使用蜡染，如下所示：
public static BufferedImage rasterize(File svgFile) throws IOException { final BufferedImage[] imagePointer = new BufferedImage[1]; // Rendering hints can't be set programatically, so // we override defaults with a temporary stylesheet. // These defaults emphasize quality and precision, and // are more similar to the defaults of other SVG viewers. // SVG documents can still override these defaults. String css = "svg {" + "shape-rendering: geometricPrecision;" + "text-rendering: geometricPrecision;" + "color-rendering: optimizeQuality;" + "image-rendering: optimizeQuality;" + "}"; File cssFile = File.createTempFile("batik-default-override-", ".css"); FileUtils.writeStringToFile(cssFile, css); TranscodingHints transprerHints = new TranscodingHints(); transprerHints.put(ImageTransprer.KEY_XML_PARSER_VALIDATING, Boolean.FALSE); transprerHints.put(ImageTransprer.KEY_DOM_IMPLEMENTATION, SVGDOMImplementation.getDOMImplementation()); transprerHints.put(ImageTransprer.KEY_document_ELEMENT_NAMESPACE_URI, SVGConstants.SVG_NAMESPACE_URI); transprerHints.put(ImageTransprer.KEY_document_ELEMENT, "svg"); transprerHints.put(ImageTransprer.KEY_USER_STYLESHEET_URI, cssFile.toURI().toString()); try { TransprerInput input = new TransprerInput(new FileInputStream(svgFile)); ImageTransprer t = new ImageTransprer() { @Override public BufferedImage createImage(int w, int h) { return new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB); } @Override public void writeImage(BufferedImage image, TransprerOutput out) throws TransprerException { imagePointer[0] = image; } }; t.setTranscodingHints(transprerHints); t.transpre(input, null); } catch (TransprerException ex) { // Requires Java 6 ex.printStackTrace(); throw new IOException("Couldn't convert " + svgFile); } finally { cssFile.delete(); } return imagePointer[0];}
