How it works

Each pixel is rounded to black or white and the rounding error is pushed onto the neighbors still to be processed. Organic and detailed.

Error diffusion weights, as a fraction of 32, by position relative to the current pixel
Current pixel8/324/32
2/324/328/324/322/32
  • The error of the current pixel is spread over 7 neighbors that haven’t been processed yet.
  • All of the error is carried forward.
  • Rows are scanned in alternating directions (serpentine), which avoids diagonal streaks.
