One thing to remember when building an App that does this that when you draw to an offscreen buffer there is a bug in the framework that makes it leak memory equal to the size of the image. I once built an app that, I kid you not, leaked about 200MB/sec.

I realize that CIImage isn't really an "image", more of a recipe for how to
draw an image. Thus, couldn't I draw the image to an off-screen buffer and
then read the data from there?


Again, any suggestions would be much appreciated.
