Note that much of the functionality addressed here is provided in abstracted form in various \LaTeX\ packages and Con\TeX{}t modules. - -\part{\XeTeX\ specifics} - -\section{The {\ttfamily\char`\\font} command} -The |\font| command has seen significant addition in \XeTeX\ to facilitate rich font feature selection. Under \TeX, fonts were selected like so: |\font\1="|\xarg{font name}|"| with various options appended such as `|at 10pt|' or `|scaled 1.2|'. This syntax has been extended in \XeTeX\ by passing additions options through the \xarg{font name}. - -This syntax looks something like\par -{\centering|\font\1="|\xarg{font name}\xarg{font options}|:|\xarg{font features}|"| \xarg{\TeX\ font features}\par}\noindent -The \xarg{font name} is the actual name of the font; e.g., `|Charis SIL|'. - -When using the |xdvipdfmx| driver (not yet the default in Mac~OS~X), it is possible to use fonts -that aren't installed in the operating system by surrounding their name with square brackets. The current directory and the |texmf| trees are searched for files named in this way, or the path may be embedded in the -font declaration. \Eg, -\begin{quote}\small -|\font\1="[fp9r8a]"| \hfill \emph{Selects `FPL Neu' in the current directory} -|\font\1="[/myfonts/fp9r8a]"| \hfill \emph{Selects `FPL Neu' somewhere else} -|\font\1="[lmroman10-regular]"| \hfill \emph{Selects a Latin Modern font in the \emph{TDS}} -\end{quote} - -The other arguments are optional and described subsequently. - -\subsection{Font options} - -\xarg{Font options} may be an concatenation of the following: -\begin{optdesc} -\item[/B] Use the bold version of the selected font. -\item[/I] Use the italic version of the selected font. -\item[/BI] Use the bold italic version of the selected font. -\item[/IB] Same as \texttt{/BI}. -\item[/S=$x$] Use the version of the selected font corresponding to the optical size $x$\,pt. -\item[/AAT] Explicitly use the ATSUI renderer (Mac OS X only). -\item[/ICU] Explicitly use the ICU OpenType renderer (only useful on Mac OS X). -\end{optdesc} -Font options aren't applicable when the font is selected locally (\ie, with square brackets). - -\subsection{Font features} - -The \xarg{font features} is a comma or semi-colon separated list activating or deactivating various AAT or OpenType font features, which will vary by font. -The \XeTeX\ documentation files \path{aat-info.tex} and \path{opentype-info.tex} provide per-font lists of supported features. - -\subsubsection{Arbitrary AAT or OpenType features.} -OpenType font features are chosen with standard tags, registered with Adobe or Microsoft: see -\hlink{http://www.microsoft.com/typography/otspec/featuretags.htm}{this link}. - -\begin{example} -\font\warnock="Warnock Pro/I/S=5:+smcp" at 12pt -\warnock This is the OpenType font Warnock Pro in italic - with small caps at a small optical size. -\end{example} - -AAT font features are specified by strings within each font. Therefore, even equivalent features between different fonts can have different names. -\begin{example} -\font\hoefler="Hoefler Text/B:Letter Case=Small Caps" at 12pt -\hoefler This is the AAT font Hoefler Text in bold with small caps. -\end{example} - -Some font features may be applied for any font. These are -\begin{optdesc} -\item[mapping=\textsl{<font map>}] Uses the specified font mapping for this font. -\item[color={\slshape RRGGBB}{[{\slshape TT}]}] Triple pair of hex values to specify the colour in RGB space, with an optional value for the transparency. -\item[letterspace=$x$] Adds $x/S$ space between letters in words, where $S$ is the font size. -\end{optdesc} - -\subsubsection{OpenType script and language support} -OpenType font features can vary by script (`alphabet') and by language. -\begin{optdesc} -\item[script=\textsl{<script tag>}] See \hlink{http://www.microsoft.com/typography/otspec/scripttags.htm}{this link}. -\item[language=\textsl{<lang tag>}] See \hlink{http://www.microsoft.com/typography/otspec/languagetags.htm}{this link}. -\end{optdesc} - -\subsubsection{Multiple Master and Variable Axes AAT font support} - -\begin{optdesc} -\item[weight=$x$] Selects the normalised font weight, $x$. -\item[width=$x$] Selects the normalised font width, $x$. -\item[optical size=$x$] Selects the optical size, $x$. Note the difference between the \texttt{/S} font option, which selects discrete fonts. -\end{optdesc} - -\section{\XeTeX's {\ttfamily\char`\\special}s} - -\textit{To be addressed. Hopefully not by me.} - -\part{New commands} - -\section{Font primitives} - -\cmd|\XeTeXuseglyphmetrics| -\xarg{Integer} -\desc{Boolean to specify if the height and depth of characters are taken into account ($\ge\mathtt1$). Otherwise ($<\mathtt1$), a single height and depth for the entire alphabet is used. When activated, by default, gives better output but is slower.} -\endcmd - -\begin{example} -\XeTeXuseglyphmetrics=0 \fbox{a}\fbox{A}\fbox{j}\fbox{J} vs. -\XeTeXuseglyphmetrics=1 \fbox{a}\fbox{A}\fbox{j}\fbox{J} -\end{example} - -\cmd|\XeTeXglyph| -\xarg{Glyph slot} -\desc{Inserts the glyph in \xarg{slot} of the current font. \strong{Font specific}, so will give different output for different fonts.} -\endcmd - -\cmd|\XeTeXglyphindex| -\xarg{Glyph name} -\desc{Returns the \xarg{glyph slot} corresponding to the (possibly font specific) \xarg{glyph name} in the currently selected font.
