Channel Property

Summary

Gets or sets a value that represents the color plane to which to add the noise.

Syntax

Java

Objective-C

WinRT C#

C++

public RasterColorChannel Channel { get; set; }

Public Property Channel As Leadtools.Imageprocessing.RasterColorChannel

public Leadtools.Imageprocessing.RasterColorChannel Channel {get; set;}

@property (nonatomic, assign) LTRasterColorChannel channel

public RasterColorChannel getChannel() 
public void setChannel(RasterColorChannel value)

 <br/>get_Channel();<br/>set_Channel(value);<br/>Object.defineProperty('Channel');

public: 
property Leadtools.Imageprocessing.RasterColorChannel Channel { 
   Leadtools.Imageprocessing.RasterColorChannel get(); 
   void set (    Leadtools.Imageprocessing.RasterColorChannel ); 
}

Property Value

Color plane constant. This plane will be affected by the noise.

Remarks

In order to speed up widely used image processing filters in LEADTOOLS, the grayscale value (master channel) of a colored image is calculated using the following formulas:

#define CalcGrayValue(r, g, b) ((L_UCHAR)(((L_UCHAR) (((2 * (L_UINT) (r)) + (5 * (L_UINT) (g)) + (L_UINT) (b) + 4) / 8)))) 
#define CalcGrayValue16(r, g, b) ((L_UINT16) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8)) 
#define CalcGrayValue32(r, g, b) ((L_UINT32) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8))
