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

'Usage
 
Dim instance As FreeRadialBendCommand

public sealed class FreeRadialBendCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.FreeRadialBendCommand()

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

If the image has a region, the effect will be applied on the region only.
For an example, the following figure shows a image before the effect is applied.
The following figure shows the same image after the effect has been applied.
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.
