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

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

'Usage
 
Dim instance As RevEffectCommand

public sealed class RevEffectCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.RevEffectCommand()

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

This command adds a pseudo-3D wave effect to the image . It is similar to the Rutt-Etra Video Synthesizer. The Rutt-Etra video synthesizer was a processor that modulated the deflection lines of a television image so that they appeared to adopt the contours of objects. It was invented by Steve Rutt and Bill Etra in the 1970s.
With this command, you set the maximum height to be used for the pixels with the maximum brightness value. The other pixel heights are calculated by linear interpolation. Each line is 1 pixel in width. Control the spacing between the lines that are drawn across the image with the LineSpace parameter.
You can get a more stable wave by performing the following:
1. Apply any type of blur like Leadtools.ImageProcessing.Effects.GaussianCommand blur with a large radius value.
2. Apply the RevEffectCommand and pass a small value for the maximum height.
3. This command does not support 32-bit grayscale images.
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.
