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 Qt framework.  The
compilation of this application can be disabled with the `--without-qt'
configuration option.


Version 1.8.3 (2019-Apr-09)

  * Support for Mongolian.  The de-facto standard is to render the glyphs
    horizontally (left-to-right) line by line, then rotating each line
    clockwise by 90 degrees.  This allows the usage of ttfautohint.

  * Bug fix: Glyphs with complicated shapes or a large number of outlines
    could be distorted if displayed with FreeType (or stay unhinted if
    viewed on Windows).
