Members

MemberDescription
BayerUses the Bayer algorithm for dithering, looks most like newsprint often used with black and white. Produces a patterned effect. Which may compress better than Burkes or Floyd Steinberg with some files. Bayer Dithering.
BurkesUses the Burkes algorithm for dithering, very similar to Floyd Steinberg. Burkes Dithering
FloydSteinburgUse the Floyd Steinberg algorithm for dithering, this uses a random dot pattern that looks the best, but may not compress as well depending on both the image content and the compression method used. Floyd Steinburg Dithering
NoDitheringNo Dithering, map each pixel to closest pixel in palette. No Dithering.

Remarks

Different palette options for adjusting the bit depth: of the image using the ModifyBitDepthCommand DitherOption.

With standard palettes choosing a dithering option will yield the best results. With an Octree palette it may be possible to choose No Dithering. The advantage of choosing No Dithering for Run Length Encoding Schemes (like gif) is that the compressed image file may be smaller.
