mediaLib Library Functions mlib_ImageMulShift(3MLIB)
NAME
mlib_ImageMulShift - multiplication
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
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 imageon 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.
