Over time, \XeTeX\ was extended to support OpenType +% fonts and then was ported into a cross-platform program to run also on Windows +% and Linux. +% +% More recently, \LuaTeX\ is fast becoming the \TeX\ engine of the day; it +% supports unicode encodings and OpenType fonts and opens up the internals of +% \TeX\ via the Lua programming language. Hans Hagen's Con\TeX t Mk.\,IV is a +% re-write of his powerful typesetting system, taking full advantage of +% \LuaTeX's features including font support; a kernel of his work in this area +% has been extracted to be useful for other \TeX\ macro systems as well, and +% this has enabled \pkg{fontspec} to be adapted for \LaTeX\ when run with the +% \LuaTeX\ engine. Elie Roux and Khaled Hosny have been instrumental and +% invaluable with this development work. +% +% \section{Introduction} +% +% The \pkg{fontspec} package allows users of either \XeTeX\ or \LuaTeX\ to +% load OpenType fonts in a \LaTeX\ document. No font installation is necessary, +% and font features can be selected and used as desired throughout the document. +% +% Without \pkg{fontspec}, it is necessary to write cumbersome font definition +% files for \LaTeX, since \LaTeX's font selection scheme (known as the +% `\textsc{nfss}') has a lot going on behind the scenes to allow easy +% commands like \cmd\emph\ or \cmd\bfseries. With an uncountable number of +% fonts now available for use, however, it becomes less desirable to have to +% write these font definition (|.fd|) files for every font one wishes to use. +% +% Because \pkg{fontspec} is designed to work in a variety of modes, this +% user documentation is split into separate sections that are designed to be +% relatively independent. Nonetheless, the basic functionality all behaves in +% the same way, so previous users of \pkg{fontspec} under \XeTeX\ should have +% little or no difficulty switching over to \LuaTeX. +% +% This manual can get rather in-depth, as there are a lot of details +% to cover. See the example documents \path{fontspec-xetex.tex} and +% \path{fontspec-luatex.tex} for a complete minimal example with each engine. +% +% \subsection{About this manual} +% +% As of version 2.0 with the addition of \LuaTeX\ support, this manual +% is still in the process of being re-written. +% It currently contains no typeset examples. +% Your patience and feedback is appreciated! +% +% \section{Package loading and options} +% +% For basic use, no package options are required: +% \begin{Verbatim} +% \usepackage{fontspec} +% \end{Verbatim} +% +% In brief, \pkg{fontspec}'s package options are +% \begin{description}[nolistsep,font=\ttfamily] +% \item [no-math] Don't change any maths fonts; +% \item [no-config] Don't load \pkg{fontspec.cfg}; and, +% \item [quiet] Output \pkg{fontspec} warnings in the log file rather than the console output. +% \end{description} +% These are described in more detail below. +% +% \paragraph{\XeTeX\ users only} +% \name{Ross Moore}'s \pkg{xunicode} package is recommended for +% providing backwards compatibility with \LaTeX's methods for accessing extra +% characters and accents (for example, |\%|, |\$|, |\textbullet|, |\"u|, and +% so on), plus many more unicode characters. The \pkg{xltxtra} package adds a +% couple of general improvements to \LaTeX\ under \XeTeX; it also provides the +% \cmd\XeTeX\ macro to typeset the \XeTeX\ logo. +% +% \paragraph{\LuaTeX\ users only} +% In order to load fonts by their name rather than by their filename (\eg, `Latin Modern Roman' instead of `ec-lmr10'), you may need to run the script \texttt{mkluatexfontdb.lua}, which is distributed with the \pkg{luaotfload} package. Please see its documentation for more information. +% Note that the \pkg{xunicode} package is not required as it has been +% incorporated directly into the unicode font definitions (see the \pkg{euenc} package for more information). +% +% \paragraph{\pkg{babel}} +% \emph{The \pkg{babel} package is not really supported!} Especially Vietnamese, +% Greek, and Hebrew at least might not work correctly, as far as I can tell. +% There's a better chance with Cyrillic and Latin-based languages, +% however---\pkg{fontspec} ensures at least that fonts should load correctly, +% but hyphenation and other matters aren't guaranteed. Under \XeTeX, the +% \pkg{polyglossia} package is recommended instead as a modern replacement for +% \pkg{babel}. +% +% +% +% \subsection{Maths fonts adjustments} +% By default, \pkg{fontspec} adjusts \LaTeX's +% default maths setup in order to maintain the correct Computer Modern symbols +% when the roman font changes. However, it will attempt to avoid doing this if +% another maths font package is loaded (such as \pkg{mathpazo} or my upcoming +% \pkg{unicode-math} package). +% +% If you find that it is incorrectly changing the maths font when it should be +% leaving well enough alone, apply the |[no-math]| package option to manually +% suppress its maths font. +% +% \subsection{Configuration} If you wish to customise any part of the +% \pkg{fontspec} interface (see later in this manual, \vref{sec:newfeatures} +% and~\ref{sec:aliasfontfeature}), this should be done by creating your own +% \texttt{fontspec.cfg} file, \note{An example is distributed with the package.} +% which will be automatically loaded if it is found by \XeTeX. Either place it +% in the same folder as the main document for isolated cases, or in a location +% that \XeTeX\ or \LuaTeX\ searches by default; \eg\ in Mac\TeX: \path{~/Library/texmf/tex/latex/}. +% The package option |[no-config]| will suppress this behaviour under all circumstances. +% +% \subsection{Warnings} +% \label{sec:quiet-warnings} +% +% This package can give many warnings that can be harmless if you know what +% you're doing. Use the |[quiet]| package option to write these warnings to the +% transcript (\texttt{.log}) file instead. +% +% Use the |[silent]| package option to completely suppress these warnings if you +% don't even want the |.log| file cluttered up. +% +% +% +% +% +% \clearpage +% \part{General font selection} +% +% This section concerns the variety of commands that can be used to select +% fonts. +% +% \cmdbox{% +% \CMD{~~~~~\string\fontspec} \oarg{font features} \marg{font name}\\ +% \CMD{~~\string\setmainfont} \oarg{font features} \marg{font name}\\ +% \CMD{~~\string\setsansfont} \oarg{font features} \marg{font name}\\ +% \CMD{~~\string\setmonofont} \oarg{font features} \marg{font name}\\ +% \CMD{\string\newfontfamily} \meta{cmd} \oarg{font features} \marg{font name} +% } +% +% These are the main font-selecting commands of this package. +% The \cs{fontspec} command selects a font for one-time use; all +% others should be used to define the standard fonts used in a document. +% They will be described later in this section. +% +% The font features argument accepts comma separated +% \meta{font feature}=\meta{option} lists; these are described in later: +% \begin{itemize} +% \item For general font features, see \vref{sec:font-ind-features} +% \item For OpenType fonts, see Part~\vref{sec:opentype-features} +% \item For \XeTeX-only general font features, see Part~\vref{sec:xetex-features} +% \item For features for \AAT\ fonts in \XeTeX, see Part~\vref{sec:aat-features} +% \end{itemize} +% +% \section{Font selection} +% +% In both \LuaTeX\ and \XeTeX, fonts can be selected either by `font name' or +% by `file name'. +% +% \subsection{By font name} +% +% Fonts known to \LuaTeX\ or \XeTeX\ may be loaded by their names. +% `Known to' in this case generally means `exists in a standard fonts location' +% such as |~/Library/Fonts| on \MacOSX, or |C://WINNT/Fonts| on Windows. +% +% The simplest example might be something like +% \begin{Verbatim} +% \fontspec[ ... ]{Cambria} +% \end{Verbatim} +% in which the bold and italic fonts will be found automatically +% (if they exist) and are immediately accessible with the usual +% \cs{textit} and \cs{textbf} commands. +% +% TODO: add explanation for how to find out what the `font name' is. +% +% +% \subsection{By file name} +% +% When selecting fonts by file name, any font that can be found in the default +% search paths may be used directly (including in the current directory) +% without having to explicitly define the location of the font file on disk. +% +% Note that \XeTeX\ with the |xdvipdfmx| driver and \LuaTeX\ can both select +% fonts in this way, but \XeTeX\ with the |xdv2pdf| driver can only select fonts +% by name and not by file name. The |xdvipdfmx| driver is default for \XeTeX; +% the |xdv2pdf| driver is only available on \MacOSX. +% +% Fonts selected by filename must include bold and italic variants explicitly. +% \begin{Verbatim} +% \fontspec +% [ BoldFont = texgyrepagella-bold.otf , +% ItalicFont = texgyrepagella-italic.otf , +% BoldItalicFont = texgyrepagella-bolditalic.otf ] +% {texgyrepagella-regular.otf} +% \end{Verbatim} +% \pkg{fontspec} knows that the font is to be selected by file name by the +% presence of the `|.otf|' extension. +% An alternative is to specify the extension separately, as shown following: +% \begin{Verbatim} +% \fontspec +% [ Extension = .otf , +% BoldFont = texgyrepagella-bold , +% ... ] +% {texgyrepagella-regular} +% \end{Verbatim} +% If desired, an abbreviation can be applied to the font names based on the +% mandatory `font name' argument: +% \begin{Verbatim} +% \fontspec +% [ Extension = .otf , +% UprightFont = *-regular , +% BoldFont = *-bold , +% ... ] +% {texgyrepagella} +% \end{Verbatim} +% In this case `texgyrepagella' is no longer the name of an actual font, +% but is used to construct the font names for each shape; +% the |*| is replaced by `texgyrepagella'. +% Note in this case that |UprightFont| is required for constructing the font +% name of the normal font to use. +% +% To load a font that is not in one of the default search paths, its location +% in the filesystem must be specified with the |Path| feature: +% \begin{Verbatim} +% \fontspec +% [ Path = /Users/will/Fonts/ , +% UprightFont = *-regular , +% BoldFont = *-bold , +% ... ] +% {texgyrepagella} +% \end{Verbatim} +% Note that \XeTeX\ and \LuaTeX\ are able to load the font without giving an +% extension, but \pkg{fontspec} must know to search for the file; this can can +% be indicated by declaring the font exists in an `|ExternalLocation|': +% \begin{Verbatim} +% \fontspec +% [ ExternalLocation , +% BoldFont = texgyrepagella-bold , +% ... ] +% {texgyrepagella-regular} +% \end{Verbatim} +% To be honest, |Path| and |ExternalLocation| are actually the same feature +% with different names. The former can be given without an argument and the +% latter can be given with one; the different names are just for clarity. +% +% +% \section{Default font families} +% \label{sec:setxxfont} +% +% \cmdbox{ +% \cmd{\setmainfont} \oarg{font features} \marg{font name} \\ +% \cmd{\setsansfont} \oarg{font features} \marg{font name} \\ +% \cmd{\setmonofont} \oarg{font features} \marg{font name} +% } +% +% These commands are used to select +% the default font families for the entire document. They take the +% same arguments as \cmd{\fontspec}. For example: +% \def\pangram{Pack my box with five +% dozen liquor jugs.} +% \begin{example} +% \setmainfont{Baskerville} +% \setsansfont[Scale=MatchLowercase]{Skia} +% \setmonofont[Scale=MatchLowercase]{Monaco} +% \rmfamily\pangram\par +% \sffamily\pangram\par +% \ttfamily\pangram +% \end{example} +% Here, the scales of the fonts have been chosen to equalise their +% lowercase letter heights. The \feat{Scale} font feature will be discussed +% further in \vref{sec:font-ind-features}, including methods for automatic +% scaling. +% +% +% +% \section{New commands to select font families} +% +% \cmdbox{ +% \CMD{\string\newfontfamily} \cs{\meta{font-switch}} \oarg{font features} \marg{font name} \\ +% \CMD{~~\string\newfontface} \cs{\meta{font-switch}} \oarg{font features} \marg{font name} +% } +% +% \noindent For cases when a specific font with a specific +% feature set is going to be re-used many times in a document, it is inefficient +% to keep calling \cs{fontspec} for every use. While the command does not define +% a new font instance after the first call, the feature options must still be +% parsed and processed. +% +% \DescribeMacro{\newfontfamily} +% For this reason, new commands can be created for loading a particular font +% family with the \cmd\newfontfamily\ command: +% \begin{example} +% \newfontfamily\notefont{Didot} +% \notefont This is a \emph{note}. +% \end{example} +% This macro should be used to create commands that would be used in +% the same way as \cmd\rmfamily, for example. +% +% \DescribeMacro{\newfontface} +% Sometimes only a specific font face is desired, without accompanying italic or bold variants +% begin automatically selected. +% This is common when selecting a fancy italic font, say, that has swash features unavailable +% in the upright forms. \cmd\newfontface\ is used for this purpose: +% \begin{example} +% \newfontface\fancy +% [Contextuals={WordInitial,WordFinal}] +% {Hoefler Text Italic} +% \fancy where is all the vegemite +% \end{example} +% \noindent This example is repeated in \vref{sec:contextuals}. +% +% \subsection{More control over font shape selection} +% \label{sec:bfitfonts} +% +% \cmdbox{ +% \feat{~~~~~~~BoldFont} = \meta{font name} \\ +% \feat{~~~~~ItalicFont} = \meta{font name} \\ +% \feat{~BoldItalicFont} = \meta{font name} \\ +% \feat{~~~~SlantedFont} = \meta{font name} \\ +% \feat{BoldSlantedFont} = \meta{font name} \\ +% \feat{~~SmallCapsFont} = \meta{font name} +% } +% +% The automatic bold, italic, and bold italic font selections will not be +% adequate for the needs of every font: while some fonts mayn't even +% have bold or italic shapes, in which case a skilled (or lucky) +% designer may be able to chose well-matching accompanying shapes from +% a different font altogether, others can have a range of bold and +% italic fonts to chose between. The \feat{BoldFont} and +% \feat{ItalicFont} features are provided for these situations. If only +% one of these is used, the bold italic font is requested as the +% default from the \emph{new} font. +% \begin{example} +% \fontspec[BoldFont={Helvetica Neue}] +% {Helvetica Neue UltraLight} +% Helvetica Neue UltraLight \\ +% {\itshape Helvetica Neue UltraLight Italic} \\ +% {\bfseries Helvetica Neue } \\ +% {\bfseries\itshape Helvetica Neue Italic} \\ +% \end{example} +% If a bold italic shape is not defined, or you want to specify +% \emph{both} custom bold and italic shapes, the \feat{BoldItalicFont} +% feature is provided. +% +% \subsubsection{Input shorthands} +% +% For those cases that the base font name is repeated, you can +% replace it with an asterisk. For example, +% some space can be saved instead of writing `\texttt{Baskerville SemiBold}': +% \begin{example} +% \fontspec[BoldFont={* SemiBold}]{Baskerville} +% Baskerville \textit{Italic} +% \bfseries SemiBold \textit{Italic} +% \end{example} +% +% As a matter of fact, this feature can also be used for the upright font too: +% \begin{example} +% \fontspec[UprightFont={* SemiBold}, +% BoldFont={* Bold}]{Baskerville} +% Upright \textit{Italic} +% \bfseries Bold \textit{Bold Italic} +% \end{example} +% +% \subsubsection{Small caps and slanted font shapes} +% +% For the rare situations where a font family will have slanted \emph{and} +% italic shapes, these may be specified separately using the analogous +% features \feat{SlantedFont} and \feat{BoldSlantedFont}. Without these, +% however, the \LaTeX\ font switches for slanted (\cs{textsl}, \cs{slshape}) +% will default to the italic shape. +% +% Old-fashioned font families used to distribute their small caps +% glyphs in separate fonts due to the limitations on the number +% of glyphs allowed in the PostScript Type~1 format. Such fonts may be used +% by declaring the \feat{SmallCapsFont} of the family you are specifying: +% \begin{Verbatim} +% \fontspec[ +% SmallCapsFont={Minion MM Small Caps & Oldstyle Figures}, +% ]{Minion MM Roman} +% Roman 123 \\ \textsc{Small caps 456} +% \end{Verbatim} +% +% All of the bold, italic, and small caps fonts can be loaded with different +% font features from the main font. See \ref{bfit-feat} for details. +% +% \subsection{Math(s) fonts} +% +% When \cmd\setmainfont, \cmd\setsansfont\ and \cmd\setmonofont\ are used in the +% preamble, they also define the fonts to be used in maths mode inside the +% \cmd\mathrm-type commands. This only occurs in the preamble because \LaTeX\ +% freezes the maths fonts after this stage of the processing. The \pkg{fontspec} +% package must also be loaded after any maths font packages (\eg, \pkg{euler}) +% to be successful. (Actually, it is \emph{only} \pkg{euler} that is the +% problem.\footnote{Speaking of \pkg{euler}, if you want to use its +% \texttt{[mathbf]} option, it won't work, and you'll need to put this after +% \pkg{fontspec} is loaded instead: +% \ttfamily\cmd\AtBeginDocument\char`\{\cmd\DeclareMathAlphabet\cmd\mathbf\char`\{U\char`\}\char`\{eur\char`\}\char`\{b\char`\}\char`\{n\char`\}}) +% +% Note that you may find that loading some maths packages won't be as smooth as +% you expect since \pkg{fontspec} (and \XeTeX\ in general) breaks many of the +% assumptions of \TeX\ as to where maths characters and accents can be found. +% Contact me if you have troubles, but I can't guarantee to be able to fix any +% incompatibilities. The Lucida and Euler maths fonts should be fine; for all +% others keep an eye out for problems. +% +% \cmdbox{ +% \cmd{\setmathrmfont} \oarg{font features} \marg{font name} \\ +% \cmd{\setmathsffont} \oarg{font features} \marg{font name} \\ +% \cmd{\setmathttfont} \oarg{font features} \marg{font name} \\ +% \cmd{\setboldmathrmfont} \oarg{font features} \marg{font name} +% } +% +% However, the default text fonts may not necessarily be the ones you +% wish to use when typesetting maths (especially with the use of fancy +% ligatures and so on). For this reason, you may optionally use those +% commands listed in the margin (in the same way as our other +% \cmd\fontspec-like commands) to explicitly state which fonts to use +% inside such commands as \cmd\mathrm. Additionally, the +% \cmd\setboldmathrm\ command allows you define the font used for +% \cmd\mathrm\ when in bold maths mode (which is activated with, among +% others, \cmd\boldmath). +% +% For example, if you were using Optima with the Euler maths font, you +% might have this in your preamble: +% \begin{Verbatim} +% \usepackage{mathpazo} +% \usepackage{fontspec,xunicode} +% \setmainfont{Optima} +% \setmathrm{Optima} +% \setboldmathrm[BoldFont=Optima ExtraBlack]{Optima Bold} +% \end{Verbatim} +% and this would allow you to typeset something like this: +% \begin{example} +% \setmainfont{Optima Regular} +% $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $ +% \\\boldmath +% $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $ +% \end{example} +% (TODO: this example obviously doesn't work without the graphic.) +% +% +% \subsection{Miscellaneous font selecting details} +% +% \paragraph{Spaces} +% \cmd\fontspec\ and \cmd\addfontfeatures\ ignore trailing spaces as +% if it were a `naked' control sequence; \eg, `|M. \fontspec{...} N|' and +% `|M. \fontspec{...}N|' are the same. +% +% \paragraph{Italic small caps} +% Note that this package redefines the \cs{itshape} and \cs{scshape} +% commands in order to allow them to select italic small caps in +% conjunction. +% +% \paragraph{Emphasis and nested emphasis} +% You may specify the behaviour of the \cs{emph} command by setting the +% \cs{emshape} command. \Eg, for bold emphasis:\par +% \indent|\renewcommand\emshape{\bfseries}|\par\noindent +% Nested emphasis is controlled by the \cs{eminnershape} command. +% For example, for |\emph{\emph{...}}| to produce small caps:\par +% \indent|\renewcommand\eminnershape{\scshape}|\par\noindent +% \XeTeX\ users will need to load the \pkg{xltxtra} package before the +% advice above works. +% +% +% +% +% +% \section{Selecting font features} +% \label{sec:selectingfeature} +% +% The commands discussed so far each take an optional argument for +% accessing the font features of the requested font. These features +% are generally unavailable or harder to access in regular \LaTeX. +% +% \subsection{Default settings} \label{sec:defaults} +% +% \cmdbox{\cmd\defaultfontfeatures \marg{font features}} +% +% It is desirable to define +% options that are applied to every subsequent font selection command: +% a default feature set, so to speak. This may be defined with the +% \cmd{\defaultfontfeatures} command. +% New calls of \cs{defaultfontfeatures} overwrite previous ones. +% \begin{example} +% \fontspec{Didot} +% Some `default' Didot 0123456789 \\ +% \defaultfontfeatures{Numbers=OldStyle, Color=888888} +% \fontspec{Didot} +% Now grey, with old-style figures: 0123456789 +% \end{example} +% +% \subsection{Changing the currently selected features} +% \label{sec:addfontfeatures} +% +% \cmdbox{\cmd\addfontfeatures \marg{font features}} +% +% This command allows font features to +% be changed without knowing what features are currently selected or even what +% font is being used.

It allows different fonts +% and different font features to be selected for a given font +% family as the point size varies. +% +% It takes a comma separated list of braced, comma separated lists of features for each size range. +% Each sub-list must contain the \opt{Size} option +% to declare the size range, and optionally \opt{Font} to change the +% font based on size. Other (regular) fontspec features that are added +% are used on top of the font features that would be used anyway. +% +% \begin{example} +% \fontspec[ SizeFeatures={ +% {Size={-8}, Font=Apple Chancery, Color=AA0000}, +% {Size={8-14}, Color=00AA00}, +% {Size={14-}, Color=0000AA}} ]{Skia} +% {\scriptsize Small\par} Normal size\par {\Large Large\par} +% \end{example} +% A less trivial example is shown in the context of optical font sizes +% in \vref{sec:opticalsize}. +% +% To be precise, the \opt{Size} sub-feature accepts arguments in the form shown in \vref{tab:sizing}. +% Braces around the size range are optional. For an exact font size (|Size=X|) +% font sizes chosen near that size will `snap'. For example, for size definitions +% at exactly 11pt and 14pt, if a 12pt font is requested \emph{actually} the +% 11pt font will be selected. This is a remnant of the past when fonts were designed +% in metal (at obviously rigid sizes) and later when bitmap fonts were similarly +% designed for fixed sizes. +% +% If additional features are only required for a single size, the other sizes +% must still be specified. As in: +% \begin{verbatim} +% SizeFeatures={ +% {Size=-10,Numbers=Uppercase}, +% {Size=10-}} +% \end{verbatim} +% Otherwise, the font sizes greater than 10 won't be defined! +% +% \begin{table} +% \centering +% \begin{tabular}{@{}ll@{}} +% \toprule +% Input & Font size, $s$ \\ +% \midrule +% |Size = X-| & $s \geq \texttt{X}$ \\ +% |Size = -Y| & $s < \texttt{Y}$ \\ +% |Size = X-Y| & $\texttt{X} \leq s < \texttt{Y}$ \\ +% |Size = X| & $s = \texttt{X}$ \\ +% \bottomrule +% \end{tabular} +% \caption{Syntax for specifying the size to apply custom font features.}\label{tab:sizing} +% \end{table} +% +% +% \section{Font independent options} \label{sec:font-ind-features} +% +% Features introduced in this section may be used with any font. +% +% \subsection{Color} +% +% \feat{Color} (or \feat{Colour}), also shown in \vref{sec:defaults} +% and elsewhere, uses \XeTeX\ font specifications to set the color of +% the text. The color is defined as a triplet of two-digit Hex RGB +% values, with optionally another value for the transparency (where +% |00| is completely transparent and |FF| is opaque.) +% \begin{example} +% \fontsize{48}{48} +% \fontspec{Hoefler Text Black} +% {\addfontfeature{Color=FF000099}W}\kern-1ex +% {\addfontfeature{Color=0000FF99}S}\kern-0.8ex +% {\addfontfeature{Color=DDBB2299}P}\kern-0.8ex +% {\addfontfeature{Color=00BB3399}R} +% \end{example} +% +% \subsection{Scale} +% +% \cmdbox{ +% \feat{Scale} = \meta{number} \\ +% \feat{Scale} = \opt{MatchLowercase} \\ +% \feat{Scale} = \opt{MatchUppercase} +% } +% +% In its explicit form, \feat{Scale} takes a single +% numeric argument for linearly scaling the font, as demonstrated +% in \vref{sec:setxxfont}. +% It is now possible to +% measure the correct dimensions of the fonts loaded and +% calculate values to scale them automatically. +% +% As well as a numerical argument, \feat{Scale} feature +% also accepts options \opt{MatchLowercase} +% and \opt{MatchUppercase}, which will scale the font being selected to match +% the current default roman font to either the height of the lowercase or +% uppercase letters, respectively. +% \begin{example} +% \setmainfont{Georgia} +% \newfontfamily\lc[Scale=MatchLowercase]{Verdana} +% The perfect match {\lc is hard to find.}\\ +% \newfontfamily\uc[Scale=MatchUppercase]{Arial} +% L O G O \uc F O N T +% \end{example} +% The amount of scaling used in each instance is reported in the \texttt{.log} file. +% Since there is some subjectivity about the exact scaling to be used, these values +% should be used to fine-tune the results. +% +% +% +% +% \subsection{Interword space} +% +% While the space between words can be varied on an individual +% basis with the \TeX\ primitive \cmd\spaceskip\ command, it is +% more convenient to specify this information when the font is +% first defined. +% +% The space in between words in a paragraph will be chosen automatically +% by \XeTeX, and generally will not need to be adjusted. For those +% times when the precise details are important, the \feat{WordSpace} +% features is +% provided, which takes either a single scaling factor to scale the +% value that \XeTeX\ has already chosen, or a triplet of comma-separated +% values for the nominal value, the stretch, and the shrink of the +% interword space, respectively. \Ie, |WordSpace=0.8| is the same as +% |WordSpace={0.8,0.8,0.8}|. +% +% For example, I believe that the Cochin font, as distributed with \MacOSX, +% is too widely spaced. Now, this can be rectified, as shown below. +% \begingroup +% \let\centering\relax +% \def\fillertext{Some filler text for our example to take up some +% space, and to demonstrate the large default interword space in \textit{Cochin}.} +% \begin{example} +% \fontspec{Cochin} +% \fillertext +% \vspace{1em} +% +% \fontspec[ WordSpace = {0.7 , 0.8 , 0.9} ]{Cochin} +% \fillertext +% \end{example} +% \endgroup +% Be careful with the unpredictable things that the \AAT\ font renderer +% can do with the text! Unlike \TeX, \MacOSX\ will allow +% fonts to letterspace themselves, which can be seen above; OpenType fonts, however, will not +% show this tendency, as they do not support this arguably dubious feature. +% +% \subsection{Post-punctuation space} +% +% If \cmd\frenchspacing\ is \emph{not} in effect, \TeX\ will allow extra +% space after some punctuation in its goal of justifying the lines of text. +% Generally, this is considered old-fashioned, but occasionally in small amounts the +% effect can be justified, pardon the pun. +% +% The \feat{PunctuationSpace} feature takes a scaling factor by which to +% adjust the nominal value chosen for the font. Note that |PunctuationSpace=0| +% is \emph{not} equivalent to \cmd\frenchspacing, although the difference +% will only be apparent when a line of text is under-full. +% \begingroup +% \let\centering\relax +% \begin{example} +% \nonfrenchspacing +% \fontspec{Baskerville} +% Letters, Words. Sentences. \par +% \fontspec[PunctuationSpace=0.5]{Baskerville} +% Letters, Words. Sentences. \par +% \fontspec[PunctuationSpace=0]{Baskerville} +% Letters, Words. Sentences. +% \end{example} +% \endgroup +% +% Also be aware that the above caveat for interword space also applies here, +% so after the last line in the above example, the \feat{PunctuationSpace} +% for \emph{all} Baskerville instances will be |0|. +% +% +% +% +% \subsection{The hyphenation character} +% +% The letter used for hyphenation may be chosen with the \feat{HyphenChar} +% feature. It takes three types of input, which are chosen according to some +% simple rules. If the input is the string \opt{None}, then hyphenation is +% suppressed for this font. If the input is a single character, then this +% character is used. Finally, if the input is longer than a single character +% it must be the UTF-8 slot number of the hyphen character you desire. +% +% Below, Adobe Garamond Pro's uppercase hyphenation character +% is used to demonstrate a possible use for this feature. +% The second example redundantly demonstrates the default behaviour +% of using the hyphen as the hyphenation character. +% \begingroup +% \let\centering\relax +% \begin{example} +% \def\text +% {A MULTITUDE OF OBSTREPEROUSLY HYPHENATED ENTITIES +% \par\vspace{1ex}} +% \fontspec[HyphenChar=None]{Adobe Garamond Pro} \text +% \fontspec[HyphenChar={-}]{Adobe Garamond Pro} \text +% \fontspec[HyphenChar="F6BA]{Adobe Garamond Pro} \text +% \end{example} +% \endgroup +% Note that in an actual situation, the \opt{Uppercase} option of the \feat{Letters} feature +% would probably supply this for you (see \vref{sec:letters}). +% +% This package (or the \pkg{xltxtra} package for \XeTeX\ users) +% redefines \LaTeX's \cmd\-\ macro +% such that it adjusts along with the above changes. +% +% +% \subsection{Optical font sizes} \label{sec:opticalsize} +% +% Optically scaled fonts thicken out as the font size decreases +% in order to make the glyph shapes more robust (less prone to losing +% detail), which improves legibility. Conversely, at large optical +% sizes the serifs and other small details may be more delicately +% rendered. +% +% OpenType fonts with optical scaling will exist in +% several discrete sizes, and these will be selected by \XeTeX\ +% \emph{automatically} determined by the current font size. The +% \opt{OpticalSize} option may be used to specify a different optical +% size. +% +% For the OpenType font Warnock Pro, we have three optically sized +% variants: caption, subhead, and display. With \opt{OpticalSize} set +% to zero, no optical size font substitution is performed: +% \begin{opentypeexample} +% \fontspec[OpticalSize=0]{Warnock Pro Caption} +% Warnock Pro optical sizes \\ +% \fontspec[OpticalSize=0]{Warnock Pro} +% Warnock Pro optical sizes \\ +% \fontspec[OpticalSize=0]{Warnock Pro Subhead} +% Warnock Pro optical sizes \\ +% \fontspec[OpticalSize=0]{Warnock Pro Display} +% Warnock Pro optical sizes +% \end{opentypeexample} +% +% Automatic OpenType optical scaling is shown in the following +% example, in which we've scaled down some large text in order to be +% able to compare the difference for equivalent font sizes: (this +% gives the same output as we saw in the previous example for Warnock +% Pro Display) +% \begin{opentypeexample} +% \fontspec{Warnock Pro} +% Automatic optical size \\ +% \scalebox{0.4}{\Huge +% Automatic optical size} +% \end{opentypeexample} +% +% The \feat{SizeFeatures} feature (\vref{sec:sizefeature}) can be +% used to specify exactly which optical sizes will be used for ranges +% of font size. For example, something like +% \begin{verbatim} +% \fontspec[ +% SizeFeatures={ +% {Size=-10, OpticalSize=8 }, +% {Size= 10-14, OpticalSize=10}, +% {Size= 14-18, OpticalSize=14}, +% {Size= 18-, OpticalSize=18}} +% ]{Warnock Pro} +% \end{verbatim} +% +% \clearpage +% \part{OpenType} +% \label{sec:opentype-features} +% +% \section{Introduction} +% +% TODO: explain OpenType font features. +% +% Some examples of font features have already be seen in previous +% sections. +% +% Multiple options may be given to +% any feature that accepts non-numerical input, although doing so will +% not always work. Some options will override others in generally +% obvious ways; \Verb|Numbers={OldStyle,Lining}| doesn't make much +% sense because the two options are mutually exclusive, and \XeTeX\ +% will simply use the last option that is specified (in this case +% using \opt{Lining} over \opt{OldStyle}). +% +% If a feature or an option is requested that the font does not have, +% a warning is given in the console output. As mentioned in \vref{sec:quiet-warnings} +% these warnings can be suppressed by selecting the \texttt{[quiet]} package option. +% +% \section{Complete listing of OpenType font features} +% +% \subsection{Ligatures} +% +% \feat{Ligatures} refer to the replacement of two separate characters +% with a specially drawn glyph for functional or \ae sthetic reasons. +% The list of options, of which multiple may be selected at one time, +% is shown in \ref{feat:Ligatures}. +% +% \begin{features}{Ligatures} +% \otf*{Required}{rlig} +% \otf*{Common}{liga} +% \otf*{Contextual}{clig} +% \otf{Rare/Discretionary}{dlig} +% \otf{Historical}{hlig} +% \otf{TeX}{tlig/trep} +% \end{features} +% +% \begin{opentypeexample} +% \fontspec[Ligatures=Rare]{Adobe Garamond Pro} +% \textit{strict firefly} \\ +% \fontspec[Ligatures=NoCommon]{Adobe Garamond Pro} +% \textit{strict firefly} +% \end{opentypeexample} +% +% \subsection{Letters} \label{sec:letters} +% The \opt{Letters} feature specifies how the letters in the current font +% will look.

+% +% The features described here are available for any font +% selected by \pkg{fontspec}. +% +% \subsection{Mapping} +% +% \feat{Mapping} enables a \XeTeX\ text-mapping scheme. +% \begin{example} +% \fontspec[Mapping=tex-text]{Cochin} +% ``!`A small amount of---text!'' +% \end{example} +% Using the |tex-text| mapping is also equivalent to writing |Ligatures=TeX|. +% The use of the latter syntax is recommended for better compatibility with +% \LuaTeX\ documents. +% +% +% \subsection{Letter spacing} +% Letter spacing, or tracking, is the term given to adding (or subtracting) a small amount of horizontal space in between adjacent characters. It is specified with the \feat{LetterSpace}, which takes a numeric argument. +% +% The letter spacing parameter is a normalised additive factor (not a scaling factor); it is defined as a percentage of the font size. That is, for a 10\,pt font, a letter spacing parameter of `|1.0|' will add 0.1\,pt between each letter. +% \begin{example} +% \fontspec{Didot} +% \addfontfeature{LetterSpace=0.0} +% USE TRACKING FOR DISPLAY CAPS TEXT \\ +% \addfontfeature{LetterSpace=2.0} +% USE TRACKING FOR DISPLAY CAPS TEXT +% \end{example} +% This functionality \emph{should not be used for lowercase text}, which is spacing correctly to begin with, but it can be very useful, in small amounts, when setting small caps or all caps titles. +% Also see the OpenType \opt{Uppercase} +% option of the \feat{Letters} feature (\vref*{sec:letters}). +% +% \subsection{Font transformations} +% +% In rare situations users may want to mechanically distort the shapes of the glyphs in the current font. Please don't overuse these features; they can be extremely ugly if overused. +% +% \begin{example} +% \fontspec{Charis SIL} \emph{ABCxyz} \quad +% \fontspec[FakeSlant=0.2]{Charis SIL} ABCxyz +% \end{example} +% +% \begin{example} +% \fontspec{Charis SIL} ABCxyz \quad +% \fontspec[FakeStretch=1.2]{Charis SIL} ABCxyz +% \end{example} +% +% \begin{example} +% \fontspec{Charis SIL} \textbf{ABCxyz} \quad +% \fontspec[FakeBold=1.5]{Charis SIL} ABCxyz +% \end{example} +% +% If values are omitted, their defaults are as shown above. +% +% +% \subsection{Different font technologies: \AAT\ and ICU}\label{sec:renderer} +% +% \XeTeX\ supports two rendering technologies for typesetting, selected with +% the \feat{Renderer} font feature. The first, \opt{AAT}, is +% that provided (only) by \MacOSX\ itself. The second, \opt{ICU}, +% is an open source OpenType interpreter. It provides much greater support for +% OpenType features, notably contextual arrangement, over \opt{AAT}. +% +% In general, this feature will not need to be explicitly called: for OpenType +% fonts, the \opt{ICU} renderer is used automatically, and for \AAT\ fonts, +% \opt{AAT} is chosen by default. Some fonts, however, will contain font tables +% for \emph{both} rendering technologies, such as the Hiragino Japanese fonts +% distributed with \MacOSX, and in these cases the choice may be required. +% +% Among some other font features only available through a specific renderer, +% \opt{ICU} provides for the \feat{Script} and \feat{Language} features, which allow +% different font behaviour for different alphabets and languages; see \vref{sec:ot} +% for the description of these features. {\em Because these font features can +% change which features are able to be selected for the font instance, they are selected +% by \pkg{fontspec} before all others and will automatically and without warning +% select the \opt{ICU} renderer.} +% +% +% \subsection{Optical font sizes} \label{sec:opticalsize} +% +% Multiple Master fonts are parameterised over +% orthogonal font axes, allowing continuous selection along such +% features as weight, width, and optical size~(see \vref{sec:mm} for +% further details). Whereas an OpenType font will have only a few separate +% optical sizes, a Multiple Master font's optical size can be +% specified over a continuous range. Unfortunately, this flexibility makes +% it harder to create an automatic interface through \LaTeX, and the +% optical size for a Multiple Master font must always be specified +% explicitly. +% \begin{Verbatim} +% \fontspec[OpticalSize=11]{Minion MM Roman} +% MM optical size test \\ +% \fontspec[OpticalSize=47]{Minion MM Roman} +% MM optical size test \\ +% \fontspec[OpticalSize=71]{Minion MM Roman} +% MM optical size test \\ +% \end{Verbatim} +% +% +% +% +% \section{\MacOSX's \AAT\ fonts} +% \label{sec:aat-features} +% +% \MacOSX's font technology began life before the ubiquitous-OpenType era +% and revolved around the Apple-invented `\AAT' font format. This format +% had some advantages (and other disadvantages) but it never became widely +% popular in the font world. +% +% Nonetheless, this is the font format that was first supported by \XeTeX\ +% (due to its pedigree on \MacOSX\ in the first place) and was the first +% font format supported by \pkg{fontspec}. A number of fonts distributed with +% \MacOSX\ are still in the \AAT\ format, such as `Skia'. Documents +% that use these fonts should be compiled with \XeLaTeX\ using the +% \texttt{xdv2pdf} driver, as opposed to the default \texttt{xdvipdfmx}. E.g., +% \begin{verbatim} +% xelatex -output-driver="xdv2pdf" filename.tex +% \end{verbatim} +% +% \MacOSX\ also supports Multiple Master fonts, which are discussed +% in \ref{sec:mm}. +% +% \subsection{Ligatures} +% +% \feat{Ligatures} refer to the replacement of two separate characters +% with a specially drawn glyph for functional or \ae sthetic reasons. +% For \AAT\ fonts, you may choose from any combination of \opt{Required}, +% \opt{Common}, \opt{Rare} (or \opt{Discretionary}), \opt{Logos}, \opt{Rebus}, +% \opt{Diphthong}, \opt{Squared}, \opt{AbbrevSquared}, and \opt{Icelandic}. +% +% Some other Apple \AAT\ fonts have those `Rare' ligatures contained in +% the \opt{Icelandic} feature. Notice also that the old \TeX\ trick of +% splitting up a ligature with an empty brace pair does not work in +% \XeTeX; you must use a 0\,pt kern or \cs{hbox} (\eg, \cs{null}) to +% split the characters up. +% +% \subsection{Letters} \label{sec:letters} +% The \opt{Letters} feature specifies how the letters in the current font +% will look. For \AAT\ fonts, you may choose from \opt{Normal}, +% \opt{Uppercase}, \opt{Lowercase}, \opt{SmallCaps}, and +% \opt{InitialCaps}. +% +% +% \subsection{Numbers} +% The \feat{Numbers} feature defines how numbers will look in the +% selected font. For both \AAT, they may be a +% combination of \opt{Lining} or \opt{OldStyle} and \opt{Proportional} or +% \opt{Monospaced} (the latter is good for tabular material). The synonyms +% \opt{Uppercase} and \opt{Lowercase} are equivalent to \opt{Lining} and +% \opt{OldStyle}, respectively. The differences have been shown previously +% in \vref{sec:addfontfeatures}. +% +% \subsection{Contextuals} \label{sec:contextuals} +% This feature refers to glyph substitution that vary by their position; +% things like contextual swashes are implemented here +% The options for \AAT\ fonts are +% \opt{WordInitial}, \opt{WordFinal}, \opt{LineInitial}, +% \opt{LineFinal}, and \opt{Inner} (also called `non-final' sometimes). As +% non-exclusive selectors, like the ligatures, you can turn them off +% by prefixing their name with \opt{No}. +% \begin{aatexample} +% \newfontface\fancy +% [Contextuals={WordInitial,WordFinal}] +% {Hoefler Text Italic} +% \fancy where is all the vegemite +% \end{aatexample} +% \begin{aatexample} +% \fontspec[Contextuals=Inner]{Hoefler Text} +% `Inner' swashes can \emph{sometimes} \\ +% contain the archaic long~s. +% \end{aatexample} +% +% +% \subsection{Vertical position} +% The \feat{VerticalPosition} feature is used to access things like +% subscript (\opt{Inferior}) and superscript (\opt{Superior}) numbers and +% letters (and a small amount of punctuation, sometimes). +% The \opt{Ordinal} option is (supposed to be) +% contextually sensitive to only raise characters that appear directly +% after a number. +% \begin{aatexample} +% \fontspec{Skia} +% Normal +% \fontspec[VerticalPosition=Superior]{Skia} +% Superior +% \fontspec[VerticalPosition=Inferior]{Skia} +% Inferior \\ +% \fontspec[VerticalPosition=Ordinal]{Skia} +% 1st 2nd 3rd 4th 0th 8abcde +% \end{aatexample} +% +% The \pkg{xltxtra} package redefines the \cmd\textsubscript\ and +% \cmd\textsuperscript\ commands to use the above font features. +% +% \subsection{Fractions} +% Many fonts come with the capability to typeset various forms of +% fractional material. This is accessed in \pkg{fontspec} with the +% \feat{Fractions} feature, which may be turned \opt{On} or \opt{Off} +% in both \AAT\ and OpenType fonts. +% +% In \AAT\ fonts, the `fraction slash' or solidus character, is +% to be used to create fractions. When \feat{Fractions} are turned +% \opt{On}, then only pre-drawn fractions will be used. +% \begin{aatexample} +% \fontspec[Fractions=On]{Skia} +% 1⁄2 \quad 5⁄6 \\ % fraction slash +% 1/2 \quad 5/6 % regular slash +% \end{aatexample} +% Using the \opt{Diagonal} option (\AAT\ only), the font will attempt +% to create the fraction from superscript and subscript +% characters. This is shown in the following example: +% \begin{aatexample} +% \fontspec[Fractions=Diagonal]{Skia} +% 13579⁄24680 \\ % fraction slash +% \quad 13579/24680 % regular slash +% \end{aatexample} +% +% Some (Asian fonts predominantly) also provide for the +% \opt{Alternate} feature: +% \begin{opentypeexample} +% \fontspec{Hiragino Maru Gothic Pro W4} +% 1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\ +% \addfontfeature{Fractions=Alternate} +% 1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\ +% \end{opentypeexample} +% The \pkg{xltxtra} package provides a \cmd\vfrac\ command +% for creating arbitrary so-called `vulgar' fractions: +% \begin{opentypeexample} +% \fontspec{Warnock Pro} +% \vfrac{13579}{24680} +% \end{opentypeexample} +% +% +% \subsection{Variants} +% The \feat{Variant} feature takes a single numerical input for +% choosing different alphabetic shapes. Don't mind my fancy example +% \texttt{:)} I'm just looping through the nine~(\,!\,) variants of +% Zapfino. +% \setexsize\Huge +% \def\firstline{2}\def\lastline{9} +% \begin{aatexample} +% \rule{0pt}{2cm}% % \newcounter{var}\newcounter{trans} +% \whiledo{\value{var}<9}{% % \stepcounter{trans}% % \fontspec[Variant=\thevar, +% Color=005599\thetrans\thetrans]{Zapfino}% % \makebox[0.75\width]{d}% % \stepcounter{var}} +% \end{aatexample} +% +% See \vref{sec:newfeatures} for a way to assign names to variants, +% which should be done on a per-font basis. +% +% \subsection{Alternates} +% +% Selection of \feat{Alternate}s \emph{again} +% must be done numerically. Here's an example with an \AAT\ font: +% \begin{aatexample} +% \fontspec[Alternate=0]{Hoefler Text Italic} +% Sphinx Of Black Quartz, {\scshape Judge My Vow} \\ +% \fontspec[Alternate=1]{Hoefler Text Italic} +% Sphinx Of Black Quartz, {\scshape Judge My Vow} +% \end{aatexample} +% See \vref{sec:newfeatures} for a way to assign names to alternates, +% which should be done on a per-font basis. +% +% +% \subsection{Style} +% The options of the \feat{Style} feature +% are defined in \AAT\ as one of the following: \opt{Display}, +% \opt{Engraved}, \opt{IlluminatedCaps}, \opt{Italic}, +% \opt{Ruby},\footnotemark\ \opt{TallCaps}, or \opt{TitlingCaps}. +% \footnotetext{`Ruby' refers to a small optical size, used in +% Japanese typography for annotations.} +% +% \setexsize\Large +% \begin{opentypeexample} +% \fontspec{Warnock Pro} +% K Q R k v w y \\ +% \addfontfeature{Style=Alternate} +% K Q R k v w y +% \end{opentypeexample} +% Note the occasional inconsistency with which font features are labelled; a long-tailed `Q' could turn up anywhere! +% \setexsize\Large +% \begin{opentypeexample} +% \fontspec{Adobe Jenson Pro} +% M Q Z \\ +% \addfontfeature{Style=Historic} +% M Q Z +% \end{opentypeexample} +% \setexsize\Large +% \begin{example} +% \fontspec{Adobe Garamond Pro} +% TITLING CAPS \\ +% \addfontfeature{Style=TitlingCaps} +% TITLING CAPS +% \end{example} +% Two features in one example; \opt{Italic} affects the Latin text and \opt{Ruby} the Japanese: +% \setexsize\Large +% \begin{opentypeexample} +% \fontspec{Hiragino Mincho Pro W3} +% Latin ようこそ ワカヨタレソ \\ +% \addfontfeature{Style={Italic, Ruby}} +% Latin ようこそ ワカヨタレソ +% \end{opentypeexample} +% Note the difference here between the default and the horizontal style kana: +% \setexsize\Large +% \begin{aatexample} +% \fontspec{Hiragino Mincho Pro} +% ようこそ ワカヨタレソ \\ +% {\addfontfeature{Style=HorizontalKana} +% ようこそ ワカヨタレソ} \\ +% {\addfontfeature{Style=VerticalKana} +% ようこそ ワカヨタレソ} +% \end{aatexample} +% +% +% +% +% +% \subsection{CJK shape} +% There have been many standards for how CJK ideographic +% glyphs are `supposed' to look. Some fonts will contain many alternate +% glyphs available in order to be able to display these gylphs +% correctly in whichever form is appropriate. Both \AAT\ and OpenType +% fonts support the following \feat{CJKShape} options: +% \opt{Traditional}, \opt{Simplified}, \opt{JIS1978}, \opt{JIS1983}, +% \opt{JIS1990}, and \opt{Expert}. OpenType also supports the \opt{NLC} option. +% +% \subsection{Character width}\label{sec:CharacterWidth} +% Many Asian fonts are equipped with variously spaced characters for +% shoe-horning into their generally monospaced text. +% These are +% accessed through the \feat{CharacterWidth} feature. +% \note{Apple +% seems to be adapting its \AAT\ features in this regard (at least in +% the fonts it distributes with \MacOSX) to have a one-to-one +% correspondence with the equivalent OpenType features. Previously +% \AAT\ was more fine grained, but naturally they're not documenting +% their \AAT\ tables any more, so if the following features don't work +% for a specific font let me know and I'll try and see if anything +% can be salvaged from the situation.} +% For now, OpenType and \AAT\ +% share the same six options for this feature: \opt{Proportional}, +% \opt{Full}, \opt{Half}, \opt{Third}, +% \opt{Quarter}, \opt{AlternateProportional}, and +% \opt{AlternateHalf}. \AAT\ also allows \opt{Default} to return to +% whatever was originally specified. +% +% Japanese alphabetic glyphs (in Hiragana or Katakana) may be typeset +% proportionally, to better fit horizontal measures, or monospaced, to +% fit into the rigid grid imposed by ideographic typesetting. In this +% latter case, there are also half-width forms for squeezing more kana +% glyphs (which are less complex than the kanji they are amongst) into +% a given block of space. The same features are given to roman letters +% in Japanese fonts, for typesetting foreign words in the same style +% as the surrounding text. +% \begin{opentypeexample} +% \def\test{\makebox[2cm][l]{ようこそ}% % \makebox[2.5cm][l]{ワカヨタレソ}% % \makebox[2.5cm][l]{abcdef}} +% \fontspec{Hiragino Mincho Pro} +% {\addfontfeature{CharacterWidth=Proportional}\test}\\ +% {\addfontfeature{CharacterWidth=Full}\test}\\ +% {\addfontfeature{CharacterWidth=Half}\test} +% \end{opentypeexample} +% The same situation occurs with numbers, which are provided in +% increasingly illegible compressed forms: +% \setexsize\large +% \begin{aatexample} +% \fontspec[Renderer=AAT]{Hiragino Mincho Pro} +% {\addfontfeature{CharacterWidth=Full} +% ---12321---}\\ +% {\addfontfeature{CharacterWidth=Half} +% ---1234554321---}\\ +% {\addfontfeature{CharacterWidth=Third} +% ---123456787654321---}\\ +% {\addfontfeature{CharacterWidth=Quarter} +% ---12345678900987654321---} +% \end{aatexample} +% The option \opt{CharacterWidth=Full} doesn't work with the +% default OpenType font renderer (ICU) due to a bug in the Hiragino fonts. +% +% +% \subsection{Annotation} +% Various Asian fonts are equipped with a more extensive range of +% numbers and numerals in different forms. +% For OpenType fonts, the only option supported is \opt{On} and \opt{Off}: +% \begin{opentypeexample} +% \fontspec{Hiragino Maru Gothic Pro} +% 1 2 3 4 5 6 7 8 9 \\ +% \addfontfeature{Annotation=On} +% 1 2 3 4 5 6 7 8 9 +% \end{opentypeexample} +% I'm not sure if \XeTeX\ can access alternate annotation +% forms, even if they exist (as in this case) in the font. +% +% +% \subsection{Vertical typesetting} +% +% \XeTeX\ provides for vertical typesetting simply with the ability to rotate +% the individual glyphs as a font is used for typesetting. +% +% \begin{aatexample} +% \fontspec{Hiragino Mincho Pro} +% 共産主義者は +% +% \fontspec[Renderer=AAT,Vertical=RotatedGlyphs]{Hiragino Mincho Pro} +% \rotatebox{-90}{共産主義者は}% requires the graphicx package +% \end{aatexample} +% +% No actual provision is made for typesetting top-to-bottom +% languages; for an example of how to do this, see the vertical Chinese +% example provided in the \XeTeX\ documentation. +% +% +% +% +% \subsection{Diacritics} +% Diacritics refer to characters that include extra marks that usually +% indicate pronunciation; \eg, accented letters. You may either choose +% to \opt{Show}, \opt{Hide} or \opt{Decompose} them in \AAT\ fonts. +% +% Some fonts include |O/| \etc\ as diacritics for writing \O. You'll +% want to turn this feature off (imagine typing |hello/goodbye| and +% getting `hell\o goodbye' instead!) by decomposing the two characters +% in the diacritic into the ones you actually +% want. I would recommend using +% the proper \TeX\ input conventions for obtaining such characters +% instead. +% +% The \opt{Hide} option is for Arabic-like fonts which may be +% displayed either with or without vowel markings. +% +% +% \subsection{Annotation} +% Various Asian fonts are equipped with a more extensive range of +% numbers and numerals in different forms. These are accessed through +% the \feat{Annotation} feature with the following options: \opt{Off}, +% \opt{Box}, \opt{RoundedBox}, \opt{Circle}, \opt{BlackCircle}, +% \opt{Parenthesis}, \opt{Period}, \opt{RomanNumerals}, \opt{Diamond}, +% \opt{BlackSquare}, \opt{BlackRoundSquare}, and \opt{DoubleCircle}. +% \begin{aatexample} +% \fontspec{Hei Regular} +% 1 2 3 4 5 6 7 8 9 \\ +% \fontspec[Annotation=Circle]{Hei Regular} +% 1 2 3 4 5 6 7 8 9 \\ +% \fontspec[Annotation=Parenthesis]{Hei Regular} +% 1 2 3 4 5 6 7 8 9 \\ +% \fontspec[Annotation=Period]{Hei Regular} +% 1 2 3 4 5 6 7 8 9 +% \end{aatexample} +% +% \section{\AAT\ \& Multiple Master font axes} \label{sec:mm} +% +% Multiple Master and \AAT\ font specifications both provide continuous +% variation along font parameters. For example, they don't have just +% regular and bold weights, they can have any bold weight you like between +% the two extremes. +% +% \opt{Weight}, \opt{Width}, and \opt{OpticalSize} are supported by this +% package. Skia, which is distributed with +% Mac~OS~X, has two of these variable parameters, allowing for a +% demonstration: +% \begin{aatexample} +% \fontspec[Weight=0.5,Width=3]{Skia} +% Really light and extended Skia \\ +% \fontspec[Weight=2,Width=0.5]{Skia} +% Really fat and condensed Skia +% \end{aatexample} +% Variations along a multiple master font's optical size axis has been +% shown previously in \vref{sec:opticalsize}. +% +% +% \clearpage +% \part{Programming interface} +% +% This is the beginning of some work to provide some hooks that use +% \pkg{fontspec} for various macro programming purposes. +% +% +% \section{Defining new features} \label{sec:newfeatures} +% This package cannot hope to contain every possible font +% feature. Three commands are provided for selecting font features +% that are not provided for out of the box. If you are using +% them a lot, chances are I've left something out, so please let me +% know. +% +% \DescribeMacro{\newAATfeature} +% New \AAT\ features may be created with this command:\par +% {\centering\cmd\newAATfeature\marg{feature}\marg{option}\marg{feature code}\marg{selector code}\par}\noindent +% Use the \XeTeX\ file \path{AAT-info.tex} to obtain the code numbers. For example: +% \begin{aatexample} +% \newAATfeature{Alternate}{HoeflerSwash}{17}{1} +% \fontspec[Alternate=HoeflerSwash]{Hoefler Text Italic} +% This is XeTeX by Jonathan Kew. +% \end{aatexample} +% This command replaces \cmd\newfeaturecode, which is provided +% for backwards compatibility via \texttt{fontspec.cfg}. +% +% \DescribeMacro{\newICUfeature} +% \DescribeMacro{\newopentypefeature} +% New OpenType features may be created with this command:\par +% {\centering\cmd\newICUfeature\marg{feature}\marg{option}\marg{feature tag}\par} +% The synonym \cs{newopentypefeature} is provided for \LuaTeX\ users. +% In the following example, the Moldavian language (see \vref{sec:ot}) must be activated to achieve the effect shown. +% \setexsize\Large +% \begingroup +% \begin{opentypeexample} +% \newICUfeature{Style}{NoLocalForms}{-locl} +% \fontspec[Language=Moldavian]{FPL Neu} +% Ş ş Ţ ţ \\ +% \addfontfeature{Style=NoLocalForms} +% Ş ş Ţ ţ +% \end{opentypeexample} +% \endgroup +% +% \DescribeMacro{\newfontfeature} +% In case the above commands do not accommodate the desired font feature +% (perhaps a new \XeTeX\ feature that \pkg{fontspec} hasn't been updated +% to support), a command is provided to pass arbitrary input into the +% font selection string:\par +% {\centering\cmd{\newfontfeature}\marg{name}\marg{input string}\par} +% +% For example, Zapfino +% contains the feature `Avoid d-collisions'. To access it +% with this package, you could do the following: +% \begin{aatexample} +% \newfontfeature{AvoidD}{Special=Avoid d-collisions} +% \newfontfeature{NoAvoidD}{Special=!Avoid d-collisions} +% \fontspec[AvoidD,Variant=1]{Zapfino} +% sockdolager rubdown \\ +% \fontspec[NoAvoidD,Variant=1]{Zapfino} +% sockdolager rubdown +% \end{aatexample} +% +% The advantage to using the \cmd\newAATfeature\ and \cmd\newICUfeature\ +% commands is that they check if the selected font actually contains the font +% feature. By contrast, \cmd\newfontfeature\ will not give a warning +% for improper input. +% +% \section{Going behind \pkg{fontspec}'s back} +% Expert users may wish not to use \pkg{fontspec}'s feature handling at all, +% while still taking advantage of its \LaTeX\ font selection conveniences. The +% \feat{RawFeature} font feature allows literal \XeTeX\ font feature selection +% when you happen to have the OpenType feature tag memorised. +% \begin{example} +% \fontspec[RawFeature=+smcp]{FPL Neu} +% FPL Neu small caps +% \end{example} +% Multiple features can either be included in a single declaration:\par +% {\centering|[RawFeature=+smcp;+onum]|\par} +% \noindent or with multiple declarations:\par +% {\centering|[RawFeature=+smcp, RawFeature=+onum]|\par} +% +% \section{Renaming existing features \& options} +% \label{sec:aliasfontfeature} +% +% \DescribeMacro{\aliasfontfeature} +% If you don't like the name of a particular font feature, +% it may be aliased to another with the +% \cs{aliasfontfeature}\marg{existing name}\marg{new name} command: +% \begin{aatexample} +% \aliasfontfeature{ItalicFeatures}{IF} +% \fontspec[IF = {Alternate=1}]{Hoefler Text} +% Roman Letters \itshape And Swash +% \end{aatexample} +% +% Spaces in feature (and option names, see below) \emph{are} allowed. (You may have +% noticed this already in the lists of OpenType scripts and languages). +% +% \DescribeMacro{\aliasfontfeatureoption} +% If you wish to change the name of a font feature option, +% it can be aliased to another with the command +% \cs{aliasfontfeatureoption}\marg{font feature}\marg{existing name}\marg{new name}: +% \begin{opentypeexample} +% \aliasfontfeature{VerticalPosition}{Vert Pos} +% \aliasfontfeatureoption{VerticalPosition}{ScientificInferior}{Sci Inf} +% \fontspec[Vert Pos=Sci Inf]{Warnock Pro} +% Scientific Inferior: 12345 +% \end{opentypeexample} +% This example demonstrates an important point: when aliasing the feature +% options, the \emph{original} feature name must be used when declaring +% to which feature the option belongs. +% +% Only feature options that exist as sets of fixed strings may be altered in +% this way. That is, \opt{Proportional} can be aliased to \opt{Prop} in the +% \feat{Letters} feature, but \opt{550099BB} cannot be substituted for \opt{Purple} +% in a \feat{Color} specification. For this type of thing, the \cmd\newfontfeature\ +% command should be used to declare a new, \eg, \feat{PurpleColor} feature: +% \begin{Verbatim} +% \newfontfeature{PurpleColor}{color=550099BB} +% \end{Verbatim} +% +% \section{Programming details} +% +% In some cases, it is useful to know what the \LaTeX\ font family +% of a specific \pkg{fontspec} font is. After a \cmd\fontspec-like +% command, this is stored inside the \cmd\zf@family\ macro. +% Otherwise, \LaTeX's own \cmd\f@family\ macro can be useful here, +% too. +% The raw \TeX\ font that is defined is stored temporarily +% in \cmd{\zf@basefont}. +% +% The following commands in \pkg{expl3} syntax may be used +% for writing codes that interface with fontspec-loaded fonts. +% All of the following conditionals also exist with |T| and |F| +% suffices as well as |TF|. +% +% \begin{macro}{\fontspec_if_fontspec_font:TF} +% Test whether the currently selected font has been loaded by fontspec. +% \end{macro} +% +% +% \begin{macro}{\fontspec_if_aat_feature:nnTF} +% Test whether the currently selected font contains the \AAT\ +% feature (|#1|,|#2|). +% \end{macro} +% +% +% \begin{macro}{\fontspec_if_opentype:TF} +% Test whether the currently selected font is an OpenType font. +% Always true for LuaTeX fonts. +% \end{macro} +% +% \begin{macro}{\fontspec_if_feature:nTF} +% Test whether the currently selected font contains the raw OpenType +% feature |#1|.

E.g.: |\fontspec_if_feature:nTF {latn} {pnum} {True} {False}|. +% Returns false if the font is not loaded by fontspec or is not an OpenType +% font. +% \end{macro} +% +% +% \begin{macro}{\fontspec_if_current_script:nTF} +% Test whether the currently loaded font is using the specified raw +% OpenType script tag |#1|. +% \end{macro} +% +% \begin{macro}{\fontspec_if_current_language:nTF} +% Test whether the currently loaded font is using the specified raw +% OpenType language tag |#1|. +% \end{macro} +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % +% \clearpage +% \part{The patching/improvement of \LaTeXe\ and other packages} +% \label{sec:patching} +% +% Derived originally from xltxtra, this package contains patches to various +% \LaTeX\ components and third-party packages to improve the default +% behaviour. +% +% \section{Inner emphasis} +% \label{sec:emph} +% +% \pkg{fixltx2e}'s method for checking for ``inner'' emphasis is a little fragile in \XeTeX, because +% font slant information might be missing from the font. Therefore, we use \LaTeX's NFSS +% information, which is more likely to be correct. +% +% \section{Unicode footnote symbols} +% By default \LaTeX\ defines symbolic footnote characters in terms of commands +% that don't resolve well; better results can be achieved by using specific unicode characters or proper LICRs with the \pkg{xunicode} package. +% +% This problem has been solved by loading the +% \pkg{fixltx2e} and \pkg{xunicode} packages in \pkg{xltxtra}. +% +% \section{Verbatim} +% \label{sec:verb} +% +% Many verbatim mechanisms assume the existence of a `visible space' character that exists in the \textsc{ascii} space slot of the typewriter font. This character is known in unicode as \unichar{2434}{box open}, which looks like this: `\verb*| |'. +% +% When a unicode typewriter font is used, \LaTeX\ no longer prints visible spaces for the |verbatim*| environment and |\verb*| command. \pkg{xltxtra} fixes this problem by using the correct unicode glyph, and patches the following packages to do the same: +% \pkg{listings}, \pkg{fancyvrb}, \pkg{moreverb}, and \pkg{verbatim}. +% +% In the case that the typewriter font does not contain `\verb*| |', the Latin Modern Mono font is used as a fallback. +% +% \section{Discrectionary hyphenation: \cmd\-} +% \label{sec:hyphen} +% +% \LaTeX\ defines the macro \cmd\-\ to insert discretionary hyphenation points. +% However, it is hard-coded in \LaTeX\ to use the hyphen |-| character. Since \pkg{fontspec} +% makes it easy to change the hyphenation character on a per font basis, it would +% be nice if \cmd\-\ adjusted automatically — and now it does. +% +% \StopEventually{} +% +% \clearpage +% \part{fontspec.sty} +% +% \section{Implementation} +% Herein lie the implementation details of this package. Welcome! +% It was my first. +% +% For some reason, I decided to prefix all the package internal +% command names and variables with |zf|. I don't know why I chose +% those letters, but I guess I just liked the look/feel of them +% together at the time.

Only the `top level' definitions of the +% commands are contained herein; they all use or define macros which +% are defined or used later on in \vref{sec:codeinternal}. +% +% \subsubsection{Font selection} +% \begin{macro}{\fontspec} +% This is the main command of the package that +% selects fonts with various features. It takes two arguments: the +% \MacOSX\ font name and the optional requested features of that +% font.

Given a +% list of font features (|#1|) for a requested font (|#2|, stored +% in \cs{zf@fontname} globally for the +% \cs{zf@make@aat@feature@string} macro), it will define an NFSS +% family for that font and put the family name into \cs{zf@family}. +% +% This macro does its processing inside a group, but it's a bit worthless coz +% there's all sorts of \cmd\global\ action going on. Pity. Anyway, lots of things +% are branched out for the pure reason of splitting +% the code up into logical chunks. Some of it is never even re-used, so it +% all might be a bit obfuscating. (\Eg, \cmd{\fontspec_init:} and \cmd{\fontspec_set_font_type:}.) +% +% First off, initialise some bits and pieces and run the |preparse| feature +% processing. This catches font features such as |Renderer| that can change +% the way subsequent features are processed. All font features that `slip through' +% this stage are saved in the \cmd\zf@font@feat\ macro for future processing. +% \begin{macrocode} +\cs_set:Npn \fontspec_select:nn #1#2 { + \begingroup + \fontspec_init: +% \end{macrocode} +% \cmd{\zf@fontname} is used as the generic name of the font being defined. +% \cmd{\zf@family@long} is the unique identifier of the font with all its +% features. +% \cmd{\zf@up} is the font specifically to be used as the upright font. +% \begin{macrocode} + \edef\zf@fontname{#2} + \let\zf@family@long\zf@fontname + \let\zf@up\zf@fontname +% \end{macrocode} +% Detect if external fonts are to be used, possibly automatically, and +% parse fontspec features for bold/italic fonts and their features. +% \begin{macrocode} + \fontspec_if_detect_external:nT {#2} + { \setkeys[zf]{preparse-external}{ExternalLocation} } + \fontspec_setkeys:xx {preparse-external} {\zf@default@options #1} +% \end{macrocode} +% When \cmd{\zf@fontname} is augmented with a prefix or whatever to create +% the name of the upright font (\cmd{\zf@up}), this latter is the new `general +% font name' to use. +% \begin{macrocode} + \let\zf@fontname\zf@up + \fontspec_setkeys:xx {preparse} {\XKV@rm} + \let\zf@font@feat\XKV@rm +% \end{macrocode} +% \begin{macrocode} + \global\font\zf@basefont="\fontspec_fullname:n {\zf@up}"~at~\f@size pt + \fontspec_set_font_type: + \global\font\zf@basefont="\fontspec_fullname:n {\zf@up}"~at~\f@size pt +% \end{macrocode} +% Now convert the remaining requested features to font definition +% strings. This is performed with \cs{zf@get@feature@requests}, in +% which \cs{setkeys} retrieves the requested font features and +% processes them. To build up the complex family name, it +% concatenates each font feature with the family name of the +% font. So since \cs{setkeys} is run more than once (since different +% font faces may have different feature names), we only want the +% complex family name to be built up once, hence the \cs{zf@firsttime} +% conditionals. +% \begin{macrocode} + \zf@firsttimetrue + \ifzf@icu + \fontspec_setkeys:xxx {feat} {Script} {\l_fontspec_script_name_tl} + \fontspec_setkeys:xxx {feat} {Lang} {\l_fontspec_lang_name_tl} + \fi + \fontspec_get_features:n{\zf@font@feat} + \zf@firsttimefalse +% \end{macrocode} +% Now we have a unique (in fact, too unique!) string that contains +% the family name and every option in abbreviated form. This is used +% with a counter to create a simple NFSS family name for the font we're +% selecting. +% +% The font name is fully expanded, in case it's defined in terms of macros, before having its spaces zapped. +% \begin{macrocode} + \unless\ifcsname zf@UID@\zf@family@long\endcsname + \ifcsname c@zf@famc@#2\endcsname + \expandafter\global\expandafter\advance + \csname c@zf@famc@#2\endcsname\@ne + \else + \expandafter\global\expandafter\newcount + \csname c@zf@famc@#2\endcsname + \fi + \edef\@tempa{#2~} + \cs_gset:cpx{zf@UID@\zf@family@long}{ + \expandafter\zap@space\@tempa\@empty + (\expandafter\the\csname c@zf@famc@#2\endcsname) + } + \fi + \xdef\zf@family{\@nameuse{zf@UID@\zf@family@long}} +% \end{macrocode} +% +% Now that we have the family name, we +% can check to see if the family has already been defined, and if not, +% do so.

Furthermore, it allows very flexible -control over the selection of advanced font features such as number case -and fancy ligatures (and many more!) present in most modern fonts. - -\subsection{Usage} -For basic use, no package options are required: -\begin{Verbatim}[gobble=2] - \usepackage{fontspec}% provides font selecting commands - \usepackage{xunicode}% provides unicode character macros - \usepackage{xltxtra} % provides some fixes/extras -\end{Verbatim} -\name{Ross Moore}'s \pkg{xunicode} package is highly recommended, as it -provides access \LaTeX's various methods for accessing extra -characters and accents (for example, |\%|, |\$|, |\textbullet|, |\"u|, and -so on), plus many more unicode characters. - -The \pkg{xltxtra} package adds a couple of general improvements to \LaTeX\ under -\XeTeX; it also provides the \cmd\XeTeX\ macro to typeset the \XeTeX\ logo. - -\emph{The \pkg{babel} package is not really supported!} Especially Vietnamese, -Greek, and Hebrew at least might not work correctly, as far as I can tell. -There's a better chance with Cyrillic and Latin-based languages, however---\pkg{fontspec} ensures -at least that fonts should load correctly, but hyphenation and other matters -aren't guaranteed. - -The rest of this section documents \pkg{fontspec}'s package options, which are (briefly): -\begin{description}[nolistsep,font=\ttfamily] -\item [cm-default] Don't load the Latin Modern fonts; -\item [no-math] Don't change any maths fonts; -\item [no-config] Don't load \pkg{fontspec.cfg}; and, -\item [quiet] Output \pkg{fontspec} warnings in the log file rather than the console output. -\end{description} - -\subsubsection{Latin Modern defaults} -\pkg{fontspec} defines a new \LaTeX\ font encoding for its purposes to allow -the Latin Modern fonts to be used by default \new{v1.12}. This has three implications: -\begin{enumerate} -\item Unicode fonts are loaded by default; it didn't make sense to have the legacy Computer Modern fonts in the Unicode-enabled \XeTeX. -\item If you don't have the Latin Modern OpenType fonts installed, you might want to consider doing so. -\item \pkg{fontspec} also requires the \pkg{euenc} package\footnote{\url{http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=euenc}} to be installed. -\end{enumerate} -Another package option is provided for controlling this behaviour: |[cm-default]| -will ignore the Latin Modern fonts and go about things as it used to. Use this -option if you don't have the Latin Modern fonts installed or you (Mac-specifically) -want to use the `default \TeX\ font' without using the |xdvipdfmx| driver. - -\subsubsection{Maths `fiddling'} -\new{v1.14} -By default, \pkg{fontspec} adjusts \LaTeX's default maths setup in order to maintain the correct Computer Modern symbols when the roman font changes. However, it will attempt to avoid doing this if another maths font package is loaded (such as \pkg{mathpazo} or my upcoming \pkg{unicode-math} package). - -If you find that it is incorrectly changing the maths font when it should be leaving well enough alone, apply the |[no-math]| package option to manually suppress its maths font. - -\subsubsection{Configuration} -If you wish to customise any part of the \pkg{fontspec} interface (see later -in this manual, \vref{sec:newfeatures} and~\ref{sec:aliasfontfeature}), -this should be done by creating your own \texttt{fontspec.cfg} file, - \note{An example is distributed with the package.} -which will be automatically loaded if it is found by \XeTeX. Either place it -in the same folder as the main document for isolated cases, or in a location that -\XeTeX\ searches by default, \eg, \url{~/Library/texmf/xelatex/}. -The package option |[no-config]| will suppress this behaviour -under all circumstances. -\warn{v1.14}{Used to be \texttt{[noconfig]}, which still works.} - -\subsubsection{Warnings}\label{sec:quiet-warnings} -This package can give many warnings that can be -harmless if you know what you're doing. -Use the |[quiet]| package option to write -these warnings to the transcript (\texttt{.log}) file instead. - -Use the |[silent]| package option to completely suppress these warnings if you don't even want the |.log| file cluttered up. - -\subsection{About this manual} -\warn{v1.6}{An example warning!} -In the unfortunate case that I need to make backwards incompatible changes (you're probably pretty safe these days), such things, and some other comments, are noted in the margin of this document as shown here, with a red star if the -change is relevant to the current release of the package. (New features -are denoted similarly in blue.) - -This document has been typeset with \XeTeX\ using a variety of fonts -to display various features that the package supports. You will not -be able to typeset the documentation if you do not have all of these -fonts, many of which are distributed with \MacOSX\ or are otherwise -commercial. - -Many examples are shown in this manual. These are typeset -side-by-side with their verbatim source code, although various -size-altering commands (\cs{large}, \cs{Huge}, \etc) are omitted for -clarity. Since the package supports font features for both AAT and -OpenType fonts (whose feature sets only overlap to some extent), -examples are distinguished by colour: blue and red, respectively. -Examples whose font type is irrelevant are typeset in green. - -\section{Brief overview} -This manual can get rather in-depth, as there are a lot of font features -to cover. A basic preamble set-up is shown below, to simply select some default -document fonts. See the file \url{fontspec-example.tex} for a more detailed -example. -\begin{Verbatim}[gobble=2] - \usepackage{fontspec} - \defaultfontfeatures{Scale=MatchLowercase} - \setmainfont[Mapping=tex-text]{Baskerville} - \setsansfont[Mapping=tex-text]{Skia} - \setmonofont{Courier} -\end{Verbatim} - -\section{Font selection} - -\DescribeMacro{\fontspec} -\cmd{\fontspec}\oarg{font features}\marg{font name} -is the base command of the package, used -for selecting the specified \meta{font name} in a \LaTeX\ family. -The font features argument -accepts comma separated \meta{font feature}=\meta{option} lists; these will -not be fully described until \vref{sec:features}. - -As our first example, look how easy it is to select the -Hoefler Text typeface with the \pkg{fontspec} package: -\begin{example} - \def\pangram{The five boxing - wizards jump quickly.\\} - \fontspec{Hoefler Text} \pangram - {\itshape \pangram} - {\scshape \pangram} - {\scshape\itshape \pangram} - \bfseries \pangram - {\itshape \pangram} - {\scshape \pangram} - {\itshape\scshape \pangram} -\end{example} -The \pkg{fontspec} package takes care of the necessary font -definitions for those shapes as shown above -\emph{automatically}. Furthermore, it is not necessary to install -the font for \XeTeX\ in any way whatsoever: every font that is -installed in the operating system may be accessed. - -\subsection{Default font families}\label{sec:setxxfont} -\DescribeMacro{\setmainfont} \DescribeMacro{\setsansfont} -\DescribeMacro{\setmonofont} The \cs{setmainfont}, -\note{Or \cmd\setromanfont, a historical name that doesn't make much sense when you're, say, typesetting Greek.} -\cs{setsansfont}, and \cs{setmonofont} commands are used to select -the default font families for the entire document. They take the -same arguments as \cmd{\fontspec}. For example: - \def\pangram{Pack my box with five - dozen liquor jugs.} -\begin{example} - \setmainfont{Baskerville} - \setsansfont[Scale=0.86]{Skia} - \setmonofont[Scale=0.8]{Monaco} - \rmfamily\pangram\par - \sffamily\pangram\par - \ttfamily\pangram -\end{example} -Here, the scales of the fonts have been chosen to equalise their -lowercase letter heights. The \feat{Scale} font feature will be discussed -further in \vref{sec:font-ind-features}, including methods for automatic -scaling. - -\subsection{Font instances for efficiency} -\DescribeMacro{\newfontfamily} -For cases when a specific font with a specific feature set is going -to be re-used many times in a document, it is inefficient to keep -calling \cs{fontspec} for every use. While the command does not -define a new font instance after the first call, the feature options -must still be parsed and processed. - -For this reason, \emph{instances} -of a font may be created with the \cmd\newfontfamily\ command, -\warn{v1.11}{This macro used to be called \cmd\newfontinstance. - Backwards compatibility is preserved via \texttt{fontspec.cfg}.} -as shown in the following example: -\begin{example} - \newfontfamily\notefont{Didot} - \notefont This is a \emph{note}. -\end{example} -This macro should be used to create commands that would be used in -the same way as \cmd\rmfamily, for example. - -\DescribeMacro{\newfontface} -Sometimes only a specific font face is desired, without accompanying italic or bold variants. -This is common when selecting a fancy italic font, say, that has swash features unavailable -in the upright forms. \cmd\newfontface\ is used for this purpose: \new{v1.11} -\begin{example} - \newfontface\fancy - [Contextuals={WordInitial,WordFinal}] - {Hoefler Text Italic} - \fancy where is all the vegemite -\end{example} -\noindent This example is repeated in \vref{sec:contextuals}. - -\subsection{Arbitrary bold/italic/small caps fonts} \label{sec:bfitfonts} -The automatic bold, italic, and bold italic font selections will not be -adequate for the needs of every font: while some fonts mayn't even -have bold or italic shapes, in which case a skilled (or lucky) -designer may be able to chose well-matching accompanying shapes from -a different font altogether, others can have a range of bold and -italic fonts to chose between. The \feat{BoldFont} and -\feat{ItalicFont} features~\warn{v1.6}{These features used to be called - \feat{Bold} and \feat{Italic}, and these shorter names may still be - used if you desire.} are provided for these situations. If only -one of these is used, the bold italic font is requested as the -default from the \emph{new} font. -\begin{example} - \fontspec[BoldFont={Helvetica Neue}] - {Helvetica Neue UltraLight} - Helvetica Neue UltraLight \\ - {\itshape Helvetica Neue UltraLight Italic} \\ - {\bfseries Helvetica Neue } \\ - {\bfseries\itshape Helvetica Neue Italic} \\ -\end{example} -If a bold italic shape is not defined, or you want to specify -\emph{both} custom bold and italic shapes, the \feat{BoldItalicFont} -feature is provided~\warn{v1.6}{\opt{BoldItalic} also works}. - -For those cases that the base font name is repeated, you can -replace it with an asterisk (first character only). For example, -some space can be saved instead of writing `\texttt{Baskerville SemiBold}': -\begin{example} - \fontspec[BoldFont={* SemiBold}]{Baskerville} - Baskerville \textit{Italic} - \bfseries SemiBold \textit{Italic} -\end{example} - -As a matter of fact, this feature can also be used for the upright font too: -\begin{example} - \fontspec[UprightFont={* SemiBold}, - BoldFont={* Bold}]{Baskerville} - Upright \textit{Italic} - \bfseries Bold \textit{Bold Italic} -\end{example} - -Old-fashioned font families used to distribute their small caps -glyphs in separate fonts due to the limitations on the number -of glyphs allowed in the PostScript Type~1 format. Such fonts may be used -by declaring the \feat{SmallCapsFont} of the family you are specifying: -\begin{Verbatim} - \fontspec[ - SmallCapsFont={Minion MM Small Caps & Oldstyle Figures}, - ]{Minion MM Roman} - Roman 123 \\ \textsc{Small caps 456} -\end{Verbatim} - - -\subsection{Math(s) fonts} - -When \cmd\setmainfont, \cmd\setsansfont\ and \cmd\setmonofont\ are -used in the preamble, they also define the fonts to be used in maths -mode inside the \cmd\mathrm-type commands. This only occurs in the -preamble because \LaTeX\ freezes the maths fonts after this stage of -the processing. The \pkg{fontspec} package must also be loaded after -any maths font packages (\eg, \pkg{euler}) to be -successful. (Actually, it is \emph{only} \pkg{euler} that is the -problem.\footnote{Speaking of \pkg{euler}, if you want to use its \texttt{[mathbf]} option, it won't work, and you'll need to put this after \pkg{fontspec} is loaded instead:\ttfamily\cmd\AtBeginDocument\char`\{\cmd\DeclareMathAlphabet\cmd\mathbf\char`\{U\char`\}\char`\{eur\char`\}\char`\{b\char`\}\char`\{n\char`\}}) - -Note that you may find that loading some maths packages won't be as smooth as you expect since \pkg{fontspec} (and \XeTeX\ in general) breaks many of the assumptions of \TeX\ as to where maths characters and accents can be found. Contact me if you have troubles, but I can't guarantee to be able to fix any incompatibilities. The Lucida and Euler maths fonts (the latter loaded with \pkg{euler} rather than \pkg{eulervm}) should be fine; for all others keep an eye out for problems. - -\DescribeMacro{\setmathrm} \DescribeMacro{\setboldmathrm} -\DescribeMacro{\setmathsf} \DescribeMacro{\setmathtt} -However, the default text fonts may not necessarily be the ones you -wish to use when typesetting maths (especially with the use of fancy -ligatures and so on). For this reason, you may optionally use those -commands listed in the margin (in the same way as our other -\cmd\fontspec-like commands) to explicitly state which fonts to use -inside such commands as \cmd\mathrm. Additionally, the -\cmd\setboldmathrm\ command allows you define the font used for -\cmd\mathrm\ when in bold maths mode (which is activated with, among -others, \cmd\boldmath). - -For example, if you were using Optima with the Euler maths font, you -might have this in your preamble: -\begin{Verbatim}[gobble=2] - \usepackage{mathpazo} - \usepackage{fontspec,xunicode} - \setmainfont{Optima} - \setmathrm{Optima} - \setboldmathrm[BoldFont=Optima ExtraBlack]{Optima Bold} -\end{Verbatim} -and this would allow you to typeset something like this: -\begingroup -\setmainfont{Optima Regular} -\begin{example} - $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $ - \\\boldmath - $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $ -\end{example} -\endgroup - -\subsection{External fonts} -\XeTeX\ v0.995 introduced the feature of loading -fonts not installed through the operating system (`external' fonts). This feature is currently -only available through the |xdvipdfmx| driver, which is notably \emph{not} -the default on \MacOSX. - -This feature is handled in \pkg{fontspec} with the font feature \feat{ExternalLocation}. -When this feature is used, the main argument to \cmd\fontspec\ is the \emph{file name} of the -font (in contrast to the usual syntax which requires the font display name) and the argument -to the feature is the (absolute) path to the font. For example: -\begin{verbatim} - \fontspec[ExternalLocation=/Users/will/Fonts/]{CODE2000.TTF} -\end{verbatim} - -If no path is given, then the font will be found in a location normally searched by -\XeTeX, including the current directory. For example, the following declaration -could load either the Latin Modern roman font in the current directory or, say, -in \path{$TEXMF/fonts/opentype/public/lm/}: -\begin{verbatim} - \fontspec[ExternalLocation]{lmroman10-regular} -\end{verbatim} - -Bold and italic fonts cannot be automatically selected when external fonts -are being used; they must be explicitly declared using the methods -described in \vref{sec:bfitfonts}. - -\subsection{Miscellaneous font selecting details} - -By the way, from v1.9, \cmd\fontspec\ and \cmd\addfontfeatures\ -will now ignore following spaces as if it were a `naked' control -sequence; \eg, `|M. \fontspec{...} N|' and `|M. \fontspec{...}N|' -are the same. - -Note that this package redefines the \cs{itshape} and \cs{scshape} -commands in order to allow them to select italic small caps in -conjunction. (This was implicitly shown in the first example, -but it's worth mentioning now, too.) - - -\section{Selecting font features} \label{sec:selectingfeature} - -The commands discussed so far each take an optional argument for -accessing the font features of the requested font. These features -are generally unavailable or harder to access in regular \LaTeX. The -font features and their options are described in -\vref{sec:features}, but before we look at the range of available -font features, it is necessary to discuss how they can be applied. - -\subsection{Default settings} \label{sec:defaults} -\DescribeMacro{\defaultfontfeatures} It is desirable to define -options that are applied to every subsequent font selection command: -a default feature set, so to speak. This may be defined with the -\cmd{\defaultfontfeatures}\marg{font features} command. -New calls of \cs{defaultfontfeatures} overwrite previous ones. -\begin{example} - \fontspec{Didot} - Some `default' Didot 0123456789 \\ - \defaultfontfeatures{Numbers=OldStyle, Colour=888888} - \fontspec{Didot} - Now grey, with old-style figures: 0123456789 -\end{example} - -\subsection{Changing the currently selected features} -\label{sec:addfontfeatures} -\DescribeMacro{\addfontfeatures} -The \cs{addfontfeatures}\marg{font features} -command allows font features to be changed without -knowing what features are currently selected or even what font is -being used. A good example of this could be to add a hook to all -tabular material to use monospaced numbers, as shown in the -following example: -\begin{example} - \fontspec[Numbers=OldStyle]{Skia} - `In 1842, 999 people sailed 97 miles in - 13 boats. In 1923, 111 people sailed 54 - miles in 56 boats.' \bigskip - - {\addfontfeatures{Numbers={Monospaced,Lining}} - \begin{tabular}{@{} cccc @{}} - \toprule Year & People & Miles & Boats \\ - \midrule 1842 & 999 & 75 & 13 \\ - 1923 & 111 & 54 & 56 \\ - \bottomrule - \end{tabular}} -\end{example} -\DescribeMacro{\addfontfeature} -This command may also be executed under the alias \cmd{\addfontfeature}. - -\subsection{Priority of feature selection} -Features defined with \cs{addfontfeatures} override features -specified by \cs{fontspec}, which in turn override features -specified by \cs{defaultfontfeatures}. If in doubt, whenever a -new font is chosen for the first time, an entry is made in the -transcript (\texttt{.log}) file displaying the font name and the -features requested. - -\subsection{Different features for different font shapes} - -It is entirely possible that separate fonts in a family will require -separate options; \eg, Hoefler Text Italic contains various swash -feature options that are completely unavailable in the upright shapes. - -The font features defined at the top level of the optional \cmd\fontspec\ -argument are applied to \emph{all} shapes of the family. -Using \feat{Upright-}, \feat{SmallCaps-}, \feat{Bold-}, -\feat{Italic-}, and \feat{BoldItalicFeatures}, -separate font features may be defined to their respective shapes -\emph{in addition} to, and with precedence over, the `global' font features. -\begin{aatexample} - \fontspec{Hoefler Text} \itshape \scshape - Attention All Martini Drinkers \\ - \addfontfeature{ItalicFeatures={Alternate = 1}} - Attention All Martini Drinkers \\ -\end{aatexample} -Combined with the options for selecting arbitrary \emph{fonts} for -the different shapes, these separate feature options allow the -selection of arbitrary weights in the Skia typeface, for example: -\begin{aatexample} - \fontspec[BoldFont={Skia}, - BoldFeatures={Weight=2}]{Skia} - Skia \\ \bfseries Skia `Bold' -\end{aatexample} - -Note that because most fonts include their small caps glyphs -within the main font, these features are applied \emph{in addition} to -any other shape-specific features as defined above, and hence \feat{SmallCapsFeatures} -can be nested within \feat{ItalicFeatures} and friends. Every combination -of upright, italic, bold and small caps can thus be assigned individual -features, as shown in the following ludicrous example. -\begin{example} - \fontspec[ - UprightFeatures={Colour = 220022, - SmallCapsFeatures = {Colour=115511}}, - ItalicFeatures={Colour = 2244FF, - SmallCapsFeatures = {Colour=112299}}, - BoldFeatures={Colour = FF4422, - SmallCapsFeatures = {Colour=992211}}, - BoldItalicFeatures={Colour = 888844, - SmallCapsFeatures = {Colour=444422}}, - ]{Hoefler Text} - Upright {\scshape Small Caps}\\ - \itshape Italic {\scshape Italic Small Caps}\\ - \upshape\bfseries Bold {\scshape Bold Small Caps}\\ - \itshape Bold Italic {\scshape Bold Italic Small Caps} -\end{example} - -\subsection{Different features for different font sizes} -\label{sec:sizefeature} - -The \feat{SizeFeature} feature \new{v1.13} is a little more complicated -than the previous features discussed. It allows different fonts -and different font features to be selected for a given font -family as the point size varies. - -It takes a comma separated list of braced, comma separated lists of features for each size range. -Each sub-list must contain the \opt{Size} option -to declare the size range, and optionally \opt{Font} to change the -font based on size. Other (regular) fontspec features that are added -are used on top of the font features that would be used anyway. - -\begin{example} - \fontspec[ SizeFeatures={ - {Size={-8}, Font=Apple Chancery, Colour=AA0000}, - {Size={8-14}, Colour=00AA00}, - {Size={14-}, Colour=0000AA}} ]{Skia} - {\scriptsize Small\par} Normal size\par {\Large Large\par} -\end{example} -A less trivial example is shown in the context of optical font sizes -in \vref{sec:opticalsize}. - -To be precise, the \opt{Size} sub-feature accepts arguments in the form shown in \vref{tab:sizing}. -Braces around the size range are optional. For an exact font size (|Size=X|) -font sizes chosen near that size will `snap'. For example, for size definitions -at exactly 11pt and 14pt, if a 12pt font is requested \emph{actually} the -11pt font will be selected. This is a remnant of the past when fonts were designed -in metal (at obviously rigid sizes) and later when bitmap fonts were similarly -designed for fixed sizes. - -If additional features are only required for a single size, the other sizes -must still be specified. As in: -\begin{verbatim} - SizeFeatures={ - {Size=-10,Numbers=Uppercase}, - {Size=10-}} -\end{verbatim} -Otherwise, the font sizes greater than 10 won't be defined! - -\begin{table} -\centering -\begin{tabular}{@{}ll@{}} -\toprule -Input & Font size, $s$ \\ -\midrule - |Size = X-| & $s \geq \texttt{X}$ \\ - |Size = -Y| & $s < \texttt{Y}$ \\ - |Size = X-Y| & $\texttt{X} \leq s < \texttt{Y}$ \\ - |Size = X| & $s = \texttt{X}$ \\ -\bottomrule -\end{tabular} -\caption{Syntax for specifying the size to apply custom font features.}\label{tab:sizing} -\end{table} - - -\section{Font independent options} \label{sec:font-ind-features} - -Features introduced in this section may be used with any font. - -\subsection{Scale} - -In its explicit form, \feat{Scale} takes a single -numeric argument for linearly scaling the font, as demonstrated -in \vref{sec:setxxfont}. -Since version 0.99 of \XeTeX, however, it is now possible to -measure the correct dimensions of the fonts loaded, and hence -calculate values to scale them automatically. - -The \feat{Scale} feature now \warn{v1.9}{As of Dec.\,2005} -also takes the options \opt{MatchLowercase} -and \opt{MatchUppercase}, which will scale the font being selected to match -the current default roman font to either the height of the lowercase or -uppercase letters, respectively. -\begin{example} - \setmainfont{Georgia} - \newfontfamily\lc[Scale=MatchLowercase]{Verdana} - The perfect match {\lc is hard to find.}\\ - \newfontfamily\uc[Scale=MatchUppercase]{Arial} - L O G O \uc F O N T -\end{example} -The amount of scaling used in each instance is reported in the \texttt{.log} file. -Since there is some subjectivity about the exact scaling to be used, these values -should be used to fine-tune the results. - -\subsection{Mapping} - -\feat{Mapping} enables a \XeTeX\ text-mapping scheme. -\begin{example} - \fontspec[Mapping=tex-text]{Cochin} - ``!`A small amount of---text!'' -\end{example} - -\subsection{Colour} - -\feat{Colour} (or \feat{Color}), also shown in \vref{sec:defaults} and -\vref{sec:features}, uses \XeTeX\ font specifications to set the colour of -the text. The colour is defined as a triplet of two-digit Hex RGB -values, with optionally another value for the transparency (where -|00| is completely transparent and |FF| is opaque.) -\begin{example} - \fontsize{48}{48} - \fontspec{Hoefler Text Black} - {\addfontfeature{Color=FF000099}W}\kern-1ex - {\addfontfeature{Color=0000FF99}S}\kern-0.8ex - {\addfontfeature{Color=DDBB2299}P}\kern-0.8ex - {\addfontfeature{Color=00BB3399}R} -\end{example} - -\subsection{Interword space} - -While the space between words can be varied on an individual -basis with the \TeX\ primitive \cmd\spaceskip\ command, it is -more convenient to specify this information when the font is -first defined. - -The space in between words in a paragraph will be chosen automatically -by \XeTeX, and generally will not need to be adjusted. For those -times when the precise details are important, the \feat{WordSpace} -features is -provided, which takes either a single scaling factor to scale the -value that \XeTeX\ has already chosen, or a triplet of comma-separated -values for the nominal value, the stretch, and the shrink of the -interword space, respectively. \Ie, |WordSpace=0.8| is the same as -|WordSpace={0.8,0.8,0.8}|. - -For example, I believe that the Cochin font, as distributed with \MacOSX, -is too widely spaced. Now, this can be rectified, as shown below. -\begingroup -\let\centering\relax -\def\fillertext{Some filler text for our example to take up some - space, and to demonstrate the large default interword space in \textit{Cochin}.} -\begin{example} - \fontspec{Cochin} - \fillertext - \vspace{1em} - - \fontspec[ WordSpace = {0.7 , 0.8 , 0.9} ]{Cochin} - \fillertext -\end{example} -\endgroup -Be careful with the unpredictable things that the AAT font renderer -can do with the text! Unlike \TeX, \MacOSX\ will allow -fonts to letterspace themselves, which can be seen above; OpenType fonts, however, will not -show this tendency, as they do not support this arguably dubious feature. - -\subsection{Post-punctuation space} - -If \cmd\frenchspacing\ is \emph{not} in effect, \TeX\ will allow extra -space after some punctuation in its goal of justifying the lines of text. -Generally, this is considered old-fashioned, but occasionally in small amounts the -effect can be justified, pardon the pun. - -The \feat{PunctuationSpace} feature takes a scaling factor by which to -adjust the nominal value chosen for the font. Note that |PunctuationSpace=0| -is \emph{not} equivalent to \cmd\frenchspacing, although the difference -will only be apparent when a line of text is under-full. -\begingroup -\let\centering\relax -\begin{example} - \nonfrenchspacing - \fontspec{Baskerville} - Letters, Words. Sentences. \par - \fontspec[PunctuationSpace=0.5]{Baskerville} - Letters, Words. Sentences. \par - \fontspec[PunctuationSpace=0]{Baskerville} - Letters, Words. Sentences. -\end{example} -\endgroup - -Also be aware that the above caveat for interword space also applies here, -so after the last line in the above example, the \feat{PunctuationSpace} -for \emph{all} Baskerville instances will be |0|. - -\subsection{Letter spacing} -Letter spacing, or tracking, is the term given to adding (or subtracting) a small amount of horizontal space in between adjacent characters. It is specified with the \feat{LetterSpace}, which takes a numeric argument. - -The letter spacing parameter is a normalised additive factor (not a scaling factor); it is defined as a percentage of the font size. That is, for a 10\,pt font, a letter spacing parameter of `|1.0|' will add 0.1\,pt between each letter. -\begin{example} - \fontspec{Didot} - \addfontfeature{LetterSpace=0.0} - USE TRACKING FOR DISPLAY CAPS TEXT \\ - \addfontfeature{LetterSpace=2.0} - USE TRACKING FOR DISPLAY CAPS TEXT -\end{example} -This functionality \emph{should not be used for lowercase text}, which is spacing correctly to begin with, but it can be very useful, in small amounts, when setting small caps or all caps titles. -Also see the OpenType \opt{Uppercase} -option of the \feat{Letters} feature (\vref*{sec:letters}). - - -\subsection{The hyphenation character} - -The letter used for hyphenation may be chosen with the \feat{HyphenChar} -feature. It takes three types of input, which are chosen according to some -simple rules. If the input is the string \opt{None}, then hyphenation is -suppressed for this font. If the input is a single character, then this -character is used. Finally, if the input is longer than a single character -it must be the UTF-8 slot number of the hyphen character you desire. - -Below, Adobe Garamond Pro's uppercase hyphenation character - \note{I found the character, and its number, in \MacOSX's Character Palette.} -is used to demonstrate a possible use for this feature. -The second example redundantly demonstrates the default behaviour -of using the hyphen as the hyphenation character. -\begingroup -\let\centering\relax -\begin{example} - \def\text - {A MULTITUDE OF OBSTREPEROUSLY HYPHENATED ENTITIES - \par\vspace{1ex}} - \fontspec[HyphenChar=None]{Adobe Garamond Pro} \text - \fontspec[HyphenChar={-}]{Adobe Garamond Pro} \text - \fontspec[HyphenChar="F6BA]{Adobe Garamond Pro} \text -\end{example} -\endgroup -Note that in an actual situation, the \opt{Uppercase} option of the \feat{Letters} feature -would probably supply this for you (see \vref{sec:letters}). - -The \pkg{xltxtra} package redefines \LaTeX's \cmd\-\ macro -such that it adjusts along with the above changes. - - -\subsection{Font transformations} - -In rare situations users may want to mechanically distort the shapes of the glyphs in the current font. Please don't overuse these features; they can be extremely ugly if overused. - -\begin{example} - \fontspec{Charis SIL} \emph{ABCxyz} \quad - \fontspec[FakeSlant=0.2]{Charis SIL} ABCxyz -\end{example} - -\begin{example} - \fontspec{Charis SIL} ABCxyz \quad - \fontspec[FakeStretch=1.2]{Charis SIL} ABCxyz -\end{example} - -\begin{example} - \fontspec{Charis SIL} \textbf{ABCxyz} \quad - \fontspec[FakeBold=1.5]{Charis SIL} ABCxyz -\end{example} - -If values are omitted, their defaults are as shown above. - -\section{Font-dependent features} \label{sec:features} - -This section covers each and every font feature catered for by this -package. Some, in fact, have already be seen in previous -sections. There are too many to list in this introduction, but for a -first taste of what is available, here is an example of the Apple -Chancery typeface: -\setexsize\Large -\begin{aatexample} - \fontspec[ - Colour=CC00CC, - Numbers=OldStyle, - VerticalPosition=Ordinal, - Variant=2]{Apple Chancery} - My 1st example of\\ Apple Chancery -\end{aatexample} -Multiple options may be given to -any feature that accepts non-numerical input, although doing so will -not always work. Some options will override others in generally -obvious ways; \Verb|Numbers={OldStyle,Lining}| doesn't make much -sense because the two options are mutually exclusive, and \XeTeX\ -will simply use the last option that is specified (in this case -using \opt{Lining} over \opt{OldStyle}). - -If a feature or an option is requested that the font does not have, -a warning is given in the console output. As mentioned in \vref{sec:quiet-warnings} -these warnings can be suppressed by selecting the \texttt{[quiet]} package option. - -\subsection{Different font technologies: AAT and ICU}\label{sec:renderer} - -\XeTeX\ supports two rendering technologies for typesetting, selected with -the \feat{Renderer} font feature. The first, \opt{AAT}, is -that provided (only) by \MacOSX\ itself. The second, \opt{ICU}, -is an open source OpenType interpreter. It provides much greater support for -OpenType features, notably contextual arrangement, over \opt{AAT}. - -In general, this feature will not need to be explicitly called: for OpenType -fonts, the \opt{ICU} renderer is used automatically, and for AAT fonts, -\opt{AAT} is chosen by default. Some fonts, however, will contain font tables -for \emph{both} rendering technologies, such as the Hiragino Japanese fonts -distributed with \MacOSX, and in these cases the choice may be required. - -Among some other font features only available through a specific renderer, -\opt{ICU} provides for the \feat{Script} and \feat{Language} features, which allow -different font behaviour for different alphabets and languages; see \vref{sec:ot} -for the description of these features. {\em Because these font features can -change which features are able to be selected for the font instance, they are selected -by \pkg{fontspec} before all others and will automatically and without warning -select the \opt{ICU} renderer.} - - -\subsection{Optical font sizes} \label{sec:opticalsize} - -Optically scaled fonts thicken out as the font size decreases -in order to make the glyph shapes more robust (less prone to losing -detail), which improves legibility. Conversely, at large optical -sizes the serifs and other small details may be more delicately -rendered. - -Optically sized fonts can be seen in either OpenType or Multiple -Master varieties. The differences when dealing with these two are -quite significant. OpenType fonts with optical scaling will exist in -several discrete sizes, and these will be selected by \XeTeX\ -\emph{automatically} determined by the current font size. The -\opt{OpticalSize} option may be used to specify a different optical -size. - -For the OpenType font Warnock Pro, we have three optically sized -variants: caption, subhead, and display. With \opt{OpticalSize} set -to zero, no optical size font substitution is performed: -\begin{opentypeexample} - \fontspec[OpticalSize=0]{Warnock Pro Caption} - Warnock Pro optical sizes \\ - \fontspec[OpticalSize=0]{Warnock Pro} - Warnock Pro optical sizes \\ - \fontspec[OpticalSize=0]{Warnock Pro Subhead} - Warnock Pro optical sizes \\ - \fontspec[OpticalSize=0]{Warnock Pro Display} - Warnock Pro optical sizes -\end{opentypeexample} - -Automatic OpenType optical scaling is shown in the following -example, in which we've scaled down some large text in order to be -able to compare the difference for equivalent font sizes: (this -gives the same output as we saw in the previous example for Warnock -Pro Display) -\begin{opentypeexample} - \fontspec{Warnock Pro} - Automatic optical size \\ - \scalebox{0.4}{\Huge - Automatic optical size} -\end{opentypeexample} - -Multiple Master fonts, on the other hand, are parameterised over -orthogonal font axes, allowing continuous selection along such -features as weight, width, and optical size~(see \vref{sec:mm} for -further details). Whereas an OpenType font will have only a few separate -optical sizes, a Multiple Master font's optical size can be -specified over a continuous range. Unfortunately, this flexibility makes -it harder to create an automatic interface through \LaTeX, and the -optical size for a Multiple Master font must always be specified -explicitly. -\begin{Verbatim} - \fontspec[OpticalSize=11]{Minion MM Roman} - MM optical size test \\ - \fontspec[OpticalSize=47]{Minion MM Roman} - MM optical size test \\ - \fontspec[OpticalSize=71]{Minion MM Roman} - MM optical size test \\ -\end{Verbatim} - -The \feat{SizeFeatures} feature (\vref{sec:sizefeature}) can be -used to specify exactly which optical sizes will be used for ranges -of font size. For example, something like -\begin{verbatim} - \fontspec[ - SizeFeatures={ - {Size=-10, OpticalSize=8 }, - {Size= 10-14, OpticalSize=10}, - {Size= 14-18, OpticalSize=14}, - {Size= 18-, OpticalSize=18}} - ]{Warnock Pro} -\end{verbatim} - -\subsection{Ligatures} - -\feat{Ligatures} refer to the replacement of two separate characters -with a specially drawn glyph for functional or \ae sthetic reasons. -For AAT fonts, you may choose from any combination of \opt{Required}, -\opt{Common}, \opt{Rare} (or \opt{Discretionary}), \opt{Logos}, \opt{Rebus}, -\opt{Diphthong}, \opt{Squared}, \opt{AbbrevSquared}, and \opt{Icelandic}. - -The first three are also supported in OpenType fonts, which may also -use \opt{Historical} and \opt{Contextual}.
