There's a gdk-pixbuf-based PNG decoder in libgcj's javax.imageio
implementation. No encoder though.
How about the imageio stuff from the java-gui-branch[1]? I've
successfully rendered PNG images using the java-gui-20050128-branch, so
this should be available in gcc4 as well.
Probably the most efficient way to get a GPL-compatible Java PNG
encoder is to package JMagick.
Before libgcj got imageio writing support, I also used PndEncoder[2],
which is a pure-java encoder (LGPL).
