mlib_ImageYProj_Fp (3MLIB)

Name

mlib_ImageYProj_Fp - image Y projection

Synopsis

cc [ flag... ] file... –lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_ImageYProj_Fp(mlib_d64 *yproj, const mlib_image *img);

Description

The mlib_ImageYProj_Fp() function computes the sum of the pixels in each row of the floating-point 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.

Parameters

The function takes the following arguments:

yproj

Pointer to Y-projection vector, where length is equal to the number of rows in the source image (in other words, the image height).

img

Pointer to an input image.

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
