This flag has a FlagsAttribute attribute that allows a bitwise combination of its member values.
[FlagsAttribute()] public enum IntensityDetectCommandFlags : System.Enum, System.IComparable, System.IConvertible, System.IFormattable
'Declaration
<FlagsAttribute()> Public Enum IntensityDetectCommandFlags Inherits System.Enum Implements System.IComparable, System.IConvertible, System.IFormattable
'Usage
Dim instance As IntensityDetectCommandFlags
[FlagsAttribute()] public enum IntensityDetectCommandFlags : System.IComparable, System.IConvertible, System.IFormattable
typedef NS_OPTIONS(NSUInteger, LTIntensityDetectCommandFlags)
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 : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable
Value | Member | Description |
---|---|---|
0x00000000 | Master | Grayscale Channel. |
0x00000001 | Red | Red Channel. |
0x00000010 | Green | Green Channel. |
0x00000100 | Blue | Blue Channel. |
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))
