David, There isn't currently a programmatic way of doing this, but it wouldn't be too hard to make one. I'll put onto the todo list support for commands like: ray 1024; ray width=800; height=600; where the second axis is calculated.
Note that we're currently missing an API function for getting the viewer size (we'll need to add that), but you can rip it out of a session dictionary constructed on-the-fly (which is grossly inefficient, but it works): print cmd.get_session()['main'][0:2] [640,480] Cheers, Warren > -----Original Message----- > From: pymol-users-ad...@lists.sourceforge.net > [mailto:pymol-users-ad...@lists.sourceforge.net] On Behalf Of > David A.
