19 hpftodit creates a font file for use with a Hewlett-Packard
20 LaserJet 4-series (or newer) printer with groff -Tlj4, using data from
21 an HP tagged font metric (TFM) file. tfm-file is the name of the TFM
22 file for the font; Intellifont and TrueType TFM files are supported,
23 but symbol set TFM files are not. map-file is a file giving the groff
24 names for characters in the font; this file should consist of a se‐
25 quence of lines of the form:
26 m u c1 c2 ... [# comment]
27 where m is a decimal integer giving the MSL (Master Symbol List) number
28 of the character, u is a hexadecimal integer giving the Unicode value
29 of the character, and c1, c2, ... are the groff names of the character
30 (see groff_char(7) for a list). The values can be separated by any
31 whitespace; the Unicode value must use uppercase digits A–F, and must
32 be without a leading ‘0x’, ‘u’, or ‘U+’. Unicode values corresponding
33 to composite glyphs are decomposed; e.g., ‘u00C0’ becomes ‘u0041_0300’.
34 The name for a glyph without a groff name may be given as uXXXX if the
35 glyph corresponds to a Unicode value, or as an unnamed glyph ‘---’. If
36 the given Unicode value is in the Private Use Area (0xE000–0xF8FF), the
37 glyph is included as an unnamed glyph. Refer to groff_diff(1) for ad‐
38 ditional information about unnamed glyphs and how to access them.
39 Blank lines and lines beginning with ‘#’ are ignored. A ‘#’ following
41 one or more groff names begins a comment. Because ‘#’ is a valid groff
42 name, it must appear first in a list of groff names if a comment is in‐
43 cluded, e.g.,
44 3 0023 # # number sign
45 or
46 3 0023 # sh # number sign
47 rather than
48 3 0023 sh # # number sign
49 which will treat the first ‘#’ as the beginning of the comment.
50 The groff font file is written to the specified output-font; if this
52 operand is ‘-’, the font file is written to the standard output.
53 The -s option should be given if the font is special (a font is “spe‐
55 cial” if groff should search it whenever a character is not found in
56 the current font). If the font is special, it should be listed in the
57 fonts command in the DESC file; if it is not special, there is no need
58 to list it, since groff can automatically mount it when it's first
59 used.
60 If the -i option is used, hpftodit automatically will generate an
62 italic correction, a left italic correction and a subscript correction
63 for each character (the significance of these parameters is explained
64 in groff_font(5)).
65
67 -a Include characters in the TFM file that are not included in map-
68 file. A glyph with corresponding Unicode value is given the
69 name uXXXX; a glyph without a Unicode value is included as an
70 unnamed glyph ‘---’. A glyph with a Unicode value in the Pri‐
71 vate Use Area (0xE000–0xF8FF) also is included as an unnamed
72 glyph.
73 This option provides a simple means of adding Unicode-named and
75 unnamed glyphs to a font without including them in the map file,
76 but it affords little control over which glyphs are placed in a
77 regular font and which are placed in a special font. The pres‐
78 ence or absence of the -s option has some effect on which glyphs
79 are included: without the -s option, only the “text” symbol sets
80 are searched for matching glyphs; with the -s option, only the
81 “mathematical” symbol sets are searched. Nonetheless, restrict‐
82 ing the symbol sets searched isn't very selective—many glyphs
83 are placed in both regular and special fonts. Normally, the -a
84 option should be used only as a last resort.
85 -d Dump information about the TFM file to the standard output; this
87 option can be useful for ensuring that a TFM file is a proper
88 match for a font, and that the contents of the TFM file are
89 suitable. The information includes the values of important TFM
90 tags, and a listing (by MSL number for Intellifont TFM files or
91 by Unicode value for TrueType TFM files) of the glyphs included
92 in the TFM file. The unit of measure ‘DU’ for some tags indi‐
93 cates design units; there are 8782 design units per em for In‐
94 tellifont fonts, and 2048 design units per em for TrueType
95 fonts. Note that the accessibility of a glyph depends on its
96 inclusion in a symbol set; some TFM files list many glyphs but
97 only a few symbol sets.
98 The glyph listing includes the glyph index within the TFM file,
100 the MSL or Unicode value, and the symbol set and character code
101 that will be used to print the glyph. If map-file is given,
102 groff names are given for matching glyphs. If only the glyph
103 index and MSL or Unicode value are given, the glyph does not ap‐
104 pear in any supported symbol set and cannot be printed.
105 With the -d option, map-file is optional, and output-font is ig‐
107 nored if given.
108 -q Suppress warnings about characters in the map file that were not
110 found in the TFM file. Warnings never are given for unnamed
111 glyphs or by glyphs named by their Unicode values. This option
112 is useful when sending the output of hpftodit to the standard
113 output.
114 -v Print the hpftodit version number and exit.
116 -s The font is special. This option adds the special command to
118 the font file, and affects the order in which HP symbol sets are
119 searched for each glyph. Without the -s option, the “text” sets
120 are searched before the “mathematical” symbol sets. With the -s
121 option, the search order is reversed.
122 -in Generate an italic correction for each character so that the
124 character's width plus the character's italic correction is
125 equal to n thousandths of an em plus the amount by which the
126 right edge of the character's bounding is to the right of the
127 character's origin. If this would result in a negative italic
128 correction, use a zero italic correction instead.
129 Also generate a subscript correction equal to the product of the
131 tangent of the slant of the font and four fifths of the x-height
132 of the font. If this would result in a subscript correction
133 greater than the italic correction, use a subscript correction
134 equal to the italic correction instead.
135 Also generate a left italic correction for each character equal
137 to n thousandths of an em plus the amount by which the left edge
138 of the character's bounding box is to the left of the charac‐
139 ter's origin. The left italic correction may be negative.
140 This option normally is needed only with italic or oblique
142 fonts; a value of 50 (0.05 em) usually is a reasonable choice.
