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. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
