15 afmtodit creates a font file for use with groff, grops, and gropdf.
16 afmtodit is written in Perl; you must have Perl version 5.004 or newer
17 installed in order to run afmtodit.
18 afm-file is the AFM (Adobe Font Metric) file for the font.
20 map-file is a file that says which groff character names map onto each
22 PostScript character name; this file should contain a sequence of lines
23 of the form
24 ps-char groff-char
25 where ps-char is the PostScript name of the character and groff-char is
26 the groff name of the character (as used in the groff font file). The
27 same ps-char can occur multiple times in the file; each groff-char must
28 occur at most once. Lines starting with ‘#’ and blank lines are ig‐
29 nored. If the file isn't found in the current directory, it is
30 searched for in the devps/generate subdirectory of the default font di‐
31 rectory.
32 If a PostScript character is not mentioned in map-file, and a generic
34 groff glyph name can't be deduced using the Adobe Glyph List (AGL,
35 built into afmtodit), then afmtodit puts the PostScript character into
36 the groff font file as an unnamed character which can only be accessed
37 by the ‘\N’ escape sequence in a roff document. In particular, this is
38 true for glyph variants named in the form “foo.bar”; all glyph names
39 containing one or more periods are mapped to unnamed entities. If op‐
40 tion -e is not specified, the encoding defined in the AFM file (i.e.,
41 entries with non-negative character codes) is used. Refer to section
42 “Using Symbols” in Groff: The GNU Implementation of troff, the groff
43 Texinfo manual, which describes how groff glyph names are constructed.
44 Characters not encoded in the AFM file (i.e., entries which have ‘-1’
46 as the character code) are still available in groff; they get glyph in‐
47 dex values greater than 255 (or greater than the biggest character code
48 used in the AFM file in the unlikely case that it is greater than 255)
49 in the groff font file. Glyph indices of unencoded characters don't
50 have a specific order; it is best to access them with glyph names only.
51 The groff font file will be output to a file called font, unless the -o
53 option is used.
54 If there is a downloadable font file for the font, it may be listed in
56 the file /usr/share/groff/1.22.4/font/devps/download; see grops(1).
57 If the -i option is used, afmtodit will automatically generate an
59 italic correction, a left italic correction and a subscript correction
60 for each character (the significance of these parameters is explained
61 in groff_font(5)); these parameters may be specified for individual
62 characters by adding to the afm-file lines of the form:
63 italicCorrection ps-char n
64 leftItalicCorrection ps-char n
65 subscriptCorrection ps-char n
66 where ps-char is the PostScript name of the character, and n is the de‐
67 sired value of the corresponding parameter in thousandths of an em.
68 These parameters are normally needed only for italic (or oblique)
69 fonts.
70
72 Whitespace is permitted between a command-line option and its argument.
73 -an Use n as the slant parameter in the font file; this is used by
75 groff in the positioning of accents. By default afmtodit uses
76 the negative of the ItalicAngle specified in the AFM file; with
77 true italic fonts it is sometimes desirable to use a slant that
78 is less than this. If you find that characters from an italic
79 font have accents placed too far to the right over them, then
80 use the -a option to give the font a smaller slant.
81 -c Include comments in the font file in order to identify the Post‐
83 Script font.
84 -ddesc-file
86 The device description file is desc-file rather than the default
87 DESC. If not found in the current directory, the devps subdi‐
88 rectory of the default font directory is searched (this is true
89 for both the default device description file and a file given
90 with option -d).
91 -eenc-file
93 The PostScript font should be reencoded to use the encoding de‐
94 scribed in enc-file. The format of enc-file is described in
95 grops(1). If not found in the current directory, the devps sub‐
96 directory of the default font directory is searched.
97 -fname The internal name of the groff font is set to name.
99 -in Generate an italic correction for each character so that the
101 character's width plus the character's italic correction is
102 equal to n thousandths of an em plus the amount by which the
103 right edge of the character's bounding box is to the right of
104 the character's origin. If this would result in a negative
105 italic correction, use a zero italic correction instead.
106 Also generate a subscript correction equal to the product of the
108 tangent of the slant of the font and four fifths of the x-height
109 of the font. If this would result in a subscript correction
110 greater than the italic correction, use a subscript correction
111 equal to the italic correction instead.
112 Also generate a left italic correction for each character equal
114 to n thousandths of an em plus the amount by which the left edge
115 of the character's bounding box is to the left of the charac‐
116 ter's origin. The left italic correction may be negative unless
117 option -m is given.
118 This option is normally needed only with italic (or oblique)
120 fonts. The font files distributed with groff were created using
121 an option of -i50 for italic fonts.
122 -ooutput-file
124 The output file is output-file instead of font.
125 -k Omit any kerning data from the groff font; use only for mono‐
127 spaced (constant-width) fonts.
128 -m Prevent negative left italic correction values. Roman font
130 files distributed with groff were created with -i0 -m to improve
131 spacing with eqn(1).
132 -n Don't output a ligatures command for this font; use with mono‐
134 spaced (constant-width) fonts.
135 -s The font is special. The effect of this option is to add the
137 special command to the font file.
138 -v Print version and exit.
140 -x Don't use the built-in Adobe Glyph List.
