SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageYProj_Fp(mlib_d64 *yproj, const mlib_image *img);
DESCRIPTION
The mlib_ImageYProj_Fp() function computes the sum of the pixels in
each row of the floating-point 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.
