mlib_status mlib_ImageMulShift(mlib_image *dst, const mlib_image *src1,
const mlib_image *src2, mlib_s32 shift);
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)
The function takes the following arguments:
Pointer to destination image.
Pointer to first source image.
Pointer to second source image.
Right shifting factor. 0 ≤ shift ≤ 31.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
