class MultiplyCommand(RasterCommand):
If the image has a LUT and you want to work on the image data, set RasterImage.UseLookupTable to false. Then, after calling the method, reset the UselookupTable property to true, as follows:
rasterImage.UseLookupTable = false;
Method(rasterImage);
rasterImage.UseLookupTable = true;
