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 scripts 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, TeX Gyre Termes. Symbols, namely, +calligraphic, double struck, Greek, sans serif bold Greek, and Hebrew, +were drawn from scratch. The main math component, that is, the math +extension, was also programmed from scratch. + +Some scripts, however, are borrowed from other fonts (the current +selection, however, may be subject to change): + + * The fraktur alphabets (regular and bold) is excerpted + from the Leipziger Fraktur replica by Peter Wiegel + ( http://www.peter-wiegel.de/Leipzig.html ) + with the kind permission of the author. + + * The sans serif alphabets (regular, oblique, bold, and + bold oblique) are excerpted from TeX Gyre Heros + http://www.gust.org.pl/projects/e-foundry/tex-gyre/heros + (actually, the sans serif bold Greek symbols are based + on TeX Gyre Heros Greek alphabet). + + * The monospaced alphabet is excerpted from TeX Gyre Cursor + http://www.gust.org.pl/projects/e-foundry/tex-gyre/cursor + +Note that the members of all the mentioned alphabets, except +the main roman alphabet, should be considered 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. + +Recent changes (ver. 1.502 --> ver. 1.543) comprised +mainly interline settings in OTF tables (HHEA and +OS/2) and the correction of the unicode slots assigned to +contour integrals (glyphs `clockwise contour +integral', u+2232, and `anticlockwise contour +integral', u+2233, used to have swapped slots). + + * * * + +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). +Hearty thanks to the representatives of these groups and also +to all people who helped with their work, comments, ideas, +remarks, bug reports, objections, hints, consolations, etc. |
