I'm trying to edit five images I have in a folder at once (using javafx motion blur), rather than select them one after the other. This is my code, I'm not exactly sure what I'm doing wrong but when I run it, only the last image in the folder gets edited. The others remain as they are.
public class IterateThrough extends Application {
private Desktop desktop = Desktop.getDesktop();
#Override
public void start(Stage primaryStage) throws IOException {
File dir = new File("filepath");
File [] directoryListing = dir.listFiles();
if (directoryListing != null) {
for (File file : directoryListing) {
if(file.getName().toLowerCase().endsWith(".jpeg")){
//desktop.open(file);
Image image = new Image(new FileInputStream(file));
//Setting the image view
ImageView imageView = new ImageView(image);
//setting the fit height and width of the image view
imageView.setFitHeight(600);
imageView.setFitWidth(500);
//Setting the preserve ratio of the image view
imageView.setPreserveRatio(true);
// instantiate Motion Blur class
MotionBlur motionBlur = new MotionBlur();
// set blur radius and blur angle
motionBlur.setRadius(15.0);
motionBlur.setAngle(110.0);
//set imageView effect
imageView.setEffect(motionBlur);
//Creating a Group object
Group root = new Group(imageView);
//Creating a scene object
Scene scene = new Scene(root, 600, 500);
//Setting title to the Stage
primaryStage.setTitle("Loading an image");
//Adding scene to the stage
primaryStage.setScene(scene);
//Displaying the contents of the stage
primaryStage.show();
}
}
}
}
public static void main(String[] args) {
launch(args);
}
}
first, you shouldn't just let the primaryStage show() in the for-each loop, because when the primaryStage first show(), the fx thread pause on that instruction, the remaining pictures will not be read and when you close the window, the loop won't continue to go on for remaining, it represents the end of the application.
so it's better to let the primaryStage show() outside the each-loop after all image has been read.
second, you shouldn't use the "Group" container to contains all images, better use VBox/HBox/FlowPane, make sure above image won't covers below's.
here's modified code for reference.
public class IterateThrough2 extends Application{
private Desktop desktop = Desktop.getDesktop();
#Override
public void start(Stage primaryStage) throws IOException{
File dir = new File("filepath");
File[] directoryListing = dir.listFiles();
FlowPane root = new FlowPane();
if(directoryListing != null){
for(File file : directoryListing){
if(file.getName().toLowerCase().endsWith(".jpeg")){
Image image = new Image(new FileInputStream(file));
ImageView imageView = new ImageView(image);
imageView.setFitHeight(600);
imageView.setFitWidth(500);
imageView.setPreserveRatio(true);
MotionBlur motionBlur = new MotionBlur();
motionBlur.setRadius(15.0);
motionBlur.setAngle(110.0);
imageView.setEffect(motionBlur);
root.getChildren().add(imageView);
}
}
}
Scene scene = new Scene(root, 600, 500);
primaryStage.setTitle("Loading an image");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args){
launch(args);
}
}

I have a stationary image and would like to play various MP4 clips on top of this image with some level of transparency. are there any examples for this in Java. I attempted JavaFX and can play the video but I need the image to be present (visible) at all times then I would like to play the video clips on top of the image. any suggestions/examples? I have code from an example but it only plays the video. I need to start with a still image then play the video on top with some transparency:
enter code here
public static void main(String[] args) throws Exception{
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
//goes to user Directory
File f = new File("c:\\tpd\\video.mp4");
Image background = new Image(new
FileInputStream("c:\\tpd\\Image.jpg"));
//Converts media to string URL
Media media = new Media(f.toURI().toURL().toString());
player = new javafx.scene.media.MediaPlayer(media);
MediaView viewer = new MediaView(player);
//change width and height to fit video
DoubleProperty width = viewer.fitWidthProperty();
DoubleProperty height = viewer.fitHeightProperty();
width.bind(Bindings.selectDouble(viewer.sceneProperty(), "width"));
height.bind(Bindings.selectDouble(viewer.sceneProperty(), "height"));
viewer.setPreserveRatio(true);
ImageView foreground = new ImageView(background);
viewer.setOpacity(.6f);
StackPane root = new StackPane();
root.getChildren().addAll(foreground,viewer);
Scene scene = new Scene(root,1920, 1080, Color.BLACK);
stage.setAlwaysOnTop(true);
stage.setScene(scene);
stage.setTitle("myVideo");
stage.show();
player.play();
}
I have a code written using javafx and java 11. As I showed in the below code snippet, when I move my ImageView to right of the scene, The ImageView disappears.
At first:
and then after moving it using arrow keys with the help of scene event listener:
then:
and finally:
I don't use fxml. Here is my demo which has the problem too.
public class HelloApplication extends Application {
public String fetchResource(String path) {
return Objects.requireNonNull(getClass().getResource(path)).toString();
}
#Override
public void start(Stage stage) throws IOException {
Rectangle r = new Rectangle(100, 100);
ImageView spaceShip = new ImageView(fetchResource("spaceShip.png"));
spaceShip.setFitHeight(100);
spaceShip.setFitWidth(100);
spaceShip.setX(0);
spaceShip.setY(0);
EventHandler<KeyEvent> keyListener = event -> {
if (event.getCode() == KeyCode.RIGHT) {
spaceShip.setX(spaceShip.getX() + 20);
}
};
Group game = new Group(spaceShip);
Scene scene = new Scene(game, 1840, 1080);
scene.setOnKeyPressed(keyListener);
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
I should mention that I create a rectangle and check the scenario with that, And there was not any problem. I think there is some problem with ImageView.
I couldn't reproduce the issue with your code, but I could with SceneBuilder. You may get the desired result if you wrap the Group in a Pane (at least it works in SceneBuilder).
Group game = new Group(spaceShip);
Pane pane = new Pane(game);
Scene scene = new Scene(pane, 1840, 1080);
stage.setScene(scene);
stage.show();
I'm trying to put an image as a background in a JavaFX scene, but my code isn't working.
Im trying to make a Battleship-game program in java eclipse but i'm stuck at a graphics problem.
public class WindowGUI extends Application{
Game game;
Image image;
public WindowGUI(Game game) {
this.game = game;
}
public static void main(String[] args) {
Game game = new Game();
new WindowGUI(game);
}
#Override
public void start(Stage stage) throws Exception {
stage.setTitle("Battleship");
image = new Image ("C:\\Users\\amali\\git\\inf101.v19.sem2\\inf101.v19.sem2\\src\\window\\battleshipbackground.jpg");
ImageView background = new ImageView(image);
Button startButton = new Button("START");
BorderPane newStack = new BorderPane();
newStack.getChildren().add(startButton);
newStack.getChildren().add(background);
stage.setScene(new Scene(newStack, 1300, 860));
stage.show();
startButton.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
// START THE GAME
}
});
}
}
When I first tried to run it, it worked and a new window opened with a button in the center, but the bakcground was blank. When i try setting an image as background in the window, behing the 'start'-button, nothing happens..
A better way to do it is to use the Background class rather than trying to add an ImageView as a child of your BorderPane.
Image image = new Image("C:\\Users\\amali\\git\\inf101.v19.sem2\\inf101.v19.sem2\\src\\window\\battleshipbackground.jpg");
BackgroundSize size = new BackgroundSize(BackgroundSize.AUTO,
BackgroundSize.AUTO,
false,
false,
true,
false);
Background background = new Background(new BackgroundImage(image,
BackgroundRepeat.NO_REPEAT,
BackgroundRepeat.NO_REPEAT,
BackgroundPosition.CENTER,
size));
newStack.setBackground(background);
Use BackgroundImage class.

JavaFX How to set scene background image
I was trying to display a picture in a box with JavaFX. I followed methods documented on Oracle, but it still did not work, though it was extremely similar to the example shown on Oracle. My code is here:
public class TesterJavaFX extends Application {
#Override
public void start(Stage primaryStage) {
Image img = new Image("character.png");
ImageView imgview = new ImageView();
imgview.setImage(img);
imgview.setFitWidth(100);
imgview.setPreserveRatio(true);
imgview.setSmooth(true);
imgview.setCache(true);
HBox box = new HBox();
box.getChildren().add(imgview);
StackPane root = new StackPane();
root.getChildren().add(box);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**

I have a file called rocket.png in the "src" directory. It even shows up on the IDE. But Java causes a illegal argument exception, and i don't know why. Can anybody help me? Thanks.
Note: The imports are all present.
The string passed to the Image constructor is a URL. If the image file is in the root of your classpath, the following should work:
Image img = new Image(getClass().getResource("/character.png").toExternalForm());
I have a TilePane with a imageView items, each imageview displaying an image got from a directory in my pc. When any of the images in the tilePane is clicked a message is printed onto console with the direcory path address to the folder where the image resides, for example:
You clicked: ImageResources/wp.png
I would like to extend this further so that when a particular image is clicked the folder in which the image resides opens.
My implementation below only prints to console the message below, but no directory/ folder gets opened. The message is:
File Not Found
How can I get it to work so that the folder|directory opens? Thank you all in advance.
Also, of the directory could open with the clicked image selected, then that would be an extra, but is not a priority right now.
My implementation so far goes as follows:
public class TilePaneExample extends Application {
#Override
public void start(Stage primaryStage) {
VBox root = new VBox(30);
String[] imageResources = new String[]{
//loading images
"ImageResources/facebook.png",
"ImageResources/faviicon.png",
"ImageResources/jquery-logo.png",
"ImageResources/linkedin_32.png",
"ImageResources/loading1.png",
"ImageResources/twitter.png",
"ImageResources/twitter_32.png",
"ImageResources/wp.png",};
// Pane
TilePane tilePane = new TilePane();
tilePane.setHgap(5);
tilePane.setVgap(5);
for (final String imageResource : imageResources) {
Image image = new Image(getClass().getResourceAsStream(imageResource));
ImageView imageView = new ImageView(image);
imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
File f = new File(imageResource);
String absolutePath = f.getAbsolutePath();
String folderPath = absolutePath.
substring(0, absolutePath.lastIndexOf(File.separator));
try {
Desktop.getDesktop().open(new File(folderPath));
} catch (IllegalArgumentException iae) {
System.out.println("File Not Found");
} catch (IOException ex) {
Logger.getLogger(TilePaneExample.class.getName()).log(Level.SEVERE, null, ex);
}
}
});
tilePane.getChildren().add(imageView);
}
root.getChildren().addAll(tilePane);
primaryStage.setTitle("TilePane Example");
Scene scene = new Scene(root, 300, 150);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
For example, clicking the second image, "ImageResources/faviicon.png", prints its folder path as D:\standAloneDev\java\workingDir\Jive\TilePaneExample\ImageResources
