I want to get high quality images of my network created in Jung. ExportDialog of the FreeHEP VectorGraphics library gives this option in the form of a dialog box. 

ExportDialog export = new ExportDialog();
export.showExportDialog(vv, "Export view as ...", vv, "export");

Where vv is the VisualizationViewer that I want to print out. I want to avoid choosing the file type and location everytime and automize the export so that the file is automatically saved to a folder as a pdf file. So I wrote the following code but it does not generate the picture that I want.

  Properties p = new Properties();
  p.setProperty("PageSize","A4");
  VectorGraphics g = new PSGraphics2D(new File("Output.pdf"),vv.getSize()); 
  g.setProperties(p);
  g.startExport(); 
  vv.print(g); 
  g.endExport();

To export pdf files: 

 VectorGraphics g = new PDFGraphics2D(new File("ResultImages/Output.pdf"), vv);
