Hi i'm using JavaFx WebView to create Screenshot of HTML pages and it works fine but i wanted to know is it possible to do this without launching the application in Graphical Windows!! I mean aren't there any more lightweight method to get the screenshot then this:
public class WebViewSample extends Application {
private Scene scene;
@Override
public void start(Stage stage) {
// create scene
scene = new Scene(new Browser(snapshot), 750, 500, Color.web("#666970"));
stage.setScene(scene);
// show stage
stage.show();
}
WritableImage snapshot;
public static void main(String[] args) {
launch(args);
System.err.println("launched!");
}
}
class Browser extends Region {
final ImageView selectedImage = new ImageView();
final WebView browser = new WebView();
final WebEngine webEngine = browser.getEngine();
private final WritableImage snapshotImage;
public Browser(WritableImage snapshot) {
this.snapshotImage= snapshot;
// process page loading
webEngine.getLoadWorker().stateProperty().addListener(
new ChangeListener<State>() {
@Override
public void changed(ObservableValue<? extends State> ov,
State oldState, State newState) {
if (newState == State.SUCCEEDED) {
WritableImage newSnapshot = browser.snapshot(null, snapshotImage);
File file = new File("test2.png");
RenderedImage renderedImage = SwingFXUtils.fromFXImage(newSnapshot, null);
try {
ImageIO.write(renderedImage, "png", file);
} catch (IOException e1) {
e1.printStackTrace();
}
System.exit(0);
}
}
}
);
// load the home page
webEngine.load("http://localhost/");
//add components
getChildren().add(browser);
}
}

For JavaFX 2.2 and below, there's not functionality of the kind.
Headless JavaFX applications are currently not possible, and a main JavaFX thread is mandatory.
The best you can do is read upon several workarounds for achieving this.
