Syntax

Visual Basic (Declaration)  
Public Class ZoomBlurCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code

public ref class ZoomBlurCommand : public RasterCommand, IRasterCommand 

Example

Run the ZoomBlurCommand on an image.

Visual Basic Copy Code
Public Sub ZoomBlurCommandExample()
   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 ZoomBlurCommand = New ZoomBlurCommand
   command.CenterPoint = New Point(leadImage.Width \ 2, leadImage.Height \ 2)
   command.Dimension = 50
   command.Stress = 5
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void ZoomBlurCommandExample() 
{ 
   // 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 
   ZoomBlurCommand command = new ZoomBlurCommand(); 
   command.CenterPoint     = new Point((image.Width / 2), (image.Height / 2)); 
   command.Dimension       = 50; 
   command.Stress          = 5; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • The command will blur and zoom the image around the specified center point. The center point must be defined inside the image, or inside the region if the image has a region.
  • If the image has a region, the effect will be applied on the region only.
  • 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 signed data images.
  • This command does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this method.
