Amber, a.k.a. Acrobat 3) support: - - look for trailer after first xref instead of at end of file. -Deal with font subsets by converting character names of the form - 'Cnnnn' to the appropriate character from the standard encoding. -Extract encoding from embedded Type 1 fonts. -Kludge to fill one-pixel thick polygons. -Changed X font encoding to use endash for hyphen (gets rid of too-long - hyphens). -Handle Resources key in Pages dictionaries (needed for pstoedit - output). -Fix comment handling in Parser (needed for pstoedit output). -Move Bezier curve conversion from GfxState to XOutputDev; look at - flatness parameter in GfxState. -Change all of the path functions in XOutputDev (stroke, fill, clip) to - use the same path transformation/conversion function. -Rewrote PostScript output driver as a subclass of OutputDev; removed - duplicated code (ps_ functions) from Gfx. -Fixed bug in xref code with small (< 1024 bytes) PDF files. -Implemented BX/EX operators. -Added PDFDoc class. - - -0.6 (96-nov-12) ---------------- -Add support for PostScript output to stdout (-) and to a command - (|lpr); added -ps option and psFile resource. -Decryption is implemented but not included in the distribution due to - legal restrictions: the decryption algorithm is a trade secret of - RSA, Inc., and the U.S.A. still has bogus export controls on - cryptography software. -Added .xpdfrc config file: - - Added fontmap parameter: user can map PDF font names to X fonts. - - Added fontpath parameter: search for Type 1 font if encoding is - not in PDF file. -Incremental display: display is updated after every 200 commands. -Added forward and backward by-10-page buttons. -Links: - - Implement links with "Launch" actions that point to PDF files. - - Draw borders around links. - - Handle links with named destinations. - - GoToR links specify a page number instead of a page reference. -Optimizations: - - Rewrote Stream to use buffering, and added lookChar() functions; - rewrote Lexer to take advantage of this. - - Use hash tables for name->code mapping in font encodings. - - Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and - changed the flatness test. -Added file name to window title. -Implemented RunLength filter. -Implemented forms. -Convert ObjType to an enum. -Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with - incorrect PDF files. -Changed color selection so that very pale colors don't map to white. -Fixed bug in CCITTFax filter (multiple make-up codes). -In GString::clear(): need to set length to 0 before calling resize(). -Base initial window size on first displayed page, not page 1; deal - correctly with rotated pages. -Added ltkGetIntResource() and LTKApp::getIntResource(). -PostScript output fixes: - - Escape backslashes in strings. - - When doing ASCII85 encoding, keep both chars of EOF marker ('~>') - on same line. - - Add extra line '%-EOD-' after image data streams; call wrapper - functions for image and imagemask which look for this line -- this - should fix the 'too much data in stream' bug. - - Font tags can be reused for different fonts on different pages -- - so use font object reference (number/generation) instead. -Initialize character widths to zero (this caused crashes on OSF/1). -Handle image masks which go outside of pixmap. -Makefile.config changes: - - Remove -o in C++ compile rule. - - Add $(AR) variable. -Code which read char widths from font dictionary read all but the last - width. -Add 'return 0;' to main() in xpdf and pdftops. -Allow fonts to use StandardEncoding. -Convert man pages to VMS help files. - -0.7 (97-may-28) ---------------- -Implemented FlateDecode filter (for PDF 1.2). -Basic xref table reconstruction for damaged files -New pdftotext program converts PDF to plain text. -Implemented menus in LTK; added a menu to xpdf. -Added open and save functions; allow xpdf to start without any PDF - file. -Implemented text find. -Implemented text select/copy. -Change mouse cursor when it's over a link. -Embed Type 1 fonts in PostScript output. -Moved rotate functions to menu; added quit to menu. -Fixed stroke color bug in PostScript output (was using fill color - instead of stroke color; this sometimes caused lines to be missing - (white) in PostScript output). -Support Launch-type links -- pops up a dialog before executing - anything. Expects the A (action) dictionary to contain a Unix - dictionary with F (file) and P (paremeter) keys just like the Win - dictionary. -A moveto op all by itself should just be discarded, instead of - generating a subpath with one point (this was causing seg faults). -Balanced parentheses in strings don't need to be escaped. -Tj operator in PostScript prolog didn't check for zero when dividing - by length of string. -Implemented selection in LTK; TextIn widgets support dragging/copy/ - paste. -Handle font subsets that use hex character codes. -Added icon pixmap; added the XPMLIB and NO_XPM variables to - Makefile.config. -Fixed subtle bug in use of horizontal scaling parameter (it affects - only the width of drawn characters, not positioning done in text - space). -Memory testing (with DEBUG_MEM): - - gmalloc now fills memory blocks with garbage to catch unitialized - fields. - - gfree fills memory blocks with garbage to catch uses of freed - blocks. -Handle image masks which go off the pixmap on the top and/or left. -Fixed inline functions which had two return statements (to make the - HP, SCO, and other cfront-based compilers happy). -Fixed bug which caused seg faults when following a link to a different - file (info in LinkGoto object was used after link was deleted by - loadFile). -If page content is an array of streams, the streams are concatenated; - objects and commands can span multiple streams. -If file open fails, try lower-casing and upper-casing the file name. -Commands should end when lexer sees a '/' character. -GString::append(char *, int) was broken. -Changed LTKScrollingCanvas redraw to be more efficient: copy as much - as possible from window before copying from off-screen pixmap. -Ignore gs (set extended graphics state) operator. -Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the - weird colorspaces are not yet implemented). -Named destinations (for links) can be strings as well as names; deal - with the names tree in the catalog. -Clip to the page CropBox. -Added '-q' to gzip options (to suppress warnings, in case user has -v - in GZIP env var). -Added 'include Makefile.config' to top-level Makefile. -Added INSTALL variable to Makefile.config; used in top-level - Makefile. -Always initialize LinkDest left/bottom/top/right/zoom fields (bogus - floating point values were causing crashes on Alpha). -Added Makefile.config options for Digital Unix (DEC compilers), HP-UX - (HP compilers), SCO Unix, and Evans & Sutherland ES/OS. -Added flag to set stream mode in fopen call for VMS. -Rewrote Link module. -Pages with no contents shouldn't cause an error message. -In PostScript output: pdfImM needs to set fill color before doing - imagemask. -If font doesn't specify character widths, use widths from built-in - font, based on font flags. -Fixed LTK scrollbar to delay before repeating and to control the - period between repeats. -Removed window/widget copy() methods (they were untested and unused). -Unknown filter types produce a single error message instead of a - stream of errors. -Added a dummy target in top-level Makefile so making individual - executables (e.g., 'make pdftops') should now work. -Added optional xpdf-flip.ltk with buttons on right side instead of - bottom of window. - -0.7a (98-feb-22) ----------------- -Moved find command from menu to toolbar button ('f' key still works). -Support TrueColor visuals. -Added a -cmap option and a installCmap resource to install a private - colormap. -Mouse button 2 pans the window. -Selecting a URI link now executes a configurable command (from the - urlCommand resource). -Added a "link info" display which shows the URL or file for the link - under the mouse. -Don't draw (or convert to PostScript) text drawn in render modes 3 and - 7 -- this is invisible text, used by Acrobat Capture; this text is - still passed to the TextPage object so that selection works. -Recognize (and quietly ignore) marked content operators (BMC, BDC, - EMC, MP, DP). -Recognize new color-setting operators (scn, SCN). -Added A4_PAPER option. -Embed external Type 1 font files (this currently only works with PFA - files). -Added "-level1" option (in xpdf and pdftops) to generate Level 1 - PostScript. -Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT - flag, and use configure to autodetect (for HP-UX). -Fixed appendToPath() to behave reasonably when appending ".." to root - directory. -Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf - to crash under OSF/1). -ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and - could run past the end of the stream in damaged files. -Handle hex escapes (#xx) in names. Still allow the name /# for - backward-compatibility. -Check for NULL characters in encoding array in GfxFont.cc (was calling - strcmp() with NULL which crashed under Solaris). -PageAttrs::PageAttrs() didn't initialize crop box boundaries. -Changed uses of lookup() to lookupNF() in XRef.cc. -Fixed type checking of operators which take a variable number of - args. -Gfx::buildImageStream() doesn't need to check for parser (since I got - rid of the bogus array-of-command thing). -XOutputFont matches on font reference instead of font tag (similar to - PSOutputDev fix). -Fixed bug in position calculation for multi-char substitutions in - XOutputDev. -Cleaned up local variables which hid class variables. -Optimized variable length decoding in CCITTFaxStream. -Set link border width to zero if Border dictionary entry is missing. -Throw away zero-length strings in TextOutputDev -- they don't have - valid xMin/xMax values. -Swapped order of XLIBS and XPMLIB in xpdf/Makefile. -Deleted 'LTKApp::' in function declaration in LTKApp.h. -Changed '(XKeyEvent *)&event' to '&event.xkey' in LTKApp.cc. -Check that the link rectangle coordinates are in the correct order, - and swap if necessary. -TextOutputDev didn't set text to NULL, which caused pdftotext to - segfault if it couldn't open it's output file. -Fixed a hash table search bug in GfxFontEncoding::getCharCode(). -Cleaned up colorspace code: rewrote GfxColorSpace and added - GfxImageColorMap; cleaned up PSOutputDev::doImage. -Handle named colorspaces in images. -Correctly set the default color after a colorspace change. -Old setcolor operators now set the colorspace. -Fixed bug with uncompressed blocks in FlateStream. -Fixed bug with fixed Huffman code table in FlateStream. -Added hash table of X windows (for LTKWindow and LTKWidget) to LTKApp - and replaced calls to XQueryTree with hash table searches -- this - avoids a roundtrip to the server for each event and also fixes the - problem where XQueryTree crashed if the window no longer existed - (with leftover events from a destroyed window). (Thanks to Yair - Lenga for the suggestion.) -Create a new GC for selection -- xor black and white (instead of LTK - foreground and background). -Fixed crash with blank lines in .xpdfrc. -Allow spaces in font descriptors in fontmap lines in .xpdfrc. -Check for bogus object number in XRef::fetch(). -Use MacRomanEncoding for TrueType fonts that don't specify an - encoding. -Certain PDF generators apparently don't include FontDescriptors for - Arial, TimesNewRoman, and CourierNew -- set GfxFont flags - appropriately. -Fixed a bug in width guessing in GfxFont -- sans serif and serif were - swapped. -Rewrote XRef::readXRef() to avoid using a parser to read the xref - entries. -Added NO_TEXT_SELECT option. -Ignore APPn/COM/etc. markers in DCT streams. -Replaced select() with XMultiplexInput() in LTKApp.cc for VMS. -Handle WM_DELETE_WINDOW protocol -- if you ask the window manager to - delete the xpdf window, xpdf will exit cleanly; other - windows/dialogs are simply closed. -Optimized DCT decoder; switched to integer arithmetic. -The "/Type /Annots" field in an annotation dictionary is optional. -Check for null nameTree in Catalog::findDest(). -In XOutputDev, search user font map before default font map. -Added "normal" SETWIDTH parameter to all font descriptors in - XOutputDev (some systems have a narrow-width Helvetica font). -Added FOPEN_READ_BIN and FOPEN_WRITE_BIN to support Win32. -Added a hack which allows better font substitution for some Type 3 - fonts. Also allow character names of the form /nn and /nnn. -Added <strings.h> and <bstring.h> 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.
