mediaLib Library Functions            mlib_ImageInvert_Inp(3MLIB)



NAME
     mlib_ImageInvert_Inp - invert in place

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

     mlib_status mlib_ImageInvert_Inp(mlib_image *srcdst);


DESCRIPTION
     The mlib_ImageInvert_Inp() function  performs  the  in-place
     inversion  of  an image such that white becomes black, light
     gray becomes dark gray, and so on.


     It uses the following equation:

       srcdst[x][y][i] = (Gwhite + Gblack) - srcdst[x][y][i]



     The values of Gwhite  and  Gblack  for  different  types  of
     images are:



       Image Type         Gwhite          Gblack       Gwhite + Gblack
     _________________________________________________________________
     MLIB_BYTE        255              0               255 (0xFF)
     MLIB_SHORT       32767            -32768          -1 (0xFFFF)
     _________________________________________________________________
     MLIB_USHORT      65535            0               65535 (0xFFFF)
     _________________________________________________________________
     MLIB_INT         2147483647       -2147483648     -1 (0xFFFFFFFF)



     Given  that  integer  data  are  in  the  two's   complement
     representation,    mlib_ImageInvert()   is   the   same   as
     mlib_ImageNot(), while mlib_ImageInvert_Inp() is the same as
     mlib_ImageNot_Inp().

PARAMETERS
     The function takes the following arguments:

     srcdst    Pointer to source and destination image.


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