Your best bet is to draw the image in an offscreen window, and then
blit it to the screen. That will save you much time, as well as the
pain of having to parse the image every time you want to draw it.

You'll want to implement the blit methods - those will let you transfer
data en-mass to your device (and let you do any bit mangling you need
along the way).
