Threshold Property

Summary

Gets or sets the threshold value used to determine which pixels are edge pixels.

Syntax

Objective-C

C++/CLI

Java

Python

public int Threshold { get; set; }

@property (nonatomic, assign) NSInteger threshold;

public int getThreshold(); 
public void setThreshold( 
   int intValue 
);

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

Threshold # get and set (EdgeDetectStatisticalCommand)

Property Value

Threshold value used to determine which pixels are edge pixels. If the difference determined by the edge detector algorithm for a pixel is greater than this value, the pixel is an edge pixel. This property only accepts positive values.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void EdgeDetectStatisticalCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\NaturalFruits.jpg")); 
 
   // Prepare the command 
   EdgeDetectStatisticalCommand command = new EdgeDetectStatisticalCommand(); 
   command.Dimension = 15; 
   command.Threshold = 128; 
   command.EdgeColor = new RasterColor(255, 255, 255); 
   command.BackGroundColor = new RasterColor(0, 0, 0); 
   // Apply an edge detector statistical command. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
