I'm not sure about end-user packages, but I work with some
OCR libraries that do barcode decoding as well. For that
matter, I've written a Code128 decoder at work. Once you
know how wide the spaces and bars are, the decoding is
pretty easy. Determining those widths turns out to be
trickier than you'd expect.
