the alpha layer controls transparency, and doesn't have any direct
relation to the RGB values. to add an alpha layer to an image, you can
use a direct convert:
imOut = im.convert("RGBA") # sets alpha to 255
if you have an RGB image, you can also modify it in place
im.putalpha(value) # set alpha to given value
or
im.putalpha(matte) # where matte is a mode "L" image
