Thanks everyone for the suggestions.<div><br></div><div>Stephen, to answer your question, I want to be able to change the text independently. The letter d, for example, I might want to show sometimes in white, red, or green. I guess I could make a pic for each though.<br>

Ideally, I'd just call this once and put up huge string full of newlines to represent a block of text. My problem is that I want to have control of the color of each character in this block of text. It seems to me that the color controls for draw-text are applied to the entire block at once. Should I just call draw-text for each character in the block, individually assigning color? That seems to be very slow computationally, not to mention more work on the poor coder.<br>
<br>
</div>Are characters and their colors orthogonal? That is, can any character appear in any color, or does a particular character always appear in the same color? If the latter, I would just create a bunch of images up front and place them at the desired (x,y) coordinates directly, rather than re-rendering the text every time. That'll actually be faster.<br>
