| 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. |
