tfmtodit - adapt TeX Font Metrics files for use with groff
and grodvi

tfmtodit creates a font description file for use with
groff(1)'s dvi output device. tfm-file is the name of
the TeX font metric file for the font. map-file assigns groff
ordinary or special character identifiers to glyph indices in the font; it
should consist of a sequence of lines of the form
i c1 ... cn
where i is a position of the glyph in the font in decimal, and c1
through cn are glyph identifiers in the form used by groff font
descriptions. If a glyph has no groff names but exists in
tfm-file, it is put in the groff font description file as an
unnamed glyph. Output is written in groff_font(5) format to
font-description, a file named for the intended groff font name.
If the font is “special”, meaning that groff
should search it whenever a glyph is not found in the current font, use the
-s option and name font-description in the fonts
directive in the output device's DESC file.
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;
consider patching 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 character 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 font description file.
- /usr/share/groff/1.23.0/font/devdvi/DESC
- describes the dvi output device.
- /usr/share/groff/1.23.0/font/devdvi/F
- describes the font known as F on device dvi.
