atkinson-dithering

High-Throughput Imageboard Streaming & Archival Engine — Async Python/aiohttp, SQLite WAL, and 1-bit Atkinson error diffusion quantizer.

Nine dithering algorithms with their spectral and tonal properties measured rather than asserted. Bayer, blue noise, five error-diffusion kernels, Riemersma and halftoning in pure Python.

Retro image dithering in your browser: 1-bit, Game Boy, CGA and sepia looks with Floyd-Steinberg, Atkinson, Bayer and halftone. A single static page, no build step, nothing uploaded.
