C++
public class LightCommand : RasterCommand 
  
Public Class LightCommand  
   Inherits RasterCommand 
public ref class LightCommand : public RasterCommand   

Remarks
  • This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.

Example

Run the LightCommand on an image to change the red color by rotating its hue 90 degree.
