SYNOPSIS

10       #include <mlib.h>

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

DESCRIPTION

17       The  mlib_ImageMulShift()  function  multiplies the pixel values of the
18       two source images. It scales the result by a right shift and writes the
19       result to the destination image on a pixel-by-pixel basis.
20
21
22       It uses the following equation:
23
24         dst[x][y][i] = src1[x][y][i] * src2[x][y][i] * 2**(-shift)

26

PARAMETERS

28       The function takes the following arguments:
29
30       dst      Pointer to destination image.
31
32
33       src1     Pointer to first source image.
34
35
36       src2     Pointer to second source image.
37
38
39       shift    Right shifting factor. 0 ≤ shift ≤ 31.

RETURN VALUES

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