In order to setup a clickable image, you need to define a configuration file which specifies the location of various areas within the image that, when selected, will act as links to other hypertext resources. The configuration file defines the areas of the image (using rectangles, circles, and polygons) that you wish to use as hypertext links.
For example, let's take a look at the configuration file for the square-circle-triangle image:
# square-circle-triangle default http://eelab.usyd.edu.au/~rodica/itopics/map-gray.html rect http://eelab.usyd.edu.au/~rodica/itopics/map-red.html 17,22 91,93 circle http://eelab.usyd.edu.au/~rodica/itopics/map-blu.html 136,53 175,56 poly http://eelab.usyd.edu.au/~rodica/itopics/map-gren.html 183,90 222,18 261,89 183,89
Now let's examine each of these statements, one line at a time.
