SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageMulShift_Inp(mlib_image *src1dst, const mlib_image *src2,
mlib_s32 shift);
DESCRIPTION
The mlib_ImageMulShift_Inp() function multiplies the pixel values of
the two source images in place. 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:
src1dst[x][y][i] = src1dst[x][y][i] * src2[x][y][i] * 2**(-shift)
PARAMETERS
The function takes the following arguments:
src1dst Pointer to source and destination 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.
