Size of SVGCanvas

Hi

 

While trying to read the size of the SVGCanvas with getSVGDocumentSize().getWidth() there's a null pointer exception. I trying to put the canvas into a window.

The code:

        File f = new File("t1.svg");

        svgCanvas2.setURI(f.toURL().toString());

        win = new JWindow();

        final JPanel pop = new JPanel();

        win.setLocation(800,100);

        System.out.println(svgCanvas2.getSVGDocumentSize().getWidth());

        pop.add(svgCanvas);

        win.getContentPane().add(pop);

        win.setVisible(true);

 

The code is taken from the Batik SVGCanvas Tutorial and modified with JWindow instead of JFrame. What's wrong while retrieving the svg size ? Are there

Other possibilities to get the size. If I use the example code with JWindow I also get a frame around the window. How do I get rid of it.

 

Thanks

Markus
