Comment utiliser les polices “Concrete?”
Les polices Concrete Roman ont été conçues par Donald Knuth
pour un livre intitulé Concrete Mathematics,
qu'il a écrit avec Ronald Graham et Oren Patashnik (ce dernier étant aussi connu pour BibTeX).
Knuth n'a conçu que des polices de texte, car le livre utilisait les polices Euler
pour les mathématiques. Le livre a été composé
avec Plain TeX, bien sûr,
avec des macros supplémentaires qui peuvent être trouvées dans le fichier gkpmac.tex.
The packages beton, concmath, and ccfonts
are LaTeX packages that change the default text fonts from Computer Modern to Concrete.
Packages beton and ccfonts also slightly increase
the default value of \baselineskip to account for the rather heavier weight of the
Concrete fonts. If you wish to use the Euler fonts for
mathematics, as Knuth did, there's the euler package which
has been developed from Knuth's own Plain TeX-based set: these
macros are currently deprecated (they clash with many things, including
amsmath). The independently-developed eulervm
bundle is therefore preferred to the euler package. (Note
that installing the eulervm bundle involves installing a
series of virtual fonts. While most modern distributions seem to have
the requisite files installed by default, you may find you have to
install them. If so, see the file readme in the
eulervm distribution.)
A few years after Knuth's original design, Ulrik Vieth designed the Concrete Math fonts. Packages concmath, and ccfonts also change the default math fonts from Computer Modern to Concrete and use the Concrete versions of the AMS fonts (this last behaviour is optional in the case of the concmath package).
There are no bold Concrete fonts, but it is generally accepted that
the Computer Modern Sans Serif demibold condensed fonts are an
adequate substitute. If you are using concmath or
ccfonts and you want to follow this suggestion, then use the
package with boldsans class option (in spite of the fact
that the concmath documentation calls it sansbold class option).
If you are using beton, add
\renewcommand{\bfdefault}{sbc}
to the preamble of your document.
Type 1 versions of the fonts are available. For OT1 encoding, they are available from MicroPress. The CM-Super fonts contain Type 1 versions of the Concrete fonts in T1 encoding.
