public class IntensityDetectCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class IntensityDetectCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As IntensityDetectCommand

public sealed class IntensityDetectCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTIntensityDetectCommand : LTRasterCommand

public class IntensityDetectCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.IntensityDetectCommand()

public ref class IntensityDetectCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

The image is divided into two parts, inner and outer according to the values of the LowThreshold property and the HighThreshold property.
The class can process 2 or more channels at a time by OR-ing two or more flags.
This class supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.
This command supports unsigned data images, but not signed ones.

For more information, refer to Correcting Colors.

For more information, refer to Detecting and Enhancing Edges and Lines.

Run the IntensityDetectCommand on an image.
