Drawing svg

Hi batik-users,

I still want to draw an svg to my graphics context. I tried the following
little java programm without success. I would have expected that the svg
woulb be drawn to my frame. (At least after waiting some time to give the
app the chance to load the svg file and then forcing the frame to be redrawn
...)

What am I missing here?
Thanks
Charly


import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Color;
import java.awt.geom.AffineTransform;

import javax.swing.JFrame;
import javax.swing.JPanel;

import org.apache.batik.swing.JSVGCanvas;

public class xmt extends JFrame
{
    public static void main(String[] args) {
        xmt myFrame = new xmt();
        myFrame.setSize(400,400);
        myFrame.setVisible(true);
    }

    private JSVGCanvas svg;

    xmt() {
        svg = new JSVGCanvas();
        svg.setURI("file:../fc02.svg");
    }


    public void paint(Graphics g) {
System.out.println("paint");
        super.paint(g);
//      svg.setPaintingTransform(new AffineTransform(0.5, 0.0, 0.0, 0.5,
100.0, 100.0));
        svg.paintComponent(g);
    }
}

If you are using JSVGCanvas from Batik, it might be better if you add JSVGCanvas into the frame / panel as a component and let it paint itself.
JSVGCanvas is Swing JComponent, you could add it directly into frame /
panel.

   You haven't provided a size for the JSVGCanvas, so it's size is zero.
As to what an affine transform is see the JavaDocs for: 
        java.awt.geom.AffineTransform

   Take a look at the Batik Wiki:
        http://wiki.apache.org/xmlgraphics-batik/BootSvgAndCssDom

   The 'rootGN' has a method called 'paint' that takes
a java Graphics2D.
