TTF2PT1 - CHANGES history

3.3.2 -- November 20, 2000

• Added generation of man pages.
• Added "make install" and "make uninstall".
• Added language option "-l plane".
• In other/showg added better support of comparison files:
  • printing of the comparison file legend;
  • guessing of missing glyph names in a comparison file by code;
  • bounding boxes of all comparison files are used for page layout.
• Added ability to use external t1asm instead of compiling it in.
• Renamed the fonts installation guide from INSTALL*html to FONTS*html to avoid confusion with installation of ttf2pt1 itself.

• Removed erroneous extra fclose(pfa_file).
• Fixed random memory corruption that manifested with crash on Linux when converting fonts not containing glyph names.
• Removed from the output file the comments that confused dvips. Changed other/showg to work without them.
• In other/showg added better checks for missing glyphs, now it gives warnings about them and the output file does not crash PostScript.

• ttf2pfa is no longer included, people interested in history should look for it in the older versions.

3.3.1 -- October 22, 2000

New features:

• Added front-end parser based on the FreeType-2 library. See Makefile for build instructions.
• Changed the handling of encodings to accomodate the FreeType model.
• Further cleaned up the front-end parser interface.

• Fixed a bug that caused core dump on Alpha machines.
• Fixed a bug in the outline smoothing that occasionally caused core dump.
• Cleaned up warnings from picky compilers
• Fixed more bugs in the Windows port (by Stefan Bauer).
• Fixed the RPM spec file (suggested by Brian Armstrong).

3.3.0 -- September 22, 2000

New features:

• Converted most of the outlines' processing to floating point arithmetic.
• Added splitting of curves crossing the quadrant boundaries (no gross damage is done any more to the Marvosym font and others like it).
• Added modular interface for front-end font parsers and option to control their selection at run time.
• Grouped the outline processing control options into one to reduce the options namespace pollution.
• Thomas moved the Chinese maps into a separate module, chinese-maps.
• Thomas added option -V to print version number. In addition, the version number is put in the header of the font file.
• Added long option names (suggested by Thomas).
• Added support for multi-level composite glyphs.
• TH: Made <fontname> command-line argument optional; default to <ttf-file> with suffix replaced.
• In other/showg added more ways to specify glyphs and the comparison option.

• Fixed the VC++ batch file, added batch file for Cygnus GCC on Windows.
• Removed parentheses from the Version string in AFM files because it does not help StarOffice anyway. StarOffice 5.2 has been reported to have this bug fixed. Added paragraph on StarOffice in FONTS.html.
• Made messages on the '?' option parameter more meaningful (by Johan Vromans).
• Changed the latin1 encoding table to include the Euro sign, Z and z with caron (by Thomas Henlich).
• Improved the smoothing code which occasionally had problems with joining curves. Also fixed a few minor bugs in it.

3.22 -- May 23, 2000

New features:

• Included windows support by Frank Siegert (somewhat amended)
• Added control over verbosity of warnings.
• Added arguments and initialization functions to the language translation routines.
• Added support of planes determined by arguments to the external maps.
• Added compact external maps format (primarily for Eastern fonts).
• Added external maps for Chinese GBK and Big5 encodings (converted from ttf2pfb) as well as maps for other Chinese encodings by Wang Lei.
• Added the idea of buckets to speed up the search in external maps.
• Changed the grouping algorithm for substituted hints: now it creates a bit bigger files but requires smaller hint stack when being rendered.
• Added maximal limit of hint stack depth, glyphs requiring bigger stack get generation of substituted hints disabled. This makes substituted hints safe to use, no more lost glyphs due to hint stack overflow.
• Added the font dump program other/dumpf.
• Changed the testing HTML generator other/lst.pl to use tables.
• Added debugging script other/cntstems.pl to count required hint stack depth for the glyphs.

• Fixed printing of UID in script/trans. Changed the auto-generated UID to be in range 4000000-4999999 which is reserved by Adobe for private use.
• Fixed handling of "cleartomark" in built-in t1asm.
• Added handling of "can't happen" case in straighten() routine which actually happened on strange fonts and caused failure on assertion.
• Made it always include the glyph .notdef in the resulting font.
• Placed the version string in AFM file in parentheses, hopefully that would fix the problem with StarOffice.
• Improved the smoothing code which occasionally had problems with joining curves.

3.21 -- March 1, 2000

New features:

• New Unicode map format with glyph names, by Petr Titera.
• Option to force the Unicode encoding by Petr Titera (I changed it to work on any MS encoding, not only Symbol).
• Slightly tweaked the calculation of hints, should be better now.

• The unicode-sample.map with description of the map formats was lost in the release process, restored and enhanced.
• Renamed the table ISOLatin1Encoding to Fmt3Encoding to reflect the way it is used. Saved the original one for reference purposes. In the new table renamed "quoteright" to "quotesingle" as Thomas Henlich suggested (and he were right).
• In the ISOLatinEncoding table renamed the glyph "grave" at octal 0140 to "quoteleft", "quotesingle" at octal 047 to "quoteright" to conform to the standard as suggested by Martin Trautner).
• Fixed bug in scripts/trans that corrupted the UniqueID record in the translated fonts.
• Fixed bug in interaction of substituted hints with BlueZones. Now the fonts with hint substitution seem to be always at least not worse than without it (well, when they fit in the X11 file size limit).

3.2 -- January 15, 2000

New features:

• Support of the external Unicode re-encoding maps (by Thomas).
• Support for inclusion of all the glyphs from the source file into the resulting file (inspired by Thomas but I re-implemented it to remove the limitation of his implementation: not more than 1024 glyphs).
• The hints substitution. It's an experimental feature yet and needs further work.
• Support for UniqueID and its auto-generation.
• Support for the name-based conversions from Unicode in general and the adobestd "language" in particular.
• Started the split of the source code into multiple files. This needs more work to do it in a cleaner way.
• Better framework for the debugging printout in the converter.
• Utilities to install the fonts in Netscape Navigator/Communicator 4.x.
• Patches for bigger font files in the X11 rasterizer.
• Linux RPM spec-file (by Johan Vromans).
• Added the COPYRIGHT file (BSD-style, as we discussed on the mailing list earlier) and the CHANGES file.
• Creation of the .pfb files from the convert script.
• Changed the .notdef-s in the built-in ISOLatin1Encoding table to some valid names (by Thomas). Thomas also suggested replacing `quoteright' by `quotesingle' but this seems to be against the Adobe ISOLatin1 table.
• New aliases windows-1251 and cp-866 for the Russian encodings: those are expected by Netscape navigator.
• The font comparison program other/cmpf.
• The "magnifying glass" program for glyph outlines: other/showg.
• Other updates of the tools in the `other' subdirectory.
• Added a link to T1LIB in README.
• A few new options in convert.cfg.

• A bug in the outline smoothing code that corrupted some of the fonts (for example, Microsoft Verdana).
• Added explicit `cleartomark' to the end of file, this seems to be compatible with both old and new version of t1asm (suggested by Thomas).
• Added the FontEncoding statement to the AFM files (techincally this was not a bug because this statement is optional but some programs want it).
• A coredump when the converter tried to print a warning (rather ironically) about a weird glyph width.
• Changed the underscores in the font names to dashes (this has been proposed long time ago by Johan Vromans).
• No more glyph names of font names staring with a digit.
• The names of the fonts in font and AFM files are now the same as in the generated Ghostscript Fontmap file.
  Warning: the names in Fontmap have been changed.
• The forceiso script does not corrupt the character and kerning pairs counts any more, and is optional at all.
• Fix for a loop going to 254 instead of 255 (by Thomas).
• Added ':' in the font header (by Thomas).
• A coredump when wrong language name is given (this was also fixed by Thomas but I noticed it too late, after I already fixed it by myself).
• Fixed the links to the Adobe documents in README.

3.13 -- October 18, 1999

New features:

• New option -v for automatic re-scaling based on the vertical size of the font
• Changed the code to use getopt() instead of a home-made version of it.
• Latin2 language support by Szalay Tamas.

• Fix for the bug that made possible calls of malloc(0).
• Refinement of the option -w to prevent extra wide spacing

3.12 -- October 2, 1999

New features:

• Added support for the Bulgarian language (actually, for now just an alias of Russian).
• Added option -w that tries to make sure that the character widths are not too narrow.
• Added the concept of aliased encodings.
• Now the conversion scripts create and install the .afm files too.
• The conversion script removes the intermediate files after installation.
• Added tunables to the conversion script.
• Installation of the Ghostscript fonts can now be done automatically together with the X11 fonts.

• (FINALLY!!!) A correct fix for the infamous Red Hat 6.0 stdio "feature".
• A number of little bugs discovered by a picky SGI compiler (well, maybe some day I'll try to run it through the UnixWare lint and see what happens).
• A diagnostic message about the empty encodings in the convert script was made less cryptic and a bug in the awk sub-script was fixed.
• The .afm creation code now considers the option -t.

3.11 -- May 24, 1999

New features:

• It includes the Turkish (Latin5, ISO8859/9) language support by Turgut Uyar and Baltic (ISO8859/4) languages support by Rihardas Hepas.
• Also the installation script got updated: the configuration parameters are moved to a separate file and the generated fonts.dir files should now be compatible with Xfsft.

3.1 -- March 28, 1999

New features:

• Improved the interaction of the character-level hints and font-level hints

3.0 -- March 6, 1999

New features:

• Added HTML documents.

3.0beta2 -- February 14, 1999

New features:

• Added ability to print the .afm file instead of the font to STDOUT.
• Added the guessing of the /ForceBold parameter that proved to be useful.

• Removed the force-fixed option that proved to be troublesome.

3.0beta1 -- December 11, 1998

New features:

• Added option (passed to t1asm) to create a compressed binary version of the font (A PFB file).

• Versions of handle_post and handle_cmap that deal with some problems with buggy fonts.
• Minor Bug Fixes.

3.0beta-afm -- December 5, 1998

New features:

• Integration of AFM file creation.

3.0beta -- November 15, 1998

New features:

• Added the auto-calculation of the italic angle.

• Fixed a couple of bugs.

3.0alpha -- October 19, 1998

New features:

• Improved (although still not perfect) handling of scaling in composite glyphs
• Automatic correction of outlines to make them more smooth (to correct both rounding errors introduced during conversion and present in the original font)
• Automatic generation of hints (still has lots of space for improvement)
• Automatic generation of BlueValues etc.

• Scaling of fonts to 1000x1000 M-square required by Type1 standard
• Printing out the contours in reverse direction, because TTF directions are different from Type1 ones (that was the major reason why the fonts generated by version 2.2 were rendered so badly in small sizes)

June 22, 1998 (AKA 2.2)

Bux fixes:

• "width" should be "short int" because otherwise: characters with negative widths (e.g. -4) become *very* wide (65532)
• The number of /CharStrings is numglyphs and not numglyphs+1

February 13, 1998

Bux fixes:

• An original Bug Reported by Frank, which was just incorrect syntax in the Type 1 header, managed to creep back into the Feb 04 Version. This has been Fixed in the Feb 13 Version.

February 4, 1998

Bux fixes:

• A workaround was implemented in ttf2pfa by altering the matrix. I suspect I will have to calculate the correct values, as matrix ops are probably not allowed in Type 1 format.

The older history seems to be lost.
