mlib_ImageMulShift(3MLIB)				    mediaLib Library Functions					 mlib_ImageMulShift(3MLIB)

NAME
       mlib_ImageMulShift - multiplication

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.
