Dither

Reduce the number of colors in the image, by reducing the levels per channel (colors and alpha). Different dithering methods can be specified to counteract quantization induced banding.
Red levels
Number of levels for red channel
name: red-levels type: int default: 6 minimum: 2 maximum: 65536 ui-minimum: 2 ui-maximum: 65536 ui-gamma: 3.00 ui-step-small: 1 ui-step-big: 5
Green levels
Number of levels for green channel

Blue levels
Number of levels for blue channel
