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.
