- There are a set of conversion routines which convert most common graphics formats
- into a portable format and from this portable format to the common formats. This
- allows you to convert format #1 to the portable format and then the portable format
- to format #2. This use of an intermediate format reduces the total number of
- conversion routines needed (at the cost that you must do two conversions).
- These are most commonly called the 'portable bit-map' routines. You should be able
- to find them at most ftp sites. I suggest searching for pbm (portable bit-map) and
- ppm (portable pix-map?).
-
- With those routines you'll be able to go from IFF to GIF.
- I use the above conversion routine 'ilbmtoppm' to convert my IFF images to PPM images
- then use the conversion routine 'ppmtogit' to convert those to GIFs.
-
- For converting to JPEG images I use the 1st routine mentioned above (i.e. ilbmtoppm)
- and then use a completely separate conversion routine 'cjpeg' to convert that to JPEG.
- You'd find cjpeg near where-ever you find the pbm/ppm conversion routines.
-
- To go from IFF to JPEG I use the 1st of the PPM routines from above followed by
- another conversion routine named cjpeg. cjpeg converts a PPM image (amoung others)
- to JPEG. It should be available whereever you find the PBM stuff.
