- 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.
