This is sometimes caused by the parent component whose size has not been set.

Dear All, I have a component extending the JSVGCanvas class that needs to render an SVG file from disk. I am currently calling canvas.setURI(url.toString()) which seems to find and load the file but it then puts up an exception window complaining of zero dererminants when trying to create an inverse AffineTransform. This is the part of code that loads the document.. // cl is the source of the SVG url JSVGCanvas component = new JSVGCanvas(); javax.swing.JOptionPane.showMessageDialog(null, cl.getURL().toString()); component.setURI(cl.getURL().toString()); document = component.getSVGDocument(); javax.swing.JOptionPane.showMessageDialog(null, "Document loaded into component : " + document); The final line shows null as the document. Shortly after I get the affine transform exceptions. The svg file is about as simple as it gets: <svg xmlns="http://www.w3.org/2000/svg"; xmlns:xlink="http://www.w3.org/1999/xlink"; width="150" height="150"> <circle style="fill:yellow" cx="200" cy="100" r="90" /> </svg> and the exception is: java.awt.geom.NoninvertibleTransformException: Determinant is 0 at java.awt.geom.AffineTransform.createInverse(AffineTransform.java:1898) at org.apache.batik.swing.gvt.JGVTComponent.setRenderingTransform(Unknown Source) at org.apache.batik.swing.svg.JSVGComponent.computeRenderingTransform(Unknown Source) at org.apache.batik.swing.gvt.JGVTComponent.setGraphicsNode(Unknown Source) at org.apache.batik.swing.svg.JSVGComponent.access$201(Unknown Source) at org.apache.batik.swing.svg.JSVGComponent$SVGListener.gvtBuildCompleted(Unkno wn Source) at org.apache.batik.swing.svg.GVTTreeBuilder$2.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:154) at java.awt.EventQueue.dispatchEvent(EventQueue.java:337) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.ja va:131) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java :98) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:85) Is there a better way to load a document from file? I dont really want the canvas at this stage. I know of the SAXSVGDocumentFactory class but the constructor needs a classname for a SAX parser, which I cannot find. Can anyone shed light on this problem?
