NAME
       mlib_ImageDilate8 - eight neighbor dilate

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

       mlib_status mlib_ImageDilate8(mlib_image *dst, const mlib_image *src);

DESCRIPTION
       The  mlib_ImageDilate8()  function  performs a dilation operation on an image by using all eight of each pixel's neighbors.  The source and
       destination images must be single-channel images.  The data type can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT.

       For 8-neighbor binary images, it uses the following equation:

       dst[x][y][0] = OR{ src[p][q][0],
			  x-1 <= p <= x+1; y-1 <= q <= y+1 }

       For 8-neighbor grayscale images, it uses the following equation:

       dst[x][y][0] = MAX{ src[p][q][0],
			   x-1 <= p <= x+1; y-1 <= q <= y+1 }

       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.
