Flags Property

Summary

Flags that indicate the channel that will be used, the treatment of the input pixel values, the mathematical operation, and the treatment of the output pixel values.

Property Value

Flags that indicate the channel that will be used, the treatment of the input pixel values, the mathematical operation, and the treatment of the output pixel values. Use a bitwise OR ( ¦ ) to specify one flag from each group.

Remarks

Calculating Master Channel Values

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))
