It uses the following equation:

dst[x][y][0] = weight[0]*src[x][y][0] +
              weight[1]*src[x][y][1] +
              weight[2]*src[x][y][2]

 

PARAMETERS

The function takes the following arguments:

dst

Pointer to destination image.

src

Pointer to source image.

weight

Array of three blending coefficients. It is recommended that these sum to 1.0, but it is not required.
