Each area is filled with the average color of all pixels contained within the area. Pops up a dialog box which prompts for either a single value ' m ', or a pair of values ' m x n '. In the case of the single value, each pixel in the image is swapped with some other random pixel located within a distance of m pixels from the first pixel. If two values are entered, each pixel is swapped with another pixel located within m , n of the original pixel. This can produce an interesting 'de-rez' effect.
