Learn how to use the Guzdial-Ericson Multimedia Class Library

Revised: Sat Apr 02 09:43:04 CDT 2016

This page is included in the following Books:

Table of contents


I have published a large number of modules that use a multimedia class library developed and made available by Mark Guzdial and Barbara Ericson of the Georgia Institute of Technology. The purpose of this module is to provide the information that you will need to obtain and use acopy of that library.

If you find that you don't understand the material in this module, you probably need to review the material in the following modules:

In addition, you may find it useful to search the web for and study a few tutorials on the Windows "command prompt" as well asa few tutorials on Windows batch files. Here are a couple of possibilities that I found with a rudimentary search:

If you are using a different operating system, you will need to find similar tutorials that match up with the operating system that you are using.

Among other things, the Guzdial-Ericson multimedia class library makes it practical to write object-oriented programs for the manipulation of images in aninteresting and educational way. For example, the image in Figure 1 was produced by manipulating and merging the images shown in Figure 2 and Figure 3 .

Figure 1 - Result of merging two images.

This image shows the result of merging an image of a penguin  with an image of a rabbot. The picture morphs from the penguin image on the left to the rabbit image on the right.

One of the input images is shown in Figure 2 .

Figure 2 - Input image #1.

This is the rabbit image that was merged with  the penguin image to produce the resulting image shown in Figure 1.

The other input image is shown in Figure 3 .

Figure 3 - Input image #2.

This is the penguin image that was merged with  the rabbit image to produce the resulting image shown in Figure 1.


The Guzdial-Ericson library was originally published by Guzdial and Ericson in conjunction with their book Introduction to Computing and Programming with Java: A Multimedia Approach . While the book isn't free, the library is freely available and is publishedunder a Creative Commons Attribution 3.0 United States License .

As of July, 2012, the latest version of the library can be downloaded in a zip file named bookClasses-3-9-10-with-doc.zip at (External Link) Additional information is available at (External Link) .

Download the library

In order to work with the programs in the modules that use the library, you will need to download a copy of the latest version of the library from the sitelisted above. To guard against the possibility of that link becoming broken at some point in the future, I am depositing a backup copy of the zipfile containing the library on the cnx.org site and you can download it here .

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
