Chart

public class Imagemap
extends Image

An image map.

There are two ways to use Imagemap:

1. Listen to the onClick event, which is an instance of MouseEvent. Then, you could call getX() and getY() to retrieve where user has clicked.
2. Assign one or multiple of Area as its children. Then, listen to the onClick event, and use MouseEvent.getArea() to retrieve which area is clicked.

Note: IE 5.5/6 (not 7) has a bug that failed to render PNG with alpha transparency. See http://homepage.ntlworld.com/bobosola/index.htm for details. Thus, if you want to display such image, you have to use the alphafix mold. <imagemap mold="alphafix"/>
