Greetings!

We hope you are here because you've heard great things about AniS or its predecessor, Ani2. The AniS applet has derived mainly from work done for the VISIT projects' VISITview collaboration and distance learning tool.

AniS is a Java (not JavaScript!) applet for animating images over the web (through browsers). It is not a stand-alone application for image animation. Information about the HTML <APPLET> tag is available here

If your users have questions or issues running Java applets (not just AniS), you might refer them to this information for help.

AniS has most of display features of VISITview, plus a few extras!, but you, as the Web site developer, specify (in the HTML) just what controls will be presented to the user for your specific application.

Important note about using the Java Plug-in If you or your users have installed the Java Plug-in to use with their browsers, please alert them to the necessity of adding a "Java Runtime Option" using the plug-in setup program - especially if they get an OutOfMemory Error. Please click here for the details.

Update information is now available by clicking here.

What can AniS do?

Examples

We've prepared several pages of examples that will give you the feeling for what's possible, and start to introduce the HTML needed to run AniS. Please take a look -- the examples start here and there are links at the bottom of each page to the next one! Or, you can just click on a particular example from this list:

Information about the using the HTML <APPLET> tag is available here

Detailed documentation

There is also a detailed document that defines each parameter.

This document also contains tips on deploying AniS with dynamic web pages, and how to avoid having multiple copies of the class files on your server when you have several animations set up.

How to get the software

  1. Download this ZIP file, which contains only the code (class, properties and jar files)
  2. Unzip the file your downloaded into a directory by itself and then
  3. copy all the .class and .propteries files and the aniscode.jar file into the directory where you will be serving your animations to the outside world
  4. if you want to use the default enhancement file, download this enh.tab file and copy it into the target directory as well; otherwise, if you have made your own, then just copy it over.
  5. Make your HTML following the examples
  6. Make your JPEG or GIF files (Important Note: do not use the GIF "transparency" option in making your image files or your loops will "flash")
  7. Put the image files into the directory along with the HTML
  8. Turn your users and fans loose!

Note: If you are just updating an existing installation, you need only get this ZIP file (class, properties and jar files only) and unzip it over your current installation of .class and/or .jar file.

Note: Instead of dealing with the .class and properties files, you may instead just copy the aniscode.jar file. If you do this, the applet will load faster on the end user's machine, but you will also have to add an attribute to the <applet> tag:

<applet archive="aniscode.jar" code="AniS.class" height=....>


The AniS Application

If you need to point your users at different hosts for some of your images, you can use the AniS Application. It's a wrapper around the AniS applet that allows your HTML to specify image_base that points away from your host. The downside is that your users will have to install the Java Runtime Environment (JRE). This new capability, introduced in July, 2005, is available by downloading the anisapp.jar file. You need to then run a command-line command:
java -jar anisapp.jar
(you may optionally append the URL of your HTML that invokes the AniS applet). We will consider packaging this with the JRE in the future, to make it easier to use.

You may also run this as a Web Start application by simply clicking here (if you have installed Web Start). You can try this URL if you like:
http://www.ssec.wisc.edu/anis/kmkx.radar
which reads radar image files from another site...
