蜡染在SVGGraphics2D中加载SVG文件

Question

I use batik for drawing svg, and save it. That work.

But now i try to load my svg file and add somthing.

I use this fonction for load my svg file

private static SVGDocument loadSVGDocument(String uri) {
    String parser = XMLResourceDescriptor.getXMLParserClassName();
    SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser);
    SVGDocument svgDocument = null;
    try {
        //svgDocument = factory.createSVGDocument(IMAGE_SVG);
        svgDocument = factory.createSVGDocument(uri);
    } catch (IOException e) {
        System.out.println(e.getMessage());
    }
    return svgDocument;
}

and this for have SVGGraphics2D

SVGDocument svgDocument = loadSVGDocument(TEST_SVG);
SVGGraphics2D g = new SVGGraphics2D(svgDocument);

When i debug my SVGDocument have all children and attribut null And when i generate image, is empty and size is 400x400

Where is problem when i load my SVG file?

Answer 1

I every body I find a solution for my case

I compare my generation and my file. First think i have svg root and one child g only. svg root don t have with and height

I go search width and height

        Element elSVG = svgDocument.getRootElement();
    String width = elSVG.getAttribute("width");
    String height = elSVG.getAttribute("height");

and after root

NodeList nodes = elSVG.getElementsByTagName("g");
    Node node = nodes.item(0);
    Element el = null;
    if(Node.ELEMENT_NODE == node.getNodeType()) {
        el = (Element)node;
    }

and for the end add everything to graphics

        SVGGraphics2D g = new SVGGraphics2D(svgDocument);
    g.setTopLevelGroup(el);
    g.setSVGCanvasSize(new Dimension(Integer.parseInt(width), Integer.parseInt(height)));

And that works for only one child to svg. For me is OK for now.

And i try to add an other think like rectangle and that work to.
