public class FreeHandWaveCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

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

'Usage
 
Dim instance As FreeHandWaveCommand

public sealed class FreeHandWaveCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.FreeHandWaveCommand()

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

The command applies the wave in the amplitudes array. You can repeat and rotate the wave in any direction. The amplitudes data can be obtained from the Leadtools.ImageProcessing.Effects.EffectsUtilities.GetCurvePoints(System.Int32[],Leadtools.LeadPoint[],Leadtools.ImageProcessing.Effects.CurvePointsType) utility method.
If the image has a region, the effect will be applied on the region only.
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.

For more information, refer to Applying Artistic Effects.

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