As far as I can see in PdfContentStreamProcessor.populateOperators(), no handlers for drawing commands are defined yet. Currently, therefore, you wont get those pdf paths. It is easy, though, to expand the parsing package to also forward drawing commands by adding handlers in this method and using extended listeners. You should be aware, though, that all you'll get then are just individual paths. You yourself will have to detect which paths belong to the same image (and which text strings, too! Have a look at your own sample document...), which paths are merely lines separating rows and columns of a table, which paths are merely decorations (perhaps between page text and footer), and which paths are marks e.g. for printers.
