如何在JavaFX中查看多个图像？
使用这些方法，可以在单个图像视图中设置多个图像。
示例
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import javafx.application.Application;
import javafx.geometry.Rectangle2D;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class ViewingMultipleImages 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 imageView1 = new ImageView(image);
//设置图像视图参数
imageView1.setX(10);
imageView1.setY(10);
imageView1.setFitWidth(200);
imageView1.setPreserveRatio(true);
ImageView imageView2 = new ImageView(image);
//设置图像视图参数
imageView2.setX(230);
imageView2.setY(10);
imageView2.setFitWidth(350);
imageView2.setPreserveRatio(true);
//设置视口
Rectangle2D rect2 = new Rectangle2D(45, 30, 250, 250);
imageView2.setViewport(rect2);
Image image2 = new Image(new FileInputStream("D:\\images\\boy.jpg"));
//创建图像视图
ImageView imageView3 = new ImageView(image2);
//设置图像视图参数
imageView3.setX(10);
imageView3.setY(200);
imageView3.setFitWidth(200);
imageView3.setPreserveRatio(true);
//设置场景对象
Group root = new Group(imageView1, imageView2, imageView3);
Scene scene = new Scene(root, 595, 370, Color.BEIGE);
stage.setTitle("Multiple Images");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]) {
launch(args);
}
}输出结果
