Display moving image in Java Swing

Question

I\'m trying to display a high-width image in Java Swing (say 2000x100, like a heart rate strip). I need to show only a window of 500 width while it is slightly moving toward

Answer 1

The end of image should be concatenated with the beginning of the image. So it always repeats showing

Check out the Marquee Panel. You can add a JLabel with an ImageIcon to the MarqueePanel.

The MarqueePanel provides various method to customize the scrolling.

Edit:

The basic code would be:

MarqueePanel panel = new MarqueePanel();
panel.setWrap(true);
panel.setWrapAmount(0);
panel.setPreferredWidth(250);

JLabel label = new JLabel( new ImageIcon( "heartbeat.jpg" ) );
panel.add( label );

frame.add( panel );

If you want the image to fully appear at the left when it is displayed you can change the startScrolling() method and use scrollOffset = 0;.
