generate image without opening a display

To generate an image without opening a display, add the -Djava.awt.headless=true option to your Java command. E.g.:

Code:

java -classpath lib/MarvinBeans.jar -Djava.awt.headless=true chemaxon.formats.MolConverter

An alternative workaround for image generation problem:





You can use Xvfb virtual X11 server if there is not an X server on your machine.

Code:

Xvfb :2 -screen 0 649x480x24 2>>logfile & export DISPLAY=:2

Its documentation can be found on the xfree86 site: http://www.xfree86.org/4.2.0/Xvfb.1.html
