Frequently asked questions
What is dithering?
Dithering simulates additional colors on a limited palette by scattering colored pixels in patterns the eye blends. Used heavily in early games, e-paper, and newsprint.
Which algorithm is the default?
Floyd-Steinberg is the default because it produces balanced, natural-looking results with good edge preservation and is the most widely recognized.
What are the retro palettes?
The built-in choices are curated, retro-inspired palettes for limited-color rendering. The NES-inspired option currently uses 16 colors; it is not a complete hardware palette reproduction.
Why pixel scale?
Pixel scale enlarges each processed sample into a visible block, creating a chunkier pixel-art appearance. It does not add new image detail.
