As I mentioned in another posting, your workaround (also suggested by Stephen Woodbridge) works fine for my needs. Nevertheless, do you feel that this is a GD bug that ought to be reported to them? I suppose it depends on your precise interpretation of what quantization should do under certain circumstances. But in this case as applied to image processing, I'm inclined to think that if I only request a single color and a quantization limit of 256 colors (or really any request <= 256 colors in this case), that the color(s) requested should be returned without modification. - Rich -- View this message in context: http://www.nabble.com/Color-shifts-using-QUANTIZE_COLORS%3D256-tf2080351.html#a14137470 Sent from the Mapserver - User mailing list archive at Nabble.com.
