But this is per-pixel alpha, which is slower than colorkey transparency, I believe.
In theory it may be, but I haven't found this to be a problem. As a benefit, you get better-looking results due to anti-aliasing of the edges (assuming your alpha channel has been created appropriately, and doesn't just consist of all 0 or 255). Two ways that I have used to create anti-aliased alpha channels: 1) Use the magic wand tool in Photoshop. 2) (more recently) Import the image into Intaglio, draw a path around it, create a masked group, and use Save Selection As. -- Greg
