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. |
