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:

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
