class ColorizeGrayCommand(RasterCommand):
This class is available in the Imaging and above toolkits.
The colors from the input images will be colored as follows: Pixel intensities from 0 - 9999 will be Red. Pixel intensities from 10000 - 19999 will be Green. Pixel intensities from 20000 - 29999 will be Blue. Pixel intensities from 30000 - 39999 will be Cyan. Pixel intensities from 40000 - 49999 will be Magenta. Pixel intensities from 50000 - 65535 will be Yellow. (Note: the Threshold value is ignored for the last entry in the GrayColors array.)
For more information on filling the GrayColors array to obtain this result, refer to the example.
