This command distorts an image using different random methods. Parameter fields look different for the three available random distortion methods. You can select any of 3 methods of the random distortion from the list available in the Type field.
 |
Excitation. Image pixels are randomly mixed inside the areas of the selected size. This tool lets you simulate a painting made with wide strokes. The average size of the area inside which the pixels are mixed is selected in the Grain fields. The depth of distortion is selected by the Depth control. | |
 |
Erosion. In this case the distortion is more graduate than in the previous one. The Scale field sets the size of the distortion while the Depth field controls how heavy the distortion is. | |
 |
Ripples. This is the most smooth and gradual distortion simulating a reflection in water with irregular ripples. The Grain field is used to set an average size of a ripple, the Depth control sets the ripples' magnitude. |
