RemoveRedEyeCommand Constructor(RasterColor,int,int)

Summary

Initializes a new RemoveRedEyeCommand class object with explicit parameters.

Syntax

C++

public RemoveRedEyeCommand( 
   RasterColor newColor, 
   int threshold, 
   int lightness 
)

Public Function New( _ 
   ByVal newColor As RasterColor, _ 
   ByVal threshold As Integer, _ 
   ByVal lightness As Integer _ 
)

public: 
RemoveRedEyeCommand(  
   RasterColor newColor, 
   int threshold, 
   int lightness 
)

Parameters

newColor
Contains the new color value used to replace the red color in the eyes.

threshold
Threshold value that indicates which pixels will be changed by this command. All pixels with a red component value greater than this value will be changed. Pixels with a red component value less than this value will not be changed. This value is between 0 and 255.

lightness
"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 command preserves the lightness of the original pixels and substitutes the red color with the new color.

Example

Run the RemoveRedEyeCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void RemoveRedEyeConstructorExample() 
{ 
   // 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(new RasterColor(5, 20, 10), 125, 100); 
   //Apply the redeye removal command. 
   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"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Color 
 
Public Sub RemoveRedEyeConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "red_eye.cmp")) 
 
   ' Prepare the command 
   Dim command As RemoveRedEyeCommand = New RemoveRedEyeCommand(New RasterColor(5, 20, 10), 125, 100) 
   'Apply the redeye removal command. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
