Creating an image from SGT in java

JPlotLayout jpl; 
// initialize and add plots to jpl ... ommitted here.

// Get graphic
int width = jpl.getWidth();
int height = jpl.getHeight();
BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics g = img.getGraphics();
jpl.paint(g);

// Save to a file
try {
    BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("some.jpg"));
    JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
    JPEGEncoderParam param = encoder.getDefaultJPEGEncoderParam(img);
    int quality = 100;
    quality = Math.max(0, Math.min(quality, 100));
    param.setQuality((float) quality/100F, false);
    encoder.setJPEGEncoderParam(param);
    encoder.encode(img);
    out.close();
}
catch (IOException e) {
    // Log or deai with exception
}
