Is it possible to change individual pixels on an image without having to do XMapRaised each time ? Each map raise takes a long time, and we're trying to do pixel updates in real time. I think this will involve writing to the image memory directly, but I don't know if X provides a mechanism for doing so.

Is it possible to change individual pixels on an image without having to do XMapRaised each time ? I know I haven't had much sleep lately, but this question makes absolutely no sense to me. What does mapping and raising a window have to do with changing pixels in an image? What exactly are you trying to do, and why?
