图 17.161. Example of applying the “Pick” filter

Original image

Filter applied

The Pick filter replaces each affected pixel by a pixel value randomly chosen from its eight neighbors and itself (from a 3×3 square the pixel is center of). All or only some pixels in an active layer or selection are affected, the percentage of affected pixels is determined by the Randomization (%) option.

图 17.162. “Pick” filter options

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

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

Randomization (%)

  This slider represents the percentage of pixels of the active layer or selection which will be picked. The higher value, the more pixels are picked.

Repeat

  This slider represents the number of times the filter will be applied. Higher values result in more picking, pixel values being transferred farther away.

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.
