The Pick filter replaces each affected pixel by a pixel value randomly chosen from its eight neighbours 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.
Controls randomness of picking. If the same random seed in the same situation is used, the filter produces exactly the same results. A different random seed produces different results. Random seed can be entered manually or generated randomly by pressing button.
When the Randomize option is checked, random seed cannot be entered manually, but is randomly generated each time the filter is run. If it is not checked, the filter remembers the last random seed used.
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.
This slider represents the number of times the filter will be applied. Higher values result in more picking, pixel values being transferred farther away.
