NAME
     mlibImageSqrShift - square with shifting

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibImageSqrShift(mlibimage *dst, const mlibimage *src,
          mlibs32 shift);


DESCRIPTION
     The mlibImageSqrShift() 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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
