      Description

      code:
      public static void svgToPng(String svgPath, String pngFile) throws Exception {
      File svg = new File(svgPath);
      FileInputStream wmfStream = new FileInputStream(svg);
      ByteArrayOutputStream imageOut = new ByteArrayOutputStream();
      int noOfByteRead = 0;
      while ((noOfByteRead = wmfStream.read()) != -1)

      { imageOut.write(noOfByteRead); }

      imageOut.flush();
      imageOut.close();
      wmfStream.close();

      ByteArrayOutputStream jpg = new ByteArrayOutputStream();
      FileOutputStream jpgOut = new FileOutputStream(pngFile);

      byte[] bytes = imageOut.toByteArray();
      PNGTranscoder t = new PNGTranscoder();
      TranscodingHints hints = new TranscodingHints();
      ///hints.put(WMFTranscoder.KEY_INPUT_HEIGHT, 1000);
      //hints.put(WMFTranscoder.KEY_INPUT_WIDTH, 8000);
      //hints.put(WMFTranscoder.KEY_WIDTH, 800);
      // hints.put(WMFTranscoder.KEY_HEIGHT, 600);
      //t.setTranscodingHints(hints);
      TranscoderInput in = new TranscoderInput(new ByteArrayInputStream(bytes));
      TranscoderOutput out = new TranscoderOutput(jpg);
      t.transcode(in, out);
      jpgOut.write(jpg.toByteArray());
      jpgOut.flush();
      jpgOut.close();
      imageOut = null;
      jpgOut = null;
      }
