====== Comment utiliser les polices “Concrete?” ======


Les polices [[wp>Concrete_Roman|Concrete Roman]] ont été conçues par Donald Knuth
pour un livre intitulé //[[isbn>978-0201558029|Concrete Mathematics]]//,
qu'il a écrit avec Ronald Graham et Oren Patashnik (ce dernier étant aussi connu pour [[https://www.latex-fr.net/1_generalites/glossaire/qu_est_ce_que_bibtex_et_biblatex|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 [[https://www.latex-fr.net/1_generalites/glossaire/qu_est_ce_que_plain_tex|Plain TeX]], bien sûr,
avec des macros supplémentaires qui peuvent être trouvées dans le fichier ''[[ctanpkg>gkpmac|gkpmac.tex]]''.


The packages [[ctanpkg>beton]], [[ctanpkg>concmath]], and [[ctanpkg>ccfonts]]
are LaTeX packages that change the default text fonts from Computer Modern to Concrete.
Packages [[ctanpkg>beton]] and [[ctanpkg>ccfonts|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 [[ctanpkg>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
[[ctanpkg>amsmath]]).  The independently-developed [[ctanpkg>eulervm]]
bundle is therefore preferred to the [[ctanpkg>euler]] package.  (Note
that installing the [[ctanpkg>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
[[ctanpkg>eulervm]] distribution.)

A few years after Knuth's original design, Ulrik Vieth
designed the Concrete Math fonts.  Packages
[[ctanpkg>concmath]], and [[ctanpkg>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 [[ctanpkg>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 [[ctanpkg>concmath]] or
[[ctanpkg>ccfonts]] and you want to follow this suggestion, then use the
package with ''boldsans'' class option (in spite of the fact
that the [[ctanpkg>concmath]] documentation calls it ''sansbold'' class option).
If you are using [[ctanpkg>beton]], add
<code latex>
\renewcommand{\bfdefault}{sbc}
</code>
to the preamble of your document.

Type 1 versions of the fonts are available.  For OT1 encoding,
they are available from [[https://www.latex-fr.net/5_fichiers/fontes/fontes_t1_pour_les_mathematiques|MicroPress]].  The
[[https://www.latex-fr.net/5_fichiers/fontes/tracer_les_contours_d_une_police_metafont|CM-Super fonts]] contain Type 1 versions
of the Concrete fonts in T1 encoding.
