I have a font with some optical sizes which I want to use. I tried two solutions (below), without success. How can I use optical sizes of a local font? The solutions I tried:

  1. Using \definefontfamily, which gave me correct basic alternatives (italics, bold etc.) and correctly converted --- to em-dashes, but doesn't support changing font according to size (as I understood from the docs).

  2. Using typescripts, which didn't give me correct alternatives (more below) nor converted --- to em-dashes. I was not capable to understand how to configure optical sizes this way (although it seems to be the recommended way).

With typescripts, regular italics were converted to semibold italics. I put semibold declarations on typescript, but not in regular italics. My typescript declaration and usage:

\definebodyfontenvironment[default][em=italic]
\definebodyfontenvironment[12pt][interlinespace=4.2ex]
\definebodyfontenvironment[10pt][interlinespace=3.2ex]

\starttypescript [serif] [garamond]
  \setups [font:fallback:serif]
  \definefontsynonym [Garamond-Regular]         [name:Garamond Premier Pro Regular]
  \definefontsynonym [Garamond-Italic]          [name:Garamond Premier Pro Italic]

  • You have to use Goodies. Dec 20, 2018 at 8:45
  • I recommend that you use file: lookup rather than name:. The name: lookup is much slower and may fail if fonts don't declare their name correctly or there are two fonts which have the same name. Dec 21, 2018 at 5:38

You have to use font Goodies to use design sizes. Font Goodies are Lua scripts which return a table with extra information about the font and are loaded at runtime. More about Goodies can be found in chapter 5.4 “Goodies” in Fonts out of ConTeXt (PDF).

You probably want to use a sans-serif, mono, and math font other than DejaVu. I just added them here for completeness. You should not leave any of these out because if you attempt to use them and they are not defined, strange things happen.

Font alternative can only have two letters, because ConTeXt will use anything after it as the size specifier, as the b in \tfb.

Then you can use this in your document via

\loadtypescriptfile[garamond-premier]

As you can see, this does not look really continuous. This is because I have guessed the values at which the different design sizes should be used. In production, one should carefully fine tune these to achieve a more continuous behaviour.

The output of pdffonts confirms that all fonts are embedded.

System-wide installation

For a system-wide installation you can put the files into appropriate locations in the ConTeXt tree. I just use the local tree within the ConTeXt installation. I show all the commands together with the output they produce on my machine. These might of course differ from yours.

First we get the path of the local tree and then we go there.

$ mtxrun --resolve-path '$TEXMFLOCAL'
/opt/context/tex/texmf-local
$ cd /opt/context/tex/texmf-local

Now we make a directory for the typescript files.

$ mkdir -p tex/context/fonts/mkiv/

In this new directory, create the two files garamond-premier.lfg and type-imp-garamond-premier.mkiv with the contents from above.

Now we make a directory for the OpenType font files. I follow the convention of the directory name scheme <foundry>/<fontname>.

$ mkdir -p fonts/opentype/adobe/garamond-premier/

Place all the OpenType files in there.

Because we have added new files to the tree, we have to rebuild the filename database. This is done using

$ mtxrun --generate

This will take a moment and print a lot of messages to the terminal. Afterwards, you can check whether the new files are detected in the tree

$ mtxrun --find-file garamond-premier.lfg
/opt/context/tex/texmf-local/tex/context/fonts/mkiv/garamond-premier.lfg
$ mtxrun --find-file type-imp-garamond-premier.mkiv
/opt/context/tex/texmf-local/tex/context/fonts/mkiv/type-imp-garamond-premier.mkiv
$ mtxrun --find-file GaramondPremrPro.otf
/opt/context/tex/texmf-local/fonts/opentype/adobe/garamond-premier/GaramondPremrPro.otf

If that all works, you are ready to typeset your document. The typescript should automatically found by \setupbodyfont[garamond-premier] (no \usetypescriptfile or similar necessary).

  • Wow, thank you!!! I didn't know that specific doc, "Fonts out of ConTeXt"! Thank you, this should be sufficient (semibold and medium alternatives, I guess, can be managed the same way, creating custom alternatives). Dec 20, 2018 at 16:21

    @JosédeMattosNeto You might be interested in The definitive guide to ConTeXt MkIV documentation. Dec 20, 2018 at 19:45
  • +1 Exactly what the second half of ConTeXt: Define fonts with additional non-standard styles, alternatives and sizes was asking, without using the terminology. My second MWE tried to automatically switch between the text and display optical sizes of the Libertinus font using \definebodyfont... which for several reasons didn't work.

  • @HenriMenke in the goodies file, it seems that one should declare all sizes used, not ranges as you suggested. I tested your code and opened the PDF in Acrobat to see size vs. font used, and without declaring sizes explicitly it doesn't use my ranges, but seems to use default ranges (caption < 8, regular < 12, subhead < 16, display above). BTW, all-sizes-declared is the way built-in goodies work (for instance lm.lfg). Dec 21, 2018 at 4:59
