Hey @sk Would you mind telling me how you do photo dithering over at your image board?

i played around with the various dithering strategies and i landed on ordered dithering. it may not be as accurately representative and well defined as the floyd-steinberg, but i just love the crosshatch aesthetic · 2 years ago

Also surprisingly straightforward to implement yourself https://en.wikipedia.org/wiki/Floyd–Steinberg_dithering · 2 years ago

There is also dither: https://github.com/makeworld-the-better-one/dither (command line wrapper: https://github.com/makeworld-the-better-one/didder) · 2 years ago

👽 sk

for sure! it's not too interesting i'm afraid. it's just using imagemagick under the hood https://github.com/imagemagick/imagemagick

the exact command i use is

convert $INPUT -resize '512x512>' -ordered-dither o2x2,3 $OUTPUT
