                                 int rgb)

Description copied from class: PixelBuffer

Same as drawPicture, but only uses the alpha channel of the Picture, and is allowed to destructively modify the RGB channels of the Picture in the process. This method may assume that the RGB channels of the image are all zero IFF it restores this invariant before returning.
