Need a sample to merge SVG Documents

[Laurent Caron <la...@gmail.com>]

Hi,

I've got 6 different documents that represents "layers" (like photoshop
ones). They all have the same size.

To represent the layers, I've simply built a Frame, and JSVGCanvas (1 per
layer), and simply use frame.add(canvas).
This works fine, but it is a bit slow, and I need to implement scrollbars.

My first idea is to merge all layers in one unique document. Does anybody
can provide me a piece of code that
can achieve this goal ?

Thanks,

Laurent

Hi,

Forget it, I found another message in the archive. Anyway, the solution is :

        // Merge
        File file1 = new File("first.svg");
        File file2 = new File("second.svg");
        String parser = XMLResourceDescriptor.getXMLParserClassName();
        SAXSVGDocumentFactory factory = new
SAXSVGDocumentFactory(parser);

        SVGDocument document1 = null;
        SVGDocument document2 = null;
        try {
            document1 = (SVGDocument) factory.createDocument(file1.toURL
().toString());
            document2 = (SVGDocument) factory.createDocument(file2.toURL
().toString());
        } catch (MalformedURLException e1) {
            e1.printStackTrace();
            System.exit(1);
        } catch (IOException e1) {
            e1.printStackTrace();
            System.exit(1);
        }

        // Copy the document2 inside document 1

        Node newDocument = document1.importNode(document2.getDocumentElement(),
true);


// And append the result

        document1.getDocumentElement().appendChild(newDocument);
        canvas.setSVGDocument(document1);

Not so difficult :)
