3.2 Fonts
=========
Font files are stored in separate directories, segregated by file type,
and then (in most cases) font supplier and typeface. PK and GF files
need additional structure, as detailed in the next section.
texmf/fonts/TYPE/SUPPLIER/TYPEFACE/
texmf/fonts/enc,lig,map/SUBPATH/
* `TYPE' is the type of font file. The TDS reserves the following
`TYPE' names for common TeX file types:
* `afm', for Adobe font metrics, and `inf' files.
* `gf', for generic font bitmap files.
* `opentype', for OpenType fonts.
* `pk', for packed bitmap files.
* `source', for font sources (Metafont files, property lists,
etc.).
* `tfm', for TeX font metric files.
* `truetype', for TrueType fonts.
* `type1', for PostScript Type 1 fonts (in `pfa', `pfb',
or any other format), and `pfm' files.
* `type3', for PostScript Type 3 fonts.
* `vf', for virtual fonts.
The TDS also reserves the names `enc', `lig', and `map' for font
encoding, ligature, and mapping files, respectively. All of these
directories are structured the same way, with `SYNTAX'
subdirectories, and then `PACKAGE' subsubdirectories. Each of
these file types is intended to be searched along its own
recursively-searched path. The names of the actual files must be
unique within their subtree, as usual. Examples:
fonts/map/dvipdfm/updmap/dvipdfm.map
fonts/map/dvips/lm/lm.map
fonts/enc/dvips/base/8r.enc
The Fontname and Dvips packages have more examples of the `enc' and
`map' types. The `afm2pl' program uses `lig' files.
`pfm' files are included in the `type1' directory, instead of
being given their own directory, for two reasons: 1) a `.pfm' file
is always an adjunct to a given `.pfb' file; 2) they must be
installed from the same directory for Windows programs other than
TeX to use them.
`inf' files are included in the `afm' directory, since an `inf'
and `afm' file can be used to generate a `pfm'. (Unfortunately,
Adobe Type Manager and perhaps other software requires that the
`pfb' be in the same directory as `afm' and `inf' for
installation.)
As usual, a site may omit any of these directories that are
unnecessary. `gf' is a particularly likely candidate for omission.
* `SUPPLIER' is a name identifying font source (examples: `adobe',
`ams', `public'). The TDS reserves the following `SUPPLIER' names:
* `ams', for the American Mathematical Society's AMS-fonts
collection.
* `local', for local additions. See Section ⇒Local
additions.
* `public', for freely redistributable fonts where the supplier
neither (1) requested their own directory (e.g., `ams'), nor
(2) also made proprietary fonts (e.g., `adobe'). It does not
contain all extant freely distributable fonts, nor are all
files therein necessarily strictly public domain.
* `tmp', for dynamically-generated fonts, as is traditional on
some systems. It may be omitted if unnecessary, as usual.
* `TYPEFACE' is the name of a typeface family (examples: `cm',
`euler', `times'). The TDS reserves the following `TYPEFACE' names:
* `cm' (within `public'), for the 75 fonts defined in
`Computers and Typesetting, Volume E'.
* `latex' (within `public'), for those fonts distributed with
LaTeX in the base distribution.
* `local', for local additions. See Section ⇒Local
additions.
Some concrete examples:
texmf/fonts/source/public/pandora/pnr10.mf
texmf/fonts/tfm/public/cm/cmr10.tfm
texmf/fonts/type1/adobe/utopia/putr.pfa

for TeX fonts' (see Appendix ⇒Related references).
