11
13 tfmtodit creates a font file for use with groff -Tdvi. tfm_file is the
14 name of the TeX font metric file for the font. map_file is a file giv‐
15 ing the groff names for characters in the font; this file should con‐
16 sist of a sequence of lines of the form:
17
18 n c1 c2 ...
19
20 where n is a decimal integer giving the position of the character in
21 the font, and c1, c2,... are the groff names of the character. If a
22 character has no groff names but exists in the tfm file, then it will
23 be put in the groff font file as an unnamed character. font is the
24 name of the groff font file. The groff font file is written to font.
25
26 The -s option should be given if the font is special (a font is special
27 if troff should search it whenever a character is not found in the cur‐
28 rent font.) If the font is special, it should be listed in the fonts
29 command in the DESC file; if it is not special, there is no need to
30 list it, since troff can automatically mount it when it's first used.
31
32 To do a good job of math typesetting, groff requires font metric infor‐
33 mation not present in the tfm file. The reason for this is that TeX
34 has separate math italic fonts whereas groff uses normal italic fonts
35 for math. The additional information required by groff is given by the
36 two arguments to the math_fit macro in the Metafont programs for the
37 Computer Modern fonts. In a text font (a font for which math_fitting
38 is false), Metafont normally ignores these two arguments. Metafont can
39 be made to put this information in the gf file by loading the following
40 definition after cmbase when creating cm.base:
41
42 def ignore_math_fit(expr left_adjustment,right_adjustment) =
43 special "adjustment";
44 numspecial left_adjustment*16/designsize;
45 numspecial right_adjustment*16/designsize;
46 enddef;
47
48 For the EC font family, load the following definition after exbase (it
49 is probably easiest to patch exbase.mf locally):
50
51 def ignore_math_fit(expr left_adjustment,right_adjustment) =
52 ori_special "adjustment";
53 ori_numspecial left_adjustment*16/designsize;
54 ori_numspecial right_adjustment*16/designsize;
55 enddef;
56
57 The gf file created using this modified cm.base or exbase should be
58 specified with the -g option. The -g option should not be given for a
59 font for which math_fitting is true.
60
62 It is possible to have whitespace between a command line option and its
63 parameter.
64
65 -v Print the version number.
66
67 -s The font is special. The effect of this option is to add the
68 special command to the font file.
69
70 -kn The skewchar of this font is at position n. n should be an
71 integer; it may be given in decimal, or with a leading 0 in
72 octal, or with a leading 0x in hexadecimal. The effect of this
73 option is to ignore any kerns whose second component is the
74 specified character.
75
76 -ggf_file
77 gf_file is a gf file produced by Metafont containing special and
78 numspecial commands giving additional font metric information.
