In my response, I had a cut-n-paste error in the last code-segment. The
(gimp-drawable-set-pixel drawable 1 1 4 (color-as-bytes red blue green
should be changed to:
(gimp-drawable-set-pixel drawable x-coord y-coord 4 (color-as-bytes
red blue green alpha))
The "4" in the line refers to the bytes-per-pixel and would be "2" if
the drawable were grayscale. A '(grayscale-as-bytes value alpha)'
function should then be defined to create a 2-byte array.
