This module is one of a series of modules designed to teach you about Object-Oriented Programming (OOP) using Java.
The program described in this module requires the use of the Guzdial-Ericson multimedia class library. You will find download, installation, and usageinstructions for the library at Java OOP: The Guzdial-Ericson Multimedia Class Library .
I recommend that you open another copy of this document in a separate browser window and use the following links to easily find and view the Figuresand Listings while you are reading about them.
n this lesson, you will learn how to write a program to do green-screen processing to superimpose a source image onto a destination image while making the green background of the source image appear to betransparent.
Program specifications
Write a program named Prob03 that uses the class definition shown in Listing 1 and Ericson's media library along with the image files in the following list to produce the five graphic output imagesshown in Figure 1 through Figure 5 .
Figure 1 - Input image file Prob03a.bmp.
Figure 2 - Input image file Prob03b.bmp.
Figure 3 - Input image file Prob03c.bmp.
Figure 4 - Input image file Prob03d.jpg.
Figure 5 - Output picture.
New classes
You may define new classes as necessary to cause your program to behave as required, but you may not modify the class definition for the class named Prob03 given in Listing 1 .
Required output text
In addition to the output images mentioned above, your program must display your name and one other line of text on the command-line screen as shown in Figure 6 .

This program receives three views of an ice skater in bmp files with a pure green background along with a jpg file containing a snow scene.
All four files show the Alice runtime panel with the words World Running... and several associated buttons. (See Figure 1 .)
Program behavior
The program performs the following actions:
