ttfautohint 1.3 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 that 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 that 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 1.3 (2015-Jan-06)

* Keywords in control instruction files can be more verbose to increase
  readability.  You can now use `left`, `right`, `nodir`, `point`, `touch`,
  `xshift`, and `yshift` for `l`, `r`, `n`, `p`, `t, `x`, and `y`,

* A new control instruction keyword `touch` was added to apply delta
  instructions before the final IUP bytecode commands, also `touching' the
  affected points (to use the TrueType instructions terminology).  Such
  deltas *do* work even with ClearType if applied to the non-ClearType

* Support for the Telugu script.

* The amount of information about ttfautohint and its parameters that gets
  added to the `name` table by default has been reduced.  A new option
  `--detailed-info` restores the previous behaviour.

* ttfautohintGUI crashed if not used with a control instruction file.

* ttfautohintGUI now correctly switches to a horizontal two-column layout if
  the standard one-column layout would exceed the screen height.

* A new option `--family-suffix` makes it possible to append a suffix to a
  font's family name in the `name` table.  This can be useful during the
  development process: It helps the operating system to simultaneously
  display several instances of a font that are processed with different
  ttfautohint parameters.

* The new library option `info-post-callback` helps in processing data from
  the `name` table.
