Export diagram without workspace [message #1753667]

Hi,

I'm currently trying to export my diagram as SVG without workspace (running on a server).
First of all, is it possible ? If so, how to create a Sirius Session in order to use an ExportAction for example ?

Thanks in advance !

Cheers,

Bastien.

Hi,

you can do something like

        // Get session from an absolute path (not in a workspace)
        URI sessionResourceURI = URI.createFileURI("D:/folder/representations.aird");
        Session session = SessionFactory.INSTANCE.createSession(sessionResourceURI, new NullProgressMonitor());
        session.open(new NullProgressMonitor());
        // Get the expected representation (here the first of the first DView)
        DViewQuery query = new DViewQuery(session.getOwnedViews().iterator().next());
        DRepresentation representation = query.getLoadedRepresentations().get(0);
        // Export it as SVG image
        ExportFormat exportFormat = new ExportFormat(ExportDocumentFormat.NONE, ImageFileFormat.SVG);
        DialectUIManager.INSTANCE.export(representation, session, new Path("D:/folder/image.svg"), exportFormat,
                new NullProgressMonitor());

Regards,

Laurent

Hi,

I answer on this topic near one year later because I found myself in the same situation that the topic author.
I want to export diagram representations from an acceleo script which can be launched in standalone.

For that, I want to use SessionFactory.INSTANCE.createSession.
However, for creating this session, an error in thrown because of the register factory. So, I added this line in my main acceleo java class.

 Resource.Factory.Registry.INSTANCE.getResourceFactoryRegistry().getExtensionToFactoryMap().put("aird",  new XMIResourceFactoryImpl());

But it's not enough, I have then this error :

Is there additional steps that I have to do to use the create session ?

Thanks in advance,

Hi Marianna,

It seems that you do not use the expected resource factory: aird resources needs the org.eclipse.sirius.business.internal.resource.AirDResourceFactory (it brings the automatic migration of Sirius resources).

Note that you could also try org.eclipse.sirius.business.api.session.INSTANCE.getSession(uri, progressmonitor) and then open the session or org.eclipse.sirius.business.api.session.INSTANCE.openSession(URI, IProgressMonitor, UICallBack) (with SiriusEditPlugin.getPlugin().getUiCallback() or a new org.eclipse.sirius.tools.api.command.ui.NoUICallback regarding your context) instead of the use of the session factory.

Regards

Hi Maxime,

I try to export diagram from java application with Marianna.

When I use the following code :

org.eclipse.sirius.business.api.session.SessionManager.INSTANCE.openSession(airdURI, new NullProgressMonitor(), SiriusEditPlugin.getPlugin().getUiCallback());

The application returns the following exception : "Workspace is closed ".

When I want to create a Session with the following code :

Session session = SessionFactory.INSTANCE.createSession(airdURI, new NullProgressMonitor());
session.open(new NullProgressMonitor());

The application returns the following exception :
