NAME
     mlibImageErode8 - eight neighbor erode

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

     mlibstatus mlibImageErode8(mlibimage *dst, const mlibimage *src);


DESCRIPTION
     The mlibImageErode8() function performs an erode  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  MLIBIT,  MLIBYTE,
     MLIBSHORT, MLIBUSHORT, or MLIBINT.


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

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



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

       dst[x][y][0] = MIN{ 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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
