@mbtech-nl/bitmap1bpp bitmaps for thermal printers

Dithering, multi-plane colour, transforms — zero runtime dependencies, browser-clean.

Six dither methods + threshold

Floyd–Steinberg, Atkinson, Stucki, Jarvis–Judice–Ninke, Bayer 4×4 / 8×8, plus hard threshold. Visual gallery shows each side-by-side.

Multi-plane colour

Render to one 1bpp bitmap per palette entry (Brother QL-800 red+black, two-colour DYMO/Zebra). Mutually-exclusive output guaranteed.

How it works

Tone controls

autoLevels for low-contrast scans, gamma for per-printer darkness calibration, custom luminance weights for unusual sources.

Tune output

Pure TypeScript, zero deps

No DOM APIs, no runtime dependencies. Runs in modern browsers and Node.js. The interactive playground on this site uses the same code that ships to npm.
