NAME
       mlib_ImageConstDiv_Inp - division into a constant

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

       mlib_status mlib_ImageConstDiv_Inp(mlib_image *srcdst, const mlib_d64 *c);

DESCRIPTION
       The mlib_ImageConstDiv_Inp() function divides each pixel in an image by a constant value on a pixel-by-pixel basis, in place.

       It uses the following equation:

       srcdst[x][y][i] = c[i] / srcdst[x][y][i]

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

       srcdst[x][y][i] = 0		if c[i] = 0
       srcdst[x][y][i] = DATA_TYPE_MAX	if c[i] > 0
       srcdst[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:

       srcdst	       Pointer to source and destination 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.
