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.
