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.
