Increases or decreases the brightness in the image by multiplying the colors in a specific image by a factoring value divided by 100.

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;
For more information, refer to Changing Brightness and Contrast.
Run the MultiplyCommand on an image with factor = 1.51.
