description: A small howto for importing OTF fonts

|
In the last days I had an interesting Problem to solve, which involved
|
||
|
|
LaTeX, OTF font files and a special set of requirements. I needed to import and
|
||
|
|
use the OTF fonts in a LaTeX document and this document needed to be compiled
|
||
|
|
through pdflatex.
|
||
|
|
|
||
|
|
First off: If you need to use OTF fonts in LaTeX documents, you can simply
|
||
|
|
switch to XeLaTeX or LuaLaTeX, like I did in the first place. Both of these
|
||
|
|
environments support the package `fontspec`, which makes using fonts installed
|
||
|
|
in your system extremely easy. So if you can, switch the environment.
|
||
|
|
|
||
|
|
If you can't switch the environment, don't want to, feel a little adventurous or
|
||
|
|
even want to feel some of the innards of LaTeX you can choose the path I am
|
||
|
|
about to show.
|
||
|
|
|
||
|
|
Before you can start, you need to install the [LCDF typetools][lcdf], which is
|
||
|
|
a set of tools for manipulating the font definitions of LaTeX. Most GNU/Linux
|
||
|
|
distributions have them in their repositories, Mac users can install them
|
||
|
|
through homebrew and even Windows binaries are available on the website.
|
||
|
|
Additionally make sure, that you use `updmap` in system mode and have root
|
||
|
|
privileges.
|
||
|
|
|
||
|
|
To create the font mappings from the OTF, you simply run
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo otftotfm -a <fontfile> --vendor <vendor> --typeface <typeface> -e texnansx
|
||
|
|
```
|
||
|
|
Where you replace the items in the angle brackets. This not only produces the
|
||
|
|
mappings, but also places them in the right directory. (If `otftotfm` complains
|
||
|
|
because of `updmap`, run the `updmap` commands in the error messages as
|
||
|
|
`updmap-sys`.)
|
||
|
|
|
||
|
|
Before you can actually use the Font, you have to write your own font
|
||
|
|
definition. A small template for this follows, which should be saved as
|
||
|
|
`T1<typeface>.df`
|
||
|
|
```latex
|
||
|
|
\ProvidesFile{T1<fontname>.fd}
|
||
|
|
[YYYY/mm/dd foobar]
|
||
|
|
\DeclareFontFamily{T1}{<fontname>}{}
|
||
|
|
\DeclareFontShape{T1}{<fontname>}{m}{n} {<-> <fontface> } {}
|
||
|
|
\endinput
|
||
|
|
```
|
||
|
|
Here you can define `<fontname>` as you wish, the other elements in angle
|
||
|
|
brackets correspond to the box above.
|
||
|
|
|
||
|
|
To actually use it, you can call
|
||
|
|
```latex
|
||
|
|
\renewcommand*{\familydefault}{<fontname>}
|
||
|
|
```
|
||
|
|
from your document to change the font in the whole document, assuming the
|
||
|
|
`T1<fontname>.fd` is in your project folder, or call
|
||
|
|
```latex
|
||
|
|
Lorem ipsum {\fontfamily{<fontname>}\fontseries{m}\fontshape{n}
|
||
|
|
\selectfont dolor sit} amet
|
||
|
|
```
|
||
|
|
to change the font only for "dolor sit" in this example.
|
||
|
|
|
||
|
|
There are tons of other options how to handle fonts in LaTeX, but this is the
|
||
|
|
most convenient one I found.
