mlib_status mlib_ImageMulShift(mlib_image *dst, const mlib_image *src1,
    const mlib_image *src2, mlib_s32 shift);

 

DESCRIPTION

The mlib_ImageMulShift() function multiplies the pixel values of the two source images. It scales the result by a right shift and writes the result to the destination image on a pixel-by-pixel basis.

It uses the following equation:

dst[x][y][i] = src1[x][y][i] * src2[x][y][i] * 2**(-shift)

 

PARAMETERS

The function takes the following arguments:

dst

Pointer to destination image.

src1

Pointer to first source image.

src2

Pointer to second source image.

shift

Right shifting factor. 0 ≤ shift ≤ 31.

 

RETURN VALUES

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
