I looked all over the place but I am still stuck on how directory works to find the image to put onto the JPanel. Where is the image supposed to be? I clicked on properties for my image and it shows Location: C:\Users\Joseph\Pictures\Background and the picture's name is random.jpg.
I am trying to add an image to a tab using tabbedPane. Here is what I have so far, and I am not able to do it.
JPanel flPanel = new JPanel();
flPanel.setLayout(new FlowLayout());
ImageIcon image = new ImageIcon(getClass().getResource(""));
// Tried /Users/Joseph/Pictures/Background/random.jpg and doesn't work
JLabel j1 = new JLabel(image);
flPanel.add(j1);
tabbedPane.add("Tab 2", flPanel);
Is the picture supposed to be in the same package file as the project? Or is it supposed to be in the source file to be able to just do "random.jpg"?
If you want the image to be available to your application at runtime, then you should consider making sure that the image is included within your Jar when you application is built.
From the sounds of it, you are using Netbeans, you should copy the image to a directory within your src directory of your project.
You should then be able to use...
BufferedImage bi = ImageIO.read(getClass().getResource("/full/path/to/image/random.jpg"));
ImageIcon image = new ImageIcon(bi);
The path to the image should be the full path (from the context of the src directory) within your project.
That is, if you placed the image in the resources directory within the src directory, then you would use /resources/random.jpg as the path/file name
Take a look at Reading/Loading an Image for more details
getClass().getResource(...) will only get resources inside the classpath.
You can use ImageIO.read(File) like this:
BufferedImage bi = ImageIO.read(new File("C:\\Users\\Joseph\\Pictures\\Background\random.jpg"))
ImageIcon image = new ImageIcon(bi);

I have a frame and want to set an icon for it. I use this code : JFrame f = new JFrame(); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setLayout(null); f.setTitle("add icon example"); f.setBounds(200,200,200,200); Image icon = Toolkit.getDefaultToolkit().getImage("D:\\icon.png"); f.setIconImage(icon); f.setVisible(true); In this code , the address of image is specific , but what can I do if image and jar file are in a zip file and icon will be with jar file. I think I can write a code to unzip the file and then save the image in a specified address and then use it. But , please anyone help me to do it. Thanks.
The answer is something like
BufferedImage im = ImageIO.read(myClass.getResourceAsString("iconName"));
If you're trying to load an image that's within a JAR, this is the most simple approach to this problem. This will also work if your jar is executed from within a zip archive.
BufferedImage image = ImageIO.read(MyClass.class.getClassLoader().getResourceAsStream("image_name.png"));
Where MyClass is the name of the class you're calling this code from.
I am creating a simple GUI using swing in Java and simply want to display a JPEG image as a banner in the frame. I have the image working properly, but the filepath is subject to change as this will be sent to other people. The image is stored in the folder I will be sending to others. I am looking for a way to ensure that no matter what location the the folder has been moved to, the image will display. I am new to this site, and fairly new to Java. Thanks for you help in advance.
Relevant Code:
ImageIcon numberImage = new ImageIcon("C:\\Users\\Me\\Desktop\\numberGame\\numbers.jpg");
Image image = numberImage.getImage();
Image newimg = image.getScaledInstance(300,120,java.awt.Image.SCALE_SMOOTH);
numberImage = new ImageIcon(newimg);
JLabel imageLabel = new JLabel("", numberImage, JLabel.CENTER);
JPanel imagePanel = new JPanel(new BorderLayout());
imagePanel.add(imageLabel, BorderLayout.CENTER );
To ensure, the image could be displayed in every context, you must specify a relative path instead of an absolute path.
You could change:
ImageIcon numberImage = new ImageIcon("C:\Users\Me\Desktop\numberGame\numbers.jpg");
To:
ImageIcon numberImage = new ImageIcon("numbers.jpg");
And this should work in other contexts (with other different paths).
Or if the image is in a directory inside your program put "\imageFolder\numbers.jpg".
This should work, the main change is to replace the absolute path with a relative path.
You want to use a relative path instead of absolute. Here's a quick explanation that's pretty clear.

Good luck. :)
I am trying to upload an image on a GUI. Here is what my code reads right now:
ImageIcon icon = new ImageIcon(nameSearched.getImage());
myLabelK = new JLabel();
myLabelK.setBounds(500,100,200,200);
myLabelK.setIcon(icon);
myPanel.setLayout(null);
myPanel.add(myLabelK);
Validate();
add(myPanel);
setVisible(true);
When I run my program this image is not popping up on my GUI.
The nameSearched.getImage() is calling a method in a different class which returns an image entered into the system. For example, Peter.jpg.
Please help me figure out how to get my image on the screen.
If you are just using Peter.jpg as you relative path name,
Using an IDE, you image should be ditrectly below the ProjectRoot directory
ProjectRootDir
Peter.jpg
src
If you wanted to have your image in an images folder:
use "images\Peter.jpg"
ProjectRootDir
images
Peter.jpg
src
Maybe you want to retrieve the image like this
ImageIcon icon = new ImageIcon("Peter.jpg");
Another possibility, If you do this:
ImageIcon icon = new ImageIcon(nameSearched.getImage());
then nameSearched.getImage() must return either a String fie path of the image
or an Image object.
Maybe you just want nameSearched.getImage() to return a String from an array of String paths. Not sure what nameSearched.getImage() actually does so I can't go into further explanation or correction
i have a the path of an image in a string i want to display it on a jlabel using the path. please help me.
if(!ar.get(16).equals("empty")){
String photo=(String)ar.get(16);
System.out.println(photo);
// if(!photo.equals(""))
// pic.setText(photo);
Image image=Toolkit.getDefaultToolkit().getImage(photo);;
ImageIcon img=new ImageIcon(image.getScaledInstance(view.jLabel5.getWidth(), view.jLabel5.getHeight(), 0));
//JpegReader jrdr=new JpegReader();
//view.jLabel5.setSize(img, image.getWidth());
view.jLabel5.setPreferredSize(new Dimension(100, 100));
view.jLabel5.setIcon(img);
}
If the image is an embedded resources (ie lives within the application context/is bundled with the application Jar), then you need to use getResource to gain access to it..
Toolkit.getDefaultToolkit().getImage expects that the String passed to it is a file on the file system.
If the image is embedded, then you will need to use something more like...
Toolkit.getDefaultToolkit().getImage(getClass().getResource(photo))
To load it.
If the image is being loaded from the file system, you could use
File file = new File(photo);
if (file.exists()) {
// Attempt to load the image
} else {
// Show error message.
}
Because of the way Toolkit#getImage works, it will not provide any details if the image fails to load for some reason.
Instead, you should be using ImageIO, which will throw an IOException if it was unable to load the image for some reason...
BufferedImage img = ImageIO.read(getClass().getResource(photo));
or
BufferedImage img = ImageIO.read(new File(photo));
Depending on where the image is located.
Take a look at Reading/Loading an Image.
You should also avoid calling setPreferredSize explicitly and simply allow JLabel to make it's own choices...
Put the image file in the project. Under a seperate folder.
ImageIcon image = new ImageIcon(this.getClass().getResource("/images/abc.jpg"));
JLabel imageLabel = new JLabel(image, JLabel.CENTER);
If you want to load the image for any other location on your computer then,
ImageIcon image = new ImageIcon("C:/images/image.png");
JLabel imagelabel = new JLabel(image);
Make sure your paths are correct. If you photo string path is "photo.jpeg", your path should look something like this
ProjectRoot
photo.jpeg
src
If you want to put the photo.jpeg in a directory images, you should use "images/photo.jpeg"
ProjectRoot
images
photo.jpeg
src
This is considering you're using an IDE like Netbeans or Ecplise.
I am having difficulty creating the image icon. I want to package a jar and have the images available to be displayed in the gui. Both of the following throw null pointer exceptions. The path is a path directly to a package in my Eclipse project that contains the necessary images.
ImageIcon icon = new ImageIcon(this.getClass().getClassLoader().getResource(
"/TicTacToe/src/edu/luc/tictactoe/gui/resources/images/TicTacToeOIcon.png")
.getPath());
and
ImageIcon icon = new ImageIcon(getClass().getResource(
"/TicTacToe/src/edu/luc/tictactoe/gui/resources/images/TicTacToeOIcon.png"));
I can't see to be able to access the appropriate package. Any suggestions?
ImageIcon icon = new ImageIcon(this.getClass().getClassLoader()
.getResourceAsStream("edu/luc/tictactoe/gui/resources/images/TicTacToeOIcon.png");
Try like this
JButton myButton =new JButton(“press me”);
myButton.setIcon(new ImageIcon(image));
EDIT:
Refer to this discussion to know loading the image from executable Jar files
