I did a paper and presentation for GUADEC last year on the subject which is online here: http://dneary.free.fr/guadec-paper/ http://developer.gimp.org contains the full API docs for libgimp. Finally, I learned a lot from the existing plug-ins. If you were to pick one of each main type (file plug-in, image plug-in and informational plug-in), I would reccommend pnm, edge and colorcube respectively. Cheers, Dave. -- Dave Neary Lyon, France
