NAME
       mlib_ImageXProj - image X projection

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

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

DESCRIPTION
       The mlib_ImageXProj() function computes the sum of the pixels 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.
