Man1 - mag.1

mag - computes TeX fontsizes and magsteps

mag [-*R*/dpi] magstep . . ./

mag [-*r*/] [-*R*/dpi] fontsize . . .

delim $$

This tool calculates fontsizes given magsteps. TeXfonts are provided as true sized fonts or as magnifications. The fontsize of a true sized font equals the resolution of the printer (ex. 300). The fontsize of a font magnified \(n\) magsteps equals:

1.2 sup{n} times 300 delim off

rounded to its nearest integer value. Fontnames for TeX fonts normally consists of the name (cmr), pointsize (10), type (pk) and fontsize (/360), for example: cmr10.360pk. /

The result of /mag -R240 -2 0 0.5 1 will be: /

  167 240 263 288 

The inverse function is computed with the -r option. The result of mag -r -R240 167 240 263 288 will be the fontsteps:

  -2 0 0.5 1

The UNIX shells allow command substitution. One can write:

  mag -r -R240 `mag -R240 -2 0 0.5 1`
