class InvertCommand(RasterCommand):
This command changes the image data. If the image has a LUT, the command will work on the LUT not the image data. If the image has a LUT and you want to work on the image data, first disable the use of the LUT by setting the UseLookupTable Property to FALSE. After you are finished applying the command, restore the use of the LUT by setting the UseLookupTable Property to TRUE again. See the following snippet:
image.UseLookupTable = FALSE;
InvertCmd.Run(image);
image.UseLookupTable = TRUE;
For more information, refer to Correcting Colors.
