Hi, I have two 24-bit images with the same dimensions. The second one represents the alpha channel of the first one. How can I load the second image (one of the RGB channels or maybe greyscale) into the alpha channel of the first image?
I tried it with 2 layers and "multiply", but that just multiplies the RGB values together. Is it possible to copy channels into another, so that I could copy the R channel into the alpha channel of the second image and then use "multiply" with 2 layers?
Thanks,
Mete
