Save graphic as picture

Question

I need to save a graphic (Multichart Object) as a JPG file. Can you help me ?

Answer 1

Here's the method used in JFreeChart:
    public static void writeChartAsJPEG(OutputStream out, JFreeChart chart, int width, int height)
        throws IOException {
        BufferedImage image = chart.createBufferedImage(width, height);
        JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
        JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(image);
        param.setQuality(1.0f, true);
        encoder.encode(image, param);
    }This approach ought to work for any BufferedImage...I don't recommend using JPEG for charts though, PNG will give you much better quality. Save JPEG for your photos...
