Make alpha dependent on RGB
#5
Ok, thank you. From your advice i learnt that greyscale copy gives me alpha i want after i invert red channel. So not exactly what i was looking for, but works good enough i guess. I will see at more complicated images.

Yes, its for game which uses alpha channel in normal image to calculate snow coverage.
