dddZ dS )r a Represents an HTML document parsed by `lxml `_.
You can just create an instance with a positional argument:
``doc = HTML(something)``
The class will try to guess if the input is a filename, an absolute URL,
or a file-like object.
Alternatively, use **one** named argument so that no guessing is involved:
:param filename: A filename, relative to the current directory or absolute.
:param url: An absolute, fully qualified URL.
:param file_obj: a file-like: any object with a :meth:`~file.read` method.
:param string: a string of HTML source. (This argument must be named.)
:param tree: a parsed lxml tree. (This argument must be named.)
Specifying multiple inputs is an error: ``HTML(filename=foo, url=bar)``
will raise.
You can also pass optional named arguments:
:param encoding: Force the source character encoding.
:param base_url: The base used to resolve relative URLs
(eg. in ``
``). If not provided, try to use
the input filename, URL, or ``name`` attribute of file-like objects.
:param url_fetcher: a function or other callable
with the same signature as :func:`default_url_fetcher` called to
fetch external resources such as stylesheets and images.
(See :ref:`url-fetchers`.)
:param media_type: The media type to use for ``@media``.
Defaults to ``'print'``. **Note:** In some cases like
``HTML(string=foo)`` relative URLs will be invalid if ``base_url``
is not provided.

to PDF or another format.
This returns a :class:`~document.Document` object which provides
access to individual pages and various meta-data.
See :meth:`write_pdf` to get a PDF directly.
.. versionadded:: 0.15
:param stylesheets:
An optional list of user stylesheets. (See
:ref:`stylesheet-origins`\.) List elements are :class:`CSS`
objects, filenames, URLs, or file-like objects.
:type enable_hinting: bool
:param enable_hinting:
Whether text, borders and background should be *hinted* to fall
at device pixel boundaries. Should be enabled for pixel-based
output (like PNG) but not vector based output (like PDF).
:returns: A :class:`~document.Document` object.
)r Z_render)r# stylesheetsenable_hintingr. r. r/ renderq s z HTML.renderr c C s | j |j|||S )u Render the document to a PDF file.
This is a shortcut for calling :meth:`render`, then
:meth:`Document.write_pdf() `.
:param target:
A filename, file-like object, or :obj:`None`.
:param stylesheets:
An optional list of user stylesheets. (See
:ref:`stylesheet-origins`\.) The list’s elements are
:class:`CSS` objects, filenames, URLs, or file-like objects.
:type zoom: float
:param zoom:
The zoom factor in PDF units per CSS units.
**Warning**: All CSS units (even physical, like ``cm``)
are affected.
For values other than 1, physical CSS units will thus be “wrong”.
Page size declarations are affected too, even with keyword values
like ``@page { size: A3 landscape; }``
:param attachments: A list of additional file attachments for the
generated PDF document or :obj:`None`. The list's elements are
:class:`Attachment` objects, filenames, URLs or file-like objects.
:returns:
The PDF as byte string if :obj:`target` is not provided or
:obj:`None`, otherwise :obj:`None` (the PDF is written to
:obj:`target`.)

There is no decoration around pages other than those specified in CSS
with ``@page`` rules. The final image is as wide as the widest page.
Each page is below the previous one, centered horizontally.
This is a shortcut for calling :meth:`render`, then
:meth:`Document.write_png() `.
:param target:
A filename, file-like object, or :obj:`None`.
:param stylesheets:
An optional list of user stylesheets. (See
:ref:`stylesheet-origins`\.) The list’s elements are
:class:`CSS` objects, filenames, URLs, or file-like objects.
:type resolution: float
:param resolution:
The output resolution in PNG pixels per CSS inch. At 96 dpi
(the default), PNG pixels match the CSS ``px`` unit.
:returns:
The image as byte string if :obj:`target` is not provided or
:obj:`None`, otherwise :obj:`None` (the image is written to
:obj:`target`.)

An instance is created in the same way as :class:`HTML`, except that
the ``tree`` parameter is not available. All other parameters are the same.
``CSS`` objects have no public attribute or method. They are only meant to
be used in the :meth:`~HTML.write_pdf`, :meth:`~HTML.write_png` and
:meth:`~HTML.render` methods of :class:`HTML` objects.
