pixel-art

Floyd-Steinberg dithering converts images to pixel art by diffusing quantization errors to neighboring pixels, preserving detail while enforcing a limited retro palette. This approach maintains visual fidelity when mapping high-color images to strict hardware or artistic color constraints.

Yes, pixel art animations are supported via a dedicated video module utilizing ffmpeg for encoding. It applies procedural effects to still images and exports the resulting retro-styled sequences directly as MP4 or GIF files.

Pillow and ffmpeg are required dependencies. Pillow handles core image processing tasks like adaptive color quantization and pixel-grid resizing, while ffmpeg is required specifically for encoding pixel art animations to MP4 or GIF.

Available retro palettes include hardware and artistic presets for NES, Game Boy, PICO-8, and C64. These named palettes enforce strict color quantization, ensuring the converted pixel art accurately reflects specific vintage console aesthetics.

The best way to apply dithering for a retro style is using Floyd-Steinberg error diffusion combined with pixel-grid-centric resizing. This method preserves authentic retro aesthetics by accurately mapping continuous tones to limited era palettes.
