Comment dessiner avec TeX?
Il existe de nombreux logiciels permettant de faire des dessins directement
dans (La)TeX (plutôt que d'importer des graphiques créés avec un autre outil),
allant de la simple utilisation de l'environnement
picture de LaTeX,
avec ses versions améliorées comme
eepic, au dessin sophistiqué (mais lent)
avec PicTeX. En fonction de votre type de dessin et de votre configuration,
voici quelques systèmes à envisager :
picture environment provides rather primitive
drawing capabilities (anything requiring more than linear
calculations is excluded, unless a font can come to your help). The
environment's tedious insistence on its own
\unitlength, as the
basic measurement in a diagram, may be avoided by use of the
picture package, which detects whether a length is quoted
as a number or as a length, and acts accordingly.
epic was designed to make use of the LaTeX
picture environment somewhat less agonising;
eepic extends it, and is capable of using
\special commands to improve printing performance. (If the
\specials aren't available, the eepicemu will do the
business, far less efficiently.
pict2e; this was advertised in
the LaTeX manual, but didn't appear for nearly
ten years after publication of the book! It removes all the petty
restrictions that surround the use of the
environment. It therefore suffers only from the rather
eccentric drawing language of the environment, and is a far more
useful tool than the original environment has ever been. (Note that
pict2e supersedes David Carlisle's stop-gap
PicTeX is a venerable, and very powerful, system, that draws by placing dots on the page to give the effect of a line or curve. While this has the potential of great power, it is (of course) much slower than any of the other established packages. What's more, there are problems with its documentation.
PSTricks gives you access to the (considerable) power of
PostScript via a set of TeX macros, which talk to PostScript using
''\special'' commands. Since PostScript is itself a
pretty powerful programming language, many astounding things can in
principle be achieved using PSTricks (a wide range of
contributed packages, ranging from world mapping to lens design
diagrams, is available).
by default specific to
dvips, but there is
a PSTricks “driver” that allow Pstricks to
operate under XeTeX. pdfTeX users may use pst-pdf,
which (like epstopdf — see
pdfLaTeX graphics) generates
PDF files using an auxiliary program, from PSTricks
commands (pst-pdf also requires a recent installation of
the preview package).
TikZ: while PStricks is very powerful and convenient from “traditional” TeX, using it with pdfLaTeX is pretty tiresome: if you simply want the graphical capabilities, PGF, together with its “user-oriented” interface TikZ, may be a good bet for you. While PDF has (in essence) the same graphical capabilities as PostScript, it isn't programmable; PGF provides LaTeX commands that will utilise the graphical capabilities of both PostScript and PDF equally. Pgf has extensive mathematical support, which allows it to rival PSTricks' use of the computation engine within PostScript. The TikZ manual is enormous, but a simple introduction which allows the user to get a feel for the capabilities of the system, is available at http://cremeronline.com/LaTeX/minimaltikz.pdf.
MetaPost; you liked MetaFont, but never got to grips with font files? Try MetaPost — all the power of MetaFont, but it generates PostScript figures; MetaPost is nowadays part of most serious (La)TeX distributions. Knuth uses it for all his work…
Note that you can "embed" MetaPost source in your document (i.e., keep it in-line with your LaTeX code).
You liked MetaFont (or MetaPost), but find the language difficult?
Mfpic makes up MetaFont or MetaPost code for you using
familiar-looking (La)TeX macros. Not quite the full power
of MetaFont or MetaPost, but a friendlier interface, and with MetaPost output
the results can be used equally well in either LaTeX or pdfLaTeX.
You liked PicTeX but don't have enough memory or time? Look at the late Eitan Gurari's dratex: it is just as powerful, but is an entirely new implementation which is not as hard on memory, is much more readable, as well as in the author's book “TeX and LaTeX: Drawing and Literate Programming”, which remains available from on-line booksellers.
In addition, there are several means of generating code for your
graphics application (
MetaPost, at least) in-line in your document, and then have them
processed in a command spawned from your (La)TeX run. For details,
