DocumentWriter
===================
DocumentWriter objects are used to create new documents in several formats.
Constructors
------------
.. class::
DocumentWriter(buffer, format, options)
DocumentWriter(filename, format, options)
Create a new document writer to create a document with the specified format and output options. If ``format`` is ``null`` it is inferred from the filename. The ``options`` argument is a comma separated list of flags and key-value pairs.
For supported output ``format`` values and ``options`` see
:doc:`/reference/common/document-writer-options`.
:param Buffer buffer: The buffer to output to.
:param Buffer filename: The file name to output to.
:param string format: The file format.
:param string options: The options as key-value pairs.
.. code-block::
var writer = new mupdf.DocumentWriter(buffer, "PDF", "")
Instance methods
----------------
.. method:: DocumentWriter.prototype.beginPage(mediabox)
Begin rendering a new page. Returns a `Device` that can be used to render the page graphics.
:param Rect mediaBox: The page size.
:returns: `Device`
.. code-block::
var device = writer.beginPage([0, 0, 100, 100])
.. method:: DocumentWriter.prototype.endPage()
Finish the page rendering.
.. code-block::
writer.endPage()
.. method:: DocumentWriter.prototype.close()
Finish the document and flush any pending output. It is a
requirement to make this call to ensure that the output file is
complete.
.. code-block::
