If you mean alpha-channel, where one image is blended by some amount over another image so that pixels from both images combine, then no, there is no alpha-channel. I am pretty sure that keying is the closest you are going to get. However, you could do a multiply on two images, by 64.64.64, then manually add the pixels for your result. It wouldn't be fast, though.
