public class BendCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class BendCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As BendCommand

public sealed class BendCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.BendCommand()

public ref class BendCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

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.
