Also, presumably this solution will threshold the grayscale image at 128
(assuming an 8-bit grayscale), so you might want to apply a thresholding
LookupOp to (a copy of) the original grayscale image before rendering it
into the bitmap, if you need a different threshold.
Question: will setting the KEY_DITHERING rendering hint make any difference
to the way pixmaps are drawn into bitmaps?
Cheers,
Pete
