Well, I use v1.6.1 so I know it works with that version. Also this class doesn’t use PNMImage at all, it uses the python image library (PIL) to read images. Perhaps you are trying to run the class as a script? If you are running the example code I posted and all you see is black then most likely the camera needs to be repositioned. In that sample there is no camera control specified so both the camera and the object are at 0,0,0.
