NAME
       mlib_ImageErode4_Fp - four neighbor erode

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

       mlib_status mlib_ImageErode4_Fp(mlib_image *dst, const mlib_image *src);

DESCRIPTION
       The  mlib_ImageErode4_Fp() function performs an erode operation on an image by using each pixel's four orthogonal neighbors. The source and
       destination images must be single-channel images. The data type of the images can be MLIB_FLOAT or MLIB_DOUBLE.

       For 4-neighbor grayscale images, it uses the following equation:

	 dst[x][y][0] = MIN{ src[x][y][0],
			     src[x-1][y][0], src[x+1][y][0],
			     src[x][y-1][0], src[x][y+1][0] }

       where x = 1, ..., w-2; y = 1, ..., h-2.

PARAMETERS
       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

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