Looking at osgconv's source code I understood that the way it creates a graphics context is by means of 'pbuffer'...and looking at other mails too, I understood also that this will avoid to actually open a rendering window, right?
Unfortunately such a creation always fails for me. What could be the reason for not being able to create a context with a pbuffer? Thanks.
