|
|
|
|
0.3 (96-jan-13)
|
|
---------------
|
|
LZW patent workaround.
|
|
Implemented inline images.
|
|
Fixed (mostly) disjoint polygon fills.
|
|
Added remote server stuff.
|
|
Added page number on command line.
|
|
Fixed problem with font encodings which caused character misalignment.
|
|
Fixed inverted CCITT decoding and inverted image mask drawing.
|
|
Now compiles under gcc 2.7.x (ignore those stupid 'unused parameter'
|
|
warnings).
|
|
Many minor bug fixes and optimizations.
|
|
|
|
|
|
0.4 (96-apr-24)
|
|
---------------
|
|
Implemented DCT filter.
|
|
Implemented PostScript output; wrote pdftops program.
|
|
Implemented links.
|
|
Implemented font rotation -- I was wrong: X11R6 servers *do* support
|
|
font rotation (by specifying a matrix in place of a size).
|
|
Added bindings for Home/End, Page Up/Down, arrow keys.
|
|
Added initialZoom resource and -z option.
|
|
Added geometry resource and -g option.
|
|
Fixed image size off-by-one bug.
|
|
Fixed bug where page content is reference to an array of streams.
|
|
Cleaned up uninitialized variables which were causing random problems
|
|
on various platforms.
|
|
Manually skip whitespace before calling atoi() for startxref.
|
|
Replaced calls to XrmCombineFileDatabase() with calls to
|
|
XrmGetFileDatabase() and XrmMergeDatabases() so it will work under
|
|
older versions of X.
|
|
Fixed problem with reading multiple xref tables in updated PDF files.
|
|
Check for encryption and print appropriate error message.
|
|
Rudimentary dithering of images.
|
|
Fixed bug in CCITTFax filter (pass mode followed by horizontal mode).
|
|
Optimized drawImage() and drawImageMask().
|
|
Changed several things to ease porting:
|
|
- changed '__inline' to 'inline' (to adhere to the ANSI standard)
|
|
- surrounded interface/implementation pragmas with #ifdef _GNUC__
|
|
- got rid of empty array initializer lists
|
|
- moved Operator type definition from Gfx.cc to Gfx.h
|
|
- renamed String, uint, etc.
|
|
- ability to uncompress to file (NO_POPEN and USE_GZIP flags)
|
|
- added definitions of XK_Page_Up/Down and XPointer for old versions
|
|
of X
|
|
For VMS port:
|
|
- use correct Xdefaults name for VMS, get rid of ltkGetHomeDir()
|
|
- added '#include <stddef.h>' before all X includes
|
|
- renamed files with multiple periods in their names
|
|
Fixed window resizing infinite oscillation bug.
|
|
Fixed problem with string-type (as opposed to stream-type) indexed
|
|
color space lookup tables (which are used in inline images).
|
|
If an X font is not found, try smaller and then larger sizes (this is
|
|
useful for old or broken X servers which can't scale bitmap fonts).
|
|
Added -rgb (color cube size) option.
|
|
Various minor bug fixes.
|
|
|
|
|
|
0.5 (96-may-23)
|
|
---------------
|
|
Fixed bug in LTKWindow which broke the remote server mode.
|
|
Fixed PostScript output:
|
|
- doesn't seg fault if file is unwritable.
|
|
- incorrect DSC comment - need colon in '%%Page:'.
|
|
- use 'imagemask' command for masks.
|
|
- output filters in the correct order.
|
|
- Stream::isBinary() checks the next-to-bottom, not top, stream.
|
|
- if page width > height, rotate it 90 degrees.
|
|
- if page is larger than paper size, scale it down.
|
|
Set default MediaBox to 8.5" x 11" to deal with non-compliant PDF
|
|
files which don't specify a MediaBox.
|
|
Added DEBUG_MEM stuff in gmem.c and gmempp.cc.
|
|
Fixed memory leaks:
|
|
- LTKWindow didn't delete the LTKBox.
|
|
- LinkAction needs a virtual destructor.
|
|
Use $(RANLIB) variable in goo/Makefile and ltk/Makefile.
|
|
Allocate image data after calling XCreateImage, using
|
|
image->bytes_per_line -- works in 24-bit mode now.
|
|
DCTStream rounds width of rowBuf lines up to the next multiple of
|
|
mcuWidth, so last MCU doesn't run off end of buffer.
|
|
Increase size of block (from 255 to 1024 bytes) read at end of file to
|
|
search for 'startxref'.
|
|
Skip past garbage at start of file, look for '%PDF'.
|
|
Moved more compiler options out of Makefiles into Makefile.config.
|
|
Top-level Makefile uses '$(MAKE)' instead of 'make' for making
|
|
subdirectories.
|
|
Space/PageDown/Next and Backspace/PageUp/Previous now moves to
|
|
next/previous page if already scrolled to bottom/top of current
|
|
page.
|
|
|
|
|
|
0.5a (96-jul-09)
|
|
----------------
|
|
[not a public release]
|
|
For PDF 1.2 (a.k.a. Amber, a.k.a. Acrobat 3) support:
|
|
- look for trailer after first xref instead of at end of file.
|
|
Deal with font subsets by converting character names of the form
|
|
'Cnnnn' to the appropriate character from the standard encoding.
|
|
Extract encoding from embedded Type 1 fonts.
|
|
Kludge to fill one-pixel thick polygons.
|
|
Changed X font encoding to use endash for hyphen (gets rid of too-long
|
|
hyphens).
|
|
Handle Resources key in Pages dictionaries (needed for pstoedit
|
|
output).
|
|
Fix comment handling in Parser (needed for pstoedit output).
|
|
Move Bezier curve conversion from GfxState to XOutputDev; look at
|
|
flatness parameter in GfxState.
|
|
Change all of the path functions in XOutputDev (stroke, fill, clip) to
|
|
use the same path transformation/conversion function.
|
|
Rewrote PostScript output driver as a subclass of OutputDev; removed
|
|
duplicated code (ps_ functions) from Gfx.
|
|
Fixed bug in xref code with small (< 1024 bytes) PDF files.
|
|
Implemented BX/EX operators.
|
|
Added PDFDoc class.
|
|
|
|
|
|
0.6 (96-nov-12)
|
|
---------------
|
|
Add support for PostScript output to stdout (-) and to a command
|
|
(|lpr); added -ps option and psFile resource.
|
|
Decryption is implemented but not included in the distribution due to
|
|
legal restrictions: the decryption algorithm is a trade secret of
|
|
RSA, Inc., and the U.S.A. still has bogus export controls on
|
|
cryptography software.
|
|
Added .xpdfrc config file:
|
|
- Added fontmap parameter: user can map PDF font names to X fonts.
|
|
- Added fontpath parameter: search for Type 1 font if encoding is
|
|
not in PDF file.
|
|
Incremental display: display is updated after every 200 commands.
|
|
Added forward and backward by-10-page buttons.
|
|
Links:
|
|
- Implement links with "Launch" actions that point to PDF files.
|
|
- Draw borders around links.
|
|
- Handle links with named destinations.
|
|
- GoToR links specify a page number instead of a page reference.
|
|
Optimizations:
|
|
- Rewrote Stream to use buffering, and added lookChar() functions;
|
|
rewrote Lexer to take advantage of this.
|
|
- Use hash tables for name->code mapping in font encodings.
|
|
- Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and
|
|
changed the flatness test.
|
|
Added file name to window title.
|
|
Implemented RunLength filter.
|
|
Implemented forms.
|
|
Convert ObjType to an enum.
|
|
Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with
|
|
incorrect PDF files.
|
|
Changed color selection so that very pale colors don't map to white.
|
|
Fixed bug in CCITTFax filter (multiple make-up codes).
|
|
In GString::clear(): need to set length to 0 before calling resize().
|
|
Base initial window size on first displayed page, not page 1; deal
|
|
correctly with rotated pages.
|
|
Added ltkGetIntResource() and LTKApp::getIntResource().
|
|
PostScript output fixes:
|
|
- Escape backslashes in strings.
|
|
- When doing ASCII85 encoding, keep both chars of EOF marker ('~>')
|
|
on same line.
|
|
- Add extra line '%-EOD-' after image data streams; call wrapper
|
|
functions for image and imagemask which look for this line -- this
|
|
should fix the 'too much data in stream' bug.
|
|
- Font tags can be reused for different fonts on different pages --
|
|
so use font object reference (number/generation) instead.
|
|
Initialize character widths to zero (this caused crashes on OSF/1).
|
|
Handle image masks which go outside of pixmap.
|
|
Makefile.config changes:
|
|
- Remove -o in C++ compile rule.
|
|
- Add $(AR) variable.
|
|
Code which read char widths from font dictionary read all but the last
|
|
width.
|
|
Add 'return 0;' to main() in xpdf and pdftops.
|
|
Allow fonts to use StandardEncoding.
|
|
Convert man pages to VMS help files.
|
|
|
|
0.7 (97-may-28)
|
|
---------------
|
|
Implemented FlateDecode filter (for PDF 1.2).
|
|
Basic xref table reconstruction for damaged files
|
|
New pdftotext program converts PDF to plain text.
|
|
Implemented menus in LTK; added a menu to xpdf.
|
|
Added open and save functions; allow xpdf to start without any PDF
|
|
file.
|
|
Implemented text find.
|
|
Implemented text select/copy.
|
|
Change mouse cursor when it's over a link.
|
|
Embed Type 1 fonts in PostScript output.
|
|
Moved rotate functions to menu; added quit to menu.
|
|
Fixed stroke color bug in PostScript output (was using fill color
|
|
instead of stroke color; this sometimes caused lines to be missing
|
|
(white) in PostScript output).
|
|
Support Launch-type links -- pops up a dialog before executing
|
|
anything. Expects the A (action) dictionary to contain a Unix
|
|
dictionary with F (file) and P (paremeter) keys just like the Win
|
|
dictionary.
|
|
A moveto op all by itself should just be discarded, instead of
|
|
generating a subpath with one point (this was causing seg faults).
|
|
Balanced parentheses in strings don't need to be escaped.
|
|
Tj operator in PostScript prolog didn't check for zero when dividing
|
|
by length of string.
|
|
Implemented selection in LTK; TextIn widgets support dragging/copy/
|
|
paste.
|
|
Handle font subsets that use hex character codes.
|
|
Added icon pixmap; added the XPMLIB and NO_XPM variables to
|
|
Makefile.config.
|
|
Fixed subtle bug in use of horizontal scaling parameter (it affects
|
|
only the width of drawn characters, not positioning done in text
|
|
space).
|
|
Memory testing (with DEBUG_MEM):
|
|
- gmalloc now fills memory blocks with garbage to catch unitialized
|
|
fields.
|
|
- gfree fills memory blocks with garbage to catch uses of freed
|
|
blocks.
|
|
Handle image masks which go off the pixmap on the top and/or left.
|
|
Fixed inline functions which had two return statements (to make the
|
|
HP, SCO, and other cfront-based compilers happy).
|
|
Fixed bug which caused seg faults when following a link to a different
|
|
file (info in LinkGoto object was used after link was deleted by
|
|
loadFile).
|
|
If page content is an array of streams, the streams are concatenated;
|
|
objects and commands can span multiple streams.
|
|
If file open fails, try lower-casing and upper-casing the file name.
|
|
Commands should end when lexer sees a '/' character.
|
|
GString::append(char *, int) was broken.
|
|
Changed LTKScrollingCanvas redraw to be more efficient: copy as much
|
|
as possible from window before copying from off-screen pixmap.
|
|
Ignore gs (set extended graphics state) operator.
|
|
Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the
|
|
weird colorspaces are not yet implemented).
|
|
Named destinations (for links) can be strings as well as names; deal
|
|
with the names tree in the catalog.
|
|
Clip to the page CropBox.
|
|
Added '-q' to gzip options (to suppress warnings, in case user has -v
|
|
in GZIP env var).
|
|
Added 'include Makefile.config' to top-level Makefile.
|
|
Added INSTALL variable to Makefile.config; used in top-level
|
|
Makefile.
|
|
Always initialize LinkDest left/bottom/top/right/zoom fields (bogus
|
|
floating point values were causing crashes on Alpha).
|
|
Added Makefile.config options for Digital Unix (DEC compilers), HP-UX
|
|
(HP compilers), SCO Unix, and Evans & Sutherland ES/OS.
|
|
Added flag to set stream mode in fopen call for VMS.
|
|
Rewrote Link module.
|
|
Pages with no contents shouldn't cause an error message.
|
|
In PostScript output: pdfImM needs to set fill color before doing
|
|
imagemask.
|
|
If font doesn't specify character widths, use widths from built-in
|
|
font, based on font flags.
|
|
Fixed LTK scrollbar to delay before repeating and to control the
|
|
period between repeats.
|
|
Removed window/widget copy() methods (they were untested and unused).
|
|
Unknown filter types produce a single error message instead of a
|
|
stream of errors.
|
|
Added a dummy target in top-level Makefile so making individual
|
|
executables (e.g., 'make pdftops') should now work.
|
|
Added optional xpdf-flip.ltk with buttons on right side instead of
|
|
bottom of window.
|
|
|
|
0.7a (98-feb-22)
|
|
----------------
|
|
Moved find command from menu to toolbar button ('f' key still works).
|
|
Support TrueColor visuals.
|
|
Added a -cmap option and a installCmap resource to install a private
|
|
colormap.
|
|
Mouse button 2 pans the window.
|
|
Selecting a URI link now executes a configurable command (from the
|
|
urlCommand resource).
|
|
Added a "link info" display which shows the URL or file for the link
|
|
under the mouse.
|
|
Don't draw (or convert to PostScript) text drawn in render modes 3 and
|
|
7 -- this is invisible text, used by Acrobat Capture; this text is
|
|
still passed to the TextPage object so that selection works.
|
|
Recognize (and quietly ignore) marked content operators (BMC, BDC,
|
|
EMC, MP, DP).
|
|
Recognize new color-setting operators (scn, SCN).
|
|
Added A4_PAPER option.
|
|
Embed external Type 1 font files (this currently only works with PFA
|
|
files).
|
|
Added "-level1" option (in xpdf and pdftops) to generate Level 1
|
|
PostScript.
|
|
Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT
|
|
flag, and use configure to autodetect (for HP-UX).
|
|
Fixed appendToPath() to behave reasonably when appending ".." to root
|
|
directory.
|
|
Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf
|
|
to crash under OSF/1).
|
|
ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and
|
|
could run past the end of the stream in damaged files.
|
|
Handle hex escapes (#xx) in names. Still allow the name /# for
|
|
backward-compatibility.
|
|
Check for NULL characters in encoding array in GfxFont.cc (was calling
|
|
strcmp() with NULL which crashed under Solaris).
|
|
PageAttrs::PageAttrs() didn't initialize crop box boundaries.
|
|
Changed uses of lookup() to lookupNF() in XRef.cc.
|
|
Fixed type checking of operators which take a variable number of
|
|
args.
|
|
Gfx::buildImageStream() doesn't need to check for parser (since I got
|
|
rid of the bogus array-of-command thing).
|
|
XOutputFont matches on font reference instead of font tag (similar to
|
|
PSOutputDev fix).
|
|
Fixed bug in position calculation for multi-char substitutions in
|
|
XOutputDev.
|
|
Cleaned up local variables which hid class variables.
|
|
Optimized variable length decoding in CCITTFaxStream.
|
|
Set link border width to zero if Border dictionary entry is missing.
|
|
Throw away zero-length strings in TextOutputDev -- they don't have
|
|
valid xMin/xMax values.
|
|
Swapped order of XLIBS and XPMLIB in xpdf/Makefile.
|
|
Deleted 'LTKApp::' in function declaration in LTKApp.h.
|
|
Changed '(XKeyEvent *)&event' to '&event.xkey' in LTKApp.cc.
|
|
Check that the link rectangle coordinates are in the correct order,
|
|
and swap if necessary.
|
|
TextOutputDev didn't set text to NULL, which caused pdftotext to
|
|
segfault if it couldn't open it's output file.
|
|
Fixed a hash table search bug in GfxFontEncoding::getCharCode().
|
|
Cleaned up colorspace code: rewrote GfxColorSpace and added
|
|
GfxImageColorMap; cleaned up PSOutputDev::doImage.
|
|
Handle named colorspaces in images.
|
|
Correctly set the default color after a colorspace change.
|
|
Old setcolor operators now set the colorspace.
|
|
Fixed bug with uncompressed blocks in FlateStream.
|
|
Fixed bug with fixed Huffman code table in FlateStream.
|
|
Added hash table of X windows (for LTKWindow and LTKWidget) to LTKApp
|
|
and replaced calls to XQueryTree with hash table searches -- this
|
|
avoids a roundtrip to the server for each event and also fixes the
|
|
problem where XQueryTree crashed if the window no longer existed
|
|
(with leftover events from a destroyed window). (Thanks to Yair
|
|
Lenga for the suggestion.)
|
|
Create a new GC for selection -- xor black and white (instead of LTK
|
|
foreground and background).
|
|
Fixed crash with blank lines in .xpdfrc.
|
|
Allow spaces in font descriptors in fontmap lines in .xpdfrc.
|
|
Check for bogus object number in XRef::fetch().
|
|
Use MacRomanEncoding for TrueType fonts that don't specify an
|
|
encoding.
|
|
Certain PDF generators apparently don't include FontDescriptors for
|
|
Arial, TimesNewRoman, and CourierNew -- set GfxFont flags
|
|
appropriately.
|
|
Fixed a bug in width guessing in GfxFont -- sans serif and serif were
|
|
swapped.
|
|
Rewrote XRef::readXRef() to avoid using a parser to read the xref
|
|
entries.
|
|
Added NO_TEXT_SELECT option.
|
|
Ignore APPn/COM/etc. markers in DCT streams.
|
|
Replaced select() with XMultiplexInput() in LTKApp.cc for VMS.
|
|
Handle WM_DELETE_WINDOW protocol -- if you ask the window manager to
|
|
delete the xpdf window, xpdf will exit cleanly; other
|
|
windows/dialogs are simply closed.
|
|
Optimized DCT decoder; switched to integer arithmetic.
|
|
The "/Type /Annots" field in an annotation dictionary is optional.
|
|
Check for null nameTree in Catalog::findDest().
|
|
In XOutputDev, search user font map before default font map.
|
|
Added "normal" SETWIDTH parameter to all font descriptors in
|
|
XOutputDev (some systems have a narrow-width Helvetica font).
|
|
Added FOPEN_READ_BIN and FOPEN_WRITE_BIN to support Win32.
|
|
Added a hack which allows better font substitution for some Type 3
|
|
fonts. Also allow character names of the form /nn and /nnn.
|
|
Added <strings.h> and <bstring.h> to LTKApp.cc (needed by AIX and IRIX
|
|
for bzero() declaration for FD_ZERO).
|
|
|
|
0.80 (98-nov-27)
|
|
----------------
|
|
Support for some Japanese fonts (Type 0 fonts using the Adobe-Japan1-2
|
|
character collection, horizontal only).
|
|
Added pdfinfo application.
|
|
Added pdftopbm application.
|
|
Added pdfimages application.
|
|
Added -papercolor option and .paperColor resource.
|
|
Fixed divide-by-zero problem in XOutputDev Type 3 font matrix kludge.
|
|
Font subset char names can be 'Bxx' as well as 'Cxx' and 'Gxx'.
|
|
Fixed bug in color space conversion in DCTStream filter (YCC->RGB was
|
|
correct, YCCK->CMYK was broken).
|
|
Added XRef::getDocInfo() and PDFDoc::getDocInfo() to support pdfinfo.
|
|
Optimized GfxImageColorMap.
|
|
Lexer::getStream(), getPos(), and setPos() check for null stream.
|
|
Decryption code now does strings as well as streams.
|
|
ASCII85 decoder rounds short tuples up instead of down.
|
|
CropBox and MediaBox can be non-integers.
|
|
PostScript output:
|
|
- Use a rectangle operator.
|
|
- Call setpagedevice with page size.
|
|
- Insert %%PageOrientation comments.
|
|
- Add paper size flags (-paperw and -paperh) to xpdf and pdftops.
|
|
- If HAVE_POPEN is not defined, and user tries to print to '|...',
|
|
the PSOutputDev destructor tried to write to the PS file.
|
|
- Added support for forms (pdftops -form).
|
|
Removed error messages for empty paths in stroke, fill, etc. operators.
|
|
Don't allow flatnesses less than 1 in XOutputDev (this speeds up
|
|
rendering a little bit when there are lots of tiny curves).
|
|
Moved the font subset character name guessing from GfxFont to
|
|
XOutputDev and TextOutputDev - now these files print correctly.
|
|
Cast argument to XFree() to XPointer; add XPointer definition where
|
|
necessary (portability fixes).
|
|
Various minor VMS fixes.
|
|
Changes to configure script and Makefiles:
|
|
- Print a warning if X is missing.
|
|
- Use C++ when checking select() argument type (HP-UX).
|
|
- Use 0 instead of NULL when checking select().
|
|
- Default to gcc instead of c++.
|
|
- Get rid of AC_C_INLINE -- this is meant for C, not C++.
|
|
- Changed -USE_GZIP to -DUSE_GZIP.
|
|
- Added ability to compile ouside of the source tree.
|
|
- Added .cc.o rule to {goo,ltk,xpdf}/Makefile.in.
|
|
- Added @LIBS@ to XLIBS in xpdf/Makefile.in.
|
|
- In top-level Makefile.in: added '-' to clean commands; added
|
|
distclean rule.
|
|
- Create install directories.
|
|
- Use INSTALL_DATA (instead of INSTALL) for man pages.
|
|
- Changed xpdf-ltk.h rule to avoid leaving an empty file when
|
|
ltkbuild fails.
|
|
- Change things so that by default, ltkbuild is not built and
|
|
xpdf-ltk.h is not rebuilt.
|
|
- Use AM_PROG_CC_STDC to add compiler flags for ANSI C.
|
|
- Modify autoconf's builtin macros to check for xlC.
|
|
- Use Steve Robbins' smr_CHECK_LIB to test for pixmap library (Xpm)
|
|
-- this should fix the problems on systems that have the library
|
|
but not the include file.
|
|
- Added better test for sys/select.h, sys/bsdtypes.h, strings.h,
|
|
bstring.h.
|
|
- New VMS make scripts from Martin P.J. Zinser.
|
|
- Moved dependences into Makefile.in -- this gets rid of problems
|
|
with 'cc -MM' (which is gcc-specific) and 'include Makefile.dep'
|
|
(which isn't supported by all make implementations). Also changed
|
|
all non-system include files to '#include "..."' (from '<...>').
|
|
Tweaked the TextOutputDev heuristics slightly.
|
|
Modify Gfx to use a stack of resources -- this is necessary for Form
|
|
XObjects, which can define their own local resources; also modified
|
|
PSOutputDev to dump fonts used by forms.

|
|
Fixed a bug with form bounding boxes.

Modified the t1lib support -- replace libt1x code with my own code.
|
|
Type 1 and TrueType fonts are now handled similarly, and clipping
|
|
works on Type 1 fonts.
|
|
Don't print copyright banner (xpdf); add -v switch to get copyright
|
|
and version info (all apps); get rid of -err switch (xpdf).

|
|
modification time is different.
|
|
Fixed a memory (malloc size) bug in CCITTFaxStream.
|
|
Fixed two bugs in FontEncoding::hash() -- handle zero-length character

character names with high-bit-set characters (use unsigned ints).
|
|
Added PDFDoc::isLinearized() and corresponding code in pdfinfo.cc.
|
|
Handle files with an incorrect page count in the Pages dictionary
|
|
(FOP, from the Apache project produces a page count of 0).
|
|
Handle TrueType equivalents to the Base14 fonts (Arial, TimesNewRoman,

|
CourierNew) -- Adobe's tools use these names without embedding the
|
|
fonts.
|
|
Tweaked the Type 3 font sizing kludge.
|
|
Changed pdfimages (ImageOutputDev) so it doesn't output JPEG files for
|
|
4-component color spaces, since these seem to confuse most image
|
|
viewers.
|
|
Added support for generating OPI comments (pdftops -opi).
|
|
In XOutputDev::drawImage() and drawImageMask(), check for images that
|
|

|
|
Changed enough occurrences of 'char *' to 'const char *' to keep gcc
|
|
2.95 from barfing.
|
|
Support for Latin-2 and Latin-5 in pdftotext (however, this will only
|
|
work if the PDF file contains correct font encodings, which seems to
|
|
be rare).
|
|
TextOutputDev converts "eightoldstyle" to "eight", etc.
|
|
Don't use the return value from sprintf() -- most systems return the
|
|
length, but some return the string.
|
|
Minor fixes for SunOS 4.
|
|
Configure script looks for both select() and fd_set in sys/select.h.
|
|
Configure script checks for gethostbyname() in -lbsd (for LynxOS).

|
|
|
|

|
|
only).
|
|
Implemented Stamp annotations.
|
|
Implemented Named link actions.
|
|
Fixed a really dumb bug in the TrueColor code in SFont (which affects
|
|
both Type 1 and TrueType font rendering on 16-bit displays).
|
|
Rewrote the GfxColorSpace / GfxColor code.
|
|
Switched from djgppcfg to dj_make.bat (from Michael Richmond).
|
|
Bug in the Type 1 encoding parser -- couldn't handle lines of the form
|
|
'dup NNN/name put' (with no space between the code and the name).
|
|
Fixed the mkstemp() test in configure.in -- switched from
|
|
AC_TRY_COMPILE to AC_TRY_LINK and added <unistd.h>.
|
|
Added DESTDIR to top-level Makefile.in.
|
|
Fixed an incorrect OPI comment in PSOutputDev.
|

Minor tweak to the CCITTFax code to avoid writing past the end of an
|
|
array on an invalid data stream.

Xpdf crashed if the user selected 'reload' when no document was
|
|
loaded.
|
|
Look for character names of the form "xx" (two hex digits with no
|
|
leading alphabetic char) and 'cNNN' (decimal digits with a leading
|
|
alphabetic char that happens to be a hex digit).
|
|
FlateStream didn't correctly handle zero-length streams.
|
|
Xref reconstruction didn't handle the case where the opening "<<"
|
|
immediately followed "trailer" with no intervening whitespace.
|
|
Fix the %%DocumentSuppliedResources comment in EPS output.
|
|
Scale annotations to fit their rectangles.
|
|
Added Stream::close() to handle cases (e.g., patterns) where a Stream
|
|
object is used multiple times before it is deleted.
|
|
Added the topLevel arg to Gfx::go() so it doesn't call out->dump() for
|
|
every pattern element (and form).
|
|
Rearranged the GfxResources class.
|
|
Clean up white space handling in Lexer.
|
|
Make the dpi parameter to PDFDoc::displayPage etc. a double - this
|
|
avoids margin gaps with fit-page and fit-width.
|
|
Fix a rounding problem in xpdf.cc that was causing the window to
|
|
sometimes be one pixel too small.
|
|
Fixed a minor bug in dealing with Base-14 TrueType font names.

|
|
|
|
0.91c (2000-nov-19)
|
|
-------------------
|
|
Fix an endianness problem in the Type 1 font code which resulted in an
|
|
incorrect display with "-t1lib plain" on big-endian systems.
|
|
CCITTFax stream decoder will skip over extra zero bits at end of line,
|
|
even if EncodedByteAlign flag wasn't set.
|
|
Added Big5 support to pdftotext (with CHINESE_CNS_SUPPORT enabled).
|
|
Fixed a typo in the CNS/Big5 encoding translation table.
|
|
Change the form code in PSOutputDev to store images in arrays of
|
|
strings.
|
|
The xref reconstruction (for damaged files) now also looks for
|
|
'endstream' tags, and the parser uses this information when setting
|
|
up stream objects.
|
|
In pdfinfo, convert Unicode chars in the 00xx range into 8-bit chars;
|
|
print a warning if there are any other Unicode chars.
|
|
|
|
0.92 (2000-dec-03)
|
|

|
|
title.
|
|
Check for <freetype.h> in addition to <freetype/freetype.h>.
|

bug where configure wasn't correctly finding t1lib.
|
|
|
|
0.92a (2000-dec-17)
|
|
-------------------

|
|
-------------------
|
|
Fixed a bug in the new image transformation code.
|
|
Look for character names of the form "<letter><digit><digit>", instead
|
|
of looking for names beginning with a few specific letters.
|
|
T1FontFile::T1FontFile wasn't initializing vars, and ~T1FontFile
|
|
wasn't checking before calling T1_DeleteFont -- this caused crashes
|
|
if it tried to open a nonexistent font file.
|
|
Catalog::Catalog didn't set baseURI to NULL early enough.
|
|
Tweak the check for strings.h in the configure script.
|
|
Yet another fix for the image rotation code in XOutputDev --
|
|
off-by-one problem when upsampling.

|
|
Allow FreeType2 to render user-supplied Type 1 base fonts.
|
|
Opening a new file from full-screen mode tried to scroll.
|
|
Fixed a bug in GfxFont constructor (missing check for NULL base font
|
|
name).
|
|
Don't crash if a Type 1 font's FontBBox is non-integer.
|

|
|
instead of the top-left pixel.
|
|
Automatically activate the text input widget in the find window.
|
|
Changed a Japanese char code mapping in XOutputDev and TextOutputDev:
|

|
|
character).
|
|
Add the 0/+/-/z/w key bindings to control the zoom setting.
|
|
Fixed ImageOutputDev (pdfimages) to correctly handle inline image
|
|
masks.
|
|
Extract ascent/descent info from font descriptor.
|
|
|
|

Added the "-htmlmeta" option to pdftotext.
|
|
In TextOutputDev, when computing the number of blank lines to insert,
|
|
do a sanity check on the result.
|
|
If both FlateDecode and some other filter (e.g., DCTDecode) were
|
|
applied to an image stream, getPSFilter() crashed instead of just
|
|
returning NULL.
|
|
Handle the /Identity function.
|
|
|
|
0.92e (2001-aug-23)
|
|
-------------------
|
|
Widths in font dict should override built-in font widths.
|
|
Changed "rotate left/right" menu items to "rotate
|
|
clockwise/counterclockwise".
|
|
The link parsing code choked if the Border array was incorrect (too
|
|
short).
|
|
Modified PSOutputDev to output CMYK for fill/stroke colors.
|
|
|
|
0.93 (2001-oct-25)
|
|
------------------
|

|
|
doesn't exist.
|
|
Accept and verify owner password; if correct, allow all actions.
|
|
Added a "-level2sep" option to pdftops to generate Level 2 separable
|
|
PostScript. The PostScript separation convention operators are used
|
|
to handle custom (spot) colors. [Thanks to Thomas Freitag for help
|
|
on this.]
|
|
Add support for FreeType 2 to the configure script. Warning: this
|
|
requires FT 2.0.5 or newer.
|
|
Fixed the bounding rectangle overlap test in the disconnected subpath
|
|
fill hack in XOutputDev.
|
|
Stupid typo in font name table in PSOutputDev.
|
|
Changing the zoom setting with a keyboard shortcut didn't update the
|
|
displayed setting.
|
|
Modified the mouse wheel support and added the second wheel (mouse
|
|
buttons 6 and 7). [Thanks to Michal Pasternak.]
|
|
Character and word spacing is affected by horizontal scaling (display
|
|
and PS output). [Thanks to Eddy Ng.]
|
|
Rotation specified by the text matrix, character spacing, and
|
|
horizontal scaling interacted incorrectly (display and PS output).
|
|
Some broken Type 1/1C fonts have a zero BBox -- kludge around this by
|
|
assuming a largeish BBox.
|
|
Handle PDF files with an incorrect (too small) xref table size.
|
|
Allow "-?" and "--help" as aliases for "-h" (all apps).
|
|
Correctly handle unescaped parens in strings in Lexer.
|

Removed a comma inside a string in configure.in.
|
|
Kludge around broken PDF files that use char 32 but encode it as
|
|
.notdef instead of space.
|
|
Clean up various compiler warnings: use constructor args like "fooA"
|
|
if there is a field named "foo". Everything now compiles cleanly
|
|
under gcc 2.91.66, 2.95.2, and 3.0.1.
|
|
Page objects now read all of the page rectangles (MediaBox, CropBox,
|
|
BleedBox, TrimBox, ArtBox), as requested by the pdfTeX folks.
|
|
Added a new PDFRectangle struct to hold these.
|
|
Use XOutputDev's Type 3 font size hack in TextOutputDev too, so it
|
|
does a little better job of extracting text in Type 3 fonts.
|
|

|
|
Work around a bug in cygwin's implementation of fseek.

|
Minor fixes for OS/2.
|
|
Fix the system config file path for VMS.
|
|
Fix an uninitialized var in XOutputDev that caused crashes on Alphas.
|
|
Don't incrementally update the display in full-screen mode.
|
|
For Type 1/1C fonts, use the FontBBox from the PDF FontDescriptor
|
|
(instead of the one in the font file) if present -- this avoids
|
|
problems with fonts that have non-standard FontMatrixes.
|
|
Add the Euro character to WinAnsiEncoding.
|
|
Track the bounding box of the clip region to make rendering patterns
|
|
more efficient.
|

|
|
- everything is Unicode-based
|
|
- 16-bit fonts are handled much more cleanly
|
|
- text output encoding can be set more flexibly
|
|
New .xpdfrc config files.
|
|
|
|
1.00 (2002-feb-01)
|
|
------------------
|
|
More work on the font encoding rewrite:
|
|
- use the ToUnicode font dict entry
|
|
- pdfinfo and pdftotext (with '-htmlmeta') convert info strings to
|
|
the selected text encoding
|
|
Added key bindings for forward ('v') and backward ('b').
|
|
Added the pdffonts program which lists the fonts used in a PDF file.
|
|
Fixed several problems in the TrueType font embedding code (for
|
|
PostScript output).
|
|
Accept named destination on command line.
|
|
Added several new items to pdfinfo: file size, PDF version, tagged
|
|
(yes or no), XML metadata (with the -meta option).
|
|
Pdftops didn't get the portrait/landscape setting correct for PDF
|
|
files with rotated pages.
|
|
The TrueTypeFontFile class (including the Type 42 converter) now
|
|
understands cmap format 6.
|
|
Improved the "about" window -- mention the GPL, add a list of key
|
|
bindings.
|
|
Added Zcaron and zcaron characters to WinAnsiEncoding.
|
|
The '0' keyboard shortcut didn't update the zoom popup menu.
|
|
Handle the complete list of alternate names for the Base14 fonts.
|
|
Fixed substitute font scaling in XOutputDev - scale only the width,
|
|
not the height.
|
|
Implemented stitching (type 3) functions.
|
|
Handle the case of moveto/closepath/clip, which defines an empty
|
|
clipping region.
|
|
Move dependences into separate Makefile.dep files; get rid of the
|
|
distdepend target.
|
|
Move all of the configure-script-generated -D options out of the
|
|
Makefiles and into a top-level .h file (aconf.h).
|
|
Cleaned up the FreeType 1/2 detection code in the configure script.
|
|
Pdfinfo prints dates in a more readable format.
|
|
Fixed a bug in the Paeth image predictor.
|
|
Handle annotations with multiple states.
|
|
Another workaround for buggy X servers: clip points that are way out
|
|
of bounds.
|
|
Added libpaper support (for Debian).
|
|
Generate PostScript DSC resource comments for PS (not just EPS)
|
|
files.
|
|
The save and restore (q/Q) operators shouldn't save/restore the path.
|
|
Performance optimization: disable pattern drawing in TextOutputDev.
|
|
|
|
1.00a (2002-feb-25)
|
|
-------------------
|
|
Added an optimized special case for one-bit images in XOutputDev.
|
|
Implemented CID TrueType font embedding; added a psEmbedCIDTrueType
|
|
option.
|
|
The initialZoom X resource was broken.
|
|
The reverse MacRoman encoding should return 32 for "space" (not 202,
|
|
which is an alternate encoding).
|
|
Tweaks to the FreeType 2 support: only disable hinting if the bytecode
|
|
interpreter is disabled (i.e., disable autohinting but not bytecode
|
|
hinting); add some padding to the glyph cache for CJK fonts.
|
|
Added level3 and level3Sep options for the psLevel setting and
|
|
corresponding -level3 and -level3Sep options to pdftops.
|
|
Added a -level2 option to pdftops for consistency.
|
|
Avoid a divide by zero in pdftotext. [Thanks to William Bader.]
|
|
Added a Greek language support package. [Thanks to Alexandros
|
|
Diamantidis and Maria Adaloglou.]
|
|
Don't bother trying to extract a "builtin" encoding from a TrueType
|
|
font.
|
|
Accept either a page number or a page reference in a link
|
|
destination.
|
|
Update the fontFixedWidth flag in GfxFont after reading the char
|
|
widths (used by the Acorn RiscOS port).
|
|
Removed yet another (illegal but not caught by gcc) class specified
|
|
from a .h file.
|
|
Avoid using snprintf - it's not available everywhere.
|
|
Improved the CMYK->RGB transform.
|
|
Use mkstemps where available.
|
|
|
|
1.01 (2002-may-20)
|
|
------------------
|
|
Implemented Type 3 fonts.
|
|
Implemented PostScript CID font embedding; added a
|
|
psEmbedCIDPostScriptFonts option.
|
|
Implemented PostScript 16-bit font substitution; added psNamedFont16
|
|
and psFont16 options.
|
|
Moved the initialZoom setting from X resources to the xpdfrc file.
|
|
Implemented the radial shading type in the sh (shaded fill) operator.
|
|
[Thanks to Mike Sweet.]
|
|
Added an 'include' command to the xpdfrc format.
|
|
Added the displayNamedCIDFontX option so different fonts can be used
|
|
within one character collection.
|
|
Added a simple reverse video mode (-rv switch, xpdf.reverseVideo
|
|
resource).
|
|
Implemented stroked text in XOutputDev (with t1lib and FreeType2).
|
|
[Thanks to Leonard Rosenthol.]
|
|
Implemented stroked text in PSOutputDev.
|
|
Added a built-in Unicode map for UCS-2.
|
|
New key binding in xpdf: 'g' activates the page number text field.
|
|
PSOutputDev will now embed external TrueType fonts in addition to
|
|
external Type 1 fonts.
|
|
The psEmbedType1Fonts and psEmbedTrueTypeFonts options were missing
|
|
the "Fonts" suffix.
|
|
Documentation in xpdf.1 for -freetype option was wrong.
|
|
Added the Big5ascii Unicode map to the Chinese-traditional support
|
|
package (maps 7-bit ASCII straight through). [Thanks to Lawrence
|
|
Lai.]
|
|
Modified the EUC-CN and EUC-JP encodings to pass 7-bit ASCII straight
|
|
through. [Thanks to Lawrence Lai.]
|
|
Avoid a divide by zero in XOutputDev. [Thanks to Simon Burge.]
|
|
Remove old code in openTempFile that removed an extension from the
|
|
name returned by tmpnam.
|
|
Tweak the scrolling behavior when switching pages. [Thanks to Case
|
|
Jones.]
|
|
In the code that guesses character names (for font subsets), also
|
|
handle names of the form 'ABnnn'. [Thanks to Colin Granville.]
|
|
Fix the transform code for annotations.
|
|
Improved the CMap file parser to handle more general PostScript
|
|
lexical conventions.
|
|
Added '-enc' option to pdfinfo.
|
|
Added the small caps and oldstyle numbers from Adobe's Unicode
|
|
corporate use area to the Latin1 and ASCII7 Unicode maps.
|
|
The code in TextOutputDev that guesses Type 3 font size could generate
|
|
a zero size, which resulted in div-by-zero errors.
|
|
Various tools (including Adobe's) occasionally embed Type 1 fonts but
|
|
label them Type 1C - so check for a '%!' at the start.
|
|
Some tools embed Type 1C fonts with an extra whitespace char at the
|
|
beginning - just skip over it.
|
|
Fixed a typo in the Simplified Chinese add-to-xpdfrc file.
|
|
Updates to dj_make.bat and the djgpp build instructions.
|
|
Added a Turkish language support package.
|
|
Updated VMS build scripts. [Thanks to Martin Zinser.]
|
|
Modify the incremental display update code to redraw less often if
|
|
most of the commands are vector graphics, as opposed to text and
|
|
images.
|
|
Tweak the Type 1 font bbox code to look at the bboxes in both the PDF
|
|
font object and the embedded font file.
|
|
Fixed the ETenms-B5-H CMap file (for traditional Chinese) to map the
|
|
Latin characters to their proportional versions.
|
|
Added an optional displayCIDFontX entry for one of the Arphic TrueType
|
|
fonts in the traditional Chinese 'add-to-xpdfrc' file.
|
|
Remove leading '-' on include statements in Makefiles.
|
|
Added psASCIIHex parameter.
|
|
Added the GBK Unicode map to the simplified Chinese language pack.
|
|
Pdftotext now opens the text file in binary mode to avoid Microsoft's
|
|
annoying automatic end-of-line translation stuff.
|
|
Added an executeCommand function in goo/gfile.cc. [Thanks to Mikhail
|
|
Kruk.]
|
|
The %ALDImagePosition OPI comment was wrong if the page was scaled to
|
|
a different paper size.
|
|
The OPI code was saving the default transform matrix before calling
|
|
setpagedevice, which can change the matrix.
|
|
Fixed a crash when an inline image dictionary contains garbage.
|
|
Upgraded to autoconf 2.53.
|
|
Use unsigned int file offsets, to allow access to PDF files in the 2-4
|
|
GB size range; use fseek64/ftell64 if available.
|
|
Fixed two floating point exception cases that came up with broken PDF
|
|
files.
|
|
Avoid a crash when printing an error message regarding an unnamed
|
|
font.
|
|
Default link border width should be 1. [Thanks to Michael Pfeiffer.]
|
|
Minor tweak to build with FreeType 2.1.0.
|
|
Handle "weird" characters in PostScript font names.
|
|
PSOutputDev now handles PostScript XObjects.
|
|
Added several more page attributes for the pdftex project.
|
|
Transferred the copyright to Glyph & Cog, LLC.
|
|
|
|
2.00 (2002-nov-04)

|
|
Added key binding for '?' to bring up the about/help dialog.
|
|
In TextOutputDev, ignore any text that's outside the page bounding
|
|
box.
|
|
Text extraction throws away "tiny" characters after the first 20000
|
|
per page, to avoid really slow runtimes with PDF files that use
|
|
special fonts to do shading or cross-hatching; added the
|
|
'textKeepTinyChars' option to disable this behavior.
|
|
Text extraction discards duplicated text (fake boldface, shadow
|
|
effects).
|
|
Added ctrl-F as a key binding for find.
|
|
Added a "find next" function, bound to ctrl-G.
|
|
Added ctrl-P as a key binding for print.
|

Modified the DCT decoder to handle progressive and non-interleaved
|
|
JPEG streams.

|
|
as an X resource.

|
|
DeviceN base color spaces.
|
|
Added lowercase Roman numerals to ISO-2022-CN.unicodeMap (simplified
|
|
Chinese support package).
|
|
Tweak the image scaling code to better handle flipped (top-bottom
|
|
and/or left-right) images.
|
|
Generate correct PostScript code for inline images and images in Type
|
|
3 fonts which are too large for a single PS string.
|
|
Correctly handle indexed color spaces whose base color spaces have
|
|
component ranges other than [0,1].
|
|
Optimized the DCT decoder.
|
|
Fixed mistakes in the list of key bindings in the about/help dialog.
|
|
Optimized the Flate decoder.
|
|
Add literal names for punctuation and digits to the Unicode name
|
|
table.
|
|
Cygwin's popen wants mode "r", not "rb".
|
|
Fixed a bug in the Type 4 function parser (the "if" operator wasn't
|
|
parsed correctly).
|
|
Fix a bug in PS output for TrueType fonts with no PDF encoding.
|
|
Make the bbox size in FTFont more liberal (to avoid problems with
|
|
fonts that have incorrect bboxes).
|
|
Reverse the colors in PBM files generated by pdfimages, so the common
|
|
case (an image mask filled with black) comes out correct.
|
|
Add fseeko/ftello support which is basically identical to
|
|
fseek64/ftell64. [Thanks to Nassib Nassar.]
|
|
Modified column assignment in text extractor to account for characters
|
|
that convert to multiple characters in the output encoding.
|
|
Fix TrueType fonts which have an incorrect cmap table length.
|
|
Work around a pragma bug in the version of gcc that ships with MacOS X
|
|
10.2. [Thanks to Frank Siegert and Andrew Stone.]
|
|
Fix a problem that was causing an infinite loop when a damaged content
|
|
stream contains an 'ID' command inside a dictionary.
|
|
Handle the case where systempapername() returns NULL (libpaper
|
|
support).
|
|
Handle fonts which are defined directly in the font resource
|
|
dictionary rather than as separate objects.
|
|
Track process colors in Level 1 separable PostScript.
|
|
Pdfinfo now checks the return value from mktime to avoid seg faults in
|
|
flakey strftime implementations.
|
|
If duplex is not enabled in PostScript output, leave the duplex
|
|
setting alone, allowing the spooler to insert its own setting.
|
|
Added three missing fclose calls.
|
|
Change the default encoding for TrueType fonts (used when the PDF file
|
|
doesn't specify an encoding) from MacRomanEncoding to
|
|
WinAnsiEncoding.
|
|
Move X_CFLAGS to the end of the list in CXXFLAGS (in Makefile.in) to
|
|
avoid some of the FreeType2 include path problems.

Fixed an obscure bug in the LZW decoder. [Thanks to Martin
|
|
Schroeder.]
|
|
Fixed a bug in decryption when using the newer (PDF 1.4) algorithm
|
|
with shorter-than-128-bit keys.
|
|
Minor optimization for image data streams: the ImageStream class can
|
|
return an entire buffered line.
