使用JFileChooser将文件插入Jlabel

Question

Am trying to get a file(image) to fit into a Jlabel with JFileChooser. But it enlarges the Jlabel when i insert the file.
This is a sample of my codes...

JFileChooser chooser = new JFileChooser();
chooser.showOpenDialog(null);
File f = chooser.getSelectedFile();
String filename = f.getAbsolutePath();
btnInsert.setText(filename);
ImageIcon icon = new ImageIcon(filename);
lblPic.setIcon(icon);

Try this code, it may helpful to you.

Read the picture as a BufferedImage

 BufferedImage img = null;
 JFileChooser chooser = new JFileChooser();
 chooser.showOpenDialog(null);
 File file = chooser.getSelectedFile();
 try {
     img = ImageIO.read(file );
 } catch (IOException e) {
     e.printStackTrace();
 }

Resize the BufferedImage

Image dimg = img.getScaledInstance(label.getWidth(), label.getHeight(), Image.SCALE_SMOOTH);

Make sure that the label width and height are the same proportions as the original image width and height. In other words, if the picture is 600 x 900 pixels, scale to 100 X 150. Otherwise, your picture will be distorted.

ImageIcon imageIcon = new ImageIcon(dimg)
