LowThreshold Property

Summary

Gets or sets a value that represents the lowest intensity to detect.

Syntax

Objective-C

C++/CLI

Java

Python

public int LowThreshold { get; set; }

@property (nonatomic, assign) NSUInteger lowThreshold;

public int getLowThreshold(); 
public void setLowThreshold( 
   int intValue 
);

public: 
property int LowThreshold { 
   int get(); 
   void set (    int ); 
}

LowThreshold # get and set (IntensityDetectCommand)

Property Value

Lowest intensity to detect. Possible values are from 0 to 255.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color;

   // Prepare the command 
   IntensityDetectCommand command = new IntensityDetectCommand(); 
   //Apply the filter. 
   command.LowThreshold = 128; 
   command.HighThreshold = 255; 
   command.InColor = new RasterColor(255, 255, 255);
