You shouldn't be afraid of doing raster graphics in Python; you'll just need to be familiar with Numpy. You can easily compose layers, mask out operations to only happen on one channel, etc., and code it all up in Python while getting C-level speed. The gotcha, if you use PIL, is that you're going to have to use tostring() and fromstring() to get the array data back and forth between numpy and PIL. An alternative is to use openGL, as others have suggested, and blit into a texture. If you use pyglet, for instance, you can use Andrew Straw's pygarrayimage module to convert a numpy array directly into a texture. I wouldn't recommend Cairo for doing pixel-level ops, since it is a vector graphics library. -Peter -- http://mail.python.org/mailman/listinfo/python-list
