Visual Basic (Declaration)  
Public Class DiffuseGlowCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As DiffuseGlowCommand
C#  
public class DiffuseGlowCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class DiffuseGlowCommand : public RasterCommand, IRasterCommand 

Example

Run the DiffuseGlowCommand on an image and applies the Diffuse Glow filter.

Visual Basic Copy Code
Public Sub DiffuseGlowCommandExample()
   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 fillColor As New RasterColor(255, 255, 255)
   Dim command As New DiffuseGlowCommand
   command.GlowAmount = 50
   command.ClearAmount = 50
   command.SpreadAmount = 10
   command.WhiteNoiseRange = 10
   command.GlowColor = fillColor
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void DiffuseGlowCommandExample() 
{ 
   // 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 
   RasterColor fillColor = new RasterColor(255, 255, 255); 
   DiffuseGlowCommand command = new DiffuseGlowCommand () ; 
   command.GlowAmount = 50; 
   command.ClearAmount = 50; 
   command.SpreadAmount = 10; 
   command.WhiteNoiseRange = 10; 
   command.GlowColor = fillColor; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • This command adds pixels randomly to the image. A glow is added based on a combination of the pixel colors and the glow color.
  • As an example, if you use the following image:

    And you were to call DiffuseGlowCommand using the following settings:
    Parameter Value
    GlowAmount 50
    ClearAmount 50
    SpreadAmount 10
    WhiteNoiseRange 10
    GlowColor white

    The following figure results:
  • If the image has a region, the effect will be applied on the region only.
  • This method supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
  • This method does not support signed data images.
  • This command does not support 32-bit grayscale images.
