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 .

Questions & Answers

can someone help me with some logarithmic and exponential equations.

sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
what is nanomaterials​ and their applications of sensors.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
