This font, which includes five weights ({\flafamily\fontseries{ul}\selectfont hairline}, {\flafamily\fontseries{l}\selectfont light}, {\flafamily\fontseries{m}\selectfont regular}, {\flafamily\fontseries{b}\selectfont bold} and {\flafamily\fontseries{eb}\selectfont black}), is available from the Google Font Directory~\cite{lato} as TrueType files under the \acronym{OFL} version~1.1. This package provides support for this font in \LaTeX{}. It includes the original TrueType fonts, as well as Type~1 versions, converted for this package using \program{FontForge} for full support with \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/|, \path|source/|, 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} to make \program{Dvips}, \program{dvipdf} and \program{pdf\TeX} aware of the new fonts. \end{enumerate} Note that this package requires the \package{keyval}~\cite{keyval} and \package{slantsc}~\cite{slantsc} (to handle italic/slanted small caps) ones to work. \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 \code{\char`\\flafamily} command to switch the current font to Lato. \subsubsection{Options} \paragraph{Lato as default (sans-serif) font} You can set \LaTeX{} to use Lato as standard font throughout the whole document by passing the \code{default} option to the package: \begin{verbatim} \usepackage[default]{lato} \end{verbatim} To set Lato as default sans-serif only: \begin{verbatim} \usepackage[defaultsans]{lato} \end{verbatim} \paragraph{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 \code{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} \subsection{Encodings} The following encodings are supported: \begin{center} OT1, T1, TS1 (partial) \end{center} To use one or another encoding, give the \LaTeX{} name to the \package{fontenc} package as usual, as in \begin{verbatim} \usepackage[T1]{fontenc} \usepackage{lato} \end{verbatim} Note that, as usual with OT1 encoded fonts, kerning with accented characters is treated poorly, if at all. Note difference in kerning between e.g. \begin{center} \begin{tabular}{ll} \toprule OT1-encoded&{\flafamily To Ta Té}\\ \midrule T1-encoded&{\flafamily\fontencoding{T1}\selectfont To Ta Té}\\ \bottomrule \end{tabular} \end{center} It is therefore advised to always use the Lota fonts in any encoding than OT1 when typing diacritics. \subsection{Available weights and variants} The following table lists the available font series and shapes with their \acronym{NFSS} classification. Parenthesized combinations are provided via substitutions. \begin{center} \begin{tabular}{llll} \toprule family&encoding&series&shape\\ \midrule \multirow{3}{*}{fla}&\multirow{2}{*}{OT1, T1}&\multirow{2}{*}{m, b (bx), eb, l, ul}&n, it (sl)\\ &&&sc, scit (scsl)\\ \cmidrule{2-4} &TS1&m, b (bx), eb, l, ul&n, it (sl)\\ \bottomrule \end{tabular} \end{center} Notice that the small capitals are faked ones (reduced to 80\%). \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{Small dotless ``j''} The Lato font files do not provide any dotless ``j'' glyph. This \LaTeX{} support provides a faked one ({\flafamily\j}), available by typing \code{\char`\\j}, and built using the \command{t1dotlessj} command (from LCDF~Typetools~\cite{lcdf}). \section{License} This package is released under the \LaTeX{} project public license, either version~1.3c or above~\cite{lppl}. Anyway both the TrueType and Type~1 files are delivered under the Open Font License version~1.1~\cite{ofl}. \begin{thebibliography}{9} \bibitem{lato} \url{http://code.google.com/webfonts/family?family=Lato} \bibitem{keyval} \url{http://www.ctan.org/tex-archive/macros/latex/required/graphics/} \bibitem{slantsc} \url{http://www.ctan.org/tex-archive/macros/latex/contrib/slantsc/} \bibitem{lcdf} \url{http://www.lcdf.org/type/} \bibitem{lppl} \url{http://www.latex-project.org/lppl/lppl-1-3c.html} \bibitem{ofl} \url{http://scripts.sil.org/OFL_web} \end{thebibliography} \end{document}
