SpotLight

Mouse over this darkened image to reveal parts of the true picture.


Downloading

The applet may be downloaded for free by clicking on the TAR-file link below (read the FAQ if you're not sure what to do with a TAR file). The FAQ also has step by step instructions on how to embed an applet into your own webpage.

SpotLight2.tar

Once unTARed, you should find the following classes (plus a '.jar' file if you want to use the archive= attribute in the <applet> tag):

Parameters

Below are descriptions of all the parameters you may use to customize the applets to your webpages. Be sure to enclose any parameters that contain white space in double-quotation marks. Most parameters have default values in case you do not specify your own values, but the first two parameters (AUTHOR and COPYRIGHT) are necessary. If you are not sure how to incorporate an applet into a webpage (with its parameter names and values), looks at the source of this webpage and the applet embedded for an example, or read the FAQ page.

  • AUTHOR: This parameter must appear exactly as follows: 
    <param name=AUTHOR value="Eric Harshbarger, http://www.ericharshbarger.org">

  • COPYRIGHT: This parameter must appear exactly as follows: 
    <param name=COPYRIGHT value="SpotLight applet, Copyright 1998, Eric Harshbarger">

  • BACKGROUND: This parameter points to an image file that is used as a background to the applet. All the various texts of the applet will be painted on top of this image. Consult the FAQ page if you are unsure about what image formats you may use.

  • RADIUS: This is the pixel radius of the spotlighted area. The bigger this radius, the more CPU-intensive the applet will be.

  • FADE.RADIUS: This is indicates the 'softness' of the edge of the spotlighted area. If equals to '0', the spotlight is fully lit until the RADIUS is exceeded, at which point the image is completely dark (by DARK.FACTOR). A value greater than 0 indicates the number of pixels over which a soft 'feathering' effect will transition btween the spotlighted area and the surronding darkness.

  • DARK.FACTOR: This should be a decimal between 0.0 and 1.0 (inclusive) that indicates how dark the unlight parts of the image will be. '0.0' indicates complete blackness, while '1.0' indicates the normal brightness of the original image.
