description
tfmtodit
creates a font file for use with groff -Tdvi.
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:
n c1 c2
...
where n
is a decimal integer giving the position of the character in
the font, and c1, c2,... are the groff names
of the character. If a character has no groff names but
exists in the tfm file, then it will be put in the groff
font file as an unnamed character. font is the name
of the groff font file. The groff font file is written to
font.
The
-s option should be given if the font is
special (a font is special if troff should
search it whenever a character is not found in the current
font.) If the font is special, it should be listed in the
fonts command in the DESC file; if it is not special,
there is no need to list it, since troff can
automatically mount it when it’s first used.
To do a good
job of math typesetting, groff requires font metric
information not present in the tfm file. The reason for this
is that 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_fitting is false), Metafont normally ignores
these two arguments. Metafont can be made to put this
information in the gf file 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 gf file
created using this modified cm.base or exbase
should be specified with the -g option. The
-g option should not be given for a font for
which math_fitting is true.
options
It is possible
to have whitespace between a command line option and its
parameter.
-v
Print the version number.
-s
The font is special. The effect of this option is to add
the special command to the font file.
-kn
The skewchar of this font is at position n.
n should be an integer; it may be given in decimal,
or with a leading 0 in octal, or with a leading
0x in hexadecimal. The effect of this option is to
ignore any kerns whose second component is the specified
character.
-ggf_file
gf_file is a gf file
produced by Metafont containing special and numspecial
commands giving additional font metric information.
