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-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit 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.

Example

Run the PunchCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void PunchCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   PunchCommand command = new PunchCommand(); 
   command.CenterPoint = new LeadPoint((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, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
} 
Imports Leadtools

Imports Leadtools.ImageProcessing.SpecialEffects 
 
Public Sub PunchCommandExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")) 
 
   ' Prepare the command 
   Dim command As PunchCommand = New PunchCommand 
   command.CenterPoint = New LeadPoint(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, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub
