I would suggest taking a fairly trivial image format (say pnm), and stripping it's plug-in save & load routines, and replacing them with your custom routines. The source code for the pnm plug-in is in plug-ins/common/pnm.c. Hope this helps, Dave. -- David Neary, Marseille, France E-Mail: bolsh@xxxxxxxx
