It is available from


The latter site also holds older versions of the FreeType library.

See below  for the  relevant snippet  from the  CHANGES file; users of
version 2.4.5 should upgrade immediately.




FreeType 2  is a software  font engine that  is designed to  be small,
efficient,  highly   customizable,  and  portable   while  capable  of
producing high-quality output (glyph images) of most vector and bitmap
font formats.

Note that  FreeType 2 is  a font service  and doesn't provide  APIs to
perform higher-level features, like text layout or graphics processing
(e.g.,  colored  text  rendering,  `hollowing',  etc.).   However,  it
greatly simplifies these tasks by providing a simple, easy to use, and
uniform interface to access the content of font files.

FreeType  2  is  released  under  two open-source  licenses:  our  own
BSD-like FreeType  License and the  GPL.  It can  thus be used  by any
kind of projects, be they proprietary or not.


CHANGES BETWEEN 2.4.5 and 2.4.6


     - For TrueType based fonts, the ascender and descender values were
       incorrect sometimes  (off by a pixel if the ppem value was not a
       multiple of 5).   Depending on the use you might now  experience
       a different  layout; the  change should  result in  better, more
       consistent line spacing.

     - Fix CVE-2011-0226  which causes a  vulnerability while  handling
       Type 1 fonts.

     - BDF fonts  containing  glyphs with negative values  for ENCODING
       were  incorrectly  rejected.  This  bug has  been introduced  in
       FreeType version 2.2.0.

     - David Bevan contributed a major revision of the FreeType stroker

       . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

       . A new  line join style,  FT_STROKER_LINEJOIN_MITER_FIXED,  has
         been introduced to support PostScript and PDF miter joins.

       . FT_STROKER_LINEJOIN_MITER_VARIABLE  has been introduced  as an
         alias for FT_STROKER_LINEJOIN_MITER.

       . Various stroking glitches has been fixed.


       - SFNT bitmap fonts which contain an outline glyph for `.notdef'
         only no longer set the FT_FACE_FLAG_SCALABLE flag.
