24 !!DESCRIPTION
25
26
27 __tfmtodit__ creates a font file for use with __groff
28 -Tdvi__. ''tfm_file'' is the name of the TEX font
29 metric file for the font. ''map_file'' is a file giving
30 the groff names for characters in the font; this file should
31 consist of a sequence of lines of the form:
32
33
34 ''n c1 c2'' ...
35
36
37 where ''n'' is a decimal integer giving the position of
38 the character in the font, and ''c1'', ''c2'',... are
39 the groff names of the character. If a character has no
40 groff names but exists in the tfm file, then it will be put
41 in the groff font file as an unnamed character. ''font''
42 is the name of the groff font file. The groff font file is
43 written to ''font''.
44
45
46 The __-s__ option should be given if the font is special
47 (a font is ''special'' if __troff__ should search it
48 whenever a character is not found in the current font.) If
49 the font is special, it should be listed in the __fonts__
50 command in the DESC file; if it is not special, there is no
51 need to list it, since __troff__ can automatically mount
52 it when it's first used.
53
54
55 To do a good job of math typesetting, groff requires font
56 metric information not present in the tfm file. The reason
57 for this is that TEX has separate math italic fonts whereas
58 groff uses normal italic fonts for math. The additional
59 information required by groff is given by the two arguments
60 to the __math_fit__ macro in the Metafont programs for
61 the Computer Modern fonts. In a text font (a font for which
62 __math_fitting__ is false), Metafont normally ignores
63 these two arguments. Metafont can be made to put this
64 information in the gf file by loading the following
65 definition after __cmbase__ when creating
66 __cm.base__:
67
68
69 __def ignore_math_fit(expr left_adjustment,right_adjustment) =
70 special
71 __
72
73
74 The gf file created using this modified __cm.base__
75 should be specified with the __-g__ option. The __-g__
76 option should not be given for a font for which
77 __math_fitting__ is true.
78 !!OPTIONS

84 Print the version number.
85
86
87 __-s__
88
89
90 The font is special. The effect of this option is to add the
91 __special__ command to the font file.
92
93
94 __-k__''n''
95
96
97 The skewchar of this font is at position ''n''. ''n''
98 should be an integer; it may be given in decimal, or with a
99 leading __0__ in octal, or with a leading __0x__ in
100 hexadecimal. The effect of this option is to ignore any
101 kerns whose second component is the specified
102 character.
103
104
105 __-g__''gf_file''
106
107
108 ''gf_file'' is a gf file produced by Metafont containing
109 special and numspecial commands giving additional font
110 metric information.
