NAME
     mag - computes fontsizes and magsteps


SYNOPSIS
     mag [-Rdpi] magstep . . .

     mag [-r] [-Rdpi] fontsize . . .


DESCRIPTION
     delim $$ This  tool  calculates  fontsizes  given  magsteps.
     TeXfonts  are  provided as true sized fonts or as magnifica-
     tions.  The fontsize of a true sized font equals the resolu-
     tion of the printer (ex.  300).  The fontsize of a font mag-
     nified $n$ 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.


EXAMPLES
     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`
