I can tell you as soon as i have given that a try. Color depth however 
should not be the problem, as i can reduce the depth beforehand (just 
using a range from 0..x instead of 0..255), even if not reducing the 
colors it will work, but several identic chars may then appear in my 
charset of course, but for evaluation this should not matter too much.

Kindest regards,
