Subject: Transcoded images are being clipped....


I'm probably missing something really simple here. I'm using Batik 1.6
to generate svg output from a java application (using SVGGraphics2D) and
then using a transcoder to convert that output to an image format. The
problem I'm seeing is that the generated image is clipped/cut off on the
right hand side. The original application dimensions are 600x400 (width
x height) pixels, and the generated image is also that size, but nothing
seems to draw beyond the 400-pixel mark on the right side. I'd
appreciate any suggestions on how to resolve this.
 
Here are the details:
 
In a small test application's paint() method I'm drawing a filled
rectangle, overlaying a few lines and outputting some text. I generate
an svg file from this using the following code and, when viewed in a
browser it looks fine:
            Dimension dim = panel.getSize();
            // Get a DOMImplementation
            DOMImplementation domImpl =
                    GenericDOMImplementation.getDOMImplementation();
            // Create an instance of org.w3c.dom.Document
            Document document = domImpl.createDocument(null, "svg",
null);
            // Create an instance of the SVG Generator
            SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
 
            // Ask to render into the SVG Graphics2D implementation
            panel.print(svgGenerator);
 
            String svgFilePath = "c:\\temp\\batik.svg";
            StringWriter svgOutput = new StringWriter();
            svgGenerator.stream(svgOutput);
            FileOutputStream svgfout = new
FileOutputStream(svgFilePath);
            svgfout.write(svgOutput.toString().getBytes());
            svgfout.flush();
            svgfout.close();

Then I create a StringReader from the svg output and attempt to
transcode the output to an image format (jpeg/png): 
    StringReader reader = new StringReader(svgOutput.toString());
    JPEGTranscoder jpegt = new JPEGTranscoder();
     jpegt.addTranscodingHint(JPEGTranscoder.KEY_QUALITY,
                    new Float(.8));
     jpegt.addTranscodingHint(JPEGTranscoder.KEY_HEIGHT, new
Float(dim.height));
     jpegt.addTranscodingHint(JPEGTranscoder.KEY_WIDTH, new
Float(dim.width));

     FileOutputStream fout = new
FileOutputStream("c:\\temp\\batik.jpg");
     TranscoderOutput output = new TranscoderOutput(fout);
     TranscoderInput input = new TranscoderInput(reader);
      transcoder.transcode(input, output);
 
      fout.flush();
      fout.close();
 
 
Thanks in advance.
