Instead, it's common to see ``give me a leading of 15.5\,pt''. And indeed, that's how % \LaTeX's \cmd\fontsize\ command works. % % This package defines the \cmd\leading\marg{length} command, % which sets the leading immediately to the \meta{length} specified. Here's an example:\bigskip % % \noindent % \begin{minipage}[t]{0.49\linewidth} % \leading{11pt}|\leading{11pt}|\\\small %Upon observing him more closely, I perceived that he wore a black silk %apron over his small-clothes; and this was a thing which I thought very %odd. Before I had time to make any remark, however, upon so singular a %circumstance, he interrupted me with a second \emph{``ahem!''} % \end{minipage}\hfill % \begin{minipage}[t]{0.49\linewidth} % \leading{13pt}|\leading{5mm}|\\\small %Upon observing him more closely, I perceived that he wore a black silk %apron over his small-clothes; and this was a thing which I thought very %odd. Before I had time to make any remark, however, upon so singular a %circumstance, he interrupted me with a second \emph{``ahem!''} % \end{minipage} % % \bigskip\noindent % Because \cmd\leading\ uses \cmd\linespread\ internally, the results % of |\leading{15.5pt}| in a 12\,pt document and |\linespread{1.069}| % are identical. But because \cmd\leading\ uses a fixed length, if the % font size of the document changes then its value will need to be % adjusted. This isn't a problem in general, however, because it is common % for different ratios of linespread to be used for different absolute % font sizes anyway. % % \StopEventually{} % \clearpage % \part{The \pkg{\jobname} package} %\iffalse %<*package> %\fi % This is the package. % \begin{macrocode} \ProvidesPackage{leading} [2007/05/06 v0.2 Define leading length] % \end{macrocode} % % \PrintChanges % % \begin{macrocode} \RequirePackage{calc} % \end{macrocode} % % \begin{macro}{\leading} % \darg{Leading (or `baselineskip') length} % This is the whole package.
