SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
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.
