It is possible to have whitespace between a command line option and its
parameter.
tfmtodit creates a font file for use with groff -Tdvi.
tfm_file is the name of the 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 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.
- -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.
