My Shareware image viewer Retriever (for W95/NT) does that (reduce to
anything between 256 and 2 colors), and I believe that it does it better
than anything else, if you check the right boxes for your image. Sorry it's
no toolkit, just a desktop application.

1. Contrast / Color Reduction Utilities?

Hello,

   I'm looking for Utilities on Unix that can work with ppm/pbm/pnm
packages that would let me:

1. Change the Brightness / Contrast of an image
2. Reduce the number of color in an image (with different differing
options)

   If you know there is any such utility, please let me know. E-mail is
prefered. Thank you!

Regards,
CT Yen.
