following way
====================================
		FileOutputStream fos = new FileOutputStream("d:\\gvs.tiff");
            TiledImageTranscoder tit = new TiledImageTranscoder();
            tit.addTranscodingHint(KEY_WIDTH, new Float(10240));
            tit.transcode(new TranscoderInput("file:" + "d:\\test.svg"), 
                          new TranscoderOutput(fos));

   Actually, you can't just replace TIFF with JPEG in the code because
there is no JPEG encoder capable of taking a rendered image and transcoding
it to a JPEG file (Actually I think javax.imageio may have one but we
are currently based on JDK 1.3 so in that context we don't have it).

   But it is true that if you can switch to using TIFF then the tiled
transcoder
is _much_ better for very large images.
