I am writing a new gif decoder for the apple IIGS (I know- dumb idea)
but I am looking for some kind of algorithm to take 256 color image
and get the best possible 16 color approximation.
Time is not a factor since i will decode/color compress/encode on a unix
system before actually using the image.
If anyone knows of an algorithm to do this, please mail or post it for me.
                            thanks,
