pyOpenSlide
I've created some python bindings for OpenSlide using Cython.
You can download them here: pyOpenSlide_0.5.tar.gz | pyOpenSlide_0.5.zip
pyOpenSlide is released under the LGPL, the same terms as OpenSlide. This is an early release, and not all functionality from OpenSlide is supported yet. Please let me know if this software is useful to you and if you encounter any bugs: my email is kerwin at osc.edu.
