Fonts E Installation and Use of Opentype Fonts in L a T E X

ˆe emerging file standard in digital typography is the OpenType font standard, jointly developed by Microso and Adobe. OpenType fonts are natively supported by several popular operating systems and have many features and advantages that make them desirable for highquality typography. However, OpenType fonts are not natively supported by the standard TEX engine. ˆis article is a practical guide to installing OpenType fonts for use as text fonts in LATEX. ˆe steps to install anOpenType font for use in LATEX are: . For each OpenType font file, and for each combination of attributes for that font file, generate and install font metric and encoding files. . Next, for each font family, generate and install a font description (.fd) file that maps LATEX font selection commands to the installed font files. . Finally, write and install a style (.sty) file that allows the user to select the font and its options for use within TEX. We begin by discussing font background, the TEX font handling scheme, and existing font tools, then describe each of the three steps above in detail.  Font basics and font families ˆe advanced typographic features of the OpenType font format have motivated its widespread use in a variety of demanding applications. Before we dive into supporting OpenType in TEX, however, let’s take a step back and look at our eventual goal. As a TEX user, we are less interested in using just a single font with a single set of options and more interested in using a font family: a collection of compatible font variants, usually from the same typeface, that can be used together. For instance, we might want to group together a plain and an italic form of a particular typeface into a family. Wemight want to make small caps available in our family as well, or perhaps incorporate several different weights or optical sizes. Once we have defined our font family, we would then like to ask TEX to enable the entire family with a single command. As an example, this document is typeset in an Adobe OpenType Minion Pro font family with old-style figures, with code Editor’s note: Due to the nature of this article, it is typeset in the Adobe Minion and Adobe Myriad typefaces. We thank Adobe for permission to use these fonts in both the print and web publications.
