Netpbm has lots of things to offer, including a PSNR measurement tool
(pnmpsnr), a histogram tool (ppmhist) and other nifties. For color space
conversions, the tiff toolchain offers a tool to apply an ICC color
profile to a given image (tifficc) that can be used. netpbm also
includes tools for dithering (ppmdither). You can get the sources, so
modify all that to your needs.

So long,
