wmf格式转换成svg

把wmf格式转成svg格式，这样就能在浏览器中显示了

需要第三方jar包：wmf2svg-0.9.6.jar

//wmf格式的图片转换成svg格式 private void convert(String file,String dest) throws Exception{ InputStream in = new FileInputStream(file); WmfParser parser = new WmfParser(); final SvgGdi gdi = new SvgGdi(false); parser.parse(in, gdi); Document doc = gdi.getDocument(); OutputStream out = new FileOutputStream(dest); if (dest.endsWith(".svgz")) { out = new GZIPOutputStream(out); } output(doc, out); } private void output(Document doc, OutputStream out) throws Exception { TransformerFactory factory = TransformerFactory.newInstance(); Transformer transformer = factory.newTransformer(); transformer.setOutputProperty(OutputKeys.METHOD, "xml"); transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC,"-//W3C//DTD SVG 1.0//EN"); transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"/TR/2001/REC-SVG-20010904/DTD/svg10.dtd"); transformer.transform(new DOMSource(doc), new StreamResult(out)); ByteArrayOutputStream bos = new ByteArrayOutputStream(); transformer.transform(new DOMSource(doc), new StreamResult(bos)); out.flush(); out.close(); }
