The following are constants for the dithering methods:
Constant |
Meaning |
Use nearest color matching. |
|
Use the Floyd-Steinburg dithering method. Approximate the original color depth by diffusing errors to the four neighboring pixels. |
|
Use the Stucki dithering method. This is a variation of the Jarvis method. |
|
Use the Burkes dithering method. This is a variation of the Stucki method removing a line of pixels that errors are diffused to. |
|
Use the Sierra dithering method. This is a faster variation of the Jarvis method propagating errors to fewer neighboring pixels. |
|
Use the Stevenson Arce dithering method. This is method is slow but more likely to produce higher quality images. |
|
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. |
|
Use ordered dithering, which is faster but less accurate than other dithering methods. |
|
Use clustered dithering. |
