mediaLib Library Functions              mlibImageConstDiv(3MLIB)



NAME
     mlibImageConstDiv - division into a constant

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

     mlibstatus mlibImageConstDiv(mlibimage *dst, const mlibimage *src,
          const mlibd64 *c);


DESCRIPTION
     The mlibImageConstDiv() 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] = DATATYPEMAX  if c[i] > 0
       dst[x][y][i] = DATATYPEMIN  if c[i] < 0



     where DATATYPE is MLIBU8, MLIBS16, MLIBU16, or  MLIBS32
     for  an image of type MLIBYTE, MLIBSHORT, MLIBUSHORT, or
     MLIBINT, 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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
