tfmtodit - adapt TeX Font Metrics files for groff -Tdvi
tfmtodit [-s] [-g gf-file] [-k skew-char] tfm-file map-file font
tfmtodit --help

tfmtodit --version
tfmtodit creates a font file for use with the dvi output driver
of groff(1). tfm-file is the name of the TeX font metric file
for the font. map-file is a file giving the groff names for
characters in the font; this file should consist of a sequence of
lines of the form
i c1 ... cn
where i is a decimal integer giving the position of the character
in the font, and c1 through cn are are the groff names of the
character. If a character has no groff names but exists in tfm-
file, then it will be put in the groff font file as an unnamed
character. The groff font file is written to font.
The -s option should be given if the font is “special”, meaning
that groff should search it whenever a character is not found in
the current font. In that case, font should be listed as an
argument to the fonts directive in the DESC file; if it is not
special, there is no need to list it, since groff can
automatically mount it when it is first used.
To do a good job of math typesetting, groff requires font metric
information not present in tfm-file. This is because TeX has
separate math italic fonts, whereas groff uses normal italic
fonts for math. The additional information required by groff is
given by the two arguments to the math_fit macro in the Metafont
programs for the Computer Modern fonts. In a text font (a font
for which math_fit is false), Metafont normally ignores these two
arguments. Metafont can be made to put this information into the
GF (“generic font”) files it produces by loading the following
definition after cmbase when creating cm.base.
def ignore_math_fit(expr left_adjustment,right_adjustment) =
special "adjustment";
numspecial left_adjustment*16/designsize;
numspecial right_adjustment*16/designsize;
enddef;
For the EC font family, load the following definition after
exbase—it is probably easiest to patch exbase.mf locally.
def ignore_math_fit(expr left_adjustment,right_adjustment) =
ori_special "adjustment";
ori_numspecial left_adjustment*16/designsize;
ori_numspecial right_adjustment*16/designsize;
enddef;
The only difference from the previous example is the “ori_”
prefix to “special” and “numspecial”.
The GF file created using this modified cm.base or exbase.mf
should be specified with the -g option, which should not be given
for a font for which math_fit is true.
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-g gf-file
Use the gf-file produced by Metafont containing “special”
and numspecial commands to obtain additional font metric
information.
-k skew-char
The skew charcter of this font is at position skew-char.
skew-char should be an integer; it may be given in
decimal, with a leading 0 in octal, or with a leading 0x
in hexadecimal. Any kerns whose second component is skew-
char are ignored.
-s Add the special directive to the generated file font.
