In the ball bitmap, the ball itself is red while the surrounding area is black. In the mask, the ball is black and the surrounding area is white. My understanding is the mask needs to be black where you want the image to appear. Am I correct?
Yeah that sounds right. It was just a shot in the dark because you hadn't described the mask yet and it would be an easy thing to mix up. Sorry if I just ended up causing confusion.

Erm, isn't it the other way around? I've always used white in masks to show where I want the image, and black for 'transparent'
