[Jmol-developers] Do we need to initialize the graphics environment when Jmol is running headless?

2012-03-17 Thread Jonathan Gutow

I've been working on using 12.0.45 as a server-side static graphics engine for 
the SageMath group.  I've run into the following problem.  The server does not 
run in an X-session, so there is no graphics environment.  This causes an error 
when Jmol is run as Jmol.jar -ionx.  The error seems to imply that we are still 
initializing the look-and-feel, even when there is no GUI.  Is there any reason 
we can't switch this off?  Here's the error:

2012-03-17 Thread Jonathan Gutow

Is this because of the try{...} at line 513 of JmolPanel.java?  Shouldn't this 
be inside the preceding if..., which checks to see if the display and splash 
are enabled?

You can't run it without graphics if you are going to create JPG files.
. If you are doing something else, you can use JmolData.jar, which has
no graphics.
