FreeRadialBendCommand Class

Summary

Wraps the image along its radius on a 3D surface shaped by Curve. This command is available in the Imaging Pro and above toolkits.

Syntax

WinRT C#

C++

public class FreeRadialBendCommand : RasterCommand

  
Public Class FreeRadialBendCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class FreeRadialBendCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.FreeRadialBendCommand()

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

Remarks

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

The following figure shows the same image after the effect has been applied.
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.

For more information, refer to Correcting Colors.

Example

Run the FreeRadialBendCommand on an image.
