====== Using the Latin Modern fonts ======


The [[ctanpkg>lm|lm]] fonts are an exciting addition to
the armoury of the (La)TeX user: high quality outlines of fonts that
were until recently difficult to obtain, all in a free and
relatively compact package.  However, the spartan information file
that comes with the fonts remarks "It is presumed that a potential
user knows what to do with all these files".  This answer aims to
fill in the requirements: the job is really not terribly difficult.

Note that teTeX distributions, from version 3.0, already have the
[[ctanpkg>lm|lm]] fonts: all you need do is use them.  The fonts may also
be installed via the package manager, in a current MiKTeX system.
The remainder of this answer, then, is for people who don't use such
systems.

The font (and related) files appear on CTAN as a set of
single-entry [[FAQ-tds|TDS trees]] ---
''fonts'', ''dvips'', ''tex'' and ''doc''.  The ''doc''
subtree really need not be copied (it's really a pair of sample
files), but copy the other three into your existing Local
''$TEXMF'' tree, and
[[FAQ-inst-wlcf|update the filename database]].

Now, incorporate the fonts in the set searched by pdfLaTeX,
''dvips'', ''dvipdfm''/''dvipdfmx'', your
previewers and Type 1-to-PK conversion programs, by

  * On a teTeX system earlier than version 2.0, edit the file ''$TEXMF/dvips/config/updmap'' and insert an absolute path for the ''lm.map'' just after the line that starts ''extra_modules="'' (and before the closing quotes).
  * On a teTeX version 2.0 (or later), execute the command
<code bash>
updmap --enable Map lm.map
</code>
  * On a MiKTeX system earlier than version 2.2, the "Refresh filename database" operation, which you performed after installing files, also updates the system's "PostScript resources database".
  * On a MiKTeX system, version 2.2 or later, update ''updmap.cfg'' as described in the MiKTeX [[http://docs.miktex.org/manual/psfonts.html#chgupdmapcfg|online documentation]].  Then execute the command ''initexmf --mkmaps'', and the job is done.

To use the fonts in a LaTeX document, you should ''\usepackage{lmodern}'' this will make the fonts the default
for all three LaTeX font families ("roman", "sans-serif" and "typewriter").  You also need ''\usepackage[T1]{fontenc}'' for text, and ''\usepackage{textcomp}'' if you want to use any of the TS1-encoding symbols.  There is no support for using fonts according to the OT1 encoding.
