ttfautohint 1.4.1 has been released.

The source tarball, statically-linked binaries for Win32 (TTY and GUI) and
OS X (TTY only) are available from


Instructions to build the GUI version on OS X can be found at

This project provides a library which takes a TrueType font as the input,
remove its bytecode instructions (if any), and return 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.


Version 1.4.1 (2015-Oct-17)

* A bug in handling control instruction files could cause severe glyph
  shape distortions of accent-like glyphs.  All users should update.

Version 1.4 (2015-Oct-04)

* Support for Thai and Lao scripts.

* Support for the Arabic script.

* Better support for scripts that contain superscript-like and
  subscript-like glyphs, e.g., the International Phonetic Alphabet (IPA).

* Accents and other `non-base' glyphs are now hinted without snapping to
  blue zones.

* A new control instruction syntax form was added to adjust the mapping
  between glyphs and styles.  Right now, its usage is quite limited; a
  forthcoming version will give much more flexibility.

* The `touch` keyword in a delta instructions file was buggy: If used for a
  point `P` at a ppem value `s`, it sometimes led to unwanted movements
  of `P` for ppem values unequal to `s`, thus causing outline distortions.
