如何在JavaFX中显示图像？
例
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.stage.Stage;
public class ImageViewExample extends Application {
public void start(Stage stage) throws IOException {
//创建图像对象
InputStream stream = new FileInputStream("D:\\images\\elephant.jpg");
Image image = new Image(stream);
//创建图像视图
ImageView imageView = new ImageView();
//将图像设置为图像视图
imageView.setImage(image);
//设置图像视图参数
imageView.setX(10);
imageView.setY(10);
imageView.setFitWidth(575);
imageView.setPreserveRatio(true);
//设置场景对象
Group root = new Group(imageView);
Scene scene = new Scene(root, 595, 370);
stage.setTitle("Displaying Image");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]) {
launch(args);
}
}输出结果
