DitherMode

roxlap_render

Enum DitherMode 

Source 
pub enum DitherMode {
    None,
    Bayer4x4,
    BlueNoise,
}
Expand description

Dither applied before the posterize quantization (RP.2), to break up banding and turn it into a stable retro pattern instead of crawling edges. Indexed by the logical pixel, so each hard pixel still resolves to one colour.

Variants§

§

None

No dither — plain round-to-nearest quantization (hard banding).

§

Bayer4x4

Classic 4×4 ordered (Bayer) dither — the cross-hatch console look.

§

BlueNoise

Interleaved-gradient noise — a cheap, texture-free blue-noise-ish stochastic dither (finer than Bayer, no repeating grid).
