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

C#
VB
WinRT C#
C++
public class FreeRadialBendCommand : RasterCommand 
public sealed class FreeRadialBendCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand   
function Leadtools.ImageProcessing.SpecialEffects.FreeRadialBendCommand() 

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.
