 My answer does not address your question directly, since a good answer has already been given. I just wanted to remind you that if you are doing this to conserve space you will only get a gain of 6x at the expense of a very significant quality loss (at least on photographic images). A compression such as JPEG can give you a gain of 20x without losing nearly as much quality (in fact very little quality loss), and I think that even at 50x compression ratio it will still have better quality than any 4bpp BMP diethering. There is a number of JPEG libraries out there, some highly optimized (like INTEL's). I hope this helps, Rogério
