A subtree is ``(label, target, children, state)``. ``label`` is a string, ``target`` is ``(page_number, x, y)`` and ``children`` is a list of child subtrees. r)r4r5fr3) enumeraterrr*r) r1r9transform_pagesrootskipped_levels last_by_depthprevious_level page_numberpagematrixr r r!make_bookmark_trees zDocument.make_bookmark_treeNcKs(t}|||}|d}r3t|\}}d|vr%|ds%|d|d<d|vr3|ds3|d|d<t|||fi|} |rD||| |d} |d } |d} |duret} | | | | | | St |drt| || | | dSt |d }| || | | WddS1swYdS) aPaint the pages in a PDF file, with metadata. :type target: :class:`str`, :class:`pathlib.Path` or :term:`file object` :param target: A filename where the PDF file is generated, a file object, or :obj:`None`. :param float zoom: The zoom factor in PDF units per CSS units. **Warning**: All CSS units are affected, including physical units like ``cm`` and named sizes like ``A4``. For values other than 1, the physical CSS units will thus be "wrong". :type finisher: :term:`callable` :param finisher: A finisher function or callable that accepts the document and a :class:`pydyf.PDF` object as parameters.
