This module is a bit more split up that I'd like but since we also want to test -with plain it has to be so. This module is part of -and discussion about improvements and functionality mostly happens on the - mailing list.

- -

The specification of OpenType is (or at least decades ago was) kind of vague. -Apart from a lack of a proper free specifications there's also the problem that -Microsoft and Adobe may have their own interpretation of how and in what order to -apply features. In general the Microsoft website has more detailed specifications -and is a better reference. There is also some information in the FontForge help -files. In the end we rely most on the Microsoft specification.

- -

Because there is so much possible, fonts might contain bugs and/or be made to -work with certain rederers. These may evolve over time which may have the side -effect that suddenly fonts behave differently. We don't want to catch all font -issues.

- -

After a lot of experiments (mostly by Taco, me and Idris) the first implementation -was already quite useful. When it did most of what we wanted, a more optimized version -evolved. Of course all errors are mine and of course the code can be improved. There -are quite some optimizations going on here and processing speed is currently quite -acceptable and has been improved over time. Many complex scripts are not yet supported -yet, but I will look into them as soon as users ask for it.

- -

The specification leaves room for interpretation. In case of doubt the Microsoft -implementation is the reference as it is the most complete one. As they deal with -lots of scripts and fonts, Kai and Ivo did a lot of testing of the generic code and -their suggestions help improve the code. I'm aware that not all border cases can be -taken care of, unless we accept excessive runtime, and even then the interference -with other mechanisms (like hyphenation) are not trivial.

- -

Especially discretionary handling has been improved much by Kai Eigner who uses complex -(latin) fonts. The current implementation is a compromis between his patches and my code -and in the meantime performance is quite ok. We cannot check all border cases without -compromising speed but so far we're okay. Given good test cases we can probably improve -it here and there. Especially chain lookups are non trivial with discretionaries but -things got much better over time thanks to Kai.

- -

Glyphs are indexed not by unicode but in their own way. This is because there is no -relationship with unicode at all, apart from the fact that a font might cover certain -ranges of characters. One character can have multiple shapes. However, at the - end we use unicode so and all extra glyphs are mapped into a private -space. This is needed because we need to access them and has to include -then in the output eventually.

- -

The initial data table is rather close to the open type specification and also not -that different from the one produced by but we uses hashes instead. -In that table is packed (similar tables are shared) and cached on disk -so that successive runs can use the optimized table (after loading the table is -unpacked).

- -

This module is sparsely documented because it is has been a moving target. The -table format of the reader changed a bit over time and we experiment a lot with -different methods for supporting features. By now the structures are quite stable

- -

Incrementing the version number will force a re-cache. We jump the number by one -when there's a fix in the reader or processing code that can result in different -results.

- -

This code is also used outside context but in context it has to work with other -mechanisms. Both put some constraints on the code here.
