The code to include this applet looks as follows:
<APPLET CODE="Bumps.class" WIDTH=200 HEIGHT=100>
<PARAM NAME=image VALUE="height.gif">
<PARAM NAME=radius VALUE=50>
<PARAM NAME=bumpHeight VALUE=30>
</APPLET>
The image tag defines what image to use. The brightness of each pixel in the image is used to determine the height of the bumps - white is highest, and black is lowest. The radius tag defines the size of the spotlight, and the bumpHeight tag specifies how high the bumps stick up.
