Syntax

Objective-C

C++/CLI

Java

Python

public int HighThreshold { get; set; }

@property (nonatomic, assign) NSUInteger highThreshold;

public int getHighThreshold(); 
public void setHighThreshold( 
   int intValue 
);

Property Value

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

Example

Java

using Leadtools;

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);
