Hi,
I’ve got a set of black and white images that I’d like to ad an alpha channel to to make it a black and alpha image – where the grey pixels are all actually black with a degree of alpha. The effect would be similar to using the screen effect on the layer allowing the layer below to show through the white completly and through the greys as if they were black pixels with a degree of alpha. I need this so that I can save out the images as transparent PNGs for use in Flash and other programs.
Can I do it with a plugin? or by a fancy select / alpha channel method?
Any help appreciated
Cheers
Guy
