RemoveRedEyeCommand Class

Summary

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

Syntax

C#
VB
WinRT C#
C++
public class RemoveRedEyeCommand : RasterCommand 
function Leadtools.ImageProcessing.Color.RemoveRedEyeCommand() 

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.

   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); 
 
}
