    There are two problem areas in this issue:
    
    1. SVGDocumentBuilderConfigurator.setTransformer does not accept
    identify transformer because it treats null transformer as
    identity transformer:
    
    2. IlvSubgraphRenderer.drawIcon assumes that the transformer
    parameter is not null so it accesses the transformer without
    checking if it is not null:
    

Local fix

  • If the transformer of the current view is identity, temporary
    translate the transformer, set the transformer to the
    SVGDocumentBuilderConfigurator, then re-translate the
    transformer of the current view back to identify.
    
    public void saveAsSVG(IlvDiagrammer diagrammer, File f) throws
    IOException {
        IlvSDMView currentView = diagrammer.getView();
        // Create a view at the needed size
        IlvManager manager = currentView.getManager();
        // workaround
        boolean identity =
    currentView.getTransformer().isIdentity();
    
        SVGStreamFactory streamFactory = new SVGStreamFactory();
        manager.setStreamFactory(streamFactory);
        // workaround
       if( identity )
         currentView.translate(1, 1, false);
    
    streamFactory.getBuilderConfigurator().setTransformer(currentVie
    w.getTransformer());
        if( identity)
         currentView.translate(-1, -1, false);
        /**/
        // ends workaround
        manager.write(f.getCanonicalPath());
      }
