NAME
     mlib_ImageConstDiv - division into a constant

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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, respectively.

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]  con-
            tains the constant for channel i.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
