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,
