10 The document module contains two classes: :class:`document` and :class:`page`. A
11 :class:`document` consists of one or several :class:`page`\ s.
17 A :class:`page` is a thin wrapper around a :class:`canvas`, which defines some
18 additional properties of the page.
21 .. class:: page(canvas, pagename=None, paperformat=None, rotated=0, centered=1, fittosize=0, margin=1 * unit.t_cm, bboxenlarge=1 * unit.t_pt, bbox=None)
23 Construct a new :class:`page` from the given :class:`canvas` instance. A string
24 *pagename* and the *paperformat* can be defined. See below, for a list of known
25 paper formats. If *rotated* is set, the output is rotated by 90 degrees on the
26 page. If *centered* is set, the output is centered on the given paperformat. If
27 *fittosize* is set, the output is scaled to fill the full page except for a
28 given *margin*. Normally, the bounding box of the canvas is calculated
29 automatically from the bounding box of its elements. Alternatively, you may
30 specify the *bbox* manually. In any case, the bounding box is enlarged on all
31 sides by *bboxenlarge*.
34 Class :class:`document`
35 -----------------------
38 .. class:: document(pages=[])
40 Construct a :class:`document` consisting of a given list of *pages*.
42 A :class:`document` can be written to a file using one of the following methods:
45 .. method:: document.writeEPSfile(file, title=None, strip_fonts=True, text_as_path=False, mesh_as_bitmap=False, mesh_as_bitmap_resolution=300)
47 Write a single page :class:`document` to an EPS file. *title* is used as the
48 document title, *strip_fonts* enabled font stripping (removal of unused glyphs),
49 *text_as_path* converts all text to paths instead of using fonts in the output,
50 *mesh_as_bitmap* converts meshs (like 3d surface plots) to bitmaps (to reduce
51 complexity in the output) and *mesh_as_bitmap_resolution* is the resolution of
52 this conversion in dots per inch.
55 .. method:: document.writePSfile(file, writebbox=False, title=None, strip_fonts=True, text_as_path=False, mesh_as_bitmap=False, mesh_as_bitmap_resolution=300)
57 Write :class:`document` to a PS file. *writebbox* add the page bounding boxes to
58 the output. All other parameters are identical to the :meth:`writeEPSfile`
62 .. method:: document.writePDFfile(file, title=None, author=None, subject=None, keywords=None, fullscreen=False, writebbox=False, compress=True, compresslevel=6, strip_fonts=True, text_as_path=False, mesh_as_bitmap=False, mesh_as_bitmap_resolution=300)
64 Write :class:`document` to a PDF file. *author*, *subject*, and *keywords* are
65 used for the document author, subject, and keyword information, respectively.
66 *fullscreen* enabled fullscreen mode when the document is opened, *writebbox*
67 enables writing of the crop box to each page, *compress* enables output stream
68 compression and *compresslevel* sets the compress level to be used (from 1 to
69 9). All other parameters are identical to the :meth:`writeEPSfile`.
72 .. method:: document.writetofile(filename, *args, **kwargs)
74 Determine the file type (EPS, PS, or PDF) from the file extension of *filename*
75 and call the corresponding write method with the given arguments *arg* and
79 Class :class:`paperformat`
80 --------------------------
83 .. class:: paperformat(width, height, name=None)
85 Define a :class:`paperformat` with the given *width* and *height* and the
88 Predefined paperformats are listed in the following table
