NAME
     mlibImageSqrShiftInp - square with shifting, in place

SYNOPSIS

     #include 

     mlibstatus mlibImageSqrShiftInp(mlibimage *srcdst, mlibs32 shift);


DESCRIPTION

     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

     srcdst    Pointer to source and destination image.


     shift     Right shifting factor. 0 < shift < 31.


RETURN VALUES

     it returns MLIBFAILURE.
