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

'Declaration

Public Class RemoveRedEyeCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As RemoveRedEyeCommand

public sealed class RemoveRedEyeCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Color.RemoveRedEyeCommand()

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

This command has no effect on grayscale images, since there is no "red eye" problem in grayscale images.
To use this command the user should select a small region around the eye. Otherwise, the method will change all the red color in the image. This method also allows the user to replace the red color with a new color for the eyes that is nearest to the original color.
This command 48 and 64-bit color images. Support for 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.
