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.

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 -

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 -

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 -

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.

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 -

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. - -3.04 (2014-may-28) ------------------- -New text extractor. -Added the pdftohtml tool. -Added the pdftopng tool. -New trapezoid-based rasterizer core (for performance). -Generate appearance streams for Line, PolyLine, and Polygon -

addition to strokes and fills). -Decode JPEG 2000 images at less than full resolution if the full res - image isn't needed (i.e., if the raw image is higher resolution than - the output). -Implemented knockout groups. -Removed t1lib support. -Added support for images with 16-bit components. -Rewrote the Dict class to use a hash table; as a side effect, this - handles dictionaries with multiple definitions for a key, which are - in violation of the spec, but Acrobat appears to handle. -The transformed line width computation -- used to implement the - minLineWidth setting, and the hairline threshold in monochrome mode -- - was incorrect. -Pdftops was not correctly handling the case where it couldn't find - a 16-bit font -- this led to crashes and/or invalid PostScript. -A bug in FlateStream::getBlock() was causing problems with narrow - images. -Use the correct _WIN32 define instead of WIN32. -Use copy-on-write for the clip path in SplashState (when doing gsave), - for performance. -Added a Solaris-specific entry to the ghostscript font search path. -SplashState was initializing line width to 0 instead of 1. -Abort processing on a content stream after getting 500 errors - (undefined operator, wrong number of args) -- this avoids very long - processing time for malicious PDF files using bogus RLE encoded - content streams. -Added the psUseCropBoxAsPage xpdfrc option; "pdftops -pagecrop" now - sets psUseCropBoxAsPage; "pdftops -pagecrop -paper match" now uses - the CropBox as the page size. -Re-architected the AcroForm support code into a separate AcroForm - module. -Fixed the handling of overprinting/transparency interaction, using - the CompatibleOverprint blend mode. -The TIFF predictor code for the 1-bit-per-pixel case was broken. -For triangle and patch mesh shadings (types 4-7) with color functions, - interpolate the function parameter not the color. -Check the fontFile/fontDir commands before (instead of after) doing -

TextPage::beginWord was crashing. -The Domain entry in function shadings wasn't being parsed correctly. -Fixed a bug in the JPEG decoder - successive approximation - (progressive mode) coefficients weren't being handled correctly. -Added a better infinite loop test to the xref parser. -When generating PostScript, merge reused TrueType fonts (if their - code-to-GID mappings are the same). -Tweak the Gouraud triangle shaded fill code to end the recursive - splitting if the triangles get sufficiently small. -Do bilinear interpolation when upsampling images. -When skipping extraneous image data from an inline image, look for - EI instead of just EI. -When writing to stdout on Windows, pdftoppm now sets the file mode to - binary.

[Thanks to Nickolai Zeldovich.] -Correctly handle streams with missing Length entries in damaged PDF - files. -Added a compile-time option (LOAD_FONTS_FROM_MEM) to load fonts from - memory rather than temporary files on disk. -Added the psRasterSliceSize xpdfrc option. -Fixed a case in the JPEG 2000 arithmetic decoder where extra data is - present in packet i, and needs to be saved for use in packet i+1. -Fixed a bug in the JPEG 2000 decoder related to images with fewer than - 8 bits per component. -Handle the case in PSOutputDev where slice size overflows a 32-bit - integer. -Add (partial) support for TrueType cmap format 2. -Always pass FT_LOAD_NO_BITMAP to FreeType -- bitmaps apparently fail - with rotated characters. -Support fonts specified in ExtGState dictionaries. -Annotations with empty Border arrays should not draw a border. -Fix the CMap parser to handle large CID ranges. -Check for Type 3 CharProcs that call q or Q before the d0/d1 operator, - and treat them as uncacheable. -Invert the selection color when starting in reverse video mode. -Device{Gray,RGB,CMYK} cannot be mapped via a resource dict. -Changed the PS output for masked images (explicit and color key - masking): use a plain old clip path instead of rectclip to avoid - array overflows. -Check the StemSnapH/V arrays when converting Type 1C fonts to Type 1 - - if there are any duplicate or out-of-order values, skip that - StemSnapH/V array. -Added the psMinLineWidth xpdfrc setting. -Fix an obscure issue in converting TrueType fonts to Type 42, related - to empty glyph descriptions (12 zero bytes). -Pdftops now reports an error if there were any I/O errors writing to - the PS output file. -Fix vertical text (CJK fonts) in PS output -- offset the character - origin correctly. -Increased the number of digits used by pdfimages for the image number - from three to four. -Handle right-to-left (e.g., Arabic) ligatures correctly in the text - extractor. -Added the -loc and -locPS options to pdffonts. -Extend the object parser recursion limit to cover Stream::addFilters() - / Stream::makeFilters() - to avoid another possibility of stack - overflow. -Disable FreeType autohinting, because it can fail badly with font - subsets that use invalid glyph names -- except in the case of Type 1 - fonts, which look much better with light autohinting. -Modified the rasterizer pipeline functions to process a scan line at a - time (for performance). -Removed VMS build support (it hasn't been updated in ages). -Removed pdftotext's '-htmlmeta' option (use pdftohtml instead). -PSOutputDev's font/form setup code, and pdffonts, were not scanning - soft mask groups in ExtGState dictionaries. -Invalid DCT input (e.g., from a damaged PDF file) could overflow the - dctClip array. -When upsampling an image mask or image with a large resulting image - size, do it in stream mode instead of prescaling the whole image - (to avoid running out of memory). -Added infinite loop detection to pdffonts. diff --git a/Build/source/libs/xpdf/xpdf-3.04/COPYING b/Build/source/libs/xpdf/xpdf-3.04/COPYING deleted file mode 100644 index a43ea2126fb..00000000000 --- a/Build/source/libs/xpdf/xpdf-3.04/COPYING +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 675 Mass Ave, Cambridge, MA 02139, USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - 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.

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.

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.

(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] - - -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.

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.

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. - -AUTHOR - The xpdf software and documentation are copyright 1996-2014 Glyph & - Cog, LLC. - -SEE ALSO - pdftops(1), pdftotext(1), pdftohtml(1), pdfinfo(1), pdffonts(1), pdfde- - tach(1), pdftoppm(1), pdftopng(1), pdfimages(1), xpdfrc(5) - http://www.foolabs.com/xpdf/ - - - - 28 May 2014 xpdf(1) diff --git a/Build/source/libs/xpdf/xpdf-3.04/doc/xpdfrc.5 b/Build/source/libs/xpdf/xpdf-3.04/doc/xpdfrc.5 deleted file mode 100644 index afb8d950795..00000000000 --- a/Build/source/libs/xpdf/xpdf-3.04/doc/xpdfrc.5 +++ /dev/null @@ -1,697 +0,0 @@ -.\" Copyright 2002-2014 Glyph & Cog, LLC -.TH xpdfrc 5 "28 May 2014" -.SH NAME -xpdfrc \- configuration file for Xpdf tools (version 3.04) -.SH DESCRIPTION -All of the Xpdf tools read a single configuration file. 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 -Arguments may be quoted, using "double-quote" characters, e.g., for -file names that contain spaces. -.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 psUseCropBoxAsPage " yes | no" -If set to "yes", PostScript output treats the CropBox as the page size. -By default, this is "no", and the MediaBox is used as the page size. -.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 psLZW " yes | no" -If set to "yes", the LZWEncode filter will be used for lossless -compression in PostScript output; if set to "no", the RunLengthEncode -filter will be used instead. LZW generates better compression -(smaller PS files), but may not be supported by some printers. This -defaults to "yes". -.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 psMinLineWidth " float" -Set the minimum line width, in points, for PostScript output. The -default value is 0 (no minimum). -.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 psRasterSliceSize " pixels" -When rasterizing pages, pdftops splits the page into horizontal -"slices", to limit memory usage. This option sets the maximum slice -size, in pixels. This defaults to 20000000 (20 million). -.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 "yes". -.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 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 mapExtTrueTypeFontsViaUnicode " yes | no" -When rasterizing text using an external TrueType font, there are two -options for handling character codes. If -mapExtTrueTypeFontsViaUnicode is set to "yes", Xpdf will use the font -encoding/ToUnicode info to map character codes to Unicode, and then -use the font's Unicode cmap to map Unicode to GIDs. If -mapExtTrueTypeFontsViaUnicode is set to "no", Xpdf will assume the -character codes are GIDs (i.e., use an identity mapping). This -defaults to "yes". -.TP -.BI enableXFA " yes | no" -If set to "yes", an XFA form (if present) will be rendered in place of -an AcroForm. If "no", an XFA form will never be rendered. This -defaults to "yes". -.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.

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. - - Arguments may be quoted, using "double-quote" characters, e.g., for - file names that contain spaces. - - 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". - - psUseCropBoxAsPage yes | no - If set to "yes", PostScript output treats the CropBox as the - page size. By default, this is "no", and the MediaBox is used - as the page size. - - 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". - - psLZW yes | no - If set to "yes", the LZWEncode filter will be used for lossless - compression in PostScript output; if set to "no", the RunLength- - Encode filter will be used instead. LZW generates better com- - pression (smaller PS files), but may not be supported by some - printers. This defaults to "yes". - - 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". - - psMinLineWidth float - Set the minimum line width, in points, for PostScript output. - The default value is 0 (no minimum). - - 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". - - psRasterSliceSize pixels - When rasterizing pages, pdftops splits the page into horizontal - "slices", to limit memory usage. This option sets the maximum - slice size, in pixels. This defaults to 20000000 (20 million). - - 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 "yes". - -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". - - 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". - - mapExtTrueTypeFontsViaUnicode yes | no - When rasterizing text using an external TrueType font, there are - two options for handling character codes. If mapExtTrueType- - FontsViaUnicode is set to "yes", Xpdf will use the font encod- - ing/ToUnicode info to map character codes to Unicode, and then - use the font's Unicode cmap to map Unicode to GIDs. If mapExt- - TrueTypeFontsViaUnicode is set to "no", Xpdf will assume the - character codes are GIDs (i.e., use an identity mapping). This - defaults to "yes". - - enableXFA yes | no - If set to "yes", an XFA form (if present) will be rendered in - place of an AcroForm. If "no", an XFA form will never be ren- - dered. This defaults to "yes". - - 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". - -EXAMPLES - The following is a sample xpdfrc file. - - # 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 - enableFreeType yes - launchCommand viewer-script - urlCommand "netscape -remote 'openURL(%s)'" - - -FILES - /usr/local/etc/xpdfrc - This is the default location for the system-wide configuration - file.

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.

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 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 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 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 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 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. + +3.04 (2014-may-28) +------------------ +New text extractor. +Added the pdftohtml tool. +Added the pdftopng tool. +New trapezoid-based rasterizer core (for performance). +Generate appearance streams for Line, PolyLine, and Polygon + annotations. +Added the closeWindowOrQuit command, and changed the default binding + for ctrl-W from closeWindow to closeWindowOrQuit. +Implemented the new AES-256 mode (R=6, Acrobat X). +Add an object cache. +Added a small cache for object streams. +Modify PSOutputDev to use LZW compression instead of RLE, with a + fallback to RLE if the "psLZW no" setting is given. +Pdfinfo now prints page rotation info. +Modified ImageOutputDev, used by pdfimages, to output the masks and + soft masks used when drawing images. +Remove non-printable characters from error output, just in case they + might cause problems for the terminal program. +Added initial support for Code3of9 bar codes in XFA forms. +Added the mapExtTrueTypeFontsViaUnicode xpdfrc command. +Apply stroke adjustment to rectangular images and clipping regions (in + addition to strokes and fills). +Decode JPEG 2000 images at less than full resolution if the full res + image isn't needed (i.e., if the raw image is higher resolution than + the output). +Implemented knockout groups. +Removed t1lib support. +Added support for images with 16-bit components. +Rewrote the Dict class to use a hash table; as a side effect, this + handles dictionaries with multiple definitions for a key, which are + in violation of the spec, but Acrobat appears to handle. +The transformed line width computation -- used to implement the + minLineWidth setting, and the hairline threshold in monochrome mode -- + was incorrect. +Pdftops was not correctly handling the case where it couldn't find + a 16-bit font -- this led to crashes and/or invalid PostScript. +A bug in FlateStream::getBlock() was causing problems with narrow + images. +Use the correct _WIN32 define instead of WIN32. +Use copy-on-write for the clip path in SplashState (when doing gsave), + for performance. +Added a Solaris-specific entry to the ghostscript font search path. +SplashState was initializing line width to 0 instead of 1. +Abort processing on a content stream after getting 500 errors + (undefined operator, wrong number of args) -- this avoids very long + processing time for malicious PDF files using bogus RLE encoded + content streams. +Added the psUseCropBoxAsPage xpdfrc option; "pdftops -pagecrop" now + sets psUseCropBoxAsPage; "pdftops -pagecrop -paper match" now uses + the CropBox as the page size. +Re-architected the AcroForm support code into a separate AcroForm + module. +Fixed the handling of overprinting/transparency interaction, using + the CompatibleOverprint blend mode. +The TIFF predictor code for the 1-bit-per-pixel case was broken. +For triangle and patch mesh shadings (types 4-7) with color functions, + interpolate the function parameter not the color. +Check the fontFile/fontDir commands before (instead of after) doing + Base-14 substitution in PS output. +Correctly handle non-embedded TrueType fonts that have an Identity + ToUnicode mapping (display and PS output were failing). +Added support for XFA form rendering, including an "enableXFA" xpdfrc + setting. +Handle PFB Type 1 fonts when generating PostScript output. +Unwind any extraneous saved graphics state at the end of the page + (before drawing annotations). +Added some integer overflow checks in the GString class. +Handle 16-bit components in JPEG 2000 images. +ActualText spans can end without a valid font, in which case + TextPage::beginWord was crashing. +The Domain entry in function shadings wasn't being parsed correctly. +Fixed a bug in the JPEG decoder - successive approximation + (progressive mode) coefficients weren't being handled correctly. +Added a better infinite loop test to the xref parser. +When generating PostScript, merge reused TrueType fonts (if their + code-to-GID mappings are the same). +Tweak the Gouraud triangle shaded fill code to end the recursive + splitting if the triangles get sufficiently small. +Do bilinear interpolation when upsampling images. +When skipping extraneous image data from an inline image, look for + EI instead of just EI. +When writing to stdout on Windows, pdftoppm now sets the file mode to + binary. [Thanks to Robert Frunzke.] +Accept strings as well as names for the BaseFont entry in font + objects. +Removed the TEXTOUT_WORD_LIST config option (with the new text + extractor, this is always enabled). +Fixed a bug in the JBIG2 decoder (the TPGD context for template #3 in + readGenericBitmap was incorrect). +Rewrote the PostScriptFunction code for performance. +Handle 8-bit OpenType CFF fonts that are missing required tables in + the OpenType wrapper. +Handle tiling patterns with reversed coordinates in their bounding + boxes. +Added support for 64-bit file offsets, i.e., PDF files larger than + 2GB. +Optimize the code that rasterizes pattern-filled image masks. +Added support for Mac OS X system fonts (Base-14 only). +The backdrop color in luminosity-type soft mask groups was not being + handled correctly. +Modified behavior of "pdftops -paper match -duplex ..." - it will now + duplex consecutive same-sized pages. +Tweak the handling of degenerate fills ('moveto lineto fill') to + match Adobe. +Don't honor the OPM=1 setting with ICCBased CMYK color spaces. +Whole-word searches were treating certain punctuation (Unicode number + separators and terminators) as part of the word, e.g., searching for + "foo" would not match "foo,". +Use the TextString class everywhere it makes sense. +Removed the unnecessary segment sort in Splash (performance + optimization). +Handle hyperlinks that use Widget-type annotations. +Fix up the integer overflow checks to avoid issues with clever + compilers. [Thanks to Nickolai Zeldovich.] +Correctly handle streams with missing Length entries in damaged PDF + files. +Added a compile-time option (LOAD_FONTS_FROM_MEM) to load fonts from + memory rather than temporary files on disk. +Added the psRasterSliceSize xpdfrc option. +Fixed a case in the JPEG 2000 arithmetic decoder where extra data is + present in packet i, and needs to be saved for use in packet i+1. +Fixed a bug in the JPEG 2000 decoder related to images with fewer than + 8 bits per component. +Handle the case in PSOutputDev where slice size overflows a 32-bit + integer. +Add (partial) support for TrueType cmap format 2. +Always pass FT_LOAD_NO_BITMAP to FreeType -- bitmaps apparently fail + with rotated characters. +Support fonts specified in ExtGState dictionaries. +Annotations with empty Border arrays should not draw a border. +Fix the CMap parser to handle large CID ranges. +Check for Type 3 CharProcs that call q or Q before the d0/d1 operator, + and treat them as uncacheable. +Invert the selection color when starting in reverse video mode. +Device{Gray,RGB,CMYK} cannot be mapped via a resource dict. +Changed the PS output for masked images (explicit and color key + masking): use a plain old clip path instead of rectclip to avoid + array overflows. +Check the StemSnapH/V arrays when converting Type 1C fonts to Type 1 - + if there are any duplicate or out-of-order values, skip that + StemSnapH/V array. +Added the psMinLineWidth xpdfrc setting. +Fix an obscure issue in converting TrueType fonts to Type 42, related + to empty glyph descriptions (12 zero bytes). +Pdftops now reports an error if there were any I/O errors writing to + the PS output file. +Fix vertical text (CJK fonts) in PS output -- offset the character + origin correctly. +Increased the number of digits used by pdfimages for the image number + from three to four. +Handle right-to-left (e.g., Arabic) ligatures correctly in the text + extractor. +Added the -loc and -locPS options to pdffonts. +Extend the object parser recursion limit to cover Stream::addFilters() + / Stream::makeFilters() - to avoid another possibility of stack + overflow. +Disable FreeType autohinting, because it can fail badly with font + subsets that use invalid glyph names -- except in the case of Type 1 + fonts, which look much better with light autohinting. +Modified the rasterizer pipeline functions to process a scan line at a + time (for performance). +Removed VMS build support (it hasn't been updated in ages). +Removed pdftotext's '-htmlmeta' option (use pdftohtml instead). +PSOutputDev's font/form setup code, and pdffonts, were not scanning + soft mask groups in ExtGState dictionaries. +Invalid DCT input (e.g., from a damaged PDF file) could overflow the + dctClip array. +When upsampling an image mask or image with a large resulting image + size, do it in stream mode instead of prescaling the whole image + (to avoid running out of memory). +Added infinite loop detection to pdffonts. diff --git a/Build/source/libs/xpdf/xpdf-src/COPYING b/Build/source/libs/xpdf/xpdf-src/COPYING new file mode 100644 index 00000000000..a43ea2126fb --- /dev/null +++ b/Build/source/libs/xpdf/xpdf-src/COPYING @@ -0,0 +1,339 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc. + 675 Mass Ave, Cambridge, MA 02139, USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + 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.

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.

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 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.

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.

(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] + + -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.

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. + +AUTHOR + The xpdf software and documentation are copyright 1996-2014 Glyph & + Cog, LLC. + +SEE ALSO + pdftops(1), pdftotext(1), pdftohtml(1), pdfinfo(1), pdffonts(1), pdfde- + tach(1), pdftoppm(1), pdftopng(1), pdfimages(1), xpdfrc(5) + http://www.foolabs.com/xpdf/ + + + + 28 May 2014 xpdf(1) diff --git a/Build/source/libs/xpdf/xpdf-src/doc/xpdfrc.5 b/Build/source/libs/xpdf/xpdf-src/doc/xpdfrc.5 new file mode 100644 index 00000000000..afb8d950795 --- /dev/null +++ b/Build/source/libs/xpdf/xpdf-src/doc/xpdfrc.5 @@ -0,0 +1,697 @@ +.\" Copyright 2002-2014 Glyph & Cog, LLC +.TH xpdfrc 5 "28 May 2014" +.SH NAME +xpdfrc \- configuration file for Xpdf tools (version 3.04) +.SH DESCRIPTION +All of the Xpdf tools read a single configuration file. 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 +Arguments may be quoted, using "double-quote" characters, e.g., for +file names that contain spaces. +.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 psUseCropBoxAsPage " yes | no" +If set to "yes", PostScript output treats the CropBox as the page size. +By default, this is "no", and the MediaBox is used as the page size. +.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 psLZW " yes | no" +If set to "yes", the LZWEncode filter will be used for lossless +compression in PostScript output; if set to "no", the RunLengthEncode +filter will be used instead. LZW generates better compression +(smaller PS files), but may not be supported by some printers. This +defaults to "yes". +.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 psMinLineWidth " float" +Set the minimum line width, in points, for PostScript output. The +default value is 0 (no minimum). +.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 psRasterSliceSize " pixels" +When rasterizing pages, pdftops splits the page into horizontal +"slices", to limit memory usage. This option sets the maximum slice +size, in pixels. This defaults to 20000000 (20 million). +.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 "yes". +.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 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 mapExtTrueTypeFontsViaUnicode " yes | no" +When rasterizing text using an external TrueType font, there are two +options for handling character codes. If +mapExtTrueTypeFontsViaUnicode is set to "yes", Xpdf will use the font +encoding/ToUnicode info to map character codes to Unicode, and then +use the font's Unicode cmap to map Unicode to GIDs. If +mapExtTrueTypeFontsViaUnicode is set to "no", Xpdf will assume the +character codes are GIDs (i.e., use an identity mapping). This +defaults to "yes". +.TP +.BI enableXFA " yes | no" +If set to "yes", an XFA form (if present) will be rendered in place of +an AcroForm. If "no", an XFA form will never be rendered. This +defaults to "yes". +.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.

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. + + Arguments may be quoted, using "double-quote" characters, e.g., for + file names that contain spaces. + + 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". + + psUseCropBoxAsPage yes | no + If set to "yes", PostScript output treats the CropBox as the + page size. By default, this is "no", and the MediaBox is used + as the page size. + + 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". + + psLZW yes | no + If set to "yes", the LZWEncode filter will be used for lossless + compression in PostScript output; if set to "no", the RunLength- + Encode filter will be used instead. LZW generates better com- + pression (smaller PS files), but may not be supported by some + printers. This defaults to "yes". + + 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". + + psMinLineWidth float + Set the minimum line width, in points, for PostScript output. + The default value is 0 (no minimum). + + 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". + + psRasterSliceSize pixels + When rasterizing pages, pdftops splits the page into horizontal + "slices", to limit memory usage. This option sets the maximum + slice size, in pixels. This defaults to 20000000 (20 million). + + 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 "yes". + +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". + + 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". + + mapExtTrueTypeFontsViaUnicode yes | no + When rasterizing text using an external TrueType font, there are + two options for handling character codes. If mapExtTrueType- + FontsViaUnicode is set to "yes", Xpdf will use the font encod- + ing/ToUnicode info to map character codes to Unicode, and then + use the font's Unicode cmap to map Unicode to GIDs. If mapExt- + TrueTypeFontsViaUnicode is set to "no", Xpdf will assume the + character codes are GIDs (i.e., use an identity mapping). This + defaults to "yes". + + enableXFA yes | no + If set to "yes", an XFA form (if present) will be rendered in + place of an AcroForm. If "no", an XFA form will never be ren- + dered. This defaults to "yes". + + 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.
