Property Value

"Percentage" value that indicates whether the pixels that are replaced are lightened or darkened. If this value is greater than 100, the replaced pixels will be lightened. If this value is less than 100, the replaced pixels will be darkened. This method preserves the lightness of the original pixels and substitutes the red color with the new color.

Example

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); 
 
}
