Copy the following script (which uses an undocumented hack and may = [...] Thank you. This is exactly what I wanted. All my tries with gimp-1.3.19 trying to use the 'Alpha' channel (and not a mask) were unsuccessfull. There is no way of painting (or for the matter pasting into) the alpha layer. Creating mask--deleting alpha--editing mask--apply mask is what I used (not with a script), but it is quite cumbersome, and this is why I did post to gimp-devel: so that there may be a possibility to directly edit the alpha channel of a layer (as there is the possibility of directly painting onto only the blue layer, or red or green) in the future. I certainly meant no offense. Meanwhile, your script will serve my needs. I do very small icons, and like to set transparency pixel by pixel. -- JCD
