13 optional.
14
16 afmtodit creates a font file for use with groff, grops, and gropdf.
17 afmtodit is written in perl; you must have perl version 5.004 or newer
18 installed in order to run afmtodit.
19 afm_file is the AFM (Adobe Font Metric) file for the font.
21 map_file is a file that says which groff character names map onto each
23 PostScript character name; this file should contain a sequence of lines
24 of the form
25 ps_char groff_char
27 where ps_char is the PostScript name of the character and groff_char is
29 the groff name of the character (as used in the groff font file). The
30 same ps_char can occur multiple times in the file; each groff_char must
31 occur at most once. Lines starting with # and blank lines are ignored.
32 If the file isn't found in the current directory, it is searched in the
33 `devps/generate' subdirectory of the default font directory.
34 If a PostScript character is not mentioned in map_file, and a generic
36 groff glyph name can't be deduced using the Adobe Glyph List (AGL,
37 built into afmtodit), then afmtodit puts the PostScript character into
38 the groff font file as an unnamed character which can only be accessed
39 by the \N escape sequence in troff. In particular, this is true for
40 glyph variants like `foo.bar'; all glyph names containing one or more
41 periods are mapped to unnamed entities. If option -e is not specified,
42 the encoding defined in the AFM file (i.e., entries with non-negative
43 character codes) is used. Please refer to section `Using Symbols' in
44 the groff info file which describes how groff glyph names are con‐
45 structed.
46 Characters not encoded in the AFM file (i.e., entries which have -1 as
48 the character code) are still available in groff; they get glyph index
49 values greater than 255 (or greater than the biggest character code
50 used in the AFM file in the unlikely case that it is greater than 255)
51 in the groff font file. Glyph indices of unencoded characters don't
52 have a specific order; it is best to access them with glyph names only.
53 The groff font file will be output to a file called font, unless the -o
55 option is used.
56 If there is a downloadable font file for the font, it may be listed in
58 the file /usr/share/groff/1.22.2/font/devps/download; see grops(1).
59 If the -i option is used, afmtodit will automatically generate an
61 italic correction, a left italic correction and a subscript correction
62 for each character (the significance of these parameters is explained
63 in groff_font(5)); these parameters may be specified for individual
64 characters by adding to the afm_file lines of the form:
65 italicCorrection ps_char n
67 leftItalicCorrection ps_char n
68 subscriptCorrection ps_char n
69 where ps_char is the PostScript name of the character, and n is the
71 desired value of the corresponding parameter in thousandths of an em.
72 These parameters are normally needed only for italic (or oblique)
73 fonts.
74
76 -an Use n as the slant parameter in the font file; this is used by
77 groff in the positioning of accents. By default afmtodit uses
78 the negative of the ItalicAngle specified in the afm file; with
79 true italic fonts it is sometimes desirable to use a slant that
80 is less than this. If you find that characters from an italic
81 font have accents placed too far to the right over them, then
82 use the -a option to give the font a smaller slant.
83 -c Include comments in the font file in order to identify the PS
85 font.
86 -ddesc_file
88 The device description file is desc_file rather than the default
89 DESC. If not found in the current directory, the `devps' subdi‐
90 rectory of the default font directory is searched (this is true
91 for both the default device description file and a file given
92 with option -d).
93 -eenc_file
95 The PostScript font should be reencoded to use the encoding
96 described in enc_file. The format of enc_file is described in
97 grops(1). If not found in the current directory, the `devps'
98 subdirectory of the default font directory is searched.
99 -fname The internal name of the groff font is set to name.
101 -in Generate an italic correction for each character so that the
103 character's width plus the character's italic correction is
104 equal to n thousandths of an em plus the amount by which the
105 right edge of the character's bounding box is to the right of
106 the character's origin. If this would result in a negative
107 italic correction, use a zero italic correction instead.
108 Also generate a subscript correction equal to the product of the
110 tangent of the slant of the font and four fifths of the x-height
111 of the font. If this would result in a subscript correction
112 greater than the italic correction, use a subscript correction
113 equal to the italic correction instead.
114 Also generate a left italic correction for each character equal
116 to n thousandths of an em plus the amount by which the left edge
117 of the character's bounding box is to the left of the charac‐
118 ter's origin. The left italic correction may be negative unless
119 option -m is given.
120 This option is normally needed only with italic (or oblique)
122 fonts. The font files distributed with groff were created using
123 an option of -i50 for italic fonts.
124 -oout_file
126 The output file is out_file instead of font.
127 -k Omit any kerning data from the groff font. This should be used
129 only for mono-spaced fonts.
130 -m Prevent negative left italic correction values. Roman font
132 files distributed with groff were created with -i0 -m to improve
133 spacing with eqn(1).
134 -n Don't output a ligatures command for this font. Use this with
136 constant-width fonts.
137 -s The font is special. The effect of this option is to add the
139 special command to the font file.
140 -v Print version.
142 -x Don't use the built-in Adobe Glyph List.
