mediaLib Library Functions             mlibImageErode4Fp(3MLIB)



NAME
     mlibImageErode4Fp - four neighbor erode

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

     mlibstatus mlibImageErode4Fp(mlibimage *dst, const mlibimage *src);


DESCRIPTION
     The mlibImageErode4Fp() function performs an erode  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 of the images can be
     MLIBFLOAT or MLIBDOUBLE.


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

       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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
