Leadtools.ImageProcessing.Effects Namespace : GaussianCommand Class



Smooths or blurs an image by applying a Gaussian filter to the specified image.

Syntax

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

Example

Run the GaussianCommand on an image and applies the Gaussian filter.

Visual BasicCopy Code
Public Sub GaussianCommandExample()
   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 GaussianCommand = New GaussianCommand
   command.Radius = 20
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C#Copy Code
public void GaussianCommandExample() 
{ 
   // 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 
   GaussianCommand command = new GaussianCommand(); 
   command.Radius = 20; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • Each pixel in the image is blurred based on neighborhood pixels. The radius value determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.
  • The amount of blur is controlled by specifying the size of the neighborhood used for blurring or smoothing. The value of the Radius property determines the size and values of the mask.
  • This command 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 command does not support 32-bit grayscale images.
