NAME
       mlib_ImageSqrShift_Inp - square with shifting, in place

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

       mlib_status mlib_ImageSqrShift_Inp(mlib_image *srcdst, mlib_s32 shift);

DESCRIPTION
       The  mlib_ImageSqrShift_Inp()  function computes the square of each pixel in the source image and scales the result by the shift factor, in
       place.

       It uses the following equation:

	 srcdst[x][y][i] = srcdst[x][y][i] * srcdst[x][y][i] * 2**(-shift)

PARAMETERS
       The function takes the following arguments:

       srcdst	 Pointer to source and destination image.

       shift	 Right shifting factor. 0 <= shift <= 31.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
