The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. Xpdf runs under the X Window System on Unix, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty much any system with a decent C++ compiler. Major changes: * Added the "fixed pitch" text extraction mode. * Modified "pdftops -paper match" to handle PDF files with different-sized pages, i.e., it will now select the matching paper size on a page-by-page basis. * Add ability for pdftoppm to write to stdout. * Added the pdfdetach tool. * Implemented 256-bit AES decryption. * Commented out the t1lib section in the configure script -- t1lib has some potential security holes, and hasn't been updated in years. * Redesigned the font configuration xpdfrc commands: removed the displayFontT1, displayFontTT, displayNamedCIDFontT1, displayCIDFontT1, displayNamedCIDFontTT, displayCIDFontTT, psFont, psNamedFont16, and psFont16 commands; added the fontFile, fontFileCC, psResidentFont, psResidentFont16, and psResidentFontCC commands. * Switched from GPLv2 to dual v2/v3 licensing. See the `CHANGES' file for a complete list of changes. Source (C++ and C) is available, and it should be fairly easy to compile for UNIX, VMS, OS/2, and Win32. More information, source code, and precompiled binaries are on the xpdf web page and ftp site: http://www.foolabs.com/xpdf/ ftp://ftp.foolabs.com/pub/xpdf/ For information on commercial licensing and consulting, please see the Glyph & Cog web site: http://www.glyphandcog.com/ xpdf-3.03/vms_make.com0000644000076400007640000004675011622305345014231 0ustar dereknderekn$!======================================================================== $! $!

Email: derekn@foolabs.com WWW: http://www.foolabs.com/xpdf/ Compiling xpdf -------------- Xpdf is written in C++ (with a little bit of C). It should work with any ANSI-compliant C++ and C compilers. The systems and compilers it's been tested with are listed on the xpdf web page. Xpdf requires the Motif (or Lesstif) toolkit. The following notes give specific instructions for compiling on different systems. ************** *** UNIX *** ************** * Install FreeType 2 (this is required). WARNING: You must have version 2.0.5 or newer. Some older versions of XFree86 ship with an older version of FreeType, which means you'll need to explicitly set include and library paths to get the correct version: --with-freetype2-library=PATH --with-freetype2-includes=PATH (The include path is the directory which contains the freetype2 directory, i.e., do NOT include "freetype2" in the --with-freetype2-includes path. For example, with the default installation, the library path is /usr/local/lib and the include path is /usr/local/include/freetype2.) * If you have Motif (or Lesstif) installed in a non-standard place, you can use the following options to tell configure where to find it: --with-Xm-library=PATH --with-Xm-includes=PATH * Run the configure script: ./configure This should produce a set of makefiles customized for your system. The configure script accepts the following options (in addition to the usual things accepted by autoconf configure scripts): --prefix=PREFIX Changes the directory where xpdf is installed. The default is /usr/local. --enable-a4-paper Switches the default paper size for PostScript output (xpdf and pdftops) to A4. The default is Letter size. --enable-no-text-select With this option, xpdf will not copy text. (This is only useful on closed systems where the user can't get at the PDF file directly.) --enable-opi Enables support for generation of OPI (Open Prepress Interface) comments with pdftops. --sysconfdir=DIR Look for the system-wide xpdfrc config file in this directory. The default is PREFIX/etc. --with-appdef-dir=DIR Use the specified app-defaults directory. The default is /usr/lib/X11/app-defaults. If you need to pass specific options to the C and/or C++ compiler, you can set the CFLAGS and/or CXXFLAGS environment variables before running the configure script. Any options given that way will be added to the CFLAGS/CXXFLAGS used by all of the Xpdf makefiles. * Type 'make'. This should build the executables: xpdf/xpdf xpdf/pdftops xpdf/pdftotext xpdf/pdfinfo xpdf/pdffonts xpdf/pdfdetach xpdf/pdftoppm xpdf/pdfimages * If desired, type 'make install' to install the binaries and man pages. The old Makefile.config and Makefiles are no longer provided or supported. If you really want to manually configure Xpdf (which is not recommended), the files that need to be created are aconf.h, Makefile, goo/Makefile, fofi/Makefile, splash/Makefile, and xpdf/Makefile, all of which are generated from the corresponding '.in' files. If you want to run a quick test, there is a tiny PDF file included with xpdf, as misc/hello.pdf . ************* *** VMS *** ************* * The 'stddef.h' include file which comes with older versions of gcc may be missing a definition for wchar_t.

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 Appendix: 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. Copyright (C) 19yy 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 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. 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) 19yy 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. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. xpdf-3.03/splash/0000755000076400007640000000000011622305345013205 5ustar derekndereknxpdf-3.03/splash/SplashState.h0000644000076400007640000000576311622305345015624 0ustar dereknderekn//======================================================================== // // SplashState.h // //======================================================================== #ifndef SPLASHSTATE_H #define SPLASHSTATE_H #include #ifdef USE_GCC_PRAGMAS #pragma interface #endif #include "SplashTypes.h" class SplashPattern; class SplashScreen; class SplashClip; class SplashBitmap; //------------------------------------------------------------------------ // line cap values //------------------------------------------------------------------------ #define splashLineCapButt 0 #define splashLineCapRound 1 #define splashLineCapProjecting 2 //------------------------------------------------------------------------ // line join values //------------------------------------------------------------------------ #define splashLineJoinMiter 0 #define splashLineJoinRound 1 #define splashLineJoinBevel 2 //------------------------------------------------------------------------ // SplashState //------------------------------------------------------------------------ class SplashState { public: // Create a new state object, initialized with default settings.

Implemented inline images. Fixed (mostly) disjoint polygon fills. Added remote server stuff. Added page number on command line. Fixed problem with font encodings which caused character misalignment. Fixed inverted CCITT decoding and inverted image mask drawing. Now compiles under gcc 2.7.x (ignore those stupid 'unused parameter' warnings). Many minor bug fixes and optimizations. 0.4 (96-apr-24) --------------- Implemented DCT filter. Implemented PostScript output; wrote pdftops program. Implemented links. Implemented font rotation -- I was wrong: X11R6 servers *do* support font rotation (by specifying a matrix in place of a size). Added bindings for Home/End, Page Up/Down, arrow keys. Added initialZoom resource and -z option. Added geometry resource and -g option. Fixed image size off-by-one bug. Fixed bug where page content is reference to an array of streams. Cleaned up uninitialized variables which were causing random problems on various platforms. Manually skip whitespace before calling atoi() for startxref. Replaced calls to XrmCombineFileDatabase() with calls to XrmGetFileDatabase() and XrmMergeDatabases() so it will work under older versions of X. Fixed problem with reading multiple xref tables in updated PDF files. Check for encryption and print appropriate error message. Rudimentary dithering of images. Fixed bug in CCITTFax filter (pass mode followed by horizontal mode). Optimized drawImage() and drawImageMask(). Changed several things to ease porting: - changed '__inline' to 'inline' (to adhere to the ANSI standard) - surrounded interface/implementation pragmas with #ifdef _GNUC__ - got rid of empty array initializer lists - moved Operator type definition from Gfx.cc to Gfx.h - renamed String, uint, etc. - ability to uncompress to file (NO_POPEN and USE_GZIP flags) - added definitions of XK_Page_Up/Down and XPointer for old versions of X For VMS port: - use correct Xdefaults name for VMS, get rid of ltkGetHomeDir() - added '#include ' before all X includes - renamed files with multiple periods in their names Fixed window resizing infinite oscillation bug. Fixed problem with string-type (as opposed to stream-type) indexed color space lookup tables (which are used in inline images). If an X font is not found, try smaller and then larger sizes (this is useful for old or broken X servers which can't scale bitmap fonts). Added -rgb (color cube size) option. Various minor bug fixes. 0.5 (96-may-23) --------------- Fixed bug in LTKWindow which broke the remote server mode. Fixed PostScript output: - doesn't seg fault if file is unwritable. - incorrect DSC comment - need colon in '%%Page:'. - use 'imagemask' command for masks. - output filters in the correct order. - Stream::isBinary() checks the next-to-bottom, not top, stream. - if page width > height, rotate it 90 degrees. - if page is larger than paper size, scale it down. Set default MediaBox to 8.5" x 11" to deal with non-compliant PDF files which don't specify a MediaBox. Added DEBUG_MEM stuff in gmem.c and gmempp.cc. Fixed memory leaks: - LTKWindow didn't delete the LTKBox. - LinkAction needs a virtual destructor. Use $(RANLIB) variable in goo/Makefile and ltk/Makefile. Allocate image data after calling XCreateImage, using image->bytes_per_line -- works in 24-bit mode now. DCTStream rounds width of rowBuf lines up to the next multiple of mcuWidth, so last MCU doesn't run off end of buffer. Increase size of block (from 255 to 1024 bytes) read at end of file to search for 'startxref'. Skip past garbage at start of file, look for '%PDF'. Moved more compiler options out of Makefiles into Makefile.config. Top-level Makefile uses '$(MAKE)' instead of 'make' for making subdirectories. Space/PageDown/Next and Backspace/PageUp/Previous now moves to next/previous page if already scrolled to bottom/top of current page. 0.5a (96-jul-09) ---------------- [not a public release] For PDF 1.2 (a.k.a. Amber, a.k.a. Acrobat 3) support: - look for trailer after first xref instead of at end of file. Deal with font subsets by converting character names of the form 'Cnnnn' to the appropriate character from the standard encoding. Extract encoding from embedded Type 1 fonts. Kludge to fill one-pixel thick polygons. Changed X font encoding to use endash for hyphen (gets rid of too-long hyphens). Handle Resources key in Pages dictionaries (needed for pstoedit output). Fix comment handling in Parser (needed for pstoedit output). Move Bezier curve conversion from GfxState to XOutputDev; look at flatness parameter in GfxState. Change all of the path functions in XOutputDev (stroke, fill, clip) to use the same path transformation/conversion function. Rewrote PostScript output driver as a subclass of OutputDev; removed duplicated code (ps_ functions) from Gfx. Fixed bug in xref code with small (< 1024 bytes) PDF files. Implemented BX/EX operators. Added PDFDoc class. 0.6 (96-nov-12) --------------- Add support for PostScript output to stdout (-) and to a command (|lpr); added -ps option and psFile resource. Decryption is implemented but not included in the distribution due to legal restrictions: the decryption algorithm is a trade secret of RSA, Inc., and the U.S.A. still has bogus export controls on cryptography software. Added .xpdfrc config file: - Added fontmap parameter: user can map PDF font names to X fonts. - Added fontpath parameter: search for Type 1 font if encoding is not in PDF file. Incremental display: display is updated after every 200 commands. Added forward and backward by-10-page buttons. Links: - Implement links with "Launch" actions that point to PDF files. - Draw borders around links. - Handle links with named destinations. - GoToR links specify a page number instead of a page reference. Optimizations: - Rewrote Stream to use buffering, and added lookChar() functions; rewrote Lexer to take advantage of this. - Use hash tables for name->code mapping in font encodings. - Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and changed the flatness test. Added file name to window title. Implemented RunLength filter. Implemented forms. Convert ObjType to an enum. Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with incorrect PDF files. Changed color selection so that very pale colors don't map to white. Fixed bug in CCITTFax filter (multiple make-up codes). In GString::clear(): need to set length to 0 before calling resize(). Base initial window size on first displayed page, not page 1; deal correctly with rotated pages. Added ltkGetIntResource() and LTKApp::getIntResource(). PostScript output fixes: - Escape backslashes in strings. - When doing ASCII85 encoding, keep both chars of EOF marker ('~>') on same line. - Add extra line '%-EOD-' after image data streams; call wrapper functions for image and imagemask which look for this line -- this should fix the 'too much data in stream' bug. - Font tags can be reused for different fonts on different pages -- so use font object reference (number/generation) instead. Initialize character widths to zero (this caused crashes on OSF/1). Handle image masks which go outside of pixmap. Makefile.config changes: - Remove -o in C++ compile rule. - Add $(AR) variable. Code which read char widths from font dictionary read all but the last width. Add 'return 0;' to main() in xpdf and pdftops. Allow fonts to use StandardEncoding. Convert man pages to VMS help files. 0.7 (97-may-28) --------------- Implemented FlateDecode filter (for PDF 1.2). Basic xref table reconstruction for damaged files New pdftotext program converts PDF to plain text. Implemented menus in LTK; added a menu to xpdf. Added open and save functions; allow xpdf to start without any PDF file. Implemented text find. Implemented text select/copy. Change mouse cursor when it's over a link. Embed Type 1 fonts in PostScript output. Moved rotate functions to menu; added quit to menu. Fixed stroke color bug in PostScript output (was using fill color instead of stroke color; this sometimes caused lines to be missing (white) in PostScript output). Support Launch-type links -- pops up a dialog before executing anything. Expects the A (action) dictionary to contain a Unix dictionary with F (file) and P (paremeter) keys just like the Win dictionary. A moveto op all by itself should just be discarded, instead of generating a subpath with one point (this was causing seg faults). Balanced parentheses in strings don't need to be escaped. Tj operator in PostScript prolog didn't check for zero when dividing by length of string. Implemented selection in LTK; TextIn widgets support dragging/copy/ paste. Handle font subsets that use hex character codes. Added icon pixmap; added the XPMLIB and NO_XPM variables to Makefile.config. Fixed subtle bug in use of horizontal scaling parameter (it affects only the width of drawn characters, not positioning done in text space). Memory testing (with DEBUG_MEM): - gmalloc now fills memory blocks with garbage to catch unitialized fields. - gfree fills memory blocks with garbage to catch uses of freed blocks. Handle image masks which go off the pixmap on the top and/or left. Fixed inline functions which had two return statements (to make the HP, SCO, and other cfront-based compilers happy). Fixed bug which caused seg faults when following a link to a different file (info in LinkGoto object was used after link was deleted by loadFile). If page content is an array of streams, the streams are concatenated; objects and commands can span multiple streams. If file open fails, try lower-casing and upper-casing the file name. Commands should end when lexer sees a '/' character. GString::append(char *, int) was broken. Changed LTKScrollingCanvas redraw to be more efficient: copy as much as possible from window before copying from off-screen pixmap. Ignore gs (set extended graphics state) operator. Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the weird colorspaces are not yet implemented). Named destinations (for links) can be strings as well as names; deal with the names tree in the catalog. Clip to the page CropBox. Added '-q' to gzip options (to suppress warnings, in case user has -v in GZIP env var). Added 'include Makefile.config' to top-level Makefile. Added INSTALL variable to Makefile.config; used in top-level Makefile. Always initialize LinkDest left/bottom/top/right/zoom fields (bogus floating point values were causing crashes on Alpha). Added Makefile.config options for Digital Unix (DEC compilers), HP-UX (HP compilers), SCO Unix, and Evans & Sutherland ES/OS. Added flag to set stream mode in fopen call for VMS. Rewrote Link module. Pages with no contents shouldn't cause an error message. In PostScript output: pdfImM needs to set fill color before doing imagemask. If font doesn't specify character widths, use widths from built-in font, based on font flags. Fixed LTK scrollbar to delay before repeating and to control the period between repeats. Removed window/widget copy() methods (they were untested and unused). Unknown filter types produce a single error message instead of a stream of errors. Added a dummy target in top-level Makefile so making individual executables (e.g., 'make pdftops') should now work. Added optional xpdf-flip.ltk with buttons on right side instead of bottom of window. 0.7a (98-feb-22) ---------------- Moved find command from menu to toolbar button ('f' key still works). Support TrueColor visuals. Added a -cmap option and a installCmap resource to install a private colormap. Mouse button 2 pans the window. Selecting a URI link now executes a configurable command (from the urlCommand resource). Added a "link info" display which shows the URL or file for the link under the mouse. Don't draw (or convert to PostScript) text drawn in render modes 3 and 7 -- this is invisible text, used by Acrobat Capture; this text is still passed to the TextPage object so that selection works. Recognize (and quietly ignore) marked content operators (BMC, BDC, EMC, MP, DP). Recognize new color-setting operators (scn, SCN). Added A4_PAPER option. Embed external Type 1 font files (this currently only works with PFA files). Added "-level1" option (in xpdf and pdftops) to generate Level 1 PostScript. Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT flag, and use configure to autodetect (for HP-UX). Fixed appendToPath() to behave reasonably when appending ".." to root directory. Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf to crash under OSF/1). ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and could run past the end of the stream in damaged files. Handle hex escapes (#xx) in names. Still allow the name /# for backward-compatibility. Check for NULL characters in encoding array in GfxFont.cc (was calling strcmp() with NULL which crashed under Solaris). PageAttrs::PageAttrs() didn't initialize crop box boundaries. Changed uses of lookup() to lookupNF() in XRef.cc. Fixed type checking of operators which take a variable number of args. Gfx::buildImageStream() doesn't need to check for parser (since I got rid of the bogus array-of-command thing). XOutputFont matches on font reference instead of font tag (similar to PSOutputDev fix). Fixed bug in position calculation for multi-char substitutions in XOutputDev. Cleaned up local variables which hid class variables. Optimized variable length decoding in CCITTFaxStream. Set link border width to zero if Border dictionary entry is missing. Throw away zero-length strings in TextOutputDev -- they don't have valid xMin/xMax values. Swapped order of XLIBS and XPMLIB in xpdf/Makefile. Deleted 'LTKApp::' in function declaration in LTKApp.h. Changed '(XKeyEvent *)&event' to '&event.xkey' in LTKApp.cc. Check that the link rectangle coordinates are in the correct order, and swap if necessary. TextOutputDev didn't set text to NULL, which caused pdftotext to segfault if it couldn't open it's output file. Fixed a hash table search bug in GfxFontEncoding::getCharCode(). Cleaned up colorspace code: rewrote GfxColorSpace and added GfxImageColorMap; cleaned up PSOutputDev::doImage. Handle named colorspaces in images. Correctly set the default color after a colorspace change. Old setcolor operators now set the colorspace. Fixed bug with uncompressed blocks in FlateStream. Fixed bug with fixed Huffman code table in FlateStream. Added hash table of X windows (for LTKWindow and LTKWidget) to LTKApp and replaced calls to XQueryTree with hash table searches -- this avoids a roundtrip to the server for each event and also fixes the problem where XQueryTree crashed if the window no longer existed (with leftover events from a destroyed window). (Thanks to Yair Lenga for the suggestion.) Create a new GC for selection -- xor black and white (instead of LTK foreground and background). Fixed crash with blank lines in .xpdfrc. Allow spaces in font descriptors in fontmap lines in .xpdfrc. Check for bogus object number in XRef::fetch(). Use MacRomanEncoding for TrueType fonts that don't specify an encoding. Certain PDF generators apparently don't include FontDescriptors for Arial, TimesNewRoman, and CourierNew -- set GfxFont flags appropriately. Fixed a bug in width guessing in GfxFont -- sans serif and serif were swapped. Rewrote XRef::readXRef() to avoid using a parser to read the xref entries. Added NO_TEXT_SELECT option. Ignore APPn/COM/etc. markers in DCT streams. Replaced select() with XMultiplexInput() in LTKApp.cc for VMS. Handle WM_DELETE_WINDOW protocol -- if you ask the window manager to delete the xpdf window, xpdf will exit cleanly; other windows/dialogs are simply closed. Optimized DCT decoder; switched to integer arithmetic. The "/Type /Annots" field in an annotation dictionary is optional. Check for null nameTree in Catalog::findDest(). In XOutputDev, search user font map before default font map. Added "normal" SETWIDTH parameter to all font descriptors in XOutputDev (some systems have a narrow-width Helvetica font). Added FOPEN_READ_BIN and FOPEN_WRITE_BIN to support Win32. Added a hack which allows better font substitution for some Type 3 fonts. Also allow character names of the form /nn and /nnn. Added and to LTKApp.cc (needed by AIX and IRIX for bzero() declaration for FD_ZERO). 0.80 (98-nov-27) ---------------- Support for some Japanese fonts (Type 0 fonts using the Adobe-Japan1-2 character collection, horizontal only). Added pdfinfo application. Added pdftopbm application. Added pdfimages application. Added -papercolor option and .paperColor resource. Fixed divide-by-zero problem in XOutputDev Type 3 font matrix kludge. Font subset char names can be 'Bxx' as well as 'Cxx' and 'Gxx'. Fixed bug in color space conversion in DCTStream filter (YCC->RGB was correct, YCCK->CMYK was broken). Added XRef::getDocInfo() and PDFDoc::getDocInfo() to support pdfinfo. Optimized GfxImageColorMap. Lexer::getStream(), getPos(), and setPos() check for null stream. Decryption code now does strings as well as streams. ASCII85 decoder rounds short tuples up instead of down. CropBox and MediaBox can be non-integers. PostScript output: - Use a rectangle operator. - Call setpagedevice with page size. - Insert %%PageOrientation comments. - Add paper size flags (-paperw and -paperh) to xpdf and pdftops. - If HAVE_POPEN is not defined, and user tries to print to '|...', the PSOutputDev destructor tried to write to the PS file. - Added support for forms (pdftops -form). Removed error messages for empty paths in stroke, fill, etc. operators. Don't allow flatnesses less than 1 in XOutputDev (this speeds up rendering a little bit when there are lots of tiny curves). Moved the font subset character name guessing from GfxFont to XOutputDev and TextOutputDev - now these files print correctly. Cast argument to XFree() to XPointer; add XPointer definition where necessary (portability fixes). Various minor VMS fixes. Changes to configure script and Makefiles: - Print a warning if X is missing. - Use C++ when checking select() argument type (HP-UX). - Use 0 instead of NULL when checking select(). - Default to gcc instead of c++. - Get rid of AC_C_INLINE -- this is meant for C, not C++. - Changed -USE_GZIP to -DUSE_GZIP. - Added ability to compile ouside of the source tree. - Added .cc.o rule to {goo,ltk,xpdf}/Makefile.in. - Added @LIBS@ to XLIBS in xpdf/Makefile.in. - In top-level Makefile.in: added '-' to clean commands; added distclean rule. - Create install directories. - Use INSTALL_DATA (instead of INSTALL) for man pages. - Changed xpdf-ltk.h rule to avoid leaving an empty file when ltkbuild fails. - Change things so that by default, ltkbuild is not built and xpdf-ltk.h is not rebuilt. - Use AM_PROG_CC_STDC to add compiler flags for ANSI C. - Modify autoconf's builtin macros to check for xlC. - Use Steve Robbins' smr_CHECK_LIB to test for pixmap library (Xpm) -- this should fix the problems on systems that have the library but not the include file. - Added better test for sys/select.h, sys/bsdtypes.h, strings.h, bstring.h. - New VMS make scripts from Martin P.J. Zinser. - Moved dependences into Makefile.in -- this gets rid of problems with 'cc -MM' (which is gcc-specific) and 'include Makefile.dep' (which isn't supported by all make implementations). Also changed all non-system include files to '#include "..."' (from '<...>'). Tweaked the TextOutputDev heuristics slightly. Modify Gfx to use a stack of resources -- this is necessary for Form XObjects, which can define their own local resources; also modified PSOutputDev to dump fonts used by forms. Look for excessively large MediaBox (compared to CropBox) and shrink it to CropBox. Minor fix to scrolling when dragging a selection. Various patches for pdftex and Win32 support. Deal with Separation colorspaces by using their alternate colorspace entry. Added PBMOutputDev for pdftopbm application. Added ImageOutputDev for pdfimages application. Separated XOutputDev into LTKOutputDev + XOutputDev. Added support for 1-D and mixed 1-D/2-D (Group 3) decoding to CCITTDecode filter. Added resetImage(), getImagePixel(), and skipImageLine() to Stream class; used these in XOutputDev, PSOutputDev, and ImageOutputDev. Implemented predictor for LZW and Flate filters. In pdfImM1 in PSOutputDev prolog: div should be idiv. Changed output from printUsage() function in parseargs to look nicer. 0.90 (99-aug-02) ---------------- Added Type 1/1C font rendering, using t1lib. Added "backward" and "forward" buttons. Added fit-page and fit-page-width zoom factors; replaced zoom-in and zoom-out buttons with a zoom popup menu. Type 1C fonts are converted to Type 1 and embedded in PostScript. Support vertical Japanese text. Added Japanese text support (EUC-JP) to pdftotext. Bumped PDF version to 1.3. Added stub functions for ri and sh operators. (But there are still some missing 1.3 features.) Added -raw option to pdftotext. Minor changes to allow compiling under MS Visual C++ 5.0. Top-level makefile: changed 'mkdir -p' to '-mkdir -p'. Configure script: added X_CFLAGS to smr_CHECK_LIB(Xpm). Added Xpm_CFLAGS to xpdf/Makefile.in (this is needed to get the -I for the xpm includes). Rewrote code that handles font encodings; added support for Type 1C fonts. In the setpagedevice dictionary in PostScript output - added a /Policies entry which tells the PS interpreter to scale the page to fit the available paper. Changed PageUp behavior slightly: move to bottom (instead of top) of previous page. TextPage used character's dx (width + char space) instead of just its width. Read base URI from document Catalog (for URI-type links). Minor change to configure script to avoid using 'unset'. Fixed bugs in CropBox inheritance. Fixed a bug in resource stack handling for form objects. Display forms even if they have a missing/incorrect FormType. Fixed a bug in stream predictors -- the predictor parameters (width, comps, bits) don't need to match the actual image parameters. Completely rearranged the predictor code. Fixed PostScript output to correctly handle stream predictors. Don't segfault on empty (zero-page) documents. Added the xpdf.viKeys feature. Added the ffi and ffl ligatures to XOutputDev and TextOutputDev. Pdftotext and pdfimages now check okToCopy(). Added a '-q' flag to all programs (except pdfinfo) to suppress messages and errors. Deal with DeviceN colorspaces by using their alternate colorspace entry. Change PostScript output so setpagedevice is only called once, at the very beginning of the document (to avoid problems on duplex printers). Changes to configure script and makefiles for DOS/DJGPP. FontEncoding::getCharCode() looked for (code>0) instead of (code>=0). Added keypad arrow keys, etc. to xpdf. Minor changes to gfile.{h,cpp} () to compile under VC++. Fixed CCITTFaxStream to correctly handle all parameters. Modifications to gfile.{h,cc} for Acorn. Some minor changes for OS/2. Added 'SHELL = /bin/sh' to Makefiles. Compare file version to pdfVersionNum+0.0001 to avoid floating point precision problems. Added LDFLAGS to Makefiles. Removed strip entirely from configure and Makefiles. Fixed a bug in choosing the correct DCTStream color transform. 0.91 (2000-aug-14) ------------------ Added TrueType font rendering, using FreeType. Support for Chinese fonts (Type 0 fonts using the Adobe-GB1-2 character collection). Decryption code is included with the main distribution (now that the US export regulations are a little bit less irrational). Added (very basic) support for generating PostScript with Japanese fonts -- only tested with ghostscript so far. Added support for generating EPS files (pdftops -eps). Much-improved image filtering in xpdf (for downsampling and for transforms other than 0/90/180/270-degree rotations). Implemented a basic full-screen (presentation) mode (xpdf -fullscreen). (There is currently no way to switch between window and full-screen modes on the fly -- this will be fixed in a later release.) Added "reload" menu item. Do a better job with anti-aliased Type 1 fonts on non-white backgrounds. Handle Lab color spaces. Handle non-null user passwords. Avoid security hole with tmpnam()/fopen() -- added openTempFile() in goo/gfile.cc. [Thanks to Joseph S. Myers for pointing this out.] Filter out quote marks (' and ") in URLs before running urlCommand to avoid a potential security hole. [Thanks to Frank Doepper for pointing this out.] Fixed TrueColor detection to look at the complete list of available visuals, not just the default visual. In gfile.h, changed NAMLEN(dirent) macro to NAMLEN(d). Removed copyright character from start-up banners. In the open and save dialogs, if the open/save button is pressed with no file name, the dialog is not canceled. Added Xpm_CFLAGS to ltk/Makefile. XOutputDev::updateLineAttrs was using dashLength before it was defined. In top-level Makefile.in, use INSTALL_PROGRAM instead of INSTALL. In man page, recommend -q instead of -err in .mailcap. Changes for GNOME / Bonobo support: - Separated Stream classes into BaseStream and FilterStream trees. - Got rid of all FileStream-specific stuff. - Added a PDFDoc constructor that takes a BaseStream* instead of a file name. Allow newlines inside strings (Photoshop does this). Don't require whitespace between tokens in consecutive content streams (for pages that specify an array of streams). Look at MissingWidth when constructing font character widths array. Fixed a bug that caused incorrect PostScript output for images that use 8-bit indexed color spaces with < 256 colors in the palette. Handle case where embedded font file is bad (this was seg faulting). Minor changes for Windows/pdftex. Work around a bug in PDF files from the IBM patent server. Fixed bugs in PostScript form generation: use pdfStartPage instead of pdfSetup; problem with inline images. Minor bug fix in FlateStream::loadFixedCodes(). Added %%DocumentMedia and %%PageMedia comments to the PostScript so that gsview (a Windows frontend for ghostscript) gets the right paper size. Draw AcroForm fields that have appearance annotations. Bounds check gray, CMYK, and RGB values (in GfxColor). Moved the link border drawing code into Page (from PDFDoc). Minor modifications for pdftohtml. PSOutputDev: use the Type 3 font scaling kludge from XOutputDev. Separation color spaces were handled incorrectly in images. Fixed a bug with form bounding boxes. Modified the t1lib support -- replace libt1x code with my own code. Type 1 and TrueType fonts are now handled similarly, and clipping works on Type 1 fonts. Don't print copyright banner (xpdf); add -v switch to get copyright and version info (all apps); get rid of -err switch (xpdf). Automatically reload the PDF file if it has been changed, i.e., if the modification time is different. Fixed a memory (malloc size) bug in CCITTFaxStream. Fixed two bugs in FontEncoding::hash() -- handle zero-length character names (which were found in a (buggy?) PDF file), and handle character names with high-bit-set characters (use unsigned ints). Added PDFDoc::isLinearized() and corresponding code in pdfinfo.cc. Handle files with an incorrect page count in the Pages dictionary (FOP, from the Apache project produces a page count of 0). Handle TrueType equivalents to the Base14 fonts (Arial, TimesNewRoman, CourierNew) -- Adobe's tools use these names without embedding the fonts. Tweaked the Type 3 font sizing kludge. Changed pdfimages (ImageOutputDev) so it doesn't output JPEG files for 4-component color spaces, since these seem to confuse most image viewers. Added support for generating OPI comments (pdftops -opi). In XOutputDev::drawImage() and drawImageMask(), check for images that are completely off-page. Use the provided alternate or a default (DeviceGray/RGB/CMYK) color space for ICCBased color spaces. Incorporated MacOS-specific code from Leonard Rosenthol. Configure script switches to C++ for the strings.h/bstring.h test. Gfx::opRestore() calls clearPath() to handle (apparently) buggy PDF files produced by FreeHand. The /Type field in most dictionaries is optional (PDF 1.3 change). Move printCommands variable definition into Gfx.cc. If page is smaller than paper, center the PostScript output. Fix a minor bug in the SELECT_TAKES_INT detection in the configure script. TextOutputDev filters out control characters. Changed enough occurrences of 'char *' to 'const char *' to keep gcc 2.95 from barfing. Support for Latin-2 and Latin-5 in pdftotext (however, this will only work if the PDF file contains correct font encodings, which seems to be rare). TextOutputDev converts "eightoldstyle" to "eight", etc. Don't use the return value from sprintf() -- most systems return the length, but some return the string. Minor fixes for SunOS 4. Configure script looks for both select() and fd_set in sys/select.h. Configure script checks for gethostbyname() in -lbsd (for LynxOS). Fix missing closepath bug in PostScript output. Change PostScript portrait/landscape mode selection so it only uses landscape if the page width is greater than the paper width. Tweaked the VMS code in makePathAbsolute(). 0.91a (2000-oct-11) ------------------- Implemented separable CMYK PostScript output (the -level1sep switch to pdftops). Implemented Pattern color spaces with tiling patterns (polygon fills only). Implemented Stamp annotations. Implemented Named link actions. Fixed a really dumb bug in the TrueColor code in SFont (which affects both Type 1 and TrueType font rendering on 16-bit displays). Rewrote the GfxColorSpace / GfxColor code. Switched from djgppcfg to dj_make.bat (from Michael Richmond). Bug in the Type 1 encoding parser -- couldn't handle lines of the form 'dup NNN/name put' (with no space between the code and the name). Fixed the mkstemp() test in configure.in -- switched from AC_TRY_COMPILE to AC_TRY_LINK and added . Added DESTDIR to top-level Makefile.in. Fixed an incorrect OPI comment in PSOutputDev. Minor tweak to the CCITTFax code to avoid writing past the end of an array on an invalid data stream. Xpdf crashed if the user selected 'reload' when no document was loaded. Look for character names of the form "xx" (two hex digits with no leading alphabetic char) and 'cNNN' (decimal digits with a leading alphabetic char that happens to be a hex digit). FlateStream didn't correctly handle zero-length streams. Xref reconstruction didn't handle the case where the opening "<<" immediately followed "trailer" with no intervening whitespace. Fix the %%DocumentSuppliedResources comment in EPS output. Scale annotations to fit their rectangles. Added Stream::close() to handle cases (e.g., patterns) where a Stream object is used multiple times before it is deleted. Added the topLevel arg to Gfx::go() so it doesn't call out->dump() for every pattern element (and form). Rearranged the GfxResources class. Clean up white space handling in Lexer. Make the dpi parameter to PDFDoc::displayPage etc. a double - this avoids margin gaps with fit-page and fit-width. Fix a rounding problem in xpdf.cc that was causing the window to sometimes be one pixel too small. Fixed a minor bug in dealing with Base-14 TrueType font names. Fixed Lab -> RGB color space conversion. Added support for opacity values (from PDF 1.4) to GfxState and OutputDev. [Thanks to Leonard Rosenthol.] Implemented type 2 functions; rearranged the Function class hierarchy. 0.91b (2000-oct-29) ------------------- Print a warning about Type 3 fonts (XOutputDev, PSOutputDev). Added the scroll lock behavior to 'n' and 'p' keys in xpdf. Change FileStream buffer size to a #define'd constant. Renamed Pattern to GfxPattern to avoid clashes with Windows and MacOS types. Added CNS (Big5) Chinese font support (CHINESE_CNS_SUPPORT); renamed CHINESE_SUPPORT to CHINESE_GB_SUPPORT. 0.91c (2000-nov-19) ------------------- Fix an endianness problem in the Type 1 font code which resulted in an incorrect display with "-t1lib plain" on big-endian systems. CCITTFax stream decoder will skip over extra zero bits at end of line, even if EncodedByteAlign flag wasn't set. Added Big5 support to pdftotext (with CHINESE_CNS_SUPPORT enabled). Fixed a typo in the CNS/Big5 encoding translation table. Change the form code in PSOutputDev to store images in arrays of strings. The xref reconstruction (for damaged files) now also looks for 'endstream' tags, and the parser uses this information when setting up stream objects. In pdfinfo, convert Unicode chars in the 00xx range into 8-bit chars; print a warning if there are any other Unicode chars. 0.92 (2000-dec-03) ------------------ Fixed %%BeginResource comment (for xpdf procset) in PostScript output. Added "-title" switch and "xpdf.title" resource to set the window title. Check for in addition to . Upgraded the configure script to smr_macros 0.2.4 - this should fix a bug where configure wasn't correctly finding t1lib. 0.92a (2000-dec-17) ------------------- Added 'extern "C" { ... }' in various places for ANSI C++ compliance. Tweaked the code that figures out DPI for fit-to-page and fit-to-width modes. Fixed the image transformation code in XOutputDev -- no more missing lines. Implemented color key image masking in XOutputDev. 0.92b (2001-jan-07) ------------------- Fixed a bug in the error-checking code in the Separation/DeviceN color space parsing functions. [Thanks to Lidia Mirkin.] Added wheel mouse support (mouse buttons 4 and 5). [Thanks to Thorsten Schreiner.] Added preliminary support for FreeType 2 (disabled by default). 0.92c (2001-jun-04) ------------------- Fixed a bug in the new image transformation code. Look for character names of the form "", instead of looking for names beginning with a few specific letters. T1FontFile::T1FontFile wasn't initializing vars, and ~T1FontFile wasn't checking before calling T1_DeleteFont -- this caused crashes if it tried to open a nonexistent font file. Catalog::Catalog didn't set baseURI to NULL early enough. Tweak the check for strings.h in the configure script. Yet another fix for the image rotation code in XOutputDev -- off-by-one problem when upsampling. Handle Type 1/1C encodings when using FreeType 2. Allow FreeType2 to render user-supplied Type 1 base fonts. Opening a new file from full-screen mode tried to scroll. Fixed a bug in GfxFont constructor (missing check for NULL base font name). Don't crash if a Type 1 font's FontBBox is non-integer. Pdfinfo prints page size. Tweak for the alpha hack in T1Font/TTFont: sample the middle pixel instead of the top-left pixel. Automatically activate the text input widget in the find window. Changed a Japanese char code mapping in XOutputDev and TextOutputDev: period was being incorrectly mapped to small circle (end-of-sentence character). Add the 0/+/-/z/w key bindings to control the zoom setting. Fixed ImageOutputDev (pdfimages) to correctly handle inline image masks. Extract ascent/descent info from font descriptor. 0.92d (2001-jun-26) ------------------- Embed TrueType fonts in PostScript output. (Added a "-noembtt" flag to pdftops.) Extract encoding from TrueType fonts. Moved Function classes to a separate file (Function.h/cc). Implemented multi-dimensional sampled Functions. Implemented Type 4 (PostScript calculator) Functions. For Type 0 fonts, FontDescriptor is in descendant font, not parent. [Thanks to Lidia Mirkin.] Added the "-htmlmeta" option to pdftotext. In TextOutputDev, when computing the number of blank lines to insert, do a sanity check on the result. If both FlateDecode and some other filter (e.g., DCTDecode) were applied to an image stream, getPSFilter() crashed instead of just returning NULL. Handle the /Identity function. 0.92e (2001-aug-23) ------------------- Widths in font dict should override built-in font widths. Changed "rotate left/right" menu items to "rotate clockwise/counterclockwise". The link parsing code choked if the Border array was incorrect (too short). Modified PSOutputDev to output CMYK for fill/stroke colors. 0.93 (2001-oct-25) ------------------ Implement PDF 1.4 (128-bit) decryption. Bump supported PDF version number to 1.4. Text output for Simplified Chinese. [Thanks to Cheung Siu Fai.] Read an app-defaults file for Xpdf. Read a system-wide config file (/etc/xpdfrc) if ~/.xpdfrc doesn't exist. Accept and verify owner password; if correct, allow all actions. Added a "-level2sep" option to pdftops to generate Level 2 separable PostScript. The PostScript separation convention operators are used to handle custom (spot) colors. [Thanks to Thomas Freitag for help on this.] Add support for FreeType 2 to the configure script. Warning: this requires FT 2.0.5 or newer. Fixed the bounding rectangle overlap test in the disconnected subpath fill hack in XOutputDev. Stupid typo in font name table in PSOutputDev. Changing the zoom setting with a keyboard shortcut didn't update the displayed setting. Modified the mouse wheel support and added the second wheel (mouse buttons 6 and 7). [Thanks to Michal Pasternak.] Character and word spacing is affected by horizontal scaling (display and PS output). [Thanks to Eddy Ng.] Rotation specified by the text matrix, character spacing, and horizontal scaling interacted incorrectly (display and PS output). Some broken Type 1/1C fonts have a zero BBox -- kludge around this by assuming a largeish BBox. Handle PDF files with an incorrect (too small) xref table size. Allow "-?" and "--help" as aliases for "-h" (all apps). Correctly handle unescaped parens in strings in Lexer. Fixed a bug in LTK where a menu got posted multiple times if you right clicked while a page was being rendered. Removed a comma inside a string in configure.in. Kludge around broken PDF files that use char 32 but encode it as .notdef instead of space. Clean up various compiler warnings: use constructor args like "fooA" if there is a field named "foo". Everything now compiles cleanly under gcc 2.91.66, 2.95.2, and 3.0.1. Page objects now read all of the page rectangles (MediaBox, CropBox, BleedBox, TrimBox, ArtBox), as requested by the pdfTeX folks. Added a new PDFRectangle struct to hold these. Use XOutputDev's Type 3 font size hack in TextOutputDev too, so it does a little better job of extracting text in Type 3 fonts. Modify pdfimages to write one-bit images as PBM files. Work around a bug in cygwin's implementation of fseek. 0.93a (2001-nov-21) ------------------- Implemented the sh (shaded fill) operator for the axial shading type. Minor fixes to avoid compiler warnings. Cleaned up global variables -- moved many into instance vars and function args. Minor fixes for OS/2. Fix the system config file path for VMS. Fix an uninitialized var in XOutputDev that caused crashes on Alphas. Don't incrementally update the display in full-screen mode. For Type 1/1C fonts, use the FontBBox from the PDF FontDescriptor (instead of the one in the font file) if present -- this avoids problems with fonts that have non-standard FontMatrixes. Add the Euro character to WinAnsiEncoding. Track the bounding box of the clip region to make rendering patterns more efficient. Fix openTempFile() for Win32. 0.93b (2001-dec-11) ------------------- Added a duplex option to PSOutputDev and a -duplex switch to pdftops. Added XRef::PDFgetDocInfoNF() for pdftex project. Updated the VMS build script. 0.93c (2001-dec-12) ------------------- Completely rewrote the code that handles font encodings: - everything is Unicode-based - 16-bit fonts are handled much more cleanly - text output encoding can be set more flexibly New .xpdfrc config files. 1.00 (2002-feb-01) ------------------ More work on the font encoding rewrite: - use the ToUnicode font dict entry - pdfinfo and pdftotext (with '-htmlmeta') convert info strings to the selected text encoding Added key bindings for forward ('v') and backward ('b'). Added the pdffonts program which lists the fonts used in a PDF file. Fixed several problems in the TrueType font embedding code (for PostScript output). Accept named destination on command line. Added several new items to pdfinfo: file size, PDF version, tagged (yes or no), XML metadata (with the -meta option). Pdftops didn't get the portrait/landscape setting correct for PDF files with rotated pages. The TrueTypeFontFile class (including the Type 42 converter) now understands cmap format 6. Improved the "about" window -- mention the GPL, add a list of key bindings. Added Zcaron and zcaron characters to WinAnsiEncoding. The '0' keyboard shortcut didn't update the zoom popup menu. Handle the complete list of alternate names for the Base14 fonts. Fixed substitute font scaling in XOutputDev - scale only the width, not the height. Implemented stitching (type 3) functions. Handle the case of moveto/closepath/clip, which defines an empty clipping region. Move dependences into separate Makefile.dep files; get rid of the distdepend target. Move all of the configure-script-generated -D options out of the Makefiles and into a top-level .h file (aconf.h). Cleaned up the FreeType 1/2 detection code in the configure script. Pdfinfo prints dates in a more readable format. Fixed a bug in the Paeth image predictor. Handle annotations with multiple states. Another workaround for buggy X servers: clip points that are way out of bounds. Added libpaper support (for Debian). Generate PostScript DSC resource comments for PS (not just EPS) files. The save and restore (q/Q) operators shouldn't save/restore the path. Performance optimization: disable pattern drawing in TextOutputDev. 1.00a (2002-feb-25) ------------------- Added an optimized special case for one-bit images in XOutputDev. Implemented CID TrueType font embedding; added a psEmbedCIDTrueType option. The initialZoom X resource was broken. The reverse MacRoman encoding should return 32 for "space" (not 202, which is an alternate encoding). Tweaks to the FreeType 2 support: only disable hinting if the bytecode interpreter is disabled (i.e., disable autohinting but not bytecode hinting); add some padding to the glyph cache for CJK fonts. Added level3 and level3Sep options for the psLevel setting and corresponding -level3 and -level3Sep options to pdftops. Added a -level2 option to pdftops for consistency. Avoid a divide by zero in pdftotext. [Thanks to William Bader.] Added a Greek language support package. [Thanks to Alexandros Diamantidis and Maria Adaloglou.] Don't bother trying to extract a "builtin" encoding from a TrueType font. Accept either a page number or a page reference in a link destination. Update the fontFixedWidth flag in GfxFont after reading the char widths (used by the Acorn RiscOS port). Removed yet another (illegal but not caught by gcc) class specified from a .h file. Avoid using snprintf - it's not available everywhere. Improved the CMYK->RGB transform. Use mkstemps where available. 1.01 (2002-may-20) ------------------ Implemented Type 3 fonts. Implemented PostScript CID font embedding; added a psEmbedCIDPostScriptFonts option. Implemented PostScript 16-bit font substitution; added psNamedFont16 and psFont16 options. Moved the initialZoom setting from X resources to the xpdfrc file. Implemented the radial shading type in the sh (shaded fill) operator. [Thanks to Mike Sweet.] Added an 'include' command to the xpdfrc format. Added the displayNamedCIDFontX option so different fonts can be used within one character collection. Added a simple reverse video mode (-rv switch, xpdf.reverseVideo resource). Implemented stroked text in XOutputDev (with t1lib and FreeType2). [Thanks to Leonard Rosenthol.] Implemented stroked text in PSOutputDev. Added a built-in Unicode map for UCS-2. New key binding in xpdf: 'g' activates the page number text field. PSOutputDev will now embed external TrueType fonts in addition to external Type 1 fonts. The psEmbedType1Fonts and psEmbedTrueTypeFonts options were missing the "Fonts" suffix. Documentation in xpdf.1 for -freetype option was wrong. Added the Big5ascii Unicode map to the Chinese-traditional support package (maps 7-bit ASCII straight through). [Thanks to Lawrence Lai.] Modified the EUC-CN and EUC-JP encodings to pass 7-bit ASCII straight through. [Thanks to Lawrence Lai.] Avoid a divide by zero in XOutputDev. [Thanks to Simon Burge.] Remove old code in openTempFile that removed an extension from the name returned by tmpnam. Tweak the scrolling behavior when switching pages. [Thanks to Case Jones.] In the code that guesses character names (for font subsets), also handle names of the form 'ABnnn'. [Thanks to Colin Granville.] Fix the transform code for annotations. Improved the CMap file parser to handle more general PostScript lexical conventions. Added '-enc' option to pdfinfo. Added the small caps and oldstyle numbers from Adobe's Unicode corporate use area to the Latin1 and ASCII7 Unicode maps. The code in TextOutputDev that guesses Type 3 font size could generate a zero size, which resulted in div-by-zero errors. Various tools (including Adobe's) occasionally embed Type 1 fonts but label them Type 1C - so check for a '%!' at the start. Some tools embed Type 1C fonts with an extra whitespace char at the beginning - just skip over it. Fixed a typo in the Simplified Chinese add-to-xpdfrc file. Updates to dj_make.bat and the djgpp build instructions. Added a Turkish language support package. Updated VMS build scripts. [Thanks to Martin Zinser.] Modify the incremental display update code to redraw less often if most of the commands are vector graphics, as opposed to text and images. Tweak the Type 1 font bbox code to look at the bboxes in both the PDF font object and the embedded font file. Fixed the ETenms-B5-H CMap file (for traditional Chinese) to map the Latin characters to their proportional versions. Added an optional displayCIDFontX entry for one of the Arphic TrueType fonts in the traditional Chinese 'add-to-xpdfrc' file. Remove leading '-' on include statements in Makefiles. Added psASCIIHex parameter. Added the GBK Unicode map to the simplified Chinese language pack. Pdftotext now opens the text file in binary mode to avoid Microsoft's annoying automatic end-of-line translation stuff. Added an executeCommand function in goo/gfile.cc. [Thanks to Mikhail Kruk.] The %ALDImagePosition OPI comment was wrong if the page was scaled to a different paper size. The OPI code was saving the default transform matrix before calling setpagedevice, which can change the matrix. Fixed a crash when an inline image dictionary contains garbage. Upgraded to autoconf 2.53. Use unsigned int file offsets, to allow access to PDF files in the 2-4 GB size range; use fseek64/ftell64 if available. Fixed two floating point exception cases that came up with broken PDF files. Avoid a crash when printing an error message regarding an unnamed font. Default link border width should be 1. [Thanks to Michael Pfeiffer.] Minor tweak to build with FreeType 2.1.0. Handle "weird" characters in PostScript font names. PSOutputDev now handles PostScript XObjects. Added several more page attributes for the pdftex project. Transferred the copyright to Glyph & Cog, LLC. 2.00 (2002-nov-04) ------------------ Switched to the Motif toolkit. Support multiple open documents (in separate windows). Added document outlines to the viewer. Modified the text extraction (placement) algorithm. Implemented the JBIG2 decoder. Added a Latin2 language support package. Added support for movie annotations. Switched back to native LZW decompression code. Text extraction from Type 3 fonts was (partly) broken. The owner password checking code was missing a step in the case of 128-bit encryption. Added the 'printCommands' option to the xpdfrc file. Added key binding for '?' to bring up the about/help dialog. In TextOutputDev, ignore any text that's outside the page bounding box. Text extraction throws away "tiny" characters after the first 20000 per page, to avoid really slow runtimes with PDF files that use special fonts to do shading or cross-hatching; added the 'textKeepTinyChars' option to disable this behavior. Text extraction discards duplicated text (fake boldface, shadow effects). Added ctrl-F as a key binding for find. Added a "find next" function, bound to ctrl-G. Added ctrl-P as a key binding for print. Modified the DCT decoder to handle progressive and non-interleaved JPEG streams. Added key bindings for ctrl-Home and ctrl-End. Allow the initialZoom setting to be made in either the xpdfrc file or as an X resource. Added a Hebrew language support package. [Thanks to Roy Arav.] The "make distclean" target now creates (empty) Makefile.dep files in the three subdirectories. Initialize XRef::ownerPasswordOk. Correctly handle stroking of Type 3 fonts in PSOutputDev. Generate correct PostScript for fonts with "weird" character names (e.g., "("). Generate correct PostScript for images using Indexed color spaces with DeviceN base color spaces. Added lowercase Roman numerals to ISO-2022-CN.unicodeMap (simplified Chinese support package). Tweak the image scaling code to better handle flipped (top-bottom and/or left-right) images. Generate correct PostScript code for inline images and images in Type 3 fonts which are too large for a single PS string. Correctly handle indexed color spaces whose base color spaces have component ranges other than [0,1]. Optimized the DCT decoder. Fixed mistakes in the list of key bindings in the about/help dialog. Optimized the Flate decoder. Add literal names for punctuation and digits to the Unicode name table. Cygwin's popen wants mode "r", not "rb". Fixed a bug in the Type 4 function parser (the "if" operator wasn't parsed correctly). Fix a bug in PS output for TrueType fonts with no PDF encoding. Make the bbox size in FTFont more liberal (to avoid problems with fonts that have incorrect bboxes). Reverse the colors in PBM files generated by pdfimages, so the common case (an image mask filled with black) comes out correct. Add fseeko/ftello support which is basically identical to fseek64/ftell64. [Thanks to Nassib Nassar.] Modified column assignment in text extractor to account for characters that convert to multiple characters in the output encoding. Fix TrueType fonts which have an incorrect cmap table length. Work around a pragma bug in the version of gcc that ships with MacOS X 10.2. [Thanks to Frank Siegert and Andrew Stone.] Fix a problem that was causing an infinite loop when a damaged content stream contains an 'ID' command inside a dictionary. Handle the case where systempapername() returns NULL (libpaper support). Handle fonts which are defined directly in the font resource dictionary rather than as separate objects. Track process colors in Level 1 separable PostScript. Pdfinfo now checks the return value from mktime to avoid seg faults in flakey strftime implementations. If duplex is not enabled in PostScript output, leave the duplex setting alone, allowing the spooler to insert its own setting. Added three missing fclose calls. Change the default encoding for TrueType fonts (used when the PDF file doesn't specify an encoding) from MacRomanEncoding to WinAnsiEncoding. Move X_CFLAGS to the end of the list in CXXFLAGS (in Makefile.in) to avoid some of the FreeType2 include path problems. Fixed an obscure bug in the LZW decoder. [Thanks to Martin Schroeder.] Fixed a bug in decryption when using the newer (PDF 1.4) algorithm with shorter-than-128-bit keys. Minor optimization for image data streams: the ImageStream class can return an entire buffered line. 2.01 (2002-dec-05) ------------------ Redesigned the text extraction process: - process the text into "reading order" - added a "-layout" flag to pdftotext to switch back to the old style, where physical layout is maintained - use of the "-raw" flag is no longer recommended Added the -reload option for xpdf (in remote mode). Added support for external CID fonts; added the displayCIDFontT1 and displayNamedCIDFontT1 commands to the xpdfrc file. Handle the case of moveto/newpath/clip, which defines an empty clipping region (just like moveto/closepath/clip). Accept XYZ link destinations with missing array elements. Fix some problems with state save/restore triggered by Type 3 fonts that reference other fonts. Accept bogus font names based on "Symbol": Symbol,{Bold,Italic, BoldItalic}. Fixed color and font resource names in the xpdf man page. Was using delete instead of gfree in OutlineItem::~OutlineItem. Set the busy cursor in the find dialog while searching. Map variants of the copyright, trademark, and registered trademark symbols to the proper Unicode codes, not to Adobe's corporate use area codes. Fixed a floating point exception bug in TextOutputDev (check for a too-small denominator). Fixed a typo in TextOutputDev, in the code that generating blank lines to add vertical whitespace. Config files whose last line didn't end with a LF (or CR+LF) weren't being handled correctly. The code that handled CIDToGIDMaps in Type 2 CIDFonts was broken. Check the per-glyph bounding box in Type 3 fonts, and don't try to cache glyphs with bogus bboxes. Allow ToUnicode CMaps to use fewer than four hex digits in the Unicode char indexes. Added multithreading protection to the GlobalParams class. Fixed a bug in end-of-stream detection with the TIFF predictor. Added some characters to MacRomanEncoding to match up with Apple's definition. 2.02 (2003-mar-24) ------------------ Rewrote the text extractor code that assembles words into lines to better handle vertically overlapping lines. Add the "match" option for paper size (in PostScript output). Added support for external 16-bit TrueType fonts; added the displayCIDFontTT and displayNamedCIDFontTT commands to the xpdfrc file. Added an Arabic language support package. Added the Windows-1255 encoding to the Hebrew language package. A missing NULL check was causing a crash when closing the file in a single window (which clears out the window, but leaves it open). Deal with TrueType fonts whose glyph data is out of order - this affected both FreeType rasterization and PostScript generation. Munge font names in PSOutputDev to avoid names that are problematic for ghostscript because they start with an out-of-limits number (e.g., 1e999foo). Modify the TrueType font encoding deciphering algorithm in yet another attempt to match up with Acrobat's behavior. Bounds check the indexHigh value in indexed color spaces. The text extractor no longer bothers trying to get an average character width for Type 3 fonts, since it generally doesn't work very well (because Type 3 metrics are unreliable). Don't crash if the user hits ctrl-G ("find again") before doing a find. Set the button pixmap foreground color correctly. Handle text drawn backward on 180 degree rotated pages. Added a magic call to XtUngrabButton after calling XmCreatePopupMenu which appears to prevent some very odd problems (idea taken from the DDD source code). Fix the MacOS X fix (needed to include ). Fixed a bunch of Motif 1.x / X11R5 incompatibilities. [Thanks to William Bader and Albert Chin-A-Young.] Fixed various bugs in previously untested code in the JBIG2 decoder. Modify the XPDFCore destructor to avoid a bogus warning message from OpenMotif 2.2. Modified the Type 1C font parser to do proper bounds checking. Fixed the bounds checking in the TrueType font parser. Text extractor shouldn't do block merging in physical layout mode. Fixed a problem in PSOutputDev in level2sep mode with images in a Separation color space and with a non-default Decode array. Text extraction with "-raw" was concatenating lines from the bottom of one column and the top of the next. Handle Type 1C subroutines in the font converters. Correctly handle progressive JPEG images whose scans are slightly different sizes (e.g., the Y scan rounds up to a multiple of 8 pixels and the Cb/Cr scans round up to 16 pixels). Avoid a potential divide-by-zero problem in TextOutputDev. Modified the T1Font and FTFont modules to correctly handle glyphs that are larger than the font's claimed bounding box. Tweak dupMaxDeltaX parameter in TextOutputDev to avoid triggering on double characters. Improved detection in pdfinfo for ISO paper sizes. [Thanks to Hartmut Henkel.] Xpdf wasn't responding to the TARGETS atom, which prevented pasting the selection into various applications. [Thanks to Phillip Ezolt.] Handle XObjects with recursive references in their Resources dictionaries (in PSOutputDev). Change PSOutputDev to deal with invalid PDF files that use non-embedded TrueType fonts with no encoding. Check for undersized Widths arrays in fonts. Add bounds checking code to Array class. Updated VMS build scripts. [Thanks to Martin Zinser.] Tweak the TrueType font handling code (again): - char codes in symbolic fonts may or may not be offset by 0xf000 - discard empty tables because they sometimes confuse FreeType Fixed bounds checking in the Flate decoder. Removed a bogus error message for exponential functions without explicit C0/C1 values. [Thanks to Hartmut Henkel.] Handle the other Unicode cmap type (platform=0) in TrueType fonts. Added support for the SGI Motif horizontal paned window widget. [Thanks to Felix Ritter.] Ignore extra elements in link destination arrays. Accept external Type 1 font files with a suffix of ".ps" or no suffix at all. Add a bounds check in the DCT decoder. Added instructions for building xpdf.exe under cygwin/XFree86. Tweaked the word separation parameter for raw-mode text extraction. 2.03 (2003-oct-10) ------------------ Rewrote the text extractor to: - do a better job with rotated text; - handle right-to-left scripts; - be faster. Changed the zoom setting to use a percentage (relative to 72 dpi) instead of a zoom "factor". If the PDF file has an outline, open the outline pane initially. Added -f and -l options to pdfinfo; print multiple page sizes. The HAVE_XTAPPSETEXITFLAG test in XPDFApp.cc was backwards. The BitsPerComponent entry is optional in image mask objects. Render any annotation with an appearance stream, instead of just Widget and Stamp annotations. Fix a bug in the TrueType font checker: the test for an unsorted 'loca' table was wrong. Modify the TrueType cmap selection algorithm yet again to try to match Adobe's behavior. Changed sqrt(2) to sqrt(2.0) in pdfinfo.cc to make various compilers happy. Fixed a deadlock problem (when MULTITHREADING is set); cleaned up some other problems with the locking code. Fixed a bug in the interpolation code for type 0 (sampled) functions. Implemented type 1 (function-based) shaded fills. Fixed some stupid bugs in the JBIG2 decoder (introduced with the previous optimization work). Fixed a typo in the code that parses vertical font metrics for CID fonts that was causing a seg fault. Fixed a couple of bugs that were causing seg faults with badly damaged PDF files. Limit the number of nested Forms to avoid infinite recursion (in buggy PDF files). Add a special case for rectangular clip regions - make sure these don't drop pixels on the right and bottom edges. Tell FreeType not to use glyph bitmaps when in anti-aliased mode. Read all of the border style info for links. All of the shaded fill types now do at least one bisection to avoid problems when the colors at the endpoints of the domain are the same. If the Length2 parameter for an embedded Type 1 font was incorrect (too small), pdftops was losing font data. Deal with (broken) DCT streams that use the same component ID number for different components. The MediaBox page attribute was not being inherited correctly. Fixed a bug in the Type 1C font converter related to local subroutines. The Type 1C -> Type 1 font converter was allocating the font dictionary one slot too small. Added a missing private dictionary entry to Type 1 fonts generated by the Type 1C converter. [Thanks to Michael Shell.] Fixed bugs in the tiling pattern fill code. Try the TrueType 0xf000 char code offset hack for the MacRoman encoding too (in addition to MS Symbol). Update the font metrics info for the Base 14 fonts to include the Euro character. SECURITY HOLE: Escape various characters in URLs before running a web browser (or movie viewer). [Fixed in 2.02p11] SECURITY HOLE: In the dialog used to verify "launch" links, provide a scrolling view if the command to be run is excessively long. [Fixed in 2.02p11] Added an option to disable insertion of page breaks (form feed characters) in extracted text (pdftotext -nopgbrk; xpdfrc "textPageBreaks" option). Check for 8-bit fonts that specify an out-of-range FirstChar or LastChar. Correctly handle an obsolete Type 2 charstring op (in the Type 1C-to-Type 1 font converter). [Thanks to Helge Blischke.] Use the font encoding info to fill in holes in the ToUnicode map. Added character names for Bulgarian (in the Cyrillic support pacakage) and Greek. Handle clipping to text in xpdf and pdftops. Fix color space detection in DCT decoder. [Thanks to Dwight Kelly.] Added the "unicodeToUnicode" xpdfrc option, intended (initially) for Arabic support. Handle the case in PSOutputDev where two font objects refer to the same embedded TrueType font, but with different encodings. [Thanks to Frank Siegert.] Kill any pre-existing path before drawing a form (or annotation). Save state before rendering page content; restore state afterward. Fix Stream::reset/close to work correctly with encoder streams; fix PSOutputDev to use Stream::close consistently. Fix a seg fault when hitting the 'back' button after closing a file. GfxState::getStrokeGray was returning the fill gray value (this only affected Level 1 PS output). Change PSOutputDev to reuse dictionaries in Level 1 mode (since Level 1 PS interpreters don't do garbage collection). [Thanks to Frank Siegert.] PSOutputDev was generating incorrect translations for landscape-mode pages. Implemented shading pattern color spaces. PSOutputDev wasn't correctly handling Type 3 fonts which used image resources (as opposed to inline images). [Thanks to Frank Siegert.] The fix from 1.00 which clipped out-of-bounds points was a bit too aggressive. Do proper Floyd-Steinberg dithering in XOutputDev. Don't automatically check for a null owner password (to match Adobe's behavior). Allow the FlateDecode filter in Level 3 PostScript output. Fixed small bugs in the Type 1C -> Type 1 converter and Type 1C -> Type 0 converter. [Thanks to Tom Kacvinsky.] Work around another weird Motif problem with the right button menu (which was sometimes causing the menu to not be displayed). Make the code that handles fonts defined directly in the resource dict more robust. Add a brief description of the outline pane to the xpdf man page. Ignore extra operands to content stream operators. Fixed a bug in the CCITTFax decoder. Allow the Count entry in a Pages dictionary to be a real number (because some PDF generators actually do this). Shading pattern fills weren't being clipped correctly. Incorrect shallow copies in GfxRadialShading and StitchingFunction. The StitchingFunction destructor wasn't checking for funcs being NULL. Change the TrueType code-to-GID mapping code so it looks at the TrueType 'post' table. Set the print command in the print dialog once at startup, don't change it each time a file is (re)loaded. Generate the %%BoundingBox comment in regular PostScript files (not just EPS files). Fixed a bug in the Unicode CMap parser. 3.00 (2004-jan-22) ------------------ New PDF rasterizer ("Splash"). Added support for PDF 1.5: - JPX (JPEG 2000) decoder - XRef streams - object streams - DeviceN color spaces with up to 32 components - Added new CMaps to the CJK language support packages Replaced pdftopbm with pdftoppm (which can generate PBM, PGM, and PPM files). Reorganized the font file parser code into a new library ("Fofi"). Removed support for FreeType 1.x. Removed support for X server fonts - Xpdf (and pdftoppm) will now search for the URW fonts (from ghostscript). Changed the "-t1lib" and "-freetype" switches; replaced the "t1libControl" and "freetypeControl" config file options with "enableT1lib", "enableFreeType", and "antialias". Added the "-box" option to pdfinfo. Added imageable area support to PSOutputDev (for CUPS); added the "psImageableArea" config file option. Added the "-nocrop", "-expand", "-noshrink", and "-nocenter" switches to pdftops; added the "psCrop", "psExpandSmaller", "psShrinkLarger", and "psCenter" config file options. Dictionary size was in PostScript code generated for Type 3 fonts. The PS code generated for images in Type 3 characters was broken. Tweaked the text extractor. Accept xref entries that are one byte too short (matching Adobe's behavior). Change things so "xpdf -h" and "xpdf -v" work if DISPLAY isn't set. Fix a problem in the damaged file repair code that handles the trailer dictionary. Use the "Last" entries in "Outlines" objects - this avoids a problem with PDF files generated by buggy software that, e.g., sets the last item's Next pointer to point to itself. PSOutputDev was not handling DeviceN color spaces correctly in Level 2 images. Fixed a stupid little bug that broke PS output for JBIG2 images. Work around a Lesstif bug: set up an extra callback so hitting in the find dialog performs a search. [Thanks to Elliott Hughes.] Pdftops was crashing on zero page PDF files. Add an AC_PREREQ call to configure.in. Change the 'find' dialog so the text entry box resizes with the dialog. Skip extraneous zero bits at the start of a CCITTFax stream. The PostScript text clipping operator was missing a 'newpath'. [Thanks to Frank Siegert.] Fix a bug in tiling patterns with bboxes that don't start at (0,0). Fix a bug in Type 3 font handling with rotated text. The tiled pattern fill code was destroying the current path, which broke the fill+stroke operators when the fill color space was a tiled pattern. ICCBased color spaces don't always set their Ranges values correctly, so just use the values from the alternate color space. Modified GHash to accept int or void* - this avoids some conversion warnings. Check for missing Type 3 CharProcs - avoid a segfault. Pdffonts now marks all Type 3 fonts as embedded. Outline entries with no Title string weren't being handled correctly, resulting in segfaults. PSOutputDev now forces the text horizontal scale factor to be non-zero to avoid singular font matrices in the PS code. Tweaked the error recovery in the CCITTFax decoder. The LZW/Flate predictor should treat any Predictor value (in the stream dictionary) >= 10 identically. PSOutputDev and pdffonts check for NULL font objects (which can happen, e.g., because of missing CMap files). Swap the left and right mouse wheel button numbers. EPS output ("pdftops -eps") now uses the CropBox instead of the MediaBox as the EPS bounding box. 3.01 (2005-aug-17) ------------------ Added the continuous view mode, including the '-cont' switch and the 'continuousView' config file option. At high zoom levels, don't rasterize the entire page - this avoids problems running out of memory. Added "search backward" and "match case" options to the find dialog. Support explicitly masked images and soft masked images. Add support to DCTStream for 16-bit quant tables. Don't segfault if the user clicks on an outline entry with a broken destination. Changed the makefiles and configure script to skip building pdftoppm (in addition to xpdf) if X, Motif, or FreeType is not found; changed the error message in the configure script to match. Move an inline function in JArithmeticDecoder.cc to avoid compiler errors. Fixed a bug in the rasterizer that was sometimes causing infinite loops with round line caps on vertical lines. Various rasterizer optimizations. Look for intermediate resize events - try to avoid lagging when the user is doing an opaque resize. The FormType key in Form XObjects is optional. Handle external 16-bit TrueType fonts correctly, using the Unicode cmap. Add class declarations to TextOutputDev.h to work with stricter C++ compilers. Support FreeType's weird include file stuff (ft2build.h, etc.). Fixed a bug handling empty paths. Fixed a text positioning problem in PostScript output. Handle TrueType collections in FoFiTrueType.cc. FoFiTrueType constructor was reporting a failure if the post table was bad - this should be non-fatal. Type 1 font parser was missing a NULL test. Mask chars passed to isdigit in goo/parseargs.c to avoid problems with signed chars. Added more error checking to the CCITTFax decoder. Fixed a bug (computing the MCU size) in the DCT decoder. Change a test in the Splash stroke code to avoid x86 floating point weirdness. Reorganized the decryption code to allow security handler plugins; removed the NO_DECRYPTION #ifdefs. Added a plugin interface, initially just for security handlers. Support color key masked images and explicitly masked images in PS output (Level 2 only). When checking for aliases of the Base 14 fonts, ignore spaces in the specified font name. Handle encrypted PDF files that are missing the file ID string. Handle tiling patterns more efficiently in the PostScript output. Rewrote the code that handles color spaces in PostScript output. Fixed a bug in the Type 1C font parser - zero-length indexes (and zero-length names) weren't handled correctly. Handle shaded fills more efficiently in the PostScript output. Implement the remaining shading types (4-7). Rearranged the Splash color modes. Add the EarlyChange parameter to LZWStream when generating PostScript. Check for zero values in line dash arrays in PSOutputDev. Fixed an uninitialized variable in JArithmeticDecoder which was causing crashes. Treat unknown CMap names as identity mappings (to match Adobe's behavior). Fixed bugs in the XRef parser related to XRef streams in updated files. Added a missing call to FT_Done_Glyph which was causing a memory leak. [Thanks to Dave Formanek.] Fixed a bug in text copying that was causing the last word to be dropped on some pages. Tweaked the image width/height computation in Splash::drawImage and Splash::fillImageMask to make striped images work better. Ignore minus signs in the middle of numbers (to match Adobe's behavior). Missing '%s' in format strings for dates in pdftotext '-htmlmeta' mode. Change the TrueType code-to-GID mapping code so it looks at the standard name-to-Unicode mapping before the ToUnicode mapping defined in the font object. Added a matteColor setting (command line option and X resource). Tweaked the CMYK->RGB transform. Fix some problems in tracking the character position (to match up with Adobe's highlight file format). Handle moveto/closepath/stroke correctly. Check for singular text matrices and font size of zero in PSOutputDev. Clip PS output to the size of the page (avoiding any gibberish that lies outside the MediaBox, in the case where the MediaBox is smaller than the paper). If the line dash element in an annotation's Border array is of an invalid type (i.e., not an array), don't draw the link at all (this matches Adobe's behavior). Don't remap small caps and oldstyle glyphs in the name-to-Unicode table - it messes up TrueType font encodings. Pdftoppm wasn't setting the paper color correctly in mono and gray modes (this only showed up on big-endian machines). Missing NULL check was causing crashes when attempting to read non-PDF files that happened to contain the string '%PDF'. Fixed a problem in the text extractor that was breaking up words. Handle vertical text (CJK fonts) in PS output with TrueType fonts that are missing the vertical metrics tables. Handle the case where a font object and the corresponding embedded font are different types. Handle basic crypt filter functionality. Added more value checking in the XRef parser, to avoid potential security problems. Updated the CJK language support packages: replaced the displayCIDFontX references with displayCIDFontTT; added pointers to free TrueType fonts. Added a missing error message when SplashOutputDev can't parse an embedded TrueType font file. PDFCore and TextOutputDev now correctly handle searching for Unicode strings, including real Unicode case-folding. Throw away tiling pattern fills that are completely outside the clip region. The JPEG 2000 inverse reversible multiple component transform code was wrong. Fixed some bugs in shading pattern fills: clipping was wrong, and background color was not implemented. Added tool tips for the toolbar buttons. Decrease the max depth of recursive patch mesh filling if the pattern has a large number of patches. Highlight the find text whenever the find dialog is mapped. Handle page boundary boxes with reversed coordinates. Fixed a bug in the text extractor code that handles duplicated text. Optimization work on SampledFunction::transform(). Use the CropBox instead of the MediaBox as the display region. Dither for PseudoColor (8-bit) displays. Fix a bug in DCTStream that was causing an infinite loop with corrupted DCT image data. Fix a bug in the ToUnicode CMap parser. Fix a bug in the text extractor - negative font sizes weren't being handled correctly. Fix a bug in the text extractor - in certain cases, out-of-bounds text could cause crashes (generally only in damaged PDF files). Fix a read-past-end-of-array bug in the JBIG2 decoder. Fix a case where pdftops was generating lines longer than 255 chars. Optimize redraws - don't regenerate the XImage every time redrawRect is called. The ASCII85 decoder wasn't skipping whitespace properly. Optimize text extraction: skip (non-inline) image setup entirely. Added initial transparency support (stroke/fill alpha and blend mode). Added support for the overprint setting in PostScript output. Fixed various buffer overflow bugs. Handle negative font sizes and horizontal scaling correctly - this affected PSOutputDev for all text operators, as well as the TJ operator for all OutputDevs. Fixed a buffer overflow in the CCITTFax decoder. Fixed an out-of-order entry in the list of font name aliases. Fixed a backward loop in the PostScriptFunction code. Treat a zero-length base URI the same way as a nonexistent base URI. Add a divide-by-zero check in TextOutputDev (the problem was happening in cases of mixed horizontal and vertical text). PSOutputDev wasn't rounding the page bounding box coordinates correctly. Support the SOF1 marker in DCT (JPEG) image streams. Minor changes to GlobalParams.h and JPXStream.h because some compilers don't like anonymous structs inside anonymous unions. Xpdf now complains about a negative page number. Changed GString::cmp and GString::cmpN to correctly handle '\0' chars in the middle of strings. Fixed the radial shading code; corrected the handling of the 'extend' parameters. Added the gmallocn and greallocn functions. Fixed a bug in the TIFF image component predictor which shows up with components that are not 1 or 8 bits wide. Optimized FlateStream::loadFixedCodes(). For non-embedded Base-14 fonts, don't use the ascent/descent/bbox values from the FontDescriptor - various PDF generators get them wrong. Fixed a bug in the text extractor - words on the same line (especially in tables) were being split vertically onto multiple lines. Automatically select the correct radio button ("print with command" vs. "print to file") in the print dialog. Don't create the "open" and "save as" dialogs until needed - this avoids stat-ing every file in the directory at startup. Changed the Big5 and Big5ascii encodings (in the traditional Chinese language support package) to include characters from the Unicode database (which aren't mentioned in the Adobe character collection documentation). Added the '-pagecrop' switch to pdftops. Tweaked the RGB->gray and CMYK->gray conversion functions to match the PDF spec. The JPEG 2000 decoder wasn't correctly handling codeblocks split across multiple packets/layers. Fixed a typecast that caused compile errors on 64-bit systems. The CMap parser wasn't handling the 'cidchar' construct. Handle the case in PSOutputDev where two font objects refer to the same embedded 16-bit TrueType font, but with different CIDToGIDMaps. Changed the configure script to report more accurate warnings when it can't find X / Motif / FreeType. Encryption with revision=2 always uses a 40-bit key, regardless of the specified Length value. Yet another minor change to the TrueType font encoding deciphering algorithm. Don't completely invalidate the Catalog if one (or more) of the page objects are bogus -- just skip over those pages. Removed the workaround in pdftops for too-small Length2 values in Type 1 fonts -- it was causing problems on various PostScript printers. Started adding error checking to the JBIG2 decoder (this is nowhere near complete yet). Extended the "unicodeToUnicode" config option to also apply to CID fonts. Added the narrow Latin characters to the Adobe-Korea1.cidToUnicode file in the Korean language support package. Fixed the code that handles page rotation in PSOutputDev. When converting a Type 1C glyph to a Type 1 glyph, insert closepath operators as appropriate. Check for a sane 'loca' table in TrueType fonts (FoFiTrueType::parse). Fix PSOutputDev to correctly handle the case of an empty name in a font encoding. 3.02 (2007-feb-27) ------------------ Added anti-aliasing for vector graphics; added the vectorAntialias xpdfrc option; added the "-aaVector" switch to xpdf and pdftoppm. Implemented stroke adjustment (always enabled by default, ignoring the SA parameter, to match Adobe's behavior), and added the strokeAdjust xpdfrc command. Support PDF 1.6 and PDF 1.7. Added support for AES decryption. Added support for OpenType fonts (only tested with 8-bit CFF data so far). Added user-configurable key/mouse bindings - the bind/unbind xpdfrc commands. Cleaned up the full-screen mode code and added the ability to toggle it on the fly (the default key binding is alt-f). Pdfimages with the -j option now writes JPEG files for 1-component (grayscale) DCT images, in addition to 3-component (RGB) images. Fixed bugs in handling sampled (type 0) functions with 32-bit samples. Fixed some things to support DeviceN color spaces with up to 32 colorants. Pdftops now constructs the %%Creator and %%Title DSC comments from the relevant information in the PDF Info dictionary. Tweak the TrueType font encoding deciphering algorithm. Added the "mapUnkownCharNames" xpdfrc option. Fix a bug (that only showed up with certain window managers) in the intermediate resize event optimization. [Thanks to Michael Rogers.] Check for a broken/missing embedded font (this was causing xpdf to crash). Added support for transfer functions in PostScript output. Be a bit more tolerant of Link destinations that contain null values for positioning parameters. Use ordered dot dithering instead of clustered dot dithering at resolutions below 300 dpi (for monochrome output). Fixed security holes (bounds checking issues) in several places. Don't bother creating a SplashFont (allocating memory) for fonts that are only used for hidden text - this avoids problems with fonts of unreasonably large sizes. Clipping in TextOutputDev was off for characters on the left edge of the page. The scn and SCN operators weren't correctly handling colors with more than four components. FoFiType1::writeEncoded wasn't always correctly finding the end of the encoding. Use the ColorTransform parameter in the DCTDecode stream dictionary. Type 3 fonts are allowed to have a bbox of [0 0 0 0], which means "unspecified" -- don't issue error messages in that case. Perform the transform (to device space) in Splash instead of in SplashOutputDev -- this is needed to correctly handle round joins and caps on stroked paths. PSOutputDev now rasterizes any pages that use transparency. Limit the crop, bleed, trim, and art boxes to the edges of the media box (per the PDF spec). Change GString to increase the allocation increment by powers of two. Handle whitespace in hex strings in CMap files/streams. Use strings instead of names for separation colorant names in PSOutputDev. For explicitly masked images where the mask is higher resolution than the image, use the soft mask code. Avoid problems with very large x-steps in the PostScript output for tiling pattern fills. Avoid a divide-by-zero in stitching functions which have a subfunction with empty bounds. Honor the "Hidden", "NoView", and "Print" flags on annotations. Rewrote the pixel rendering code in Splash to use a single set of pixel pipeline functions. Added support for transparency groups and soft masks. Fixed the transparency blend functions to match the addendum published by Adobe. Changed Splash/SplashBitmap to store alpha in a separate plane. Setting the color space now selects the correct default color for that color space. Remove the mutex lock from GlobalParams::getErrQuiet() to avoid a deadlock when parseCIDToUnicode() or parseUnicodeToUnicode() calls it from inside a locked section. Added error checking (on the argument count) in the sc/SC/scn/SCN operators. Skip over notdef glyphs in TrueType fonts (which sometimes get drawn as little boxes), to match Adobe's behavior. Painting operations in a Separation color space with the "None" colorant or a DeviceN color space with all colorants set to "None" never mark the page. Fixed an obscure bug in the JPX decoder - it wasn't reading the extra stuffing byte in the case where the last byte of a packet header was 0xff. Change the TrueType font parser (FoFiTrueType) to change the glyph count rather than report an error if the 'loca' table is too small. Fixed a couple of bugs in the JBIG2 decoder. Added stochastic clustered dot dithering. Added the screenType, screenSize, screenDotRadius, screenGamma, screenBlackThreshold, and screenWhiteThreshold xpdfrc settings. PSOutputDev now correctly handles invalid Type 3 charprocs which don't start with a d0 or d1 operator FreeType 2.2.x support - get rid of the FT_INTERNAL_OBJECTS_H include, and add some 'const' declarations. Handle PDFDocEncoding in Info dictionary strings. Tweak the xref repair code - ignore whitespace at the start of lines when looking for objects. Added the "-exec" switch to xpdf. Removed the xpdf.viKeys X resource. Changed the color key / explicit masked image code in PSOutputDev to generate better PS code, including a Level 3 option. Tweaked the DEBUG_MEM code for performance. Move the JBIG2 global stream reading code into reset() instead of the constructor - this way, pdftotext doesn't end up reading the global stream. Added the "-preload" option to pdftops and the psPreload xpdfrc command. Added the "zoom to selection" command (on the popup menu). Fix a bug (in xpdf/pdftoppm/pdftops) with tiling patterns whose bbox size is different from their xStep/yStep. Implemented stroke with pattern color spaces. Following a link to a page whose CropBox was different from the MediaBox was resulting in an incorrect scroll position. Parse truncated date strings from the Info dictionary correctly. Change FoFiType1 to handle Type 1 fonts with two /Encoding keys. Extend the PSOutputDev shaded fill code to handle DeviceCMYK shaded fills in level2sep and level3sep modes. Detect infinite loops in the Page tree. Optimized the ASCII85Encoder code. Tweaked the text extractor to do a better job of lining up rows of text. Leave images compressed (or re-compress them with RLE) in PostScript output when setting up images for forms and Type 3 fonts (or with -preload). Extend FoFiType1 to handle Type 1 fonts with octal character codes in their encodings. Use a custom string formatter to avoid problems with locale-based decimal formatting (commas instead of periods) in PS output. Allow comments in PostScript-type functions. Change the TrueType font parser (FoFiTrueType) to delete glyf table entries that are too short. 3.03 (2011-aug-15) ------------------ Added the "fixed pitch" text extraction mode. Modified "pdftops -paper match" to handle PDF files with different-sized pages, i.e., it will now select the matching paper size on a page-by-page basis. Add ability for pdftoppm to write to stdout. Added the pdfdetach tool. Implemented 256-bit AES decryption. Commented out the t1lib section in the configure script -- t1lib has some potential security holes, and hasn't been updated in years. Redesigned the font configuration xpdfrc commands: removed the displayFontT1, displayFontTT, displayNamedCIDFontT1, displayCIDFontT1, displayNamedCIDFontTT, displayCIDFontTT, psFont, psNamedFont16, and psFont16 commands; added the fontFile, fontFileCC, psResidentFont, psResidentFont16, and psResidentFontCC commands. Switched from GPLv2 to dual v2/v3 licensing. Performance: cache tiling patterns. Implemented text fills with pattern color spaces. Rewrote the image and image mask rendering code to be more accurate and faster. Fixed a bug in PDFCore that could sometimes cause crashes at high zoom levels. Implemented embedded CMap streams. Added the 'setSelection' command. Added the 'rotateCCW' and 'rotateCW' commands. Added the 'psFontPassthrough' xpdfrc command. Added the 'launchCommand' xpdfrc command. Implemented alpha-type soft masks. Added "Form: AcroForm|XFA|none" to pdfinfo output. Added support for image masks filled with pattern color spaces. Text search wasn't finding all occurrences of a string on rotated pages (i.e., pages where the primary rotation, as displayed, was not horizontal). The text extractor now uses "ActualText" spans if they are present. Modified PSOutputDev so it always check for transparency; if Splash is not available, it now prints a warning. Handle the blending color space for soft masks. Added the disableFreeTypeHinting xpdfrc option. Added the psAlwaysRasterize xpdfrc option. Added support for transfer functions in the rasterizer. Optimized the JPEG 2000 decoder to use less memory. Do fill adjustment (similar to stroke adjustment) on simple rectangular fills. Added the antialiasPrinting xpdfrc setting. Added '%i', '%j', and '%k' (mouse pointer page and position) to the available options for the 'run' command. Links with the underlined border style were being drawn with the lines over, instead of under, the text. Add #include to XPDFTree.cc (to avoid problems with certain compilers). Change XRef::fetch() to avoid infinite loops caused by odd damage to the xref table (e.g., where a stream object's "Length" value is an indirect reference that points to another stream object). Minor fix in GString.cc to deal with an error in newer C++ compilers (pow() can take int or double args). Handle embedded fonts which are declared with the wrong font type, including 8-bit fonts declared as CID fonts and vice versa; this was causing various problems, including crashes and invalid PostScript output. In text extractor, don't drop horizontally overlapping words onto a separate line. The numbers in the operand to the TJ operator should be multiplied by the current horizontal scaling parameter. Fixed a bug in the Type 1C-to-Type 1 font converter -- need to escape strings in the font dictionary. The zero-font-size check in PSOutputDev.cc was broken. Fixes for the form field appearance regeneration code: handle Unicode strings (by downconverting to Latin1); check for "True" in addition to "Yes" as a button value. Modify XPDFTree to limit the widget height to 32767 pixels -- this avoids crashes with very large outlines. Modify FoFiType1 to handle PFB headers in Type 1 font files. Allow image mask decode arrays to be [1.0 0.0] in addition to [1 0]. Tweak the form field appearance regeneration code. PSOutputDev now sets up resources for DR dictionaries in forms (in case the form field appearances are regenerated). For TrueType fonts which are marked symbolic, the cmaps should be ignored. Change the handling of numeric characters in Unicode text output -- they are now treated as left-to-right, which isn't strictly correct, but does result in correct visual formatting. Modify FoFiTrueType to handle bogus loca table entries where the offset is past the end of the glyf table. Fixed shading pattern fills to do clipping and background fills correctly. Change the code that reads the page tree to be more flexible with regard to improperly constructed trees. Changed the PostScript header comment from "Produced by xpdf/pdftops x.yy" to "XpdfVersion: x.yy" to make it (mostly) DSC-compliant. Fixed PSOutputDev to handle page rotation correctly where the PDF page is rotated 90 or 270 degrees and the page width (before rotation) is greater than its height (and vice versa for 0 or 180 degrees). Unbalanced save/restores inside form XObjects (which can be happen in damaged or incorrectly constructed PDF files) could cause crashes. The CCITTFax decoder could go into an infinite loop on certain types of corrupt input. Added the "drawAnnotations" xpdfrc command. Added the "psUncompressPreloadedImages" xpdfrc command. Escape newlines and other non-printable characters in the custom color DSC comments in PostScript output. Added the tilingPatternFill and *ShadedFill functions to PreScanOutputDev to speed it up. Too many elements in an image's Decode array should not be a fatal error. Fixed a buffer overflow security hole in StreamPredictor. Empty pages (zero-length content streams and null contents) were causing crashes in continuous view mode. Handle line dash arrays that start with a zero element correctly. PreScanOutputDev was not correctly detecting all transparency - in some places, it was looking only at the blending mode, and not at the opacity setting. Force halftone screen size to be a power of 2. This allows optimizing the halftoning code. Fixed a bug in the JBIG2 MMR decoder (and also in the CCITTFax decoder) that was causing array references with negative indexes. Fixed a bug in the transparency code that was causing memory overruns. Fixed a 64-bit bug in the ASCII85 encoder. The focusToPageNum was crashing in full-screen mode - it should simply do nothing. Added '%p' (current page number) to the available options for the 'run' command. Tweak the behavior with PDF files that have pages of different widths in continuous mode: scroll horizontally to avoid blank space on the left side (when changing pages via entering a page number or clicking on a link). A closepath followed by a lineto should create a new subpath for the lineto. Fixed a buffer overflow in the CCITTFax decoder. Adobe Acrobat appears to ignore the flatness setting when rasterizing curves, so Xpdf now does the same. (Oddly, Acrobat passes the flatness setting through to PostScript output, which ends up making the PS file look different from the PDF file - so Xpdf continues to pass flatness through to PS files, too.) Pdfimages now ignores tiling pattern fills (for performance reasons). Fixed a bug in PDFCore that could sometimes cause crashes at high zoom levels. Use std::sort (with functors) in place of qsort (if available) - this can be significantly faster. Hitting "close" while Xpdf is in full-screen mode (with only one file open) was crashing. Tweak the TrueType font encoding deciphering algorithm. Rewrote the CCITTFax decoder inner loop - this fixes a security hole. Fixed two security holes (missing bounds checks) in the DCT decoder. Do the correct zooming for "Fit" and "FitR" destinations. Implement the rotation value in the form field appearance regeneration code. When PSOutputDev rasterizes a page (because it contains transparency), the image is broken into stripes if it is above a size threshold. Don't clip the other page boxes to the MediaBox at the intermediate (Pages) nodes; only do it at the leaf (Page) nodes - the other boxes can be specified before the MediaBox is specified. Split several special cases off from Splash::pipeRun, for performance. Add a sanity check for excessively large font sizes (which caused problems because Xpdf tried to allocate memory for a font cache). Fixed a bug in the GfxCIDFont constructor involving reading the vertical metrics. Rewrote the code that handles annotation transforms - it was not handling non-rectangular transforms correctly. Tweak the Type 3 bbox code to allow some slack on the left/bottom edges, as well as the top/right edges. Fixed a bug that was causing problems rendering Type 3 fonts to 1-bit monochrome output. Handle the case where AES padding is invalid. Changed XRef::getNumObjects to return the number of used entries, instead of the same value as returned by XRef::getSize(). Ignore bogus entries in the TrueType table directory instead of immediately giving up on the font. Fixed a bug in the radial shading code that could cause divide-by-zero errors. Tweaked the TrueType font fixup code to deal with an extra zero entry at the end of the loca table. Increased font cache sizes to improve performance. Tweaked the TrueType notdef kludge to skip the notdef glyph only if it was caused by a character for which a Unicode/MacRoman mapping could not be found. Added another font size sanity check, this time for Type 3 glyphs. Added initial support for optional content (layers) - no GUI yet. For CID fonts that specify the 'Adobe-Identity' or 'Adobe-UCS' collection, use an identity mapping for char code-to-Unicode conversion. Updated the error function to take a category argument, and to use GString::format instead of printf; added an error callback. The PDF spec claims that names are limited to 127 chars, but Distiller 8 will produce longer names, and Acrobat 8 will accept longer names -- Xpdf will now handle them, too. Change the Catalog code so it doesn't load the entire page tree at startup (this only helps the command line tools - the viewer scans all of the pages at startup). Clip opacity values to the range [0,1]. Handle glyph names of the form 'unixxxx' (similar to Ann, Axx, etc.). Resolution of rasterized pages in PostScript output was not being computed correctly (resulting in overly large images). Extend the mapUnknownCharNames config command to cover CID fonts. Zero-length segments in the middle of stroked paths were not being handled correctly -- they should be completely ignored, except for the special case of a zero-length path with round line caps. Various optimizations to the Splash rasterizer. Allow "Identity" and "Default" as the transfer function in soft masks. Tweaked the ToUnicode CMap parser to allow <00xx> char codes for 8-bit fonts. TextPage::clear() was not clearing the lists of underlines and links. Changed the CCITTFax decoder to correctly handle the interaction between the EndOfLine and EncodedByteAlign parameters. Fixed a bug where xpdf wouldn't go to a destination specified on the command line, if continuous mode was enabled (xpdf -cont file.pdf +foo). Fixed a bug in the FreeType interface code which was causing incorrect positioning/sizing of characters. Tweaked the FreeType interface code - use 'light' hinting with Type 1 fonts (because it generally looks better). Tweak the Windows font searching code to handle "Black" fonts. Fixed a bug in the PostScript-type function parser -- real numbers that start with a decimal point weren't being handled correctly. Changed the way filled-and-stroked text is handled -- use Splash to do both the fill and the stroke (rather than using the font ending to do the fill and Splash to do the stroke); also turn off stroke adjustment when drawing stroked text. Ignore generation numbers on compressed objects (to match Adobe's behavior). Changed the PostScript PageSize policy from 3 to 6 (choose next largest paper size, don't rescale). Check that the mask values for color key masked images are in range -- both Ghostscript and Distiller choke on the PostScript if invalid mask colors are specified. Fixed a bug in generic region decoding in the JBIG2 decoder. Fixed the lexer to handle large real numbers correctly. Pdftops wasn't correctly handling tiling patterns that use both fill and stroke operators. Report an error if the Size array in a sampled function includes any zeros. The PostScriptFunction.codeString field wasn't being initialized correctly. Invalid object streams were not being handled correctly. Check for loops in xref tables. Handle the case where a content stream ends after the 'ID' operator which starts inline image data. Check for invalid object streams (i.e., an object stream can't be inside another object stream. Add a recursion limit to the object parser - this avoids stack overflows with various sorts of damaged PDF files. Handle various parameter settings in the extended graphics state dictionary. An invalid document outline (missing fields) could cause a crash. Added an overprint preview mode (for CMYK output only). Correctly handle FitH/BH/V/BV link destinations that contain null values for positioning parameters. If the PDF file doesn't define a BaseURI, set one based on the location of the PDF file -- this allows relative links to be handled correctly. Use ResusableStreamDecode when generating Level 3 PostScript for an explicitly masked image. Tweak the Type 1 font parser to handle encodings with multiple characters on one line. Invert subtractive color components before passing them to the blending function. Fix an invalid array access in SplashOutputDev::setSoftMask() in CMYK mode. A PS interpreter may attempt to read past the end of a preloaded image, so we need to check for that. Fixed several overflow/uninit bugs in JBIG2Stream. Fix the CCITTFax decoder to correctly find end-of-file (RTC/EOFB) markers when the EndOfLine parameter is false. Don't limit the startxref offset to 10 digits - some PDF generators use extra leading zeros. Use the "DV" (default value) field in text annotations if the "V" (value) field is missing. Increase the number of digits printed for floating point numbers in PostScript output -- it was running into numerical accuracy problems on large pages. Fixed integer overflow bugs in Catalog.cc and GfxFont.cc. Zero-length tables in TrueType fonts should be treated as missing. ToUnicode CMaps map char codes to Unicode; .cidToUnicode files map CIDs to Unicode -- ToUnicodeCMaps were being handled incorrectly. Added the "psRasterResolution" and "psRasterMono" xpdfrc commands. Added code to FoFiTrueType to check for entries in the table directory with bogus tags -- this handles the case where the number of tables given in the header is too high. Negative shift values in the PostScript bitshift operator were being handled incorrectly. GfxICCBasedColorSpace was not correctly bounds-checking the number of components. Check SampledFunction input values for NaNs. Fix a divide-by-zero when the page width or height is zero. Fix a bug positioning text in PostScript output - if the last char in a string has an incorrect width in the PDF font object, that messes up the total string width, so we have to position individual chars. In PostScript output, if CID font substitution fails, drop all text in that font. Handle PDF files that set the stream/string decryption filters to Identity (i.e., no encryption). Avoid passing a zero font size to FreeType. Tweak raw mode in the text extractor to handle words on the same line drawn in the wrong order. Pdftops was generating a singular transform matrix for annotations whose bounding boxes had zero width or height. Handle embedded OpenType CFF fonts with CIDToGIDMaps. Remove the old kludge from PSOutputDev that was converting char 32 from ".notdef" to "space". Allow CCITTFax images to be more than 32k pixels wide. Modified the CMap parser to handle usecmap with Identity-H/V. Added some parameter checking in the JPX decoder. Added checks for infinite loops in PDF objects - for color spaces, functions, optional content, and outline items. Add support for mouse button bindings up to button 32 (old limit was 7). Fixed a bug in the decryption code for revision 3 with keyLength < 16 -- the owner password was not being handled correctly. [Thanks to Matthias Franz.] Optimize SampledFunction: pull index computation code out of the transform function; cache the last transform. Tweaked the font naming algorithm in PSOutputDev. Treat mirrored (as opposed to rotated) text the same as upright text in pdftotext. Fixed buffer overflows in Splash and SplashBitmap. Check for bogus character codes (e.g., ) in ToUnicode CMaps. The radial shading code (in both Gfx.cc and PSOutputDev.cc) was not computing the s bounds properly. Drop empty subpaths in clip and fill (but not stroke) operations - this can significantly speed up clip performance in the weird case where a PDF file does " re m h W n". Added code to FoFiTrueType to check for an invalid loca format field in the head table. The axial shading code (in Gfx.cc, but not PSOutputDev.cc) was not computing the incremental polygon vertices correctly. Set the character width in TextOutputDev to something sensible for vertical fonts. Added basic support to the text extractor for vertical writing mode. The non-interactive tools (pdftotext, pdftops) now free Page objects after using them, avoiding performance problems with pages that have huge resource dictionaries. Check for line dash arrays like [0], and draw nothing at all (to match Acrobat's behavior). Add a sanity check for the ascent/descent values in FontDescriptors. Single-point paths with a line dash were causing a crash. Correctly handle Level 3 PostScript output with masked images inside patterns. Tweaked the xref repair code so that it runs if the catalog is messed up (in addition to running if the xref table is damaged). If Indexed color space tables (streams or strings) are too small, reduce the max index instead of throwing away the color space. Change the CMap parser to allocate memory only when it sees a mapping, not when it sees a 'codespacerange' declaration -- this avoids allocating huge amounts of memory for CMaps with large, unused codespaceranges. In monochrome mode, treat lines with width <= 1 as hairlines (to match Acrobat's behavior). Cache the last transform for PostScript-type functions. Added the "-rawdates" option to pdfinfo. Optimized ImageStream::getLine(). Fixed the Hue, Saturation, Color, and Luminosity blend functions to match Adobe's spec. Fixed the non-isolated group compositing computation. Skip extraneous unused data at the end of JBIG2 segments. Change the algorithm that stroke/fill adjustment uses so that the edges of adjacent strokes/fills line up. Do stroke adjustment on end caps when cap style is butt or projecting. Fixed a security hole: Gfx.parser was not being initialized to NULL. Fixed a security hole: integer bounds check in the Type 1 encoding parser in FoFiType1.cc. If an embedded font object is invalid or non-existent, do font substitution (same as if there were no embedded font). TextOutputDev was reusing an old font in the case where the font changed but the font size and character positioning stayed the same. When starting a transparency group, copy the fill/stroke colors from the graphics state. Tweaked the fixed-point code. When a TrueType font is declared resident (with a psFont command), don't munge the encoding. Look for URIs starting with "www." and treat them as absolute "http:" URIs, not as relative URIs (to match Adobe's behavior). Added code to FoFiTrueType to check for a zero-entry cmap table. Tweaked the font substitution code to do a better job of scaling the substituted font. Require at least two splits in the axial shading color bisection. Optimized JBIG2Stream::readGenericBitmap(). JPXStream wasn't correctly handling row padding for images with fewer than 8 bits per component. Optimized the ToUnicode CMap parser. Added a "whole words only" option to text searches. Check for valid component parameters in the DCT decoder. Implement embedding of external 16-bit fonts (without subsetting) in PostScript output. Added the minLineWidth xpdfrc command. Added warning messages for font substitutions. xpdf-3.03/aclocal.m40000644000076400007640000002424311622305345013560 0ustar dereknderekn# <<< smr.m4 from smr_macros 0.2.4 >>> dnl ####################### -*- Mode: M4 -*- ########################### dnl smr.m4 -- dnl dnl Copyright (C) 1999 Matthew D.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . xpdf-3.03/Makefile.in0000644000076400007640000000765511622305344013774 0ustar dereknderekn#======================================================================== # # Main xpdf Makefile. # # Copyright 1996-2003 Glyph & Cog, LLC # #======================================================================== SHELL = /bin/sh DESTDIR = prefix = @prefix@ exec_prefix = @exec_prefix@ srcdir = @srcdir@ INSTALL = @INSTALL@ INSTALL_PROGRAM = @INSTALL_PROGRAM@ INSTALL_DATA = @INSTALL_DATA@ EXE = @EXE@ all: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) @XPDF_TARGET@ all-no-x: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) all-no-x xpdf: dummy cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) xpdf$(EXE) pdftops: dummy cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdftops$(EXE) pdftotext: dummy cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdftotext$(EXE) pdfinfo: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdfinfo$(EXE) pdffonts: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdffonts$(EXE) pdfdetach: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdfdetach$(EXE) pdftoppm: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdftoppm$(EXE) pdfimages: cd goo; $(MAKE) cd @UP_DIR@fofi; $(MAKE) cd @UP_DIR@splash; $(MAKE) cd @UP_DIR@xpdf; $(MAKE) pdfimages$(EXE) dummy: install: dummy -mkdir -p $(DESTDIR)@bindir@ @X@ $(INSTALL_PROGRAM) xpdf/xpdf$(EXE) $(DESTDIR)@bindir@/xpdf$(EXE) $(INSTALL_PROGRAM) xpdf/pdftops$(EXE) $(DESTDIR)@bindir@/pdftops$(EXE) $(INSTALL_PROGRAM) xpdf/pdftotext$(EXE) $(DESTDIR)@bindir@/pdftotext$(EXE) $(INSTALL_PROGRAM) xpdf/pdfinfo$(EXE) $(DESTDIR)@bindir@/pdfinfo$(EXE) $(INSTALL_PROGRAM) xpdf/pdffonts$(EXE) $(DESTDIR)@bindir@/pdffonts$(EXE) $(INSTALL_PROGRAM) xpdf/pdfdetach$(EXE) $(DESTDIR)@bindir@/pdfdetach$(EXE) @X@ $(INSTALL_PROGRAM) xpdf/pdftoppm$(EXE) $(DESTDIR)@bindir@/pdftoppm$(EXE) $(INSTALL_PROGRAM) xpdf/pdfimages$(EXE) $(DESTDIR)@bindir@/pdfimages$(EXE) -mkdir -p $(DESTDIR)@mandir@/man1 @X@ $(INSTALL_DATA) $(srcdir)/doc/xpdf.1 $(DESTDIR)@mandir@/man1/xpdf.1 $(INSTALL_DATA) $(srcdir)/doc/pdftops.1 $(DESTDIR)@mandir@/man1/pdftops.1 $(INSTALL_DATA) $(srcdir)/doc/pdftotext.1 $(DESTDIR)@mandir@/man1/pdftotext.1 $(INSTALL_DATA) $(srcdir)/doc/pdfinfo.1 $(DESTDIR)@mandir@/man1/pdfinfo.1 $(INSTALL_DATA) $(srcdir)/doc/pdffonts.1 $(DESTDIR)@mandir@/man1/pdffonts.1 $(INSTALL_DATA) $(srcdir)/doc/pdfdetach.1 $(DESTDIR)@mandir@/man1/pdfdetach.1 @X@ $(INSTALL_DATA) $(srcdir)/doc/pdftoppm.1 $(DESTDIR)@mandir@/man1/pdftoppm.1 $(INSTALL_DATA) $(srcdir)/doc/pdfimages.1 $(DESTDIR)@mandir@/man1/pdfimages.1 -mkdir -p $(DESTDIR)@mandir@/man5 $(INSTALL_DATA) $(srcdir)/doc/xpdfrc.5 $(DESTDIR)@mandir@/man5/xpdfrc.5 -mkdir -p $(DESTDIR)@sysconfdir@ @if test ! -f $(DESTDIR)@sysconfdir@/xpdfrc; then \ echo "$(INSTALL_DATA) $(srcdir)/doc/sample-xpdfrc $(DESTDIR)@sysconfdir@/xpdfrc"; \ $(INSTALL_DATA) $(srcdir)/doc/sample-xpdfrc $(DESTDIR)@sysconfdir@/xpdfrc; \ else \ echo "# not overwriting the existing $(DESTDIR)@sysconfdir@/xpdfrc"; \ fi clean: -cd goo; $(MAKE) clean -cd @UP_DIR@fofi; $(MAKE) clean -cd @UP_DIR@splash; $(MAKE) clean -cd @UP_DIR@xpdf; $(MAKE) clean distclean: clean rm -f config.log config.status config.cache rm -f aconf.h rm -f Makefile goo/Makefile xpdf/Makefile rm -f goo/Makefile.dep fofi/Makefile.dep splash/Makefile.dep xpdf/Makefile.dep rm -f goo/Makefile.in.bak fofi/Makefile.in.bak splash/Makefile.in.bak xpdf/Makefile.in.bak touch goo/Makefile.dep touch fofi/Makefile.dep touch splash/Makefile.dep touch xpdf/Makefile.dep depend: cd goo; $(MAKE) depend cd @UP_DIR@fofi; $(MAKE) depend cd @UP_DIR@splash; $(MAKE) depend cd @UP_DIR@xpdf; $(MAKE) depend xpdf-3.03/README0000644000076400007640000003544411622305345012605 0ustar derekndereknXpdf ==== version 3.03 2011-aug-15 The Xpdf software and documentation are copyright 1996-2011 Glyph & Cog, LLC. Email: derekn@foolabs.com WWW: http://www.foolabs.com/xpdf/ The PDF data structures, operators, and specification are copyright 1985-2006 Adobe Systems Inc. What is Xpdf? ------------- Xpdf is an open source viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Windows and Mac OSX systems and should run on pretty much any system with a decent C++ compiler. Xpdf will run on 32-bit and 64-bit machines. License & Distribution ---------------------- Xpdf is licensed under the GNU General Pulbic License (GPL), version 2 or 3. This means that you can distribute derivatives of Xpdf under any of the following: - GPL v2 only - GPL v3 only - GPL v2 or v3 The Xpdf source package includes the text of both GPL versions: COPYING for GPL v2, COPYING3 for GPL v3. Please note that Xpdf is NOT licensed under "any later version" of the GPL, as I have no idea what those versions will look like. If you are redistributing unmodified copies of Xpdf (or any of the Xpdf tools) in binary form, you need to include all of the documentation: README, man pages (or help files), COPYING, and COPYING3. If you want to incorporate the Xpdf source code into another program (or create a modified version of Xpdf), and you are distributing that program, you have two options: release your program under the GPL (v2 and/or v3), or purchase a commercial Xpdf source license. If you're interested in commercial licensing, please see the Glyph & Cog web site: http://www.glyphandcog.com/ Compatibility ------------- Xpdf is developed and tested on Linux. In addition, it has been compiled by others on Solaris, AIX, HP-UX, Digital Unix, Irix, and numerous other Unix implementations, as well as VMS and OS/2. It should work on pretty much any system which runs X11 and has Unix-like libraries. You'll need ANSI C++ and C compilers to compile it. The non-X components of Xpdf (pdftops, pdftotext, pdfinfo, pdffonts, pdfdetach, pdftoppm, and pdfimages) can also be compiled on Windows and Mac OSX systems. See the Xpdf web page for details. If you compile Xpdf for a system not listed on the web page, please let me know. If you're willing to make your binary available by ftp or on the web, I'll be happy to add a link from the Xpdf web page. I have decided not to host any binaries I didn't compile myself (for disk space and support reasons). If you can't get Xpdf to compile on your system, send me email and I'll try to help. Xpdf has been ported to the Acorn, Amiga, BeOS, and EPOC. See the Xpdf web page for links. Getting Xpdf ------------ The latest version is available from: http://www.foolabs.com/xpdf/ or: ftp://ftp.foolabs.com/pub/xpdf/ Source code and several precompiled executables are available. Announcements of new versions are posted to comp.text.pdf and emailed to a list of people. If you'd like to receive email notification of new versions, just let me know. Running Xpdf ------------ To run xpdf, simply type: xpdf file.pdf To generate a PostScript file, hit the "print" button in xpdf, or run pdftops: pdftops file.pdf To generate a plain text file, run pdftotext: pdftotext file.pdf There are five additional utilities (which are fully described in their man pages): pdfinfo -- dumps a PDF file's Info dictionary (plus some other useful information) pdffonts -- lists the fonts used in a PDF file along with various information for each font pdfdetach -- lists or extracts embedded files (attachments) from a PDF file pdftoppm -- converts a PDF file to a series of PPM/PGM/PBM-format bitmaps pdfimages -- extracts the images from a PDF file Command line options and many other details are described in the man pages (xpdf(1), etc.) and the VMS help files (xpdf.hlp, etc.). All of these utilities read an optional configuration file: see the xpdfrc(5) man page. Upgrading from Xpdf 3.02 (and earlier) -------------------------------------- The font configuration system has been changed. Previous versions used mostly separate commands to configure fonts for display and for PostScript output. As of 3.03, configuration options that make sense for both display and PS output have been unified. The following xpdfrc commands have been removed: * displayFontT1, displayFontTT: replaced with fontFile * displayNamedCIDFontT1, displayNamedCIDFontTT: replaced with fontFile * displayCIDFontT1, displayCIDFontTT: replaced with fontFileCC * psFont: replaced with psResidentFont * psNamedFont16: replaced with psResidentFont16 * psFont16: replaced with psResidentFontCC See the xpdfrc(5) man page for more information on the new commands. Pdftops will now embed external 16-bit fonts (configured with the fontFileCC command) when the PDF file refers to a non-embedded font. It does not do any subsetting (yet), so the resulting PS files will be large. Compiling Xpdf -------------- See the separate file, INSTALL. Bugs ---- If you find a bug in Xpdf, i.e., if it prints an error message, crashes, or incorrectly displays a document, and you don't see that bug listed here, please send me email, with a pointer (URL, ftp site, etc.) to the PDF file.

Generated automatically by mantohlp 1 pdftotext pdftotext - Portable Document Format (PDF) to text converter pdftotext [options] [PDF-file [text-file]] Pdftotext converts Portable Document Format (PDF) files to plain text. Pdftotext reads the PDF file, PDF-file, and writes a text file, text- file. If text-file is not specified, pdftotext converts file.pdf to file.txt. If text-file is '-', the text is sent to stdout. () 2 ONFIGURATION_FIL Pdftotext reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftotext is built). See the xpdfrc(5) man page for details. () 2 OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to convert. -l number Specifies the last page to convert. -layout Maintain (as best as possible) the original physical layout of the text. The default is to 'undo' physical layout (columns, hyphenation, etc.) and output the text in reading order. -fixed number Assume fixed-pitch (or tabular) text, with the specified charac- ter width (in points). This forces physical layout mode. -raw Keep the text in content stream order. This is a hack which often "undoes" column formatting, etc. Use of raw mode is no longer recommended. -htmlmeta Generate a simple HTML file, including the meta information. This simply wraps the text in 
 and
and prepends the meta headers. -enc encoding-name Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). The encoding name is case-sensitive. This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding] -eol unix | dos | mac Sets the end-of-line convention to use for text output. [config file: textEOL] -nopgbrk Don't insert page breaks (form feed characters) between pages. [config file: textPageBreaks] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) () 2 BUGS Some PDF files contain fonts whose encodings have been mangled beyond recognition. There is no way (short of OCR) to extract text from these files. () 2 XIT_CODE The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error.

(These are also sometimes also called \'Acrobat' files, from the name of Adobe's PDF software.) Xpdf runs under the X Window System on UNIX, VMS, and OS/2. .PP To run xpdf, simply type: .PP .RS xpdf file.pdf .RE .PP where .I file.pdf is your PDF file. The file name can be followed by a number specifying the page which should be displayed first, e.g.: .PP .RS xpdf file.pdf 18 .RE .PP You can also give a named destination, prefixed with \'+' in place of the page number. (This is only useful with PDF files that provide named destination targets.) .PP You can also start xpdf without opening any files: .PP .RS xpdf .RE .SH CONFIGURATION FILE Xpdf reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when xpdf is built). See the .BR xpdfrc (5) man page for details. .SH OPTIONS Many of the following options can be set with configuration file commands or X resources. These are listed in square brackets with the description of the corresponding command line option. .TP .BI \-g " geometry" Set the initial window geometry. .RB ( \-geometry is equivalent.) .RB "[X resource: " xpdf.geometry ] .TP .BI \-title " title" Set the window title. By default, the title will be "xpdf: foo.pdf". .RB "[X resource: " xpdf.title ] .TP .B \-cmap Install a private colormap. This is ignored on TrueColor visuals. .RB "[X resource: " xpdf.installCmap ] .TP .BI \-rgb " number" Set the size of largest RGB cube xpdf will try to allocate. The default is 5 (for a 5x5x5 cube); set to a smaller number to conserve color table entries. This is ignored with private colormaps and on TrueColor visuals. .RB "[X resource: " xpdf.rgbCubeSize ] .TP .B \-rv Set reverse video mode. This reverses the colors of everything except images. It may not always produce great results for PDF files which do weird things with color. This also causes the paper color to default to black. .RB "[X resource: " xpdf.reverseVideo ] .TP .BI \-papercolor " color" Set the "paper color", i.e., the background of the page display. This will not work too well with PDF files that do things like filling in white behind the text. .RB "[X resource: " xpdf.paperColor ] .TP .BI \-mattecolor " color" Set the matte color, i.e., the color used for background outside the actual page area. (There is a separate setting, xpdf.fullScreenMatteColor, for full-screen mode.) .RB "[X resource: " xpdf.matteColor ] .TP .BI \-z " zoom" Set the initial zoom factor. A number specifies a zoom percentage, where 100 means 72 dpi. You may also specify \'page', to fit the page to the window size, or \'width', to fit the page width to the window width. .RB "[config file: " initialZoom "; or X resource: " xpdf.initialZoom ] .TP .B \-cont Start in continuous view mode, i.e., with one vertical scroll bar for the whole document. .RB "[config file: " continuousView ] .TP .BI \-t1lib " yes | no" Enable or disable t1lib (a Type 1 font rasterizer). This defaults to "yes". .RB "[config file: " enableT1lib ] .TP .BI \-freetype " yes | no" Enable or disable FreeType (a TrueType / Type 1 font rasterizer). This defaults to "yes". .RB "[config file: " enableFreeType ] .TP .BI \-aa " yes | no" Enable or disable font anti-aliasing. This defaults to "yes". .RB "[config file: " antialias ] .TP .BI \-aaVector " yes | no" Enable or disable vector anti-aliasing. This defaults to "yes". .RB "[config file: " vectorAntialias ] .TP .BI \-ps " PS-file" Set the default file name for PostScript output (i.e., the name which will appear in the print dialog). This can also be of the form \'|command' to pipe the PostScript through a command. .RB "[config file: " psFile ] .TP .BI \-paper " size" Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. .RB "[config file: " psPaperSize ] .TP .BI \-paperw " size" Set the paper width, in points. .RB "[config file: " psPaperSize ] .TP .BI \-paperh " size" Set the paper height, in points. .RB "[config file: " psPaperSize ] .TP .B \-level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. .RB "[config file: " psLevel ] .TP .BI \-enc " encoding-name" Sets the encoding to use for text output. The .I encoding\-name must be defined with the unicodeMap command (see .BR xpdfrc (5)). This defaults to "Latin1" (which is a built-in encoding). .RB "[config file: " textEncoding ] .TP .BI \-eol " unix | dos | mac" Sets the end-of-line convention to use for text output. .RB "[config file: " textEOL ] .TP .BI \-opw " password" Specify the owner password for the PDF file. Providing this will bypass all security restrictions. .TP .BI \-upw " password" Specify the user password for the PDF file. .TP .B \-fullscreen Open xpdf in full-screen mode, useful for presentations. .TP .BI \-remote " name" Start/contact xpdf remote server with specified name (see the .B "REMOTE SERVER MODE" section below). .TP .BI \-exec " command" Execute a command (see the .B COMMANDS section below) in an xpdf remote server window (with \-remote only). .TP .B \-reload Reload xpdf remote server window (with \-remote only). .TP .B \-raise Raise xpdf remote server window (with \-remote only). .TP .B \-quit Kill xpdf remote server (with \-remote only). .TP .B \-cmd Print commands as they're executed (useful for debugging). .RB "[config file: " printCommands ] .TP .B \-q Don't print any messages or errors. .RB "[config file: " errQuiet ] .TP .BI \-cfg " config-file" Read .I config-file in place of ~/.xpdfrc or the system-wide config file. .TP .B \-v Print copyright and version information. .TP .B \-h Print usage information. .RB ( \-help and .B \-\-help are equivalent.) .PP Several other standard X options and resources will work as expected: .TP .BI \-display " display" .RB "[X resource: " xpdf.display ] .TP .BI \-fg " color" .RB ( \-foreground is equivalent.) .RB "[X resource: " xpdf*Foreground ] .TP .BI \-bg " color" .RB ( \-background is equivalent.) .RB "[X resource: " xpdf*Background ] .TP .BI \-font " font" .RB ( \-fn is equivalent.) .RB "[X resource: " xpdf*fontList ] .PP The color and font options only affect the user interface elements, not the PDF display (the \'paper'). .PP The following X resources do not have command line option equivalents: .TP .B xpdf.toolTipEnable Enables (if set to true) or disables (if set to false) the tool-tips on the toolbar buttons. .TP .B xpdf.fullScreenMatteColor Sets the matte color to be used in full-screen mode. The default setting is "black". .SH CONTROLS .SS On-screen controls, at the bottom of the xpdf window .TP .B "left/right arrow buttons" Move to the previous/next page. .TP .B "double left/right arrow buttons" Move backward or forward by ten pages. .TP .B "dashed left/right arrow buttons" Move backward or forward along the history path. .TP .B "\'Page' entry box" Move to a specific page number. Click in the box to activate it, type the page number, then hit return. .TP .B "zoom popup menu" Change the zoom factor (see the description of the \-z option above). .TP .B "binoculars button" Find a text string. .TP .B "print button" Bring up a dialog for generating a PostScript file. The dialog has options to set the pages to be printed and the PostScript file name. The file name can be \'-' for stdout or \'|command' to pipe the PostScript through a command, e.g., \'|lpr'. .TP .B "\'?' button" Bring up the \'about xpdf' window. .TP .B "link info" The space between the \'?' and \'Quit' buttons is used to show the URL or external file name when the mouse is over a link. .TP .B "\'Quit' button" Quit xpdf. .PP .SS Menu Pressing the right mouse button will post a popup menu with the following commands: .TP .B "Open..." Open a new PDF file via a file requester. .TP .B "Open in new window..." Create a new window and open a new PDF file via a file requester. .TP .B "Reload" Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. .TP .B "Save as..." Save the current file via a file requester. .TP .B "Continuous view" Toggles between single page and continuous view modes. .TP .B "Rotate counterclockwise" Rotate the page 90 degrees counterclockwise. .TP .B "Rotate clockwise" Rotate the page 90 degrees clockwise. The two rotate commands are intended primarily for PDF files where the rotation isn't correctly specified in the file. .TP .B "Zoom to selection" Zoom in to the currently selected rectangle. .TP .B "Close" Close the current window. If this is the only open window, the document is closed, but the window is left open (i.e., this menu command won't quit xpdf). .TP .B "Quit" Quit xpdf. .PP .SS Outline If the PDF contains an outline (a.k.a., bookmarks), there will be an outline pane on the left side of the window. The width of the outline pane is adjustable with a vertical split bar via the knob near its bottom end. .PP .SS Text selection Dragging the mouse with the left button held down will highlight an arbitrary rectangle. Any text inside this rectangle will be copied to the X selection buffer. .PP .SS Links Clicking on a hyperlink will jump to the link's destination. A link to another PDF document will make xpdf load that document. A \'launch' link to an executable program will display a dialog, and if you click \'ok', execute the program. URL links call an external command (see the .B WEB BROWSERS section below). .PP .SS Panning Dragging the mouse with the middle button held down pans the window. .PP .SS Key bindings .TP .B o Open a new PDF file via a file requester. .TP .B r Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. .TP .B control-L Redraw the current page. .TP .B control-W Close the current window. .TP .B f or control-F Find a text string. .TP .B control-G Find next occurrence. .TP .B control-P Print. .TP .B n Move to the next page. Scrolls to the top of the page, unless scroll lock is turned on. .TP .B p Move to the previous page. Scrolls to the top of the page, unless scroll lock is turned on. .TP .BR " or " " or " Scroll down on the current page; if already at bottom, move to next page. .TP .BR " or " " or " " or " Scroll up on the current page; if already at top, move to previous page. .TP .B v Move forward along the history path. .TP .B b Move backward along the history path. .TP .B Scroll to top of current page. .TP .B Scroll to bottom of current page. .TP .B control- Scroll to first page of document. .TP .B control- Scroll to last page of document. .TP .B arrows Scroll the current page. .TP .B g Activate the page number text field ("goto page"). .TP .B 0 Set the zoom factor to 125%. .TP .B + Zoom in (increment the zoom factor by 1). .TP .B - Zoom out (decrement the zoom factor by 1). .TP .B z Set the zoom factor to 'page' (fit page to window). .TP .B w Set the zoom factor to 'width' (fit page width to window). .TP .B alt-F Toggle full-screen mode. .TP .B q Quit xpdf. .SH "WEB BROWSERS" If you want to run xpdf automatically from netscape or mosaic (and probably other browsers) when you click on a link to a PDF file, you need to edit (or create) the files .I .mime.types and .I .mailcap in your home directory. In .I .mime.types add the line: .PP .RS application/pdf pdf .RE .PP In .I .mailcap add the lines: .PP .RS # Use xpdf to view PDF files. .RE .RS application/pdf; xpdf \-q %s .RE .PP Make sure that xpdf is on your executable search path. .PP When you click on a URL link in a PDF file, xpdf will execute the command specified by the urlCommand config file option, replacing an occurrence of \'%s' with the URL. For example, to call netscape with the URL, add this line to your config file: .PP .RS urlCommand "netscape \-remote 'openURL(%s)'" .RE .SH COMMANDS Xpdf's key and mouse bindings are user-configurable, using the bind and unbind options in the config file (see .BR xpdfrc (5)). The bind command allows you to bind a key or mouse button to a sequence of one or more commands. .SS Available Commands The following commands are supported: .TP .BI gotoPage( page ) Go to the specified page. .TP .BI gotoPageNoScroll( page ) Go to the specified page, with the current relative scroll position. .TP .BI gotoDest( dest ) Go to a named destination. .TP .B gotoLastPage Go to the last page in the PDF file. .TP .B gotoLastPageNoScroll Go to the last page in the PDF file, with the current relative scroll position. .TP .B nextPage Go to the next page. .TP .B nextPageNoScroll Go to the next page, with the current relative scroll position. .TP .B prevPage Go to the previous page. .TP .B prevPageNoScroll Go to the previous page, with the current relative scroll position. .TP .B pageUp Scroll up by one screenful. .TP .B pageDown Scroll down by one screenful. .TP .BI scrollLeft( n ) Scroll left by .I n pixels. .TP .BI scrollRight( n ) Scroll right by .I n pixels. .TP .BI scrollUp( n ) Scroll up by .I n pixels. .TP .BI scrollDown( n ) Scroll down by .I n pixels. .TP .BI scrollUpPrevPage( n ) Scroll up by .I n pixels, moving to the previous page if appropriate. .TP .BI scrollDownPrevPage( n ) Scroll down by .I n pixels, moving to the next page if appropriate. .TP .B scrollToTopEdge Scroll to the top edge of the current page, with no horizontal movement. .TP .B scrollToBottomEdge Scroll to the bottom edge of the current page, with no horizontal movement. .TP .B scrollToLeftEdge Scroll to the left edge of the current page, with no vertical movement. .TP .B scrollToRightEdge Scroll to the right edge of the current page, with no vertical movement. .TP .B scrollToTopLeft Scroll to the top-left corner of the current page. .TP .B scrollToBottomRight Scroll to the bottom-right corner of the current page. .TP .B goForward Move forward along the history path. .TP .B goBackward Move backward along the history path. .TP .BI zoomPercent( z ) Set the zoom factor to .IR z %. .TP .B zoomFitPage Set the zoom factor to fit-page. .TP .B zoomFitWidth Set the zoom factor to fit-width. .TP .B zoomIn Zoom in - go to the next higher zoom factor. .TP .B zoomOut Zoom out - go the next lower zoom factor. .TP .B rotateCW Rotate the page 90 degrees clockwise. .TP .B rotateCCW Rotate the page 90 degrees counterclockwise. .TP .BI setSelection( pg , ulx , uly , lrx , lry ) Set the selection to the specified coordinates on the specified page. .TP .B continuousMode Go to continuous view mode. .TP .B singlePageMode Go to single-page view mode. .TP .B toggleContinuousMode Toggle between continuous and single page view modes. .TP .B fullScreenMode Go to full-screen mode. .TP .B windowMode Go to window (non-full-screen) mode. .TP .B toggleFullScreenMode Toggle between full-screen and window modes. .TP .B open Open a PDF file in this window, using the open dialog. .TP .B openInNewWin Open a PDF file in a new window, using the open dialog. .TP .BI openFile( file ) Open a specified PDF file in this window. .TP .BI openFileInNewWin( file ) Open a specified PDF file in a new window. .TP .BI openFileAtDest( file , dest ) Open a specified PDF file in this window and go to a named destination. .TP .BI openFileAtDestInNewWin( file , dest ) Open a specified PDF file in a new window and go to a named destination. .TP .B reload Reload the current PDF file. .TP .B redraw Redraw the window. .TP .B raise Raise the window to the front. .TP .B closeWindow Close the window. .TP .BI run( external-command-string ) Run an external command.

It is no longer available, but the following bindings are equivalent: .nf bind h any scrollLeft(16) bind l any scrollRight(16) bind k any scrollUp(16) bind j any scrollDown(16) .fi .SH "REMOTE SERVER MODE" Xpdf can be started in remote server mode by specifying a server name (in addition to the file name and page number). For example: .PP .RS xpdf \-remote myServer file.pdf .RE .PP If there is currently no xpdf running in server mode with the name \'myServer', a new xpdf window will be opened. If another command: .PP .RS xpdf \-remote myServer another.pdf 9 .RE .PP is issued, a new copy of xpdf will not be started. Instead, the first xpdf (the server) will load .I another.pdf and display page nine. If the file name is the same: .PP .RS xpdf \-remote myServer another.pdf 4 .RE .PP the xpdf server will simply display the specified page. .PP The \-raise option tells the server to raise its window; it can be specified with or without a file name and page number. .PP The \-quit option tells the server to close its window and exit. .SH EXIT CODES The Xpdf tools use the following exit codes: .TP 0 No error. .TP 1 Error opening a PDF file. .TP 2 Error opening an output file. .TP 3 Error related to PDF permissions. .TP 99 Other error. .SH AUTHOR The xpdf software and documentation are copyright 1996-2011 Glyph & Cog, LLC. .SH "SEE ALSO" .BR pdftops (1), .BR pdftotext (1), .BR pdfinfo (1), .BR pdffonts (1), .BR pdfdetach (1), .BR pdftoppm (1), .BR pdfimages (1), .BR xpdfrc (5) .br .B http://www.foolabs.com/xpdf/ xpdf-3.03/doc/pdfdetach.10000644000076400007640000000537311622305345014474 0ustar dereknderekn.\" Copyright 2011 Glyph & Cog, LLC .TH pdfdetach 1 "15 August 2011" .SH NAME pdfdetach \- Portable Document Format (PDF) document embedded file extractor (version 3.03) .SH SYNOPSIS .B pdfdetach [options] .RI [ PDF-file ] .SH DESCRIPTION .B Pdfdetach lists or extracts embedded files (attachments) from a Portable Document Format (PDF) file. .SH CONFIGURATION FILE Pdfdetach reads a configuration file at startup.

Pdftops reads the PDF file, PDF-file, and writes a PostScript file, PS- file. If PS-file is not specified, pdftops converts file.pdf to file.ps (or file.eps with the -eps option). If PS-file is '-', the PostScript is sent to stdout. CONFIGURATION FILE Pdftops reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftops is built). See the xpdfrc(5) man page for details. OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to print. -l number Specifies the last page to print. -level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. No more than one of the PostScript level options (-level1, -level1sep, -level2, -level2sep, -level3, -level3Sep) may be given. [config file: psLevel] -level1sep Generate Level 1 separable PostScript. All colors are converted to CMYK. Images are written with separate stream data for the four components. [config file: psLevel] -level2 Generate Level 2 PostScript. Level 2 supports color images and image compression. This is the default setting. [config file: psLevel] -level2sep Generate Level 2 separable PostScript. All colors are converted to CMYK. The PostScript separation convention operators are used to handle custom (spot) colors. [config file: psLevel] -level3 Generate Level 3 PostScript. This enables all Level 2 features plus CID font embedding and masked image generation. [config file: psLevel] -level3Sep Generate Level 3 separable PostScript. The separation handling is the same as for -level2Sep. [config file: psLevel] -eps Generate an Encapsulated PostScript (EPS) file. An EPS file contains a single image, so if you use this option with a multi- page PDF file, you must use -f and -l to specify a single page. No more than one of the mode options (-eps, -form) may be given. -form Generate a PostScript form which can be imported by software that understands forms. A form contains a single page, so if you use this option with a multi-page PDF file, you must use -f and -l to specify a single page. The -level1 option cannot be used with -form. -opi Generate OPI comments for all images and forms which have OPI information. (This option is only available if pdftops was com- piled with OPI support.) [config file: psOPI] -noembt1 By default, any Type 1 fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make Post- Script files larger, but may be necessary for readable output. [config file: psEmbedType1Fonts] -noembtt By default, any TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make PostScript files larger, but may be necessary for readable out- put. Also, some PostScript interpreters do not have TrueType rasterizers. [config file: psEmbedTrueTypeFonts] -noembcidps By default, any CID PostScript fonts which are embedded in the PDF file are copied into the PostScript file. This option dis- ables that embedding. No attempt is made to substitute for non- embedded CID PostScript fonts. [config file: psEmbedCID- PostScriptFonts] -noembcidtt By default, any CID TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option disables that embedding. No attempt is made to substitute for non-embed- ded CID TrueType fonts. [config file: psEmbedCIDTrueTypeFonts] -preload Convert PDF forms to PS procedures, and preload image data. This uses more memory in the PostScript interpreter, but gener- ates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. -paper size Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. [config file: psPaperSize] -paperw size Set the paper width, in points. [config file: psPaperSize] -paperh size Set the paper height, in points. [config file: psPaperSize] -nocrop By default, output is cropped to the CropBox specified in the PDF file. This option disables cropping. [config file: psCrop] -expand Expand PDF pages smaller than the paper to fill the paper. By default, these pages are not scaled. [config file: psExpandS- maller] -noshrink Don't scale PDF pages which are larger than the paper. By default, pages larger than the paper are shrunk to fit. [config file: psShrinkLarger] -nocenter By default, PDF pages smaller than the paper (after any scaling) are centered on the paper. This option causes them to be aligned to the lower-left corner of the paper instead. [config file: psCenter] -pagecrop Treat the CropBox as the PDF page size. By default, the Media- Box is used as the page size. -duplex Set the Duplex pagedevice entry in the PostScript file. This tells duplex-capable printers to enable duplexing. [config file: psDuplex] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) EXIT CODES The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error.

Generated automatically by mantohlp 1 xpdf xpdf - Portable Document Format (PDF) file viewer for X (version 3.03) xpdf [options] [PDF-file [page | +dest]] Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) Xpdf runs under the X Window System on UNIX, VMS, and OS/2. To run xpdf, simply type: xpdf file.pdf where file.pdf is your PDF file. The file name can be followed by a number specifying the page which should be displayed first, e.g.: xpdf file.pdf 18 You can also give a named destination, prefixed with '+' in place of the page number. (This is only useful with PDF files that provide named destination targets.) You can also start xpdf without opening any files: xpdf () 2 ONFIGURATION_FIL Xpdf reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when xpdf is built). See the xpdfrc(5) man page for details. () 2 OPTIONS Many of the following options can be set with configuration file com- mands or X resources. These are listed in square brackets with the description of the corresponding command line option. -g geometry Set the initial window geometry. (-geometry is equivalent.) [X resource: xpdf.geometry] -title title Set the window title. By default, the title will be "xpdf: foo.pdf". [X resource: xpdf.title] -cmap Install a private colormap. This is ignored on TrueColor visu- als. [X resource: xpdf.installCmap] -rgb number Set the size of largest RGB cube xpdf will try to allocate. The default is 5 (for a 5x5x5 cube); set to a smaller number to con- serve color table entries. This is ignored with private col- ormaps and on TrueColor visuals. [X resource: xpdf.rgbCubeSize] -rv Set reverse video mode. This reverses the colors of everything except images. It may not always produce great results for PDF files which do weird things with color. This also causes the paper color to default to black. [X resource: xpdf.reverseV- ideo] -papercolor color Set the "paper color", i.e., the background of the page display. This will not work too well with PDF files that do things like filling in white behind the text. [X resource: xpdf.paperColor] -mattecolor color Set the matte color, i.e., the color used for background outside the actual page area. (There is a separate setting, xpdf.fullScreenMatteColor, for full-screen mode.) [X resource: xpdf.matteColor] -z zoom Set the initial zoom factor. A number specifies a zoom percent- age, where 100 means 72 dpi. You may also specify 'page', to fit the page to the window size, or 'width', to fit the page width to the window width. [config file: initialZoom; or X resource: xpdf.initialZoom] -cont Start in continuous view mode, i.e., with one vertical scroll bar for the whole document. [config file: continuousView] -t1lib yes | no Enable or disable t1lib (a Type 1 font rasterizer). This defaults to "yes". [config file: enableT1lib] -freetype yes | no Enable or disable FreeType (a TrueType / Type 1 font raster- izer). This defaults to "yes". [config file: enableFreeType] -aa yes | no Enable or disable font anti-aliasing. This defaults to "yes". [config file: antialias] -aaVector yes | no Enable or disable vector anti-aliasing. This defaults to "yes". [config file: vectorAntialias] -ps PS-file Set the default file name for PostScript output (i.e., the name which will appear in the print dialog). This can also be of the form '|command' to pipe the PostScript through a command. [con- fig file: psFile] -paper size Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. [config file: psPaperSize] -paperw size Set the paper width, in points. [config file: psPaperSize] -paperh size Set the paper height, in points. [config file: psPaperSize] -level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. [config file: psLevel] -enc encoding-name Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [con- fig file: textEncoding] -eol unix | dos | mac Sets the end-of-line convention to use for text output. [config file: textEOL] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -fullscreen Open xpdf in full-screen mode, useful for presentations. -remote name Start/contact xpdf remote server with specified name (see the REMOTE SERVER MODE section below). -exec command Execute a command (see the COMMANDS section below) in an xpdf remote server window (with -remote only). -reload Reload xpdf remote server window (with -remote only). -raise Raise xpdf remote server window (with -remote only). -quit Kill xpdf remote server (with -remote only). -cmd Print commands as they're executed (useful for debugging). [config file: printCommands] -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) Several other standard X options and resources will work as expected: -display display [X resource: xpdf.display] -fg color (-foreground is equivalent.) [X resource: xpdf*Foreground] -bg color (-background is equivalent.) [X resource: xpdf*Background] -font font (-fn is equivalent.) [X resource: xpdf*fontList] The color and font options only affect the user interface elements, not the PDF display (the 'paper'). The following X resources do not have command line option equivalents: xpdf.toolTipEnable Enables (if set to true) or disables (if set to false) the tool- tips on the toolbar buttons. xpdf.fullScreenMatteColor Sets the matte color to be used in full-screen mode. The default setting is "black". () 2 CONTROLS On-screen controls, at the bottom of the xpdf window left/right arrow buttons Move to the previous/next page. double left/right arrow buttons Move backward or forward by ten pages. dashed left/right arrow buttons Move backward or forward along the history path. 'Page' entry box Move to a specific page number. Click in the box to activate it, type the page number, then hit return. zoom popup menu Change the zoom factor (see the description of the -z option above). binoculars button Find a text string. print button Bring up a dialog for generating a PostScript file. The dialog has options to set the pages to be printed and the PostScript file name. The file name can be '-' for stdout or '|command' to pipe the PostScript through a command, e.g., '|lpr'. '?' button Bring up the 'about xpdf' window. link info The space between the '?' and 'Quit' buttons is used to show the URL or external file name when the mouse is over a link. 'Quit' button Quit xpdf. Menu Pressing the right mouse button will post a popup menu with the follow- ing commands: Open... Open a new PDF file via a file requester. Open in new window... Create a new window and open a new PDF file via a file requester. Reload Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. Save as... Save the current file via a file requester. Continuous view Toggles between single page and continuous view modes. Rotate counterclockwise Rotate the page 90 degrees counterclockwise. Rotate clockwise Rotate the page 90 degrees clockwise. The two rotate commands are intended primarily for PDF files where the rotation isn't correctly specified in the file. Zoom to selection Zoom in to the currently selected rectangle. Close Close the current window. If this is the only open window, the document is closed, but the window is left open (i.e., this menu command won't quit xpdf). Quit Quit xpdf. Outline If the PDF contains an outline (a.k.a., bookmarks), there will be an outline pane on the left side of the window. The width of the outline pane is adjustable with a vertical split bar via the knob near its bot- tom end. Text selection Dragging the mouse with the left button held down will highlight an arbitrary rectangle. Any text inside this rectangle will be copied to the X selection buffer. Links Clicking on a hyperlink will jump to the link's destination. A link to another PDF document will make xpdf load that document. A 'launch' link to an executable program will display a dialog, and if you click 'ok', execute the program. URL links call an external command (see the WEB BROWSERS section below). Panning Dragging the mouse with the middle button held down pans the window. Key bindings o Open a new PDF file via a file requester. r Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. control-L Redraw the current page. control-W Close the current window. f or control-F Find a text string. control-G Find next occurrence. control-P Print. n Move to the next page. Scrolls to the top of the page, unless scroll lock is turned on. p Move to the previous page. Scrolls to the top of the page, unless scroll lock is turned on. or or Scroll down on the current page; if already at bottom, move to next page. or or or Scroll up on the current page; if already at top, move to previ- ous page. v Move forward along the history path. b Move backward along the history path. Scroll to top of current page. Scroll to bottom of current page. control- Scroll to first page of document. control- Scroll to last page of document. arrows Scroll the current page. g Activate the page number text field ("goto page"). 0 Set the zoom factor to 125%. + Zoom in (increment the zoom factor by 1). - Zoom out (decrement the zoom factor by 1). z Set the zoom factor to 'page' (fit page to window). w Set the zoom factor to 'width' (fit page width to window). alt-F Toggle full-screen mode. q Quit xpdf. () 2 WEB_BROWSERS If you want to run xpdf automatically from netscape or mosaic (and probably other browsers) when you click on a link to a PDF file, you need to edit (or create) the files .mime.types and .mailcap in your home directory. In .mime.types add the line: application/pdf pdf In .mailcap add the lines: # Use xpdf to view PDF files. application/pdf; xpdf -q %s Make sure that xpdf is on your executable search path. When you click on a URL link in a PDF file, xpdf will execute the com- mand specified by the urlCommand config file option, replacing an occurrence of '%s' with the URL. For example, to call netscape with the URL, add this line to your config file: urlCommand "netscape -remote 'openURL(%s)'" () 2 COMMANDS Xpdf's key and mouse bindings are user-configurable, using the bind and unbind options in the config file (see xpdfrc(5)). The bind command allows you to bind a key or mouse button to a sequence of one or more commands. Available Commands The following commands are supported: gotoPage(page) Go to the specified page. gotoPageNoScroll(page) Go to the specified page, with the current relative scroll posi- tion. gotoDest(dest) Go to a named destination. gotoLastPage Go to the last page in the PDF file. gotoLastPageNoScroll Go to the last page in the PDF file, with the current relative scroll position. nextPage Go to the next page. nextPageNoScroll Go to the next page, with the current relative scroll position. prevPage Go to the previous page. prevPageNoScroll Go to the previous page, with the current relative scroll posi- tion. pageUp Scroll up by one screenful. pageDown Scroll down by one screenful. scrollLeft(n) Scroll left by n pixels. scrollRight(n) Scroll right by n pixels. scrollUp(n) Scroll up by n pixels. scrollDown(n) Scroll down by n pixels. scrollUpPrevPage(n) Scroll up by n pixels, moving to the previous page if appropri- ate. scrollDownPrevPage(n) Scroll down by n pixels, moving to the next page if appropriate. scrollToTopEdge Scroll to the top edge of the current page, with no horizontal movement. scrollToBottomEdge Scroll to the bottom edge of the current page, with no horizon- tal movement. scrollToLeftEdge Scroll to the left edge of the current page, with no vertical movement. scrollToRightEdge Scroll to the right edge of the current page, with no vertical movement. scrollToTopLeft Scroll to the top-left corner of the current page. scrollToBottomRight Scroll to the bottom-right corner of the current page. goForward Move forward along the history path. goBackward Move backward along the history path. zoomPercent(z) Set the zoom factor to z%. zoomFitPage Set the zoom factor to fit-page. zoomFitWidth Set the zoom factor to fit-width. zoomIn Zoom in - go to the next higher zoom factor. zoomOut Zoom out - go the next lower zoom factor. rotateCW Rotate the page 90 degrees clockwise. rotateCCW Rotate the page 90 degrees counterclockwise. setSelection(pg,ulx,uly,lrx,lry) Set the selection to the specified coordinates on the specified page. continuousMode Go to continuous view mode. singlePageMode Go to single-page view mode. toggleContinuousMode Toggle between continuous and single page view modes. fullScreenMode Go to full-screen mode. windowMode Go to window (non-full-screen) mode. toggleFullScreenMode Toggle between full-screen and window modes. open Open a PDF file in this window, using the open dialog. openInNewWin Open a PDF file in a new window, using the open dialog. openFile(file) Open a specified PDF file in this window. openFileInNewWin(file) Open a specified PDF file in a new window. openFileAtDest(file,dest) Open a specified PDF file in this window and go to a named des- tination. openFileAtDestInNewWin(file,dest) Open a specified PDF file in a new window and go to a named des- tination. reload Reload the current PDF file. redraw Redraw the window. raise Raise the window to the front. closeWindow Close the window. run(external-command-string) Run an external command. The following escapes are allowed in the command string: %f => PDF file name (or an empty string if no file is open) %b => PDF file base name, i.e., file name minus the extension (or an empty string if no file is open) %u => link URL (or an empty string if not over a URL link) %p => current page number (or an empty string if no file is open) %x => selection upper-left x coordinate (or 0 if there is no selection) %y => selection upper-left y coordinate (or 0 if there is no selection) %X => selection lower-right x coordinate (or 0 if there is no selection) %Y => selection lower-right y coordinate (or 0 if there is no selection) %i => page containing the mouse pointer %j => x coordinate of the mouse pointer %k => y coordinate of the mouse pointer %% => % openOutline Open the outline pane. closeOutline Close the outline pane. toggleOutline Toggle the outline pane between open and closed. scrollOutlineDown(n) Scroll the outline down by n increments. scrollOutlineUp(n) Scroll the outline up by n increments. focusToDocWin Set the keyboard focus to the main document window. focusToPageNum Set the keyboard focus to the page number text box. find Open the 'find' dialog. findNext Finds the next occurrence of the search string (no dialog). print Open the 'print' dialog. about Open the 'about' dialog. quit Quit from xpdf. The following commands depend on the current mouse position: startSelection Start a selection, which will be extended as the mouse moves. endSelection End a selection. startPan Start a pan, which will scroll the document as the mouse moves endPan End a pan. postPopupMenu Display the popup menu. followLink Follow a hyperlink (does nothing if the mouse is not over a link). followLinkInNewWin Follow a hyperlink, opening PDF files in a new window (does nothing if the mouse is not over a link). For links to non-PDF files, this command is identical to followLink. followLinkNoSel Same as followLink, but does nothing if there is a non-empty selection. (This is useful as a mouse button binding.) followLinkInNewWinNoSel Same as followLinkInNewWin, but does nothing if there is a non- empty selection. (This is useful as a mouse button binding.) Default Bindings The default mouse bindings are as follows: bind mousePress1 any startSelection bind mouseRelease1 any endSelection followLinkNoSel bind mousePress2 any startPan bind mouseRelease2 any endPan bind mousePress3 any postPopupMenu bind mousePress4 any scrollUpPrevPage(16) bind mousePress5 any scrollDownNextPage(16) bind mousePress6 any scrollLeft(16) bind mousePress7 any scrollRight(16) The default key bindings are as follows: bind ctrl-home any gotoPage(1) bind home any scrollToTopLeft bind ctrl-end any gotoLastPage bind end any scrollToBottomRight bind pgup any pageUp bind backspace any pageUp bind delete any pageUp bind pgdn any pageDown bind space any pageDown bind left any scrollLeft(16) bind right any scrollRight(16) bind up any scrollUp(16) bind down any scrollDown(16) bind o any open bind O any open bind r any reload bind R any reload bind f any find bind F any find bind ctrl-f any find bind ctrl-g any findNext bind ctrl-p any print bind n scrLockOff nextPage bind N scrLockOff nextPage bind n scrLockOn nextPageNoScroll bind N scrLockOn nextPageNoScroll bind p scrLockOff prevPage bind P scrLockOff prevPage bind p scrLockOn prevPageNoScroll bind P scrLockOn prevPageNoScroll bind v any goForward bind b any goBackward bind g any focusToPageNum bind 0 any zoomPercent(125) bind + any zoomIn bind - any zoomOut bind z any zoomFitPage bind w any zoomFitWidth bind alt-f any toggleFullScreenMode bind ctrl-l any redraw bind ctrl-w any closeWindow bind ? any about bind q any quit bind Q any quit Previous versions of xpdf included a "viKeys" X resource. It is no longer available, but the following bindings are equivalent: bind h any scrollLeft(16) bind l any scrollRight(16) bind k any scrollUp(16) bind j any scrollDown(16) () 2 REMOTE_SERVER_MODE Xpdf can be started in remote server mode by specifying a server name (in addition to the file name and page number). For example: xpdf -remote myServer file.pdf If there is currently no xpdf running in server mode with the name 'myServer', a new xpdf window will be opened. If another command: xpdf -remote myServer another.pdf 9 is issued, a new copy of xpdf will not be started. Instead, the first xpdf (the server) will load another.pdf and display page nine. If the file name is the same: xpdf -remote myServer another.pdf 4 the xpdf server will simply display the specified page. The -raise option tells the server to raise its window; it can be spec- ified with or without a file name and page number. The -quit option tells the server to close its window and exit. () 2 XIT_CODE The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error.

If .I PS-file is not specified, pdftops converts .I file.pdf to .I file.ps (or .I file.eps with the \-eps option). If .I PS-file is \'-', the PostScript is sent to stdout. .SH CONFIGURATION FILE Pdftops reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftops is built). See the .BR xpdfrc (5) man page for details. .SH OPTIONS Many of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option. .TP .BI \-f " number" Specifies the first page to print. .TP .BI \-l " number" Specifies the last page to print. .TP .B \-level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. No more than one of the PostScript level options (\-level1, \-level1sep, \-level2, \-level2sep, \-level3, \-level3Sep) may be given. .RB "[config file: " psLevel ] .TP .B \-level1sep Generate Level 1 separable PostScript. All colors are converted to CMYK. Images are written with separate stream data for the four components. .RB "[config file: " psLevel ] .TP .B \-level2 Generate Level 2 PostScript. Level 2 supports color images and image compression. This is the default setting. .RB "[config file: " psLevel ] .TP .B \-level2sep Generate Level 2 separable PostScript. All colors are converted to CMYK. The PostScript separation convention operators are used to handle custom (spot) colors. .RB "[config file: " psLevel ] .TP .B \-level3 Generate Level 3 PostScript. This enables all Level 2 features plus CID font embedding and masked image generation. .RB "[config file: " psLevel ] .TP .B \-level3Sep Generate Level 3 separable PostScript. The separation handling is the same as for \-level2Sep. .RB "[config file: " psLevel ] .TP .B \-eps Generate an Encapsulated PostScript (EPS) file. An EPS file contains a single image, so if you use this option with a multi-page PDF file, you must use \-f and \-l to specify a single page. No more than one of the mode options (\-eps, \-form) may be given. .TP .B \-form Generate a PostScript form which can be imported by software that understands forms. A form contains a single page, so if you use this option with a multi-page PDF file, you must use \-f and \-l to specify a single page. The \-level1 option cannot be used with \-form. .TP .B \-opi Generate OPI comments for all images and forms which have OPI information. (This option is only available if pdftops was compiled with OPI support.) .RB "[config file: " psOPI ] .TP .B \-noembt1 By default, any Type 1 fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make PostScript files larger, but may be necessary for readable output. .RB "[config file: " psEmbedType1Fonts ] .TP .B \-noembtt By default, any TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make PostScript files larger, but may be necessary for readable output. Also, some PostScript interpreters do not have TrueType rasterizers. .RB "[config file: " psEmbedTrueTypeFonts ] .TP .B \-noembcidps By default, any CID PostScript fonts which are embedded in the PDF file are copied into the PostScript file. This option disables that embedding. No attempt is made to substitute for non-embedded CID PostScript fonts. .RB "[config file: " psEmbedCIDPostScriptFonts ] .TP .B \-noembcidtt By default, any CID TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option disables that embedding. No attempt is made to substitute for non-embedded CID TrueType fonts. .RB "[config file: " psEmbedCIDTrueTypeFonts ] .TP .B \-preload Convert PDF forms to PS procedures, and preload image data. This uses more memory in the PostScript interpreter, but generates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. .TP .BI \-paper " size" Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. .RB "[config file: " psPaperSize ] .TP .BI \-paperw " size" Set the paper width, in points. .RB "[config file: " psPaperSize ] .TP .BI \-paperh " size" Set the paper height, in points. .RB "[config file: " psPaperSize ] .TP .B \-nocrop By default, output is cropped to the CropBox specified in the PDF file. This option disables cropping. .RB "[config file: " psCrop ] .TP .B \-expand Expand PDF pages smaller than the paper to fill the paper. By default, these pages are not scaled. .RB "[config file: " psExpandSmaller ] .TP .B \-noshrink Don't scale PDF pages which are larger than the paper. By default, pages larger than the paper are shrunk to fit. .RB "[config file: " psShrinkLarger ] .TP .B \-nocenter By default, PDF pages smaller than the paper (after any scaling) are centered on the paper. This option causes them to be aligned to the lower-left corner of the paper instead. .RB "[config file: " psCenter ] .TP .B \-pagecrop Treat the CropBox as the PDF page size. By default, the MediaBox is used as the page size. .TP .B \-duplex Set the Duplex pagedevice entry in the PostScript file. This tells duplex-capable printers to enable duplexing. .RB "[config file: " psDuplex ] .TP .BI \-opw " password" Specify the owner password for the PDF file. Providing this will bypass all security restrictions. .TP .BI \-upw " password" Specify the user password for the PDF file. .TP .B \-q Don't print any messages or errors. .RB "[config file: " errQuiet ] .TP .BI \-cfg " config-file" Read .I config-file in place of ~/.xpdfrc or the system-wide config file. .TP .B \-v Print copyright and version information. .TP .B \-h Print usage information. .RB ( \-help and .B \-\-help are equivalent.) .SH EXIT CODES The Xpdf tools use the following exit codes: .TP 0 No error. .TP 1 Error opening a PDF file. .TP 2 Error opening an output file. .TP 3 Error related to PDF permissions. .TP 99 Other error. .SH AUTHOR The pdftops software and documentation are copyright 1996-2011 Glyph & Cog, LLC. .SH "SEE ALSO" .BR xpdf (1), .BR pdftotext (1), .BR pdfinfo (1), .BR pdffonts (1), .BR pdfdetach (1), .BR pdftoppm (1), .BR pdfimages (1), .BR xpdfrc (5) .br .B http://www.foolabs.com/xpdf/ xpdf-3.03/doc/xpdfrc.hlp0000644000076400007640000007146211622305345014465 0ustar dereknderekn!

The effect of this is equivalent to inserting the contents of config-file directly into the parent config file in place of the include command. Config files can be nested arbitrarily deeply. () 2 HARACTER_MAPPIN nameToUnicode map-file Specifies a file with the mapping from character names to Uni- code. This is used to handle PDF fonts that have valid encod- ings but no ToUnicode entry. Each line of a nameToUnicode file looks like this: hex-string name The hex-string is the Unicode (UCS-2) character index, and name is the corresponding character name. Multiple nameToUnicode files can be used; if a character name is given more than once, the code in the last specified file is used. There is a built- in default nameToUnicode table with all of Adobe's standard character names. cidToUnicode registry-ordering map-file Specifies the file with the mapping from character collection to Unicode. Each line of a cidToUnicode file represents one char- acter: hex-string The hex-string is the Unicode (UCS-2) index for that character. The first line maps CID 0, the second line CID 1, etc. File size is determined by size of the character collection. Only one file is allowed per character collection; the last specified file is used. There are no built-in cidToUnicode mappings. unicodeToUnicode font-name-substring map-file This is used to work around PDF fonts which have incorrect Uni- code information. It specifies a file which maps from the given (incorrect) Unicode indexes to the correct ones. The mapping will be used for any font whose name contains font-name-sub- string. Each line of a unicodeToUnicode file represents one Unicode character: in-hex out-hex1 out-hex2 ... The in-hex field is an input (incorrect) Unicode index, and the rest of the fields are one or more output (correct) Unicode indexes. Each occurrence of in-hex will be converted to the specified output sequence. unicodeMap encoding-name map-file Specifies the file with mapping from Unicode to encoding-name. These encodings are used for text output (see below). Each line of a unicodeMap file represents a range of one or more Unicode characters which maps linearly to a range in the output encod- ing: in-start-hex in-end-hex out-start-hex Entries for single characters can be abbreviated to: in-hex out-hex The in-start-hex and in-end-hex fields (or the single in-hex field) specify the Unicode range. The out-start-hex field (or the out-hex field) specifies the start of the output encoding range. The length of the out-start-hex (or out-hex) string determines the length of the output characters (e.g., UTF-8 uses different numbers of bytes to represent characters in different ranges). Entries must be given in increasing Unicode order. Only one file is allowed per encoding; the last specified file is used. The Latin1, ASCII7, Symbol, ZapfDingbats, UTF-8, and UCS-2 encodings are predefined. cMapDir registry-ordering dir Specifies a search directory, dir, for CMaps for the reg- istry-ordering character collection. There can be multiple directories for a particular collection. There are no default CMap directories. toUnicodeDir dir Specifies a search directory, dir, for ToUnicode CMaps. There can be multiple ToUnicode directories. There are no default ToUnicode directories. () 2 ENERAL_FONT_CONFIGURATIO fontFile PDF-font-name font-file Maps a PDF font, PDF-font-name, to a font for display or Post- Script output. The font file, font-file, can be any type allowed in a PDF file. This command can be used for 8-bit or 16-bit (CID) fonts. fontDir dir Specifies a search directory for font files. There can be mul- tiple fontDir commands; all of the specified directories will be searched in order. The font files can be Type 1 (.pfa or .pfb) or TrueType (.ttf or .ttc); other files in the directory will be ignored. The font file name (not including the extension) must exactly match the PDF font name. This search is performed if the font name doesn't match any of the fonts declared with the fontFile command. There are no default fontDir directories. fontFileCC registry-ordering font-file Maps the registry-ordering character collection to a font for display or PostScript output. This mapping is used if the font name doesn't match any of the fonts declared with the fontFile, fontDir, psResidentFont16, or psResidentFontCC commands. () 2 OSTSCRIPT_FONT_CONFIGURATIO psFontPassthrough yes | no If set to "yes", pass 8-bit font names through to the PostScript output without substitution. Fonts which are not embedded in the PDF file are expected to be available on the printer. This defaults to "no". psResidentFont PDF-font-name PS-font-name When the 8-bit font PDF-font-name is used (without embedding) in a PDF file, it will be translated to the PostScript font PS-font-name, which is assumed to be resident in the printer. Typically, PDF-font-name and PS-font-name are the same. By default, only the Base-14 fonts are assumed to be resident. psResidentFont16 PDF-font-name wMode PS-font-name encoding When the 16-bit (CID) font PDF-font-name with writing mode wMode is used (without embedding) in a PDF file, it will be translated to the PostScript font PS-font-name, which is assumbed to be resident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the specified encoding (which must have been defined with the unicodeMap command). psResidentFontCC registry-ordering wMode PS-font-name encoding When a 16-bit (CID) font using the registry-ordering character collection and wMode writing mode is used (without embedding) in a PDF file, the PostScript font, PS-font-name, is substituted for it. The substituted font is assumbed to be resident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the spec- ified encoding (which must have been defined with the unicodeMap command). psEmbedType1Fonts yes | no If set to "no", prevents embedding of Type 1 fonts in generated PostScript. This defaults to "yes". psEmbedTrueTypeFonts yes | no If set to "no", prevents embedding of TrueType fonts in gener- ated PostScript. This defaults to "yes". psEmbedCIDTrueTypeFonts yes | no If set to "no", prevents embedding of CID TrueType fonts in gen- erated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". psEmbedCIDPostScriptFonts yes | no If set to "no", prevents embedding of CID PostScript fonts in generated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". () 2 OSTSCRIPT_CONTRO psPaperSize width(pts) height(pts) Sets the paper size for PostScript output. The width and height parameters give the paper size in PostScript points (1 point = 1/72 inch). psPaperSize letter | legal | A4 | A3 | match Sets the paper size for PostScript output to a standard size. The default paper size is set when xpdf and pdftops are built, typically to "letter" or "A4". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. psImageableArea llx lly urx ury Sets the imageable area for PostScript output. The four inte- gers are the coordinates of the lower-left and upper-right cor- ners of the imageable region, specified in points (with the ori- gin being the lower-left corner of the paper). This defaults to the full paper size; the psPaperSize option will reset the imageable area coordinates. psCrop yes | no If set to "yes", PostScript output is cropped to the CropBox specified in the PDF file; otherwise no cropping is done. This defaults to "yes". psExpandSmaller yes | no If set to "yes", PDF pages smaller than the PostScript imageable area are expanded to fill the imageable area. Otherwise, no scalling is done on smaller pages. This defaults to "no". psShrinkLarger yes | no If set to yes, PDF pages larger than the PostScript imageable area are shrunk to fit the imageable area. Otherwise, no scal- ing is done on larger pages. This defaults to "yes". psCenter yes | no If set to yes, PDF pages smaller than the PostScript imageable area (after any scaling) are centered in the imageable area. Otherwise, they are aligned at the lower-left corner of the imageable area. This defaults to "yes". psDuplex yes | no If set to "yes", the generated PostScript will set the "Duplex" pagedevice entry. This tells duplex-capable printers to enable duplexing. This defaults to "no". psLevel level1 | level1sep | level2 | level2sep | level3 | level3Sep Sets the PostScript level to generate. This defaults to "level2". psPreload yes | no If set to "yes", PDF forms are converted to PS procedures, and image data is preloaded. This uses more memory in the Post- Script interpreter, but generates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. This defaults to "no". psOPI yes | no If set to "yes", generates PostScript OPI comments for all images and forms which have OPI information. This option is only available if the Xpdf tools were compiled with OPI support. This defaults to "no". psASCIIHex yes | no If set to "yes", the ASCIIHexEncode filter will be used instead of ASCII85Encode for binary data. This defaults to "no". psUncompressPreloadedImages yes | no If set to "yes", all preloaded images in PS files will uncom- pressed. If set to "no", the original compressed images will be used when possible. The "yes" setting is useful to work around certain buggy PostScript interpreters. This defaults to "no". psRasterResolution float Set the resolution (in dpi) for rasterized pages in PostScript output. (Pdftops will rasterize pages which use transparency.) This defaults to 300. psRasterMono yes | no If set to "yes", rasterized pages in PS files will be monochrome (8-bit gray) instead of color. This defaults to "no". psAlwaysRasterize yes | no If set to "yes", all PostScript output will be rasterized. This defaults to "no". psFile file-or-command Sets the default PostScript file or print command for xpdf. Commands start with a '|' character; anything else is a file. If the file name or command contains spaces it must be quoted. This defaults to unset, which tells xpdf to generate a name of the form .ps for a PDF file .pdf. fontDir dir See the description above, in the DISPLAY FONTS section. () 2 EXT_CONTRO textEncoding encoding-name Sets the encoding to use for text output. (This can be overrid- den with the "-enc" switch on the command line.) The encod- ing-name must be defined with the unicodeMap command (see above). This defaults to "Latin1". textEOL unix | dos | mac Sets the end-of-line convention to use for text output. The options are: unix = LF dos = CR+LF mac = CR (This can be overridden with the "-eol" switch on the command line.) The default value is based on the OS where xpdf and pdftotext were built. textPageBreaks yes | no If set to "yes", text extraction will insert page breaks (form feed characters) between pages. This defaults to "yes". textKeepTinyChars yes | no If set to "yes", text extraction will keep all characters. If set to "no", text extraction will discard tiny (smaller than 3 point) characters after the first 50000 per page, avoiding extremely slow run times for PDF files that use special fonts to do shading or cross-hatching. This defaults to "no". () 2 ISCELLANEOUS_SETTING initialZoom percentage | page | width Sets the initial zoom factor. A number specifies a zoom per- centage, where 100 means 72 dpi. You may also specify 'page', to fit the page to the window size, or 'width', to fit the page width to the window width. continuousView yes | no If set to "yes", xpdf will start in continuous view mode, i.e., with one vertical screoll bar for the whole document. This defaults to "no". enableT1lib yes | no Enables or disables use of t1lib (a Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with t1lib support. ("enableT1lib" replaces the old "t1libControl" option.) This option defaults to "yes". enableFreeType yes | no Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". enableFreeType yes | no Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". disableFreeTypeHinting yes | no If this is set to "yes", FreeType hinting will be forced off. This option defaults to "no". antialias yes | no Enables or disables font anti-aliasing in the PDF rasterizer. This option affects all font rasterizers. ("antialias" replaces the anti-aliasing control provided by the old "t1libControl" and "freetypeControl" options.) This default to "yes". vectorAntialias yes | no Enables or disables anti-aliasing of vector graphics in the PDF rasterizer. This defaults to "yes". antialiasPrinting yes | no If this is "yes", bitmaps sent to the printer will be antialiased (according to the "antialias" and "vectorAntialias" settings). If this is "no", printed bitmaps will not be antialiased. This defaults to "no". strokeAdjust yes | no Enables or disables stroke adjustment. Stroke adjustment moves horizontal and vertical lines by up to half a pixel to make them look "cleaner" when vector anti-aliasing is enabled. This defaults to "yes". screenType dispersed | clustered | stochasticClustered Sets the halftone screen type, which will be used when generat- ing a monochrome (1-bit) bitmap. The three options are dis- persed-dot dithering, clustered-dot dithering (with a round dot and 45-degree screen angle), and stochastic clustered-dot dithering. By default, "stochasticClustered" is used for reso- lutions of 300 dpi and higher, and "dispersed" is used for reso- lutions lower then 300 dpi. screenSize integer Sets the size of the (square) halftone screen threshold matrix. By default, this is 4 for dispersed-dot dithering, 10 for clus- tered-dot dithering, and 100 for stochastic clustered-dot dithering. screenDotRadius integer Sets the halftone screen dot radius. This is only used when screenType is set to stochasticClustered, and it defaults to 2. In clustered-dot mode, the dot radius is half of the screen size. Dispersed-dot dithering doesn't have a dot radius. screenGamma float Sets the halftone screen gamma correction parameter. Gamma val- ues greater than 1 make the output brighter; gamma values less than 1 make it darker. The default value is 1. screenBlackThreshold float When halftoning, all values below this threshold are forced to solid black. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 0. screenWhiteThreshold float When halftoning, all values above this threshold are forced to solid white. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 1. minLineWidth float Set the minimum line width, in device pixels. This affects the rasterizer only, not the PostScript converter (except when it uses rasterization to handle transparency). The default value is 0 (no minimum). drawAnnotations yes | no If set to "no", annotations will not be drawn or printed. The default value is "yes". overprintPreview yes | no If set to "yes", generate overprint preview output, honoring the OP/op/OPM settings in the PDF file. Ignored for non-CMYK out- put. The default value is "no". launchCommand command Sets the command executed when you click on a "launch"-type link. The intent is for the command to be a program/script which determines the file type and runs the appropriate viewer. The command line will consist of the file to be launched, fol- lowed by any parameters specified with the link. Do not use "%s" in "command". By default, this is unset, and Xpdf will simply try to execute the file (after prompting the user). urlCommand command Sets the command executed when you click on a URL link. The string "%s" will be replaced with the URL. (See the example below.) This has no default value. movieCommand command Sets the command executed when you click on a movie annotation. The string "%s" will be replaced with the movie file name. This has no default value. mapNumericCharNames yes | no If set to "yes", the Xpdf tools will attempt to map various numeric character names sometimes used in font subsets. In some cases this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "yes". mapUnknownCharNames yes | no If set to "yes", and mapNumericCharNames is set to "no", the Xpdf tools will apply a simple pass-through mapping (Unicode index = character code) for all unrecognized glyph names. (For CID fonts, setting mapNumericCharNames to "no" is unnecessary.) In some cases, this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "no". bind modifiers-key context command ... Add a key or mouse button binding. Modifiers can be zero or more of: shift- ctrl- alt- Key can be a regular ASCII character, or any one of: space tab return enter backspace insert delete home end pgup pgdn left / right / up / down (arrow keys) f1 .. f35 (function keys) mousePress1 .. mousePress7 (mouse buttons) mouseRelease1 .. mouseRelease7 (mouse buttons) Context is either "any" or a comma-separated combination of: fullScreen / window (full screen mode on/off) continuous / singlePage (continuous mode on/off) overLink / offLink (mouse over link or not) scrLockOn / scrLockOff (scroll lock on/off) The context string can include only one of each pair in the above list. Command is an Xpdf command (see the COMMANDS section of the xpdf(1) man page for details). Multiple commands are separated by whitespace. The bind command replaces any existing binding, but only if it was defined for the exact same modifiers, key, and context. All tokens (modifiers, key, context, commands) are case-sensitive. Example key bindings: # bind ctrl-a in any context to the nextPage # command bind ctrl-a any nextPage # bind uppercase B, when in continuous mode # with scroll lock on, to the reload command # followed by the prevPage command bind B continuous,scrLockOn reload prevPage See the xpdf(1) man page for more examples. unbind modifiers-key context Removes a key binding established with the bind command. This is most useful to remove default key bindings before establish- ing new ones (e.g., if the default key binding is given for "any" context, and you want to create new key bindings for mul- tiple contexts). printCommands yes | no If set to "yes", drawing commands are printed as they're exe- cuted (useful for debugging). This defaults to "no". errQuiet yes | no If set to "yes", this suppresses all error and warning messages from all of the Xpdf tools. This defaults to "no".

Pdftotext reads the PDF file, PDF-file, and writes a text file, text- file. If text-file is not specified, pdftotext converts file.pdf to file.txt. If text-file is '-', the text is sent to stdout. CONFIGURATION FILE Pdftotext reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftotext is built). See the xpdfrc(5) man page for details. OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to convert. -l number Specifies the last page to convert. -layout Maintain (as best as possible) the original physical layout of the text. The default is to 'undo' physical layout (columns, hyphenation, etc.) and output the text in reading order. -fixed number Assume fixed-pitch (or tabular) text, with the specified charac- ter width (in points). This forces physical layout mode. -raw Keep the text in content stream order. This is a hack which often "undoes" column formatting, etc. Use of raw mode is no longer recommended. -htmlmeta Generate a simple HTML file, including the meta information. This simply wraps the text in 
 and
and prepends the meta headers. -enc encoding-name Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). The encoding name is case-sensitive. This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding] -eol unix | dos | mac Sets the end-of-line convention to use for text output. [config file: textEOL] -nopgbrk Don't insert page breaks (form feed characters) between pages. [config file: textPageBreaks] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) BUGS Some PDF files contain fonts whose encodings have been mangled beyond recognition. There is no way (short of OCR) to extract text from these files. EXIT CODES The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error.

(These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) Xpdf runs under the X Window System on UNIX, VMS, and OS/2. To run xpdf, simply type: xpdf file.pdf where file.pdf is your PDF file. The file name can be followed by a number specifying the page which should be displayed first, e.g.: xpdf file.pdf 18 You can also give a named destination, prefixed with '+' in place of the page number. (This is only useful with PDF files that provide named destination targets.) You can also start xpdf without opening any files: xpdf CONFIGURATION FILE Xpdf reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when xpdf is built). See the xpdfrc(5) man page for details. OPTIONS Many of the following options can be set with configuration file com- mands or X resources. These are listed in square brackets with the description of the corresponding command line option. -g geometry Set the initial window geometry. (-geometry is equivalent.) [X resource: xpdf.geometry] -title title Set the window title. By default, the title will be "xpdf: foo.pdf". [X resource: xpdf.title] -cmap Install a private colormap. This is ignored on TrueColor visu- als. [X resource: xpdf.installCmap] -rgb number Set the size of largest RGB cube xpdf will try to allocate. The default is 5 (for a 5x5x5 cube); set to a smaller number to con- serve color table entries. This is ignored with private col- ormaps and on TrueColor visuals. [X resource: xpdf.rgbCubeSize] -rv Set reverse video mode. This reverses the colors of everything except images. It may not always produce great results for PDF files which do weird things with color. This also causes the paper color to default to black. [X resource: xpdf.reverseV- ideo] -papercolor color Set the "paper color", i.e., the background of the page display. This will not work too well with PDF files that do things like filling in white behind the text. [X resource: xpdf.paperColor] -mattecolor color Set the matte color, i.e., the color used for background outside the actual page area. (There is a separate setting, xpdf.fullScreenMatteColor, for full-screen mode.) [X resource: xpdf.matteColor] -z zoom Set the initial zoom factor. A number specifies a zoom percent- age, where 100 means 72 dpi. You may also specify 'page', to fit the page to the window size, or 'width', to fit the page width to the window width. [config file: initialZoom; or X resource: xpdf.initialZoom] -cont Start in continuous view mode, i.e., with one vertical scroll bar for the whole document. [config file: continuousView] -t1lib yes | no Enable or disable t1lib (a Type 1 font rasterizer). This defaults to "yes". [config file: enableT1lib] -freetype yes | no Enable or disable FreeType (a TrueType / Type 1 font raster- izer). This defaults to "yes". [config file: enableFreeType] -aa yes | no Enable or disable font anti-aliasing. This defaults to "yes". [config file: antialias] -aaVector yes | no Enable or disable vector anti-aliasing. This defaults to "yes". [config file: vectorAntialias] -ps PS-file Set the default file name for PostScript output (i.e., the name which will appear in the print dialog). This can also be of the form '|command' to pipe the PostScript through a command. [con- fig file: psFile] -paper size Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. [config file: psPaperSize] -paperw size Set the paper width, in points. [config file: psPaperSize] -paperh size Set the paper height, in points. [config file: psPaperSize] -level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. [config file: psLevel] -enc encoding-name Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [con- fig file: textEncoding] -eol unix | dos | mac Sets the end-of-line convention to use for text output. [config file: textEOL] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -fullscreen Open xpdf in full-screen mode, useful for presentations. -remote name Start/contact xpdf remote server with specified name (see the REMOTE SERVER MODE section below). -exec command Execute a command (see the COMMANDS section below) in an xpdf remote server window (with -remote only). -reload Reload xpdf remote server window (with -remote only). -raise Raise xpdf remote server window (with -remote only). -quit Kill xpdf remote server (with -remote only). -cmd Print commands as they're executed (useful for debugging). [config file: printCommands] -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) Several other standard X options and resources will work as expected: -display display [X resource: xpdf.display] -fg color (-foreground is equivalent.) [X resource: xpdf*Foreground] -bg color (-background is equivalent.) [X resource: xpdf*Background] -font font (-fn is equivalent.) [X resource: xpdf*fontList] The color and font options only affect the user interface elements, not the PDF display (the 'paper'). The following X resources do not have command line option equivalents: xpdf.toolTipEnable Enables (if set to true) or disables (if set to false) the tool- tips on the toolbar buttons. xpdf.fullScreenMatteColor Sets the matte color to be used in full-screen mode. The default setting is "black". CONTROLS On-screen controls, at the bottom of the xpdf window left/right arrow buttons Move to the previous/next page. double left/right arrow buttons Move backward or forward by ten pages. dashed left/right arrow buttons Move backward or forward along the history path. 'Page' entry box Move to a specific page number. Click in the box to activate it, type the page number, then hit return. zoom popup menu Change the zoom factor (see the description of the -z option above). binoculars button Find a text string. print button Bring up a dialog for generating a PostScript file. The dialog has options to set the pages to be printed and the PostScript file name. The file name can be '-' for stdout or '|command' to pipe the PostScript through a command, e.g., '|lpr'. '?' button Bring up the 'about xpdf' window. link info The space between the '?' and 'Quit' buttons is used to show the URL or external file name when the mouse is over a link. 'Quit' button Quit xpdf. Menu Pressing the right mouse button will post a popup menu with the follow- ing commands: Open... Open a new PDF file via a file requester. Open in new window... Create a new window and open a new PDF file via a file requester. Reload Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. Save as... Save the current file via a file requester. Continuous view Toggles between single page and continuous view modes. Rotate counterclockwise Rotate the page 90 degrees counterclockwise. Rotate clockwise Rotate the page 90 degrees clockwise. The two rotate commands are intended primarily for PDF files where the rotation isn't correctly specified in the file. Zoom to selection Zoom in to the currently selected rectangle. Close Close the current window. If this is the only open window, the document is closed, but the window is left open (i.e., this menu command won't quit xpdf). Quit Quit xpdf. Outline If the PDF contains an outline (a.k.a., bookmarks), there will be an outline pane on the left side of the window. The width of the outline pane is adjustable with a vertical split bar via the knob near its bot- tom end. Text selection Dragging the mouse with the left button held down will highlight an arbitrary rectangle. Any text inside this rectangle will be copied to the X selection buffer. Links Clicking on a hyperlink will jump to the link's destination. A link to another PDF document will make xpdf load that document. A 'launch' link to an executable program will display a dialog, and if you click 'ok', execute the program. URL links call an external command (see the WEB BROWSERS section below). Panning Dragging the mouse with the middle button held down pans the window. Key bindings o Open a new PDF file via a file requester. r Reload the current PDF file. Note that Xpdf will reload the file automatically (on a page change or redraw) if it has changed since it was last loaded. control-L Redraw the current page. control-W Close the current window. f or control-F Find a text string. control-G Find next occurrence. control-P Print. n Move to the next page.

Scroll to top of current page. Scroll to bottom of current page. control- Scroll to first page of document. control- Scroll to last page of document. arrows Scroll the current page. g Activate the page number text field ("goto page"). 0 Set the zoom factor to 125%. + Zoom in (increment the zoom factor by 1). - Zoom out (decrement the zoom factor by 1). z Set the zoom factor to 'page' (fit page to window). w Set the zoom factor to 'width' (fit page width to window). alt-F Toggle full-screen mode. q Quit xpdf. WEB BROWSERS If you want to run xpdf automatically from netscape or mosaic (and probably other browsers) when you click on a link to a PDF file, you need to edit (or create) the files .mime.types and .mailcap in your home directory. In .mime.types add the line: application/pdf pdf In .mailcap add the lines: # Use xpdf to view PDF files. application/pdf; xpdf -q %s Make sure that xpdf is on your executable search path. When you click on a URL link in a PDF file, xpdf will execute the com- mand specified by the urlCommand config file option, replacing an occurrence of '%s' with the URL. For example, to call netscape with the URL, add this line to your config file: urlCommand "netscape -remote 'openURL(%s)'" COMMANDS Xpdf's key and mouse bindings are user-configurable, using the bind and unbind options in the config file (see xpdfrc(5)). The bind command allows you to bind a key or mouse button to a sequence of one or more commands. Available Commands The following commands are supported: gotoPage(page) Go to the specified page. gotoPageNoScroll(page) Go to the specified page, with the current relative scroll posi- tion. gotoDest(dest) Go to a named destination. gotoLastPage Go to the last page in the PDF file. gotoLastPageNoScroll Go to the last page in the PDF file, with the current relative scroll position. nextPage Go to the next page. nextPageNoScroll Go to the next page, with the current relative scroll position. prevPage Go to the previous page. prevPageNoScroll Go to the previous page, with the current relative scroll posi- tion. pageUp Scroll up by one screenful. pageDown Scroll down by one screenful. scrollLeft(n) Scroll left by n pixels. scrollRight(n) Scroll right by n pixels. scrollUp(n) Scroll up by n pixels. scrollDown(n) Scroll down by n pixels. scrollUpPrevPage(n) Scroll up by n pixels, moving to the previous page if appropri- ate. scrollDownPrevPage(n) Scroll down by n pixels, moving to the next page if appropriate. scrollToTopEdge Scroll to the top edge of the current page, with no horizontal movement. scrollToBottomEdge Scroll to the bottom edge of the current page, with no horizon- tal movement. scrollToLeftEdge Scroll to the left edge of the current page, with no vertical movement. scrollToRightEdge Scroll to the right edge of the current page, with no vertical movement. scrollToTopLeft Scroll to the top-left corner of the current page. scrollToBottomRight Scroll to the bottom-right corner of the current page. goForward Move forward along the history path. goBackward Move backward along the history path. zoomPercent(z) Set the zoom factor to z%. zoomFitPage Set the zoom factor to fit-page. zoomFitWidth Set the zoom factor to fit-width. zoomIn Zoom in - go to the next higher zoom factor. zoomOut Zoom out - go the next lower zoom factor. rotateCW Rotate the page 90 degrees clockwise. rotateCCW Rotate the page 90 degrees counterclockwise. setSelection(pg,ulx,uly,lrx,lry) Set the selection to the specified coordinates on the specified page. continuousMode Go to continuous view mode. singlePageMode Go to single-page view mode. toggleContinuousMode Toggle between continuous and single page view modes. fullScreenMode Go to full-screen mode. windowMode Go to window (non-full-screen) mode. toggleFullScreenMode Toggle between full-screen and window modes. open Open a PDF file in this window, using the open dialog. openInNewWin Open a PDF file in a new window, using the open dialog. openFile(file) Open a specified PDF file in this window. openFileInNewWin(file) Open a specified PDF file in a new window. openFileAtDest(file,dest) Open a specified PDF file in this window and go to a named des- tination. openFileAtDestInNewWin(file,dest) Open a specified PDF file in a new window and go to a named des- tination. reload Reload the current PDF file. redraw Redraw the window. raise Raise the window to the front. closeWindow Close the window. run(external-command-string) Run an external command.

The following commands depend on the current mouse position: startSelection Start a selection, which will be extended as the mouse moves. endSelection End a selection. startPan Start a pan, which will scroll the document as the mouse moves endPan End a pan. postPopupMenu Display the popup menu. followLink Follow a hyperlink (does nothing if the mouse is not over a link). followLinkInNewWin Follow a hyperlink, opening PDF files in a new window (does nothing if the mouse is not over a link). For links to non-PDF files, this command is identical to followLink. followLinkNoSel Same as followLink, but does nothing if there is a non-empty selection. (This is useful as a mouse button binding.) followLinkInNewWinNoSel Same as followLinkInNewWin, but does nothing if there is a non- empty selection. (This is useful as a mouse button binding.) Default Bindings The default mouse bindings are as follows: bind mousePress1 any startSelection bind mouseRelease1 any endSelection followLinkNoSel bind mousePress2 any startPan bind mouseRelease2 any endPan bind mousePress3 any postPopupMenu bind mousePress4 any scrollUpPrevPage(16) bind mousePress5 any scrollDownNextPage(16) bind mousePress6 any scrollLeft(16) bind mousePress7 any scrollRight(16) The default key bindings are as follows: bind ctrl-home any gotoPage(1) bind home any scrollToTopLeft bind ctrl-end any gotoLastPage bind end any scrollToBottomRight bind pgup any pageUp bind backspace any pageUp bind delete any pageUp bind pgdn any pageDown bind space any pageDown bind left any scrollLeft(16) bind right any scrollRight(16) bind up any scrollUp(16) bind down any scrollDown(16) bind o any open bind O any open bind r any reload bind R any reload bind f any find bind F any find bind ctrl-f any find bind ctrl-g any findNext bind ctrl-p any print bind n scrLockOff nextPage bind N scrLockOff nextPage bind n scrLockOn nextPageNoScroll bind N scrLockOn nextPageNoScroll bind p scrLockOff prevPage bind P scrLockOff prevPage bind p scrLockOn prevPageNoScroll bind P scrLockOn prevPageNoScroll bind v any goForward bind b any goBackward bind g any focusToPageNum bind 0 any zoomPercent(125) bind + any zoomIn bind - any zoomOut bind z any zoomFitPage bind w any zoomFitWidth bind alt-f any toggleFullScreenMode bind ctrl-l any redraw bind ctrl-w any closeWindow bind ? any about bind q any quit bind Q any quit Previous versions of xpdf included a "viKeys" X resource. It is no longer available, but the following bindings are equivalent: bind h any scrollLeft(16) bind l any scrollRight(16) bind k any scrollUp(16) bind j any scrollDown(16) REMOTE SERVER MODE Xpdf can be started in remote server mode by specifying a server name (in addition to the file name and page number). For example: xpdf -remote myServer file.pdf If there is currently no xpdf running in server mode with the name 'myServer', a new xpdf window will be opened. If another command: xpdf -remote myServer another.pdf 9 is issued, a new copy of xpdf will not be started. Instead, the first xpdf (the server) will load another.pdf and display page nine. If the file name is the same: xpdf -remote myServer another.pdf 4 the xpdf server will simply display the specified page. The -raise option tells the server to raise its window; it can be spec- ified with or without a file name and page number. The -quit option tells the server to close its window and exit. EXIT CODES The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error.

If you have a .xpdfrc file in your home directory, it will be read. Otherwise, a system-wide configuration file will be read from /usr/local/etc/xpdfrc, if it exists. (This is its default location; depending on build options, it may be placed elsewhere.) On Win32 systems, the xpdfrc file should be placed in the same directory as the executables. The xpdfrc file consists of a series of configuration options, one per line. Blank lines and lines starting with a '#' (comments) are ignored. The following sections list all of the configuration options, sorted into functional groups. There is an examples section at the end. INCLUDE FILES include config-file Includes the specified config file. The effect of this is equivalent to inserting the contents of config-file directly into the parent config file in place of the include command. Config files can be nested arbitrarily deeply. CHARACTER MAPPING nameToUnicode map-file Specifies a file with the mapping from character names to Uni- code. This is used to handle PDF fonts that have valid encod- ings but no ToUnicode entry. Each line of a nameToUnicode file looks like this: hex-string name The hex-string is the Unicode (UCS-2) character index, and name is the corresponding character name. Multiple nameToUnicode files can be used; if a character name is given more than once, the code in the last specified file is used. There is a built- in default nameToUnicode table with all of Adobe's standard character names. cidToUnicode registry-ordering map-file Specifies the file with the mapping from character collection to Unicode. Each line of a cidToUnicode file represents one char- acter: hex-string The hex-string is the Unicode (UCS-2) index for that character. The first line maps CID 0, the second line CID 1, etc. File size is determined by size of the character collection. Only one file is allowed per character collection; the last specified file is used. There are no built-in cidToUnicode mappings. unicodeToUnicode font-name-substring map-file This is used to work around PDF fonts which have incorrect Uni- code information. It specifies a file which maps from the given (incorrect) Unicode indexes to the correct ones. The mapping will be used for any font whose name contains font-name-sub- string. Each line of a unicodeToUnicode file represents one Unicode character: in-hex out-hex1 out-hex2 ... The in-hex field is an input (incorrect) Unicode index, and the rest of the fields are one or more output (correct) Unicode indexes. Each occurrence of in-hex will be converted to the specified output sequence. unicodeMap encoding-name map-file Specifies the file with mapping from Unicode to encoding-name. These encodings are used for text output (see below). Each line of a unicodeMap file represents a range of one or more Unicode characters which maps linearly to a range in the output encod- ing: in-start-hex in-end-hex out-start-hex Entries for single characters can be abbreviated to: in-hex out-hex The in-start-hex and in-end-hex fields (or the single in-hex field) specify the Unicode range. The out-start-hex field (or the out-hex field) specifies the start of the output encoding range. The length of the out-start-hex (or out-hex) string determines the length of the output characters (e.g., UTF-8 uses different numbers of bytes to represent characters in different ranges). Entries must be given in increasing Unicode order. Only one file is allowed per encoding; the last specified file is used. The Latin1, ASCII7, Symbol, ZapfDingbats, UTF-8, and UCS-2 encodings are predefined. cMapDir registry-ordering dir Specifies a search directory, dir, for CMaps for the reg- istry-ordering character collection. There can be multiple directories for a particular collection. There are no default CMap directories. toUnicodeDir dir Specifies a search directory, dir, for ToUnicode CMaps. There can be multiple ToUnicode directories. There are no default ToUnicode directories. GENERAL FONT CONFIGURATION fontFile PDF-font-name font-file Maps a PDF font, PDF-font-name, to a font for display or Post- Script output. The font file, font-file, can be any type allowed in a PDF file. This command can be used for 8-bit or 16-bit (CID) fonts. fontDir dir Specifies a search directory for font files. There can be mul- tiple fontDir commands; all of the specified directories will be searched in order. The font files can be Type 1 (.pfa or .pfb) or TrueType (.ttf or .ttc); other files in the directory will be ignored. The font file name (not including the extension) must exactly match the PDF font name. This search is performed if the font name doesn't match any of the fonts declared with the fontFile command. There are no default fontDir directories. fontFileCC registry-ordering font-file Maps the registry-ordering character collection to a font for display or PostScript output. This mapping is used if the font name doesn't match any of the fonts declared with the fontFile, fontDir, psResidentFont16, or psResidentFontCC commands. POSTSCRIPT FONT CONFIGURATION psFontPassthrough yes | no If set to "yes", pass 8-bit font names through to the PostScript output without substitution. Fonts which are not embedded in the PDF file are expected to be available on the printer. This defaults to "no". psResidentFont PDF-font-name PS-font-name When the 8-bit font PDF-font-name is used (without embedding) in a PDF file, it will be translated to the PostScript font PS-font-name, which is assumed to be resident in the printer. Typically, PDF-font-name and PS-font-name are the same. By default, only the Base-14 fonts are assumed to be resident. psResidentFont16 PDF-font-name wMode PS-font-name encoding When the 16-bit (CID) font PDF-font-name with writing mode wMode is used (without embedding) in a PDF file, it will be translated to the PostScript font PS-font-name, which is assumbed to be resident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the specified encoding (which must have been defined with the unicodeMap command). psResidentFontCC registry-ordering wMode PS-font-name encoding When a 16-bit (CID) font using the registry-ordering character collection and wMode writing mode is used (without embedding) in a PDF file, the PostScript font, PS-font-name, is substituted for it. The substituted font is assumbed to be resident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the spec- ified encoding (which must have been defined with the unicodeMap command). psEmbedType1Fonts yes | no If set to "no", prevents embedding of Type 1 fonts in generated PostScript. This defaults to "yes". psEmbedTrueTypeFonts yes | no If set to "no", prevents embedding of TrueType fonts in gener- ated PostScript. This defaults to "yes". psEmbedCIDTrueTypeFonts yes | no If set to "no", prevents embedding of CID TrueType fonts in gen- erated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". psEmbedCIDPostScriptFonts yes | no If set to "no", prevents embedding of CID PostScript fonts in generated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". POSTSCRIPT CONTROL psPaperSize width(pts) height(pts) Sets the paper size for PostScript output. The width and height parameters give the paper size in PostScript points (1 point = 1/72 inch). psPaperSize letter | legal | A4 | A3 | match Sets the paper size for PostScript output to a standard size. The default paper size is set when xpdf and pdftops are built, typically to "letter" or "A4". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. psImageableArea llx lly urx ury Sets the imageable area for PostScript output. The four inte- gers are the coordinates of the lower-left and upper-right cor- ners of the imageable region, specified in points (with the ori- gin being the lower-left corner of the paper). This defaults to the full paper size; the psPaperSize option will reset the imageable area coordinates. psCrop yes | no If set to "yes", PostScript output is cropped to the CropBox specified in the PDF file; otherwise no cropping is done. This defaults to "yes". psExpandSmaller yes | no If set to "yes", PDF pages smaller than the PostScript imageable area are expanded to fill the imageable area. Otherwise, no scalling is done on smaller pages. This defaults to "no". psShrinkLarger yes | no If set to yes, PDF pages larger than the PostScript imageable area are shrunk to fit the imageable area. Otherwise, no scal- ing is done on larger pages. This defaults to "yes". psCenter yes | no If set to yes, PDF pages smaller than the PostScript imageable area (after any scaling) are centered in the imageable area. Otherwise, they are aligned at the lower-left corner of the imageable area. This defaults to "yes". psDuplex yes | no If set to "yes", the generated PostScript will set the "Duplex" pagedevice entry. This tells duplex-capable printers to enable duplexing. This defaults to "no". psLevel level1 | level1sep | level2 | level2sep | level3 | level3Sep Sets the PostScript level to generate. This defaults to "level2". psPreload yes | no If set to "yes", PDF forms are converted to PS procedures, and image data is preloaded. This uses more memory in the Post- Script interpreter, but generates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. This defaults to "no". psOPI yes | no If set to "yes", generates PostScript OPI comments for all images and forms which have OPI information. This option is only available if the Xpdf tools were compiled with OPI support. This defaults to "no". psASCIIHex yes | no If set to "yes", the ASCIIHexEncode filter will be used instead of ASCII85Encode for binary data. This defaults to "no". psUncompressPreloadedImages yes | no If set to "yes", all preloaded images in PS files will uncom- pressed. If set to "no", the original compressed images will be used when possible. The "yes" setting is useful to work around certain buggy PostScript interpreters. This defaults to "no". psRasterResolution float Set the resolution (in dpi) for rasterized pages in PostScript output. (Pdftops will rasterize pages which use transparency.) This defaults to 300. psRasterMono yes | no If set to "yes", rasterized pages in PS files will be monochrome (8-bit gray) instead of color. This defaults to "no". psAlwaysRasterize yes | no If set to "yes", all PostScript output will be rasterized. This defaults to "no". psFile file-or-command Sets the default PostScript file or print command for xpdf. Commands start with a '|' character; anything else is a file. If the file name or command contains spaces it must be quoted. This defaults to unset, which tells xpdf to generate a name of the form .ps for a PDF file .pdf. fontDir dir See the description above, in the DISPLAY FONTS section. TEXT CONTROL textEncoding encoding-name Sets the encoding to use for text output. (This can be overrid- den with the "-enc" switch on the command line.) The encod- ing-name must be defined with the unicodeMap command (see above). This defaults to "Latin1". textEOL unix | dos | mac Sets the end-of-line convention to use for text output. The options are: unix = LF dos = CR+LF mac = CR (This can be overridden with the "-eol" switch on the command line.) The default value is based on the OS where xpdf and pdftotext were built. textPageBreaks yes | no If set to "yes", text extraction will insert page breaks (form feed characters) between pages. This defaults to "yes". textKeepTinyChars yes | no If set to "yes", text extraction will keep all characters. If set to "no", text extraction will discard tiny (smaller than 3 point) characters after the first 50000 per page, avoiding extremely slow run times for PDF files that use special fonts to do shading or cross-hatching. This defaults to "no". MISCELLANEOUS SETTINGS initialZoom percentage | page | width Sets the initial zoom factor. A number specifies a zoom per- centage, where 100 means 72 dpi. You may also specify 'page', to fit the page to the window size, or 'width', to fit the page width to the window width. continuousView yes | no If set to "yes", xpdf will start in continuous view mode, i.e., with one vertical screoll bar for the whole document. This defaults to "no". enableT1lib yes | no Enables or disables use of t1lib (a Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with t1lib support. ("enableT1lib" replaces the old "t1libControl" option.) This option defaults to "yes". enableFreeType yes | no Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". enableFreeType yes | no Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". disableFreeTypeHinting yes | no If this is set to "yes", FreeType hinting will be forced off. This option defaults to "no". antialias yes | no Enables or disables font anti-aliasing in the PDF rasterizer. This option affects all font rasterizers. ("antialias" replaces the anti-aliasing control provided by the old "t1libControl" and "freetypeControl" options.) This default to "yes". vectorAntialias yes | no Enables or disables anti-aliasing of vector graphics in the PDF rasterizer. This defaults to "yes". antialiasPrinting yes | no If this is "yes", bitmaps sent to the printer will be antialiased (according to the "antialias" and "vectorAntialias" settings). If this is "no", printed bitmaps will not be antialiased. This defaults to "no". strokeAdjust yes | no Enables or disables stroke adjustment. Stroke adjustment moves horizontal and vertical lines by up to half a pixel to make them look "cleaner" when vector anti-aliasing is enabled. This defaults to "yes". screenType dispersed | clustered | stochasticClustered Sets the halftone screen type, which will be used when generat- ing a monochrome (1-bit) bitmap. The three options are dis- persed-dot dithering, clustered-dot dithering (with a round dot and 45-degree screen angle), and stochastic clustered-dot dithering. By default, "stochasticClustered" is used for reso- lutions of 300 dpi and higher, and "dispersed" is used for reso- lutions lower then 300 dpi. screenSize integer Sets the size of the (square) halftone screen threshold matrix. By default, this is 4 for dispersed-dot dithering, 10 for clus- tered-dot dithering, and 100 for stochastic clustered-dot dithering. screenDotRadius integer Sets the halftone screen dot radius. This is only used when screenType is set to stochasticClustered, and it defaults to 2. In clustered-dot mode, the dot radius is half of the screen size. Dispersed-dot dithering doesn't have a dot radius. screenGamma float Sets the halftone screen gamma correction parameter. Gamma val- ues greater than 1 make the output brighter; gamma values less than 1 make it darker. The default value is 1. screenBlackThreshold float When halftoning, all values below this threshold are forced to solid black. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 0. screenWhiteThreshold float When halftoning, all values above this threshold are forced to solid white. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 1. minLineWidth float Set the minimum line width, in device pixels. This affects the rasterizer only, not the PostScript converter (except when it uses rasterization to handle transparency). The default value is 0 (no minimum). drawAnnotations yes | no If set to "no", annotations will not be drawn or printed. The default value is "yes". overprintPreview yes | no If set to "yes", generate overprint preview output, honoring the OP/op/OPM settings in the PDF file. Ignored for non-CMYK out- put. The default value is "no". launchCommand command Sets the command executed when you click on a "launch"-type link. The intent is for the command to be a program/script which determines the file type and runs the appropriate viewer. The command line will consist of the file to be launched, fol- lowed by any parameters specified with the link. Do not use "%s" in "command". By default, this is unset, and Xpdf will simply try to execute the file (after prompting the user). urlCommand command Sets the command executed when you click on a URL link. The string "%s" will be replaced with the URL. (See the example below.) This has no default value. movieCommand command Sets the command executed when you click on a movie annotation. The string "%s" will be replaced with the movie file name. This has no default value. mapNumericCharNames yes | no If set to "yes", the Xpdf tools will attempt to map various numeric character names sometimes used in font subsets. In some cases this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "yes". mapUnknownCharNames yes | no If set to "yes", and mapNumericCharNames is set to "no", the Xpdf tools will apply a simple pass-through mapping (Unicode index = character code) for all unrecognized glyph names. (For CID fonts, setting mapNumericCharNames to "no" is unnecessary.) In some cases, this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "no". bind modifiers-key context command ... Add a key or mouse button binding. Modifiers can be zero or more of: shift- ctrl- alt- Key can be a regular ASCII character, or any one of: space tab return enter backspace insert delete home end pgup pgdn left / right / up / down (arrow keys) f1 .. f35 (function keys) mousePress1 .. mousePress7 (mouse buttons) mouseRelease1 .. mouseRelease7 (mouse buttons) Context is either "any" or a comma-separated combination of: fullScreen / window (full screen mode on/off) continuous / singlePage (continuous mode on/off) overLink / offLink (mouse over link or not) scrLockOn / scrLockOff (scroll lock on/off) The context string can include only one of each pair in the above list. Command is an Xpdf command (see the COMMANDS section of the xpdf(1) man page for details). Multiple commands are separated by whitespace. The bind command replaces any existing binding, but only if it was defined for the exact same modifiers, key, and context. All tokens (modifiers, key, context, commands) are case-sensitive. Example key bindings: # bind ctrl-a in any context to the nextPage # command bind ctrl-a any nextPage # bind uppercase B, when in continuous mode # with scroll lock on, to the reload command # followed by the prevPage command bind B continuous,scrLockOn reload prevPage See the xpdf(1) man page for more examples. unbind modifiers-key context Removes a key binding established with the bind command. This is most useful to remove default key bindings before establish- ing new ones (e.g., if the default key binding is given for "any" context, and you want to create new key bindings for mul- tiple contexts). printCommands yes | no If set to "yes", drawing commands are printed as they're exe- cuted (useful for debugging). This defaults to "no". errQuiet yes | no If set to "yes", this suppresses all error and warning messages from all of the Xpdf tools. This defaults to "no".

Pdftops reads the PDF file, PDF-file, and writes a PostScript file, PS- file. If PS-file is not specified, pdftops converts file.pdf to file.ps (or file.eps with the -eps option). If PS-file is '-', the PostScript is sent to stdout. () 2 ONFIGURATION_FIL Pdftops reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftops is built). See the xpdfrc(5) man page for details. () 2 OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to print. -l number Specifies the last page to print. -level1 Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. No more than one of the PostScript level options (-level1, -level1sep, -level2, -level2sep, -level3, -level3Sep) may be given. [config file: psLevel] -level1sep Generate Level 1 separable PostScript. All colors are converted to CMYK. Images are written with separate stream data for the four components. [config file: psLevel] -level2 Generate Level 2 PostScript. Level 2 supports color images and image compression. This is the default setting. [config file: psLevel] -level2sep Generate Level 2 separable PostScript. All colors are converted to CMYK. The PostScript separation convention operators are used to handle custom (spot) colors. [config file: psLevel] -level3 Generate Level 3 PostScript. This enables all Level 2 features plus CID font embedding and masked image generation. [config file: psLevel] -level3Sep Generate Level 3 separable PostScript. The separation handling is the same as for -level2Sep. [config file: psLevel] -eps Generate an Encapsulated PostScript (EPS) file. An EPS file contains a single image, so if you use this option with a multi- page PDF file, you must use -f and -l to specify a single page. No more than one of the mode options (-eps, -form) may be given. -form Generate a PostScript form which can be imported by software that understands forms. A form contains a single page, so if you use this option with a multi-page PDF file, you must use -f and -l to specify a single page. The -level1 option cannot be used with -form. -opi Generate OPI comments for all images and forms which have OPI information. (This option is only available if pdftops was com- piled with OPI support.) [config file: psOPI] -noembt1 By default, any Type 1 fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make Post- Script files larger, but may be necessary for readable output. [config file: psEmbedType1Fonts] -noembtt By default, any TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option causes pdftops to substitute base fonts instead. Embedded fonts make PostScript files larger, but may be necessary for readable out- put. Also, some PostScript interpreters do not have TrueType rasterizers. [config file: psEmbedTrueTypeFonts] -noembcidps By default, any CID PostScript fonts which are embedded in the PDF file are copied into the PostScript file. This option dis- ables that embedding. No attempt is made to substitute for non- embedded CID PostScript fonts. [config file: psEmbedCID- PostScriptFonts] -noembcidtt By default, any CID TrueType fonts which are embedded in the PDF file are copied into the PostScript file. This option disables that embedding. No attempt is made to substitute for non-embed- ded CID TrueType fonts. [config file: psEmbedCIDTrueTypeFonts] -preload Convert PDF forms to PS procedures, and preload image data. This uses more memory in the PostScript interpreter, but gener- ates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. -paper size Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. [config file: psPaperSize] -paperw size Set the paper width, in points. [config file: psPaperSize] -paperh size Set the paper height, in points. [config file: psPaperSize] -nocrop By default, output is cropped to the CropBox specified in the PDF file. This option disables cropping. [config file: psCrop] -expand Expand PDF pages smaller than the paper to fill the paper. By default, these pages are not scaled. [config file: psExpandS- maller] -noshrink Don't scale PDF pages which are larger than the paper. By default, pages larger than the paper are shrunk to fit. [config file: psShrinkLarger] -nocenter By default, PDF pages smaller than the paper (after any scaling) are centered on the paper. This option causes them to be aligned to the lower-left corner of the paper instead. [config file: psCenter] -pagecrop Treat the CropBox as the PDF page size. By default, the Media- Box is used as the page size. -duplex Set the Duplex pagedevice entry in the PostScript file. This tells duplex-capable printers to enable duplexing. [config file: psDuplex] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. [config file: errQuiet] -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.)

If you have a .I .xpdfrc file in your home directory, it will be read. Otherwise, a system-wide configuration file will be read from .IR /usr/local/etc/xpdfrc , if it exists. (This is its default location; depending on build options, it may be placed elsewhere.) On Win32 systems, the .I xpdfrc file should be placed in the same directory as the executables. .PP The xpdfrc file consists of a series of configuration options, one per line. Blank lines and lines starting with a \'#' (comments) are ignored. .PP The following sections list all of the configuration options, sorted into functional groups. There is an examples section at the end. .SH INCLUDE FILES .TP .BI include " config\-file" Includes the specified config file. The effect of this is equivalent to inserting the contents of .I config\-file directly into the parent config file in place of the .I include command. Config files can be nested arbitrarily deeply. .SH CHARACTER MAPPING .TP .BI nameToUnicode " map\-file" Specifies a file with the mapping from character names to Unicode. This is used to handle PDF fonts that have valid encodings but no ToUnicode entry. Each line of a nameToUnicode file looks like this: .I " " hex\-string name The .I hex\-string is the Unicode (UCS-2) character index, and .I name is the corresponding character name. Multiple nameToUnicode files can be used; if a character name is given more than once, the code in the last specified file is used. There is a built-in default nameToUnicode table with all of Adobe's standard character names. .TP .BI cidToUnicode " registry\-ordering map\-file" Specifies the file with the mapping from character collection to Unicode. Each line of a cidToUnicode file represents one character: .I " " hex\-string The .I hex\-string is the Unicode (UCS-2) index for that character. The first line maps CID 0, the second line CID 1, etc. File size is determined by size of the character collection. Only one file is allowed per character collection; the last specified file is used. There are no built-in cidToUnicode mappings. .TP .BI unicodeToUnicode " font\-name\-substring map\-file" This is used to work around PDF fonts which have incorrect Unicode information. It specifies a file which maps from the given (incorrect) Unicode indexes to the correct ones. The mapping will be used for any font whose name contains .IR font\-name\-substring . Each line of a unicodeToUnicode file represents one Unicode character: .RI " " in\-hex " " out\-hex1 " " out\-hex2 " ..." The .I in\-hex field is an input (incorrect) Unicode index, and the rest of the fields are one or more output (correct) Unicode indexes. Each occurrence of .I in\-hex will be converted to the specified output sequence. .TP .BI unicodeMap " encoding\-name map\-file" Specifies the file with mapping from Unicode to .IR encoding\-name . These encodings are used for text output (see below). Each line of a unicodeMap file represents a range of one or more Unicode characters which maps linearly to a range in the output encoding: .nf .I " " in\-start\-hex in\-end\-hex out\-start\-hex .fi Entries for single characters can be abbreviated to: .nf .I " " in\-hex out\-hex .fi The .I in\-start\-hex and .I in\-end\-hex fields (or the single .I in\-hex field) specify the Unicode range. The .I out\-start\-hex field (or the .I out\-hex field) specifies the start of the output encoding range. The length of the .I out\-start\-hex (or .IR out\-hex ) string determines the length of the output characters (e.g., UTF-8 uses different numbers of bytes to represent characters in different ranges). Entries must be given in increasing Unicode order. Only one file is allowed per encoding; the last specified file is used. The .IR Latin1 , .IR ASCII7 , .IR Symbol , .IR ZapfDingbats , .IR UTF-8 , and .I UCS-2 encodings are predefined. .TP .BI cMapDir " registry\-ordering dir" Specifies a search directory, .IR dir , for CMaps for the .I registry\-ordering character collection. There can be multiple directories for a particular collection. There are no default CMap directories. .TP .BI toUnicodeDir " dir" Specifies a search directory, .IR dir , for ToUnicode CMaps. There can be multiple ToUnicode directories. There are no default ToUnicode directories. .SH GENERAL FONT CONFIGURATION .TP .BI fontFile " PDF\-font\-name font\-file" Maps a PDF font, .IR PDF\-font\-name , to a font for display or PostScript output. The font file, .IR font\-file , can be any type allowed in a PDF file. This command can be used for 8-bit or 16-bit (CID) fonts. .TP .BI fontDir " dir" Specifies a search directory for font files. There can be multiple fontDir commands; all of the specified directories will be searched in order. The font files can be Type 1 (.pfa or .pfb) or TrueType (.ttf or .ttc); other files in the directory will be ignored. The font file name (not including the extension) must exactly match the PDF font name. This search is performed if the font name doesn't match any of the fonts declared with the fontFile command. There are no default fontDir directories. .TP .BI fontFileCC " registry\-ordering font\-file" Maps the .I registry\-ordering character collection to a font for display or PostScript output. This mapping is used if the font name doesn't match any of the fonts declared with the fontFile, fontDir, psResidentFont16, or psResidentFontCC commands. .SH POSTSCRIPT FONT CONFIGURATION .TP .BR psFontPassthrough " yes | no" If set to "yes", pass 8-bit font names through to the PostScript output without substitution. Fonts which are not embedded in the PDF file are expected to be available on the printer. This defaults to "no". .TP .BI psResidentFont " PDF\-font\-name PS\-font\-name" When the 8-bit font .I PDF\-font\-name is used (without embedding) in a PDF file, it will be translated to the PostScript font .IR PS\-font\-name , which is assumed to be resident in the printer. Typically, .I PDF\-font\-name and .I PS\-font\-name are the same. By default, only the Base-14 fonts are assumed to be resident. .TP .BI psResidentFont16 " PDF\-font\-name wMode PS\-font\-name encoding" When the 16-bit (CID) font .I PDF\-font\-name with writing mode .I wMode is used (without embedding) in a PDF file, it will be translated to the PostScript font .IR PS\-font\-name , which is assumbed to be resident in the printer. The writing mode must be either \'H' for horizontal or \'V' for vertical. The resident font is assumed to use the specified encoding (which must have been defined with the unicodeMap command). .TP .BI psResidentFontCC " registry\-ordering wMode PS\-font\-name encoding" When a 16-bit (CID) font using the .I registry\-ordering character collection and .I wMode writing mode is used (without embedding) in a PDF file, the PostScript font, .IR PS\-font\-name , is substituted for it. The substituted font is assumbed to be resident in the printer. The writing mode must be either \'H' for horizontal or \'V' for vertical. The resident font is assumed to use the specified encoding (which must have been defined with the unicodeMap command). .TP .BR psEmbedType1Fonts " yes | no" If set to "no", prevents embedding of Type 1 fonts in generated PostScript. This defaults to "yes". .TP .BR psEmbedTrueTypeFonts " yes | no" If set to "no", prevents embedding of TrueType fonts in generated PostScript. This defaults to "yes". .TP .BR psEmbedCIDTrueTypeFonts " yes | no" If set to "no", prevents embedding of CID TrueType fonts in generated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". .TP .BR psEmbedCIDPostScriptFonts " yes | no" If set to "no", prevents embedding of CID PostScript fonts in generated PostScript. For Level 3 PostScript, this generates a CID font, for lower levels it generates a non-CID composite font. This defaults to "yes". .SH POSTSCRIPT CONTROL .TP .BI psPaperSize " width(pts) height(pts)" Sets the paper size for PostScript output. The .I width and .I height parameters give the paper size in PostScript points (1 point = 1/72 inch). .TP .BR psPaperSize " letter | legal | A4 | A3 | match" Sets the paper size for PostScript output to a standard size. The default paper size is set when xpdf and pdftops are built, typically to "letter" or "A4". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. .TP .BR psImageableArea " llx lly urx ury" Sets the imageable area for PostScript output. The four integers are the coordinates of the lower-left and upper-right corners of the imageable region, specified in points (with the origin being the lower-left corner of the paper). This defaults to the full paper size; the psPaperSize option will reset the imageable area coordinates. .TP .BR psCrop " yes | no" If set to "yes", PostScript output is cropped to the CropBox specified in the PDF file; otherwise no cropping is done. This defaults to "yes". .TP .BR psExpandSmaller " yes | no" If set to "yes", PDF pages smaller than the PostScript imageable area are expanded to fill the imageable area. Otherwise, no scalling is done on smaller pages. This defaults to "no". .TP .BR psShrinkLarger " yes | no" If set to yes, PDF pages larger than the PostScript imageable area are shrunk to fit the imageable area. Otherwise, no scaling is done on larger pages. This defaults to "yes". .TP .BR psCenter " yes | no" If set to yes, PDF pages smaller than the PostScript imageable area (after any scaling) are centered in the imageable area. Otherwise, they are aligned at the lower-left corner of the imageable area. This defaults to "yes". .TP .BR psDuplex " yes | no" If set to "yes", the generated PostScript will set the "Duplex" pagedevice entry. This tells duplex-capable printers to enable duplexing. This defaults to "no". .TP .BR psLevel " level1 | level1sep | level2 | level2sep | level3 | level3Sep" Sets the PostScript level to generate. This defaults to "level2". .TP .BR psPreload " yes | no" If set to "yes", PDF forms are converted to PS procedures, and image data is preloaded. This uses more memory in the PostScript interpreter, but generates significantly smaller PS files in situations where, e.g., the same image is drawn on every page of a long document. This defaults to "no". .TP .BR psOPI " yes | no" If set to "yes", generates PostScript OPI comments for all images and forms which have OPI information. This option is only available if the Xpdf tools were compiled with OPI support. This defaults to "no". .TP .BR psASCIIHex " yes | no" If set to "yes", the ASCIIHexEncode filter will be used instead of ASCII85Encode for binary data. This defaults to "no". .TP .BR psUncompressPreloadedImages " yes | no" If set to "yes", all preloaded images in PS files will uncompressed. If set to "no", the original compressed images will be used when possible. The "yes" setting is useful to work around certain buggy PostScript interpreters. This defaults to "no". .TP .BR psRasterResolution " float" Set the resolution (in dpi) for rasterized pages in PostScript output. (Pdftops will rasterize pages which use transparency.) This defaults to 300. .TP .BR psRasterMono " yes | no" If set to "yes", rasterized pages in PS files will be monochrome (8-bit gray) instead of color. This defaults to "no". .TP .BR psAlwaysRasterize " yes | no" If set to "yes", all PostScript output will be rasterized. This defaults to "no". .TP .BI psFile " file\-or\-command" Sets the default PostScript file or print command for xpdf. Commands start with a \'|' character; anything else is a file. If the file name or command contains spaces it must be quoted. This defaults to unset, which tells xpdf to generate a name of the form .ps for a PDF file .pdf. .TP .BI fontDir " dir" See the description above, in the DISPLAY FONTS section. .SH TEXT CONTROL .TP .BI textEncoding " encoding\-name" Sets the encoding to use for text output. (This can be overridden with the "\-enc" switch on the command line.) The .I encoding\-name must be defined with the unicodeMap command (see above). This defaults to "Latin1". .TP .BR textEOL " unix | dos | mac" Sets the end-of-line convention to use for text output. The options are: .nf unix = LF dos = CR+LF mac = CR .fi (This can be overridden with the "\-eol" switch on the command line.) The default value is based on the OS where xpdf and pdftotext were built. .TP .BR textPageBreaks " yes | no" If set to "yes", text extraction will insert page breaks (form feed characters) between pages. This defaults to "yes". .TP .BR textKeepTinyChars " yes | no" If set to "yes", text extraction will keep all characters. If set to "no", text extraction will discard tiny (smaller than 3 point) characters after the first 50000 per page, avoiding extremely slow run times for PDF files that use special fonts to do shading or cross-hatching. This defaults to "no". .SH MISCELLANEOUS SETTINGS .TP .BR initialZoom " \fIpercentage\fR | page | width" Sets the initial zoom factor. A number specifies a zoom percentage, where 100 means 72 dpi. You may also specify \'page', to fit the page to the window size, or \'width', to fit the page width to the window width. .TP .BR continuousView " yes | no" If set to "yes", xpdf will start in continuous view mode, i.e., with one vertical screoll bar for the whole document. This defaults to "no". .TP .BR enableT1lib " yes | no" Enables or disables use of t1lib (a Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with t1lib support. ("enableT1lib" replaces the old "t1libControl" option.) This option defaults to "yes". .TP .BR enableFreeType " yes | no" Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". .TP .BR enableFreeType " yes | no" Enables or disables use of FreeType (a TrueType / Type 1 font rasterizer). This is only relevant if the Xpdf tools were built with FreeType support. ("enableFreeType" replaces the old "freetypeControl" option.) This option defaults to "yes". .TP .BR disableFreeTypeHinting " yes | no" If this is set to "yes", FreeType hinting will be forced off. This option defaults to "no". .TP .BR antialias " yes | no" Enables or disables font anti-aliasing in the PDF rasterizer. This option affects all font rasterizers. ("antialias" replaces the anti-aliasing control provided by the old "t1libControl" and "freetypeControl" options.) This default to "yes". .TP .BR vectorAntialias " yes | no" Enables or disables anti-aliasing of vector graphics in the PDF rasterizer. This defaults to "yes". .TP .BR antialiasPrinting " yes | no" If this is "yes", bitmaps sent to the printer will be antialiased (according to the "antialias" and "vectorAntialias" settings). If this is "no", printed bitmaps will not be antialiased. This defaults to "no". .TP .BR strokeAdjust " yes | no" Enables or disables stroke adjustment. Stroke adjustment moves horizontal and vertical lines by up to half a pixel to make them look "cleaner" when vector anti-aliasing is enabled. This defaults to "yes". .TP .BR screenType " dispersed | clustered | stochasticClustered" Sets the halftone screen type, which will be used when generating a monochrome (1-bit) bitmap. The three options are dispersed-dot dithering, clustered-dot dithering (with a round dot and 45-degree screen angle), and stochastic clustered-dot dithering. By default, "stochasticClustered" is used for resolutions of 300 dpi and higher, and "dispersed" is used for resolutions lower then 300 dpi. .TP .BI screenSize " integer" Sets the size of the (square) halftone screen threshold matrix. By default, this is 4 for dispersed-dot dithering, 10 for clustered-dot dithering, and 100 for stochastic clustered-dot dithering. .TP .BI screenDotRadius " integer" Sets the halftone screen dot radius. This is only used when screenType is set to stochasticClustered, and it defaults to 2. In clustered-dot mode, the dot radius is half of the screen size. Dispersed-dot dithering doesn't have a dot radius. .TP .BI screenGamma " float" Sets the halftone screen gamma correction parameter. Gamma values greater than 1 make the output brighter; gamma values less than 1 make it darker. The default value is 1. .TP .BI screenBlackThreshold " float" When halftoning, all values below this threshold are forced to solid black. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 0. .TP .BI screenWhiteThreshold " float" When halftoning, all values above this threshold are forced to solid white. This parameter is a floating point value between 0 (black) and 1 (white). The default value is 1. .TP .BI minLineWidth " float" Set the minimum line width, in device pixels. This affects the rasterizer only, not the PostScript converter (except when it uses rasterization to handle transparency). The default value is 0 (no minimum). .TP .BI drawAnnotations " yes | no" If set to "no", annotations will not be drawn or printed. The default value is "yes". .TP .BI overprintPreview " yes | no" If set to "yes", generate overprint preview output, honoring the OP/op/OPM settings in the PDF file. Ignored for non-CMYK output. The default value is "no". .TP .BI launchCommand " command" Sets the command executed when you click on a "launch"-type link. The intent is for the command to be a program/script which determines the file type and runs the appropriate viewer. The command line will consist of the file to be launched, followed by any parameters specified with the link. Do not use "%s" in "command". By default, this is unset, and Xpdf will simply try to execute the file (after prompting the user). .TP .BI urlCommand " command" Sets the command executed when you click on a URL link. The string "%s" will be replaced with the URL. (See the example below.) This has no default value. .TP .BI movieCommand " command" Sets the command executed when you click on a movie annotation. The string "%s" will be replaced with the movie file name. This has no default value. .TP .BI mapNumericCharNames " yes | no" If set to "yes", the Xpdf tools will attempt to map various numeric character names sometimes used in font subsets. In some cases this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "yes". .TP .BI mapUnknownCharNames " yes | no" If set to "yes", and mapNumericCharNames is set to "no", the Xpdf tools will apply a simple pass-through mapping (Unicode index = character code) for all unrecognized glyph names. (For CID fonts, setting mapNumericCharNames to "no" is unnecessary.) In some cases, this leads to usable text, and in other cases it leads to gibberish -- there is no way for Xpdf to tell. This defaults to "no". .TP .BI bind " modifiers-key context command ..." Add a key or mouse button binding. .I Modifiers can be zero or more of: .nf shift- ctrl- alt- .fi .I Key can be a regular ASCII character, or any one of: .nf space tab return enter backspace insert delete home end pgup pgdn left / right / up / down (arrow keys) f1 .. f35 (function keys) mousePress1 .. mousePress7 (mouse buttons) mouseRelease1 .. mouseRelease7 (mouse buttons) .fi .I Context is either "any" or a comma-separated combination of: .nf fullScreen / window (full screen mode on/off) continuous / singlePage (continuous mode on/off) overLink / offLink (mouse over link or not) scrLockOn / scrLockOff (scroll lock on/off) .fi The context string can include only one of each pair in the above list. .I Command is an Xpdf command (see the COMMANDS section of the .BR xpdf (1) man page for details). Multiple commands are separated by whitespace. The bind command replaces any existing binding, but only if it was defined for the exact same modifiers, key, and context. All tokens (modifiers, key, context, commands) are case-sensitive. Example key bindings: .nf # bind ctrl-a in any context to the nextPage # command bind ctrl-a any nextPage # bind uppercase B, when in continuous mode # with scroll lock on, to the reload command # followed by the prevPage command bind B continuous,scrLockOn reload prevPage .fi See the .BR xpdf (1) man page for more examples. .TP .BI unbind " modifiers-key context" Removes a key binding established with the bind command. This is most useful to remove default key bindings before establishing new ones (e.g., if the default key binding is given for "any" context, and you want to create new key bindings for multiple contexts). .TP .BI printCommands " yes | no" If set to "yes", drawing commands are printed as they're executed (useful for debugging). This defaults to "no". .TP .BI errQuiet " yes | no" If set to "yes", this suppresses all error and warning messages from all of the Xpdf tools. This defaults to "no". .SH EXAMPLES The following is a sample xpdfrc file. .nf # from the Thai support package nameToUnicode /usr/local/share/xpdf/Thai.nameToUnicode # from the Japanese support package cidToUnicode Adobe-Japan1 /usr/local/share/xpdf/Adobe-Japan1.cidToUnicode unicodeMap JISX0208 /usr/local/share/xpdf/JISX0208.unicodeMap cMapDir Adobe-Japan1 /usr/local/share/xpdf/cmap/Adobe-Japan1 # use the Base-14 Type 1 fonts from ghostscript fontFile Times-Roman /usr/local/share/ghostscript/fonts/n021003l.pfb fontFile Times-Italic /usr/local/share/ghostscript/fonts/n021023l.pfb fontFile Times-Bold /usr/local/share/ghostscript/fonts/n021004l.pfb fontFile Times-BoldItalic /usr/local/share/ghostscript/fonts/n021024l.pfb fontFile Helvetica /usr/local/share/ghostscript/fonts/n019003l.pfb fontFile Helvetica-Oblique /usr/local/share/ghostscript/fonts/n019023l.pfb fontFile Helvetica-Bold /usr/local/share/ghostscript/fonts/n019004l.pfb fontFile Helvetica-BoldOblique /usr/local/share/ghostscript/fonts/n019024l.pfb fontFile Courier /usr/local/share/ghostscript/fonts/n022003l.pfb fontFile Courier-Oblique /usr/local/share/ghostscript/fonts/n022023l.pfb fontFile Courier-Bold /usr/local/share/ghostscript/fonts/n022004l.pfb fontFile Courier-BoldOblique /usr/local/share/ghostscript/fonts/n022024l.pfb fontFile Symbol /usr/local/share/ghostscript/fonts/s050000l.pfb fontFile ZapfDingbats /usr/local/share/ghostscript/fonts/d050000l.pfb # use the Bakoma Type 1 fonts # (this assumes they happen to be installed in /usr/local/fonts/bakoma) fontDir /usr/local/fonts/bakoma # set some PostScript options psPaperSize letter psDuplex no psLevel level2 psEmbedType1Fonts yes psEmbedTrueTypeFonts yes psFile "| lpr \-Pprinter5" # assume that the PostScript printer has the Univers and # Univers-Bold fonts psResidentFont Univers Univers psResidentFont Univers-Bold Univers-Bold # set the text output options textEncoding UTF-8 textEOL unix # misc options enableT1lib yes enableFreeType yes launchCommand viewer-script urlCommand "netscape \-remote 'openURL(%s)'" .fi .SH FILES .TP .B /usr/local/etc/xpdfrc This is the default location for the system-wide configuration file.

If .I text-file is not specified, pdftotext converts .I file.pdf to .IR file.txt . If .I text-file is \'-', the text is sent to stdout. .SH CONFIGURATION FILE Pdftotext reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdftotext is built). See the .BR xpdfrc (5) man page for details. .SH OPTIONS Many of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option. .TP .BI \-f " number" Specifies the first page to convert. .TP .BI \-l " number" Specifies the last page to convert. .TP .B \-layout Maintain (as best as possible) the original physical layout of the text. The default is to \'undo' physical layout (columns, hyphenation, etc.) and output the text in reading order. .TP .BI \-fixed " number" Assume fixed-pitch (or tabular) text, with the specified character width (in points). This forces physical layout mode. .TP .B \-raw Keep the text in content stream order. This is a hack which often "undoes" column formatting, etc. Use of raw mode is no longer recommended. .TP .B \-htmlmeta Generate a simple HTML file, including the meta information. This simply wraps the text in 
 and
and prepends the meta headers. .TP .BI \-enc " encoding-name" Sets the encoding to use for text output. The .I encoding\-name must be defined with the unicodeMap command (see .BR xpdfrc (5)). The encoding name is case-sensitive. This defaults to "Latin1" (which is a built-in encoding). .RB "[config file: " textEncoding ] .TP .BI \-eol " unix | dos | mac" Sets the end-of-line convention to use for text output. .RB "[config file: " textEOL ] .TP .B \-nopgbrk Don't insert page breaks (form feed characters) between pages. .RB "[config file: " textPageBreaks ] .TP .BI \-opw " password" Specify the owner password for the PDF file.

Generated automatically by mantohlp 1 pdfinfo pdfinfo - Portable Document Format (PDF) document information pdfinfo [options] [PDF-file] Pdfinfo prints the contents of the 'Info' dictionary (plus some other useful information) from a Portable Document Format (PDF) file. The 'Info' dictionary contains the following values: title subject keywords author creator producer creation date modification date In addition, the following information is printed: tagged (yes/no) form (AcroForm / XFA / none) page count encrypted flag (yes/no) print and copy permissions (if encrypted) page size file size linearized (yes/no) PDF version metadata (only if requested) () 2 ONFIGURATION_FIL Pdfinfo reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdfinfo is built). See the xpdfrc(5) man page for details. () 2 OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to examine. If multiple pages are requested using the "-f" and "-l" options, the size of each requested page (and, optionally, the bounding boxes for each requested page) are printed. Otherwise, only page one is exam- ined. -l number Specifies the last page to examine. -box Prints the page box bounding boxes: MediaBox, CropBox, BleedBox, TrimBox, and ArtBox. -meta Prints document-level metadata. (This is the "Metadata" stream from the PDF file's Catalog object.) -rawdates Prints the raw (undecoded) date strings, directly from the PDF file. -enc encoding-name Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [con- fig file: textEncoding] -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -cfg config-file Read config-file in place of ~/.xpdfrc or the system-wide config file. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.)

Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each page, PPM-root-nnnnnn.ppm, where nnnnnn is the page number. If PPM- root is '-', the image is sent to stdout (this is probably only useful when converting a single page). CONFIGURATION FILE Pdftoppm reads a configuration file at startup.

Pdfimages reads the PDF file, scans one or more pages, PDF-file, and writes one PPM, PBM, or JPEG file for each image, image-root-nnn.xxx, where nnn is the image number and xxx is the image type (.ppm, .pbm, .jpg). NB: pdfimages extracts the raw image data from the PDF file, without performing any additional transforms. Any rotation, clipping, color inversion, etc. done by the PDF content stream is ignored. CONFIGURATION FILE Pdfimages reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdfimages is built). See the xpdfrc(5) man page for details. OPTIONS Many of the following options can be set with configuration file com- mands. These are listed in square brackets with the description of the corresponding command line option. -f number Specifies the first page to scan. -l number Specifies the last page to scan. -j Normally, all images are written as PBM (for monochrome images) or PPM (for non-monochrome images) files. With this option, images in DCT format are saved as JPEG files. All non-DCT images are saved in PBM/PPM format as usual. -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors.
