NAME
     mlibImageXProj - image X projection

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

     mlibstatus mlibImageXProj(mlibd64 *xproj, const mlibimage *img);


DESCRIPTION
     The mlibImageXProj() function computes the sum of the  pix-
     els in each column of the source image.


     The image must be a single-channel image.


     It uses the following equation:

                  h-1
       xproj[x] = SUM img[x][y][0]
                  y=0



     where x = 0, 1, ..., w - 1.

PARAMETERS
     The function takes the following arguments:

     xproj    Pointer to X-projection  vector,  where  length  is
              equal  to the number of columns in the source image
              (in other words, the image width).


     img      Pointer to an input image.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
