mlib_ImageSqrShift - square with shifting
cc [ flag... ] file... –lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageSqrShift(mlib_image *dst, const mlib_image *src,
mlib_s32 shift);
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)
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
Right shifting factor. 0 ≤ shift ≤ 31.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
