NAME
       mlib_ImageYProj - image Y projection

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageYProj(mlib_d64 *yproj, const mlib_image *img);

DESCRIPTION
       The mlib_ImageYProj() function computes the sum of the pixels 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 MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
