NAME
mlib_ImageSqrShift_Inp - square with shifting, in place
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
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.
