Re: create a JSVGCanvas from an inputstream

[jonathan wood]

Hi Dao,

Here are a couple of load routines I use frequently ..  Hope they help you
narrow your problem.

Load from a file on the classpath (templated)

        InputStream templateStream =
Canvas.class.getResourceAsStream("template.svg");
        String parser = XMLResourceDescriptor.getXMLParserClassName();
        SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
        SVGDocument doc = null;

        try {
            doc = f.createSVGDocument(null, templateStream);
        } catch (IOException ex) {
        }

       myCanvas.setSVGDocument(doc);


Load from a byte array version:

                Element a = null;
                ByteArrayInputStream bais = new
ByteArrayInputStream(myByteArray);
                String parser =
XMLResourceDescriptor.getXMLParserClassName();
                SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);

                try {
                    a = f.createDocument(null, bais).getDocumentElement();
                } catch (IOException ex) {
                }

                a = (Element) document.importNode(a, true);
