SVGSurface can take a file like object instead of a filename, so we use the response. Rendering happens on the SVGSurfaces Context. When .finish() is called on SVGSurface, it does it's rendering (in this case SVG data, to the response). Almost that, but not quite –

How does this work? Thanks response = HttpResponse(mimetype=’image/svg xml’)

SVG seems to get more attention these days, even from Microsoft. It's great for producing high quality and detailed graphics at large sizes. A nice paper I found on SVG vs Canvas http://www.svgopen.org/2009/papers/54-SVG_vs_Canvas_on_Trivial_Drawing_Application/ Thanks for your feature request.

I had a look at the generated SVG and it could definitely be nicer (theres no way to name particular bits). You might be able to generate a piece of SVG with cairo, then put the XML into some DOM library where you could add a css ID or Path to it. Really we need a new bit of the cairo-svg api that will let us output metadata as we go. Post here if you do anything though as I think there should be more Cairo and SVG on the web.

Any thoughts on how to hook this up for interactivity with ecmascript? Wow, you beat me, I was working on a quite similar setup past week, but had to back off due to other tasks.

The current version of the java-gnome bindings is 4.x, for a while ubuntu had the old bindings installed (my test vm seems to). To check which version you have look in /usr/share/java gtk-4.0.jar Is the correct version gtk2.10 Is the old version I managed dist-upgrade my ubuntu to karmic koala, but $ sudo apt-get upgrade libjava-gnome-java Was still not enough... however: $ sudo apt-get remove libjava-gnome-java $ sudo apt-get install libjava-gnome-java DID install gtk-4.0.jar. You may need to manually set the classpath: $ export CLASSPATH=/usr/share/java/gtk-4.0.jar Unfortunately I don't have the vm I used to write this tutorial with at the moment, so it's a little tricky to test stuff - if I get time I'll try and get everything working again and fix any gaps in the tutorial.

The other errors look like java gnome is not in the classpath. Hi,
