ProMap is an imagemap applet designed for use in website navigation. It consists of three .class files (ryProMap.class, ryLightFilter.class and ryMonoFilter.class) and requires at least one image file to be specified in a parameter.

Starting from a basis of this image, sections of the applet can be defined as hotspots (known as 'Areas') by plotting their coordinates. ProMap allows up to 50 Areas to be defined. When the mouse enters a defined Area, it may react in several different ways - by playing a sound, placing a 3D border around the Area, applying a 3D filter to the area, grayscaling the area, displaying an animated or static message in the status-bar or on the image itself, replacing the Area with the same section of an alternative image, or any combination of those options.

If the mouse is clicked inside a defined Area, similar audio and visual feedback is possible. Each Area can link to up to four different URLs with a single click, each with its own frame or window target.

ProMap also has a separate mode, Testmode, for use when setting up the applet. In Testmode, ProMap outlines and numbers all defined Areas on the image, displays the current mouse coordinates, and allows you to draw an Area directly onto the image. As you draw the image, ProMap displays the coordinates you would enter into your HTML code along with the current width and height of the rectangle you're drawing.
