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.

Syntax

Visual Basic (Declaration)  
Public Function New( _
   ByVal dimension As Integer, _
   ByVal brightness As Integer, _
   ByVal threshold As Integer _
)
Visual Basic (Usage) Copy Code
Dim dimension As Integer
Dim brightness As Integer
Dim threshold As Integer
 
Dim instance As GlowCommand(dimension, brightness, threshold)
C#  
public GlowCommand( 
   int dimension,
   int brightness,
   int threshold
)
C++/CLI  
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.

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

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "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, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void GlowConstructorExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   GlowCommand command = new GlowCommand(5, 3, 2); 
   // Apply glow effect on the image. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}
