Syntax

Objective-C

C++/CLI

Java

Python

public int Level { get; set; }

@property (nonatomic, assign) NSUInteger level;

public int getLevel(); 
public void setLevel( 
   int intValue 
);

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

Level # get and set (EdgeDetectEffectCommand)

Property Value

Level value used to determine the brightness of the edges. Standard value is 50. Range is between 1 and 100. Big values will produce bright edges.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void EdgeDetectEffectCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   EdgeDetectEffectCommand command = new EdgeDetectEffectCommand(); 
   command.Level = 50; 
   command.Threshold = 0; 
   command.Type = EdgeDetectEffectCommandType.Smooth; 
   // Apply find edges effect on the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
