Remarks

This command will shear the image using the wave in the amplitudes array. The wave can be applied vertically or horizontally. The amplitude data can be obtained from the Leadtools.ImageProcessing.Effects.EffectsUtilities.GetCurvePoints utility method.
This command does not support signed data images.
