NAME
tfmtodit - create font files for use with groff -Tdvi
SYNOPSIS
tfmtodit [ -sv ] [ -ggffile ] [ -kskewchar ] tfmfile mapfile font
It is possible to have whitespace between a command line option and its
parameter.
DESCRIPTION
tfmtodit creates a font file for use with groff -Tdvi. tfmfile is the
name of the TeX font metric file for the font. mapfile is a file giv-
ing the groff names for characters in the font; this file should con-
sist 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 cur-
rent 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 infor-
mation 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 mathfit macro in the Metafont programs for the
Computer Modern fonts. In a text font (a font for which mathfitting
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 ignoremathfit(expr leftadjustment,,rightadjustment) ==
special ""adjustment"";;
numspecial leftadjustment**16/designsize;;
numspecial rightadjustment**16/designsize;;
enddef;;
For the EC font family, load the following definition after exbase (it
is probably easiest to patch exbase.mf locally):
def ignoremathfit(expr leftadjustment,,rightadjustment) ==
orispecial ""adjustment"";;
orinumspecial leftadjustment**16/designsize;;
orinumspecial rightadjustment**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 mathfitting is true.
OPTIONS
-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 00 in
octal, or with a leading 00x in hexadecimal. The effect of this
option is to ignore any kerns whose second component is the
specified character.
-ggffile
gffile is a gf file produced by Metafont containing special and
numspecial commands giving additional font metric information.
