Remarks

Each pixel value is converted to its corresponding value in the pixel map. The default pixel map is an identity map an (input pixel value of 0 maps to an output value of 0, 1 to 1, and so on).

The value returned by GetMap is a copy of the pixel map. If you make changes to the returned array, and you want them reflected in the pixel map, you must pass the altered array to SetMap .
