13 !!SYNOPSIS

16 __addftinfo__ [[ __-v__ ] [[ __-__''param
17 value''... ] ''res unitwidth font''
18 !!DESCRIPTION
19
20
21 __addftinfo__ reads a troff font file and adds some
22 additional font-metric information that is used by the groff
23 system. The font file with the information added is written
24 on the standard output. The information added is guessed
25 using some parametric information about the font and
26 assumptions about the traditional troff names for
27 characters. The main information added is the heights and
28 depths of characters. The ''res'' and ''unitwidth''
29 arguments should be the same as the corresponding parameters
30 in the DESC file; ''font'' is the name of the file
31 describing the font; if ''font'' ends with __I__ the
32 font will be assumed to be italic.
33 !!OPTIONS
34
35
36 __-v__ prints the version number.
37
38
39 All other options changes one of the parameters that is used
40 to derive the heights and depths. Like the existing
41 quantities in the font file, each ''value'' is in
42 inches/''res'' for a font whose point size is
43 ''unitwidth''. ''param'' must be one of:
44
45
46 __x-height__
47
48
49 The height of lowercase letters without ascenders such as
50 x.
51
52
53 __fig-height__
54
55
56 The height of figures (digits).
57
58
59 __asc-height__
60
61
62 The height of characters with ascenders, such as b, d or
63 l.
64
65
66 __body-height__
67
68
69 The height of characters such as parentheses.
70
71
72 __cap-height__
73
74
75 The height of uppercase letters such as A.
76
77
78 __comma-depth__
79
80
81 The depth of a comma.
82
83
84 __desc-depth__
85
86
87 The depth of characters with descenders, such as p,q, or
88 y.
89
90
91 __body-depth__
92
93
94 The depth of characters such as parentheses.
95
96
97 __addftinfo__ makes no attempt to use the specified
98 parameters to guess the unspecified parameters. If a
99 parameter is not specified the default will be used. The
100 defaults are chosen to have the reasonable values for a
101 Times font.
