|
---|
| 2 | ---------------
|
---|
| 3 | First public release.
|
---|
| 4 |
|
---|
| 5 |
|
---|
| 6 | 0.3 (96-jan-13)
|
---|
| 7 | ---------------
|
---|
| 8 | LZW patent workaround.
|
---|
| 9 | Implemented inline images.
|
---|
| 10 | Fixed (mostly) disjoint polygon fills.
|
---|
| 11 | Added remote server stuff.
|
---|
| 12 | Added page number on command line.
|
---|
| 13 | Fixed problem with font encodings which caused character misalignment.
|
---|
| 14 | Fixed inverted CCITT decoding and inverted image mask drawing.
|
---|
| 15 | Now compiles under gcc 2.7.x (ignore those stupid 'unused parameter'
|
---|
| 16 | warnings).
|
---|
| 17 | Many minor bug fixes and optimizations.
|
---|
| 18 |
|
---|
| 19 |
|
---|
| 20 | 0.4 (96-apr-24)
|
---|
| 21 | ---------------
|
---|
| 22 | Implemented DCT filter.
|
---|
| 23 | Implemented PostScript output; wrote pdftops program.
|
---|
| 24 | Implemented links.
|
---|
| 25 | Implemented font rotation -- I was wrong: X11R6 servers *do* support
|
---|
| 26 | font rotation (by specifying a matrix in place of a size).
|
---|
| 27 | Added bindings for Home/End, Page Up/Down, arrow keys.
|
---|
| 28 | Added initialZoom resource and -z option.
|
---|
| 29 | Added geometry resource and -g option.
|
---|
| 30 | Fixed image size off-by-one bug.
|
---|
| 31 | Fixed bug where page content is reference to an array of streams.
|
---|
| 32 | Cleaned up uninitialized variables which were causing random problems
|
---|
| 33 | on various platforms.
|
---|
| 34 | Manually skip whitespace before calling atoi() for startxref.
|
---|
| 35 | Replaced calls to XrmCombineFileDatabase() with calls to
|
---|
| 36 | XrmGetFileDatabase() and XrmMergeDatabases() so it will work under
|
---|
| 37 | older versions of X.
|
---|
| 38 | Fixed problem with reading multiple xref tables in updated PDF files.
|
---|
| 39 | Check for encryption and print appropriate error message.
|
---|
| 40 | Rudimentary dithering of images.
|
---|
| 41 | Fixed bug in CCITTFax filter (pass mode followed by horizontal mode).
|
---|
| 42 | Optimized drawImage() and drawImageMask().
|
---|
| 43 | Changed several things to ease porting:
|
---|
| 44 | - changed '__inline' to 'inline' (to adhere to the ANSI standard)
|
---|
| 45 | - surrounded interface/implementation pragmas with #ifdef _GNUC__
|
---|
| 46 | - got rid of empty array initializer lists
|
---|
| 47 | - moved Operator type definition from Gfx.cc to Gfx.h
|
---|
| 48 | - renamed String, uint, etc.
|
---|
| 49 | - ability to uncompress to file (NO_POPEN and USE_GZIP flags)
|
---|
| 50 | - added definitions of XK_Page_Up/Down and XPointer for old versions
|
---|
| 51 | of X
|
---|
| 52 | For VMS port:
|
---|
| 53 | - use correct Xdefaults name for VMS, get rid of ltkGetHomeDir()
|
---|
| 54 | - added '#include <stddef.h>' before all X includes
|
---|
| 55 | - renamed files with multiple periods in their names
|
---|
| 56 | Fixed window resizing infinite oscillation bug.
|
---|
| 57 | Fixed problem with string-type (as opposed to stream-type) indexed
|
---|
| 58 | color space lookup tables (which are used in inline images).
|
---|
| 59 | If an X font is not found, try smaller and then larger sizes (this is
|
---|
| 60 | useful for old or broken X servers which can't scale bitmap fonts).
|
---|
| 61 | Added -rgb (color cube size) option.
|
---|
| 62 | Various minor bug fixes.
|
---|
| 63 |
|
---|
| 64 |
|
---|
| 65 | 0.5 (96-may-23)
|
---|
| 66 | ---------------
|
---|
| 67 | Fixed bug in LTKWindow which broke the remote server mode.
|
---|
| 68 | Fixed PostScript output:
|
---|
| 69 | - doesn't seg fault if file is unwritable.
|
---|
| 70 | - incorrect DSC comment - need colon in '%%Page:'.
|
---|
| 71 | - use 'imagemask' command for masks.
|
---|
| 72 | - output filters in the correct order.
|
---|
| 73 | - Stream::isBinary() checks the next-to-bottom, not top, stream.
|
---|
| 74 | - if page width > height, rotate it 90 degrees.
|
---|
| 75 | - if page is larger than paper size, scale it down.
|
---|
| 76 | Set default MediaBox to 8.5" x 11" to deal with non-compliant PDF
|
---|
| 77 | files which don't specify a MediaBox.
|
---|
| 78 | Added DEBUG_MEM stuff in gmem.c and gmempp.cc.
|
---|
| 79 | Fixed memory leaks:
|
---|
| 80 | - LTKWindow didn't delete the LTKBox.
|
---|
| 81 | - LinkAction needs a virtual destructor.
|
---|
| 82 | Use $(RANLIB) variable in goo/Makefile and ltk/Makefile.
|
---|
| 83 | Allocate image data after calling XCreateImage, using
|
---|
| 84 | image->bytes_per_line -- works in 24-bit mode now.
|
---|
| 85 | DCTStream rounds width of rowBuf lines up to the next multiple of
|
---|
| 86 | mcuWidth, so last MCU doesn't run off end of buffer.
|
---|
| 87 | Increase size of block (from 255 to 1024 bytes) read at end of file to
|
---|
| 88 | search for 'startxref'.
|
---|
| 89 | Skip past garbage at start of file, look for '%PDF'.
|
---|
| 90 | Moved more compiler options out of Makefiles into Makefile.config.
|
---|
| 91 | Top-level Makefile uses '$(MAKE)' instead of 'make' for making
|
---|
| 92 | subdirectories.
|
---|
| 93 | Space/PageDown/Next and Backspace/PageUp/Previous now moves to
|
---|
| 94 | next/previous page if already scrolled to bottom/top of current
|
---|
| 95 | page.
|
---|
| 96 |
|
---|
| 97 |
|
---|
| 98 | 0.5a (96-jul-09)
|
---|
| 99 | ----------------
|
---|
| 100 | [not a public release]
|
---|
| 101 | For PDF 1.2 (a.k.a. Amber, a.k.a. Acrobat 3) support:
|
---|
| 102 | - look for trailer after first xref instead of at end of file.
|
---|
| 103 | Deal with font subsets by converting character names of the form
|
---|
| 104 | 'Cnnnn' to the appropriate character from the standard encoding.
|
---|
| 105 | Extract encoding from embedded Type 1 fonts.
|
---|
| 106 | Kludge to fill one-pixel thick polygons.
|
---|
| 107 | Changed X font encoding to use endash for hyphen (gets rid of too-long
|
---|
| 108 | hyphens).
|
---|
| 109 | Handle Resources key in Pages dictionaries (needed for pstoedit
|
---|
| 110 | output).
|
---|
| 111 | Fix comment handling in Parser (needed for pstoedit output).
|
---|
| 112 | Move Bezier curve conversion from GfxState to XOutputDev; look at
|
---|
| 113 | flatness parameter in GfxState.
|
---|
| 114 | Change all of the path functions in XOutputDev (stroke, fill, clip) to
|
---|
| 115 | use the same path transformation/conversion function.
|
---|
| 116 | Rewrote PostScript output driver as a subclass of OutputDev; removed
|
---|
| 117 | duplicated code (ps_ functions) from Gfx.
|
---|
| 118 | Fixed bug in xref code with small (< 1024 bytes) PDF files.
|
---|
| 119 | Implemented BX/EX operators.
|
---|
| 120 | Added PDFDoc class.
|
---|
| 121 |
|
---|
| 122 |
|
---|
| 123 | 0.6 (96-nov-12)
|
---|
| 124 | ---------------
|
---|
| 125 | Add support for PostScript output to stdout (-) and to a command
|
---|
| 126 | (|lpr); added -ps option and psFile resource.
|
---|
| 127 | Decryption is implemented but not included in the distribution due to
|
---|
| 128 | legal restrictions: the decryption algorithm is a trade secret of
|
---|
| 129 | RSA, Inc., and the U.S.A. still has bogus export controls on
|
---|
| 130 | cryptography software.
|
---|
| 131 | Added .xpdfrc config file:
|
---|
| 132 | - Added fontmap parameter: user can map PDF font names to X fonts.
|
---|
| 133 | - Added fontpath parameter: search for Type 1 font if encoding is
|
---|
| 134 | not in PDF file.
|
---|
| 135 | Incremental display: display is updated after every 200 commands.
|
---|
| 136 | Added forward and backward by-10-page buttons.
|
---|
| 137 | Links:
|
---|
| 138 | - Implement links with "Launch" actions that point to PDF files.
|
---|
| 139 | - Draw borders around links.
|
---|
| 140 | - Handle links with named destinations.
|
---|
| 141 | - GoToR links specify a page number instead of a page reference.
|
---|
| 142 | Optimizations:
|
---|
| 143 | - Rewrote Stream to use buffering, and added lookChar() functions;
|
---|
| 144 | rewrote Lexer to take advantage of this.
|
---|
| 145 | - Use hash tables for name->code mapping in font encodings.
|
---|
| 146 | - Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and
|
---|
| 147 | changed the flatness test.
|
---|
| 148 | Added file name to window title.
|
---|
| 149 | Implemented RunLength filter.
|
---|
| 150 | Implemented forms.
|
---|
| 151 | Convert ObjType to an enum.
|
---|
| 152 | Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with
|
---|
| 153 | incorrect PDF files.
|
---|
| 154 | Changed color selection so that very pale colors don't map to white.
|
---|
| 155 | Fixed bug in CCITTFax filter (multiple make-up codes).
|
---|
| 156 | In GString::clear(): need to set length to 0 before calling resize().
|
---|
| 157 | Base initial window size on first displayed page, not page 1; deal
|
---|
| 158 | correctly with rotated pages.
|
---|
| 159 | Added ltkGetIntResource() and LTKApp::getIntResource().
|
---|
| 160 | PostScript output fixes:
|
---|
| 161 | - Escape backslashes in strings.
|
---|
| 162 | - When doing ASCII85 encoding, keep both chars of EOF marker ('~>')
|
---|
| 163 | on same line.
|
---|
| 164 | - Add extra line '%-EOD-' after image data streams; call wrapper
|
---|
| 165 | functions for image and imagemask which look for this line -- this
|
---|
| 166 | should fix the 'too much data in stream' bug.
|
---|
| 167 | - Font tags can be reused for different fonts on different pages --
|
---|
| 168 | so use font object reference (number/generation) instead.
|
---|
| 169 | Initialize character widths to zero (this caused crashes on OSF/1).
|
---|
| 170 | Handle image masks which go outside of pixmap.
|
---|
| 171 | Makefile.config changes:
|
---|
| 172 | - Remove -o in C++ compile rule.
|
---|
| 173 | - Add $(AR) variable.
|
---|
| 174 | Code which read char widths from font dictionary read all but the last
|
---|
| 175 | width.
|
---|
| 176 | Add 'return 0;' to main() in xpdf and pdftops.
|
---|
| 177 | Allow fonts to use StandardEncoding.
|
---|
| 178 | Convert man pages to VMS help files.
|
---|
| 179 |
|
---|
| 180 | 0.7 (97-may-28)
|
---|
| 181 | ---------------
|
---|
| 182 | Implemented FlateDecode filter (for PDF 1.2).
|
---|
| 183 | Basic xref table reconstruction for damaged files
|
---|
| 184 | New pdftotext program converts PDF to plain text.
|
---|
| 185 | Implemented menus in LTK; added a menu to xpdf.
|
---|
| 186 | Added open and save functions; allow xpdf to start without any PDF
|
---|
| 187 | file.
|
---|
| 188 | Implemented text find.
|
---|
| 189 | Implemented text select/copy.
|
---|
| 190 | Change mouse cursor when it's over a link.
|
---|
| 191 | Embed Type 1 fonts in PostScript output.
|
---|
| 192 | Moved rotate functions to menu; added quit to menu.
|
---|
| 193 | Fixed stroke color bug in PostScript output (was using fill color
|
---|
| 194 | instead of stroke color; this sometimes caused lines to be missing
|
---|
| 195 | (white) in PostScript output).
|
---|
| 196 | Support Launch-type links -- pops up a dialog before executing
|
---|
| 197 | anything. Expects the A (action) dictionary to contain a Unix
|
---|
| 198 | dictionary with F (file) and P (paremeter) keys just like the Win
|
---|
| 199 | dictionary.
|
---|
| 200 | A moveto op all by itself should just be discarded, instead of
|
---|
| 201 | generating a subpath with one point (this was causing seg faults).
|
---|
| 202 | Balanced parentheses in strings don't need to be escaped.
|
---|
| 203 | Tj operator in PostScript prolog didn't check for zero when dividing
|
---|
| 204 | by length of string.
|
---|
| 205 | Implemented selection in LTK; TextIn widgets support dragging/copy/
|
---|
| 206 | paste.
|
---|
| 207 | Handle font subsets that use hex character codes.
|
---|
| 208 | Added icon pixmap; added the XPMLIB and NO_XPM variables to
|
---|
| 209 | Makefile.config.
|
---|
| 210 | Fixed subtle bug in use of horizontal scaling parameter (it affects
|
---|
| 211 | only the width of drawn characters, not positioning done in text
|
---|
| 212 | space).
|
---|
| 213 | Memory testing (with DEBUG_MEM):
|
---|
| 214 | - gmalloc now fills memory blocks with garbage to catch unitialized
|
---|
| 215 | fields.
|
---|
| 216 | - gfree fills memory blocks with garbage to catch uses of freed
|
---|
| 217 | blocks.
|
---|
| 218 | Handle image masks which go off the pixmap on the top and/or left.
|
---|
| 219 | Fixed inline functions which had two return statements (to make the
|
---|
| 220 | HP, SCO, and other cfront-based compilers happy).
|
---|
| 221 | Fixed bug which caused seg faults when following a link to a different
|
---|
| 222 | file (info in LinkGoto object was used after link was deleted by
|
---|
| 223 | loadFile).
|
---|
| 224 | If page content is an array of streams, the streams are concatenated;
|
---|
| 225 | objects and commands can span multiple streams.
|
---|
| 226 | If file open fails, try lower-casing and upper-casing the file name.
|
---|
| 227 | Commands should end when lexer sees a '/' character.
|
---|
| 228 | GString::append(char *, int) was broken.
|
---|
| 229 | Changed LTKScrollingCanvas redraw to be more efficient: copy as much
|
---|
| 230 | as possible from window before copying from off-screen pixmap.
|
---|
| 231 | Ignore gs (set extended graphics state) operator.
|
---|
| 232 | Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the
|
---|
| 233 | weird colorspaces are not yet implemented).
|
---|
| 234 | Named destinations (for links) can be strings as well as names; deal
|
---|
| 235 | with the names tree in the catalog.
|
---|
| 236 | Clip to the page CropBox.
|
---|
| 237 | Added '-q' to gzip options (to suppress warnings, in case user has -v
|
---|
| 238 | in GZIP env var).
|
---|
| 239 | Added 'include Makefile.config' to top-level Makefile.
|
---|
| 240 | Added INSTALL variable to Makefile.config; used in top-level
|
---|
| 241 | Makefile.
|
---|
| 242 | Always initialize LinkDest left/bottom/top/right/zoom fields (bogus
|
---|
| 243 | floating point values were causing crashes on Alpha).
|
---|
| 244 | Added Makefile.config options for Digital Unix (DEC compilers), HP-UX
|
---|
| 245 | (HP compilers), SCO Unix, and Evans & Sutherland ES/OS.
|
---|
| 246 | Added flag to set stream mode in fopen call for VMS.
|
---|
| 247 | Rewrote Link module.
|
---|
| 248 | Pages with no contents shouldn't cause an error message.
|
---|
| 249 | In PostScript output: pdfImM needs to set fill color before doing
|
---|
| 250 | imagemask.
|
---|
| 251 | If font doesn't specify character widths, use widths from built-in
|
---|
| 252 | font, based on font flags.
|
---|
| 253 | Fixed LTK scrollbar to delay before repeating and to control the
|
---|
| 254 | period between repeats.
|
---|
| 255 | Removed window/widget copy() methods (they were untested and unused).
|
---|
| 256 | Unknown filter types produce a single error message instead of a
|
---|
| 257 | stream of errors.
|
---|
| 258 | Added a dummy target in top-level Makefile so making individual
|
---|
| 259 | executables (e.g., 'make pdftops') should now work.
|
---|
| 260 | Added optional xpdf-flip.ltk with buttons on right side instead of
|
---|
| 261 | bottom of window.
|
---|
| 262 |
|
---|
| 263 | 0.7a (98-feb-22)
|
---|
| 264 | ----------------
|
---|
| 265 | Moved find command from menu to toolbar button ('f' key still works).
|
---|
| 266 | Support TrueColor visuals.
|
---|
| 267 | Added a -cmap option and a installCmap resource to install a private
|
---|
| 268 | colormap.
|
---|
| 269 | Mouse button 2 pans the window.
|
---|
| 270 | Selecting a URI link now executes a configurable command (from the
|
---|
| 271 | urlCommand resource).
|
---|
| 272 | Added a "link info" display which shows the URL or file for the link
|
---|
| 273 | under the mouse.
|
---|
| 274 | Don't draw (or convert to PostScript) text drawn in render modes 3 and
|
---|
| 275 | 7 -- this is invisible text, used by Acrobat Capture; this text is
|
---|
| 276 | still passed to the TextPage object so that selection works.
|
---|
| 277 | Recognize (and quietly ignore) marked content operators (BMC, BDC,
|
---|
| 278 | EMC, MP, DP).
|
---|
| 279 | Recognize new color-setting operators (scn, SCN).
|
---|
| 280 | Added A4_PAPER option.
|
---|
| 281 | Embed external Type 1 font files (this currently only works with PFA
|
---|
| 282 | files).
|
---|
| 283 | Added "-level1" option (in xpdf and pdftops) to generate Level 1
|
---|
| 284 | PostScript.
|
---|
| 285 | Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT
|
---|
| 286 | flag, and use configure to autodetect (for HP-UX).
|
---|
| 287 | Fixed appendToPath() to behave reasonably when appending ".." to root
|
---|
| 288 | directory.
|
---|
| 289 | Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf
|
---|
| 290 | to crash under OSF/1).
|
---|
| 291 | ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and
|
---|
| 292 | could run past the end of the stream in damaged files.
|
---|
| 293 | Handle hex escapes (#xx) in names. Still allow the name /# for
|
---|
| 294 | backward-compatibility.
|
---|
| 295 | Check for NULL characters in encoding array in GfxFont.cc (was calling
|
---|
| 296 | strcmp() with NULL which crashed under Solaris).
|
---|
| 297 | PageAttrs::PageAttrs() didn't initialize crop box boundaries.
|
---|
| 298 | Changed uses of lookup() to lookupNF() in XRef.cc.
|
---|
| 299 | Fixed type checking of operators which take a variable number of
|
---|
| 300 | args.
|
---|
| 301 | Gfx::buildImageStream() doesn't need to check for parser (since I got
|
---|
| 302 | rid of the bogus array-of-command thing).
|
---|
| 303 | XOutputFont matches on font reference instead of font tag (similar to
|
---|
| 304 | PSOutputDev fix).
|
---|
| 305 | Fixed bug in position calculation for multi-char substitutions in
|
---|
| 306 | XOutputDev.
|
---|
| 307 | Cleaned up local variables which hid class variables.
|
---|
| 308 | Optimized variable length decoding in CCITTFaxStream.
|
---|
| 309 | Set link border width to zero if Border dictionary entry is missing.
|
---|
| 310 | Throw away zero-length strings in TextOutputDev -- they don't have
|
---|
| 311 | valid xMin/xMax values.
|
---|
| 312 | Swapped order of XLIBS and XPMLIB in xpdf/Makefile.
|
---|
| 313 | Deleted 'LTKApp::' in function declaration in LTKApp.h.
|
---|
| 314 | Changed '(XKeyEvent *)&event' to '&event.xkey' in LTKApp.cc.
|
---|
| 315 | Check that the link rectangle coordinates are in the correct order,
|
---|
| 316 | and swap if necessary.
|
---|
| 317 | TextOutputDev didn't set text to NULL, which caused pdftotext to
|
---|
| 318 | segfault if it couldn't open it's output file.
|
---|
| 319 | Fixed a hash table search bug in GfxFontEncoding::getCharCode().
|
---|
| 320 | Cleaned up colorspace code: rewrote GfxColorSpace and added
|
---|
| 321 | GfxImageColorMap; cleaned up PSOutputDev::doImage.
|
---|
| 322 | Handle named colorspaces in images.
|
---|
| 323 | Correctly set the default color after a colorspace change.
|
---|
| 324 | Old setcolor operators now set the colorspace.
|
---|
| 325 | Fixed bug with uncompressed blocks in FlateStream.
|
---|
| 326 | Fixed bug with fixed Huffman code table in FlateStream.
|
---|
| 327 | Added hash table of X windows (for LTKWindow and LTKWidget) to LTKApp
|
---|
| 328 | and replaced calls to XQueryTree with hash table searches -- this
|
---|
| 329 | avoids a roundtrip to the server for each event and also fixes the
|
---|
| 330 | problem where XQueryTree crashed if the window no longer existed
|
---|
| 331 | (with leftover events from a destroyed window). (Thanks to Yair
|
---|
| 332 | Lenga for the suggestion.)
|
---|
| 333 | Create a new GC for selection -- xor black and white (instead of LTK
|
---|
| 334 | foreground and background).
|
---|
| 335 | Fixed crash with blank lines in .xpdfrc.
|
---|
| 336 | Allow spaces in font descriptors in fontmap lines in .xpdfrc.
|
---|
| 337 | Check for bogus object number in XRef::fetch().
|
---|
| 338 | Use MacRomanEncoding for TrueType fonts that don't specify an
|
---|
| 339 | encoding.
|
---|
| 340 | Certain PDF generators apparently don't include FontDescriptors for
|
---|
| 341 | Arial, TimesNewRoman, and CourierNew -- set GfxFont flags
|
---|
| 342 | appropriately.
|
---|
| 343 | Fixed a bug in width guessing in GfxFont -- sans serif and serif were
|
---|
| 344 | swapped.
|
---|
| 345 | Rewrote XRef::readXRef() to avoid using a parser to read the xref
|
---|
| 346 | entries.
|
---|
| 347 | Added NO_TEXT_SELECT option.
|
---|
| 348 | Ignore APPn/COM/etc. markers in DCT streams.
|
---|
| 349 | Replaced select() with XMultiplexInput() in LTKApp.cc for VMS.
|
---|
| 350 | Handle WM_DELETE_WINDOW protocol -- if you ask the window manager to
|
---|
| 351 | delete the xpdf window, xpdf will exit cleanly; other
|
---|
| 352 | windows/dialogs are simply closed.
|
---|
| 353 | Optimized DCT decoder; switched to integer arithmetic.
|
---|
| 354 | The "/Type /Annots" field in an annotation dictionary is optional.
|
---|
| 355 | Check for null nameTree in Catalog::findDest().
|
---|
| 356 | In XOutputDev, search user font map before default font map.
|
---|
| 357 | Added "normal" SETWIDTH parameter to all font descriptors in
|
---|
| 358 | XOutputDev (some systems have a narrow-width Helvetica font).
|
---|
| 359 | Added FOPEN_READ_BIN and FOPEN_WRITE_BIN to support Win32.
|
---|
| 360 | Added a hack which allows better font substitution for some Type 3
|
---|
| 361 | fonts. Also allow character names of the form /nn and /nnn.
|
---|
| 362 | Added <strings.h> and <bstring.h> to LTKApp.cc (needed by AIX and IRIX
|
---|
| 363 | for bzero() declaration for FD_ZERO).
|
---|
| 364 |
|
---|
| 365 | 0.80 (98-nov-27)
|
---|
| 366 | ----------------
|
---|
| 367 | Support for some Japanese fonts (Type 0 fonts using the Adobe-Japan1-2
|
---|
| 368 | character collection, horizontal only).
|
---|
| 369 | Added pdfinfo application.
|
---|
| 370 | Added pdftopbm application.
|
---|
| 371 | Added pdfimages application.
|
---|
| 372 | Added -papercolor option and .paperColor resource.
|
---|
| 373 | Fixed divide-by-zero problem in XOutputDev Type 3 font matrix kludge.
|
---|
| 374 | Font subset char names can be 'Bxx' as well as 'Cxx' and 'Gxx'.
|
---|
| 375 | Fixed bug in color space conversion in DCTStream filter (YCC->RGB was
|
---|
| 376 | correct, YCCK->CMYK was broken).
|
---|
| 377 | Added XRef::getDocInfo() and PDFDoc::getDocInfo() to support pdfinfo.
|
---|
| 378 | Optimized GfxImageColorMap.
|
---|
| 379 | Lexer::getStream(), getPos(), and setPos() check for null stream.
|
---|
| 380 | Decryption code now does strings as well as streams.
|
---|
| 381 | ASCII85 decoder rounds short tuples up instead of down.
|
---|
| 382 | CropBox and MediaBox can be non-integers.
|
---|
| 383 | PostScript output:
|
---|
| 384 | - Use a rectangle operator.
|
---|
| 385 | - Call setpagedevice with page size.
|
---|
| 386 | - Insert %%PageOrientation comments.
|
---|
| 387 | - Add paper size flags (-paperw and -paperh) to xpdf and pdftops.
|
---|
| 388 | - If HAVE_POPEN is not defined, and user tries to print to '|...',
|
---|
| 389 | the PSOutputDev destructor tried to write to the PS file.
|
---|
| 390 | - Added support for forms (pdftops -form).
|
---|
| 391 | Removed error messages for empty paths in stroke, fill, etc. operators.
|
---|
| 392 | Don't allow flatnesses less than 1 in XOutputDev (this speeds up
|
---|
| 393 | rendering a little bit when there are lots of tiny curves).
|
---|
| 394 | Moved the font subset character name guessing from GfxFont to
|
---|
| 395 | XOutputDev and TextOutputDev - now these files print correctly.
|
---|
| 396 | Cast argument to XFree() to XPointer; add XPointer definition where
|
---|
| 397 | necessary (portability fixes).
|
---|
| 398 | Various minor VMS fixes.
|
---|
| 399 | Changes to configure script and Makefiles:
|
---|
| 400 | - Print a warning if X is missing.
|
---|
| 401 | - Use C++ when checking select() argument type (HP-UX).
|
---|
| 402 | - Use 0 instead of NULL when checking select().
|
---|
| 403 | - Default to gcc instead of c++.
|
---|
| 404 | - Get rid of AC_C_INLINE -- this is meant for C, not C++.
|
---|
| 405 | - Changed -USE_GZIP to -DUSE_GZIP.
|
---|
| 406 | - Added ability to compile ouside of the source tree.
|
---|
| 407 | - Added .cc.o rule to {goo,ltk,xpdf}/Makefile.in.
|
---|
| 408 | - Added @LIBS@ to XLIBS in xpdf/Makefile.in.
|
---|
| 409 | - In top-level Makefile.in: added '-' to clean commands; added
|
---|
| 410 | distclean rule.
|
---|
| 411 | - Create install directories.
|
---|
| 412 | - Use INSTALL_DATA (instead of INSTALL) for man pages.
|
---|
| 413 | - Changed xpdf-ltk.h rule to avoid leaving an empty file when
|
---|
| 414 | ltkbuild fails.
|
---|
| 415 | - Change things so that by default, ltkbuild is not built and
|
---|
| 416 | xpdf-ltk.h is not rebuilt.
|
---|
| 417 | - Use AM_PROG_CC_STDC to add compiler flags for ANSI C.
|
---|
| 418 | - Modify autoconf's builtin macros to check for xlC.
|
---|
| 419 | - Use Steve Robbins' smr_CHECK_LIB to test for pixmap library (Xpm)
|
---|
| 420 | -- this should fix the problems on systems that have the library
|
---|
| 421 | but not the include file.
|
---|
| 422 | - Added better test for sys/select.h, sys/bsdtypes.h, strings.h,
|
---|
| 423 | bstring.h.
|
---|
| 424 | - New VMS make scripts from Martin P.J. Zinser.
|
---|
| 425 | - Moved dependences into Makefile.in -- this gets rid of problems
|
---|
| 426 | with 'cc -MM' (which is gcc-specific) and 'include Makefile.dep'
|
---|
| 427 | (which isn't supported by all make implementations). Also changed
|
---|
| 428 | all non-system include files to '#include "..."' (from '<...>').
|
---|
| 429 | Tweaked the TextOutputDev heuristics slightly.
|
---|
| 430 | Modify Gfx to use a stack of resources -- this is necessary for Form
|
---|
| 431 | XObjects, which can define their own local resources; also modified
|
---|
| 432 | PSOutputDev to dump fonts used by forms.
|
---|
| 433 | Look for excessively large MediaBox (compared to CropBox) and shrink
|
---|
| 434 | it to CropBox.
|
---|
| 435 | Minor fix to scrolling when dragging a selection.
|
---|
| 436 | Various patches for pdftex and Win32 support.
|
---|
| 437 | Deal with Separation colorspaces by using their alternate colorspace
|
---|
| 438 | entry.
|
---|
| 439 | Added PBMOutputDev for pdftopbm application.
|
---|
| 440 | Added ImageOutputDev for pdfimages application.
|
---|
| 441 | Separated XOutputDev into LTKOutputDev + XOutputDev.
|
---|
| 442 | Added support for 1-D and mixed 1-D/2-D (Group 3) decoding to
|
---|
| 443 | CCITTDecode filter.
|
---|
| 444 | Added resetImage(), getImagePixel(), and skipImageLine() to Stream
|
---|
| 445 | class; used these in XOutputDev, PSOutputDev, and ImageOutputDev.
|
---|
| 446 | Implemented predictor for LZW and Flate filters.
|
---|
| 447 | In pdfImM1 in PSOutputDev prolog: div should be idiv.
|
---|
| 448 | Changed output from printUsage() function in parseargs to look nicer.
|
---|
| 449 |
|
---|
| 450 | 0.90 (99-aug-02)
|
---|
| 451 | ----------------
|
---|
| 452 | Added Type 1/1C font rendering, using t1lib.
|
---|
| 453 | Added "backward" and "forward" buttons.
|
---|
| 454 | Added fit-page and fit-page-width zoom factors; replaced zoom-in and
|
---|
| 455 | zoom-out buttons with a zoom popup menu.
|
---|
| 456 | Type 1C fonts are converted to Type 1 and embedded in PostScript.
|
---|
| 457 | Support vertical Japanese text.
|
---|
| 458 | Added Japanese text support (EUC-JP) to pdftotext.
|
---|
| 459 | Bumped PDF version to 1.3. Added stub functions for ri and sh
|
---|
| 460 | operators. (But there are still some missing 1.3 features.)
|
---|
| 461 | Added -raw option to pdftotext.
|
---|
| 462 | Minor changes to allow compiling under MS Visual C++ 5.0.
|
---|
| 463 | Top-level makefile: changed 'mkdir -p' to '-mkdir -p'.
|
---|
| 464 | Configure script: added X_CFLAGS to smr_CHECK_LIB(Xpm).
|
---|
| 465 | Added Xpm_CFLAGS to xpdf/Makefile.in (this is needed to get the -I for
|
---|
| 466 | the xpm includes).
|
---|
| 467 | Rewrote code that handles font encodings; added support for Type 1C
|
---|
| 468 | fonts.
|
---|
| 469 | In the setpagedevice dictionary in PostScript output - added a
|
---|
| 470 | /Policies entry which tells the PS interpreter to scale the page to
|
---|
| 471 | fit the available paper.
|
---|
| 472 | Changed PageUp behavior slightly: move to bottom (instead of top) of
|
---|
| 473 | previous page.
|
---|
| 474 | TextPage used character's dx (width + char space) instead of just its
|
---|
| 475 | width.
|
---|
| 476 | Read base URI from document Catalog (for URI-type links).
|
---|
| 477 | Minor change to configure script to avoid using 'unset'.
|
---|
| 478 | Fixed bugs in CropBox inheritance.
|
---|
| 479 | Fixed a bug in resource stack handling for form objects.
|
---|
| 480 | Display forms even if they have a missing/incorrect FormType.
|
---|
| 481 | Fixed a bug in stream predictors -- the predictor parameters (width,
|
---|
| 482 | comps, bits) don't need to match the actual image parameters.
|
---|
| 483 | Completely rearranged the predictor code.
|
---|
| 484 | Fixed PostScript output to correctly handle stream predictors.
|
---|
| 485 | Don't segfault on empty (zero-page) documents.
|
---|
| 486 | Added the xpdf.viKeys feature.
|
---|
| 487 | Added the ffi and ffl ligatures to XOutputDev and TextOutputDev.
|
---|
| 488 | Pdftotext and pdfimages now check okToCopy().
|
---|
| 489 | Added a '-q' flag to all programs (except pdfinfo) to suppress
|
---|
| 490 | messages and errors.
|
---|
| 491 | Deal with DeviceN colorspaces by using their alternate colorspace
|
---|
| 492 | entry.
|
---|
| 493 | Change PostScript output so setpagedevice is only called once, at the
|
---|
| 494 | very beginning of the document (to avoid problems on duplex
|
---|
| 495 | printers).
|
---|
| 496 | Changes to configure script and makefiles for DOS/DJGPP.
|
---|
| 497 | FontEncoding::getCharCode() looked for (code>0) instead of (code>=0).
|
---|
| 498 | Added keypad arrow keys, etc. to xpdf.
|
---|
| 499 | Minor changes to gfile.{h,cpp} (<windows.h>) to compile under VC++.
|
---|
| 500 | Fixed CCITTFaxStream to correctly handle all parameters.
|
---|
| 501 | Modifications to gfile.{h,cc} for Acorn.
|
---|
| 502 | Some minor changes for OS/2.
|
---|
| 503 | Added 'SHELL = /bin/sh' to Makefiles.
|
---|
| 504 | Compare file version to pdfVersionNum+0.0001 to avoid floating point
|
---|
| 505 | precision problems.
|
---|
| 506 | Added LDFLAGS to Makefiles.
|
---|
| 507 | Removed strip entirely from configure and Makefiles.
|
---|
| 508 | Fixed a bug in choosing the correct DCTStream color transform.
|
---|
| 509 |
|
---|
| 510 | 0.91 (2000-aug-14)
|
---|
| 511 | ------------------
|
---|
| 512 | Added TrueType font rendering, using FreeType.
|
---|
| 513 | Support for Chinese fonts (Type 0 fonts using the Adobe-GB1-2
|
---|
| 514 | character collection).
|
---|
| 515 | Decryption code is included with the main distribution (now that the
|
---|
| 516 | US export regulations are a little bit less irrational).
|
---|
| 517 | Added (very basic) support for generating PostScript with Japanese
|
---|
| 518 | fonts -- only tested with ghostscript so far.
|
---|
| 519 | Added support for generating EPS files (pdftops -eps).
|
---|
| 520 | Much-improved image filtering in xpdf (for downsampling and for
|
---|
| 521 | transforms other than 0/90/180/270-degree rotations).
|
---|
| 522 | Implemented a basic full-screen (presentation) mode (xpdf
|
---|
| 523 | -fullscreen). (There is currently no way to switch between window
|
---|
| 524 | and full-screen modes on the fly -- this will be fixed in a later
|
---|
| 525 | release.)
|
---|
| 526 | Added "reload" menu item.
|
---|
| 527 | Do a better job with anti-aliased Type 1 fonts on non-white
|
---|
| 528 | backgrounds.
|
---|
| 529 | Handle Lab color spaces.
|
---|
| 530 | Handle non-null user passwords.
|
---|
| 531 | Avoid security hole with tmpnam()/fopen() -- added openTempFile() in
|
---|
| 532 | goo/gfile.cc. [Thanks to Joseph S. Myers for pointing this out.]
|
---|
| 533 | Filter out quote marks (' and ") in URLs before running urlCommand to
|
---|
| 534 | avoid a potential security hole. [Thanks to Frank Doepper for
|
---|
| 535 | pointing this out.]
|
---|
| 536 | Fixed TrueColor detection to look at the complete list of available
|
---|
| 537 | visuals, not just the default visual.
|
---|
| 538 | In gfile.h, changed NAMLEN(dirent) macro to NAMLEN(d).
|
---|
| 539 | Removed copyright character from start-up banners.
|
---|
| 540 | In the open and save dialogs, if the open/save button is pressed with
|
---|
| 541 | no file name, the dialog is not canceled.
|
---|
| 542 | Added Xpm_CFLAGS to ltk/Makefile.
|
---|
| 543 | XOutputDev::updateLineAttrs was using dashLength before it was
|
---|
| 544 | defined.
|
---|
| 545 | In top-level Makefile.in, use INSTALL_PROGRAM instead of INSTALL.
|
---|
| 546 | In man page, recommend -q instead of -err in .mailcap.
|
---|
| 547 | Changes for GNOME / Bonobo support:
|
---|
| 548 | - Separated Stream classes into BaseStream and FilterStream trees.
|
---|
| 549 | - Got rid of all FileStream-specific stuff.
|
---|
| 550 | - Added a PDFDoc constructor that takes a BaseStream* instead of a
|
---|
| 551 | file name.
|
---|
| 552 | Allow newlines inside strings (Photoshop does this).
|
---|
| 553 | Don't require whitespace between tokens in consecutive content
|
---|
| 554 | streams (for pages that specify an array of streams).
|
---|
| 555 | Look at MissingWidth when constructing font character widths array.
|
---|
| 556 | Fixed a bug that caused incorrect PostScript output for images that
|
---|
| 557 | use 8-bit indexed color spaces with < 256 colors in the palette.
|
---|
| 558 | Handle case where embedded font file is bad (this was seg faulting).
|
---|
| 559 | Minor changes for Windows/pdftex.
|
---|
| 560 | Work around a bug in PDF files from the IBM patent server.
|
---|
| 561 | Fixed bugs in PostScript form generation: use pdfStartPage instead of
|
---|
| 562 | pdfSetup; problem with inline images.
|
---|
| 563 | Minor bug fix in FlateStream::loadFixedCodes().
|
---|
| 564 | Added %%DocumentMedia and %%PageMedia comments to the PostScript so
|
---|
| 565 | that gsview (a Windows frontend for ghostscript) gets the right
|
---|
| 566 | paper size.
|
---|
| 567 | Draw AcroForm fields that have appearance annotations.
|
---|
| 568 | Bounds check gray, CMYK, and RGB values (in GfxColor).
|
---|
| 569 | Moved the link border drawing code into Page (from PDFDoc).
|
---|
| 570 | Minor modifications for pdftohtml.
|
---|
| 571 | PSOutputDev: use the Type 3 font scaling kludge from XOutputDev.
|
---|
| 572 | Separation color spaces were handled incorrectly in images.
|
---|
| 573 | Fixed a bug with form bounding boxes.
|
---|
| 574 | Modified the t1lib support -- replace libt1x code with my own code.
|
---|
| 575 | Type 1 and TrueType fonts are now handled similarly, and clipping
|
---|
| 576 | works on Type 1 fonts.
|
---|
| 577 | Don't print copyright banner (xpdf); add -v switch to get copyright
|
---|
| 578 | and version info (all apps); get rid of -err switch (xpdf).
|
---|
| 579 | Automatically reload the PDF file if it has been changed, i.e., if the
|
---|
| 580 | modification time is different.
|
---|
| 581 | Fixed a memory (malloc size) bug in CCITTFaxStream.
|
---|
| 582 | Fixed two bugs in FontEncoding::hash() -- handle zero-length character
|
---|
| 583 | names (which were found in a (buggy?) PDF file), and handle
|
---|
| 584 | character names with high-bit-set characters (use unsigned ints).
|
---|
| 585 | Added PDFDoc::isLinearized() and corresponding code in pdfinfo.cc.
|
---|
| 586 | Handle files with an incorrect page count in the Pages dictionary
|
---|
| 587 | (FOP, from the Apache project produces a page count of 0).
|
---|
| 588 | Handle TrueType equivalents to the Base14 fonts (Arial, TimesNewRoman,
|
---|
| 589 | CourierNew) -- Adobe's tools use these names without embedding the
|
---|
| 590 | fonts.
|
---|
| 591 | Tweaked the Type 3 font sizing kludge.
|
---|
| 592 | Changed pdfimages (ImageOutputDev) so it doesn't output JPEG files for
|
---|
| 593 | 4-component color spaces, since these seem to confuse most image
|
---|
| 594 | viewers.
|
---|
| 595 | Added support for generating OPI comments (pdftops -opi).
|
---|
| 596 | In XOutputDev::drawImage() and drawImageMask(), check for images that
|
---|
| 597 | are completely off-page.
|
---|
| 598 | Use the provided alternate or a default (DeviceGray/RGB/CMYK) color
|
---|
| 599 | space for ICCBased color spaces.
|
---|
| 600 | Incorporated MacOS-specific code from Leonard Rosenthol.
|
---|
| 601 | Configure script switches to C++ for the strings.h/bstring.h test.
|
---|
| 602 | Gfx::opRestore() calls clearPath() to handle (apparently) buggy PDF
|
---|
| 603 | files produced by FreeHand.
|
---|
| 604 | The /Type field in most dictionaries is optional (PDF 1.3 change).
|
---|
| 605 | Move printCommands variable definition into Gfx.cc.
|
---|
| 606 | If page is smaller than paper, center the PostScript output.
|
---|
| 607 | Fix a minor bug in the SELECT_TAKES_INT detection in the configure
|
---|
| 608 | script.
|
---|
| 609 | TextOutputDev filters out control characters.
|
---|
| 610 | Changed enough occurrences of 'char *' to 'const char *' to keep gcc
|
---|
| 611 | 2.95 from barfing.
|
---|
| 612 | Support for Latin-2 and Latin-5 in pdftotext (however, this will only
|
---|
| 613 | work if the PDF file contains correct font encodings, which seems to
|
---|
| 614 | be rare).
|
---|
| 615 | TextOutputDev converts "eightoldstyle" to "eight", etc.
|
---|
| 616 | Don't use the return value from sprintf() -- most systems return the
|
---|
| 617 | length, but some return the string.
|
---|
| 618 | Minor fixes for SunOS 4.
|
---|
| 619 | Configure script looks for both select() and fd_set in sys/select.h.
|
---|
| 620 | Configure script checks for gethostbyname() in -lbsd (for LynxOS).
|
---|
| 621 | Fix missing closepath bug in PostScript output.
|
---|
| 622 | Change PostScript portrait/landscape mode selection so it only uses
|
---|
| 623 | landscape if the page width is greater than the paper width.
|
---|
| 624 | Tweaked the VMS code in makePathAbsolute().
|
---|
| 625 |
|
---|
| 626 | 0.91a (2000-oct-11)
|
---|
| 627 | -------------------
|
---|
| 628 | Implemented separable CMYK PostScript output (the -level1sep switch to
|
---|
| 629 | pdftops).
|
---|
| 630 | Implemented Pattern color spaces with tiling patterns (polygon fills
|
---|
| 631 | only).
|
---|
| 632 | Implemented Stamp annotations.
|
---|
| 633 | Implemented Named link actions.
|
---|
| 634 | Fixed a really dumb bug in the TrueColor code in SFont (which affects
|
---|
| 635 | both Type 1 and TrueType font rendering on 16-bit displays).
|
---|
| 636 | Rewrote the GfxColorSpace / GfxColor code.
|
---|
| 637 | Switched from djgppcfg to dj_make.bat (from Michael Richmond).
|
---|
| 638 | Bug in the Type 1 encoding parser -- couldn't handle lines of the form
|
---|
| 639 | 'dup NNN/name put' (with no space between the code and the name).
|
---|
| 640 | Fixed the mkstemp() test in configure.in -- switched from
|
---|
| 641 | AC_TRY_COMPILE to AC_TRY_LINK and added <unistd.h>.
|
---|
| 642 | Added DESTDIR to top-level Makefile.in.
|
---|
| 643 | Fixed an incorrect OPI comment in PSOutputDev.
|
---|
| 644 | Minor tweak to the CCITTFax code to avoid writing past the end of an
|
---|
| 645 | array on an invalid data stream.
|
---|
| 646 | Xpdf crashed if the user selected 'reload' when no document was
|
---|
| 647 | loaded.
|
---|
| 648 | Look for character names of the form "xx" (two hex digits with no
|
---|
| 649 | leading alphabetic char) and 'cNNN' (decimal digits with a leading
|
---|
| 650 | alphabetic char that happens to be a hex digit).
|
---|
| 651 | FlateStream didn't correctly handle zero-length streams.
|
---|
| 652 | Xref reconstruction didn't handle the case where the opening "<<"
|
---|
| 653 | immediately followed "trailer" with no intervening whitespace.
|
---|
| 654 | Fix the %%DocumentSuppliedResources comment in EPS output.
|
---|
| 655 | Scale annotations to fit their rectangles.
|
---|
| 656 | Added Stream::close() to handle cases (e.g., patterns) where a Stream
|
---|
| 657 | object is used multiple times before it is deleted.
|
---|
| 658 | Added the topLevel arg to Gfx::go() so it doesn't call out->dump() for
|
---|
| 659 | every pattern element (and form).
|
---|
| 660 | Rearranged the GfxResources class.
|
---|
| 661 | Clean up white space handling in Lexer.
|
---|
| 662 | Make the dpi parameter to PDFDoc::displayPage etc. a double - this
|
---|
| 663 | avoids margin gaps with fit-page and fit-width.
|
---|
| 664 | Fix a rounding problem in xpdf.cc that was causing the window to
|
---|
| 665 | sometimes be one pixel too small.
|
---|
| 666 | Fixed a minor bug in dealing with Base-14 TrueType font names.
|
---|
| 667 | Fixed Lab -> RGB color space conversion.
|
---|
| 668 | Added support for opacity values (from PDF 1.4) to GfxState and
|
---|
| 669 | OutputDev. [Thanks to Leonard Rosenthol.]
|
---|
| 670 | Implemented type 2 functions; rearranged the Function class
|
---|
| 671 | hierarchy.
|
---|
| 672 |
|
---|
| 673 | 0.91b (2000-oct-29)
|
---|
| 674 | -------------------
|
---|
| 675 | Print a warning about Type 3 fonts (XOutputDev, PSOutputDev).
|
---|
| 676 | Added the scroll lock behavior to 'n' and 'p' keys in xpdf.
|
---|
| 677 | Change FileStream buffer size to a #define'd constant.
|
---|
| 678 | Renamed Pattern to GfxPattern to avoid clashes with Windows and MacOS
|
---|
| 679 | types.
|
---|
| 680 | Added CNS (Big5) Chinese font support (CHINESE_CNS_SUPPORT); renamed
|
---|
| 681 | CHINESE_SUPPORT to CHINESE_GB_SUPPORT.
|
---|
| 682 |
|
---|
| 683 | 0.91c (2000-nov-19)
|
---|
| 684 | -------------------
|
---|
| 685 | Fix an endianness problem in the Type 1 font code which resulted in an
|
---|
| 686 | incorrect display with "-t1lib plain" on big-endian systems.
|
---|
| 687 | CCITTFax stream decoder will skip over extra zero bits at end of line,
|
---|
| 688 | even if EncodedByteAlign flag wasn't set.
|
---|
| 689 | Added Big5 support to pdftotext (with CHINESE_CNS_SUPPORT enabled).
|
---|
| 690 | Fixed a typo in the CNS/Big5 encoding translation table.
|
---|
| 691 | Change the form code in PSOutputDev to store images in arrays of
|
---|
| 692 | strings.
|
---|
| 693 | The xref reconstruction (for damaged files) now also looks for
|
---|
| 694 | 'endstream' tags, and the parser uses this information when setting
|
---|
| 695 | up stream objects.
|
---|
| 696 | In pdfinfo, convert Unicode chars in the 00xx range into 8-bit chars;
|
---|
| 697 | print a warning if there are any other Unicode chars.
|
---|
| 698 |
|
---|
| 699 | 0.92 (2000-dec-03)
|
---|
| 700 | ------------------
|
---|
| 701 | Fixed %%BeginResource comment (for xpdf procset) in PostScript
|
---|
| 702 | output.
|
---|
| 703 | Added "-title" switch and "xpdf.title" resource to set the window
|
---|
| 704 | title.
|
---|
| 705 | Check for <freetype.h> in addition to <freetype/freetype.h>.
|
---|
| 706 | Upgraded the configure script to smr_macros 0.2.4 - this should fix a
|
---|
| 707 | bug where configure wasn't correctly finding t1lib.
|
---|
| 708 |
|
---|
| 709 | 0.92a (2000-dec-17)
|
---|
| 710 | -------------------
|
---|
| 711 | Added 'extern "C" { ... }' in various places for ANSI C++ compliance.
|
---|
| 712 | Tweaked the code that figures out DPI for fit-to-page and fit-to-width
|
---|
| 713 | modes.
|
---|
| 714 | Fixed the image transformation code in XOutputDev -- no more missing
|
---|
| 715 | lines.
|
---|
| 716 | Implemented color key image masking in XOutputDev.
|
---|
| 717 |
|
---|
| 718 | 0.92b (2001-jan-07)
|
---|
| 719 | -------------------
|
---|
| 720 | Fixed a bug in the error-checking code in the Separation/DeviceN color
|
---|
| 721 | space parsing functions. [Thanks to Lidia Mirkin.]
|
---|
| 722 | Added wheel mouse support (mouse buttons 4 and 5). [Thanks to
|
---|
| 723 | Thorsten Schreiner.]
|
---|
| 724 | Added preliminary support for FreeType 2 (disabled by default).
|
---|
| 725 |
|
---|
| 726 | 0.92c (2001-jun-04)
|
---|
| 727 | -------------------
|
---|
| 728 | Fixed a bug in the new image transformation code.
|
---|
| 729 | Look for character names of the form "<letter><digit><digit>", instead
|
---|
| 730 | of looking for names beginning with a few specific letters.
|
---|
| 731 | T1FontFile::T1FontFile wasn't initializing vars, and ~T1FontFile
|
---|
| 732 | wasn't checking before calling T1_DeleteFont -- this caused crashes
|
---|
| 733 | if it tried to open a nonexistent font file.
|
---|
| 734 | Catalog::Catalog didn't set baseURI to NULL early enough.
|
---|
| 735 | Tweak the check for strings.h in the configure script.
|
---|
| 736 | Yet another fix for the image rotation code in XOutputDev --
|
---|
| 737 | off-by-one problem when upsampling.
|
---|
| 738 | Handle Type 1/1C encodings when using FreeType 2.
|
---|
| 739 | Allow FreeType2 to render user-supplied Type 1 base fonts.
|
---|
| 740 | Opening a new file from full-screen mode tried to scroll.
|
---|
| 741 | Fixed a bug in GfxFont constructor (missing check for NULL base font
|
---|
| 742 | name).
|
---|
| 743 | Don't crash if a Type 1 font's FontBBox is non-integer.
|
---|
| 744 | Pdfinfo prints page size.
|
---|
| 745 | Tweak for the alpha hack in T1Font/TTFont: sample the middle pixel
|
---|
| 746 | instead of the top-left pixel.
|
---|
| 747 | Automatically activate the text input widget in the find window.
|
---|
| 748 | Changed a Japanese char code mapping in XOutputDev and TextOutputDev:
|
---|
| 749 | period was being incorrectly mapped to small circle (end-of-sentence
|
---|
| 750 | character).
|
---|
| 751 | Add the 0/+/-/z/w key bindings to control the zoom setting.
|
---|
| 752 | Fixed ImageOutputDev (pdfimages) to correctly handle inline image
|
---|
| 753 | masks.
|
---|
| 754 | Extract ascent/descent info from font descriptor.
|
---|
| 755 |
|
---|
| 756 | 0.92d (2001-jun-26)
|
---|
| 757 | -------------------
|
---|
| 758 | Embed TrueType fonts in PostScript output. (Added a "-noembtt" flag
|
---|
| 759 | to pdftops.)
|
---|
| 760 | Extract encoding from TrueType fonts.
|
---|
| 761 | Moved Function classes to a separate file (Function.h/cc).
|
---|
| 762 | Implemented multi-dimensional sampled Functions.
|
---|
| 763 | Implemented Type 4 (PostScript calculator) Functions.
|
---|
| 764 | For Type 0 fonts, FontDescriptor is in descendant font, not parent.
|
---|
| 765 | [Thanks to Lidia Mirkin.]
|
---|
| 766 | Added the "-htmlmeta" option to pdftotext.
|
---|
| 767 | In TextOutputDev, when computing the number of blank lines to insert,
|
---|
| 768 | do a sanity check on the result.
|
---|
| 769 | If both FlateDecode and some other filter (e.g., DCTDecode) were
|
---|
| 770 | applied to an image stream, getPSFilter() crashed instead of just
|
---|
| 771 | returning NULL.
|
---|
| 772 | Handle the /Identity function.
|
---|
| 773 |
|
---|
| 774 | 0.92e (2001-aug-23)
|
---|
| 775 | -------------------
|
---|
| 776 | Widths in font dict should override built-in font widths.
|
---|
| 777 | Changed "rotate left/right" menu items to "rotate
|
---|
| 778 | clockwise/counterclockwise".
|
---|
| 779 | The link parsing code choked if the Border array was incorrect (too
|
---|
| 780 | short).
|
---|
| 781 | Modified PSOutputDev to output CMYK for fill/stroke colors.
|
---|
| 782 |
|
---|
| 783 | 0.93 (2001-oct-25)
|
---|
| 784 | ------------------
|
---|
| 785 | Implement PDF 1.4 (128-bit) decryption.
|
---|
| 786 | Bump supported PDF version number to 1.4.
|
---|
| 787 | Text output for Simplified Chinese. [Thanks to Cheung Siu Fai.]
|
---|
| 788 | Read an app-defaults file for Xpdf.
|
---|
| 789 | Read a system-wide config file (<prefix>/etc/xpdfrc) if ~/.xpdfrc
|
---|
| 790 | doesn't exist.
|
---|
| 791 | Accept and verify owner password; if correct, allow all actions.
|
---|
| 792 | Added a "-level2sep" option to pdftops to generate Level 2 separable
|
---|
| 793 | PostScript. The PostScript separation convention operators are used
|
---|
| 794 | to handle custom (spot) colors. [Thanks to Thomas Freitag for help
|
---|
| 795 | on this.]
|
---|
| 796 | Add support for FreeType 2 to the configure script. Warning: this
|
---|
| 797 | requires FT 2.0.5 or newer.
|
---|
| 798 | Fixed the bounding rectangle overlap test in the disconnected subpath
|
---|
| 799 | fill hack in XOutputDev.
|
---|
| 800 | Stupid typo in font name table in PSOutputDev.
|
---|
| 801 | Changing the zoom setting with a keyboard shortcut didn't update the
|
---|
| 802 | displayed setting.
|
---|
| 803 | Modified the mouse wheel support and added the second wheel (mouse
|
---|
| 804 | buttons 6 and 7). [Thanks to Michal Pasternak.]
|
---|
| 805 | Character and word spacing is affected by horizontal scaling (display
|
---|
| 806 | and PS output). [Thanks to Eddy Ng.]
|
---|
| 807 | Rotation specified by the text matrix, character spacing, and
|
---|
| 808 | horizontal scaling interacted incorrectly (display and PS output).
|
---|
| 809 | Some broken Type 1/1C fonts have a zero BBox -- kludge around this by
|
---|
| 810 | assuming a largeish BBox.
|
---|
| 811 | Handle PDF files with an incorrect (too small) xref table size.
|
---|
| 812 | Allow "-?" and "--help" as aliases for "-h" (all apps).
|
---|
| 813 | Correctly handle unescaped parens in strings in Lexer.
|
---|
| 814 | Fixed a bug in LTK where a menu got posted multiple times if you right
|
---|
| 815 | clicked while a page was being rendered.
|
---|
| 816 | Removed a comma inside a string in configure.in.
|
---|
| 817 | Kludge around broken PDF files that use char 32 but encode it as
|
---|
| 818 | .notdef instead of space.
|
---|
| 819 | Clean up various compiler warnings: use constructor args like "fooA"
|
---|
| 820 | if there is a field named "foo". Everything now compiles cleanly
|
---|
| 821 | under gcc 2.91.66, 2.95.2, and 3.0.1.
|
---|
| 822 | Page objects now read all of the page rectangles (MediaBox, CropBox,
|
---|
| 823 | BleedBox, TrimBox, ArtBox), as requested by the pdfTeX folks.
|
---|
| 824 | Added a new PDFRectangle struct to hold these.
|
---|
| 825 | Use XOutputDev's Type 3 font size hack in TextOutputDev too, so it
|
---|
| 826 | does a little better job of extracting text in Type 3 fonts.
|
---|
| 827 | Modify pdfimages to write one-bit images as PBM files.
|
---|
| 828 | Work around a bug in cygwin's implementation of fseek.
|
---|
| 829 |
|
---|
| 830 | 0.93a (2001-nov-21)
|
---|
| 831 | -------------------
|
---|
| 832 | Implemented the sh (shaded fill) operator for the axial shading type.
|
---|
| 833 | Minor fixes to avoid compiler warnings.
|
---|
| 834 | Cleaned up global variables -- moved many into instance vars and
|
---|
| 835 | function args.
|
---|
| 836 | Minor fixes for OS/2.
|
---|
| 837 | Fix the system config file path for VMS.
|
---|
| 838 | Fix an uninitialized var in XOutputDev that caused crashes on Alphas.
|
---|
| 839 | Don't incrementally update the display in full-screen mode.
|
---|
| 840 | For Type 1/1C fonts, use the FontBBox from the PDF FontDescriptor
|
---|
| 841 | (instead of the one in the font file) if present -- this avoids
|
---|
| 842 | problems with fonts that have non-standard FontMatrixes.
|
---|
| 843 | Add the Euro character to WinAnsiEncoding.
|
---|
| 844 | Track the bounding box of the clip region to make rendering patterns
|
---|
| 845 | more efficient.
|
---|
| 846 | Fix openTempFile() for Win32.
|
---|
| 847 |
|
---|
| 848 | 0.93b (2001-dec-11)
|
---|
| 849 | -------------------
|
---|
| 850 | Added a duplex option to PSOutputDev and a -duplex switch to pdftops.
|
---|
| 851 | Added XRef::PDFgetDocInfoNF() for pdftex project.
|
---|
| 852 | Updated the VMS build script.
|
---|
| 853 |
|
---|
| 854 | 0.93c (2001-dec-12)
|
---|
| 855 | -------------------
|
---|
| 856 | Completely rewrote the code that handles font encodings:
|
---|
| 857 | - everything is Unicode-based
|
---|
| 858 | - 16-bit fonts are handled much more cleanly
|
---|
| 859 | - text output encoding can be set more flexibly
|
---|
| 860 | New .xpdfrc config files.
|
---|
| 861 |
|
---|
| 862 | 1.00 (2002-feb-01)
|
---|
| 863 | ------------------
|
---|
| 864 | More work on the font encoding rewrite:
|
---|
| 865 | - use the ToUnicode font dict entry
|
---|
| 866 | - pdfinfo and pdftotext (with '-htmlmeta') convert info strings to
|
---|
| 867 | the selected text encoding
|
---|
| 868 | Added key bindings for forward ('v') and backward ('b').
|
---|
| 869 | Added the pdffonts program which lists the fonts used in a PDF file.
|
---|
| 870 | Fixed several problems in the TrueType font embedding code (for
|
---|
| 871 | PostScript output).
|
---|
| 872 | Accept named destination on command line.
|
---|
| 873 | Added several new items to pdfinfo: file size, PDF version, tagged
|
---|
| 874 | (yes or no), XML metadata (with the -meta option).
|
---|
| 875 | Pdftops didn't get the portrait/landscape setting correct for PDF
|
---|
| 876 | files with rotated pages.
|
---|
| 877 | The TrueTypeFontFile class (including the Type 42 converter) now
|
---|
| 878 | understands cmap format 6.
|
---|
| 879 | Improved the "about" window -- mention the GPL, add a list of key
|
---|
| 880 | bindings.
|
---|
| 881 | Added Zcaron and zcaron characters to WinAnsiEncoding.
|
---|
| 882 | The '0' keyboard shortcut didn't update the zoom popup menu.
|
---|
| 883 | Handle the complete list of alternate names for the Base14 fonts.
|
---|
| 884 | Fixed substitute font scaling in XOutputDev - scale only the width,
|
---|
| 885 | not the height.
|
---|
| 886 | Implemented stitching (type 3) functions.
|
---|
| 887 | Handle the case of moveto/closepath/clip, which defines an empty
|
---|
| 888 | clipping region.
|
---|
| 889 | Move dependences into separate Makefile.dep files; get rid of the
|
---|
| 890 | distdepend target.
|
---|
| 891 | Move all of the configure-script-generated -D options out of the
|
---|
| 892 | Makefiles and into a top-level .h file (aconf.h).
|
---|
| 893 | Cleaned up the FreeType 1/2 detection code in the configure script.
|
---|
| 894 | Pdfinfo prints dates in a more readable format.
|
---|
| 895 | Fixed a bug in the Paeth image predictor.
|
---|
| 896 | Handle annotations with multiple states.
|
---|
| 897 | Another workaround for buggy X servers: clip points that are way out
|
---|
| 898 | of bounds.
|
---|
| 899 | Added libpaper support (for Debian).
|
---|
| 900 | Generate PostScript DSC resource comments for PS (not just EPS)
|
---|
| 901 | files.
|
---|
| 902 | The save and restore (q/Q) operators shouldn't save/restore the path.
|
---|
| 903 | Performance optimization: disable pattern drawing in TextOutputDev.
|
---|
| 904 |
|
---|
| 905 | 1.00a (2002-feb-25)
|
---|
| 906 | -------------------
|
---|
| 907 | Added an optimized special case for one-bit images in XOutputDev.
|
---|
| 908 | Implemented CID TrueType font embedding; added a psEmbedCIDTrueType
|
---|
| 909 | option.
|
---|
| 910 | The initialZoom X resource was broken.
|
---|
| 911 | The reverse MacRoman encoding should return 32 for "space" (not 202,
|
---|
| 912 | which is an alternate encoding).
|
---|
| 913 | Tweaks to the FreeType 2 support: only disable hinting if the bytecode
|
---|
| 914 | interpreter is disabled (i.e., disable autohinting but not bytecode
|
---|
| 915 | hinting); add some padding to the glyph cache for CJK fonts.
|
---|
| 916 | Added level3 and level3Sep options for the psLevel setting and
|
---|
| 917 | corresponding -level3 and -level3Sep options to pdftops.
|
---|
| 918 | Added a -level2 option to pdftops for consistency.
|
---|
| 919 | Avoid a divide by zero in pdftotext. [Thanks to William Bader.]
|
---|
| 920 | Added a Greek language support package. [Thanks to Alexandros
|
---|
| 921 | Diamantidis and Maria Adaloglou.]
|
---|
| 922 | Don't bother trying to extract a "builtin" encoding from a TrueType
|
---|
| 923 | font.
|
---|
| 924 | Accept either a page number or a page reference in a link
|
---|
| 925 | destination.
|
---|
| 926 | Update the fontFixedWidth flag in GfxFont after reading the char
|
---|
| 927 | widths (used by the Acorn RiscOS port).
|
---|
| 928 | Removed yet another (illegal but not caught by gcc) class specified
|
---|
| 929 | from a .h file.
|
---|
| 930 | Avoid using snprintf - it's not available everywhere.
|
---|
| 931 | Improved the CMYK->RGB transform.
|
---|
| 932 | Use mkstemps where available.
|
---|
| 933 |
|
---|
| 934 | 1.01 (2002-may-20)
|
---|
| 935 | ------------------
|
---|
| 936 | Implemented Type 3 fonts.
|
---|
| 937 | Implemented PostScript CID font embedding; added a
|
---|
| 938 | psEmbedCIDPostScriptFonts option.
|
---|
| 939 | Implemented PostScript 16-bit font substitution; added psNamedFont16
|
---|
| 940 | and psFont16 options.
|
---|
| 941 | Moved the initialZoom setting from X resources to the xpdfrc file.
|
---|
| 942 | Implemented the radial shading type in the sh (shaded fill) operator.
|
---|
| 943 | [Thanks to Mike Sweet.]
|
---|
| 944 | Added an 'include' command to the xpdfrc format.
|
---|
| 945 | Added the displayNamedCIDFontX option so different fonts can be used
|
---|
| 946 | within one character collection.
|
---|
| 947 | Added a simple reverse video mode (-rv switch, xpdf.reverseVideo
|
---|
| 948 | resource).
|
---|
| 949 | Implemented stroked text in XOutputDev (with t1lib and FreeType2).
|
---|
| 950 | [Thanks to Leonard Rosenthol.]
|
---|
| 951 | Implemented stroked text in PSOutputDev.
|
---|
| 952 | Added a built-in Unicode map for UCS-2.
|
---|
| 953 | New key binding in xpdf: 'g' activates the page number text field.
|
---|
| 954 | PSOutputDev will now embed external TrueType fonts in addition to
|
---|
| 955 | external Type 1 fonts.
|
---|
| 956 | The psEmbedType1Fonts and psEmbedTrueTypeFonts options were missing
|
---|
| 957 | the "Fonts" suffix.
|
---|
| 958 | Documentation in xpdf.1 for -freetype option was wrong.
|
---|
| 959 | Added the Big5ascii Unicode map to the Chinese-traditional support
|
---|
| 960 | package (maps 7-bit ASCII straight through). [Thanks to Lawrence
|
---|
| 961 | Lai.]
|
---|
| 962 | Modified the EUC-CN and EUC-JP encodings to pass 7-bit ASCII straight
|
---|
| 963 | through. [Thanks to Lawrence Lai.]
|
---|
| 964 | Avoid a divide by zero in XOutputDev. [Thanks to Simon Burge.]
|
---|
| 965 | Remove old code in openTempFile that removed an extension from the
|
---|
| 966 | name returned by tmpnam.
|
---|
| 967 | Tweak the scrolling behavior when switching pages. [Thanks to Case
|
---|
| 968 | Jones.]
|
---|
| 969 | In the code that guesses character names (for font subsets), also
|
---|
| 970 | handle names of the form 'ABnnn'. [Thanks to Colin Granville.]
|
---|
| 971 | Fix the transform code for annotations.
|
---|
| 972 | Improved the CMap file parser to handle more general PostScript
|
---|
| 973 | lexical conventions.
|
---|
| 974 | Added '-enc' option to pdfinfo.
|
---|
| 975 | Added the small caps and oldstyle numbers from Adobe's Unicode
|
---|
| 976 | corporate use area to the Latin1 and ASCII7 Unicode maps.
|
---|
| 977 | The code in TextOutputDev that guesses Type 3 font size could generate
|
---|
| 978 | a zero size, which resulted in div-by-zero errors.
|
---|
| 979 | Various tools (including Adobe's) occasionally embed Type 1 fonts but
|
---|
| 980 | label them Type 1C - so check for a '%!' at the start.
|
---|
| 981 | Some tools embed Type 1C fonts with an extra whitespace char at the
|
---|
| 982 | beginning - just skip over it.
|
---|
| 983 | Fixed a typo in the Simplified Chinese add-to-xpdfrc file.
|
---|
| 984 | Updates to dj_make.bat and the djgpp build instructions.
|
---|
| 985 | Added a Turkish language support package.
|
---|
| 986 | Updated VMS build scripts. [Thanks to Martin Zinser.]
|
---|
| 987 | Modify the incremental display update code to redraw less often if
|
---|
| 988 | most of the commands are vector graphics, as opposed to text and
|
---|
| 989 | images.
|
---|
| 990 | Tweak the Type 1 font bbox code to look at the bboxes in both the PDF
|
---|
| 991 | font object and the embedded font file.
|
---|
| 992 | Fixed the ETenms-B5-H CMap file (for traditional Chinese) to map the
|
---|
| 993 | Latin characters to their proportional versions.
|
---|
| 994 | Added an optional displayCIDFontX entry for one of the Arphic TrueType
|
---|
| 995 | fonts in the traditional Chinese 'add-to-xpdfrc' file.
|
---|
| 996 | Remove leading '-' on include statements in Makefiles.
|
---|
| 997 | Added psASCIIHex parameter.
|
---|
| 998 | Added the GBK Unicode map to the simplified Chinese language pack.
|
---|
| 999 | Pdftotext now opens the text file in binary mode to avoid Microsoft's
|
---|
| 1000 | annoying automatic end-of-line translation stuff.
|
---|
| 1001 | Added an executeCommand function in goo/gfile.cc. [Thanks to Mikhail
|
---|
| 1002 | Kruk.]
|
---|
| 1003 | The %ALDImagePosition OPI comment was wrong if the page was scaled to
|
---|
| 1004 | a different paper size.
|
---|
| 1005 | The OPI code was saving the default transform matrix before calling
|
---|
| 1006 | setpagedevice, which can change the matrix.
|
---|
| 1007 | Fixed a crash when an inline image dictionary contains garbage.
|
---|
| 1008 | Upgraded to autoconf 2.53.
|
---|
| 1009 | Use unsigned int file offsets, to allow access to PDF files in the 2-4
|
---|
| 1010 | GB size range; use fseek64/ftell64 if available.
|
---|
| 1011 | Fixed two floating point exception cases that came up with broken PDF
|
---|
| 1012 | files.
|
---|
| 1013 | Avoid a crash when printing an error message regarding an unnamed
|
---|
| 1014 | font.
|
---|
| 1015 | Default link border width should be 1. [Thanks to Michael Pfeiffer.]
|
---|
| 1016 | Minor tweak to build with FreeType 2.1.0.
|
---|
| 1017 | Handle "weird" characters in PostScript font names.
|
---|
| 1018 | PSOutputDev now handles PostScript XObjects.
|
---|
| 1019 | Added several more page attributes for the pdftex project.
|
---|
| 1020 | Transferred the copyright to Glyph & Cog, LLC.
|
---|
| 1021 |
|
---|
| 1022 | 2.00 (2002-nov-04)
|
---|
| 1023 | ------------------
|
---|
| 1024 | Switched to the Motif toolkit.
|
---|
| 1025 | Support multiple open documents (in separate windows).
|
---|
| 1026 | Added document outlines to the viewer.
|
---|
| 1027 | Modified the text extraction (placement) algorithm.
|
---|
| 1028 | Implemented the JBIG2 decoder.
|
---|
| 1029 | Added a Latin2 language support package.
|
---|
| 1030 | Added support for movie annotations.
|
---|
| 1031 | Switched back to native LZW decompression code.
|
---|
| 1032 | Text extraction from Type 3 fonts was (partly) broken.
|
---|
| 1033 | The owner password checking code was missing a step in the case of
|
---|
| 1034 | 128-bit encryption.
|
---|
| 1035 | Added the 'printCommands' option to the xpdfrc file.
|
---|
| 1036 | Added key binding for '?' to bring up the about/help dialog.
|
---|
| 1037 | In TextOutputDev, ignore any text that's outside the page bounding
|
---|
| 1038 | box.
|
---|
| 1039 | Text extraction throws away "tiny" characters after the first 20000
|
---|
| 1040 | per page, to avoid really slow runtimes with PDF files that use
|
---|
| 1041 | special fonts to do shading or cross-hatching; added the
|
---|
| 1042 | 'textKeepTinyChars' option to disable this behavior.
|
---|
| 1043 | Text extraction discards duplicated text (fake boldface, shadow
|
---|
| 1044 | effects).
|
---|
| 1045 | Added ctrl-F as a key binding for find.
|
---|
| 1046 | Added a "find next" function, bound to ctrl-G.
|
---|
| 1047 | Added ctrl-P as a key binding for print.
|
---|
| 1048 | Modified the DCT decoder to handle progressive and non-interleaved
|
---|
| 1049 | JPEG streams.
|
---|
| 1050 | Added key bindings for ctrl-Home and ctrl-End.
|
---|
| 1051 | Allow the initialZoom setting to be made in either the xpdfrc file or
|
---|
| 1052 | as an X resource.
|
---|
| 1053 | Added a Hebrew language support package. [Thanks to Roy Arav.]
|
---|
| 1054 | The "make distclean" target now creates (empty) Makefile.dep files in
|
---|
| 1055 | the three subdirectories.
|
---|
| 1056 | Initialize XRef::ownerPasswordOk.
|
---|
| 1057 | Correctly handle stroking of Type 3 fonts in PSOutputDev.
|
---|
| 1058 | Generate correct PostScript for fonts with "weird" character names
|
---|
| 1059 | (e.g., "(").
|
---|
| 1060 | Generate correct PostScript for images using Indexed color spaces with
|
---|
| 1061 | DeviceN base color spaces.
|
---|
| 1062 | Added lowercase Roman numerals to ISO-2022-CN.unicodeMap (simplified
|
---|
| 1063 | Chinese support package).
|
---|
| 1064 | Tweak the image scaling code to better handle flipped (top-bottom
|
---|
| 1065 | and/or left-right) images.
|
---|
| 1066 | Generate correct PostScript code for inline images and images in Type
|
---|
| 1067 | 3 fonts which are too large for a single PS string.
|
---|
| 1068 | Correctly handle indexed color spaces whose base color spaces have
|
---|
| 1069 | component ranges other than [0,1].
|
---|
| 1070 | Optimized the DCT decoder.
|
---|
| 1071 | Fixed mistakes in the list of key bindings in the about/help dialog.
|
---|
| 1072 | Optimized the Flate decoder.
|
---|
| 1073 | Add literal names for punctuation and digits to the Unicode name
|
---|
| 1074 | table.
|
---|
| 1075 | Cygwin's popen wants mode "r", not "rb".
|
---|
| 1076 | Fixed a bug in the Type 4 function parser (the "if" operator wasn't
|
---|
| 1077 | parsed correctly).
|
---|
| 1078 | Fix a bug in PS output for TrueType fonts with no PDF encoding.
|
---|
| 1079 | Make the bbox size in FTFont more liberal (to avoid problems with
|
---|
| 1080 | fonts that have incorrect bboxes).
|
---|
| 1081 | Reverse the colors in PBM files generated by pdfimages, so the common
|
---|
| 1082 | case (an image mask filled with black) comes out correct.
|
---|
| 1083 | Add fseeko/ftello support which is basically identical to
|
---|
| 1084 | fseek64/ftell64. [Thanks to Nassib Nassar.]
|
---|
| 1085 | Modified column assignment in text extractor to account for characters
|
---|
| 1086 | that convert to multiple characters in the output encoding.
|
---|
| 1087 | Fix TrueType fonts which have an incorrect cmap table length.
|
---|
| 1088 | Work around a pragma bug in the version of gcc that ships with MacOS X
|
---|
| 1089 | 10.2. [Thanks to Frank Siegert and Andrew Stone.]
|
---|
| 1090 | Fix a problem that was causing an infinite loop when a damaged content
|
---|
| 1091 | stream contains an 'ID' command inside a dictionary.
|
---|
| 1092 | Handle the case where systempapername() returns NULL (libpaper
|
---|
| 1093 | support).
|
---|
| 1094 | Handle fonts which are defined directly in the font resource
|
---|
| 1095 | dictionary rather than as separate objects.
|
---|
| 1096 | Track process colors in Level 1 separable PostScript.
|
---|
| 1097 | Pdfinfo now checks the return value from mktime to avoid seg faults in
|
---|
| 1098 | flakey strftime implementations.
|
---|
| 1099 | If duplex is not enabled in PostScript output, leave the duplex
|
---|
| 1100 | setting alone, allowing the spooler to insert its own setting.
|
---|
| 1101 | Added three missing fclose calls.
|
---|
| 1102 | Change the default encoding for TrueType fonts (used when the PDF file
|
---|
| 1103 | doesn't specify an encoding) from MacRomanEncoding to
|
---|
| 1104 | WinAnsiEncoding.
|
---|
| 1105 | Move X_CFLAGS to the end of the list in CXXFLAGS (in Makefile.in) to
|
---|
| 1106 | avoid some of the FreeType2 include path problems.
|
---|
| 1107 | Fixed an obscure bug in the LZW decoder. [Thanks to Martin
|
---|
| 1108 | Schroeder.]
|
---|
| 1109 | Fixed a bug in decryption when using the newer (PDF 1.4) algorithm
|
---|
| 1110 | with shorter-than-128-bit keys.
|
---|
| 1111 | Minor optimization for image data streams: the ImageStream class can
|
---|
| 1112 | return an entire buffered line.
|
---|
| 1113 |
|
---|
| 1114 | 2.01 (2002-dec-05)
|
---|
| 1115 | ------------------
|
---|
| 1116 | Redesigned the text extraction process:
|
---|
| 1117 | - process the text into "reading order"
|
---|
| 1118 | - added a "-layout" flag to pdftotext to switch back to the old
|
---|
| 1119 | style, where physical layout is maintained
|
---|
| 1120 | - use of the "-raw" flag is no longer recommended
|
---|
| 1121 | Added the -reload option for xpdf (in remote mode).
|
---|
| 1122 | Added support for external CID fonts; added the displayCIDFontT1 and
|
---|
| 1123 | displayNamedCIDFontT1 commands to the xpdfrc file.
|
---|
| 1124 | Handle the case of moveto/newpath/clip, which defines an empty
|
---|
| 1125 | clipping region (just like moveto/closepath/clip).
|
---|
| 1126 | Accept XYZ link destinations with missing array elements.
|
---|
| 1127 | Fix some problems with state save/restore triggered by Type 3 fonts
|
---|
| 1128 | that reference other fonts.
|
---|
| 1129 | Accept bogus font names based on "Symbol": Symbol,{Bold,Italic,
|
---|
| 1130 | BoldItalic}.
|
---|
| 1131 | Fixed color and font resource names in the xpdf man page.
|
---|
| 1132 | Was using delete instead of gfree in OutlineItem::~OutlineItem.
|
---|
| 1133 | Set the busy cursor in the find dialog while searching.
|
---|
| 1134 | Map variants of the copyright, trademark, and registered trademark
|
---|
| 1135 | symbols to the proper Unicode codes, not to Adobe's corporate use
|
---|
| 1136 | area codes.
|
---|
| 1137 | Fixed a floating point exception bug in TextOutputDev (check for a
|
---|
| 1138 | too-small denominator).
|
---|
| 1139 | Fixed a typo in TextOutputDev, in the code that generating blank lines
|
---|
| 1140 | to add vertical whitespace.
|
---|
| 1141 | Config files whose last line didn't end with a LF (or CR+LF) weren't
|
---|
| 1142 | being handled correctly.
|
---|
| 1143 | The code that handled CIDToGIDMaps in Type 2 CIDFonts was broken.
|
---|
| 1144 | Check the per-glyph bounding box in Type 3 fonts, and don't try to
|
---|
| 1145 | cache glyphs with bogus bboxes.
|
---|
| 1146 | Allow ToUnicode CMaps to use fewer than four hex digits in the Unicode
|
---|
| 1147 | char indexes.
|
---|
| 1148 | Added multithreading protection to the GlobalParams class.
|
---|
| 1149 | Fixed a bug in end-of-stream detection with the TIFF predictor.
|
---|
| 1150 | Added some characters to MacRomanEncoding to match up with Apple's
|
---|
| 1151 | definition.
|
---|
| 1152 |
|
---|
| 1153 | 2.02 (2003-mar-24)
|
---|
| 1154 | ------------------
|
---|
| 1155 | Rewrote the text extractor code that assembles words into lines to
|
---|
| 1156 | better handle vertically overlapping lines.
|
---|
| 1157 | Add the "match" option for paper size (in PostScript output).
|
---|
| 1158 | Added support for external 16-bit TrueType fonts; added the
|
---|
| 1159 | displayCIDFontTT and displayNamedCIDFontTT commands to the xpdfrc
|
---|
| 1160 | file.
|
---|
| 1161 | Added an Arabic language support package.
|
---|
| 1162 | Added the Windows-1255 encoding to the Hebrew language package.
|
---|
| 1163 | A missing NULL check was causing a crash when closing the file in a
|
---|
| 1164 | single window (which clears out the window, but leaves it open).
|
---|
| 1165 | Deal with TrueType fonts whose glyph data is out of order - this
|
---|
| 1166 | affected both FreeType rasterization and PostScript generation.
|
---|
| 1167 | Munge font names in PSOutputDev to avoid names that are problematic
|
---|
| 1168 | for ghostscript because they start with an out-of-limits number
|
---|
| 1169 | (e.g., 1e999foo).
|
---|
| 1170 | Modify the TrueType font encoding deciphering algorithm in yet another
|
---|
| 1171 | attempt to match up with Acrobat's behavior.
|
---|
| 1172 | Bounds check the indexHigh value in indexed color spaces.
|
---|
| 1173 | The text extractor no longer bothers trying to get an average
|
---|
| 1174 | character width for Type 3 fonts, since it generally doesn't work
|
---|
| 1175 | very well (because Type 3 metrics are unreliable).
|
---|
| 1176 | Don't crash if the user hits ctrl-G ("find again") before doing a
|
---|
| 1177 | find.
|
---|
| 1178 | Set the button pixmap foreground color correctly.
|
---|
| 1179 | Handle text drawn backward on 180 degree rotated pages.
|
---|
| 1180 | Added a magic call to XtUngrabButton after calling XmCreatePopupMenu
|
---|
| 1181 | which appears to prevent some very odd problems (idea taken from the
|
---|
| 1182 | DDD source code).
|
---|
| 1183 | Fix the MacOS X fix (needed to include <AvailabilityMacros.h>).
|
---|
| 1184 | Fixed a bunch of Motif 1.x / X11R5 incompatibilities. [Thanks to
|
---|
| 1185 | William Bader and Albert Chin-A-Young.]
|
---|
| 1186 | Fixed various bugs in previously untested code in the JBIG2 decoder.
|
---|
| 1187 | Modify the XPDFCore destructor to avoid a bogus warning message from
|
---|
| 1188 | OpenMotif 2.2.
|
---|
| 1189 | Modified the Type 1C font parser to do proper bounds checking.
|
---|
| 1190 | Fixed the bounds checking in the TrueType font parser.
|
---|
| 1191 | Text extractor shouldn't do block merging in physical layout mode.
|
---|
| 1192 | Fixed a problem in PSOutputDev in level2sep mode with images in a
|
---|
| 1193 | Separation color space and with a non-default Decode array.
|
---|
| 1194 | Text extraction with "-raw" was concatenating lines from the bottom of
|
---|
| 1195 | one column and the top of the next.
|
---|
| 1196 | Handle Type 1C subroutines in the font converters.
|
---|
| 1197 | Correctly handle progressive JPEG images whose scans are slightly
|
---|
| 1198 | different sizes (e.g., the Y scan rounds up to a multiple of 8
|
---|
| 1199 | pixels and the Cb/Cr scans round up to 16 pixels).
|
---|
| 1200 | Avoid a potential divide-by-zero problem in TextOutputDev.
|
---|
| 1201 | Modified the T1Font and FTFont modules to correctly handle glyphs that
|
---|
| 1202 | are larger than the font's claimed bounding box.
|
---|
| 1203 | Tweak dupMaxDeltaX parameter in TextOutputDev to avoid triggering on
|
---|
| 1204 | double characters.
|
---|
| 1205 | Improved detection in pdfinfo for ISO paper sizes. [Thanks to Hartmut
|
---|
| 1206 | Henkel.]
|
---|
| 1207 | Xpdf wasn't responding to the TARGETS atom, which prevented pasting
|
---|
| 1208 | the selection into various applications. [Thanks to Phillip Ezolt.]
|
---|
| 1209 | Handle XObjects with recursive references in their Resources
|
---|
| 1210 | dictionaries (in PSOutputDev).
|
---|
| 1211 | Change PSOutputDev to deal with invalid PDF files that use
|
---|
| 1212 | non-embedded TrueType fonts with no encoding.
|
---|
| 1213 | Check for undersized Widths arrays in fonts.
|
---|
| 1214 | Add bounds checking code to Array class.
|
---|
| 1215 | Updated VMS build scripts. [Thanks to Martin Zinser.]
|
---|
| 1216 | Tweak the TrueType font handling code (again):
|
---|
| 1217 | - char codes in symbolic fonts may or may not be offset by 0xf000
|
---|
| 1218 | - discard empty tables because they sometimes confuse FreeType
|
---|
| 1219 | Fixed bounds checking in the Flate decoder.
|
---|
| 1220 | Removed a bogus error message for exponential functions without
|
---|
| 1221 | explicit C0/C1 values. [Thanks to Hartmut Henkel.]
|
---|
| 1222 | Handle the other Unicode cmap type (platform=0) in TrueType fonts.
|
---|
| 1223 | Added support for the SGI Motif horizontal paned window widget.
|
---|
| 1224 | [Thanks to Felix Ritter.]
|
---|
| 1225 | Ignore extra elements in link destination arrays.
|
---|
| 1226 | Accept external Type 1 font files with a suffix of ".ps" or no suffix
|
---|
| 1227 | at all.
|
---|
| 1228 | Add a bounds check in the DCT decoder.
|
---|
| 1229 | Added instructions for building xpdf.exe under cygwin/XFree86.
|
---|
| 1230 | Tweaked the word separation parameter for raw-mode text extraction.
|
---|
| 1231 |
|
---|
| 1232 | 2.03 (2003-oct-10)
|
---|
| 1233 | ------------------
|
---|
| 1234 | Rewrote the text extractor to:
|
---|
| 1235 | - do a better job with rotated text;
|
---|
| 1236 | - handle right-to-left scripts;
|
---|
| 1237 | - be faster.
|
---|
| 1238 | Changed the zoom setting to use a percentage (relative to 72 dpi)
|
---|
| 1239 | instead of a zoom "factor".
|
---|
| 1240 | If the PDF file has an outline, open the outline pane initially.
|
---|
| 1241 | Added -f and -l options to pdfinfo; print multiple page sizes.
|
---|
| 1242 | The HAVE_XTAPPSETEXITFLAG test in XPDFApp.cc was backwards.
|
---|
| 1243 | The BitsPerComponent entry is optional in image mask objects.
|
---|
| 1244 | Render any annotation with an appearance stream, instead of just
|
---|
| 1245 | Widget and Stamp annotations.
|
---|
| 1246 | Fix a bug in the TrueType font checker: the test for an unsorted
|
---|
| 1247 | 'loca' table was wrong.
|
---|
| 1248 | Modify the TrueType cmap selection algorithm yet again to try to match
|
---|
| 1249 | Adobe's behavior.
|
---|
| 1250 | Changed sqrt(2) to sqrt(2.0) in pdfinfo.cc to make various compilers
|
---|
| 1251 | happy.
|
---|
| 1252 | Fixed a deadlock problem (when MULTITHREADING is set); cleaned up some
|
---|
| 1253 | other problems with the locking code.
|
---|
| 1254 | Fixed a bug in the interpolation code for type 0 (sampled) functions.
|
---|
| 1255 | Implemented type 1 (function-based) shaded fills.
|
---|
| 1256 | Fixed some stupid bugs in the JBIG2 decoder (introduced with the
|
---|
| 1257 | previous optimization work).
|
---|
| 1258 | Fixed a typo in the code that parses vertical font metrics for CID
|
---|
| 1259 | fonts that was causing a seg fault.
|
---|
| 1260 | Fixed a couple of bugs that were causing seg faults with badly damaged
|
---|
| 1261 | PDF files.
|
---|
| 1262 | Limit the number of nested Forms to avoid infinite recursion (in buggy
|
---|
| 1263 | PDF files).
|
---|
| 1264 | Add a special case for rectangular clip regions - make sure these
|
---|
| 1265 | don't drop pixels on the right and bottom edges.
|
---|
| 1266 | Tell FreeType not to use glyph bitmaps when in anti-aliased mode.
|
---|
| 1267 | Read all of the border style info for links.
|
---|
| 1268 | All of the shaded fill types now do at least one bisection to avoid
|
---|
| 1269 | problems when the colors at the endpoints of the domain are the
|
---|
| 1270 | same.
|
---|
| 1271 | If the Length2 parameter for an embedded Type 1 font was incorrect
|
---|
| 1272 | (too small), pdftops was losing font data.
|
---|
| 1273 | Deal with (broken) DCT streams that use the same component ID number
|
---|
| 1274 | for different components.
|
---|
| 1275 | The MediaBox page attribute was not being inherited correctly.
|
---|
| 1276 | Fixed a bug in the Type 1C font converter related to local
|
---|
| 1277 | subroutines.
|
---|
| 1278 | The Type 1C -> Type 1 font converter was allocating the font dictionary
|
---|
| 1279 | one slot too small.
|
---|
| 1280 | Added a missing private dictionary entry to Type 1 fonts generated by
|
---|
| 1281 | the Type 1C converter. [Thanks to Michael Shell.]
|
---|
| 1282 | Fixed bugs in the tiling pattern fill code.
|
---|
| 1283 | Try the TrueType 0xf000 char code offset hack for the MacRoman
|
---|
| 1284 | encoding too (in addition to MS Symbol).
|
---|
| 1285 | Update the font metrics info for the Base 14 fonts to include the Euro
|
---|
| 1286 | character.
|
---|
| 1287 | SECURITY HOLE: Escape various characters in URLs before running a web
|
---|
| 1288 | browser (or movie viewer). [Fixed in 2.02p11]
|
---|
| 1289 | SECURITY HOLE: In the dialog used to verify "launch" links, provide a
|
---|
| 1290 | scrolling view if the command to be run is excessively long. [Fixed
|
---|
| 1291 | in 2.02p11]
|
---|
| 1292 | Added an option to disable insertion of page breaks (form feed
|
---|
| 1293 | characters) in extracted text (pdftotext -nopgbrk; xpdfrc
|
---|
| 1294 | "textPageBreaks" option).
|
---|
| 1295 | Check for 8-bit fonts that specify an out-of-range FirstChar or
|
---|
| 1296 | LastChar.
|
---|
| 1297 | Correctly handle an obsolete Type 2 charstring op (in the Type
|
---|
| 1298 | 1C-to-Type 1 font converter). [Thanks to Helge Blischke.]
|
---|
| 1299 | Use the font encoding info to fill in holes in the ToUnicode map.
|
---|
| 1300 | Added character names for Bulgarian (in the Cyrillic support pacakage)
|
---|
| 1301 | and Greek.
|
---|
| 1302 | Handle clipping to text in xpdf and pdftops.
|
---|
| 1303 | Fix color space detection in DCT decoder. [Thanks to Dwight Kelly.]
|
---|
| 1304 | Added the "unicodeToUnicode" xpdfrc option, intended (initially) for
|
---|
| 1305 | Arabic support.
|
---|
| 1306 | Handle the case in PSOutputDev where two font objects refer to the
|
---|
| 1307 | same embedded TrueType font, but with different encodings. [Thanks
|
---|
| 1308 | to Frank Siegert.]
|
---|
| 1309 | Kill any pre-existing path before drawing a form (or annotation).
|
---|
| 1310 | Save state before rendering page content; restore state afterward.
|
---|
| 1311 | Fix Stream::reset/close to work correctly with encoder streams; fix
|
---|
| 1312 | PSOutputDev to use Stream::close consistently.
|
---|
| 1313 | Fix a seg fault when hitting the 'back' button after closing a file.
|
---|
| 1314 | GfxState::getStrokeGray was returning the fill gray value (this only
|
---|
| 1315 | affected Level 1 PS output).
|
---|
| 1316 | Change PSOutputDev to reuse dictionaries in Level 1 mode (since Level
|
---|
| 1317 | 1 PS interpreters don't do garbage collection). [Thanks to Frank
|
---|
| 1318 | Siegert.]
|
---|
| 1319 | PSOutputDev was generating incorrect translations for landscape-mode
|
---|
| 1320 | pages.
|
---|
| 1321 | Implemented shading pattern color spaces.
|
---|
| 1322 | PSOutputDev wasn't correctly handling Type 3 fonts which used image
|
---|
| 1323 | resources (as opposed to inline images). [Thanks to Frank Siegert.]
|
---|
| 1324 | The fix from 1.00 which clipped out-of-bounds points was a bit too
|
---|
| 1325 | aggressive.
|
---|
| 1326 | Do proper Floyd-Steinberg dithering in XOutputDev.
|
---|
| 1327 | Don't automatically check for a null owner password (to match Adobe's
|
---|
| 1328 | behavior).
|
---|
| 1329 | Allow the FlateDecode filter in Level 3 PostScript output.
|
---|
| 1330 | Fixed small bugs in the Type 1C -> Type 1 converter and Type 1C ->
|
---|
| 1331 | Type 0 converter. [Thanks to Tom Kacvinsky.]
|
---|
| 1332 | Work around another weird Motif problem with the right button menu
|
---|
| 1333 | (which was sometimes causing the menu to not be displayed).
|
---|
| 1334 | Make the code that handles fonts defined directly in the resource dict
|
---|
| 1335 | more robust.
|
---|
| 1336 | Add a brief description of the outline pane to the xpdf man page.
|
---|
| 1337 | Ignore extra operands to content stream operators.
|
---|
| 1338 | Fixed a bug in the CCITTFax decoder.
|
---|
| 1339 | Allow the Count entry in a Pages dictionary to be a real number
|
---|
| 1340 | (because some PDF generators actually do this).
|
---|
| 1341 | Shading pattern fills weren't being clipped correctly.
|
---|
| 1342 | Incorrect shallow copies in GfxRadialShading and StitchingFunction.
|
---|
| 1343 | The StitchingFunction destructor wasn't checking for funcs being
|
---|
| 1344 | NULL.
|
---|
| 1345 | Change the TrueType code-to-GID mapping code so it looks at the
|
---|
| 1346 | TrueType 'post' table.
|
---|
| 1347 | Set the print command in the print dialog once at startup, don't
|
---|
| 1348 | change it each time a file is (re)loaded.
|
---|
| 1349 | Generate the %%BoundingBox comment in regular PostScript files (not
|
---|
| 1350 | just EPS files).
|
---|
| 1351 | Fixed a bug in the Unicode CMap parser.
|
---|
| 1352 |
|
---|
| 1353 | 3.00 (2004-jan-22)
|
---|
| 1354 | ------------------
|
---|
| 1355 | New PDF rasterizer ("Splash").
|
---|
| 1356 | Added support for PDF 1.5:
|
---|
| 1357 | - JPX (JPEG 2000) decoder
|
---|
| 1358 | - XRef streams
|
---|
| 1359 | - object streams
|
---|
| 1360 | - DeviceN color spaces with up to 32 components
|
---|
| 1361 | - Added new CMaps to the CJK language support packages
|
---|
| 1362 | Replaced pdftopbm with pdftoppm (which can generate PBM, PGM, and PPM
|
---|
| 1363 | files).
|
---|
| 1364 | Reorganized the font file parser code into a new library ("Fofi").
|
---|
| 1365 | Removed support for FreeType 1.x.
|
---|
| 1366 | Removed support for X server fonts - Xpdf (and pdftoppm) will now
|
---|
| 1367 | search for the URW fonts (from ghostscript).
|
---|
| 1368 | Changed the "-t1lib" and "-freetype" switches; replaced the
|
---|
| 1369 | "t1libControl" and "freetypeControl" config file options with
|
---|
| 1370 | "enableT1lib", "enableFreeType", and "antialias".
|
---|
| 1371 | Added the "-box" option to pdfinfo.
|
---|
| 1372 | Added imageable area support to PSOutputDev (for CUPS); added the
|
---|
| 1373 | "psImageableArea" config file option.
|
---|
| 1374 | Added the "-nocrop", "-expand", "-noshrink", and "-nocenter" switches
|
---|
| 1375 | to pdftops; added the "psCrop", "psExpandSmaller", "psShrinkLarger",
|
---|
| 1376 | and "psCenter" config file options.
|
---|
| 1377 | Dictionary size was in PostScript code generated for Type 3 fonts.
|
---|
| 1378 | The PS code generated for images in Type 3 characters was broken.
|
---|
| 1379 | Tweaked the text extractor.
|
---|
| 1380 | Accept xref entries that are one byte too short (matching Adobe's
|
---|
| 1381 | behavior).
|
---|
| 1382 | Change things so "xpdf -h" and "xpdf -v" work if DISPLAY isn't set.
|
---|
| 1383 | Fix a problem in the damaged file repair code that handles the trailer
|
---|
| 1384 | dictionary.
|
---|
| 1385 | Use the "Last" entries in "Outlines" objects - this avoids a problem
|
---|
| 1386 | with PDF files generated by buggy software that, e.g., sets the last
|
---|
| 1387 | item's Next pointer to point to itself.
|
---|
| 1388 | PSOutputDev was not handling DeviceN color spaces correctly in Level 2
|
---|
| 1389 | images.
|
---|
| 1390 | Fixed a stupid little bug that broke PS output for JBIG2 images.
|
---|
| 1391 | Work around a Lesstif bug: set up an extra callback so hitting <Enter>
|
---|
| 1392 | in the find dialog performs a search. [Thanks to Elliott Hughes.]
|
---|
| 1393 | Pdftops was crashing on zero page PDF files.
|
---|
| 1394 | Add an AC_PREREQ call to configure.in.
|
---|
| 1395 | Change the 'find' dialog so the text entry box resizes with the
|
---|
| 1396 | dialog.
|
---|
| 1397 | Skip extraneous zero bits at the start of a CCITTFax stream.
|
---|
| 1398 | The PostScript text clipping operator was missing a 'newpath'.
|
---|
| 1399 | [Thanks to Frank Siegert.]
|
---|
| 1400 | Fix a bug in tiling patterns with bboxes that don't start at (0,0).
|
---|
| 1401 | Fix a bug in Type 3 font handling with rotated text.
|
---|
| 1402 | The tiled pattern fill code was destroying the current path, which
|
---|
| 1403 | broke the fill+stroke operators when the fill color space was a
|
---|
| 1404 | tiled pattern.
|
---|
| 1405 | ICCBased color spaces don't always set their Ranges values correctly,
|
---|
| 1406 | so just use the values from the alternate color space.
|
---|
| 1407 | Modified GHash to accept int or void* - this avoids some conversion
|
---|
| 1408 | warnings.
|
---|
| 1409 | Check for missing Type 3 CharProcs - avoid a segfault.
|
---|
| 1410 | Pdffonts now marks all Type 3 fonts as embedded.
|
---|
| 1411 | Outline entries with no Title string weren't being handled correctly,
|
---|
| 1412 | resulting in segfaults.
|
---|
| 1413 | PSOutputDev now forces the text horizontal scale factor to be non-zero
|
---|
| 1414 | to avoid singular font matrices in the PS code.
|
---|
| 1415 | Tweaked the error recovery in the CCITTFax decoder.
|
---|
| 1416 | The LZW/Flate predictor should treat any Predictor value (in the
|
---|
| 1417 | stream dictionary) >= 10 identically.
|
---|
| 1418 | PSOutputDev and pdffonts check for NULL font objects (which can
|
---|
| 1419 | happen, e.g., because of missing CMap files).
|
---|
| 1420 | Swap the left and right mouse wheel button numbers.
|
---|
| 1421 | EPS output ("pdftops -eps") now uses the CropBox instead of the
|
---|
| 1422 | MediaBox as the EPS bounding box.
|
---|
| 1423 |
|
---|
| 1424 | 3.01 (2005-aug-17)
|
---|
| 1425 | ------------------
|
---|
| 1426 | Added the continuous view mode, including the '-cont' switch and the
|
---|
| 1427 | 'continuousView' config file option.
|
---|
| 1428 | At high zoom levels, don't rasterize the entire page - this avoids
|
---|
| 1429 | problems running out of memory.
|
---|
| 1430 | Added "search backward" and "match case" options to the find dialog.
|
---|
| 1431 | Support explicitly masked images and soft masked images.
|
---|
| 1432 | Add support to DCTStream for 16-bit quant tables.
|
---|
| 1433 | Don't segfault if the user clicks on an outline entry with a broken
|
---|
| 1434 | destination.
|
---|
| 1435 | Changed the makefiles and configure script to skip building pdftoppm
|
---|
| 1436 | (in addition to xpdf) if X, Motif, or FreeType is not found; changed
|
---|
| 1437 | the error message in the configure script to match.
|
---|
| 1438 | Move an inline function in JArithmeticDecoder.cc to avoid compiler
|
---|
| 1439 | errors.
|
---|
| 1440 | Fixed a bug in the rasterizer that was sometimes causing infinite
|
---|
| 1441 | loops with round line caps on vertical lines.
|
---|
| 1442 | Various rasterizer optimizations.
|
---|
| 1443 | Look for intermediate resize events - try to avoid lagging when the
|
---|
| 1444 | user is doing an opaque resize.
|
---|
| 1445 | The FormType key in Form XObjects is optional.
|
---|
| 1446 | Handle external 16-bit TrueType fonts correctly, using the Unicode
|
---|
| 1447 | cmap.
|
---|
| 1448 | Add class declarations to TextOutputDev.h to work with stricter C++
|
---|
| 1449 | compilers.
|
---|
| 1450 | Support FreeType's weird include file stuff (ft2build.h, etc.).
|
---|
| 1451 | Fixed a bug handling empty paths.
|
---|
| 1452 | Fixed a text positioning problem in PostScript output.
|
---|
| 1453 | Handle TrueType collections in FoFiTrueType.cc.
|
---|
| 1454 | FoFiTrueType constructor was reporting a failure if the post table was
|
---|
| 1455 | bad - this should be non-fatal.
|
---|
| 1456 | Type 1 font parser was missing a NULL test.
|
---|
| 1457 | Mask chars passed to isdigit in goo/parseargs.c to avoid problems with
|
---|
| 1458 | signed chars.
|
---|
| 1459 | Added more error checking to the CCITTFax decoder.
|
---|
| 1460 | Fixed a bug (computing the MCU size) in the DCT decoder.
|
---|
| 1461 | Change a test in the Splash stroke code to avoid x86 floating point
|
---|
| 1462 | weirdness.
|
---|
| 1463 | Reorganized the decryption code to allow security handler plugins;
|
---|
| 1464 | removed the NO_DECRYPTION #ifdefs.
|
---|
| 1465 | Added a plugin interface, initially just for security handlers.
|
---|
| 1466 | Support color key masked images and explicitly masked images in PS
|
---|
| 1467 | output (Level 2 only).
|
---|
| 1468 | When checking for aliases of the Base 14 fonts, ignore spaces in the
|
---|
| 1469 | specified font name.
|
---|
| 1470 | Handle encrypted PDF files that are missing the file ID string.
|
---|
| 1471 | Handle tiling patterns more efficiently in the PostScript output.
|
---|
| 1472 | Rewrote the code that handles color spaces in PostScript output.
|
---|
| 1473 | Fixed a bug in the Type 1C font parser - zero-length indexes (and
|
---|
| 1474 | zero-length names) weren't handled correctly.
|
---|
| 1475 | Handle shaded fills more efficiently in the PostScript output.
|
---|
| 1476 | Implement the remaining shading types (4-7).
|
---|
| 1477 | Rearranged the Splash color modes.
|
---|
| 1478 | Add the EarlyChange parameter to LZWStream when generating PostScript.
|
---|
| 1479 | Check for zero values in line dash arrays in PSOutputDev.
|
---|
| 1480 | Fixed an uninitialized variable in JArithmeticDecoder which was
|
---|
| 1481 | causing crashes.
|
---|
| 1482 | Treat unknown CMap names as identity mappings (to match Adobe's
|
---|
| 1483 | behavior).
|
---|
| 1484 | Fixed bugs in the XRef parser related to XRef streams in updated
|
---|
| 1485 | files.
|
---|
| 1486 | Added a missing call to FT_Done_Glyph which was causing a memory leak.
|
---|
| 1487 | [Thanks to Dave Formanek.]
|
---|
| 1488 | Fixed a bug in text copying that was causing the last word to be
|
---|
| 1489 | dropped on some pages.
|
---|
| 1490 | Tweaked the image width/height computation in Splash::drawImage and
|
---|
| 1491 | Splash::fillImageMask to make striped images work better.
|
---|
| 1492 | Ignore minus signs in the middle of numbers (to match Adobe's
|
---|
| 1493 | behavior).
|
---|
| 1494 | Missing '%s' in format strings for dates in pdftotext '-htmlmeta'
|
---|
| 1495 | mode.
|
---|
| 1496 | Change the TrueType code-to-GID mapping code so it looks at the
|
---|
| 1497 | standard name-to-Unicode mapping before the ToUnicode mapping
|
---|
| 1498 | defined in the font object.
|
---|
| 1499 | Added a matteColor setting (command line option and X resource).
|
---|
| 1500 | Tweaked the CMYK->RGB transform.
|
---|
| 1501 | Fix some problems in tracking the character position (to match up with
|
---|
| 1502 | Adobe's highlight file format).
|
---|
| 1503 | Handle moveto/closepath/stroke correctly.
|
---|
| 1504 | Check for singular text matrices and font size of zero in PSOutputDev.
|
---|
| 1505 | Clip PS output to the size of the page (avoiding any gibberish that
|
---|
| 1506 | lies outside the MediaBox, in the case where the MediaBox is smaller
|
---|
| 1507 | than the paper).
|
---|
| 1508 | If the line dash element in an annotation's Border array is of an
|
---|
| 1509 | invalid type (i.e., not an array), don't draw the link at all (this
|
---|
| 1510 | matches Adobe's behavior).
|
---|
| 1511 | Don't remap small caps and oldstyle glyphs in the name-to-Unicode
|
---|
| 1512 | table - it messes up TrueType font encodings.
|
---|
| 1513 | Pdftoppm wasn't setting the paper color correctly in mono and gray
|
---|
| 1514 | modes (this only showed up on big-endian machines).
|
---|
| 1515 | Missing NULL check was causing crashes when attempting to read non-PDF
|
---|
| 1516 | files that happened to contain the string '%PDF'.
|
---|
| 1517 | Fixed a problem in the text extractor that was breaking up words.
|
---|
| 1518 | Handle vertical text (CJK fonts) in PS output with TrueType fonts that
|
---|
| 1519 | are missing the vertical metrics tables.
|
---|
| 1520 | Handle the case where a font object and the corresponding embedded
|
---|
| 1521 | font are different types.
|
---|
| 1522 | Handle basic crypt filter functionality.
|
---|
| 1523 | Added more value checking in the XRef parser, to avoid potential
|
---|
| 1524 | security problems.
|
---|
| 1525 | Updated the CJK language support packages: replaced the
|
---|
| 1526 | displayCIDFontX references with displayCIDFontTT; added pointers to
|
---|
| 1527 | free TrueType fonts.
|
---|
| 1528 | Added a missing error message when SplashOutputDev can't parse an
|
---|
| 1529 | embedded TrueType font file.
|
---|
| 1530 | PDFCore and TextOutputDev now correctly handle searching for Unicode
|
---|
| 1531 | strings, including real Unicode case-folding.
|
---|
| 1532 | Throw away tiling pattern fills that are completely outside the clip
|
---|
| 1533 | region.
|
---|
| 1534 | The JPEG 2000 inverse reversible multiple component transform code was
|
---|
| 1535 | wrong.
|
---|
| 1536 | Fixed some bugs in shading pattern fills: clipping was wrong, and
|
---|
| 1537 | background color was not implemented.
|
---|
| 1538 | Added tool tips for the toolbar buttons.
|
---|
| 1539 | Decrease the max depth of recursive patch mesh filling if the pattern
|
---|
| 1540 | has a large number of patches.
|
---|
| 1541 | Highlight the find text whenever the find dialog is mapped.
|
---|
| 1542 | Handle page boundary boxes with reversed coordinates.
|
---|
| 1543 | Fixed a bug in the text extractor code that handles duplicated text.
|
---|
| 1544 | Optimization work on SampledFunction::transform().
|
---|
| 1545 | Use the CropBox instead of the MediaBox as the display region.
|
---|
| 1546 | Dither for PseudoColor (8-bit) displays.
|
---|
| 1547 | Fix a bug in DCTStream that was causing an infinite loop with
|
---|
| 1548 | corrupted DCT image data.
|
---|
| 1549 | Fix a bug in the ToUnicode CMap parser.
|
---|
| 1550 | Fix a bug in the text extractor - negative font sizes weren't being
|
---|
| 1551 | handled correctly.
|
---|
| 1552 | Fix a bug in the text extractor - in certain cases, out-of-bounds text
|
---|
| 1553 | could cause crashes (generally only in damaged PDF files).
|
---|
| 1554 | Fix a read-past-end-of-array bug in the JBIG2 decoder.
|
---|
| 1555 | Fix a case where pdftops was generating lines longer than 255 chars.
|
---|
| 1556 | Optimize redraws - don't regenerate the XImage every time redrawRect
|
---|
| 1557 | is called.
|
---|
| 1558 | The ASCII85 decoder wasn't skipping whitespace properly.
|
---|
| 1559 | Optimize text extraction: skip (non-inline) image setup entirely.
|
---|
| 1560 | Added initial transparency support (stroke/fill alpha and blend mode).
|
---|
| 1561 | Added support for the overprint setting in PostScript output.
|
---|
| 1562 | Fixed various buffer overflow bugs.
|
---|
| 1563 | Handle negative font sizes and horizontal scaling correctly - this
|
---|
| 1564 | affected PSOutputDev for all text operators, as well as the TJ
|
---|
| 1565 | operator for all OutputDevs.
|
---|
| 1566 | Fixed a buffer overflow in the CCITTFax decoder.
|
---|
| 1567 | Fixed an out-of-order entry in the list of font name aliases.
|
---|
| 1568 | Fixed a backward loop in the PostScriptFunction code.
|
---|
| 1569 | Treat a zero-length base URI the same way as a nonexistent base URI.
|
---|
| 1570 | Add a divide-by-zero check in TextOutputDev (the problem was happening
|
---|
| 1571 | in cases of mixed horizontal and vertical text).
|
---|
| 1572 | PSOutputDev wasn't rounding the page bounding box coordinates
|
---|
| 1573 | correctly.
|
---|
| 1574 | Support the SOF1 marker in DCT (JPEG) image streams.
|
---|
| 1575 | Minor changes to GlobalParams.h and JPXStream.h because some compilers
|
---|
| 1576 | don't like anonymous structs inside anonymous unions.
|
---|
| 1577 | Xpdf now complains about a negative page number.
|
---|
| 1578 | Changed GString::cmp and GString::cmpN to correctly handle '\0' chars
|
---|
| 1579 | in the middle of strings.
|
---|
| 1580 | Fixed the radial shading code; corrected the handling of the 'extend'
|
---|
| 1581 | parameters.
|
---|
| 1582 | Added the gmallocn and greallocn functions.
|
---|
| 1583 | Fixed a bug in the TIFF image component predictor which shows up with
|
---|
| 1584 | components that are not 1 or 8 bits wide.
|
---|
| 1585 | Optimized FlateStream::loadFixedCodes().
|
---|
| 1586 | For non-embedded Base-14 fonts, don't use the ascent/descent/bbox
|
---|
| 1587 | values from the FontDescriptor - various PDF generators get them
|
---|
| 1588 | wrong.
|
---|
| 1589 | Fixed a bug in the text extractor - words on the same line (especially
|
---|
| 1590 | in tables) were being split vertically onto multiple lines.
|
---|
| 1591 | Automatically select the correct radio button ("print with command"
|
---|
| 1592 | vs. "print to file") in the print dialog.
|
---|
| 1593 | Don't create the "open" and "save as" dialogs until needed - this
|
---|
| 1594 | avoids stat-ing every file in the directory at startup.
|
---|
| 1595 | Changed the Big5 and Big5ascii encodings (in the traditional Chinese
|
---|
| 1596 | language support package) to include characters from the Unicode
|
---|
| 1597 | database (which aren't mentioned in the Adobe character collection
|
---|
| 1598 | documentation).
|
---|
| 1599 | Added the '-pagecrop' switch to pdftops.
|
---|
| 1600 | Tweaked the RGB->gray and CMYK->gray conversion functions to match the
|
---|
| 1601 | PDF spec.
|
---|
| 1602 | The JPEG 2000 decoder wasn't correctly handling codeblocks split
|
---|
| 1603 | across multiple packets/layers.
|
---|
| 1604 | Fixed a typecast that caused compile errors on 64-bit systems.
|
---|
| 1605 | The CMap parser wasn't handling the 'cidchar' construct.
|
---|
| 1606 | Handle the case in PSOutputDev where two font objects refer to the
|
---|
| 1607 | same embedded 16-bit TrueType font, but with different CIDToGIDMaps.
|
---|
| 1608 | Changed the configure script to report more accurate warnings when
|
---|
| 1609 | it can't find X / Motif / FreeType.
|
---|
| 1610 | Encryption with revision=2 always uses a 40-bit key, regardless of the
|
---|
| 1611 | specified Length value.
|
---|
| 1612 | Yet another minor change to the TrueType font encoding deciphering
|
---|
| 1613 | algorithm.
|
---|
| 1614 | Don't completely invalidate the Catalog if one (or more) of the page
|
---|
| 1615 | objects are bogus -- just skip over those pages.
|
---|
| 1616 | Removed the workaround in pdftops for too-small Length2 values in Type
|
---|
| 1617 | 1 fonts -- it was causing problems on various PostScript printers.
|
---|
| 1618 | Started adding error checking to the JBIG2 decoder (this is nowhere
|
---|
| 1619 | near complete yet).
|
---|
| 1620 | Extended the "unicodeToUnicode" config option to also apply to CID
|
---|
| 1621 | fonts.
|
---|
| 1622 | Added the narrow Latin characters to the Adobe-Korea1.cidToUnicode
|
---|
| 1623 | file in the Korean language support package.
|
---|
| 1624 | Fixed the code that handles page rotation in PSOutputDev.
|
---|
| 1625 | When converting a Type 1C glyph to a Type 1 glyph, insert closepath
|
---|
| 1626 | operators as appropriate.
|
---|
| 1627 | Check for a sane 'loca' table in TrueType fonts (FoFiTrueType::parse).
|
---|
| 1628 | Fix PSOutputDev to correctly handle the case of an empty name in a
|
---|
| 1629 | font encoding.
|
---|
| 1630 |
|
---|
| 1631 | 3.02 (2007-feb-27)
|
---|
| 1632 | ------------------
|
---|
| 1633 | Added anti-aliasing for vector graphics; added the vectorAntialias
|
---|
| 1634 | xpdfrc option; added the "-aaVector" switch to xpdf and pdftoppm.
|
---|
| 1635 | Implemented stroke adjustment (always enabled by default, ignoring the
|
---|
| 1636 | SA parameter, to match Adobe's behavior), and added the strokeAdjust
|
---|
| 1637 | xpdfrc command.
|
---|
| 1638 | Support PDF 1.6 and PDF 1.7.
|
---|
| 1639 | Added support for AES decryption.
|
---|
| 1640 | Added support for OpenType fonts (only tested with 8-bit CFF data so
|
---|
| 1641 | far).
|
---|
| 1642 | Added user-configurable key/mouse bindings - the bind/unbind xpdfrc
|
---|
| 1643 | commands.
|
---|
| 1644 | Cleaned up the full-screen mode code and added the ability to toggle
|
---|
| 1645 | it on the fly (the default key binding is alt-f).
|
---|
| 1646 | Pdfimages with the -j option now writes JPEG files for 1-component
|
---|
| 1647 | (grayscale) DCT images, in addition to 3-component (RGB) images.
|
---|
| 1648 | Fixed bugs in handling sampled (type 0) functions with 32-bit
|
---|
| 1649 | samples.
|
---|
| 1650 | Fixed some things to support DeviceN color spaces with up to 32
|
---|
| 1651 | colorants.
|
---|
| 1652 | Pdftops now constructs the %%Creator and %%Title DSC comments from the
|
---|
| 1653 | relevant information in the PDF Info dictionary.
|
---|
| 1654 | Tweak the TrueType font encoding deciphering algorithm.
|
---|
| 1655 | Added the "mapUnkownCharNames" xpdfrc option.
|
---|
| 1656 | Fix a bug (that only showed up with certain window managers) in the
|
---|
| 1657 | intermediate resize event optimization. [Thanks to Michael Rogers.]
|
---|
| 1658 | Check for a broken/missing embedded font (this was causing xpdf to
|
---|
| 1659 | crash).
|
---|
| 1660 | Added support for transfer functions in PostScript output.
|
---|
| 1661 | Be a bit more tolerant of Link destinations that contain null values
|
---|
| 1662 | for positioning parameters.
|
---|
| 1663 | Use ordered dot dithering instead of clustered dot dithering at
|
---|
| 1664 | resolutions below 300 dpi (for monochrome output).
|
---|
| 1665 | Fixed security holes (bounds checking issues) in several places.
|
---|
| 1666 | Don't bother creating a SplashFont (allocating memory) for fonts that
|
---|
| 1667 | are only used for hidden text - this avoids problems with fonts of
|
---|
| 1668 | unreasonably large sizes.
|
---|
| 1669 | Clipping in TextOutputDev was off for characters on the left edge of
|
---|
| 1670 | the page.
|
---|
| 1671 | The scn and SCN operators weren't correctly handling colors with more
|
---|
| 1672 | than four components.
|
---|
| 1673 | FoFiType1::writeEncoded wasn't always correctly finding the end of the
|
---|
| 1674 | encoding.
|
---|
| 1675 | Use the ColorTransform parameter in the DCTDecode stream dictionary.
|
---|
| 1676 | Type 3 fonts are allowed to have a bbox of [0 0 0 0], which means
|
---|
| 1677 | "unspecified" -- don't issue error messages in that case.
|
---|
| 1678 | Perform the transform (to device space) in Splash instead of in
|
---|
| 1679 | SplashOutputDev -- this is needed to correctly handle round joins
|
---|
| 1680 | and caps on stroked paths.
|
---|
| 1681 | PSOutputDev now rasterizes any pages that use transparency.
|
---|
| 1682 | Limit the crop, bleed, trim, and art boxes to the edges of the media
|
---|
| 1683 | box (per the PDF spec).
|
---|
| 1684 | Change GString to increase the allocation increment by powers of two.
|
---|
| 1685 | Handle whitespace in hex strings in CMap files/streams.
|
---|
| 1686 | Use strings instead of names for separation colorant names in
|
---|
| 1687 | PSOutputDev.
|
---|
| 1688 | For explicitly masked images where the mask is higher resolution than
|
---|
| 1689 | the image, use the soft mask code.
|
---|
| 1690 | Avoid problems with very large x-steps in the PostScript output for
|
---|
| 1691 | tiling pattern fills.
|
---|
| 1692 | Avoid a divide-by-zero in stitching functions which have a subfunction
|
---|
| 1693 | with empty bounds.
|
---|
| 1694 | Honor the "Hidden", "NoView", and "Print" flags on annotations.
|
---|
| 1695 | Rewrote the pixel rendering code in Splash to use a single set of
|
---|
| 1696 | pixel pipeline functions.
|
---|
| 1697 | Added support for transparency groups and soft masks.
|
---|
| 1698 | Fixed the transparency blend functions to match the addendum published
|
---|
| 1699 | by Adobe.
|
---|
| 1700 | Changed Splash/SplashBitmap to store alpha in a separate plane.
|
---|
| 1701 | Setting the color space now selects the correct default color for that
|
---|
| 1702 | color space.
|
---|
| 1703 | Remove the mutex lock from GlobalParams::getErrQuiet() to avoid a
|
---|
| 1704 | deadlock when parseCIDToUnicode() or parseUnicodeToUnicode() calls
|
---|
| 1705 | it from inside a locked section.
|
---|
| 1706 | Added error checking (on the argument count) in the sc/SC/scn/SCN
|
---|
| 1707 | operators.
|
---|
| 1708 | Skip over notdef glyphs in TrueType fonts (which sometimes get drawn
|
---|
| 1709 | as little boxes), to match Adobe's behavior.
|
---|
| 1710 | Painting operations in a Separation color space with the "None"
|
---|
| 1711 | colorant or a DeviceN color space with all colorants set to "None"
|
---|
| 1712 | never mark the page.
|
---|
| 1713 | Fixed an obscure bug in the JPX decoder - it wasn't reading the extra
|
---|
| 1714 | stuffing byte in the case where the last byte of a packet header was
|
---|
| 1715 | 0xff.
|
---|
| 1716 | Change the TrueType font parser (FoFiTrueType) to change the glyph
|
---|
| 1717 | count rather than report an error if the 'loca' table is too small.
|
---|
| 1718 | Fixed a couple of bugs in the JBIG2 decoder.
|
---|
| 1719 | Added stochastic clustered dot dithering.
|
---|
| 1720 | Added the screenType, screenSize, screenDotRadius, screenGamma,
|
---|
| 1721 | screenBlackThreshold, and screenWhiteThreshold xpdfrc settings.
|
---|
| 1722 | PSOutputDev now correctly handles invalid Type 3 charprocs which don't
|
---|
| 1723 | start with a d0 or d1 operator
|
---|
| 1724 | FreeType 2.2.x support - get rid of the FT_INTERNAL_OBJECTS_H include,
|
---|
| 1725 | and add some 'const' declarations.
|
---|
| 1726 | Handle PDFDocEncoding in Info dictionary strings.
|
---|
| 1727 | Tweak the xref repair code - ignore whitespace at the start of lines
|
---|
| 1728 | when looking for objects.
|
---|
| 1729 | Added the "-exec" switch to xpdf.
|
---|
| 1730 | Removed the xpdf.viKeys X resource.
|
---|
| 1731 | Changed the color key / explicit masked image code in PSOutputDev to
|
---|
| 1732 | generate better PS code, including a Level 3 option.
|
---|
| 1733 | Tweaked the DEBUG_MEM code for performance.
|
---|
| 1734 | Move the JBIG2 global stream reading code into reset() instead of the
|
---|
| 1735 | constructor - this way, pdftotext doesn't end up reading the global
|
---|
| 1736 | stream.
|
---|
| 1737 | Added the "-preload" option to pdftops and the psPreload xpdfrc
|
---|
| 1738 | command.
|
---|
| 1739 | Added the "zoom to selection" command (on the popup menu).
|
---|
| 1740 | Fix a bug (in xpdf/pdftoppm/pdftops) with tiling patterns whose bbox
|
---|
| 1741 | size is different from their xStep/yStep.
|
---|
| 1742 | Implemented stroke with pattern color spaces.
|
---|
| 1743 | Following a link to a page whose CropBox was different from the
|
---|
| 1744 | MediaBox was resulting in an incorrect scroll position.
|
---|
| 1745 | Parse truncated date strings from the Info dictionary correctly.
|
---|
| 1746 | Change FoFiType1 to handle Type 1 fonts with two /Encoding keys.
|
---|
| 1747 | Extend the PSOutputDev shaded fill code to handle DeviceCMYK shaded
|
---|
| 1748 | fills in level2sep and level3sep modes.
|
---|
| 1749 | Detect infinite loops in the Page tree.
|
---|
| 1750 | Optimized the ASCII85Encoder code.
|
---|
| 1751 | Tweaked the text extractor to do a better job of lining up rows of
|
---|
| 1752 | text.
|
---|
| 1753 | Leave images compressed (or re-compress them with RLE) in PostScript
|
---|
| 1754 | output when setting up images for forms and Type 3 fonts (or with
|
---|
| 1755 | -preload).
|
---|
| 1756 | Extend FoFiType1 to handle Type 1 fonts with octal character codes in
|
---|
| 1757 | their encodings.
|
---|
| 1758 | Use a custom string formatter to avoid problems with locale-based decimal
|
---|
| 1759 | formatting (commas instead of periods) in PS output.
|
---|
| 1760 | Allow comments in PostScript-type functions.
|
---|
| 1761 | Change the TrueType font parser (FoFiTrueType) to delete glyf table
|
---|
| 1762 | entries that are too short.
|
---|
| 1763 |
|
---|
| 1764 | 3.03 (2011-aug-15)
|
---|
| 1765 | ------------------
|
---|
| 1766 | Added the "fixed pitch" text extraction mode.
|
---|
| 1767 | Modified "pdftops -paper match" to handle PDF files with
|
---|
| 1768 | different-sized pages, i.e., it will now select the matching paper
|
---|
| 1769 | size on a page-by-page basis.
|
---|
| 1770 | Add ability for pdftoppm to write to stdout.
|
---|
| 1771 | Added the pdfdetach tool.
|
---|
| 1772 | Implemented 256-bit AES decryption.
|
---|
| 1773 | Commented out the t1lib section in the configure script -- t1lib has
|
---|
| 1774 | some potential security holes, and hasn't been updated in years.
|
---|
| 1775 | Redesigned the font configuration xpdfrc commands: removed the
|
---|
| 1776 | displayFontT1, displayFontTT, displayNamedCIDFontT1,
|
---|
| 1777 | displayCIDFontT1, displayNamedCIDFontTT, displayCIDFontTT, psFont,
|
---|
| 1778 | psNamedFont16, and psFont16 commands; added the fontFile,
|
---|
| 1779 | fontFileCC, psResidentFont, psResidentFont16, and psResidentFontCC
|
---|
| 1780 | commands.
|
---|
| 1781 | Switched from GPLv2 to dual v2/v3 licensing.
|
---|
| 1782 | Performance: cache tiling patterns.
|
---|
| 1783 | Implemented text fills with pattern color spaces.
|
---|
| 1784 | Rewrote the image and image mask rendering code to be more accurate
|
---|
| 1785 | and faster.
|
---|
| 1786 | Fixed a bug in PDFCore that could sometimes cause crashes at high zoom
|
---|
| 1787 | levels.
|
---|
| 1788 | Implemented embedded CMap streams.
|
---|
| 1789 | Added the 'setSelection' command.
|
---|
| 1790 | Added the 'rotateCCW' and 'rotateCW' commands.
|
---|
| 1791 | Added the 'psFontPassthrough' xpdfrc command.
|
---|
| 1792 | Added the 'launchCommand' xpdfrc command.
|
---|
| 1793 | Implemented alpha-type soft masks.
|
---|
| 1794 | Added "Form: AcroForm|XFA|none" to pdfinfo output.
|
---|
| 1795 | Added support for image masks filled with pattern color spaces.
|
---|
| 1796 | Text search wasn't finding all occurrences of a string on rotated pages
|
---|
| 1797 | (i.e., pages where the primary rotation, as displayed, was not
|
---|
| 1798 | horizontal).
|
---|
| 1799 | The text extractor now uses "ActualText" spans if they are present.
|
---|
| 1800 | Modified PSOutputDev so it always check for transparency; if Splash is
|
---|
| 1801 | not available, it now prints a warning.
|
---|
| 1802 | Handle the blending color space for soft masks.
|
---|
| 1803 | Added the disableFreeTypeHinting xpdfrc option.
|
---|
| 1804 | Added the psAlwaysRasterize xpdfrc option.
|
---|
| 1805 | Added support for transfer functions in the rasterizer.
|
---|
| 1806 | Optimized the JPEG 2000 decoder to use less memory.
|
---|
| 1807 | Do fill adjustment (similar to stroke adjustment) on simple
|
---|
| 1808 | rectangular fills.
|
---|
| 1809 | Added the antialiasPrinting xpdfrc setting.
|
---|
| 1810 | Added '%i', '%j', and '%k' (mouse pointer page and position) to the
|
---|
| 1811 | available options for the 'run' command.
|
---|
| 1812 | Links with the underlined border style were being drawn with the lines
|
---|
| 1813 | over, instead of under, the text.
|
---|
| 1814 | Add #include <aconf.h> to XPDFTree.cc (to avoid problems with certain
|
---|
| 1815 | compilers).
|
---|
| 1816 | Change XRef::fetch() to avoid infinite loops caused by odd damage to
|
---|
| 1817 | the xref table (e.g., where a stream object's "Length" value is an
|
---|
| 1818 | indirect reference that points to another stream object).
|
---|
| 1819 | Minor fix in GString.cc to deal with an error in newer C++ compilers
|
---|
| 1820 | (pow() can take int or double args).
|
---|
| 1821 | Handle embedded fonts which are declared with the wrong font type,
|
---|
| 1822 | including 8-bit fonts declared as CID fonts and vice versa; this
|
---|
| 1823 | was causing various problems, including crashes and invalid
|
---|
| 1824 | PostScript output.
|
---|
| 1825 | In text extractor, don't drop horizontally overlapping words onto a
|
---|
| 1826 | separate line.
|
---|
| 1827 | The numbers in the operand to the TJ operator should be multiplied by
|
---|
| 1828 | the current horizontal scaling parameter.
|
---|
| 1829 | Fixed a bug in the Type 1C-to-Type 1 font converter -- need to escape
|
---|
| 1830 | strings in the font dictionary.
|
---|
| 1831 | The zero-font-size check in PSOutputDev.cc was broken.
|
---|
| 1832 | Fixes for the form field appearance regeneration code: handle Unicode
|
---|
| 1833 | strings (by downconverting to Latin1); check for "True" in addition
|
---|
| 1834 | to "Yes" as a button value.
|
---|
| 1835 | Modify XPDFTree to limit the widget height to 32767 pixels -- this
|
---|
| 1836 | avoids crashes with very large outlines.
|
---|
| 1837 | Modify FoFiType1 to handle PFB headers in Type 1 font files.
|
---|
| 1838 | Allow image mask decode arrays to be [1.0 0.0] in addition to [1 0].
|
---|
| 1839 | Tweak the form field appearance regeneration code.
|
---|
| 1840 | PSOutputDev now sets up resources for DR dictionaries in forms (in
|
---|
| 1841 | case the form field appearances are regenerated).
|
---|
| 1842 | For TrueType fonts which are marked symbolic, the cmaps should be
|
---|
| 1843 | ignored.
|
---|
| 1844 | Change the handling of numeric characters in Unicode text output --
|
---|
| 1845 | they are now treated as left-to-right, which isn't strictly correct,
|
---|
| 1846 | but does result in correct visual formatting.
|
---|
| 1847 | Modify FoFiTrueType to handle bogus loca table entries where the
|
---|
| 1848 | offset is past the end of the glyf table.
|
---|
| 1849 | Fixed shading pattern fills to do clipping and background fills
|
---|
| 1850 | correctly.
|
---|
| 1851 | Change the code that reads the page tree to be more flexible with
|
---|
| 1852 | regard to improperly constructed trees.
|
---|
| 1853 | Changed the PostScript header comment from "Produced by xpdf/pdftops
|
---|
| 1854 | x.yy" to "XpdfVersion: x.yy" to make it (mostly) DSC-compliant.
|
---|
| 1855 | Fixed PSOutputDev to handle page rotation correctly where the PDF page
|
---|
| 1856 | is rotated 90 or 270 degrees and the page width (before rotation) is
|
---|
| 1857 | greater than its height (and vice versa for 0 or 180 degrees).
|
---|
| 1858 | Unbalanced save/restores inside form XObjects (which can be happen in
|
---|
| 1859 | damaged or incorrectly constructed PDF files) could cause crashes.
|
---|
| 1860 | The CCITTFax decoder could go into an infinite loop on certain types
|
---|
| 1861 | of corrupt input.
|
---|
| 1862 | Added the "drawAnnotations" xpdfrc command.
|
---|
| 1863 | Added the "psUncompressPreloadedImages" xpdfrc command.
|
---|
| 1864 | Escape newlines and other non-printable characters in the custom color
|
---|
| 1865 | DSC comments in PostScript output.
|
---|
| 1866 | Added the tilingPatternFill and *ShadedFill functions to
|
---|
| 1867 | PreScanOutputDev to speed it up.
|
---|
| 1868 | Too many elements in an image's Decode array should not be a fatal
|
---|
| 1869 | error.
|
---|
| 1870 | Fixed a buffer overflow security hole in StreamPredictor.
|
---|
| 1871 | Empty pages (zero-length content streams and null contents) were
|
---|
| 1872 | causing crashes in continuous view mode.
|
---|
| 1873 | Handle line dash arrays that start with a zero element correctly.
|
---|
| 1874 | PreScanOutputDev was not correctly detecting all transparency - in
|
---|
| 1875 | some places, it was looking only at the blending mode, and not at
|
---|
| 1876 | the opacity setting.
|
---|
| 1877 | Force halftone screen size to be a power of 2. This allows optimizing
|
---|
| 1878 | the halftoning code.
|
---|
| 1879 | Fixed a bug in the JBIG2 MMR decoder (and also in the CCITTFax
|
---|
| 1880 | decoder) that was causing array references with negative indexes.
|
---|
| 1881 | Fixed a bug in the transparency code that was causing memory overruns.
|
---|
| 1882 | Fixed a 64-bit bug in the ASCII85 encoder.
|
---|
| 1883 | The focusToPageNum was crashing in full-screen mode - it should simply
|
---|
| 1884 | do nothing.
|
---|
| 1885 | Added '%p' (current page number) to the available options for the 'run'
|
---|
| 1886 | command.
|
---|
| 1887 | Tweak the behavior with PDF files that have pages of different widths
|
---|
| 1888 | in continuous mode: scroll horizontally to avoid blank space on the
|
---|
| 1889 | left side (when changing pages via entering a page number or
|
---|
| 1890 | clicking on a link).
|
---|
| 1891 | A closepath followed by a lineto should create a new subpath for the
|
---|
| 1892 | lineto.
|
---|
| 1893 | Fixed a buffer overflow in the CCITTFax decoder.
|
---|
| 1894 | Adobe Acrobat appears to ignore the flatness setting when rasterizing
|
---|
| 1895 | curves, so Xpdf now does the same. (Oddly, Acrobat passes the
|
---|
| 1896 | flatness setting through to PostScript output, which ends up making
|
---|
| 1897 | the PS file look different from the PDF file - so Xpdf continues to
|
---|
| 1898 | pass flatness through to PS files, too.)
|
---|
| 1899 | Pdfimages now ignores tiling pattern fills (for performance reasons).
|
---|
| 1900 | Fixed a bug in PDFCore that could sometimes cause crashes at high zoom
|
---|
| 1901 | levels.
|
---|
| 1902 | Use std::sort (with functors) in place of qsort (if available) - this
|
---|
| 1903 | can be significantly faster.
|
---|
| 1904 | Hitting "close" while Xpdf is in full-screen mode (with only one file
|
---|
| 1905 | open) was crashing.
|
---|
| 1906 | Tweak the TrueType font encoding deciphering algorithm.
|
---|
| 1907 | Rewrote the CCITTFax decoder inner loop - this fixes a security hole.
|
---|
| 1908 | Fixed two security holes (missing bounds checks) in the DCT decoder.
|
---|
| 1909 | Do the correct zooming for "Fit" and "FitR" destinations.
|
---|
| 1910 | Implement the rotation value in the form field appearance regeneration
|
---|
| 1911 | code.
|
---|
| 1912 | When PSOutputDev rasterizes a page (because it contains transparency),
|
---|
| 1913 | the image is broken into stripes if it is above a size threshold.
|
---|
| 1914 | Don't clip the other page boxes to the MediaBox at the intermediate
|
---|
| 1915 | (Pages) nodes; only do it at the leaf (Page) nodes - the other boxes
|
---|
| 1916 | can be specified before the MediaBox is specified.
|
---|
| 1917 | Split several special cases off from Splash::pipeRun, for performance.
|
---|
| 1918 | Add a sanity check for excessively large font sizes (which caused
|
---|
| 1919 | problems because Xpdf tried to allocate memory for a font cache).
|
---|
| 1920 | Fixed a bug in the GfxCIDFont constructor involving reading the
|
---|
| 1921 | vertical metrics.
|
---|
| 1922 | Rewrote the code that handles annotation transforms - it was not
|
---|
| 1923 | handling non-rectangular transforms correctly.
|
---|
| 1924 | Tweak the Type 3 bbox code to allow some slack on the left/bottom
|
---|
| 1925 | edges, as well as the top/right edges.
|
---|
| 1926 | Fixed a bug that was causing problems rendering Type 3 fonts to 1-bit
|
---|
| 1927 | monochrome output.
|
---|
| 1928 | Handle the case where AES padding is invalid.
|
---|
| 1929 | Changed XRef::getNumObjects to return the number of used entries,
|
---|
| 1930 | instead of the same value as returned by XRef::getSize().
|
---|
| 1931 | Ignore bogus entries in the TrueType table directory instead of
|
---|
| 1932 | immediately giving up on the font.
|
---|
| 1933 | Fixed a bug in the radial shading code that could cause divide-by-zero
|
---|
| 1934 | errors.
|
---|
| 1935 | Tweaked the TrueType font fixup code to deal with an extra zero entry
|
---|
| 1936 | at the end of the loca table.
|
---|
| 1937 | Increased font cache sizes to improve performance.
|
---|
| 1938 | Tweaked the TrueType notdef kludge to skip the notdef glyph only if it
|
---|
| 1939 | was caused by a character for which a Unicode/MacRoman mapping could
|
---|
| 1940 | not be found.
|
---|
| 1941 | Added another font size sanity check, this time for Type 3 glyphs.
|
---|
| 1942 | Added initial support for optional content (layers) - no GUI yet.
|
---|
| 1943 | For CID fonts that specify the 'Adobe-Identity' or 'Adobe-UCS'
|
---|
| 1944 | collection, use an identity mapping for char code-to-Unicode
|
---|
| 1945 | conversion.
|
---|
| 1946 | Updated the error function to take a category argument, and to use
|
---|
| 1947 | GString::format instead of printf; added an error callback.
|
---|
| 1948 | The PDF spec claims that names are limited to 127 chars, but Distiller
|
---|
| 1949 | 8 will produce longer names, and Acrobat 8 will accept longer names
|
---|
| 1950 | -- Xpdf will now handle them, too.
|
---|
| 1951 | Change the Catalog code so it doesn't load the entire page tree at
|
---|
| 1952 | startup (this only helps the command line tools - the viewer scans
|
---|
| 1953 | all of the pages at startup).
|
---|
| 1954 | Clip opacity values to the range [0,1].
|
---|
| 1955 | Handle glyph names of the form 'unixxxx' (similar to Ann, Axx, etc.).
|
---|
| 1956 | Resolution of rasterized pages in PostScript output was not being
|
---|
| 1957 | computed correctly (resulting in overly large images).
|
---|
| 1958 | Extend the mapUnknownCharNames config command to cover CID fonts.
|
---|
| 1959 | Zero-length segments in the middle of stroked paths were not being
|
---|
| 1960 | handled correctly -- they should be completely ignored, except for
|
---|
| 1961 | the special case of a zero-length path with round line caps.
|
---|
| 1962 | Various optimizations to the Splash rasterizer.
|
---|
| 1963 | Allow "Identity" and "Default" as the transfer function in soft masks.
|
---|
| 1964 | Tweaked the ToUnicode CMap parser to allow <00xx> char codes for 8-bit
|
---|
| 1965 | fonts.
|
---|
| 1966 | TextPage::clear() was not clearing the lists of underlines and links.
|
---|
| 1967 | Changed the CCITTFax decoder to correctly handle the interaction
|
---|
| 1968 | between the EndOfLine and EncodedByteAlign parameters.
|
---|
| 1969 | Fixed a bug where xpdf wouldn't go to a destination specified on the
|
---|
| 1970 | command line, if continuous mode was enabled
|
---|
| 1971 | (xpdf -cont file.pdf +foo).
|
---|
| 1972 | Fixed a bug in the FreeType interface code which was causing incorrect
|
---|
| 1973 | positioning/sizing of characters.
|
---|
| 1974 | Tweaked the FreeType interface code - use 'light' hinting with Type 1
|
---|
| 1975 | fonts (because it generally looks better).
|
---|
| 1976 | Tweak the Windows font searching code to handle "Black" fonts.
|
---|
| 1977 | Fixed a bug in the PostScript-type function parser -- real numbers
|
---|
| 1978 | that start with a decimal point weren't being handled correctly.
|
---|
| 1979 | Changed the way filled-and-stroked text is handled -- use Splash to do
|
---|
| 1980 | both the fill and the stroke (rather than using the font ending to
|
---|
| 1981 | do the fill and Splash to do the stroke); also turn off stroke
|
---|
| 1982 | adjustment when drawing stroked text.
|
---|
| 1983 | Ignore generation numbers on compressed objects (to match Adobe's
|
---|
| 1984 | behavior).
|
---|
| 1985 | Changed the PostScript PageSize policy from 3 to 6 (choose next
|
---|
| 1986 | largest paper size, don't rescale).
|
---|
| 1987 | Check that the mask values for color key masked images are in range --
|
---|
| 1988 | both Ghostscript and Distiller choke on the PostScript if invalid
|
---|
| 1989 | mask colors are specified.
|
---|
| 1990 | Fixed a bug in generic region decoding in the JBIG2 decoder.
|
---|
| 1991 | Fixed the lexer to handle large real numbers correctly.
|
---|
| 1992 | Pdftops wasn't correctly handling tiling patterns that use both fill
|
---|
| 1993 | and stroke operators.
|
---|
| 1994 | Report an error if the Size array in a sampled function includes any
|
---|
| 1995 | zeros.
|
---|
| 1996 | The PostScriptFunction.codeString field wasn't being initialized
|
---|
| 1997 | correctly.
|
---|
| 1998 | Invalid object streams were not being handled correctly.
|
---|
| 1999 | Check for loops in xref tables.
|
---|
| 2000 | Handle the case where a content stream ends after the 'ID' operator
|
---|
| 2001 | which starts inline image data.
|
---|
| 2002 | Check for invalid object streams (i.e., an object stream can't be
|
---|
| 2003 | inside another object stream.
|
---|
| 2004 | Add a recursion limit to the object parser - this avoids stack
|
---|
| 2005 | overflows with various sorts of damaged PDF files.
|
---|
| 2006 | Handle various parameter settings in the extended graphics state
|
---|
| 2007 | dictionary.
|
---|
| 2008 | An invalid document outline (missing fields) could cause a crash.
|
---|
| 2009 | Added an overprint preview mode (for CMYK output only).
|
---|
| 2010 | Correctly handle FitH/BH/V/BV link destinations that contain null
|
---|
| 2011 | values for positioning parameters.
|
---|
| 2012 | If the PDF file doesn't define a BaseURI, set one based on the
|
---|
| 2013 | location of the PDF file -- this allows relative links to be handled
|
---|
| 2014 | correctly.
|
---|
| 2015 | Use ResusableStreamDecode when generating Level 3 PostScript for an
|
---|
| 2016 | explicitly masked image.
|
---|
| 2017 | Tweak the Type 1 font parser to handle encodings with multiple
|
---|
| 2018 | characters on one line.
|
---|
| 2019 | Invert subtractive color components before passing them to the
|
---|
| 2020 | blending function.
|
---|
| 2021 | Fix an invalid array access in SplashOutputDev::setSoftMask() in CMYK
|
---|
| 2022 | mode.
|
---|
| 2023 | A PS interpreter may attempt to read past the end of a preloaded
|
---|
| 2024 | image, so we need to check for that.
|
---|
| 2025 | Fixed several overflow/uninit bugs in JBIG2Stream.
|
---|
| 2026 | Fix the CCITTFax decoder to correctly find end-of-file (RTC/EOFB)
|
---|
| 2027 | markers when the EndOfLine parameter is false.
|
---|
| 2028 | Don't limit the startxref offset to 10 digits - some PDF generators
|
---|
| 2029 | use extra leading zeros.
|
---|
| 2030 | Use the "DV" (default value) field in text annotations if the "V"
|
---|
| 2031 | (value) field is missing.
|
---|
| 2032 | Increase the number of digits printed for floating point numbers in
|
---|
| 2033 | PostScript output -- it was running into numerical accuracy problems
|
---|
| 2034 | on large pages.
|
---|
| 2035 | Fixed integer overflow bugs in Catalog.cc and GfxFont.cc.
|
---|
| 2036 | Zero-length tables in TrueType fonts should be treated as missing.
|
---|
| 2037 | ToUnicode CMaps map char codes to Unicode; .cidToUnicode files map
|
---|
| 2038 | CIDs to Unicode -- ToUnicodeCMaps were being handled incorrectly.
|
---|
| 2039 | Added the "psRasterResolution" and "psRasterMono" xpdfrc commands.
|
---|
| 2040 | Added code to FoFiTrueType to check for entries in the table directory
|
---|
| 2041 | with bogus tags -- this handles the case where the number of tables
|
---|
| 2042 | given in the header is too high.
|
---|
| 2043 | Negative shift values in the PostScript bitshift operator were being
|
---|
| 2044 | handled incorrectly.
|
---|
| 2045 | GfxICCBasedColorSpace was not correctly bounds-checking the number of
|
---|
| 2046 | components.
|
---|
| 2047 | Check SampledFunction input values for NaNs.
|
---|
| 2048 | Fix a divide-by-zero when the page width or height is zero.
|
---|
| 2049 | Fix a bug positioning text in PostScript output - if the last char in
|
---|
| 2050 | a string has an incorrect width in the PDF font object, that messes
|
---|
| 2051 | up the total string width, so we have to position individual chars.
|
---|
| 2052 | In PostScript output, if CID font substitution fails, drop all text in
|
---|
| 2053 | that font.
|
---|
| 2054 | Handle PDF files that set the stream/string decryption filters to
|
---|
| 2055 | Identity (i.e., no encryption).
|
---|
| 2056 | Avoid passing a zero font size to FreeType.
|
---|
| 2057 | Tweak raw mode in the text extractor to handle words on the same line
|
---|
| 2058 | drawn in the wrong order.
|
---|
| 2059 | Pdftops was generating a singular transform matrix for annotations
|
---|
| 2060 | whose bounding boxes had zero width or height.
|
---|
| 2061 | Handle embedded OpenType CFF fonts with CIDToGIDMaps.
|
---|
| 2062 | Remove the old kludge from PSOutputDev that was converting char 32
|
---|
| 2063 | from ".notdef" to "space".
|
---|
| 2064 | Allow CCITTFax images to be more than 32k pixels wide.
|
---|
| 2065 | Modified the CMap parser to handle usecmap with Identity-H/V.
|
---|
| 2066 | Added some parameter checking in the JPX decoder.
|
---|
| 2067 | Added checks for infinite loops in PDF objects - for color spaces,
|
---|
| 2068 | functions, optional content, and outline items.
|
---|
| 2069 | Add support for mouse button bindings up to button 32 (old limit was
|
---|
| 2070 | 7).
|
---|
| 2071 | Fixed a bug in the decryption code for revision 3 with keyLength < 16
|
---|
| 2072 | -- the owner password was not being handled correctly. [Thanks to
|
---|
| 2073 | Matthias Franz.]
|
---|
| 2074 | Optimize SampledFunction: pull index computation code out of the
|
---|
| 2075 | transform function; cache the last transform.
|
---|
| 2076 | Tweaked the font naming algorithm in PSOutputDev.
|
---|
| 2077 | Treat mirrored (as opposed to rotated) text the same as upright text
|
---|
| 2078 | in pdftotext.
|
---|
| 2079 | Fixed buffer overflows in Splash and SplashBitmap.
|
---|
| 2080 | Check for bogus character codes (e.g., <ffffffff>) in ToUnicode CMaps.
|
---|
| 2081 | The radial shading code (in both Gfx.cc and PSOutputDev.cc) was not
|
---|
| 2082 | computing the s bounds properly.
|
---|
| 2083 | Drop empty subpaths in clip and fill (but not stroke) operations -
|
---|
| 2084 | this can significantly speed up clip performance in the weird case
|
---|
| 2085 | where a PDF file does "<x> <y> <w> <h> re <x> <y> m h W n".
|
---|
| 2086 | Added code to FoFiTrueType to check for an invalid loca format field
|
---|
| 2087 | in the head table.
|
---|
| 2088 | The axial shading code (in Gfx.cc, but not PSOutputDev.cc) was not
|
---|
| 2089 | computing the incremental polygon vertices correctly.
|
---|
| 2090 | Set the character width in TextOutputDev to something sensible for
|
---|
| 2091 | vertical fonts.
|
---|
| 2092 | Added basic support to the text extractor for vertical writing mode.
|
---|
| 2093 | The non-interactive tools (pdftotext, pdftops) now free Page objects
|
---|
| 2094 | after using them, avoiding performance problems with pages that have
|
---|
| 2095 | huge resource dictionaries.
|
---|
| 2096 | Check for line dash arrays like [0], and draw nothing at all (to match
|
---|
| 2097 | Acrobat's behavior).
|
---|
| 2098 | Add a sanity check for the ascent/descent values in FontDescriptors.
|
---|
| 2099 | Single-point paths with a line dash were causing a crash.
|
---|
| 2100 | Correctly handle Level 3 PostScript output with masked images inside
|
---|
| 2101 | patterns.
|
---|
| 2102 | Tweaked the xref repair code so that it runs if the catalog is messed
|
---|
| 2103 | up (in addition to running if the xref table is damaged).
|
---|
| 2104 | If Indexed color space tables (streams or strings) are too small,
|
---|
| 2105 | reduce the max index instead of throwing away the color space.
|
---|
| 2106 | Change the CMap parser to allocate memory only when it sees a mapping,
|
---|
| 2107 | not when it sees a 'codespacerange' declaration -- this avoids
|
---|
| 2108 | allocating huge amounts of memory for CMaps with large, unused
|
---|
| 2109 | codespaceranges.
|
---|
| 2110 | In monochrome mode, treat lines with width <= 1 as hairlines (to match
|
---|
| 2111 | Acrobat's behavior).
|
---|
| 2112 | Cache the last transform for PostScript-type functions.
|
---|
| 2113 | Added the "-rawdates" option to pdfinfo.
|
---|
| 2114 | Optimized ImageStream::getLine().
|
---|
| 2115 | Fixed the Hue, Saturation, Color, and Luminosity blend functions to
|
---|
| 2116 | match Adobe's spec.
|
---|
| 2117 | Fixed the non-isolated group compositing computation.
|
---|
| 2118 | Skip extraneous unused data at the end of JBIG2 segments.
|
---|
| 2119 | Change the algorithm that stroke/fill adjustment uses so that the
|
---|
| 2120 | edges of adjacent strokes/fills line up.
|
---|
| 2121 | Do stroke adjustment on end caps when cap style is butt or projecting.
|
---|
| 2122 | Fixed a security hole: Gfx.parser was not being initialized to NULL.
|
---|
| 2123 | Fixed a security hole: integer bounds check in the Type 1 encoding
|
---|
| 2124 | parser in FoFiType1.cc.
|
---|
| 2125 | If an embedded font object is invalid or non-existent, do font
|
---|
| 2126 | substitution (same as if there were no embedded font).
|
---|
| 2127 | TextOutputDev was reusing an old font in the case where the font
|
---|
| 2128 | changed but the font size and character positioning stayed the same.
|
---|
| 2129 | When starting a transparency group, copy the fill/stroke colors from
|
---|
| 2130 | the graphics state.
|
---|
| 2131 | Tweaked the fixed-point code.
|
---|
| 2132 | When a TrueType font is declared resident (with a psFont command),
|
---|
| 2133 | don't munge the encoding.
|
---|
| 2134 | Look for URIs starting with "www." and treat them as absolute "http:"
|
---|
| 2135 | URIs, not as relative URIs (to match Adobe's behavior).
|
---|
| 2136 | Added code to FoFiTrueType to check for a zero-entry cmap table.
|
---|
| 2137 | Tweaked the font substitution code to do a better job of scaling the
|
---|
| 2138 | substituted font.
|
---|
| 2139 | Require at least two splits in the axial shading color bisection.
|
---|
| 2140 | Optimized JBIG2Stream::readGenericBitmap().
|
---|
| 2141 | JPXStream wasn't correctly handling row padding for images with fewer
|
---|
| 2142 | than 8 bits per component.
|
---|
| 2143 | Optimized the ToUnicode CMap parser.
|
---|
| 2144 | Added a "whole words only" option to text searches.
|
---|
| 2145 | Check for valid component parameters in the DCT decoder.
|
---|
| 2146 | Implement embedding of external 16-bit fonts (without subsetting) in
|
---|
| 2147 | PostScript output.
|
---|
| 2148 | Added the minLineWidth xpdfrc command.
|
---|
| 2149 | Added warning messages for font substitutions.
|
---|
| 2150 |
|
---|
| 2151 | 3.04 (2014-may-28)
|
---|
| 2152 | ------------------
|
---|
| 2153 | New text extractor.
|
---|
| 2154 | Added the pdftohtml tool.
|
---|
| 2155 | Added the pdftopng tool.
|
---|
| 2156 | New trapezoid-based rasterizer core (for performance).
|
---|
| 2157 | Generate appearance streams for Line, PolyLine, and Polygon
|
---|
| 2158 | annotations.
|
---|
| 2159 | Added the closeWindowOrQuit command, and changed the default binding
|
---|
| 2160 | for ctrl-W from closeWindow to closeWindowOrQuit.
|
---|
| 2161 | Implemented the new AES-256 mode (R=6, Acrobat X).
|
---|
| 2162 | Add an object cache.
|
---|
| 2163 | Added a small cache for object streams.
|
---|
| 2164 | Modify PSOutputDev to use LZW compression instead of RLE, with a
|
---|
| 2165 | fallback to RLE if the "psLZW no" setting is given.
|
---|
| 2166 | Pdfinfo now prints page rotation info.
|
---|
| 2167 | Modified ImageOutputDev, used by pdfimages, to output the masks and
|
---|
| 2168 | soft masks used when drawing images.
|
---|
| 2169 | Remove non-printable characters from error output, just in case they
|
---|
| 2170 | might cause problems for the terminal program.
|
---|
| 2171 | Added initial support for Code3of9 bar codes in XFA forms.
|
---|
| 2172 | Added the mapExtTrueTypeFontsViaUnicode xpdfrc command.
|
---|
| 2173 | Apply stroke adjustment to rectangular images and clipping regions (in
|
---|
| 2174 | addition to strokes and fills).
|
---|
| 2175 | Decode JPEG 2000 images at less than full resolution if the full res
|
---|
| 2176 | image isn't needed (i.e., if the raw image is higher resolution than
|
---|
| 2177 | the output).
|
---|
| 2178 | Implemented knockout groups.
|
---|
| 2179 | Removed t1lib support.
|
---|
| 2180 | Added support for images with 16-bit components.
|
---|
| 2181 | Rewrote the Dict class to use a hash table; as a side effect, this
|
---|
| 2182 | handles dictionaries with multiple definitions for a key, which are
|
---|
| 2183 | in violation of the spec, but Acrobat appears to handle.
|
---|
| 2184 | The transformed line width computation -- used to implement the
|
---|
| 2185 | minLineWidth setting, and the hairline threshold in monochrome mode --
|
---|
| 2186 | was incorrect.
|
---|
| 2187 | Pdftops was not correctly handling the case where it couldn't find
|
---|
| 2188 | a 16-bit font -- this led to crashes and/or invalid PostScript.
|
---|
| 2189 | A bug in FlateStream::getBlock() was causing problems with narrow
|
---|
| 2190 | images.
|
---|
| 2191 | Use the correct _WIN32 define instead of WIN32.
|
---|
| 2192 | Use copy-on-write for the clip path in SplashState (when doing gsave),
|
---|
| 2193 | for performance.
|
---|
| 2194 | Added a Solaris-specific entry to the ghostscript font search path.
|
---|
| 2195 | SplashState was initializing line width to 0 instead of 1.
|
---|
| 2196 | Abort processing on a content stream after getting 500 errors
|
---|
| 2197 | (undefined operator, wrong number of args) -- this avoids very long
|
---|
| 2198 | processing time for malicious PDF files using bogus RLE encoded
|
---|
| 2199 | content streams.
|
---|
| 2200 | Added the psUseCropBoxAsPage xpdfrc option; "pdftops -pagecrop" now
|
---|
| 2201 | sets psUseCropBoxAsPage; "pdftops -pagecrop -paper match" now uses
|
---|
| 2202 | the CropBox as the page size.
|
---|
| 2203 | Re-architected the AcroForm support code into a separate AcroForm
|
---|
| 2204 | module.
|
---|
| 2205 | Fixed the handling of overprinting/transparency interaction, using
|
---|
| 2206 | the CompatibleOverprint blend mode.
|
---|
| 2207 | The TIFF predictor code for the 1-bit-per-pixel case was broken.
|
---|
| 2208 | For triangle and patch mesh shadings (types 4-7) with color functions,
|
---|
| 2209 | interpolate the function parameter not the color.
|
---|
| 2210 | Check the fontFile/fontDir commands before (instead of after) doing
|
---|
| 2211 | Base-14 substitution in PS output.
|
---|
| 2212 | Correctly handle non-embedded TrueType fonts that have an Identity
|
---|
| 2213 | ToUnicode mapping (display and PS output were failing).
|
---|
| 2214 | Added support for XFA form rendering, including an "enableXFA" xpdfrc
|
---|
| 2215 | setting.
|
---|
| 2216 | Handle PFB Type 1 fonts when generating PostScript output.
|
---|
| 2217 | Unwind any extraneous saved graphics state at the end of the page
|
---|
| 2218 | (before drawing annotations).
|
---|
| 2219 | Added some integer overflow checks in the GString class.
|
---|
| 2220 | Handle 16-bit components in JPEG 2000 images.
|
---|
| 2221 | ActualText spans can end without a valid font, in which case
|
---|
| 2222 | TextPage::beginWord was crashing.
|
---|
| 2223 | The Domain entry in function shadings wasn't being parsed correctly.
|
---|
| 2224 | Fixed a bug in the JPEG decoder - successive approximation
|
---|
| 2225 | (progressive mode) coefficients weren't being handled correctly.
|
---|
| 2226 | Added a better infinite loop test to the xref parser.
|
---|
| 2227 | When generating PostScript, merge reused TrueType fonts (if their
|
---|
| 2228 | code-to-GID mappings are the same).
|
---|
| 2229 | Tweak the Gouraud triangle shaded fill code to end the recursive
|
---|
| 2230 | splitting if the triangles get sufficiently small.
|
---|
| 2231 | Do bilinear interpolation when upsampling images.
|
---|
| 2232 | When skipping extraneous image data from an inline image, look for
|
---|
| 2233 | EI<whitespace> instead of just EI.
|
---|
| 2234 | When writing to stdout on Windows, pdftoppm now sets the file mode to
|
---|
| 2235 | binary. [Thanks to Robert Frunzke.]
|
---|
| 2236 | Accept strings as well as names for the BaseFont entry in font
|
---|
| 2237 | objects.
|
---|
| 2238 | Removed the TEXTOUT_WORD_LIST config option (with the new text
|
---|
| 2239 | extractor, this is always enabled).
|
---|
| 2240 | Fixed a bug in the JBIG2 decoder (the TPGD context for template #3 in
|
---|
| 2241 | readGenericBitmap was incorrect).
|
---|
| 2242 | Rewrote the PostScriptFunction code for performance.
|
---|
| 2243 | Handle 8-bit OpenType CFF fonts that are missing required tables in
|
---|
| 2244 | the OpenType wrapper.
|
---|
| 2245 | Handle tiling patterns with reversed coordinates in their bounding
|
---|
| 2246 | boxes.
|
---|
| 2247 | Added support for 64-bit file offsets, i.e., PDF files larger than
|
---|
| 2248 | 2GB.
|
---|
| 2249 | Optimize the code that rasterizes pattern-filled image masks.
|
---|
| 2250 | Added support for Mac OS X system fonts (Base-14 only).
|
---|
| 2251 | The backdrop color in luminosity-type soft mask groups was not being
|
---|
| 2252 | handled correctly.
|
---|
| 2253 | Modified behavior of "pdftops -paper match -duplex ..." - it will now
|
---|
| 2254 | duplex consecutive same-sized pages.
|
---|
| 2255 | Tweak the handling of degenerate fills ('moveto lineto fill') to
|
---|
| 2256 | match Adobe.
|
---|
| 2257 | Don't honor the OPM=1 setting with ICCBased CMYK color spaces.
|
---|
| 2258 | Whole-word searches were treating certain punctuation (Unicode number
|
---|
| 2259 | separators and terminators) as part of the word, e.g., searching for
|
---|
| 2260 | "foo" would not match "foo,".
|
---|
| 2261 | Use the TextString class everywhere it makes sense.
|
---|
| 2262 | Removed the unnecessary segment sort in Splash (performance
|
---|
| 2263 | optimization).
|
---|
| 2264 | Handle hyperlinks that use Widget-type annotations.
|
---|
| 2265 | Fix up the integer overflow checks to avoid issues with clever
|
---|
| 2266 | compilers. [Thanks to Nickolai Zeldovich.]
|
---|
| 2267 | Correctly handle streams with missing Length entries in damaged PDF
|
---|
| 2268 | files.
|
---|
| 2269 | Added a compile-time option (LOAD_FONTS_FROM_MEM) to load fonts from
|
---|
| 2270 | memory rather than temporary files on disk.
|
---|
| 2271 | Added the psRasterSliceSize xpdfrc option.
|
---|
| 2272 | Fixed a case in the JPEG 2000 arithmetic decoder where extra data is
|
---|
| 2273 | present in packet i, and needs to be saved for use in packet i+1.
|
---|
| 2274 | Fixed a bug in the JPEG 2000 decoder related to images with fewer than
|
---|
| 2275 | 8 bits per component.
|
---|
| 2276 | Handle the case in PSOutputDev where slice size overflows a 32-bit
|
---|
| 2277 | integer.
|
---|
| 2278 | Add (partial) support for TrueType cmap format 2.
|
---|
| 2279 | Always pass FT_LOAD_NO_BITMAP to FreeType -- bitmaps apparently fail
|
---|
| 2280 | with rotated characters.
|
---|
| 2281 | Support fonts specified in ExtGState dictionaries.
|
---|
| 2282 | Annotations with empty Border arrays should not draw a border.
|
---|
| 2283 | Fix the CMap parser to handle large CID ranges.
|
---|
| 2284 | Check for Type 3 CharProcs that call q or Q before the d0/d1 operator,
|
---|
| 2285 | and treat them as uncacheable.
|
---|
| 2286 | Invert the selection color when starting in reverse video mode.
|
---|
| 2287 | Device{Gray,RGB,CMYK} cannot be mapped via a resource dict.
|
---|
| 2288 | Changed the PS output for masked images (explicit and color key
|
---|
| 2289 | masking): use a plain old clip path instead of rectclip to avoid
|
---|
| 2290 | array overflows.
|
---|
| 2291 | Check the StemSnapH/V arrays when converting Type 1C fonts to Type 1 -
|
---|
| 2292 | if there are any duplicate or out-of-order values, skip that
|
---|
| 2293 | StemSnapH/V array.
|
---|
| 2294 | Added the psMinLineWidth xpdfrc setting.
|
---|
| 2295 | Fix an obscure issue in converting TrueType fonts to Type 42, related
|
---|
| 2296 | to empty glyph descriptions (12 zero bytes).
|
---|
| 2297 | Pdftops now reports an error if there were any I/O errors writing to
|
---|
| 2298 | the PS output file.
|
---|
| 2299 | Fix vertical text (CJK fonts) in PS output -- offset the character
|
---|
| 2300 | origin correctly.
|
---|
| 2301 | Increased the number of digits used by pdfimages for the image number
|
---|
| 2302 | from three to four.
|
---|
| 2303 | Handle right-to-left (e.g., Arabic) ligatures correctly in the text
|
---|
| 2304 | extractor.
|
---|
| 2305 | Added the -loc and -locPS options to pdffonts.
|
---|
| 2306 | Extend the object parser recursion limit to cover Stream::addFilters()
|
---|
| 2307 | / Stream::makeFilters() - to avoid another possibility of stack
|
---|
| 2308 | overflow.
|
---|
| 2309 | Disable FreeType autohinting, because it can fail badly with font
|
---|
| 2310 | subsets that use invalid glyph names -- except in the case of Type 1
|
---|
| 2311 | fonts, which look much better with light autohinting.
|
---|
| 2312 | Modified the rasterizer pipeline functions to process a scan line at a
|
---|
| 2313 | time (for performance).
|
---|
| 2314 | Removed VMS build support (it hasn't been updated in ages).
|
---|
| 2315 | Removed pdftotext's '-htmlmeta' option (use pdftohtml instead).
|
---|
| 2316 | PSOutputDev's font/form setup code, and pdffonts, were not scanning
|
---|
| 2317 | soft mask groups in ExtGState dictionaries.
|
---|
| 2318 | Invalid DCT input (e.g., from a damaged PDF file) could overflow the
|
---|
| 2319 | dctClip array.
|
---|
| 2320 | When upsampling an image mask or image with a large resulting image
|
---|
| 2321 | size, do it in stream mode instead of prescaling the whole image
|
---|
| 2322 | (to avoid running out of memory).
|
---|
| 2323 | Added infinite loop detection to pdffonts.
|
---|
| 2324 |
|
---|
| 2325 | 4.00 (2017-aug-10)
|
---|
| 2326 | ------------------
|
---|
| 2327 | Complete rewrite of the xpdf GUI, using Qt instead of Motif.
|
---|
| 2328 | Multithreaded rasterization in the viewer - pages are now rasterized
|
---|
| 2329 | in a separate thread so that scrolling and other UI activity is not
|
---|
| 2330 | blocked.
|
---|
| 2331 | Added a linear text selection mode.
|
---|
| 2332 | Limit transparency groups to the clip rectangle (performance
|
---|
| 2333 | optimization).
|
---|
| 2334 | Optimized the SplashScreen code, used in 1-bit monochrome mode.
|
---|
| 2335 | Added setmode calls to pdftopng, when writing to stdout on Windows.
|
---|
| 2336 | [Thanks to Robert Schroll.]
|
---|
| 2337 | Regenerate the appearance stream for an AcroForm field if there is
|
---|
| 2338 | no appearance stream, even if NeedAppearances isn't set.
|
---|
| 2339 | When regenerating AcroForm field appearance streams, use a default
|
---|
| 2340 | font (Helvetica) for fields that don't have a valid font.
|
---|
| 2341 | When the line width is increased by the minLineWidth setting, force
|
---|
| 2342 | the line join mode to "bevel" to avoid "whiskers" at sharp corners.
|
---|
| 2343 | Change the pdftoppm/pdftopng resolution (-r) argument from an integer
|
---|
| 2344 | to floating point.
|
---|
| 2345 | Use the FontDescriptor 'CapHeight' value in place of 'Ascent' if it's
|
---|
| 2346 | available.
|
---|
| 2347 | OC (optional content) entries in image XObjects were being ignored.
|
---|
| 2348 | Added support for preblended soft-masked images.
|
---|
| 2349 | Added optional support for using libjpeg to decode DCT (JPEG)
|
---|
| 2350 | streams.
|
---|
| 2351 | Transparency groups weren't being composited correctly in mono1 mode.
|
---|
| 2352 | Switched to a different IDCT transform in the DCT (JPEG) decoder, to
|
---|
| 2353 | get better accuracy; the new transform is also a bit faster.
|
---|
| 2354 | Modified the polygon scan converter to avoid O(n^2) performance, which
|
---|
| 2355 | can get really bad with paths that have extremely large numbers of
|
---|
| 2356 | segments.
|
---|
| 2357 | Added the maxTileWidth, maxTileHeight, tileCacheSize, and
|
---|
| 2358 | workerThreads xpdfrc settings.
|
---|
| 2359 | Modified PSOutputDev so it doesn't output resources (fonts, etc.) for
|
---|
| 2360 | pages that are rasterized (because they use transparency).
|
---|
| 2361 | Added the -alpha flag to pdftopng.
|
---|
| 2362 | Handle TrueType fonts with out-of-bounds loca entries.
|
---|
| 2363 | Optimize consectutive "q" (gsave) operations in PostScript output.
|
---|
| 2364 | Various improvements to the XFA rendering code.
|
---|
| 2365 | Added the -nodiag flag to pdftotext.
|
---|
| 2366 | Switched to cmake instead of autoconf.
|
---|
| 2367 | Look for Widget-type annotations that aren't attached to the
|
---|
| 2368 | AcroForm, and add them to the AcroForm.
|
---|
| 2369 | Added the "-z" option to pdftohtml.
|
---|
| 2370 | The JPEG 2000 decoder now treats invalid boxes after the image
|
---|
| 2371 | codestream as non-fatal errors.
|
---|
| 2372 | Improved the handling of drop caps in pdftohtml.
|
---|
| 2373 | Added the "psNeverRasterize" setting.
|
---|
| 2374 | Pdftohtml now converts invisible PDF text to transparent HTML text.
|
---|
| 2375 | Check for zero-width/height bitmaps in the JBIG2 decoder -- these can
|
---|
| 2376 | happen in corrupted JBIG2 streams.
|
---|
| 2377 | Pdfimages was inverting 1-bit monochrome images.
|
---|
| 2378 | Added CCITTFaxStream::getBlock() to speed up the CCITTFax decoder.
|
---|
| 2379 | Added resolution info to PNG files generated by pdftopng.
|
---|
| 2380 | The DCT decoder now ignores non-Adobe APP14 markers (rather than
|
---|
| 2381 | generating an error).
|
---|
| 2382 | Regenerate appearance streams for FreeText annotations.
|
---|
| 2383 | The TextString class now handles UTF-16LE in addition to UTF-16BE.
|
---|
| 2384 | (UTF-16LE isn't allowed by the PDF spec, but I've seen it used.)
|
---|
| 2385 | Added the simple one-column text extraction mode (pdftotext -simple).
|
---|
| 2386 | Added a -cmyk option to pdftoppm to write CMYK PAM files.
|
---|
| 2387 | Modified pdfinfo to output "static XFA" or "dynamic XFA", rather than
|
---|
| 2388 | just "XFA".
|
---|
| 2389 | Added the "drawFormFields" xpdfrc command.
|
---|
| 2390 | Various performance optimizations in the rasterizer.
|
---|
| 2391 | Fixed the tiling pattern code to avoid stripes between pattern cells,
|
---|
| 2392 | and to honor the TilingType flag.
|
---|
| 2393 | Always split axial shadings into 256 slices.
|
---|
| 2394 | Handle the case where an optional content block is left open at the
|
---|
| 2395 | end of a page content stream.
|
---|
| 2396 | Accept code-to-CID-type CMaps as ToUnicode CMaps (to work around buggy
|
---|
| 2397 | PDF generators).
|
---|
| 2398 | Unicode-to-unicode maps weren't working correctly with fonts that have
|
---|
| 2399 | an "Identity" encoding.
|
---|
| 2400 | Modify the lexer to interpret "--123.4" as -123.4, "--123" as 0, and
|
---|
| 2401 | "123-45" as "123" to match Adobe's behavior.
|
---|
| 2402 | The text extractor now reverses the order of side-by-side columns for
|
---|
| 2403 | right-to-left scripts.
|
---|
| 2404 | Worked on right-to-left script support in pdftohtml (still not
|
---|
| 2405 | complete).
|
---|
| 2406 | Switched the default display mode to continuous (from single page).
|
---|
| 2407 | Added the "-bom" switch to pdftotext.
|
---|
| 2408 | Share font objects when multiple font tags point to the same object.
|
---|
| 2409 | The transfer function goes before alpha blending in the rasterizer
|
---|
| 2410 | pipeline.
|
---|
| 2411 | Added the "-allinvisible" switch to pdftohtml.
|
---|
| 2412 | Added overprint mode (OPM) support in Level 3 PostScript output.
|
---|
| 2413 | Added support for DeviceN color spaces in Level 3 PostScript output.
|
---|
| 2414 | Added the "-userunit" option to pdftops.
|
---|
| 2415 | Added the "-raw" and "-list" options to pdfimages.
|
---|
| 2416 | Pdfimages now writes PGM files (instead of PPM files) for DeviceGray
|
---|
| 2417 | and CalGray images.
|
---|
| 2418 | Added grayscale PostScript output -- added the '-level2gray' and
|
---|
| 2419 | '-level3gray' switches to pdftops.
|
---|
| 2420 | Fix up Type 1 fonts when embedding in PostScript.
|
---|
| 2421 | Added the "problematic" column to pdffonts output.
|
---|
| 2422 | Generate an appearance stream for signature fields in AcroForms.
|
---|
| 2423 | Correctly handle line dash patterns with zero-length segments when the
|
---|
| 2424 | line cap is butt or project.
|
---|
| 2425 | Added the "strokeAdjust cad" xpdfrc option; fixed some issues with
|
---|
| 2426 | stroke adjustment and projecting line caps.
|
---|
| 2427 | Added support for Code128B bar codes in XFA forms.
|
---|
| 2428 | Look at both the ON and OFF arrays in the default OCCD (optional
|
---|
| 2429 | content config dict), to work around certain broken PDF files.
|
---|
| 2430 | Added support for XFA 'numericEdit' fields.
|
---|
| 2431 | Added support for 'picture' formatting in XFA forms.
|
---|
| 2432 | Added mouseClickN events (in addition to mousePressN and
|
---|
| 2433 | mouseReleaseN).
|
---|
| 2434 | External CID OpenType CFF fonts should map through Unicode (similarly
|
---|
| 2435 | to external CID TrueType fonts).
|
---|
| 2436 | Handle axial and radial shadings in SplashOutputDev, in device space.
|
---|
| 2437 | Use the PDF 2.0 inline image length field.
|
---|
| 2438 | Handle duplicate embedded Type 1 font names in PostScript output.
|
---|
| 2439 | Handle the case of a stroked closed path with a dash pattern -- if the
|
---|
| 2440 | dash pattern is "on" at both the start and end of a subpath, it
|
---|
| 2441 | should be joined.
|
---|
| 2442 | If the line dash phase is negative, add a multiple of 2x the total
|
---|
| 2443 | dash length.
|
---|
| 2444 | Indexed color space indexes should be clipped to [0,hival].
|
---|
| 2445 | Fix the handling of the text render mode with Type 3 fonts, in the
