NAME

6       mlib_ImageSqrShift - square with shifting
7

SYNOPSIS

9       cc [ flag... ] file... -lmlib [ library... ]
10       #include <mlib.h>
11
12       mlib_status mlib_ImageSqrShift(mlib_image *dst, const mlib_image *src,
13            mlib_s32 shift);

DESCRIPTION

17       The  mlib_ImageSqrShift() function computes the square of each pixel in
18       the source image and scales the result by the shift factor.
19
20
21       It uses the following equation:
22
23         dst[x][y][i] = src[x][y][i] * src[x][y][i] * 2**(-shift)

25

PARAMETERS

27       The function takes the following arguments:
28
29       dst      Pointer to destination image.
30
31
32       src      Pointer to source image.
33
34
35       shift    Right shifting factor. 0 ≤ shift ≤ 31.

37

RETURN VALUES

39       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
40       MLIB_FAILURE.
