¿Podría alguien decirme cómo es la estructura de un archivo de fuentes True
Type o dónde podría encontrar información sobre ésto?
Muchas gracias.

Frequently Asked Questions
Q.
Is TrueType Open a new font format?
A.
No. TrueType Open fonts are TrueType fonts with extensions. TrueType Open
introduces new table structures that contain additional typographical data.
Q.
To ensure compatibility, do I need to revise all my fonts to be TrueType
Open fonts?
A.
No. TrueType fonts that do not contain TrueType Open information are still
valid fonts. A client can determine which, if any, TrueType Open features a
font contains and make decisions accordingly.
Q.
Can I use TrueType Open fonts on Windows 3.1x?
A.
Yes. Because the basic TrueType font format has not changed, TrueType Open
fonts can be used by operating systems and applications that support
TrueType but do not implement TrueType Open functionality.
Q.
Which TrueType Open features are supported by Windows 95?
A.
A text-processing client can access all TrueType Open tables by using the
GetFontData API and requesting a TrueType Open table by name. The client is
responsible for placing text appropriately according to the information
retrieved.
Q.
Is Microsoft developing tools for creating TrueType Open fonts?
A.
Microsoft is working with Independent Software Vendors (ISVs) to enhance
their font development tools to handle TrueType Open information.
Internally, Microsoft uses a proprietary tool for assembling TrueType Open
binary tables from TrueType Open data in text format.
Q.
What is the difference between Apple's TrueType GX and Microsoft's TrueType
Open?
A.
TrueType Open and TrueType GX address some of the same issues, especially
those arising from one-to-one relationships between characters and glyphs.
However, TrueType Open has a richer two-dimensional positioning model than
TrueType GX. TrueType Open also contains explicit script and language
support, so a text-processing application can adjust its behavior
accordingly.
Another major difference between the two font formats is that TrueType GX
fonts contain state machines, which choose and position glyphs. This format
requires that clients follow a particular model of text processing, and
TrueType GX fonts are difficult for a client to decode. In comparison,
TrueType Open fonts are simple to read and support clients in making their
own decisions regarding text processing.

TrueType Open is an extension to the TrueType font standard. TrueType Open
fonts contain additional information that extends the capabilities of the
fonts to support high-quality international typography:
TrueType Open can associate a single character with multiple glyphs,
and-conversely-it can associate combinations of characters with a single
glyph.
TrueType Open includes two-dimensional information to support features for
complex positioning and glyph attachment.
TrueType Open contains explicit script and language information, so a
text-processing application can adjust its behavior accordingly.
TrueType Open has an open format that allows font developers to define their
own typographical features.
This overview introduces the power and flexibility of the TrueType Open font
model. The rest of the document describes the TrueType Open components in
technical detail that will be useful to font vendors and software developers
creating TrueType fonts and the text-processing applications that use them.
