13 afmtodit creates a font file for use with groff and grops. afmtodit is
14 written in perl; you must have perl version 3 or newer installed in
15 order to run afmtodit. afm_file is the AFM (Adobe Font Metric) file
16 for the font. map_file is a file that says which groff character names
17 map onto each PostScript character name; this file should contain a
18 sequence of lines of the form
19 ps_char groff_char
21 where ps_char is the PostScript name of the character and groff_char is
23 the groff name of the character (as used in the groff font file). The
24 same ps_char can occur multiple times in the file; each groff_char must
25 occur at most once. Lines starting with # and blank lines are ignored.
26 font is the groff name of the font. If a PostScript character is in
27 the encoding to be used for the font but is not mentioned in map_file
28 then afmtodit will put it in the groff font file as an unnamed charac‐
29 ter, which can be accessed by the \N escape sequence in troff. The
30 groff font file will be output to a file called font.
31 If there is a downloadable font file for the font, it may be listed in
33 the file /usr/share/groff/1.18.1.4/font/devps/download; see grops(1).
34 If the -i option is used, afmtodit will automatically generate an
36 italic correction, a left italic correction and a subscript correction
37 for each character (the significance of these parameters is explained
38 in groff_font(5)); these parameters may be specified for individual
39 characters by adding to the afm_file lines of the form:
40 italicCorrection ps_char n
42 leftItalicCorrection ps_char n
43 subscriptCorrection ps_char n
44 where ps_char is the PostScript name of the character, and n is the
46 desired value of the corresponding parameter in thousandths of an em.
47 These parameters are normally needed only for italic (or oblique)
48 fonts.
49
51 -v Print version.
52 -n Don't output a ligatures command for this font. Use this with
54 constant-width fonts.
55 -s The font is special. The effect of this option is to add the
57 special command to the font file.
58 -ddesc_file
60 The device description file is desc_file rather than the default
61 DESC.
62 -eenc_file
64 The PostScript font should be reencoded to use the encoding
65 described in enc_file. The format of enc_file is described in
66 grops(1).
67 -an Use n as the slant parameter in the font file; this is used by
69 groff in the positioning of accents. By default afmtodit uses
70 the negative of the ItalicAngle specified in the afm file; with
71 true italic fonts it is sometimes desirable to use a slant that
72 is less than this. If you find that characters from an italic
73 font have accents placed too far to the right over them, then
74 use the -a option to give the font a smaller slant.
75 -in Generate an italic correction for each character so that the
77 character's width plus the character's italic correction is
78 equal to n thousandths of an em plus the amount by which the
79 right edge of the character's bounding is to the right of the
80 character's origin. If this would result in a negative italic
81 correction, use a zero italic correction instead.
82 Also generate a subscript correction equal to the product of the
84 tangent of the slant of the font and four fifths of the x-height
85 of the font. If this would result in a subscript correction
86 greater than the italic correction, use a subscript correction
87 equal to the italic correction instead.
88 Also generate a left italic correction for each character equal
90 to n thousandths of an em plus the amount by which the left edge
91 of the character's bounding box is to the left of the charac‐
92 ter's origin. The left italic correction may be negative.
93 This option is normally needed only with italic (or oblique)
95 fonts. The font files distributed with groff were created using
96 an option of -i50 for italic fonts.
