EdgeDetectStatisticalCommand Constructor(int,int,RasterColor,RasterColor)

Summary

Initializes a new EdgeDetectStatisticalCommand class object with explicit parameters.

Syntax

Objective-C

C++

Java

public EdgeDetectStatisticalCommand( 
   int dimension, 
   int threshold, 
   RasterColor edgeColor, 
   RasterColor backGroundColor 
)

Public Function New( _ 
   ByVal dimension As Integer, _ 
   ByVal threshold As Integer, _ 
   ByVal edgeColor As RasterColor, _ 
   ByVal backGroundColor As RasterColor _ 
)

- (instancetype)initWithDimension:(NSUInteger)dimension 
                        threshold:(NSInteger)threshold 
                        edgeColor:(LTRasterColor*)edgeColor 
                  backgroundColor:(LTRasterColor *)backgroundColor

public EdgeDetectStatisticalCommand( 
   int dimension,  
   int threshold,  
   RasterColor edgeColor,  
   RasterColor backGroundColor 
)

public: 
EdgeDetectStatisticalCommand(  
   int dimension, 
   int threshold, 
   RasterColor edgeColor, 
   RasterColor backGroundColor 
)

Parameters

dimension
Dimensions of the neighborhood used to detect edges (Dimension x Dimension), in pixels. This parameter only accepts positive values.

threshold
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 parameter only accepts positive values.

edgeColor
Edge color.

backGroundColor
Non edge color.

Example

Run the EdgeDetectStatisticalCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void EdgeDetectStatisticalConstructorExample() 
{ 
   // 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(5, 100, new RasterColor(255, 255, 255), 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:\LEADTOOLS21\Resources\Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Effects 
 
Public Sub EdgeDetectStatisticalConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\NaturalFruits.jpg")) 
 
   ' Prepare the command 
   Dim command As EdgeDetectStatisticalCommand 
   command = New EdgeDetectStatisticalCommand(5, 100, New RasterColor(255, 255, 255), New RasterColor(0, 0, 0)) 
   ' Apply an edge detector statistical command. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\LEADTOOLS21\Resources\Images"
