16 The mlib_ImageXProj_Fp() function computes the sum of the pixels in
17 each column 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 h-1
26 xproj[x] = SUM img[x][y][0]
27 y=0
28
29
30
31 where x = 0, 1, ..., w - 1.
32
34 The function takes the following arguments:
35
36 xproj Pointer to X-projection vector, where length is equal to the
37 number of columns in the source image (in other words, the
38 image width).
39
40
41 img Pointer to an input image.
42
43
45 The function returns MLIB_SUCCESS if successful. Otherwise it returns
46 MLIB_FAILURE.
