mlib_ImageYProj_Fp(3MLIB)				    mediaLib Library Functions					 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.

NAME

       mlib_ImageXProj_Fp - image X projection

SYNOPSIS

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

       mlib_status mlib_ImageXProj_Fp(mlib_d64 *xproj, const mlib_image *img);

DESCRIPTION

       The mlib_ImageXProj_Fp() function computes the sum of the pixels in each column of the floating-point 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.
