Do I have to create one??? John, Your own post has several clues to your problem. What you have there is a black&white display... i.e. two colors, always black & white. all you can do with these displays is modify how the data is converted to 1-bit. specifically, see the FLOYD, ORDERED, and THRESHOLD keywords. to avoid the error message, check !d.n_colors... if it's 2, then don't try to load a color map. hope this helps. -steve
