Cannot load image in JavaFX

Question

I tested this code in order to create dialog with image.

final int xSize = 400;
final int ySize = 280;
final Color backgroundColor = Color.WHITE;
final Strin         


        

Answer 1

Try this:

img = new Image("/logo.png");

If no protocol part indicating a URL (as http: or file:) is given, the file is supposed to reside in the default package. If you want it to put in a different package say com.my.images you add this information in a path like manner:

img = new Image("/com/my/images/logo.png");

Answer 2

This functions:

Image image  = new Image(getClass()
        .getResourceAsStream("ChimpHumanHand.jpg"));

Answer 3

Image img = new Image("file:/logo.png");

or way with path:

Image img = new Image("file:c:/logo.png");

or

File f = new File("c:\\logo.png");
Image img = new Image(f.toURI().toString());

also can use:

new Image(file:src/logo.png) //root of project

Answer 4

copy and paste the image into folder where source package(source packages in NetBeans IDE) is present. Then

Image image = new Image("a1.jpg");
Image image = new Image("File:a1.jpg");

both will work.

Answer 5

Simply replace this code:

Image img = new Image("logo.png");

with this

Image img = new Image("file:logo.png");

Docu reference. https://docs.oracle.com/javase/8/javafx/api/javafx/scene/image/Image.html

When you pass a String to the Image class it can be handled in four different ways (copied from docu):

// The image is located in default package of the classpath
Image image1 = new Image("/flower.png");

// The image is located in my.res package of the classpath
Image image2 = new Image("my/res/flower.png");

// The image is downloaded from the supplied URL through http protocol
Image image3 = new Image("http://sample.com/res/flower.png");

// The image is located in the current working directory
Image image4 = new Image("file:flower.png");

The file: prefix is simply an URI scheme, or in other words the counterpart to the http: protocol classifier. This also works in the file browser, or in the web browser... ;)

For further reference, you can take a look at the wiki page of the file URI scheme: https://en.wikipedia.org/wiki/File_URI_scheme
