class CreateGrayscaleImageCommand(RasterCommand):
The CreateGrayscaleImageCommand command works by creating a new image in the DestinationImage property from the image passed to the Run method.
The destination image will have either 8, 12, or 16 bits/pixel grayscale values.
When converting to 12-bit or 16-bit grayscale, a Lookup table (LUT) is not used. When converting to 8-bit grayscale, a LUT is used to get the RGB for each input pixel. The grayscale value corresponding to that RGB triple is used in the destination image
LowBit and HighBit are used when converting to 12-bit or 16-bit grayscale, So the appropriate values must set before calling the Run method.
This command does not support 32-bit grayscale images.
This command does not support signed images.
This example loads an image and changes it to 16-bit grayscale.
