Syntax

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

public class PunchCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class PunchCommand : public RasterCommand, IRasterCommand 

Example

Run the PunchCommand on an image.

Visual Basic Copy Code
Public Sub PunchCommandExample()
   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 PunchCommand = New PunchCommand
   command.CenterPoint = New Point(leadImage.Width \ 2, leadImage.Height \ 2)
   command.Value = 100
   command.Stress = 100
   command.FillColor = New RasterColor(0, 0, 0)
   command.Flags = PunchCommandFlags.Repeat Or PunchCommandFlags.WithoutRotate
   ' punch 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 PunchCommandExample() 
{ 
   // 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 
   PunchCommand command = new PunchCommand(); 
   command.CenterPoint = new Point((image.Width / 2), (image.Height / 2)); 
   command.Value       = 100; 
   command.Stress      = 100; 
   command.FillColor   = new RasterColor(0,0,0); 
   command.Flags       = PunchCommandFlags.Repeat | PunchCommandFlags.WithoutRotate; 
   // punch the image. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • This command will punch or pinch the image around the 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.
