cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageYProj(mlib_d64 *yproj, const mlib_image *img);
The mlib_ImageYProj() function computes the sum of the pixels in each row of the source image.
The image must be a single-channel image.
It uses the following equation:
w-1 yproj[y] = SUM img[x][y][0] x=0
where y = 0, 1, ..., h - 1.
The function takes the following arguments:
Pointer to Y-projection vector, where length is equal to the number of rows in the source image (in other words, the image height).
Pointer to an input image.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
