- 0.2 (95-dec-12)
- ---------------
- First public release.
-
-
- 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.
