I'm making a Java Swing application that has the following layout (MigLayout):
[icon][icon][icon][....]
where icon = jlabel and the user can add more icons
When the user adds or removes icons, the others should shrink or grow.
My question is really straightforward: I have a JLabel which contains an ImageIcon; how can I resize this icon?
I found that there is a minor edit to this fix from trolologuy on the last line of code, you will need to implement a new ImageIcon to get the code to compile properly (Yes I know this is 10 years ago). I found this to be an easy fix for a one off issue, but Suken Shah and Mr. Polywhirl have a better fix overall.
ImageIcon imageIcon = new ImageIcon("./img/imageName.png"); // assign image to a new ImageIcon
Image image = imageIcon.getImage(); // transform it
Image newimg = image.getScaledInstance(120, 120, java.awt.Image.SCALE_SMOOTH); // scale it smoothly
ImageIcon newImageIcon = new ImageIcon(newimg); // assign to a new ImageIcon instance
