  <h2>
    Introduction
  </h2>

  <p>This is the third section of the FreeType&nbsp;2 tutorial.  It
  describes how to deal with various internals of the library like</p>

  <ul>
    <li>the module interface</li>
    <li>functions for manipulating vector outlines</li>
    <li>font driver issues</li>
    <li>interaction with renderers using callbacks</li>
    <li>accessing font specific data, for example PostScript font
    dictionaries and TrueType tables</li>
  </ul>

  <p>None of these items have been written yet.</p>

  <h2>
    Examples
  </h2>

  <p><a href="mailto:erik@timetrap.se">Erik Möller</a> contributed a very
  nice C++ example which shows renderer callbacks in action to draw a
  coloured glyph with a differently coloured outline.  The source code can
  be found <a href="example2.cpp">here</a>.</p>

  <p><a href="example3.cpp">Another example</a> demonstrates how to use
  FreeType's stand-alone rasterizer, <tt>ftraster.c</tt>, both in B/W and
  5-levels gray mode.  You need files from FreeType version 2.3.10 or
  newer.</p>

  <p><a href="mailto:gsmiko@gmail.com">Róbert Márki</a> contributed a small
  <a href="example4.cpp">Qt demonstration program</a> (together with its <a
  href="example4.pro">qmake file</a>) which shows both direct rendering with
  a callback and rendering with a buffer, yielding the same result.  You
  need FreeType 2.4.3 or newer.</p>
