Generating ecore diagram image file programmatically [message #758707]

Hi,

I have a m2m tool which output is ecore metamodel. It works outside eclipse as a command line tool.

I would like to generate class diagram (in svg, png, or some other format) file from the newly created ecore metamodel. I looked at org.eclipse.emf.ecoretools.diagram packages, but haven't been able to figure out how to use it.

I would really appreciate any tips or hints on how to best achieve this task. Thank you.

Paulius,

I don't know the answer, but what I'd do to find it myself is set a
breakpoint in the constructor of some notation model class that I know
is created and used in the final diagram that the wizard produces. Then
I would look up the stack to see what leads to the creation of the diagram.

Thanks!
I debugged and saw that diagram notation instance is created in ViewService.createDiagram(...). Then I can export image using OffscreenEditPartFactory and CopyToImageUtil.

However ViewService needs to have a plugin activated (in this case I guess its EcoreDiagramEditorPlugin). I am not sure how to embed Plugin in my headless application. Any ideas?

Paulius,

I don't know anything about ViewService other that it's part of the GMF
runtime and hence it's more of a GMF question. I don't see why it needs
to use EcoreDiagramEditorPlugin.

That's what I found out a couple of weeks ago and gave up on this goal ;-(

If you find a solution please report it here!
