)

Public Function New( _ 
   ByVal low As Integer, _

public IntensityDetectCommand( 
   int low,  
   int high,  
   RasterColor inColor,  
   RasterColor outColor,  
   int 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.

Example

Run the IntensityDetectCommand on an image.

using Leadtools.ImageProcessing.Color;

   // Load an image

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "dirty_barcode.jpg")); 
 
   // Prepare the command 
   //Apply the filter. 
   IntensityDetectCommand command = new IntensityDetectCommand(128, 255, new RasterColor(255, 255, 255), new RasterColor(0, 0, 0), IntensityDetectCommandFlags.Master); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
