Leadtools.ImageProcessing.SpecialEffects Namespace : FreeRadialBendCommand Class



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

Syntax

Visual Basic (Declaration)  
Public Class FreeRadialBendCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code

Remarks

  • 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.
