There's currently no way of doing this that I know of. (Sorry.) I was
holding off on answering your first message in the hope that one of our
clever listmembers would come up with a method, but....
You could change the alphaData of the image to display only those portions
that you want seen, but of course that would require some fancy footwork
with determining algorithmically which pixels to blank and which to leave
alone. Your idea of assembling masking graphics might actually be simpler.
