For instance 24%D \type {\tf} is accompanied by \type {\tfa}, \type {\tfb} etc. The 25%D first two characters denote the alternative, while the third 26%D character in these sequences represents the size. The actual size 27%D is saved in a macro. The styles, being roman (\type {\rm}), sans 28%D serif (\type {\ss}) etc. are also available in macros in \type {rm}, 29%D \type {ss} etc. form. 30 31% fontclass % modern dejavu 32% fontbody % ... 10pt 11pt 12pt ... 33% fontstyle % rm ss tt mm hw cg ... 34% fontalternative % tf bf sl it bs bi sc ... 35% fontsize % a b c d ... 36% fontface % 0=normal 1=text 2=script 3=scriptscript 4=x 5=xx (math are temporary) 37 38\def\normalizedbodyfontsize{12pt} 39 40\def\defaultfontbody {\normalizedbodyfontsize} 41\let\defaultfontstyle \empty 42\let\defaultfontalternative \s!tf 43\let\defaultfontsize \empty 44 45\let\globalfontclass \empty 46\let\fontclass \empty 47\let\fontbody \defaultfontbody 48\let\fontstyle \defaultfontstyle 49\let\fontalternative \defaultfontalternative 50\let\fontsize \defaultfontsize 51\let\fontface \!!zerocount 52 53\installmacrostack\fontstyle 54 55% we can use an indirect mapping for fontclasses (map string onto numbers) and indeed this 56% is somewhat more efficient but also makes the code messy ... maybe some day ... 57 58\protect \endinput 59 |
