NAME
     mlibImageYProj - image Y projection

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

     mlibstatus mlibImageYProj(mlibd64 *yproj, const mlibimage *img);


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


     The image must be a single-channel image.


     It uses the following equation:

                  w-1
       yproj[y] = SUM img[x][y][0]
                  x=0



     where y = 0, 1, ..., h - 1.

PARAMETERS
     The function takes the following arguments:

     yproj    Pointer to Y-projection  vector,  where  length  is
              equal to the number of rows in the source image (in
              other words, the image height).


     img      Pointer to an input image.


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