new Float(1.0));
TranscoderInput input = new TranscoderInput(new FileInputStream("C:/Taha/SmartPlannerNew/rectangles.svg"));
OutputStream ostream = new FileOutputStream("C:/Taha/SmartPlannerNew/out.jpg");
TranscoderOutput output = new TranscoderOutput(ostream);
try {
transcoder.transcode(input, output);

Batik is exactly what you are looking for, is totally stable, and there really is not much else.
蜡染正是您要找的，完全稳定，除此之外别无他物。
You can read the handy official tutorial on using the transcoder portion of batik: http://xmlgraphics.apache.org/batik/using/transcoder.html
