TranslucentPane.java

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.image.*;
import javafx.scene.layout.*;
import javafx.stage.Stage;

public class TranslucentPane extends Application {
  @Override public void start(final Stage stage) throws Exception {
    final ImageView imageView = new ImageView(
      new Image("http://upload.wikimedia.org/wikipedia/commons/b/b7/Idylls_of_the_King_3.jpg")
    );
    imageView.setFitHeight(300);
    imageView.setFitWidth(228);

    final Label label = new Label("Camelot");
    label.setStyle("-fx-text-fill: goldenrod; -fx-font-style: italic; -fx-font-weight: bold; -fx-padding: 0 0 20 0;");

    StackPane glass = new StackPane();
    StackPane.setAlignment(label, Pos.BOTTOM_CENTER);
    glass.getChildren().addAll(label);
    glass.setStyle("-fx-background-color: rgba(0, 100, 100, 0.5); -fx-background-radius: 10;");
    glass.setMaxWidth(imageView.getFitWidth() - 40);
    glass.setMaxHeight(imageView.getFitHeight() - 40);

    final StackPane layout = new StackPane();
    layout.getChildren().addAll(imageView, glass);
    layout.setStyle("-fx-background-color: silver; -fx-font-size: 20; -fx-padding: 10;");
    stage.setScene(new Scene(layout));
    stage.show();
  }

  public static void main(String[] args) { launch(args); }
