I didn't find an easy way, but maybe I was making it difficult for myself deliberately. For example, I wanted to render SVG using something that is compatible with PyGame, and I ended up looking at Cairo, but this led to a lot of library rebuilding that didn't end up producing decent results with OpenWrt: there was still a colour channel swapping problem that wouldn't go away. See the following section on the wiki for some more information: http://en.qi-hardware.com/wiki/User:PaulBoddie#Experimenting_with_Small- Screen_User_Interfaces (That led me to doing stuff with Debian instead of OpenWrt, but I still haven't got into the act of rebuilding packages with different capabilities, mostly because cross-compiling Debian packages is not a perfected process by any means.) Maybe there are some libraries that do SVG on top of SDL directly. Certainly, the SDL stack is pretty well supported in the firmware on the Ben. I copied Werner and made use of the SDL_gfx support for a recent endeavour: http://en.qi-hardware.com/wiki/Ben_Pololu_IMU > Thanks to everyone working on the Ben Nanonote.

It's certainly a lot more fun in different ways than everyone originally anticipated, that's for sure. :-) Paul _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
