X-Snort: uid=0(root) gid=0(root) 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, -- Sam.
