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.
