predithering JPEG image for iliad
Say, I have a JPEG photo image with lots of colours. Grayscale or colour one. When I load it on Iliad it looks pretty ugly. Is there a smart color reducing / predithering linux pipeline that image gurus out there could advice? Manual tweaks in gimp are not welcome, but I can do it as a last resort. Can ImageMagick convert(1) be told about what the iliad's palette is?
