You may want to know how to actually run TTIComp.
Make sure you are in the
right directory. Then type
tticomp -o <tti file name>.
The following options may be used.
-oproduces optimised code. Because optimisation in the case of TrueType instructions means mostly gathering stack pushes and reducing unnecessary zone pointer setting, the resulting code actually is a lot easier to follow in a program such as TrueTypeViewer. I recommend you use this switch unless you have good reasons not to. Oh, by the way, the switch will reduce the size of the instructions with a factor of 5 or so.
-lproduces a program listing. This may be useful to see where the compiler didn't understand you or where you didn't get the compiler. It will also print the list of predefined functions, which may be useful as well.
