Perhaps you might try creating an "empty" NSBitmapImageRep with the
size and pixel attributes you need. Then, use the resultant object as
a graphic context and draw your CIImage into that. The Reducer sample
code does something similar to this. I can imagine that this process

it's the example in the Core Animation Programming Guide, last
chapter. Source isn't available at the moment other than in the book.
It's text laid over a QCCompositionLayer that is running.
