At the heart of Desktop Pizazz are its modules. Each module is a separate product that uses the Desktop Pizazz interface to access its functionality. Each module contains specific images and behavior that make each one unique, and typically represent a particular theme or concept. An example of a module could be an aquarium, where fish swim about and bubbles rise to the surface. Through the interface, you could modify settings for the aquarium, such as the number of fish, how often the bubbles appear, and perhaps the schedule for feeding the fish.
Since people view their desktops under different resolutions, or screen dimensions, Desktop Pizazz modules provide their graphics in some of the most common resolutions. Resolutions are referenced by their width and height. The typical resolutions are 640x480, 800x600, and 1024x768. If you use a resolution larger than the largest one provided by the module, the image will contain a border which extends to the full size of your desktop. You also have the option of "stretching" the module image to fit your desktop. Desktop Pizazz always attempts to load the largest graphics resolution that will fit on your current desktop.
In addition to screen resolutions described above, people also view their desktops under different bit-depths, or numbers of colors. Desktop Pizazz modules provide their graphics in both 8-bit (256) color and 24-bit (16 million) color. If your desktop display is only set to 8-bit color, you cannot view the 24-bit graphics. However, if your display supports greater than 8-bit color, you can view either the 8-bit or 24-bit graphics. Desktop Pizazz always attempts to load the graphics with the highest number of colors that are supported by your current desktop.
