Compress PNG images files using three programs : Input Img -> TruePNG -> zoflipng -> deflopt -> Output Img
<?xml version="1.0" encoding="utf-8"?>
<root>
<prog out="examples/result/$FILE$-new.png" exe="examples/bin/TruePNG" arg="/out $OUT$ /o max $IN$">
<prog out="examples/result/$FILE$.png" exe="examples/bin/zopflipng" arg="-y -m
--filters=01234mepb --lossy_transparent $IN$ $OUT$">
<prog out="examples/result/$FILE$.png" exe="examples/bin/deflopt" arg="$IN$" />
</prog>
</prog>
</root>Another example where you can generate multiple output images with one images. In this case one image is compressed with TruePNG and the other use zopflipng.
