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