } \subsubsection{Example} \begin{figure} \[\includegraphics{potracelib-fig2}\] \caption{Sample bitmap}\label{fig-bitmap} \begin{verbatim} w = 36; h = 12; dy = 2; map[22] = 0xfff0fc02; map[23] = 0x00000000; map[20] = 0x7ff1fe02; map[21] = 0x00000000; map[18] = 0x3ff3ff07; map[19] = 0x00000000; map[16] = 0x1ff7ff87; map[17] = 0x00000000; map[14] = 0x0ff7cf8f; map[15] = 0x80000000; map[12] = 0x07f7878f; map[13] = 0x80000000; map[10] = 0x03f7879f; map[11] = 0xc0000000; map[8] = 0x01f7cf9f; map[9] = 0xc0000000; map[6] = 0x00f7ffbf; map[7] = 0xe0000000; map[4] = 0x0073ff3f; map[5] = 0xe0000000; map[2] = 0x0031fe7f; map[3] = 0xf0000000; map[0] = 0x0010fc7f; map[1] = 0xf0000000; \end{verbatim} \caption{Sample bitmap representation}\label{fig-bitmap-rep} \end{figure} Figure~\ref{fig-bitmap} shows an example bitmap of size $36\times 12$. Shaded pixels are ``on'' and white pixels are ``off''. Figure~\ref{fig-bitmap-rep} shows a possible representation of this bitmap in the \verb!potrace_bitmap_t! data structure. Note that the data is stored in the \verb!map! array in a bottom-to-top and left-to-right fashion. \subsubsection{A remark on byte order} It is important to keep in mind that bitmaps are stored as arrays of words, {\em not} as arrays of bytes. While this distinction makes no difference on big-endian architectures, it makes a significant difference on little-endian architectures such as the Intel-based architecture. For instance, when the integer word 0x1f80fc02 is accessed as a byte-array on a little-endian machine, then the bytes appear in reverse order 0x02, 0xfc, 0x80, 0x1f. Therefore, special care must be taken when converting a bitmap from a byte-based format to Potrace's word-based format. \subsubsection{Coordinate independence} The vector data that is the output of Potrace is taken with respect to the same coordinate system as the input bitmap, i.e., the coordinate system from Figure~\ref{fig-coord}. In principle, it is immaterial whether an application puts the coordinate origin in the bottom-left corner or the top-left corner of an image, as long as it interprets the output coordinates in the same way as the input coordinates. However, a reversal of the coordinate system will upset the meaning of the words ``clockwise'' and ``counterclockwise'' in the specification of vector images below (see Section~\ref{sssec-vector}), and will also affect the meaning of Potrace's turnpolicies (see Section~\ref{ssec-parameters}). We therefore assume, for definiteness, that the coordinate origin is in the {\em lower} left corner. Applications that wish to follow a different convention have to compensate accordingly. \subsection{Vector format} \subsubsection{Points} A point $(x,y)$ in the Euclidean plane is represented in Potrace by a value of type \verb!potrace_dpoint_t!. \begin{verbatim} struct potrace_dpoint_s { double x, y; }; typedef struct potrace_dpoint_s potrace_dpoint_t; \end{verbatim} \subsubsection{Segments} Curves in Potrace are composed of the following two types of segments: \begin{figure} \[\begin{array}{l@{\hspace{1in}}l} (a) & (b) \\ \includegraphics{potracelib-fig4a}& \includegraphics{potracelib-fig4b} \end{array} \] \caption{(a) A Bezier curve segment. (b) A corner segment}\label{fig-segment} \end{figure} \begin{itemize} \item Bezier curve segments. A Bezier curve segment is given in the usual way by a starting point $a$, two control points $u$ and $w$, and an endpoint $b$, as shown in Figure~\ref{fig-segment}(a). \item Corner segments. A corner segment is given by a starting point $a$, a vertex $v$, and an endpoint $b$. A corner segment is drawn as two straight lines: one from $a$ to $v$, and one from $v$ to $b$, as shown in Figure~\ref{fig-segment}(b). \end{itemize} \subsubsection{Curves}\label{sssec-curves} \begin{figure} \[\includegraphics{potracelib-fig5} \] \caption{A closed curve consisting of 4 segments}\label{fig-curve} \end{figure} A curve in Potrace is a sequence of segments, such that the endpoint of each segment coincides with the starting point of the next one. All curves in Potrace are closed, and therefore the endpoint of the final segment also coincides with the starting point of the first one. Figure~\ref{fig-curve} shows an example of a curve consisting of 4 segments: 3 Bezier curve segments and 1 corner segment. For clarity, the start- and endpoints of segments have been marked with dots ``$\bullet$''. Curves are represented as values of type \verb!potrace_curve_t!, which is defined as follows: \begin{verbatim} struct potrace_curve_s { int n; /* number of segments */ int *tag; /* array of segment types */ potrace_dpoint_t (*c)[3]; /* array of control points. */ }; typedef struct potrace_curve_s potrace_curve_t; \end{verbatim} Here $n\geq 1$ is the number of segments in the curve. For $i=0,\ldots,n-1$, $\verb!tag[i]!$ is the type of the $i$-th segment, which is \verb!POTRACE_CURVETO! for a Bezier curve segment and \verb!POTRACE_CORNER! for a corner segment. $c$ is an array of size $n\times 3$ that holds the control points of the curve segments in the following manner: \begin{itemize} \item If the $i$-th segment is a Bezier curve segment, then $\verb!c[i][0]! = u$ and $\verb!c[i][1]! = w$ are the two control points of that segment, and $\verb!c[i][2]! = b$ is its endpoint. \item If the $i$-th segment is a corner segment, then $\verb!c[i][0]!$ is unused, $\verb!c[i][1]! = v$ is the vertex of the segment, and $\verb!c[i][2]! = b$ is its endpoint. \end{itemize} Note that, since the starting point $a$ of each segment coincides with the endpoint $b$ of the preceding segment (and the starting point $a$ of the first segment coincides with the endpoint $b$ of the last segment), there is no need to store the starting points $a$ explicitly. Also, note that regardless of the type of segment, the endpoint of the $i$-th segment is $\verb!c[i][2]!$, and the starting point of the $i$-th segment is $\verb!c[i ? i-1 : n-1][2]!$. The curve from Figure~\ref{fig-curve} is therefore represented by the following data: \[\begin{array}{llll} \verb!n = 4;!\\ \verb!tag[0] = POTRACE_CURVETO;!\\ \verb!c[0][0] = !u_0\verb!;!\quad\quad\quad \verb!c[0][1] = !w_0\verb!;!\quad \verb!c[0][2] = !b_0\verb! = !a_1\verb!;!\\ \verb!tag[1] = POTRACE_CURVETO;!\\ \verb!c[1][0] = !u_1\verb!;!\quad\quad\quad \verb!c[1][1] = !w_1\verb!;!\quad \verb!c[1][2] = !b_1\verb! = !a_2\verb!;!\\ \verb!tag[2] = POTRACE_CURVETO;!\\ \verb!c[2][0] = !u_2\verb!;!\quad\quad\quad \verb!c[2][1] = !w_2\verb!;!\quad \verb!c[2][2] = !b_2\verb! = !a_3\verb!;!\\ \verb!tag[3] = POTRACE_CORNER;!\\ \verb!c[3][0] = !{\it unused}\verb!;!\quad \verb!c[3][1] = !v_3\verb!;!\quad \verb!c[3][2] = !b_3\verb! = !a_0\verb!;!\\ \end{array} \] \subsubsection{Boundary decomposition of bitonal vector images}\label{sssec-boundary} \begin{figure} \[\begin{array}{l@{\hspace{.25in}}l} (a) & (b) \\ \includegraphics{potracelib-fig1a}& \includegraphics{potracelib-fig1b} \end{array} \] \caption{(a) A vector image. (b) Its boundary decomposition.}\label{fig-vector} \end{figure} In Potrace, a bitonal (i.e. black-and-white) vector image, as in Figure~\ref{fig-vector}(a), is decomposed into a collection of closed boundary curves, shown in blue and red and labeled $A$--$I$ in Figure~\ref{fig-vector}(b). We introduce some terminology. A closed curve is {\em simple} if it does not intersect itself. Each simple closed curve, taken by itself, divides the plane into two regions, called the {\em inside} and and the {\em outside} of the curve. If $C_1$ and $C_2$ are simple closed curves, we say that $C_1$ is {\em contained} in $C_2$, written $C_1 < C_2$, if $C_1$ lies entirely within the inside of $C_2$. For example, in Figure~\ref{fig-vector}(b), the curves $B$--$E$ are contained in $A$, whereas $F$--$I$ are not. In a decomposition of a vector image as in Figure~\ref{fig-vector}, we say that a curve $C_1$ is a {\em child} of $C_2$ if $C_1 < C_2$ and there exists no other curve $C_3$ between $C_1$ and $C_2$ (i.e., no curve $C_3$ such that $C_1 < C_3 < C_2$). In this case, we also say that $C_1$ is a {\em parent} of $C_2$. Since boundary curves do not intersect, each curve has at most one parent. Two curves are said to be {\em siblings} if they are either both parentless, or else they have a parent in common. Note that the ``child'' relation naturally defines a tree structure on the set of curves (more precisely, it defines a ``forest'', since there can be more than one root). For example, in Figure~\ref{fig-vector}(b), the curve $A$ has no parent, and has children $B$ and $E$. The curve $E$ has no children, and the curve $B$ has children $C$ and $D$. $A$ and $F$ are siblings, $B$ and $E$ are siblings, and $C$ and $D$ are siblings. The curves from Figure~\ref{fig-vector}(b) form the following forest under the ``child'' relation: \begin{verbatim} A F / \ | B E G / \ | C D H | I \end{verbatim} We can assign each curve a {\em sign} by calling a curve {\em positive} if it encloses a ``foreground'' region, and {\em negative} if it encloses a ``background'' region (or ``hole''). For example, in Figure~\ref{fig-vector}(b), positive curves are shown in blue and negative curves in red. Since foreground and background regions alternate, it follows that the sign of curves also alternates, i.e., parentless curves are always positive, and all other curves have the opposite sign of their parent. It follows that, in the tree structure, curves that appear at even levels are positive and those that appear at odd levels are negative. In particular, siblings share a common sign. \subsubsection{Representation of vector images}\label{sssec-vector} In Potrace, a vector image is represented as a linked collection of zero or more structures of type \verb!potrace_path_t!, which is defined as follows: \begin{verbatim} struct potrace_path_s { int area; /* enclosed area */ int sign; /* '+' or '-' */ potrace_curve_t curve; /* vector data */ struct potrace_path_s *next; /* list structure */ struct potrace_path_s *childlist; /* tree structure */ struct potrace_path_s *sibling; /* tree structure */ struct potrace_privpath_s *priv; /* private state */ }; typedef struct potrace_path_s potrace_path_t; \end{verbatim} Each such structure holds a single curve, and the structures are linked to each other via the \verb!next!, \verb!childlist!, and \verb!sibling! pointers. \begin{itemize} \item The \verb!sign! field holds the sign of the curve (\verb!'+'! or \verb!'-'! in ASCII). \item The \verb!curve! field contains the curve's vector data as described in Section~\ref{sssec-curves}. Potrace additionally follows the convention that positive curves run counterclockwise and negative curves run clockwise; this facilitates rendering in environments (such as PostScript or PDF) that have a ``fill'' rule based on winding number. \item The \verb!area! field gives the approximate magnitude of the area enclosed by the curve. (In fact, it is the precise integer area of the original untraced ``jaggy'' curve). Some clients use this information to improve interactive rendering speeds by ignoring very small areas in a first rendering pass. See also the description of the \verb!turdsize! parameter in Section~\ref{ssec-parameters} below. \item The \verb!priv! field is used internally by Potrace, and is not accessible to applications. \item The \verb!next! field is used to link all the curves of a given vector image into a linked list. Each member points to the next one via its \verb!next! field, and the last member of the list has \verb!next==NULL!. The order of the elements of this list is unspecified, but is guaranteed to satisfy the following constraints: \begin{enumerate}\alphalabels \item outer curves appear before inner ones, so if $C_1 < C_2$, then $C_2$ always appears sometime before $C_1$ in the linked list, and \item each positive curve is immediately followed by all of its children. \end{enumerate} These two constraints make it easy for clients to render the image by simply processing the linked list in sequential order. Constraint (a) makes it possible to fill each curve with solid black or white color, allowing later curves to paint over parts of earlier ones. Constraint (b) further allows a client to fill a positive curve, minus its negative children, in a single paint operation, leaving a ``hole'' for each of the negative children. \item The \verb!childlist! and \verb!sibling! fields define a forest structure on the set of curves, which can be used independently of the linked list structure. For each curve, \verb!childlist! is a pointer to its first child, or \verb!NULL! if there are no children. Also, \verb!sibling! is a pointer to the next sibling, or \verb!NULL! if there are no further siblings. The relative order of siblings is unspecified. The root node of the tree structure always coincides with the root node of the linked list structure. \end{itemize} An image consisting of zero curves is represented as a \verb!NULL! pointer. \subsubsection{Intersecting curves} While in the above discussion we have assumed a set of non-intersecting curves, in practice it can happen that the curves output by Potrace intersect slightly. Clients should therefore carefully choose their rendering parameters (e.g., the non-zero winding number rule is preferable to the odd winding number rule) to avoid undesirable artifacts. \subsubsection{Example} The image from Figure~\ref{fig-vector} can be represented by the pointer \verb!plist!, where {\tt A}--{\tt I} are structures of type \verb!potrace_path_t!, as follows. We do not show the \verb!area! and \verb!curve! fields. {\small \begin{verbatim} potrace_path_t *plist = &A; A.sign = '+'; B.sign = '-'; E.sign = '-'; A.next = &B; B.next = &E; E.next = &C; A.childlist = &B; B.childlist = &C; E.childlist = NULL; A.sibling = &F; B.sibling = &E; E.sibling = NULL; C.sign = '+'; D.sign = '+'; F.sign = '+'; C.next = &D; D.next = &F; F.next = &G; C.childlist = NULL; D.childlist = NULL; F.childlist = &G; C.sibling = &D; D.sibling = NULL; F.sibling = NULL; G.sign = '-'; H.sign = '+'; I.sign = '-'; G.next = &H; H.next = &I; I.next = NULL; G.childlist = &H; H.childlist = &I; I.childlist = NULL; G.sibling = NULL; H.sibling = NULL; I.sibling = NULL; \end{verbatim} } \subsection{Tracing parameters}\label{ssec-parameters} The tracing operation of Potrace is controlled by a small number of parameters. The parameter structure is defined in potracelib.h as: \begin{verbatim} struct potrace_param_s { int turdsize; int turnpolicy; double alphamax; int opticurve; double opttolerance; potrace_progress_t progress; }; typedef struct potrace_param_s potrace_param_t; \end{verbatim} For most practical purposes, the default parameters give excellent results. The function \verb!potrace_param_default()! (see Section~\ref{5c}) returns the set of default parameters. Applications must always start from these default parameters before changing any parameters. This will increase backward compatibility in case additional parameters are added in the future. \subsubsection{Turdsize} \begin{figure} \[\begin{array}{l@{\hspace{.5in}}l} \textrm{\rm Before:} & \textrm{\rm After:}\\ \includegraphics{potracelib-fig6a}& \includegraphics{potracelib-fig6b} \end{array} \] \caption{Despeckling with turdsize=3.}\label{fig-turdsize} \end{figure} The \verb!turdsize! parameter can be used to ``despeckle'' the bitmap to be traced, by removing all curves whose enclosed area is below the given threshold. Figure~\ref{fig-turdsize} shows the result of applying turdsize=3 to a bitmap. The current default for the turdsize parameter is 2; its useful range is from 0 to infinity. \subsubsection{Turnpolicy} \begin{figure} \[\includegraphics{potracelib-fig8}\] \caption{Path decomposition}\label{fig-turns} \end{figure} The turnpolicy parameter determines how to resolve ambiguities during decomposition of bitmaps into paths. The ambiguity arises in the last situation shown in Figure~\ref{fig-turns}. The possible choices for the \verb!turnpolicy! parameter are: \begin{itemize} \item \verb!POTRACE_TURNPOLICY_BLACK!: prefers to connect black (foreground) components. \item \verb!POTRACE_TURNPOLICY_WHITE!: prefers to connect white (background) components. \item \verb!POTRACE_TURNPOLICY_LEFT!: always take a left turn. \item \verb!POTRACE_TURNPOLICY_RIGHT!: always take a right turn. \item \verb!POTRACE_TURNPOLICY_MINORITY!: prefers to connect the color (black or white) that occurs least frequently in a local neighborhood of the current position. \item \verb!POTRACE_TURNPOLICY_MAJORITY!: prefers to connect the color (black or white) that occurs most frequently in a local neighborhood of the current position. \item \verb!POTRACE_TURNPOLICY_RANDOM!: choose pseudo-randomly. \end{itemize} The current default policy is \verb!POTRACE_TURNPOLICY_MINORITY!, which tends to keep visual lines connected. \subsubsection{Alphamax} \begin{figure} \[\begin{array}{ccccc} \includegraphics{potracelib-fig7-00}& \includegraphics{potracelib-fig7-06}& \includegraphics{potracelib-fig7-10}& \includegraphics{potracelib-fig7-12}& \includegraphics{potracelib-fig7-13}\\ \alpha_{max}=0.0& \alpha_{max}=0.6& \alpha_{max}=1.0& \alpha_{max}=1.2& \alpha_{max}=1.3 \end{array} \] \caption{The alphamax parameter}\label{fig-alphamax} \end{figure} The \verb!alphamax! parameter is a threshold for the detection of corners. It controls the smoothness of the traced curve, as shown in Figure~\ref{fig-alphamax}. The current default is 1.0. The useful range of this parameter is from 0.0 (polygon) to 1.3334 (no corners). \subsubsection{Opticurve and opttolerance} The \verb!opticurve! parameter is a boolean flag that controls whether Potrace will attempt to ``simplify'' the final curve by reducing the number of Bezier curve segments. Opticurve=1 turns on optimization, and opticurve=0 turns it off. The current default is on. The \verb!opttolerance! parameter defines the amount of error allowed in this simplification. The current default is 0.2. Larger values tend to decrease the number of segments, at the expense of less accuracy. The useful range is from 0 to infinity, although in practice one would hardly choose values greater than 1 or so. For most purposes, the default value is a good tradeoff between space and accuracy. \subsubsection{Progress reporting} Since tracing a large bitmap can be time consuming, Potrace has the option of reporting progress to the calling application. This is typically used in interactive applications to implement a progress bar. Progress reporting is controlled by the \verb!progress! parameter, which is a structure of type \verb!potrace_progress_t!, defined as follows: \begin{verbatim} struct potrace_progress_s { void (*callback)(double progress, void *privdata); void *data; double min, max; double epsilon; }; typedef struct potrace_progress_s potrace_progress_t; \end{verbatim} If \verb!callback! is not NULL, then progress reporting is enabled. In this case, \verb!callback! is the address of a function to be called for progress reports, and \verb!data! is a pointer to that function's private data. Progress reports take the form of a function call \verb!callback(d, data)!, where \verb!d! is a number representing the amount of relative progress in the range \verb!min!\ldots\verb!max!. The parameter \verb!epsilon! is a hint that tells Potrace what amount of progress the application considers ``too small to report''. Whenever convenient, Potrace will feel free to suppress progress reports if the increment since the previous report has been less than \verb!epsilon!. As a special case, if $\verb!epsilon!=0$, then the maximal number of progress reports are sent. In any case, the application should handle progress reports very efficiently, as there may be a large number of reports. The defaults are $\verb!callback!=\textrm{NULL}$, $\verb!data!=\textrm{NULL}$, $\verb!min!=0.0$, $\verb!max!=1.0$, and $\verb!epsilon!=0$. \subsection{Potrace state}\label{4} A Potrace state holds the result of a tracing operation. It is defined as follows: \begin{verbatim} struct potrace_state_s { int status; potrace_path_t *plist; /* vector data */ struct potrace_privstate_s *priv; /* private state */ }; typedef struct potrace_state_s potrace_state_t; \end{verbatim} The fields are as follows: \begin{itemize} \item The \verb!status! field is either \verb!POTRACE_STATUS_OK!, to indicate that the tracing operation was successful, or \verb!POTRACE_STATUS_INCOMPLETE!, to indicate that it was unsuccessful. \item In the event of success, \verb!plist! points to the representation of the bitonal traced vector image as described in Section~\ref{sssec-vector}. In the event of failure, \verb!plist! points to a data structure whose properties are undefined, except that the Potrace state can still be freed with \verb!potrace_state_free()!. \item The \verb!priv! field is used internally by Potrace, and is not accessible by applications. \end{itemize} \section{API functions}\label{5} There is no global or static state in potracelib; all API functions are reentrant and thread-safe. \subsection{potrace\_trace}\label{5a} {\small \begin{verbatim} potrace_state_t *potrace_trace(const potrace_param_t *param, const potrace_bitmap_t *bm); \end{verbatim} } \noindent Inputs: \begin{itemize} \item \verb!bm!: a bitmap (see Section~\ref{ssec-bitmap}). \item \verb!param!: a set of tracing parameters (see Section~\ref{ssec-parameters}). \end{itemize} \noindent Output: \begin{itemize} \item a Potrace state (see Section~\ref{4}). \end{itemize} This function attempts to trace the given bitmap using the given tracing parameters. In the event of success, it returns a valid Potrace state with the \verb!status! field set to \verb!POTRACE_STATUS_OK!. In the event of failure, it sets \verb!errno! to an error number, and either returns \verb!NULL!, or else it returns an incomplete Potrace state, which by definition has the status field set to \verb!POTRACE_STATUS_INCOMPLETE!. Any Potrace state returned by \verb!potrace_trace()! (whether it is valid or invalid) can be freed using the \verb!potrace_state_free()! function below. \subsection{potrace\_state\_free}\label{5b} \begin{verbatim} void potrace_state_free(potrace_state_t *st); \end{verbatim} \noindent Input: \begin{itemize} \item \verb!st!: a Potrace state previously returned by \verb!potrace_trace()!. \end{itemize} This function frees the memory and other resources (if any) associated with the Potrace state. \subsection{potrace\_param\_default}\label{5c} \begin{verbatim} potrace_param_t *potrace_param_default(); \end{verbatim} \noindent Output: \begin{itemize} \item a set of tracing parameters (see Section~\ref{ssec-parameters}). \end{itemize} This function returns a fresh set of tracing parameters, initialized to defaults. Applications must always use this function to create an object of type \verb!potrace_param_t!, and they must always start from the default parameters before modifying any parameters. This will help increase backward compatibility when additional parameters are added in the future. The parameter set returned by this function can later be freed by \verb!potrace_param_free()!. \subsection{potrace\_param\_free()}\label{5d} \begin{verbatim} void potrace_param_free(potrace_param_t *p); \end{verbatim} \noindent Input: \begin{itemize} \item tracing parameters previously returned by \verb!potrace_param_default()!. \end{itemize} This function frees the memory occupied by a set of tracing parameters as returned by \verb!potrace_param_default()!. Only the fields initialized by Potrace are freed, not any fields set by the application itself (such as \verb!progress.data!). \subsection{potrace\_version()}\label{5e} \begin{verbatim} const char *potrace_version(); \end{verbatim} This function returns a static human-readable text string identifying this version of potracelib. \end{document} potrace-1.14/README0000664000175000017500000001753413052220554010707 00000000000000 POTRACE - transform bitmaps into vector graphics * * * DESCRIPTION Potrace is a tool for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP), and the default output is one of several vector file formats. A typical use is to create EPS files from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not "jaggy" like a bitmap, but smooth. It can then be rendered at any resolution. Potrace can currently produce the following output formats: EPS, PostScript, PDF, SVG (scalable vector graphics), DXF, GeoJSON, PGM (for easy antialiasing of pixel-based images), Gimppath, and XFig. Additional backends might be added in the future. A separate program, mkbitmap, is also provided. This program can act as a pre-processor for Potrace, applying scaling and various filters to an image before converting it to a bitmap. This is useful for potracing greyscale and color images. DEPENDENCIES Potrace relies on the zlib library for PostScript level 3 compression. This library is pre-installed on most modern systems. If not present, it can be obtained from http://www.gzip.org/zlib/. COMPILATION For generic compilation instructions, see the file INSTALL. In addition, the following compile time options (options to ./configure) are supported. --with-libpotrace install Potrace library and headers (default: no) --disable-zlib disable PostScript level 3 compression --enable-metric use metric units (centimeters) as default --enable-a4 use a4 as the default papersize --enable-dumb-tty use simplified ASCII-only progress bar See also ./configure --help. INSTALLING If you are installing from sources, just do "make install" as root. If you are installing from a binary distribution, just copy the "potrace" and "mkbitmap" binaries to a place where the operating system expects them, such as /usr/local/bin. Also copy the files "potrace.1" and "mkbitmap.1" to a directory where the operating system looks for man pages, such as /usr/local/man/man1. For instructions on installing Potrace under Windows, see the file README-WIN USAGE For more detailed usage information, see the man page.

POTRACE LIBRARY (FOR DEVELOPERS) As of Potrace release 1.6, the Potrace core functionality has been separated into a library libpotrace.a. This makes it easy to integrate tracing functionality into other GPL programs. The API of the library is defined in the header file potracelib.h, and is documented in doc/potracelib.pdf. It is not by default installed, but can be installed with the --with-libpotrace configuration option.

Given a point (x,y) (with real-valued coordinates) in the plane, let (xi,yi) be the integer part of the coordinates, i.e., xi=floor(x), yi=floor(y). Define a path from (x,y) to infinity as follows: path(x,y) = (x,y)--(xi+1,y)--(xi+1,yi)--(+infty,yi). Now as the point (x,y) moves smoothly across the plane, the path path(x,y) sweeps (non-smoothly) across a certain area. We proportionately blacken the area as the path moves "downward", and we whiten the area as the path moves "upward". This way, after the point has traversed a closed curve, the interior of the curve has been darkened (counterclockwise movement) or lightened (clockwise movement). (The "grey shift" is actually proportional to the winding number). By choosing the above path with mostly integer coordinates, we achieve that only pixels close to (x,y) receive grey values and are subject to round-off errors. The grey value of pixels far away from (x,y) is always in "integer" (where 0=black, 1=white). As a special trick, we keep an accumulator rm->a1, which holds a double value to be added to the grey value to be added to the current pixel (xi,yi). Only when changing "current" pixels, we convert this double value to an integer. This way we avoid round-off errors at the meeting points of line segments. Another speedup measure is that we sometimes use the rm->incrow_buf array to postpone incrementing or decrementing an entire row. If incrow_buf[y]=x+1!=0, then all the pixels (x,y),(x+1,y),(x+2,y),... are scheduled to be incremented/decremented (which one is the case will be clear from context). This keeps the greymap operations reasonably local. */ /* allocate a new rendering state */ render_t *render_new(greymap_t *gm) { render_t *rm; rm = (render_t *) malloc(sizeof(render_t)); if (!rm) { return NULL; } memset(rm, 0, sizeof(render_t)); rm->gm = gm; rm->incrow_buf = (int *) calloc(gm->h, sizeof(int)); if (!rm->incrow_buf) { free(rm); return NULL; } return rm; } /* free a given rendering state.

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns -1. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call. If LONG_ONLY is nonzero, '-' as well as '--' can introduce long-named options. */ int _getopt_internal (argc, argv, optstring, longopts, longind, long_only) int argc; char *const *argv; const char *optstring; const struct option *longopts; int *longind; int long_only; { int print_errors = opterr; if (optstring[0] == ':') print_errors = 0; if (argc < 1) return -1; optarg = NULL; if (optind == 0 || !__getopt_initialized) { if (optind == 0) optind = 1; /* Don't scan ARGV[0], the program name. */ optstring = _getopt_initialize (argc, argv, optstring); __getopt_initialized = 1; } /* Test whether ARGV[optind] points to a non-option argument.

There are also special states init and stop. emit[b, code] is a function which emits the code 'code' as a b-bit value into the output bitstream. hibit(n) returns the least number of binary digits required to represent n. init ---> {[], newdict, 258} where [] is the empty string, and newdict maps each of the 256 singleton strings to itself.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. 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 Program or any portion of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, 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 Program, 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 Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) 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; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, 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 executable. However, as a special exception, the source code 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. If distribution of executable or 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 counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program 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. 5. 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 Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program 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 to this License. 7. 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 Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program 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 Program. 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. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program 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. 9. The Free Software Foundation may publish revised and/or new versions of the 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 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 Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, 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 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 12. 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 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. 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 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.

Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision 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, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

A number of bugs triggered by malformed BMP files have been fixed, including CVE-2016-8685 and CVE-2016-8686. Error reporting has been improved. The image size is now truncated when the bitmap data ends prematurely. It is now possible to use negative dy in bitmap data. Portability has been improved to encompass C++11. The default compiler is now clang if available. Thanks to Nelson Beebe and Martin Gieseking for reporting portability issues, and to Agostino Sarubbo for reporting bugs. October 22, 2015: Release 1.13 Some critical bugs in the processing of BMP files were fixed. These bugs allowed the program to be crashed, or potentially to be abused in other ways, by feeding it specially crafted BMP files. Thanks to Tomasz Buchert and Agostino Sarubbo for reporting these bugs. Portability was improved for C99 and for MSVC++. Thanks to Peter Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting portability issues. March 24, 2015: Release 1.12 Fixed memory overflow bug triggered by very large bitmaps. Fixed binary file mode on 64-bit Windows. Portability improvements. February 19, 2013: Release 1.11 A GeoJSON backend was added; thanks to Christoph Hormann for contributing this. Support for bitfields in the BMP format was added. A minor change was made to the behavior of the alphamax parameter; a value of 0 now gives a true polygon. August 19, 2011: Release 1.10 A DXF backend was added. The output is in the drawing interchange format used by computer aided design software. Thanks to Jonas Benedett Dorr for testing. The Gimppath backend was changed to be compatible with current versions of Gimp. The EPS, PDF, and SVG backends now use high-resolution bounding boxes. The default scaling of the EPS, PDF, and SVG backends is now fixed at 72dpi. A new option --flat was added to the SVG backend. A new option --tight was added to remove whitespace around the input image before calculating its scaling and placement. December 21, 2010: Release 1.9 The xfig and eps backends were improved, and a fixed pagesize PDF backend was added. Support for BMP version 4 and version 5 files, as well as top-down BMP files, was added. Minor speed improvements to Potrace and major speed improvements to mkbitmap. A Gaussian blur option was added to mkbitmap. Libtool is now used to build and optionally install the Potrace library. An optional simplified progress bar was added for dumb terminals. This release also contains some portability improvements, cross-compilation improvements, and minor bug fixes. April 9, 2007: Release 1.8 This release contains minor bugfixes and portability improvements. Rotation is now implemented in the PDF backend. March 6, 2005: Release 1.7 This is a bugfix release. A bug in the progress bar code, which caused arithmetic exceptions on some 64-bit architectures, has been fixed. February 27, 2005: Release 1.6 This release contains an algorithm improvement that leads to a speedup of 20-60% over previous versions of Potrace. A new PDF backend was added, courtesy of Tor Andersson. An option --progress was added for displaying a progress bar. The Windows version of Potrace now uses MinGW instead of Cygwin, eliminating the need to install a special DLL alongside the executable programs, and solving some problems with wildcards and executable PostScript files. Some spurious "premature end of file" messages were eliminated. The core functionality of Potrace was separated into a library with a documented API, making it easier for developers to incorporate Potrace into other GPL-licensed software. July 8, 2004: Release 1.5 The LZW patent has finally expired in Canada. Therefore, postscript level 2 compression can now be implemented directly within Potrace, without having to rely on the external "compress" program. This release makes the necessary corrections. March 6, 2004: Release 1.4 This is a bugfix release. Fixed the bug which sometimes caused Potrace to "hang" on large input files. Also fixed some bugs in the compression code. The presence of the "compress" program is now determined at run-time, rather than compile-time. No new features or command line options were added. January 15, 2004: Release 1.3 This is primarily a bugfix release. Version 1.2 fatally crashed when applied to an empty (all white) bitmap. The options -2 and -3 are now ignored when unsupported, rather than causing an error. There were some improvements to the test suite, autoconfiguration, and portability. The bounding box in the xfig backend was fixed, and the postscript output now has better page encapsulation. Bitmaps of dimension 0 are now tolerated better. December 23, 2003: Release 1.2 New experimental Gimppath and XFig backends were added. A separate program mkbitmap was added, which can be used as a preprocessor to Potrace. It turns greyscale or color images into high-quality bitmaps with optional scaling and filtering. New options --opaque, --group, and --fillcolor were added for greater flexibility in generating editable PostScript and SVG output. The bitmap decomposition algorithm was improved and can now take advantage of 64-bit platforms. Portability and autoconfiguration were vastly improved, and a test suite was added. Runlength encoded BMP files can now be read. Some bugs in command line options were fixed. August 18, 2003: Release 1.1 The most important new feature of this release is an SVG (scalable vector graphics) backend. This file format can be read by vector graphics manipulation programs such as sodipodi, as well as web browsers with an SVG plugin. I also added PGM, PPM, and BMP as additional input file formats. The new --blacklevel and --invert options control how non-black-and-white images are converted to bitmaps before being processed by Potrace. The implementation of a critical function has been improved to make Potrace even faster on large input files; this results in speedups of up to factor 3.3 relative to Potrace 1.0. Autoconfiguration was improved, and the code was polished to compile on more different architectures. The error messages for wrong file formats were also improved. August 10, 2003: Release 1.0 First public release. potrace-1.14/AUTHORS0000664000175000017500000000050412576527766011115 00000000000000Known contributors are listed here, in alphabetical order by their abbreviations (which are used in Changelog).

(2017/02/18) PS1 - corrected some exit codes, added some missing error handlers. (2017/02/17) PS1 - mkbitmap: bugfixes and improvements in parsing image files. (2017/02/15) PS1 - truncate the image size when bitmap data ends prematurely. This fixes CVE-2016-8686, where Potrace appeared to be "hanging" on a crafted input file. (2017/02/14) PS1 - test suite: added tests for plain pnm files. (2017/01/08) PS1 - fixed potential compiler issues due to signed arithmetic overflow and arithmetic shifting. (2017/01/07) PS1 - enable use of negative dy in bitmap data. (2017/01/07) PS1 - test suite: moved data files to a subdirectory. (2017/01/07) PS1 - test suite: added a check for -i flag. (2017/01/07) PS1 - fixed buffer overflow CVE-2016-8685, reported by Agostino Sarubbo. (2015/10/24) PS1 - portability: use const char * for string constants, required by C++11. Reported by Martin Gieseking. (2015/10/24) PS1 - portability: extra spaces around string macros, required by C++11. Reported by Martin Gieseking. (2015/10/24) PS1 - portability: added more potential C compilers to autoconf. Suggested by Nelson Beebe. v1.13 2015/10/22 (2015/07/18) PS1 - fixed heap overflows, null pointer dereference bugs and a memory leak. Reported by Agostino Sarubbo. (2015/05/17) PS1 - man page: show which backends are dimension based, and state more clearly that svg backend defaults to 72dpi. (2015/04/11) PS1 - portability: ssize_t not supported on some systems; use ptrdiff_t instead. Reported by Martin Gieseking. (2015/03/28) PS1 - portability: added missing #includes for c99, reported by Nelson Beebe. (2015/03/27) PS1 - include config.h before other header files, reported by Peter Breitenlohner. (2015/03/26) PS1 - fixed division by zero bug triggered by bitmap of dimension 1x0. Reported by Tomasz Buchert. v1.12 2015/03/24 (2015/03/20) PS1 - fixed memory overflow bug triggered by very large bitmaps. Fixes RedHat bug #955808 reported by Vincent Danen and Debian bug #778646 reported by Moritz Muehlenhoff. (2014/09/06) PS1 - test suite: added binary-check, to check that files are written in binary mode. Mostly relevant on Windows. (2014/09/06) PS1 - portability: fixed potential binary file mode bug on MinGW64. (2014/03/30) PS1 - man pages: fixed leading blank page with groff -man -Tps. (2013/12/29) PS1 - portability: made regular expressions in test suite POSIX compliant, reported by Ben Bullock. (2013/05/14) PS1 - distribution: removed libtool from distribution. v1.11 2013/02/19 (2013/02/10) PS1 - bitops.c: added "cc" as a clobbered register. (2012/09/13) PS1 - GeoJSON backend: -u option affects rounding, not scaling. (2012/09/12) CH1 - added GeoJSON backend. (2012/03/04) PS1 - minor change in behavior of alphamax parameter: make a corner if alpha >= alphamax (instead of >). This makes little practical difference, except when alphamax = 0, in which case we now get a polygon. Fixes bug #3495854, reported by scribbleink. (2012/02/24) PS1 - added support for BMP format with bitfields. v1.10 2011/08/19 (2011/08/07) PS1 - added --tight option (2011/08/05) PS1 - backends: simplified dimension calculations (2011/08/05) PS1 - eps backend: prevent integer overflow in bounding box.

Please see the general README file and the man page for general information on usage, how to compile Potrace, etc. INSTALLATION for Windows 95/98/2000/NT/XP/Vista/7/whatever: =========================================================== Download the file potrace-XXX.win32.zip (or potrace-XXX.win64.zip if you want the 64-bit version). Unpack it with your favorite unzipping tool, such as unzip, 7-Zip, WinZip, or just right-clicking on the file. If you have "tar" and "gunzip" installed, you may also get the tar.gz file instead of the zip file. The distribution includes the executable programs potrace.exe and mkbitmap.exe. You need to move these files to a place where Windows looks for programs, for example C:\WINDOWS. Alternatively, you can amend your PATH environment variable, by adding something like the following line to C:\AUTOEXEC.BAT: PATH=%PATH%;C:\DIRECTORY\WHERE\FILES\ARE Note: as of version 1.6, the Potrace Windows distribution is built using MinGW and not Cygwin. It is no longer necessary to install a separate DLL file with Potrace. RUNNING: ======== For non-Windows specific usage information, see the file README. Potrace on Windows runs in much the same way as under Linux and other Unix-like operating systems. You must run Potrace from the command line (also known as the MSDOS Prompt). File names can be given in Unix style or Windows style, thus the following will both work: potrace h:/data/file.txt potrace h:\data\file.txt Wildcards can also be used, as in: potrace h:\data\*.* potrace h:/data/*.* Earlier versions of Potrace had some problems when wildcards and backslashes were mixed; these problems seem to have been solved by the switch from Cygwin to MinGW. Another problem that some users have reported is that the generated ".ps" and ".eps" were not executable under Windows (i.e., one could not simply display these files by typing their name on the MSDOS Prompt, as should normally be the case if a default application for PostScript files has been configured). I was never able to replicate this problem, but I believe that it has also been solved by the switch to MinGW. potrace-1.14/test-driver0000754000175000017500000001104013052454503012207 00000000000000#! /bin/sh # test-driver - basic testsuite driver script. scriptversion=2013-07-13.22; # UTC # Copyright (C) 2011-2014 Free Software Foundation, Inc. # # 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 2, 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.

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.

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.
