The answer I hear is that OJPEG support does not work because of conflicts in the spec. You might try what I did--closely examine the way OJPEG was implemented in the files you must work with, extract from them a JPEG file which you write to a temp file on disk, then do the decompression with libjpeg. -------------------------------------------------------------------------- Thad Humphries "Microsoft...
