As of matplotlib 0.91.1, savefig() supports saving to a file-like object for most backends (excluding Gtk and Wx). You can pass in a StringIO object to savefig for instance, and then pass its content to the XML parser of your choice. (There is no way to get DOM objects directly, since the SVG backend actually writes the XML content directly as a stream of bytes). You can specify SVG as your output by either setting the backend appropriately or passing a "format" kwarg to savfig, e.g. savefig(fileobj, format="svg") Cheers, Mike bplewe wrote: > [Fairly new at matplotlib, but very happy with it so far] > > Is it possible to retrieve images rendered by one of the backends as an > object, rather than just saving to a file? > > Specifically, I need to render graphs to SVG code, that I can turn into a > DOM object for further manipulation.
