mlib_ImageDilate4 - four neighbor dilate SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDilate4(mlib_image *dst, const mlib_image *src); DESCRIPTION
The mlib_ImageDilate4() function performs a dilation operation on an image by using each pixel's four orthogonal 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 4-neighbor binary images, it uses the following equation: dst[x][y][0] = OR{ src[x][y][0], src[x-1][y][0], src[x+1][y][0], src[x][y-1][0], src[x][y+1][0] } For 4-neighbor grayscale images, it uses the following equation: dst[x][y][0] = MAX{ 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 MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
