RemoveRedEyeCommand Constructor(RasterColor,Int32,Int32)

Summary

Initializes a new RemoveRedEyeCommand class object with explicit parameters.

Syntax

WinRT C#

C++

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

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

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

function RemoveRedEyeCommand(  
   newColor , 
   threshold , 
   lightness  
)

public: 
RemoveRedEyeCommand(  
   Leadtools.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.
