Presets, “Input Type”, Clipping, Blending Options, Preview, Merge filter, Split view

  | 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 hue of the pixels in a random pattern. A higher value will increase the average change 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.
