PNG Compression
I use the following two tools:
- AdvanceCOMP <a href="http://advancemame.sourceforge.net/comp-readme.html">http://advancemame.sourceforge.net/comp-readme.html</a>
- OptiPNG <a href="http://optipng.sourceforge.net/">http://optipng.sourceforge.net/</a>
I run the following code in each graphics directory:
<pre><code>
advpng -z4 *.png
optipng -o7 *.png
</code></pre>
