JavaFX large image crashes ImageView

[Jeff Higgins]

New to JavaFX.
Is my example code flawed?
Is there a problem with large images in JavaFX?
Something else?

I grab an example from the web:
<http://www.java2s.com/Code/Java/JavaFX/JavaFXImageZoomExample.htm>

I download and process a PDF file:
<http://optics.byu.edu/BYUOpticsBook_2013.pdf>

gs -sDEVICE=png16m -dNOPAUSE -dBATCH -dSAFER \
-r600 -dFirstPage=1 -dLastPage=1 \
-sOutputFile=001.png BYUOpticsBook_2013.pdf

This gives me a 5100 × 6600 pixel image.

I attempt to view the image:

import javafx.application.Application;
import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.beans.property.DoubleProperty;
import javafx.beans.property.SimpleDoubleProperty;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.ScrollEvent;
import javafx.stage.Stage;

/**

*/
public class ZoomExample extends Application {

private ImageView imageView = new ImageView();
private ScrollPane scrollPane = new ScrollPane();
final DoubleProperty zoomProperty = new SimpleDoubleProperty(200);

@Override
public void start(Stage stage) throws Exception {

zoomProperty.addListener(new InvalidationListener() {
@Override
public void invalidated(Observable arg0) {
imageView.setFitWidth(zoomProperty.get() * 4);
imageView.setFitHeight(zoomProperty.get() * 3);
}
});

scrollPane.addEventFilter(ScrollEvent.ANY,
new EventHandler<ScrollEvent>() {

@Override
public void handle(ScrollEvent event) {
if (event.getDeltaY() > 0) {
zoomProperty.set(zoomProperty.get() * 1.1);
} else if (event.getDeltaY() < 0) {
zoomProperty.set(zoomProperty.get() / 1.1);
}
}
});

imageView.setImage(new Image("file:///home/jeff/001.png"));
imageView.preserveRatioProperty().set(true);
scrollPane.setContent(imageView);

stage.setScene(new Scene(scrollPane, 400, 300));
stage.show();

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

I get stack trace:

But this works:
I just can't see the image because no scroll, etc.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class LoadImage extends Application {

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

@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Load Image");

StackPane sp = new StackPane();
Image img = new Image("file:///home/jeff/001.jpg");
ImageView imgView = new ImageView(img);
sp.getChildren().add(imgView);

Scene scene = new Scene(sp);
primaryStage.setScene(scene);
primaryStage.show();
}
}

I didn't use your image, I used a large JPEG I had (4128x2322). The
program compiled but when I ran it, it took several seconds to open the
window and had no image and no scrollpane. No errors either. I'm
barely JavaFX literate but I don't know what your problem is.

I got the scrollbars - along with the stacktrace and no image.
Thanks for the confirmation.

Shrugs.

Perhaps, see below.

Perhaps, see below.

In an answer at stackoverflow a certain José Pereda
helpfully pointed me to some resources.
<http://stackoverflow.com/questions/27840362/javafx-large-image-crash>

Perhaps there are problems with large images in JavaFX.
Perhaps my hardware is not up to the task.
Using the -Dprism.verbose=true switch, I see that I'm not able to use
hardware acceleration.

Do I really need all that?
I'm able to wrangle that image and more in Swing and SWT!

Prism pipeline name = com.sun.prism.es2.ES2Pipeline
Loading ES2 native library ... prism_es2
succeeded.
GLFactory using com.sun.prism.es2.X11GLFactory
(X) Got class = class com.sun.prism.es2.ES2Pipeline
Failed Graphics Hardware Qualifier check.
System GPU doesn't meet the es2 pipe requirement
Prism pipeline name = com.sun.prism.sw.SWPipeline

GraphicsPipeline.createPipeline: error initializing pipeline
com.sun.prism.es2.ES2Pipeline
*** Fallback to Prism SW pipeline

It's all too bad. I have a nice little Swing image annotation
application that I think would benefit from the JavaFX
scenegraph rather that my little homemade one but now it seems
I'll be unable to try it.

Boo hoo.
