Summary

Initializes a new GrayScaleExtendedCommand class object with explicit parameters.

Syntax
C#
VB
Java
Objective-C
C++
Public Function New( _ 
   ByVal redFactor As Integer, _ 
   ByVal greenFactor As Integer, _ 
   ByVal blueFactor As Integer _ 
) 
- (instancetype)initWithRedFactor:(NSInteger)redFactor 
                      greenFactor:(NSInteger)greenFactor 
                       blueFactor:(NSInteger)blueFactor 
public GrayScaleExtendedCommand( 
   int redFactor,  
   int greenFactor,  
   int blueFactor 
) 
public: 
GrayScaleExtendedCommand(  
   int redFactor, 
   int greenFactor, 
   int blueFactor 
) 

Parameters

redFactor
Value that represents the percentage or weight given to the red value of each pixel in the image. Possible values are 0 to 1000.

greenFactor
Value that represents the percentage or weight given to the green value of each pixel in the image. Possible values are 0 to 1000.

blueFactor
Value that represents the percentage or weight given to the blue value of each pixel in the image. Possible values are 0 to 1000.

Example

Run the GrayScaleExtendedCommand on an image with RedFactor = 300, GreenFactor = 590, and BlueFactor = 110.
