The main +new command provided by \pkg{relsize.sty} is \cmd{\relsize}, which takes one (positive +or negative) number as its argument; the number specifies how many ``steps'' +by which to change the font size, where each step is a scaling factor of~% +1.2, corresponding to the usual difference between the size commands. For +example, if \verb|{\relsize{-2} smaller}| appears in normal sized text, the word +``smaller'' is printed in script size type. If the same command appears in a +\cmd{\Large} section title, then ``smaller'' is printed in normal size. + +\begin{sloppypar} + There are also the commands \cmd{\larger} and \cmd{\smaller}, which normally change the + font size by one step in the obvious direction; \cmd{\larger} is an abbreviation + for \verb|\relsize{+1}|, and \cmd{\smaller} is an abbreviation for \verb|\relsize{-1}|. For + example, \verb+{\large... \larger{WOW!}}+ prints ``WOW'' in \cmd{\Large} type. You can + also specify bigger steps as an optional argument for \cmd{\larger} and \cmd{\smaller}: + \verb+\larger[3]+ is equivalent to \verb+\relsize{3}+; \verb+\smaller[2]+ is \verb+\relsize{-2}+. + Both \cmd{\larger} and \cmd{\smaller} accept negative arguments, but please don't make + things so obscure! If you want to change size by several steps it is + much better to give an increment than to string several \cmd{\larger} commands + together; i.\,e.\@, \verb+\relsize{3}+ or \verb+\larger[3]+, but not \verb+\larger\larger\larger+. +\end{sloppypar} + +All of the \cmd{\relsize}, \cmd{\larger}, and \cmd{\smaller} commands are ``switches'' just +like the regular sizing commands. That is, they change the size for all +following text until the scope is ended by a closing brace. There are +alternate versions called \cmd{\textlarger} and \cmd{\textsmaller} that take some text +as an argument and apply the size change to only that text: +\verb+\textlarger{big}+. + +Using the number of ``magnification steps'' to indicate font size can +be confusing to some people, and limiting in certain uses. There are +commands with syntax \cmd{\text\-scale}\marg{factor}\marg{text} and \cmd{\relscale}\marg{factor} to +select the size based on a scale factor, like \verb+{0.75}+. + +If the size requested is too small or too large, a warning is given, and +the size will only change as far as appropriate, typically \cmd{\tiny} or \cmd{\Huge}. +These limits are controlled by the commands \cmd{\RSsmallest} and \cmd{\RSlargest}, which +get set automatically when \pkg{relsize.sty} is loaded, but you can redefine them +to other length values: \verb+\renewcommand\RSlargest{50pt}+. + +Fine point: The combination \cmd{\relsize}\marg{n}\cmd{\relsize}\texttt{\{}$-\text{\meta{n}}$\texttt{\}} is not guaranteed to +restore the current font size! That is because the increment \meta{n} may be +enough to overflow the range of sizes. Say you are in \cmd{\huge} text already, +and you do \verb+\relsize{4}+. There is nothing bigger than \cmd{\Huge} so that is the +size you get. Then an ensuing \verb+\relsize{-4}+ will take four steps smaller +and change the size to \cmd{\large}. You should use grouping to undo relative +size changes because it is unsafe to counteract one change with an ``equal'' +change in the opposite direction. + +Typically, the font-size commands do not select fonts at regular size +intervals. \cmd{\relsize} (and the others) will select, and execute, the command +for the size closest to the desired size. Then, if the relative difference +from the target size is more than \cmd{\RSpercentTolerance} a further font-size +selection is made. By~default, \cmd{\RSpercentTolerance} is an empty macro, which +causes automatic selection: ``30'' (30\,\%) when the current ``fontshape'' definition +is composed of only discrete sizes, and ``5'' when the fontshape definition +covers ranges of sizes. The higher setting for discrete fonts ensures +only the pre-defined sizes get used. (By~default \LaTeX\ uses Computer +Modern fonts at discrete sizes; you get full coverage of sizes by using +\verb+\usepackage{type1cm}+\@.) For special uses, or when the font shape definitions +are not parsed properly, you can redefine the percent tolerance: +\verb+\renewcommand\RSpercentTolerance{10}+. + +\enlargethispage{-5\baselineskip} + +All of the commands described above are text commands; they cannot be used +in math mode. There are special \cmd{\mathsmaller} and \cmd{\mathlarger} commands +provided, but these do not use the same sizes that the text versions use. +Instead, they step between the usual math ``styles'' which you can explicitly +set using the commands \cmd{\displaystyle}, \cmd{\textstyle}, \cmd{\scriptstyle}, and +\cmd{\scriptscriptstyle} [see Lamport, \LaTeX/Manual (1st~ed, p.\,54); GMS The \LaTeX\ % +Companion, p.\,255]\@. However, the \cmd{\mathlarger} command will also increase the +size beyond regular \cmd{\displaystyle} by selecting a larger regular font size +(using \cmd{\larger})\@. (Yes, this is a kludge, and doesn't work very well, but +it can still be useful.) If you want to use this to create big integral +signs, then you must also load the package \pkg{exscale} so that math symbols +can change size. The sizes selected are: +% +\begin{flushleft} + \small + \begin{tabular}{@{}lll@{}} + \toprule + Current style & \cmd{\mathsmaller} gives & \cmd{\mathlarger} gives \\ + \cmidrule(r){1-1} \cmidrule(lr){2-2} \cmidrule(l){3-3} + \cmd{\displaystyle} & \cmd{\textstyle} (almost same) & \cmd{\displaystyle} in a \cmd{\larger} font \\ + \cmd{\textstyle} & \cmd{\scriptstyle} & \cmd{\displaystyle} (almost same) \\ + \cmd{\scriptstyle} & \cmd{\scriptscriptstyle} & \cmd{\textstyle} \\ + \cmd{\scriptscriptstyle} & \cmd{\scriptscriptstyle} (same) & \cmd{\scriptstyle} \\ + \bottomrule + \end{tabular} +\end{flushleft} +% +For example, try \verb+$\frac{\mathlarger{E}}{E}$+. Note that, for most symbols, +\cmd{\display\-style} and \cmd{\textstyle} are the same size, so \verb+$N \mathlarger{N}$+ +gives two identical $N$'s, but \cmd{\sum} and \cmd{\int} do get bigger in display style: +\verb+$\int\mathlarger{\int}$+, and fractions are treated differently too: +\verb+$\frac{1}{2} \mathlarger{\frac{1}{2}}$+. As you might have guessed, +\cmd{\mathlarger} and \cmd{\mathsmaller} should only be used in math mode. + +These commands will attempt to attach superscripts and subscripts to the +symbol as if the symbol were used alone: \verb+$\mathlarger{\int}_{0}^{\infty}$+ +but math accents and the math spacing behave as if the symbol is enclosed +in braces (which it is). Comparing +% +\begin{flushleft} + \footnotesize +\begin{verbatim} +\[ +| \times | {\times} | \mathlarger{\times} | \mathbin{\mathlarger{\times}} | +\] +\end{verbatim} +\end{flushleft} +% +shows that operators must be explicitly declared to use the right operator +type (\cmd{\mathrel}, \cmd{\mathbin}, \cmd{\mathop}) to get the correct spacing. + +Due to their oddities, the math larger/smaller commands should not be +trusted blindly, and they will not be useful in every instance. + +\end{document} |
