NAME
     mlib_ImageXProj - image X projection

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

     mlib_status mlib_ImageXProj(mlib_d64 *xproj, const mlib_image *img);


DESCRIPTION
     The mlib_ImageXProj() 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 MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
