FreeHandWaveCommand Class

Summary

Distorts the image by the wave specified in the amplitudes array and the rotation angle. This command is available in the Imaging Pro and above toolkits.

Syntax

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

Remarks

For more information, refer to Applying Artistic Effects.

Example

Run the FreeHandWaveCommand on an image and apply triangular wave on the loaded image.
