mlib_ImageInvert_Fp_Inp(3MLIB)				    mediaLib Library Functions				    mlib_ImageInvert_Fp_Inp(3MLIB)

NAME

       mlib_ImageInvert_Fp_Inp - invert

SYNOPSIS

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

       mlib_status mlib_ImageInvert_Fp_Inp(mlib_image *srcdst);

DESCRIPTION

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

       It uses the following equation:

       srcdst[x][y][i] = -srcdst[x][y][i]

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.

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.
