Hmmm. I guess I did a doubletake here. Can I do that by creating an 8-bit
black image by hand in picture editor of the space I want opaque, then
setting the maskData of the image I want using it?


If it will work, then how do I do it, i.e., define the maskData of my
finished image to the blackout area I create?

My guess is to get the imageData and then create a maskData based on that and set the maskData.


Alternately, you can get the alphaData and make the maskData based on that. For all I know you can set the maskData to the alphaData and do it on one statement, but I haven't looked at that.
