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#

C++/CLI

Python

public class FreeHandWaveCommand : RasterCommand

public ref class FreeHandWaveCommand : public RasterCommand

class FreeHandWaveCommand(RasterCommand):

Remarks

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-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.

Example

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

C#

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects;

   command.Flags = FreeHandWaveCommandFlags.Repeat | FreeHandWaveCommandFlags.Frequency; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
