public IntensityDetectCommand(

   int high, 
   RasterColor inColor, 
   RasterColor outColor, 
   int channel
)

function IntensityDetectCommand( 
   low ,

   inColor ,
   outColor ,
   channel 
)

public:
IntensityDetectCommand( 
   int low,
   int high,
   RasterColor inColor,
   RasterColor outColor,
   IntensityDetectCommandFlags channel
)

Parameters

low: Lowest intensity to detect. Possible values are between 0 and 255.
high: Highest intensity to detect. Possible values are between 0 and 255.
inColor: Color used to fill those pixels having an intensity value between LowThreshold and HighThreshold. This parameter has no effect if the Channel property is set to IntensityDetectCommandFlags.Master. If for example the Channel property is set to IntensityDetectCommandFlags.Red, then the red component of InColor will be used to fill the pixels having a red component value between LowThreshold and HighThreshold.
outColor: Used to fill those pixels having an intensity value less than LowThreshold or greater than HighThreshold. This parameter has no effect if the Channel property is IntensityDetectCommandFlags.Master. If for example the Channel property is set to IntensityDetectCommandFlags.Red, then the red component of OutColor will be used to fill the pixels having a red component value less than LowThreshold or greater than HighThreshold.
channel: Flag that indicates the channel to process.

Run the IntensityDetectCommand on an image.
