Color Reduction with dithering
Color reduction with the Dither filter analyzes colors and approximates them using the distribution of black and white dots. The image thus undergoes a dithering of dots, more or less dense, depending on the light and dark colors.
This filter has no parameters. To act on the dither of the dots you can use the Brightness parameter, which darkens or lightens the image. Light colors produce a wider dither, dark colors produce a thicker dither. The check-box to remove isolated dots may damage the dither of the image. With too detailed images this filter is not suitable, because it produces too fragmented tactile images.
