public class CountdownCanvas

extends java.awt.Canvas

implements java.awt.image.ImageObserver

Shows the CountdownDigits when animation is switched on, or the current date and the remaining days if it is switched off. This canvas also knows all the colors for the fade (which may save some time on creating and using colors that are usually repeatedly used).

Since:

JDK1.1

Version:

1.0
