Is omc/omshell capable of generating annotation diagrams in a headless environment? I am especially interested in something I can use over the Python interface under a headless Linux environment. Ideally, i would like a vector-based format, but png could work just as well.

If the notebook comes into play, has anyone been able to achieve this via the command line?

I haven't found anything supporting this in the user's guide, or in looking over the API docs.

If anyone has an answer, or can suggest another method, that would be greatly appreciated!
