mediaLib Library Functions                mlib_ImageInvert(3MLIB)



NAME
     mlib_ImageInvert - invert

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

     mlib_status mlib_ImageInvert(mlib_image *dst, const mlib_image *src);


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


     It uses the following equation:

       dst[x][y][i] = (Gwhite + Gblack) - src[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:

     dst    Pointer to destination image.


     src    Pointer to source image.
