NAME

6       mlib_ImageYProj_Fp - image Y projection
7

SYNOPSIS

9       cc [ flag... ] file... -lmlib [ library... ]
10       #include <mlib.h>
11
12       mlib_status mlib_ImageYProj_Fp(mlib_d64 *yproj, const mlib_image *img);

DESCRIPTION

16       The  mlib_ImageYProj_Fp()  function  computes  the sum of the pixels in
17       each row of the floating-point source image.
18
19
20       The image must be a single-channel image.
21
22
23       It uses the following equation:
24
25                    w-1
26         yproj[y] = SUM img[x][y][0]
27                    x=0
28
29
30
31       where y = 0, 1, ..., h - 1.
32

PARAMETERS

34       The function takes the following arguments:
35
36       yproj    Pointer to Y-projection vector, where length is equal  to  the
37                number  of rows in the source image (in other words, the image
38                height).
39
40
41       img      Pointer to an input image.
42
43

RETURN VALUES

45       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
46       MLIB_FAILURE.
