IntensityDetectCommandFlags Enumeration

Summary

Flag that indicates the channel to process. This flag has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Syntax

[FlagsAttribute()] 
public enum IntensityDetectCommandFlags

<FlagsAttribute()> 
Public Enum IntensityDetectCommandFlags

[FlagsAttribute()]

public enum IntensityDetectCommandFlags

Leadtools.ImageProcessing.Color.IntensityDetectCommandFlags = function() { }; 
Leadtools.ImageProcessing.Color.IntensityDetectCommandFlags.prototype = {<br/> 
  Master = 0x00000000, 
    Red = 0x00000001, 
    Green = 0x00000010, 
    Blue = 0x00000100,

[FlagsAttribute()] 
public enum class IntensityDetectCommandFlags

Members

Value	Member	Description
0x00000000	Master	Grayscale Channel.
0x00000001	Red	Red Channel.
0x00000010	Green	Green Channel.
0x00000100	Blue	Blue Channel.

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))
