It includes the original -OpenType fonts, as well as Type~1 versions, converted for this package -using \program{FontForge}~\cite{fontforge} and -\program{cfftot1}~\cite{cfftot1} for full support with \LaTeX{} and -\program{Dvips}. - -\section{Installation} - -These directions assume that your \TeX{} distribution is -\acronym{TDS}-compliant. - -Once the \path|lato.zip| archive extracted: -\begin{enumerate} -\item Copy \path|doc/|, \path|fonts/|, and \path|tex/| directories to - your \path|texmf/| directory (either your local or global - \path|texmf/| directory). -\item Run \command{mktexlsr} to refresh the file name database and - make \TeX{} aware of the new files. -\item Run \command{updmap --enable Map lato.map}\footnote{Starting - with \TeX Live~2017, use \command{updmap-user} for a local - installation, or \command{updmap-sys} for a global one.} to make - \program{Dvips}, \program{dvipdf} and \program{\TeX} aware of the - new fonts. -\end{enumerate} - -Note that this package requires the following packages to work: -\begin{itemize} -\item \pkg{fontaxes} -\item \pkg{fontspec} (for \hologo{XeLaTeX}/\hologo{LuaLaTeX} support) -\item \pkg{ifluatex} -\item \pkg{ifxetex} -\item \pkg{xkeyval} -\end{itemize} - -\section{Usage} - -\subsection{Calling Lato} - -You can use the Lato font in a \LaTeX{} document by adding the command -\begin{verbatim} -\usepackage{lato} -\end{verbatim} -to the preamble. The package supplies the \cmd{\lato} command to -switch the current font to Lato. - -\subsection{Options} - -\subsubsection{Lato as default (sans-serif) font} - -You can set \LaTeX{} to use Lato as standard font throughout the whole -document by passing the \option{default} option to the package: -\begin{verbatim} -\usepackage[default]{lato} -\end{verbatim} -To set Lato as default sans-serif only, use the \option{defaultsans} -option: -\begin{verbatim} -\usepackage[defaultsans]{lato} -\end{verbatim} - -\subsubsection{OpenType vs. Type~1} - -Depending on the \LaTeX{} rendering engine used, the package will -automatically use: -\begin{itemize} -\item OpenType fonts with \program{\hologo{XeLaTeX}} and - \program{\hologo{LuaLaTeX}} (the \pkg{fontspec} package will be - therefore loaded) -\item Type~1 fonts with all other \LaTeX{} rendering engines - (especially \program{\hologo{pdfLaTeX}}) -\end{itemize} - -The package was written to provide same functionalities whatever the -\TeX{} rendering engine used. Notice that OpenType fonts supply more -typographic features like additional ligatures or stylistic -alternatives. The table~\vref{tab:features} describes all OpenType -features supported by the Lato font family.

This may -be useful to avoid loading the \pkg{fontspec} package. - -\subsubsection{Font scaling} - -The font can be up- and downscale by any factor. This can be used to -make Lato more friendly when used in company with other type faces, -e.g., to adapt the x-height. The package option -\option{scale=\parameter{ratio}} will scale the font according to -\parameter{ratio} (1.0 by default), for example: -\begin{verbatim} -\usepackage[scale=0.95]{lato} -\end{verbatim} - -\subsubsection{Figure versions} - -Lato provides two figure styles (see table~\vref{tab:figures}): - -\begin{itemize} - \item \emph{Lining figures}, designed to match the uppercase letters - in size and color - \item \emph{Old style figures} (also known as text figures), - designed to match lowercase letters -\end{itemize} - -The \pkg{lato} package uses lining figures by default -(\option{lining} option). To select old style figures, use the -\option{oldstyle} option. - -Two figure widths are also available: -\begin{itemize} - \item \emph{Tabular figures}, which each have the same width - \item \emph{Proportional figures}, which vary in width according to - their shape -\end{itemize} - -The \pkg{lato} package uses tabular figures by default -(\option{tabular} option).

This package supplies -macros to individually select figure style and width -locally~\cite{fontaxesdoc}. - -\subsubsection{Encodings} - -The following \LaTeX{} encodings are supported: -\begin{description} -\item[Latin] \acronym{OT1}, \acronym{T1}, \acronym{TS1} (partial) -\item[Cyrillic] \acronym{T2A}, \acronym{T2B}, \acronym{T2C}, \acronym{X2} -\item[Greek] \acronym{LGR} (monotonic and polytonic) -\end{description} -To use one or another encoding, give the \LaTeX{} name to the -\pkg{fontenc} package as usual, as in -\begin{verbatim} -\usepackage[T1]{fontenc} -\usepackage{lato} -\end{verbatim} - -As usual with \acronym{OT1} encoded fonts, kerning with accented -characters is treated poorly, if at all. Note difference in kerning -between these two encoding in table~\vref{tab:kerning}.

However the -\pkg{mdsymbol} package~\cite{mdsymbol} provides mathematical symbol -fonts which fit very well with Lato. In addition, the -\pkg{mathspec}~\cite{mathspec} package (for \hologo{XeLaTeX} or -\hologo{LuaLaTeX} engines) or the -\pkg{mathastext}~\cite{mathastext}\footnote{In particular with the - \code{LGR} option to get Greek letters from the Lato fonts} package -(for other \LaTeX{} engines) can be called to use Lato as math font. - -\section{Known bugs and improvements} - -Please send bug reports and suggestions about the Lato \LaTeX{} -support to \href{mailto:melmorabity@fedoraproject.org}{Mohamed - \name{El~Morabity}}. - -\subsection{Compatibility with previous versions} - -\subsubsection{Legacy \code{fla} family} - -Previous versions of the package used to provide \code{fla} as default -\acronym{NFSS} family for Lato, and the corresponding \cmd{\flafamily} -switch command. Such family and macro are still available in newer -package versions. In particular, the \code{fla} family is now an alias -for the \code{lato-TLF} one. - -\subsubsection{Smallcaps} - -Since the Lato font family doesn't provide yet ``real'' smallcaps, -faked ones were supplied by previous versions of the \pkg{lato} -package (by scaling down uppercase letters), with a very poor -result. Furthermore, there's no convenient way to generate fake -smallcaps with \hologo{XeTeX} or \hologo{LuaTeX} engines and native -OpenType fonts. - -For these reasons, faked small caps are no longer provided, starting -with version~3.0 of the \pkg{lato} package. Anyway \LaTeX{} should -automatically substitute missing smallcap shapes by normal ones. - -\section{License} - -This package is released under the \LaTeX{} project public license, -either version~1.3c or above~\cite{lppl}. Anyway both OpenType and -Type~1 files are delivered under the Open Font License -version~1.1~\cite{ofl}. - -\begin{thebibliography}{9} -\bibitem{dziedzic} \url{http://www.lukaszdziedzic.eu/} -\bibitem{lato} \url{http://www.latofonts.com/} -\bibitem{ofl} \url{http://scripts.sil.org/OFL_web} -\bibitem{fontforge} \url{https://fontforge.github.io/} -\bibitem{cfftot1} \url{https://www.lcdf.org/type/cfftot1.1.html} -\bibitem{fontspecdoc} \url{https://mirrors.ctan.org/macros/xetex/latex/fontspec/fontspec.pdf} -\bibitem{fontaxes} \url{https://www.ctan.org/pkg/fontaxes} -\bibitem{fontaxesdoc} \url{http://mirrors.ctan.org/macros/latex/contrib/fontaxes/fontaxes.pdf} -\bibitem{mdsymbol} \url{https://www.ctan.org/pkg/mdsymbol} -\bibitem{mathspec} \url{https://www.ctan.org/pkg/mathspec} -\bibitem{mathastext} \url{https://www.ctan.org/pkg/mathastext} -\bibitem{lppl} \url{http://www.latex-project.org/lppl/lppl-1-3c.html} -\end{thebibliography} - -\end{document} |
