1. Introduction

Why is there a testpattern generator using the LibGGI API?

Well, for several reasons.

• I wanted a tool to test (quickly) whether a certain resolution works as expected. And often enough it does not.
• I wanted to learn how the LibGGI API works. Sort of succeeded :-).
• There are several tools like this, most notably
  • ctmon for DOS, from the Heise Verlag,
  • Nokia's ntest package, where I 'researched' a lot of ideas
  • Heise's new Java-based test I can't run yet :-(,
  but none for Linux I am aware of.

Why is there this documentation?

I wanted to check out the sgmltools package, and I start to like it. And because it is good to know what a program is supposed to do.
