Authors: David Barnes and Michael Kölling
This project is part of the material for the book
Objects First with Java - A Practical Introduction using BlueJ
Sixth edition
David J. Barnes and Michael Kölling
Pearson Education, 2016
It is discussed in chapter 13.
To use this project, create an instance of class ImageViewer.
This version refactors some of the code to improve its structure.
