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) {
}
}
