[magick-developers] about ImageMagick's dithering on a Hilbert-Peano curve

   Dear developers,

   Each time I run "convert src.png -monochrome dest.png" and see the
result I want to cry. I have always wondered why ImageMagick was giving
Riemersma so much credit by using a dithering method (from the C/C++
Users Journal) that was never peer-reviewed by people of the field and
gives so mediocre results. Parsing the image along a fractal curve is
elegant and interesting, but propagating the error along the very same
curve is nonsensical. Even Floyd-Steinberg's artifacts seem preferrable.
Is there a way to convince the team to use something else as the default
dithering method?

Regards,
