cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageXProj(mlib_d64 *xproj, const mlib_image *img);
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
The function takes the following arguments:
xproj
img
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
