strength

: (`float`) The strength at which to apply the dithering matrix, typically a value in the range [0, 1]. A value of `1.0` applies the dithering matrix at 100% strength (no modifification of the dither matrix). The `strength` is inversely proportional to contrast; reducing the strength increases the contrast. Setting `strength` to a value such as `0.8` can be useful to reduce noise in the dithered image. Default is `1.0`.
