ttfautohint 0.97
----------------

by Werner Lemberg <wl@gnu.org>


This project provides a library which takes a TrueType font as the input,
removes its bytecode instructions (if any), and returns a new font where all
glyphs are bytecode hinted using the information given by FreeType's
autohinting module.  The idea is to provide the excellent quality of the
autohinter on platforms which don't use FreeType.

The library has a single API function, `TTF_autohint'; see
`lib/ttfautohint.h' for a detailed description.  Note that the library
itself won't get installed currently.

A command-line interface to the library is the `ttfautohint' program; after
compilation and installation, say

  ttfautohint --help

for usage information, or say

  man ttfautohint

to read its manual page.

A GUI to the library is `ttfautohintGUI'; it uses the Qt4 framework.  The
compilation of this application can be disabled with the `--without-qt'
configuration option.

New in 0.97:

* Improved script support.  Besides Cyrillic and Greek, which are now
  handled separately from Latin, ttfautohint can handle Hebrew.

* Option `-f' now takes a parameter to specify the fallback script.  The
  corresponding long option name has been renamed from `--latin-fallback' to
  `--fallback-script'.

* Work around a bug in display environments that use FreeType 2.5.0 and
  earlier for rendering: Sometimes, the `strong' stem width routine was used
  for DW ClearType (this is, subpixel hinting in FreeType is enabled) even
  if `smooth' was selected while generating the font with ttfautohint.
