NAME
mlib_ImageInvert_Inp - invert in place
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> 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_ImageIn- vert_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.
