========================================================================
This module provides function ``convert`` that convert all or selected
items placed on given canvas object.
Supported items:
* lines
* lines with arrows
* polygons
* smoothed lines and polygons
* ovals (i.e. circle & ellipse)
* arcs (all kind, i.e. ARC, CHORD, PIESLICE)
* rectangles
* text (**unwrapped** only i.e. attribute ``width = 0``)
Unsupported items:
* images
* bitmaps
* windows
Stipples are not applied.
Public functions
------------------------------------------------------------------------
``convert(document, canvas, items=None, tounicode=None)``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* ``document`` --- SVG document, object that support DOM, i.e. provides
``createElement`` method etc. (function ``SVGdocument`` can be used
to get such object)
* ``canvas`` --- Tkinter.Canvas object
* ``items`` --- list of objects to convert; if ``None`` then all items
are converted
* ``tounicode`` --- user function that should return proper unicode
string if Tkinter app use other then ASCII encoding. By default
``tounicode = lambda text: unicode(text).encode('utf-8')``.
Thanks to **Jan Böcker** who provided solution.
``SVGdocument``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Takes no arguments, returns SVG document; class provided in standard
``xml.dom.minidom`` module is used.
``saveall(filename, canvas, items=None, margin=10, tounicode=None)``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Helper function: saves whole canvas or selected items in SVG file,
sets proper dimensions, and viewport; additional ``margin`` can
be set.
``warnings(mode)``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Module might emit warnings. By default it use custom function which
prints message on the standard error. You can change this by calling
method ``canvasvg.warnings(mode)`` with three possible values:
* ``canvasvg.PYTHON`` --- use ``warn`` from the standard module
``warnings``;
* ``canvasvg.MODULE`` --- use the custom function;
* ``canvasvg.NONE`` --- do not print any message.
``configure(*flags)``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Module might use either ```` or ```` tag for segment
representation. By default it uses ````. The behaviour could be changed
globally by calling ``canvasvg.configure(*flags)`` with one of consequent
values:
* ``canvasvg.SEGMENT_TO_LINE`` --- use ```` tag;
* ``canvasvg.SEGMENT_TO_PATH`` --- use ```` tag.
