/*
Sample project for generating JViewPro report script without using JViewPro

How to generate:
A class, Script has been provided below.

-To set a JViewPro property (or some relevant methods, such as storePage()),
use the class's addLine method;

-To add a text or graphics object, use the class's addObject method that
has the same arguments as the corresponding JViewPro's; and

-To save the script, use the saveScript method.

How to view and print:
The generated script can be loaded, viewed and printed using
JViewPro JavaBean embedded in your applets or applications. The
related JViewPro methods are loadScrip, loadScriptURL, preview and
printPages.
For test purpose, you can also view and print the script
using the Mini Viewer supplied with the trial copy (the
program is in the Viewer sub-directory under the demo directory).
