|
---|
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()
|

|
---|
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
|
---|
2446 | rasterizer and in PostScript output.
|
---|
2447 | CID font metrics shouldn't be sorted - the PDF 2.0 spec says that, in
|
---|
2448 | the case of duplicate entries, the first entry should be used.
|
---|
2449 | PSOutputDev now converts tiling patterns to PostScript tiling patterns
|
---|
2450 | (in Level 2/3).
|
---|
2451 | Fixed a security hole in SecurityHandler.cc (uninitialized variables).
|
---|
2452 | This vulnerability was discovered by Kushal Shah of Fortinet's
|
---|
2453 | FortiGuard Labs.
|
---|
2454 | Fixed a security hole in Function.cc (write past end of array).
|
---|
2455 | Fixed a security hole with the use of d0/d1 operators outside of a
|
---|
2456 | Type3 CharProc [CVE-2016-9027].
|
---|
