NAME
     mlib_ImageDilate4 - four neighbor dilate

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_ImageDilate4(mlib_image *dst, const mlib_image *src);


DESCRIPTION
     The mlib_ImageDilate4() function performs a dilation  opera-
     tion  on  an  image  by  using  each pixel's four orthogonal
     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 4-neighbor binary images, it uses  the  following  equa-
     tion:

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



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

       dst[x][y][0] = MAX{ 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.
