Once you +% have included "isf" as a style option, you can use the \isf command to +% select the italic san serif style, just as you would select the usual +% italic style with \it, EXCEPT: +% +% The various fonts defined here are all "loaded on demand". As +% discussed in the LaTeX book, Section C.14.4, a loaded on demand +% font is subject to two restrictions when used in math mode: +% +% - The font must be used OUTSIDE of math mode before it is used +% INSIDE of math mode. The \load command can be used to get +% around this restriction. +% +% - Only a single font size is available within math mode - the +% display, text, script and scriptscriptfonts will all be the +% same. This can be avoided ONLY by changing the definitions +% given here to pre-load the appropriate fonts; see LFONTS.TEX +% for further information. (Alternatively, \@getfont could be +% made more clever.) Note that pre-loading the fonts could cause +% you to fill font space with fonts you never really use. +% +% In order to allow other style files that need access to \isf to input this +% file safely, it is designed so that an attempt to input it a second time - +% or, more exactly, when command "\isf" is already defined - is ignored. +% +% This file can be adapted easily to define other font type styles. The real +% limit is likely to come from the requirement that each style so defined must +% be given a unique family number - TeX only supports 16 families and LaTeX +% as usually configured already uses 10. The right way to avoid this problem +% is to modify \@getfont so that it ignores a family number of -1. Fonts +% so specified would not be usable in math mode, but that's no big deal; you +% don't WANT to use tons of non-math fonts in math mode anyway. +% +% As currently written, this file assumes that you have boldface san serif +% fonts available at the following point sizes: +% +% lcmssi8 +% lcmssi8 at 9pt +% cmssi10 +% cmssi10 at 11pt +% cmssi10 at 12pt +% cmssi10 at 17pt +% cmssi10 at 20pt +% cmssi10 at 25pt +% +% All but the last of these should be commonly available. I'm not sure about +% the last one; LFONTS.TEX does not assume the availability of ANY 25 pt fonts +% other than Roman. If necessary, change the definition of \isfxxv@ to +% \@subfont\isf\it. (Alternatively, if you have italic sans serif fonts +% at sizes smaller than 8pt, you might want to change the definitions of +% \isfv@, \isfvi@, and \isfvii@.) +% +% Technical note: It is possible to do without the \isf<size>@ macros by +% including their contents, with a whole bunch of \@prtct's, within the +% \@addfontinfo definitions. This is a pain to do, and probably doesn't end +% up saving any space anyway. This way costs you a bunch of extra macros, +% but it's a LOT easier to understand! +% +% Written by George D.
