Re: converting display to jpeg or gif file

Using the the visad.util.Util.captureDisplay(DisplayImpl disp, String
filename)  routine seems a heck of a lot simpler than the way I was informed
when I had a similar question several months back.  Is the captureDisplay
utility new???  I did the following in my code.

Luke


 public void captureDialog(String file) {
        final File f = new File(file);
        if (f == null) return;
        Runnable captureImage = new Runnable() {
            public void run() {
                String msg = "Could not save image snapshot to file \"" +
f.getName() +
                "\" in JPEG format. ";
                    saveAsJPEG(f);
            }
        };
        Thread t = new Thread(captureImage);
        t.start();
    }

void saveAsJPEG(File f) {
        BufferedImage image = display.getImage();
        FileOutputStream fout;
        try {
            JPEGEncodeParam param
JPEGCodec.getDefaultJPEGEncodeParam(image);
            param.setQuality((float)1.0, true);
            fout = new FileOutputStream(f);
            JPEGImageEncoder encoder =JPEGCodec.createJPEGEncoder(fout);
            encoder.encode(image, param);
           fout.close();
        }
        catch (RemoteException err) {
        }
        catch (FileNotFoundException err) {
        }
        catch (IOException err) {
        }
  }
