Hi,
I know this question might sound a little bit strange:
Assume we are given a model instance file and a corressponding notation
file. Is there a change to produce an image of the given instance
using the GMF API without launching the Eclipse UI?
Regards,
Alex

Thanks for your hint. I found these classes and created a headless RCP
which runs the image conversion.
Unfortunately I run into some problems with the initialization.
Loading the class ImageFileFormat fails with the following exception:

Do I have to add some initialization steps?

Thanks for analyzing the problem.
I entered the bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=163380
