Boolean None No No Whether to dither colors when exporting.

When images are exported at a reduced color depth, they can be dithered. Dithering uses a scattering of pixels of different colors to approximate colors that are not available. This parameter allows you to override the default dither setting - that of the canvas.

In general it is a good idea to dither images like photographs which contain smooth gradations of colors. It is best not to dither 'Posterized' images containing blocks of colors.
