S T Y ver 2.0 Mar 15, 1995 + +by Donald Arseneau, asnd@reg.triumf.ca, based on smaller.sty by Bernie +Cosell, cosell@WILMA.BBN.COM, and combined with the version by Matt Swift, +swift@bu.edu. + +It is frequently the case that something should be typeset somewhat larger +or smaller than the surrounding text, whatever that size happens to be. +Specifying such sizing commands explicitly makes it difficult to modify the +font sizes of a document at a later time, and makes it hard to write macros +that work at arbitrary sizes. Relsize.sty defines several commands for LaTeX +to set font sizes relative to the current size. + +To refresh your memory, the font sizing commands in LaTeX are, in order: +\tiny, \scriptsize, \footnotesize, \small, \normalsize, \large, \Large, +\LARGE, \huge, \Huge. The main new command provided is \relsize, which +takes one (positive or negative) number as its argument; the number specifies +how many increments by which to change the font size. For example, if +{\relsize{-2} smaller} appears in normal sized text, the word "smaller" +is printed in footnote sized type. If the same command appears in a \Large +section title, then "smaller" is printed in normal size. + +There are also the commands \larger and \smaller, which normally change the +font size by one step in the obvious direction; \larger is an abbreviation +for \relsize{+1}, and \smaller is an abbreviation for \relsize{-1}. For +example, {\large... \larger{WOW!}} prints "WOW" in \Large type. You can +also specify bigger steps as an optional argument for \larger and \smaller: +\larger[3] is equivalent to \relsize{3}; \smaller[2] is like \relsize{-2}. +Both \larger and \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 \larger commands +together; i.e., \relsize{3} or \larger[3], but not \larger\larger\larger. + +If the size requested is too small or too large, a warning is given, and +the size will only change as far as \tiny or \Huge, as appropriate. + +All of the \relsize, \larger, and \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 \textlarger and \textsmaller that take some text +as an argument and apply the size change to only that text: +\textlarger{big}. + +All of the commands described above are text commands; they cannot be used +in math mode. There are special \mathsmaller and \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 \displaystyle, \textstyle, \scriptstyle, and +\scriptscriptstyle [see Lamport, LaTeX/Manual (1st ed, p.54); GMS The LaTeX +Comapnion, p.255]. However, the \mathlarger command will also increase the +size beyond regular \displaystyle by selecting a larger regular font size +(using \larger). (Yes, this is a kludge, but it is too useful to leave +out.) If you want to use this to create big integral signs, then you must +also load the package "exscale" so that math symbols can change size. +The sizes selected are: + +Current style \mathsmaller gives \mathlarger gives +--------------- ---------------------- ------------------------ +\displaystyle \textstyle (almost same) \displaystyle in a \larger font +\textstyle \scriptstyle \displaystyle (almost same) +\scriptstyle \scriptscriptstyle \textstyle +\scriptscriptstyle \scriptscriptstyle (same) \scriptstyle + +For example, try $\frac{\mathlarger{E}}{E}$. Note that, for most symbols, +\displaystyle and \textstyle are the same size, so $N \mathlarger{N}$ +gives two identical N's, but \sum and \int do get bigger in display style: +$\int\mathlarger{\int}$, and fractions are treated differently too: +$\frac{1}{2} \mathlarger{\frac{1}{2}}$. As you might have guessed, +\mathlarger and \mathsmaller should only be used in math mode. + +Fine point: The combination \relsize{n}\relsize{-n} is not guaranteed to +restore the current font size! That is because the increment "n" may be +enough to overflow the range of sizes. Say you are in \huge text already, +and you do \relsize{4}. There is nothing bigger than \Huge so that is the +size you get. Then an ensuing \relsize{-4} will take four steps smaller +and change the size to \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. + +Donald Arseneau asnd@reg.triumf.ca |
