Scroll Image Installation

Scroll is purely Java based. It is designed to work in all major browsers, with any GIF or JPEG image.


It is very easy to install, works just like any other Java applet, no special server software is needed. Just copy the applets .class and .jar files into the web server, these files are located in the Scroll.zip file. To display an image using Scroll, use the following applet parameters in the HTML code:

Applet parameters

Name: picture - name of gif or jpeg image to use
Value: Name of image, path is relative to the html document.
Example: <param name="picture" value="images/schipp.jpg">

Name: minscrollspeed - minimum scrollspeed when scrolling using the mouse.
Value: Minimum number of pixels to scroll each time the images position is updated
Example: <param name="minscrollspeed" value="1">

Name: maxscrollspeed - minimum scrollscpeed when scrolling using the mouse.
Value: Maximum number of pixels to scroll each time the images position is updated
Example: <param name="minscrollspeed" value="5">

Name: acceleration - how fast should the image accelerate when a cursor key is held down.
Value: A value of 0.1 means the speed will change with 0.1 pixels when the image is updated
Example: <param name="acceleration" value="0.1">

Name: domain - restrict Scroll to run on one domain
Value: name of domain Scroll is running on
Example: <param name="domain" value="www.artistscope.com">

Name: key - your license key
Value: Key obtained by buying an appropriate license
Example: <param name="key" value="xzxowpnzs">

Example HTML code

If you have a domain license for the domain home.site.com, and want to show the image pretty.jpg (200x225 pixels), you simply have to insert the code into your web page where you want it to appear. You can locate the applet code in another directory than the HTML code itself, this might be more tidy. To call the applet, you can then simply specify it's URL to the applet's directory using the codebase parameter like this:

<applet codebase="http://www.yourdomain.com/applets/" archive=Scroll.jar code=Scroll.class name=Scroll width=200 height=225>

Uploading

Always upload Java files as Binary (never use ASCII). The images must be located relative to the URL given by the codebase.
