This page consists of a series of examples to demonstrate the use of the AniS applet for making animations and overlays. Subsequent pages deal with portals, and more complex combinations.
Each example illustrates one or more of the features of this applet, and are designed to provide an example of the HTML needed to obtain results.
The overall goal of this project was to give you, the web page author, a toolkit for using combinations of several different techniques that have been developed in support of projects using satellite images.
1a. The "almost" simplest form: animate a series of images. Just allow the users to stop and start the animation. (The "very simplist" form would have no controls...but I thought that was too boring!) The complete applet tag is:
1b. The "other" simplest form: fade between a series of images. Just allow the users to alter the fading among the 3 images. The Applet's parameters are the same as 1b, except the for the controls:
2. Now lets treat those same images as faded animations by adding a start/stop control. We'll add the zoom control, too. We just need to add a "zoom" to the controls parameter:
3. Now we want to give them controls for speed and stepping the frames (we'll go back to the un-faded 3 frames for this example, though, by removing the PARAM for the "fade"). The new controls PARAM looks like:
4. Using overlays. In order to use overlays, you must provide four pieces of information:
5. Now let's animate the background. You need only add more filenames>
6. You may also want to add on - off controls so that the user can remove frames if they want. This is done by adding the name onoff to the list of controls:
