1 bit is black and white, correct, not greyscale?

If greyscale is ok, I an handle that. However, any function that converts to
black and white is going to have to use some sort of sophisticated algorithm
to get good results and is therefore going to be difficult to wirte,
correct? And since I don't know much about images, and algorithm just yet,
I would be SOL.

It seems odd that Apple would give us this great routine, and then tell us
that basically the file has to be in the format you want to convert to.

Thanks,
Ben
