WebFeb 5, 2012 · The dithering is coarser, but has fewer visual artifacts. It is slower than Floyd–Steinberg dithering because it distributes errors among 12 nearby pixels instead of 4 nearby pixels for Floyd–Steinberg. Stucki dithering is based on the above, but is slightly faster. Its output tends to be clean and sharp.
