Python binding to ImageMagick

I am looking for a good Python binding to ImageMagick, but there seem a lot of bindings already. I am not sure that which of these is the right tool for my job. Can you guys recommend me one?

Here is the list of my requirements and preferences (in order of importance):

1. Must be available on PyPI (to simplify our deployment)
2. Prefer ctypes over C API extension — we will go PyPy 开发者_高级运维soon
3. Pythonic API design and naming conventions
4. Good documentation (especially API references)

I found the package myself: magickwand is a ctypes-based ImageMagick binding for Python. Yet it has no documentation at all, it still satisfies most of my requirements.

Plus: I finally started my own project: Wand.
