RemoveRedEyeCommand Class

Summary

Removes the "red eye" effect in color images by converting the red color in the eye to a new color.

Syntax

WinRT C#

C++

public class RemoveRedEyeCommand : RasterCommand

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

public sealed class RemoveRedEyeCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Color.RemoveRedEyeCommand()

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

Remarks

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.

Example

Run the RemoveRedEyeCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void RemoveRedEyeCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "red_eye.cmp")); 
 
   // Prepare the command 
   RemoveRedEyeCommand command = new RemoveRedEyeCommand(); 
   //Apply the redeye removal command. 
   command.NewColor = new RasterColor(5, 20, 10); 
   command.Threshold = 125; 
   command.Lightness = 100; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
