export ecore model to an image [message #219630]

Hello!

I'm developing an application, that handles ecore models and diagrams. One
part should be, that diagrams are exported to image files automatically by
the application. There should be no diagram editor visible to the user. So
the solution with the context menu doesn't work.
I have a model and a diagram file and what I want to get is an image file.
Is there a possibility to use parts of gmf and emft to do this?

Hello Sebastian,

yes you can do so.
GMF provides all you need.

First of all, create a DiagramEditPart-instance with
OffScreenEditPartFactory and second use the CopyToImageUtil to save the
diagram to a file.
All works without ever opening an editor.
If you need further help, let me know.

Regards, Thomas

Hello Thomas,

this is exactly that what I want to do. Thanks.
At the moment my problem is, that I don't know how to load an ecore
diagram file into a Diagram-Object. So I can't create a DiagramEditPart.
Can you give me a hint how should I do this, please?

regards
Sebastian

To get to Diagram object I tried to use the EcoreTools Plugin.

Resource resource =
EcoreDiagramEditorUtil.createDiagram(diagramURI,
modelURI, new SilentProgressMonitor());

Diagram diagram = (Diagram) resource.getContents().get(0);

With this I get a Diagram, but the export to an SVG-Imgae results only in
a SVG-Document with no graphical elements in it.

DiagramEditPart diagramEditPart = OffscreenEditPartFactory
.getInstance().createDiagramEditPart(diagram, new Shell());
CopyToImageUtil copyToImageUtil = new CopyToImageUtil();
copyToImageUtil.copyToImage(diagramEditPart, destination,
ImageFileFormat.SVG, new SilentProgressMonitor());

Where could be a mistake?

regards
Sebastian
