GlowCommand Constructor(int,int,int)

Summary

Initializes a new GlowCommand class object with explicit parameters.

Syntax

WinRT C#

C++

public GlowCommand( 
   int dimension, 
   int brightness, 
   int threshold 
)

  
Public Function New( _ 
   ByVal dimension As Integer, _ 
   ByVal brightness As Integer, _ 
   ByVal threshold As Integer _ 
)

public GlowCommand(  
   int dimension, 
   int brightness, 
   int threshold 
)

function GlowCommand(  
   dimension , 
   brightness , 
   threshold  
)

public: 
GlowCommand(  
   int dimension, 
   int brightness, 
   int threshold 
)

Parameters

dimension
Size of the neighborhood used to determine the width of the glow. This parameter only accepts positive values.

brightness
Brightness factor used to create the "glow". This can be any number that is 0 or greater. If it is 0 the image will be black.

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. Valid values range from 0 through 255. Use this parameter to control the number of edge pixels found.

Example

Run the GlowCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void GlowConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   GlowCommand command = new GlowCommand(5, 3, 2); 
   // Apply glow effect on 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:\Users\Public\Documents\LEADTOOLS Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.SpecialEffects 
      Leadtools.Examples.Support.SetLicense() 
 
Public Sub GlowConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")) 
 
   ' Prepare the command 
   Dim command As GlowCommand = New GlowCommand(5, 3, 0) 
   ' Apply glow effect on the image. 
   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:\Users\Public\Documents\LEADTOOLS Images" 
End Class
