This sets the default font-family on <math> elements so that we try to use OpenType MATH fonts that are likely to be installed or fallback to WOFF and obsolete mathematical fonts. Bug: 65532 Change-Id: Id4517a3ce5eab4acdf2264712ba132b972120042

############ A BRIEF DESCRIPTION OF THE FONT ############
|
|
###########################################################################
|
|
|
|
Latin Modern Math is a math companion for the Latin Modern family
|
|
of fonts (see http://www.gust.org.pl/projects/e-foundry/latin-modern) in
|
|
the OpenType format.
|
|
|
|
The math OTF fonts should contain a special table, MATH, described in the
|
|
confidential Microsoft document "The MATH table and OpenType Features
|
|
for Math Processing". Moreover, they should contain a broad collection
|
|
of special characters (see "Draft Unicode Technical Report #25.
|
|
UNICODE SUPPORT FOR MATHEMATICS" by Barbara Beeton, Asmus Freytag,
|
|
and Murray Sargent III). In particular, math OTF fonts are expected
|
|
to contain the following scripts: a basic serif script (regular, bold,
|
|
italic and bold italic), a calligraphic script (regular and bold),
|
|
a double-struck script, a fraktur script (regular and bold), a sans-serif
|
|
script (regular, bold, oblique and bold oblique), and a monospaced script.
|
|
|
|
The basic script is, obviously, Latin Modern. Some scripts, however,
|
|
are borrowed from other fonts (the current selection, however, may
|
|
be subject to change), belonging, however, to the "TeX circle":
|
|
|
|
* the calligraphic and fraktur alphabets are excerpted from the renowned
|
|
Euler family (http://en.wikipedia.org/wiki/AMS_Euler);
|
|
|
|
* the double struck script is excerpted from Alan Jeffrey's bbold font
|
|
(http://www.tug.org/texlive/Contents/live/texmf-dist/doc/latex/bbold/bbold.pdf)
|
|
|
|
* the sans serif and monospaced alphabets are excerpted from
|
|
the Latin Modern Sans and Latin Modern Mono fonts
|
|
(http://www.gust.org.pl/projects/e-foundry/latin-modern);
|
|
sans serif bold Greek symbols (required by the already mentioned
|
|
"Unicode Technical Report #25") were prepared using D.E. Knuth's
|
|
font sources with some manual tuning
|
|
|
|
The main math component, that is, the math extension, was programmed
|
|
from scratch, with an attempt to retain the visual compatiblility
|
|
with the original D.E. Knuth's fonts. In particular, all symbols
|
|
(with a few exceptions) appearing in the D.E. Knuth's "canonical" fonts
|
|
have the same width (rounded) as the corresponding Knuthian ones.
|
|
|
|
Note that the members of all the mentioned alphabets, except
|
|
the main roman alphabet, should be considerd symbols, not letters;
|
|
symbols are not expected to occur in a text stream; instead,
|
|
they are expected to appear lonely, perhaps with some embellishments
|
|
like subscripts, superscripts, primes, dots above and below, etc.
|
|
|
|
To produce the font, MetaType1 and the FontForge library were used:
|
|
the Type1 PostScript font containing all relevant characters was
|
|
generated with the MetaType1 engine, and the result was converted
|
|
into the OTF format with all the necessary data structures by
|
|
a Python script employing the FontForge library.
|
|
|
|
The TeX Gyre Math Project was launched and is supported by
|
|
TeX USERS GROUPS (CS TUG, DANTE eV, GUST, NTG, TUG India, TUG, UK TUG).
