Java
Public Function New( _ 
   ByVal channel As RasterColorChannel, _ 
   ByVal start As Integer, _ 
   ByVal end As Integer _ 
) 
- (instancetype)initWithChannel:(LTRasterColorChannel)channel 
                          start:(NSInteger)start 
                            end:(NSInteger)end 
public StatisticsInformationCommand( 
   RasterColorChannel channel,  
   int start,  
   int end 
) 
public: 
StatisticsInformationCommand(  
   RasterColorChannel channel, 
   int start, 
   int end 
) 

Parameters

channel
The channel for which to get the information. This value is ignored if the image is 12 or 16-bit grayscale.

start
Indicates the beginning color value of the range for the evaluation. This property only accepts positive values.

end
Indicates the ending color value of the range for the evaluation. This property only accepts positive values.

Example

Run the StatisticsInformationCommand on an image.
