android providing different drawable resources for orientations

I would like to provide different drawable resources for different orientations. What is the proper folder name to provide a landscape and portrait version of a drawable? I looked through the android documentation and haven't seen anyt开发者_如何学Pythonhing like drawable-hdpi-land or drawable-hdpi-port. Are these the proper names?

it's drawable-land-hdpi etc, see the documentation for the full order:
