xcftopnm - convert xcf files to pnm files
xcftopnm [-layer N] [xcffile]
This is a rough and slow implementation of a xcf2pnm filter, to be used by other programs that want to be able to read xcf images. If ussage increases this program will doubtlessly be sped up as well.
-layer NSelect the Nth layer, instead of flattening the whole image.
