GlowCommand Constructor(Int32,Int32,Int32)

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.
Initializes a new GlowCommand class object with explicit parameters.

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

Example

Run the Leadtools.ImageProcessing.SpecialEffects.GlowCommand on an image.

Visual BasicCopy Code
Public Sub GlowConstructorExample()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' 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

public void GlowConstructorExample()
   {
      // Load an image
      RasterCodecs codecs = new RasterCodecs();
      codecs.ThrowExceptionsOnInvalidImages = true;

      RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"));

      // 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);

   }

{
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
}
