mlib_ImageSqrShift(3MLIB) mediaLib Library Functions mlib_ImageSqrShift(3MLIB)NAMEmlib_ImageSqrShift - square with shifting
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageSqrShift(mlib_image *dst, const mlib_image *src,
mlib_s32 shift);
DESCRIPTION
The mlib_ImageSqrShift() function computes the square of each pixel in
the source image and scales the result by the shift factor.
It uses the following equation:
dst[x][y][i] = src[x][y][i] * src[x][y][i] * 2**(-shift)
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image.
src Pointer to source image.
shift Right shifting factor. 0 ≤ shift ≤ 31.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
