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.
