13
15 hpftodit creates a font file for use with a Hewlett-Packard Laser‐
16 Jet 4–series (or newer) printer with groff -Tlj4, using data from an HP
17 tagged font metric (TFM) file. tfm_file is the name of the TFM file
18 for the font; Intellifont and TrueType TFM files are supported, but
19 symbol set TFM files are not. map_file is a file giving the groff
20 names for characters in the font; this file should consist of a
21 sequence of lines of the form:
22 m u c1 c2 ... [ # comment ]
24 where m is a decimal integer giving the MSL number of the character, u
26 is a hexadecimal integer giving the Unicode value of the character, and
27 c1, c2, ... are the groff names of the character. The values can be
28 separated by any whitespace; the Unicode value must use uppercase dig‐
29 its A–F, and must be without a leading `0x', `u', or `U+'. Unicode
30 values corresponding to composite glyphs are decomposed; e.g., `u00C0'
31 becomes `u0041_0300'. The name for a glyph without a groff name may be
32 given as uXXXX if the glyph corresponds to a Unicode value, or as an
33 unnamed glyph `---'. If the given Unicode value is in the Private Use
34 Area (0xE000–0xF8FF), the glyph is included as an unnamed glyph. Refer
35 to groff_diff(1) for additional information about unnamed glyphs and
36 how to access them.
37 Blank lines and lines beginning with `#' are ignored. A `#' following
39 one or more groff names begins a comment. Because `#' is a valid groff
40 name, it must appear first in a list of groff names if a comment is
41 included, e.g.,
42 3 0023 # # number sign
44 or
46 3 0023 # sh # number sign
48 rather than
50 3 0023 sh # # number sign
52 which will treat the first `#' as the beginning of the comment.
54 font is the name of the groff font file. The groff font file is writ‐
56 ten to font; if font is specified as `-', the output is written to the
57 standard output.
58 The -s option should be given if the font is special (a font is special
60 if troff should search it whenever a character is not found in the cur‐
61 rent font). If the font is special, it should be listed in the fonts
62 command in the DESC file; if it is not special, there is no need to
63 list it, since troff can automatically mount it when it's first used.
64 If the -i option is used, hpftodit automatically will generate an
66 italic correction, a left italic correction and a subscript correction
67 for each character (the significance of these parameters is explained
68 in groff_font(5)).

71 -a Include characters in the TFM file that are not included in the
72 map file. A glyph with corresponding Unicode value is given the
73 name uXXXX; a glyph without a Unicode value is included as an
74 unnamed glyph `---'. A glyph with a Unicode value in the Pri‐
75 vate Use Area (0xE000–0xF8FF) also is included as an unnamed
76 glyph.
77 This option provides a simple means of adding Unicode-named and
79 unnamed glyphs to a font without including them in the map file,
80 but it affords little control over which glyphs are placed in a
81 regular font and which are placed in a special font. The pres‐
82 ence or absence of the -s option has some effect on which glyphs
83 are included: without the -s option, only the “text” symbol sets
84 are searched for matching glyphs; with the -s option, only the
85 “mathematical” symbol sets are searched. Nonetheless, restrict‐
86 ing the symbol sets searched isn't very selective—many glyphs
87 are placed in both regular and special fonts. Normally, the -a
88 option should be used only as a last resort.
89 -d Dump information about the TFM file to the standard output; this
91 option can be useful for ensuring that a TFM file is a proper
92 match for a font, and that the contents of the TFM file are
93 suitable. The information includes the values of important TFM
94 tags, and a listing (by MSL number for Intellifont TFM files or
95 by Unicode value for TrueType TFM files) of the glyphs included
96 in the TFM file. The unit of measure `DU' for some tags indi‐
97 cates design units; there are 8782 design units per em for
98 Intellifont fonts, and 2048 design units per em for TrueType
99 fonts. Note that the accessibility of a glyph depends on its
100 inclusion in a symbol set; some TFM files list many glyphs but
101 only a few symbol sets.
102 The glyph listing includes the glyph index within the TFM file,
104 the MSL or Unicode value, and the symbol set and character code
105 that will be used to print the glyph. If map_file is given,
106 groff names are given for matching glyphs. If only the glyph
107 index and MSL or Unicode value are given, the glyph does not
108 appear in any supported symbol set and cannot be printed.
109 With the -d option, map_file is optional, and font is ignored if
111 given.
112 -q Suppress warnings about characters in the map file that were not
114 found in the TFM file. Warnings never are given for unnamed
115 glyphs or by glyphs named by their Unicode values. This option
116 is useful when sending the output of hpftodit to the standard
117 output.
118 -v Print the hpftodit version number.
120 -s The font is special. This option adds the special command to
122 the font file, and affects the order in which HP symbol sets are
123 searched for each glyph. Without the -s option, the “text” sets
124 are searched before the “mathematical” symbol sets. With the -s
125 option, the search order is reversed.
126 -in Generate an italic correction for each character so that the
128 character's width plus the character's italic correction is
129 equal to n thousandths of an em plus the amount by which the
130 right edge of the character's bounding is to the right of the
131 character's origin. If this would result in a negative italic
132 correction, use a zero italic correction instead.
133 Also generate a subscript correction equal to the product of the
135 tangent of the slant of the font and four fifths of the x-height
136 of the font. If this would result in a subscript correction
137 greater than the italic correction, use a subscript correction
138 equal to the italic correction instead.
139 Also generate a left italic correction for each character equal
141 to n thousandths of an em plus the amount by which the left edge
142 of the character's bounding box is to the left of the charac‐
143 ter's origin. The left italic correction may be negative.
144 This option normally is needed only with italic or oblique
146 fonts; a value of 50 (0.05 em) usually is a reasonable choice.
