Members

Value	Member	Description
0x00000000	LowHighBits	Use only the bits between the LowBit and HighBit values.
0x00000000	Master	All channels. 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))
0x00000001	Red	Red channel only.
0x00000002	Green	Green channel only.
0x00000003	Blue	Blue channel only.
0x00000010	AllBits	Use all the bits for calculating the histogram (the LowBit and HighBit values are ignored.)
0x00000100	Force256	Force the resulted histogram array to 256 entries length.
