- There is (don't ask me where) a ppmtoiff24 which could help you.
- Also, the Amiga-Version of ppmtoilbm supports what you want, and
- does only HAM with the option -HAMFORCE.
-
- Raw to Iff ... Good idea :) Should be quite easy with the iff-library...
-
- Well and Gif to Iff won't be nice, most Gif-Pics only have 256 colors, though
- Gif supports 24 Bit (noone actually use this..)

- Hopla ? Unix side.. Hm Execpt for pbm-plus you might try the URTools..
- Indeed ADPro (and the Amiga Version of Pbmplus, avail via ftp
- from ftp.informatik.uni-oldenburg.de) do support raw to iff, ADPro does NOT
- (grmbl) support PPM but QRT (ppmtoqrt .. :-)
