    Description

      Hi,
      when I try to follow the description on
      http://xmlgraphics.apache.org/batik/using/transcoder.html#createImage
      to create a jpg-image file from a svg-file in a JUnitTest, I get the following error message:

      org.apache.batik.transcoder.TranscoderException: null
      Enclosed Exception:
      null

      The batik version I use is 1.7.

      First I tried to transform a created svg-file into jpeg-file in my own application, but I get the same exception, so I copied the example code from the previous mentioned website in a JUnit-Testcase to figure out if I have done anything wrong in my application. But I got the same problem again, with the copied and pasted code (see above).

      When I ran the rasterizer.jar file to convert the image, there is no such an exception thrown. I looked at the code from SVGGenerator from the Rasterizer application, but I doesn´t found a solution, so far to solve the problem.

      So here is the code from my JUnitTest method:

      public void testJPEGTranscoder() {

      // Create a JPEG transcoder
      JPEGTranscoder t = new JPEGTranscoder();

      // Set the transcoding hints.
      t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY, new Float(.8));

      // Create the transcoder input.
      String svgURI;
      try

      { svgURI = new File("test/TestInput.svg").toURL().toString(); TranscoderInput input = new TranscoderInput(svgURI); // Create the transcoder output. OutputStream ostream = new FileOutputStream( "test/TestOutput.jpg"); TranscoderOutput output = new TranscoderOutput(ostream); // Save the image. t.transcode(input, output); // Flush and close the stream. ostream.flush(); ostream.close(); // System.exit(0); }

      catch (MalformedURLException e)

      { // TODO Auto-generated catch block e.printStackTrace(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); }

      catch (TranscoderException e)

      { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }

      }

      Thanks in advance for your help,
      ks
