Resizing JLabel ImageIcon With HTML
So I looked through this thread and saw the suggestion of using HTML for resizing. I've been going through the Oracle website but it only provided example for text customization in
Solution 1:
This basically requires you to have a URL reference to the image in question. This is quite easy to achieve if the image is an embedded resource (as demonstrated below), but you should be able to generate a URL from file using File#getURI#toURL
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.net.URL;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class HTMLLabel {
public static void main(String[] args) {
new HTMLLabel();
}
public HTMLLabel() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
URL url = getClass().getResource("/Chicken.png");
System.out.println(url);
JLabel perLabel = new JLabel("<html><img width=125 height=125 src=" + url + "></html>");
JLabel orgLabel = new JLabel("<html><img src=" + url + "></html>");
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
frame.add(orgLabel, gbc);
frame.add(perLabel, gbc);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
}
It should be noted that scaling is pretty redumentry. I would, personally, avoid it and simple devise some kind of ImagePane that had better scaling capabilities, for example
