	注意
	These options are described in 第 2 节 “Common Features”.

Dulling

This slider (1 -8) controls how much the new pixel color value is allowed to be applied compared to the existing color. A low dulling will give an important hue variation. A high dulling will give a weak variation.

Hue

This slider changes the color of the pixels in a random pattern. It selects an increasing available color range in the HSV color wheel starting from the original pixel color.

Saturation

This slider increases saturation of scattered pixels.

Value

This slider increases brightness of scattered pixels.

Random seed, New Seed

This option controls the randomness of the filter. The Random seed box lets you manually enter a seed for the randomization algorithm used. You can also generate a random seed by pressing the New Seed button. If the same random seed is used in the same situation, the filter produces exactly the same results. A different random seed produces different results.
