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.
