NAME
       mlib_ImageInvert - invert

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

       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_ImageIn-
       vert_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.

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