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.
