Apparently, this is my code I have been using to get image from my disks to my program.
public void getVehicleImage(){
FileDialog fd = new FileDialog(this);
fd.setFile("*.jpg; *.jpg; *.png; *.gif");
fd.show();
vehicle_path = fd.getDirectory()+fd.getFile();
vehicleFileName.setText(vehicle_path = fd.getFile());
vehicleImagePath.setText(vehicle_path = fd.getDirectory()+fd.getFile());
image.setIcon(new ImageIcon(vehicle_path));
}
How do I fit the image to the size of my jLabel? I have tried using the
getScaledInstance()
but still no good. And also I want to ask if I am using the right code on how to get Image from my disk? I kinda feel it is wrong.
I faced similar problem and did below workaround:
Step1: Read the picture as a BufferedImage from your file system.
BufferedImage image = null;
try {
image = ImageIO.read(new File("fileName.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
Step2: Create a new BufferedImage that is the size of the JLabel
BufferedImage img= image.getScaledInstance(label.width, label.height,
Image.SCALE_SMOOTH);
Step3: Create new ImageIcon from the resized BufferedImage (Step 2)
ImageIcon imageIcon = new ImageIcon(img);
In your case, create a helper method and call it while creating ImageIcon as below:
public void getVehicleImage(){
...................
image.setIcon(new ImageIcon(getScaledImage(vehicle_path)));//call helper here
}
This can be helper function:
public BufferedImage getScaledImage(String imagePath){
BufferedImage image = null;
try {
image = ImageIO.read(new File("fileName.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
BufferedImage img= image.getScaledInstance(label.width, label.height,
Image.SCALE_SMOOTH);
return img;
}

I want to read the full path of an image located in my package to scale it so the image can fit my JLabel, however, everytime I compile my code the following error is produced:
javax.imageio.IIOException: Can't read input file!
at javax.imageio.ImageIO.read(Unknown Source)
Code:
public void loadImage(){
BufferedImage img = null;
try {
img = ImageIO.read(new File("/myPackage/image.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
BufferedImage dimg = (BufferedImage) img.getScaledInstance(lblImage.getWidth(), lblImage.getHeight(),
Image.SCALE_SMOOTH);
ImageIcon imageIcon = new ImageIcon(dimg);
lblImage.setIcon(imageIcon);
contentPane.add(lblImage);
}
Thanks in advance! :)
I would like to use an image as the background of a JPanel.
It needs to be loaded from a relative file path.
private void createBackground() {
try {
BufferedImage backgroundImage = ImageIO.read(new File("C:/Users/Developer/workspace/Java/BSC_Project/Application/src/resources/background.jpg"));
JLabel background = new JLabel(new ImageIcon(backgroundImage));
this.add(background);
} catch(IOException e) {
System.out.println(e.toString());
}
}
My current code is not working. Any help would be appreciated.
So can't comment(need 50 rep) but your file path is completely wrong
you need it to be something like this
new File("C:/Users/"Insert Username"/Desktop/workspace/Java/BSC_Project/Application/src/resources/background.jpg")
except I'm not on your computer so you need to figure out your own file path, This would be assuming your workspace folder is on your Desktop which it almost certainly isn't, do you understand?
Well if you want your code to have a panel this is what you would do...
private void createBackground() {
try {
BufferedImage backgroundImage = ImageIO.read(new File("C:/Users/Developer/workspace/Java/BSC_Project/Application/src/resources/background.jpg"));
JPanel panel = new JPanel();
JLabel background = new JLabel(new ImageIcon(backgroundImage));
panel.add(background);
this.add(panel);
} catch(IOException e) {
System.out.println(e.toString());
}
}
but in your case it looks to me like you want a frame background as image... to which you can set the image background to which for that one you can try this code
JFrame f = new JFrame ("SettingBackGround");
try{
f.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("Med.jpg")))));
}catch (IOException e){
System.out.println("Image Doesnt Exist");
}
f.setVisible(true);
f.setResizable(false);
f.pack();
}
}
I hope this helps though.
public WelcomeView() {
initComponents();
try {
image = ImageIO.read(new File("C:\\Users\\Developer\\workspace\\Java\\BSC_Project\\Application\\src\\application\\resources\\background.png"));
} catch (IOException ex) {
System.err.println(ex.toString());
}
}
private BufferedImage image;
#Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 2, 0, null); // see javadoc for more info on the parameters
}
I've got a simple swing application with a JFrame that holds various components. On the JFrame I have a custom toolbar class that extends JPanel. On the JPanel I plan on adding buttons with image icons. My directory structure is as follows:
Project/src/gui (Package holds source files for application)
Project/src/images (Package holds a jar file jlfgr-1_0.jar with button icons and /or individual images files)
The issue is that I want to avoid copying the individual image files to the images package. I'd rather somewhow just load the images directly from the jar file. I've got private method that returns the appropriate icon. This method works, for example if I drag an image file to the images package and call:
button.setIcon(createIcon("/images/Save16.gif"));
private ImageIcon createIcon(String path) {
URL url = getClass().getResource(path);
ImageIcon icon = new ImageIcon(url);
if(url == null) {
System.err.println("Unable to load image: " + path);
}
return icon;
I know this is basic, but how can I get my images directly from the jar file in my current setup?
Thanks.
You can read the image from the stream, thanks to javax.imageio.ImageIO:
private ImageIcon createIcon(String path) {
BufferedImage image = ImageIO.read(getClass().getResourceAsStream(path));
ImageIcon icon = new ImageIcon(image);
return icon;
}
This is another way. The images are at location src/images
BufferedImage myPicture = null;
try {
myPicture = ImageIO.read(this.getClass().getResource("images/Picture2.png"));
} catch (IOException e) {
// TODO Auto-generated catch block
try {
myPicture = ImageIO.read(this.getClass().getResource("images/broken_image.jpg"));
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
JLabel picLabel = new JLabel(new ImageIcon(myPicture));
panel.add(picLabel);
I imported an image into Eclipse, in the same package as this class:
public class mainWindow extends JFrame {
public mainWindow() {
Image bg = // \mainPackage\ShittyPlane.png;
Graphics2D g2d;
this.setSize(500,500);
this.setResizable(false);
this.setTitle("GameTest");
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
g2d.drawImage(bg, 0, 0, null);
}
}
How do I define the image path?
If the image is part of you source and is packed into jar later for distribution i would sucgest you get a stream to the image using getResourceAsStream.
ClassLoader cl = getClass().getClassLoader();
InputStream is = cl.getResourceAsStream("mainPackage/ShittyPlane.png");
BufferedImage image = ImageIO.read(is);
this aproache will also work in if you run the program from your IDE
If you plan to locate the image using a a File chooser then go with #Pescis's answer.
What you need to do to load an image from a specific file is:
BufferedImage img = null;
try {
img = ImageIO.read(new File("src/mainPackage/ShittyPlane.png")); //I'm guessing this is the path to your image..
} catch (IOException e) {
}
For more info you can read the javadoc on working with images.
How can I convert a BufferedImage to an ImageIcon?
I can not find any documentation on this.
Use constructor: ImageIcon(Image image), BufferedImage extends Image.
BufferedImage extends Image, so it's simply:
new ImageIcon(myBufferedImage);
File img = new File("C:\\..\\image.jpg");
BufferedImage bufferedImage = ImageIO.read(img);
ImageIcon imageIcon = new ImageIcon(bufferedImage);
your bufferimage;
JLabel photo = new JLabel("Photo");
photo.setIcon(new ImageIcon(bufferimage));
here is a simple converter:
//Your icon
private ImageIcon icon;
//Your image
private BufferedImage image;
public void bufferImageTocon(){
File file = new File("test.jpg");
try {
this.image = ImageIO.read(file);
} catch (IOException ex) {
ex.printStackTrace();
}
icon = new ImageIcon(image);
}
Use just the constructor to make a new icon, setting the buffered image as a parameter.
