Floyd-Steinburg Dither
The Floyd-Steinburg Dither option instructs Image Convert to dither the images when re-encoding them to the target palette. Dithering can be used in any of the output color depths, with or without a custom palette. When an optimal palette is created for multiple images, the actual colors contained in the final palette may not exactly match the original image colors. Likewise, when Image Convert is outputting bitmaps for 16-color targets using input images that contain 256 or more colors, Image Convert must translate those original colors into the best possible representation using only the 16-color palette.
The dithering option tells Image Convert how to convert the original image colors to the new system palette colors. If dithering is selected, Image Convert will pick colors such that the average value in each multi-pixel area is equal to the average value of the original input colors for the same multi-pixel area. If dithering is disabled, Image Convert will simply translate each pixel into its nearest color in the target palette.
