This tool performs a gamma colour correction transform on an input image (input), such that each input pixel value (zin) is mapped to the corresponding output value (zout) as:

zout = zingamma

The user must specify the value of the gamma parameter. The input image may be of either a greyscale or RGB colour composite data type.
