Acrobat 3) support: + - look for trailer after first xref instead of at end of file. +Deal with font subsets by converting character names of the form + 'Cnnnn' to the appropriate character from the standard encoding. +Extract encoding from embedded Type 1 fonts. +Kludge to fill one-pixel thick polygons. +Changed X font encoding to use endash for hyphen (gets rid of too-long + hyphens). +Handle Resources key in Pages dictionaries (needed for pstoedit + output). +Fix comment handling in Parser (needed for pstoedit output). +Move Bezier curve conversion from GfxState to XOutputDev; look at + flatness parameter in GfxState. +Change all of the path functions in XOutputDev (stroke, fill, clip) to + use the same path transformation/conversion function. +Rewrote PostScript output driver as a subclass of OutputDev; removed + duplicated code (ps_ functions) from Gfx. +Fixed bug in xref code with small (< 1024 bytes) PDF files. +Implemented BX/EX operators. +Added PDFDoc class. + + +0.6 (96-nov-12) +--------------- +Add support for PostScript output to stdout (-) and to a command + (|lpr); added -ps option and psFile resource. +Decryption is implemented but not included in the distribution due to + legal restrictions: the decryption algorithm is a trade secret of + RSA, Inc., and the U.S.A. still has bogus export controls on + cryptography software. +Added .xpdfrc config file: + - Added fontmap parameter: user can map PDF font names to X fonts. + - Added fontpath parameter: search for Type 1 font if encoding is + not in PDF file. +Incremental display: display is updated after every 200 commands. +Added forward and backward by-10-page buttons. +Links: + - Implement links with "Launch" actions that point to PDF files. + - Draw borders around links. + - Handle links with named destinations. + - GoToR links specify a page number instead of a page reference. +Optimizations: + - Rewrote Stream to use buffering, and added lookChar() functions; + rewrote Lexer to take advantage of this. + - Use hash tables for name->code mapping in font encodings. + - Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and + changed the flatness test. +Added file name to window title. +Implemented RunLength filter. +Implemented forms. +Convert ObjType to an enum. +Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with + incorrect PDF files. +Changed color selection so that very pale colors don't map to white. +Fixed bug in CCITTFax filter (multiple make-up codes). +In GString::clear(): need to set length to 0 before calling resize(). +Base initial window size on first displayed page, not page 1; deal + correctly with rotated pages. +Added ltkGetIntResource() and LTKApp::getIntResource(). +PostScript output fixes: + - Escape backslashes in strings. + - When doing ASCII85 encoding, keep both chars of EOF marker ('~>') + on same line. + - Add extra line '%-EOD-' after image data streams; call wrapper + functions for image and imagemask which look for this line -- this + should fix the 'too much data in stream' bug. + - Font tags can be reused for different fonts on different pages -- + so use font object reference (number/generation) instead. +Initialize character widths to zero (this caused crashes on OSF/1). +Handle image masks which go outside of pixmap. +Makefile.config changes: + - Remove -o in C++ compile rule. + - Add $(AR) variable. +Code which read char widths from font dictionary read all but the last + width. +Add 'return 0;' to main() in xpdf and pdftops. +Allow fonts to use StandardEncoding. +Convert man pages to VMS help files. + +0.7 (97-may-28) +--------------- +Implemented FlateDecode filter (for PDF 1.2). +Basic xref table reconstruction for damaged files +New pdftotext program converts PDF to plain text. +Implemented menus in LTK; added a menu to xpdf. +Added open and save functions; allow xpdf to start without any PDF + file. +Implemented text find. +Implemented text select/copy. +Change mouse cursor when it's over a link. +Embed Type 1 fonts in PostScript output. +Moved rotate functions to menu; added quit to menu. +Fixed stroke color bug in PostScript output (was using fill color + instead of stroke color; this sometimes caused lines to be missing + (white) in PostScript output). +Support Launch-type links -- pops up a dialog before executing + anything. Expects the A (action) dictionary to contain a Unix + dictionary with F (file) and P (paremeter) keys just like the Win + dictionary. +A moveto op all by itself should just be discarded, instead of + generating a subpath with one point (this was causing seg faults). +Balanced parentheses in strings don't need to be escaped. +Tj operator in PostScript prolog didn't check for zero when dividing + by length of string. +Implemented selection in LTK; TextIn widgets support dragging/copy/ + paste. +Handle font subsets that use hex character codes. +Added icon pixmap; added the XPMLIB and NO_XPM variables to + Makefile.config. +Fixed subtle bug in use of horizontal scaling parameter (it affects + only the width of drawn characters, not positioning done in text + space). +Memory testing (with DEBUG_MEM): + - gmalloc now fills memory blocks with garbage to catch unitialized + fields. + - gfree fills memory blocks with garbage to catch uses of freed + blocks. +Handle image masks which go off the pixmap on the top and/or left. +Fixed inline functions which had two return statements (to make the + HP, SCO, and other cfront-based compilers happy). +Fixed bug which caused seg faults when following a link to a different + file (info in LinkGoto object was used after link was deleted by + loadFile). +If page content is an array of streams, the streams are concatenated; + objects and commands can span multiple streams. +If file open fails, try lower-casing and upper-casing the file name. +Commands should end when lexer sees a '/' character. +GString::append(char *, int) was broken. +Changed LTKScrollingCanvas redraw to be more efficient: copy as much + as possible from window before copying from off-screen pixmap. +Ignore gs (set extended graphics state) operator. +Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the + weird colorspaces are not yet implemented). +Named destinations (for links) can be strings as well as names; deal + with the names tree in the catalog. +Clip to the page CropBox. +Added '-q' to gzip options (to suppress warnings, in case user has -v + in GZIP env var). +Added 'include Makefile.config' to top-level Makefile. +Added INSTALL variable to Makefile.config; used in top-level + Makefile. +Always initialize LinkDest left/bottom/top/right/zoom fields (bogus + floating point values were causing crashes on Alpha). +Added Makefile.config options for Digital Unix (DEC compilers), HP-UX + (HP compilers), SCO Unix, and Evans & Sutherland ES/OS. +Added flag to set stream mode in fopen call for VMS. +Rewrote Link module. +Pages with no contents shouldn't cause an error message. +In PostScript output: pdfImM needs to set fill color before doing + imagemask. +If font doesn't specify character widths, use widths from built-in + font, based on font flags. +Fixed LTK scrollbar to delay before repeating and to control the + period between repeats. +Removed window/widget copy() methods (they were untested and unused). +Unknown filter types produce a single error message instead of a + stream of errors. +Added a dummy target in top-level Makefile so making individual + executables (e.g., 'make pdftops') should now work. +Added optional xpdf-flip.ltk with buttons on right side instead of + bottom of window. + +0.7a (98-feb-22) +---------------- +Moved find command from menu to toolbar button ('f' key still works). +Support TrueColor visuals. +Added a -cmap option and a installCmap resource to install a private + colormap. +Mouse button 2 pans the window. +Selecting a URI link now executes a configurable command (from the + urlCommand resource). +Added a "link info" display which shows the URL or file for the link + under the mouse. +Don't draw (or convert to PostScript) text drawn in render modes 3 and + 7 -- this is invisible text, used by Acrobat Capture; this text is + still passed to the TextPage object so that selection works. +Recognize (and quietly ignore) marked content operators (BMC, BDC, + EMC, MP, DP). +Recognize new color-setting operators (scn, SCN). +Added A4_PAPER option. +Embed external Type 1 font files (this currently only works with PFA + files). +Added "-level1" option (in xpdf and pdftops) to generate Level 1 + PostScript. +Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT + flag, and use configure to autodetect (for HP-UX). +Fixed appendToPath() to behave reasonably when appending ".." to root + directory. +Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf + to crash under OSF/1). +ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and + could run past the end of the stream in damaged files. +Handle hex escapes (#xx) in names. Still allow the name /# for + backward-compatibility. +Check for NULL characters in encoding array in GfxFont.cc (was calling + strcmp() with NULL which crashed under Solaris). +PageAttrs::PageAttrs() didn't initialize crop box boundaries. +Changed uses of lookup() to lookupNF() in XRef.cc. +Fixed type checking of operators which take a variable number of + args. +Gfx::buildImageStream() doesn't need to check for parser (since I got + rid of the bogus array-of-command thing). +XOutputFont matches on font reference instead of font tag (similar to + PSOutputDev fix). +Fixed bug in position calculation for multi-char substitutions in + XOutputDev. +Cleaned up local variables which hid class variables. +Optimized variable length decoding in CCITTFaxStream. +Set link border width to zero if Border dictionary entry is missing. +Throw away zero-length strings in TextOutputDev -- they don't have + valid xMin/xMax values. +Swapped order of XLIBS and XPMLIB in xpdf/Makefile. +Deleted 'LTKApp::' in function declaration in LTKApp.h. +Changed '(XKeyEvent *)&event' to '&event.xkey' in LTKApp.cc. +Check that the link rectangle coordinates are in the correct order, + and swap if necessary. +TextOutputDev didn't set text to NULL, which caused pdftotext to + segfault if it couldn't open it's output file. +Fixed a hash table search bug in GfxFontEncoding::getCharCode(). +Cleaned up colorspace code: rewrote GfxColorSpace and added + GfxImageColorMap; cleaned up PSOutputDev::doImage. +Handle named colorspaces in images. +Correctly set the default color after a colorspace change. +Old setcolor operators now set the colorspace. +Fixed bug with uncompressed blocks in FlateStream. +Fixed bug with fixed Huffman code table in FlateStream. +Added hash table of X windows (for LTKWindow and LTKWidget) to LTKApp + and replaced calls to XQueryTree with hash table searches -- this + avoids a roundtrip to the server for each event and also fixes the + problem where XQueryTree crashed if the window no longer existed + (with leftover events from a destroyed window). (Thanks to Yair + Lenga for the suggestion.) +Create a new GC for selection -- xor black and white (instead of LTK + foreground and background). +Fixed crash with blank lines in .xpdfrc. +Allow spaces in font descriptors in fontmap lines in .xpdfrc. +Check for bogus object number in XRef::fetch(). +Use MacRomanEncoding for TrueType fonts that don't specify an + encoding. +Certain PDF generators apparently don't include FontDescriptors for + Arial, TimesNewRoman, and CourierNew -- set GfxFont flags + appropriately. +Fixed a bug in width guessing in GfxFont -- sans serif and serif were + swapped. +Rewrote XRef::readXRef() to avoid using a parser to read the xref + entries. +Added NO_TEXT_SELECT option. +Ignore APPn/COM/etc. markers in DCT streams. +Replaced select() with XMultiplexInput() in LTKApp.cc for VMS. +Handle WM_DELETE_WINDOW protocol -- if you ask the window manager to + delete the xpdf window, xpdf will exit cleanly; other + windows/dialogs are simply closed. +Optimized DCT decoder; switched to integer arithmetic. +The "/Type /Annots" field in an annotation dictionary is optional. +Check for null nameTree in Catalog::findDest(). +In XOutputDev, search user font map before default font map. +Added "normal" SETWIDTH parameter to all font descriptors in + XOutputDev (some systems have a narrow-width Helvetica font). +Added FOPEN_READ_BIN and FOPEN_WRITE_BIN to support Win32. +Added a hack which allows better font substitution for some Type 3 + fonts. Also allow character names of the form /nn and /nnn. +Added and to LTKApp.cc (needed by AIX and IRIX + for bzero() declaration for FD_ZERO). + +0.80 (98-nov-27) +---------------- +Support for some Japanese fonts (Type 0 fonts using the Adobe-Japan1-2 + character collection, horizontal only). +Added pdfinfo application. +Added pdftopbm application. +Added pdfimages application. +Added -papercolor option and .paperColor resource. +Fixed divide-by-zero problem in XOutputDev Type 3 font matrix kludge. +Font subset char names can be 'Bxx' as well as 'Cxx' and 'Gxx'. +Fixed bug in color space conversion in DCTStream filter (YCC->RGB was + correct, YCCK->CMYK was broken). +Added XRef::getDocInfo() and PDFDoc::getDocInfo() to support pdfinfo. +Optimized GfxImageColorMap. +Lexer::getStream(), getPos(), and setPos() check for null stream. +Decryption code now does strings as well as streams. +ASCII85 decoder rounds short tuples up instead of down. +CropBox and MediaBox can be non-integers. +PostScript output: + - Use a rectangle operator. + - Call setpagedevice with page size. + - Insert %%PageOrientation comments. + - Add paper size flags (-paperw and -paperh) to xpdf and pdftops. + - If HAVE_POPEN is not defined, and user tries to print to '|...', + the PSOutputDev destructor tried to write to the PS file. + - Added support for forms (pdftops -form). +Removed error messages for empty paths in stroke, fill, etc. operators. +Don't allow flatnesses less than 1 in XOutputDev (this speeds up + rendering a little bit when there are lots of tiny curves). +Moved the font subset character name guessing from GfxFont to + XOutputDev and TextOutputDev - now these files print correctly. +Cast argument to XFree() to XPointer; add XPointer definition where + necessary (portability fixes). +Various minor VMS fixes. +Changes to configure script and Makefiles: + - Print a warning if X is missing. + - Use C++ when checking select() argument type (HP-UX). + - Use 0 instead of NULL when checking select(). + - Default to gcc instead of c++. + - Get rid of AC_C_INLINE -- this is meant for C, not C++. + - Changed -USE_GZIP to -DUSE_GZIP. + - Added ability to compile ouside of the source tree. + - Added .cc.o rule to {goo,ltk,xpdf}/Makefile.in. + - Added @LIBS@ to XLIBS in xpdf/Makefile.in. + - In top-level Makefile.in: added '-' to clean commands; added + distclean rule. + - Create install directories. + - Use INSTALL_DATA (instead of INSTALL) for man pages. + - Changed xpdf-ltk.h rule to avoid leaving an empty file when + ltkbuild fails. + - Change things so that by default, ltkbuild is not built and + xpdf-ltk.h is not rebuilt. + - Use AM_PROG_CC_STDC to add compiler flags for ANSI C. + - Modify autoconf's builtin macros to check for xlC. + - Use Steve Robbins' smr_CHECK_LIB to test for pixmap library (Xpm) + -- this should fix the problems on systems that have the library + but not the include file. + - Added better test for sys/select.h, sys/bsdtypes.h, strings.h, + bstring.h. + - New VMS make scripts from Martin P.J. Zinser. + - Moved dependences into Makefile.in -- this gets rid of problems + with 'cc -MM' (which is gcc-specific) and 'include Makefile.dep' + (which isn't supported by all make implementations). Also changed + all non-system include files to '#include "..."' (from '<...>'). +Tweaked the TextOutputDev heuristics slightly. +Modify Gfx to use a stack of resources -- this is necessary for Form + XObjects, which can define their own local resources; also modified + PSOutputDev to dump fonts used by forms. +Look for excessively large MediaBox (compared to CropBox) and shrink + it to CropBox. +Minor fix to scrolling when dragging a selection. +Various patches for pdftex and Win32 support. +Deal with Separation colorspaces by using their alternate colorspace + entry. +Added PBMOutputDev for pdftopbm application. +Added ImageOutputDev for pdfimages application. +Separated XOutputDev into LTKOutputDev + XOutputDev. +Added support for 1-D and mixed 1-D/2-D (Group 3) decoding to + CCITTDecode filter. +Added resetImage(), getImagePixel(), and skipImageLine() to Stream + class; used these in XOutputDev, PSOutputDev, and ImageOutputDev. +Implemented predictor for LZW and Flate filters. +In pdfImM1 in PSOutputDev prolog: div should be idiv. +Changed output from printUsage() function in parseargs to look nicer. + +0.90 (99-aug-02) +---------------- +Added Type 1/1C font rendering, using t1lib. +Added "backward" and "forward" buttons. +Added fit-page and fit-page-width zoom factors; replaced zoom-in and + zoom-out buttons with a zoom popup menu. +Type 1C fonts are converted to Type 1 and embedded in PostScript. +Support vertical Japanese text. +Added Japanese text support (EUC-JP) to pdftotext. +Bumped PDF version to 1.3. Added stub functions for ri and sh + operators. (But there are still some missing 1.3 features.) +Added -raw option to pdftotext. +Minor changes to allow compiling under MS Visual C++ 5.0. +Top-level makefile: changed 'mkdir -p' to '-mkdir -p'. +Configure script: added X_CFLAGS to smr_CHECK_LIB(Xpm). +Added Xpm_CFLAGS to xpdf/Makefile.in (this is needed to get the -I for + the xpm includes). +Rewrote code that handles font encodings; added support for Type 1C + fonts. +In the setpagedevice dictionary in PostScript output - added a + /Policies entry which tells the PS interpreter to scale the page to + fit the available paper. +Changed PageUp behavior slightly: move to bottom (instead of top) of + previous page. +TextPage used character's dx (width + char space) instead of just its + width. +Read base URI from document Catalog (for URI-type links). +Minor change to configure script to avoid using 'unset'. +Fixed bugs in CropBox inheritance. +Fixed a bug in resource stack handling for form objects. +Display forms even if they have a missing/incorrect FormType. +Fixed a bug in stream predictors -- the predictor parameters (width, + comps, bits) don't need to match the actual image parameters. + Completely rearranged the predictor code. +Fixed PostScript output to correctly handle stream predictors. +Don't segfault on empty (zero-page) documents. +Added the xpdf.viKeys feature. +Added the ffi and ffl ligatures to XOutputDev and TextOutputDev. +Pdftotext and pdfimages now check okToCopy(). +Added a '-q' flag to all programs (except pdfinfo) to suppress + messages and errors. +Deal with DeviceN colorspaces by using their alternate colorspace + entry. +Change PostScript output so setpagedevice is only called once, at the + very beginning of the document (to avoid problems on duplex + printers). +Changes to configure script and makefiles for DOS/DJGPP. +FontEncoding::getCharCode() looked for (code>0) instead of (code>=0). +Added keypad arrow keys, etc. to xpdf. +Minor changes to gfile.{h,cpp} () to compile under VC++. +Fixed CCITTFaxStream to correctly handle all parameters. +Modifications to gfile.{h,cc} for Acorn. +Some minor changes for OS/2. +Added 'SHELL = /bin/sh' to Makefiles. +Compare file version to pdfVersionNum+0.0001 to avoid floating point + precision problems. +Added LDFLAGS to Makefiles. +Removed strip entirely from configure and Makefiles. +Fixed a bug in choosing the correct DCTStream color transform. + +0.91 (2000-aug-14) +------------------ +Added TrueType font rendering, using FreeType. +Support for Chinese fonts (Type 0 fonts using the Adobe-GB1-2 + character collection). +Decryption code is included with the main distribution (now that the + US export regulations are a little bit less irrational). +Added (very basic) support for generating PostScript with Japanese + fonts -- only tested with ghostscript so far. +Added support for generating EPS files (pdftops -eps). +Much-improved image filtering in xpdf (for downsampling and for + transforms other than 0/90/180/270-degree rotations). +Implemented a basic full-screen (presentation) mode (xpdf + -fullscreen). (There is currently no way to switch between window + and full-screen modes on the fly -- this will be fixed in a later + release.) +Added "reload" menu item. +Do a better job with anti-aliased Type 1 fonts on non-white + backgrounds. +Handle Lab color spaces. +Handle non-null user passwords. +Avoid security hole with tmpnam()/fopen() -- added openTempFile() in + goo/gfile.cc. [Thanks to Joseph S. Myers for pointing this out.] +Filter out quote marks (' and ") in URLs before running urlCommand to + avoid a potential security hole. [Thanks to Frank Doepper for + pointing this out.] +Fixed TrueColor detection to look at the complete list of available + visuals, not just the default visual. +In gfile.h, changed NAMLEN(dirent) macro to NAMLEN(d). +Removed copyright character from start-up banners. +In the open and save dialogs, if the open/save button is pressed with + no file name, the dialog is not canceled. +Added Xpm_CFLAGS to ltk/Makefile. +XOutputDev::updateLineAttrs was using dashLength before it was + defined. +In top-level Makefile.in, use INSTALL_PROGRAM instead of INSTALL. +In man page, recommend -q instead of -err in .mailcap. +Changes for GNOME / Bonobo support: + - Separated Stream classes into BaseStream and FilterStream trees. + - Got rid of all FileStream-specific stuff. + - Added a PDFDoc constructor that takes a BaseStream* instead of a + file name. +Allow newlines inside strings (Photoshop does this). +Don't require whitespace between tokens in consecutive content + streams (for pages that specify an array of streams). +Look at MissingWidth when constructing font character widths array. +Fixed a bug that caused incorrect PostScript output for images that + use 8-bit indexed color spaces with < 256 colors in the palette. +Handle case where embedded font file is bad (this was seg faulting). +Minor changes for Windows/pdftex. +Work around a bug in PDF files from the IBM patent server. +Fixed bugs in PostScript form generation: use pdfStartPage instead of + pdfSetup; problem with inline images. +Minor bug fix in FlateStream::loadFixedCodes(). +Added %%DocumentMedia and %%PageMedia comments to the PostScript so + that gsview (a Windows frontend for ghostscript) gets the right + paper size. +Draw AcroForm fields that have appearance annotations. +Bounds check gray, CMYK, and RGB values (in GfxColor). +Moved the link border drawing code into Page (from PDFDoc). +Minor modifications for pdftohtml. +PSOutputDev: use the Type 3 font scaling kludge from XOutputDev. +Separation color spaces were handled incorrectly in images. +Fixed a bug with form bounding boxes. +Modified the t1lib support -- replace libt1x code with my own code. + Type 1 and TrueType fonts are now handled similarly, and clipping + works on Type 1 fonts. +Don't print copyright banner (xpdf); add -v switch to get copyright + and version info (all apps); get rid of -err switch (xpdf). +Automatically reload the PDF file if it has been changed, i.e., if the + modification time is different. +Fixed a memory (malloc size) bug in CCITTFaxStream. +Fixed two bugs in FontEncoding::hash() -- handle zero-length character + names (which were found in a (buggy?) PDF file), and handle + character names with high-bit-set characters (use unsigned ints). +Added PDFDoc::isLinearized() and corresponding code in pdfinfo.cc. +Handle files with an incorrect page count in the Pages dictionary + (FOP, from the Apache project produces a page count of 0). +Handle TrueType equivalents to the Base14 fonts (Arial, TimesNewRoman, + CourierNew) -- Adobe's tools use these names without embedding the + fonts. +Tweaked the Type 3 font sizing kludge. +Changed pdfimages (ImageOutputDev) so it doesn't output JPEG files for + 4-component color spaces, since these seem to confuse most image + viewers. +Added support for generating OPI comments (pdftops -opi). +In XOutputDev::drawImage() and drawImageMask(), check for images that + are completely off-page. +Use the provided alternate or a default (DeviceGray/RGB/CMYK) color + space for ICCBased color spaces. +Incorporated MacOS-specific code from Leonard Rosenthol. +Configure script switches to C++ for the strings.h/bstring.h test. +Gfx::opRestore() calls clearPath() to handle (apparently) buggy PDF + files produced by FreeHand. +The /Type field in most dictionaries is optional (PDF 1.3 change). +Move printCommands variable definition into Gfx.cc. +If page is smaller than paper, center the PostScript output. +Fix a minor bug in the SELECT_TAKES_INT detection in the configure + script. +TextOutputDev filters out control characters. +Changed enough occurrences of 'char *' to 'const char *' to keep gcc + 2.95 from barfing. +Support for Latin-2 and Latin-5 in pdftotext (however, this will only + work if the PDF file contains correct font encodings, which seems to + be rare). +TextOutputDev converts "eightoldstyle" to "eight", etc. +Don't use the return value from sprintf() -- most systems return the + length, but some return the string. +Minor fixes for SunOS 4. +Configure script looks for both select() and fd_set in sys/select.h. +Configure script checks for gethostbyname() in -lbsd (for LynxOS). +Fix missing closepath bug in PostScript output. +Change PostScript portrait/landscape mode selection so it only uses + landscape if the page width is greater than the paper width. +Tweaked the VMS code in makePathAbsolute(). + +0.91a (2000-oct-11) +------------------- +Implemented separable CMYK PostScript output (the -level1sep switch to + pdftops). +Implemented Pattern color spaces with tiling patterns (polygon fills + only). +Implemented Stamp annotations. +Implemented Named link actions. +Fixed a really dumb bug in the TrueColor code in SFont (which affects + both Type 1 and TrueType font rendering on 16-bit displays). +Rewrote the GfxColorSpace / GfxColor code. +Switched from djgppcfg to dj_make.bat (from Michael Richmond). +Bug in the Type 1 encoding parser -- couldn't handle lines of the form + 'dup NNN/name put' (with no space between the code and the name). +Fixed the mkstemp() test in configure.in -- switched from + AC_TRY_COMPILE to AC_TRY_LINK and added . +Added DESTDIR to top-level Makefile.in. +Fixed an incorrect OPI comment in PSOutputDev. +Minor tweak to the CCITTFax code to avoid writing past the end of an + array on an invalid data stream. +Xpdf crashed if the user selected 'reload' when no document was + loaded. +Look for character names of the form "xx" (two hex digits with no + leading alphabetic char) and 'cNNN' (decimal digits with a leading + alphabetic char that happens to be a hex digit). +FlateStream didn't correctly handle zero-length streams. +Xref reconstruction didn't handle the case where the opening "<<" + immediately followed "trailer" with no intervening whitespace. +Fix the %%DocumentSuppliedResources comment in EPS output. +Scale annotations to fit their rectangles. +Added Stream::close() to handle cases (e.g., patterns) where a Stream + object is used multiple times before it is deleted. +Added the topLevel arg to Gfx::go() so it doesn't call out->dump() for + every pattern element (and form). +Rearranged the GfxResources class. +Clean up white space handling in Lexer. +Make the dpi parameter to PDFDoc::displayPage etc. a double - this + avoids margin gaps with fit-page and fit-width. +Fix a rounding problem in xpdf.cc that was causing the window to + sometimes be one pixel too small. +Fixed a minor bug in dealing with Base-14 TrueType font names. +Fixed Lab -> RGB color space conversion. +Added support for opacity values (from PDF 1.4) to GfxState and + OutputDev.

[Thanks to 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 Phillip Ezolt.] +Handle XObjects with recursive references in their Resources + dictionaries (in PSOutputDev). +Change PSOutputDev to deal with invalid PDF files that use + non-embedded TrueType fonts with no encoding. +Check for undersized Widths arrays in fonts. +Add bounds checking code to Array class. +Updated VMS build scripts. [Thanks to Martin Zinser.] +Tweak the TrueType font handling code (again): + - char codes in symbolic fonts may or may not be offset by 0xf000 + - discard empty tables because they sometimes confuse FreeType +Fixed bounds checking in the Flate decoder. +Removed a bogus error message for exponential functions without + explicit C0/C1 values. [Thanks to Hartmut Henkel.] +Handle the other Unicode cmap type (platform=0) in TrueType fonts. +Added support for the SGI Motif horizontal paned window widget. + [Thanks to Felix Ritter.] +Ignore extra elements in link destination arrays. +Accept external Type 1 font files with a suffix of ".ps" or no suffix + at all. +Add a bounds check in the DCT decoder. +Added instructions for building xpdf.exe under cygwin/XFree86. +Tweaked the word separation parameter for raw-mode text extraction. + +2.03 (2003-oct-10) +------------------ +Rewrote the text extractor to: + - do a better job with rotated text; + - handle right-to-left scripts; + - be faster. +Changed the zoom setting to use a percentage (relative to 72 dpi) + instead of a zoom "factor". +If the PDF file has an outline, open the outline pane initially. +Added -f and -l options to pdfinfo; print multiple page sizes. +The HAVE_XTAPPSETEXITFLAG test in XPDFApp.cc was backwards. +The BitsPerComponent entry is optional in image mask objects. +Render any annotation with an appearance stream, instead of just + Widget and Stamp annotations. +Fix a bug in the TrueType font checker: the test for an unsorted + 'loca' table was wrong. +Modify the TrueType cmap selection algorithm yet again to try to match + Adobe's behavior. +Changed sqrt(2) to sqrt(2.0) in pdfinfo.cc to make various compilers + happy. +Fixed a deadlock problem (when MULTITHREADING is set); cleaned up some + other problems with the locking code. +Fixed a bug in the interpolation code for type 0 (sampled) functions. +Implemented type 1 (function-based) shaded fills. +Fixed some stupid bugs in the JBIG2 decoder (introduced with the + previous optimization work). +Fixed a typo in the code that parses vertical font metrics for CID + fonts that was causing a seg fault. +Fixed a couple of bugs that were causing seg faults with badly damaged + PDF files. +Limit the number of nested Forms to avoid infinite recursion (in buggy + PDF files). +Add a special case for rectangular clip regions - make sure these + don't drop pixels on the right and bottom edges. +Tell FreeType not to use glyph bitmaps when in anti-aliased mode. +Read all of the border style info for links. +All of the shaded fill types now do at least one bisection to avoid + problems when the colors at the endpoints of the domain are the + same. +If the Length2 parameter for an embedded Type 1 font was incorrect + (too small), pdftops was losing font data. +Deal with (broken) DCT streams that use the same component ID number + for different components. +The MediaBox page attribute was not being inherited correctly. +Fixed a bug in the Type 1C font converter related to local + subroutines. +The Type 1C -> Type 1 font converter was allocating the font dictionary + one slot too small. +Added a missing private dictionary entry to Type 1 fonts generated by + the Type 1C converter.

[Thanks to 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. +Corrected the handling of the 'extend' parameters in radial shadings. +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. diff --git a/Build/source/libs/xpdf/COPYING b/Build/source/libs/xpdf/COPYING new file mode 100644 index 00000000000..a43ea2126fb --- /dev/null +++ b/Build/source/libs/xpdf/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.

The resulting library (libt1) and + include files (t1lib.h and t1libx.h) should be placed somewhere on + the standard search paths. Alternatively, when you configure xpdf, + you can use the following options to tell configure where to find + the t1lib files: + + --with-t1-library=PATH + --with-t1-includes=PATH + +* Install FreeType 2 (this is required). WARNING: You must have + version 2.0.5 or newer.

The default is + /usr/lib/X11/app-defaults. + + If you need to pass specific options to the C and/or C++ compiler, + you can set the CFLAGS and/or CXXFLAGS environment variables before + running the configure script.
