Dithering Methods

The following are constants for the dithering methods:

Constant

Meaning

None

Use nearest color matching.

FloydStein

Use the Floyd-Steinburg dithering method. Approximate the original color depth by diffusing errors to the four neighboring pixels.

Stucki

Use the Stucki dithering method. This is a variation of the Jarvis method.

Burkes

Use the Burkes dithering method. This is a variation of the Stucki method removing a line of pixels that errors are diffused to.

Sierra

Use the Sierra dithering method. This is a faster variation of the Jarvis method propagating errors to fewer neighboring pixels.

StevensonArce

Use the Stevenson Arce dithering method. This is method is slow but more likely to produce higher quality images.

Jarvis

Use the Jarvis dithering method. Approximate the original color depth by diffusing errors to twelve neighboring pixels. It is slower than the Floyd-Steinburg method.

Ordered

Use ordered dithering, which is faster but less accurate than other dithering methods.

Clustered

Use clustered dithering.

For general information about dithering, refer to Color Resolution and Dithering.
