mlib_ImageDilate8(3MLIB)				    mediaLib Library Functions					  mlib_ImageDilate8(3MLIB)

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.

NAME

       mlib_ImageConstDiv - division into a constant

SYNOPSIS

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

       mlib_status mlib_ImageConstDiv(mlib_image *dst, const mlib_image *src, const mlib_d64 *c);

DESCRIPTION

       The mlib_ImageConstDiv() function divides each pixel in an image into a constant value on a pixel-by-pixel basis.

       It uses the following equation:

       dst[x][y][i] = c[i] / src[x][y][i]

       In the case of src[x][y][i] = 0,

       dst[x][y][i] = 0 	     if c[i] = 0
       dst[x][y][i] = DATA_TYPE_MAX  if c[i] > 0
       dst[x][y][i] = DATA_TYPE_MIN  if c[i] < 0

       where  DATA_TYPE  is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT, respec-
       tively.

PARAMETERS

       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       c	       Constant into which each pixel is divided. c[i] contains the constant for channel i.

RETURN VALUES

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