I remember a while ago reading about an alternative (aka faster) way to perform a "getPixel()-ish" method. Problem is, I don't remember where I read that, and I've searched thoroughly.. I think.
The answer had something to do with locking the Bitmap in memory, or something like that. I need to run getPixel() multiple times "per-tick," which is very costly it seems.
Does anyone know what I'm talking about?
