WebApr 19, 2024 · Dither matrix are power-of-2 matrix whose elements can be considered as threshold. In these matrices, consecutive threshold values are located far apart spatially, which gives the perception of a progressive variation. The values inside the matrix indicate how likely a pixel will be turned on. WebJan 6, 2024 · Quickstart This library performs image dithering.
