Displaying images is a common requirement in graphical user interface (GUI) applications. With JavaFX, you can easily incorporate image display functionality into your Java applications. In this blog post, we will explore how to use JavaFX to display images.
This code creates a JavaFX application that displays an image of a duck, centered in a window:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class ImageDisplay extends Application {
private static final double WIDTH = 640;
private static final double HEIGHT = 480;
@Override
public void start(Stage stage) {
// Create a BorderPane layout manager to arrange elements
BorderPane layoutManager = new BorderPane();
// Create a scene using the layout manager and set its dimensions
Scene scene = new Scene(layoutManager, WIDTH, HEIGHT);
// Create an ImageView to display an image
ImageView imageView = new ImageView();
// Load and set the image to the ImageView
imageView.setImage(new Image("duck.png"));
// Add the ImageView to the center of the BorderPane
layoutManager.setCenter(imageView);
// Set the title of the application window
stage.setTitle("Displaying Images with JavaFX");
// Set the scene for the stage (window)
stage.setScene(scene);
// Center the window on the screen
stage.centerOnScreen();
// Show the application window
stage.show();
}
}When executed, the program above produces a window, as depicted in the image below. Well, the image might be different for you.
