Can you post your image in a format that contains the alpha channel you want to edit. Gimp .xcf or maybe .png

Quote:What i want to do is to edit alpha channel as a curve, but based on Red and Green channel
Is this possible ? An alpha channel is just a greyscale mask, nothing in there to adjust red or green ?
