<p>The FreeType project wants to become part
of <a href="https://developers.google.com/open-source/gsoc/">Google
Summer of Code</a>. Here is our ideas list.</p>
<dl>
<dt>Improve fuzzing for FreeType</dt>
<dd>
<p>Description will follow.</p>
<p><em>Difficulty: </em>medium. <em>Requirements:</em>
C, C++, Unix build tools. <em>Potential mentors:</em>
Kostya Serebryany (Google), Werner Lemberg
(FreeType).</p>
</dd>
</dl>
<dl>
<dt>Develop a test framework for checking FreeType's
rendering output</dt>
<dd>
<p>Right now, FreeType's rendering results of the
current development version are not systematically
compared to a baseline version. This is problematic,
since rendering regressions can be very easily missed
due to subtle differences.</p>
<p>The idea is to select a representative set of
reference fonts from font corpora (which already exist
mainly for fuzzing). The fonts are used to produce
glyph images for various sizes and rendering modes
(anti-aliased, B/W, native hinting, auto-hinting,
etc.). FreeType can already produce MD5 checksums of
glyph images as part of its debugging output; these
values should be compared against a baseline version
of rendering results. If there are differences, HTML
pages should be generated that contain comparison
images of the baseline's and the current development
version's rendering result, ideally indicating how
large the differences between the images are by using
some yet to be defined measure.</p>
<p><em>Difficulty:</em> medium. <em>Requirements:</em>
C, Unix build tools. <em>Potential mentors:</em>
Werner Lemberg, Alexei Podtelezhnikov, Toshiya Suzuki
(FreeType).</p>
