This experience made -me familiar with such units, so I later decided to make METAFONT produce -proofmode output at the same scale. - -The basic fonts cmr5--cmr17 scale proportionately in most vertical -dimensions (e.g., the x_height in 5pt is half that in 10pt), but -horizontally the smaller fonts are more extended and have relatively -heavier weight (especially in hairlines). - -The slanted fonts cmsl8--cmsl12 are identical to their unslanted -counterparts except that they have slant=1/6. - -Font cmdunh10 is the same as cmr10 except that body_height, asc_height, -cap_height, and fig_height have been drastically increased. - -The bold fonts cmbx5--cmbx12 have similar vertical dimensions to the ordinary -roman (except that the x_height is a bit taller and bar_height is lower); -they use bolder pen strokes, of course, and they are rather more extended. -Font cmb10 is like cmbx10 except not extended (i.e., 1em=10pt in cmb10, -but 1em=11.5pt in cmbx10); it also has slightly shorter cap serifs. Font -cmbxsl10 is like cmbx10 but slanted. - -The typewriter fonts cmtt8--cmtt12 have the same x_heights as their -roman counterparts, but they have shorter ascenders and longer descenders. -Their math_axis is based on ascenders only. The stroke weights are -almost all identical to the corresponding roman stem weight. -Font cmsltt10 is a slanted version of cmtt10; cmvtt10 is non-monospaced. - -The sans serif fonts cmss8--cmss17 are analogous to cmr8--cmr17; they have -slanted counterparts with slant of 12 degrees. A few other isolated sans -serif fonts appear in the standard set, as demonstrations of how other -varieties could be made: There's a demibold condensed version, cmssdc10, -and a bold extended version, cmssbx10. (The title pages in The TeXbook use -cmssdc10 at 40pt and a magnified version of cmssbx10 called cminch; to -save font storage space, cminch is restricted to digits and uppercase -letters only.) Finally, there's a pair of fonts called cmssq8 and cmssqi8; -these are in a rather different style (extended, with short ascenders -and descenders), used for the end-of-chapter quotations in The TeXbook. - -The font cmfib8 is another `demonstration' of parameters; it's a serifed -font whose proportions are based on Fibonacci numbers. Also, the font -cmff10 is a weird concoction of little use except for testing. - -The text italic fonts cmti7--cmti12 have parameters like their roman -cousins, except that they are more condensed and slightly lighter. -The math italic fonts cmmi5--cmmi12 are not condensed and not -quite as light. - -Four special italic fonts are provided as demonstrations of further -possibilities: cmbxti10 is a bold extended text italic; cmmib10 is -a bold math italic; cmit10 is an italic typewriter font; cmu10 is -an unslanted italic with the same stem weights as cmr10. - -The math symbol fonts, cmsy5--cmsy10, have the same parameters -as the corresponding math italic; these fonts also have special -parameters of their own. There's a bold math symbols font for -demonstration purposes: cmbsy10. - -The math extension font, cmex10, has the parameters of cmr10. - -The extended ASCII font, cmtex10, has the parameters of cmtt10, except -that the slant is positive (for a few characters that will be slanted). - -And finally there are two caps-and-small-caps fonts, cmcsc10 (to match cmr10) -and cmtcsc10 (to match cmtt10). These fonts are unusual in having two -sets of parameters, one for the upper uppercase and one for the lower uppercase. |
