Leadtools.ImageProcessing.SpecialEffects Namespace : FragmentCommand Class



Averages an image with its shifted copies. This method is available in the Raster Pro and above toolkits. This method creates four copies of an image. Each copy is shifted by the offset amount into one of the four directions: top, left, bottom and right. Then the image is averaged with its shifted copies.

Object Model

FragmentCommand Class

Syntax

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

Example

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

Visual BasicCopy Code
Public Sub FragmentCommandExample()
   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 FragmentCommand = New FragmentCommand
   command.Offset = 4
   command.Opacity = 75
   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
C#Copy Code
public void FragmentCommandExample()
   {
      // Load an image
      RasterCodecs codecs = new RasterCodecs();
      codecs.ThrowExceptionsOnInvalidImages = true;

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

      // Prepare the command
      FragmentCommand command  = new FragmentCommand();
      command.Offset    = 4;
      command.Opacity   = 75;
      command.Run(image);
      codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);

   }

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

Remarks

  • This method can process the whole image or a region of the image. If the image has a region, the effect is applied only to the region.
  • 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.
