How to remove the border of an Icon in a JButton using Eclipse?

Question

first time making a question here. First of all, Eclipse (as far as I'm aware of) don't let you re dimension images through the design tab directly so to solve this I made a method that convert the icon from ImageIcon to image, re dimension it and then convert it back. The problem is that when I use the re dimensioned image it looks like this in a JButton.

I have already tried to create a emptyBorder in the JButton but that only remove the border of the button, not the icon. How can I remove it?

Edit: Just noticed that when the Window is not focused the border is not there? Image related

Answer 1

刚刚注意到当 Window 没有聚焦时，边框不存在？

button.setFocusPainted( false );
