Warps the active image along a curved plane, centered on the pivot point. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the BendCommand on an image.

Visual Basic Copy Code
Public Sub BendCommandExample()
   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 BendCommand = New BendCommand
   command.Value = 100
   ' bend the image around it is center.
   command.CenterPoint = New Point(leadImage.Width \ 2, leadImage.Height \ 2)
   command.Flags = BendCommandFlags.Repeat Or BendCommandFlags.WithoutRotate Or BendCommandFlags.Normal
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void BendCommandExample() 
{ 
   // 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 
   BendCommand command = new BendCommand(); 
   command.Value         = 100; 
   // bend the image around it is center. 
   command.CenterPoint   = new System.Drawing.Point(image.Width  / 2, image.Height / 2); 
   command.Flags         = BendCommandFlags.Repeat | BendCommandFlags.WithoutRotate | BendCommandFlags.Normal; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • The command bends the image around the specified CenterPoint. 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.
