Summary
Initializes a new EdgeDetectorCommand class object with explicit parameters.
Syntax
C#
Objective-C
C++/CLI
Java
Python
- (instancetype)initWithThreshold:(NSInteger)threshold filter:(LTEdgeDetectorCommandType)filter NS_DESIGNATED_INITIALIZER; 
public EdgeDetectorCommand( 
   int threshold, 
   EdgeDetectorCommandType filter 
); 
public: 
EdgeDetectorCommand(  
   int threshold, 
   EdgeDetectorCommandType filter 
) 
__init__(self,threshold,filter) # Overloaded constructor 

Parameters

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

filter
Flag that indicates which edge detection filter to apply.

Example

Run the EdgeDetectorCommand on an image.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void EdgeDetectorConstructorExample() 
{ 
   // 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 
   EdgeDetectorCommand command = new EdgeDetectorCommand(60, EdgeDetectorCommandType.Laplace2); 
   // find the edges of the image. 
   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"; 
}
