HPFTODIT(1) General Commands Manual HPFTODIT(1)
hpftodit - create font description files for use with groff -Tlj4
hpftodit [-aqsv] [-i n] tfm-file map-file output-font
hpftodit -d tfm-file [map-file]
hpftodit creates a font file for use with a Hewlett-Packard
LaserJet 4-series (or newer) printer with groff -Tlj4, using data
from an HP tagged font metric (TFM) file. tfm-file is the name of
the TFM file for the font; Intellifont and TrueType TFM files are
supported, but symbol set TFM files are not. map-file is a file
giving the groff names for characters in the font; this file should
consist of a sequence of lines of the form:
m u c1 c2 ... [# comment]
where m is a decimal integer giving the MSL (Master Symbol List) num‐
ber of the character, u is a hexadecimal integer giving the Unicode
value of the character, and c1, c2, ... are the groff names of the
character (see groff_char(7) for a list). The values can be sepa‐
rated by any whitespace; the Unicode value must use uppercase digits
A–F, and must be without a leading ‘0x’, ‘u’, or ‘U+’. Unicode val‐
ues corresponding to composite glyphs are decomposed; e.g., ‘u00C0’
becomes ‘u0041_0300’. The name for a glyph without a groff name may
be given as uXXXX if the glyph corresponds to a Unicode value, or as
an unnamed glyph ‘---’. If the given Unicode value is in the Private
Use Area (0xE000–0xF8FF), the glyph is included as an unnamed glyph.
Refer to groff_diff(1) for additional information about unnamed
glyphs and how to access them.
Blank lines and lines beginning with ‘#’ are ignored. A ‘#’ follow‐
ing one or more groff names begins a comment. Because ‘#’ is a valid
groff name, it must appear first in a list of groff names if a com‐
ment is included, e.g.,
3 0023 # # number sign
or
3 0023 # sh # number sign
rather than
3 0023 sh # # number sign
which will treat the first ‘#’ as the beginning of the comment.
The groff font file is written to the specified output-font; if this
operand is ‘-’, the font file is written to the standard output.
The -s option should be given if the font is special (a font is “spe‐
cial” if groff should search it whenever a character is not found in
the current font). If the font is special, it should be listed in
the fonts command in the DESC file; if it is not special, there is no
need to list it, since groff can automatically mount it when it's
first used.
If the -i option is used, hpftodit automatically will generate an
italic correction, a left italic correction and a subscript correc‐
tion for each character (the significance of these parameters is
explained in groff_font(5)).
-a Include characters in the TFM file that are not included in
map-file. A glyph with corresponding Unicode value is given
the name uXXXX; a glyph without a Unicode value is included as
an unnamed glyph ‘---’. A glyph with a Unicode value in the
Private Use Area (0xE000–0xF8FF) also is included as an
unnamed glyph.
This option provides a simple means of adding Unicode-named
and unnamed glyphs to a font without including them in the map
file, but it affords little control over which glyphs are
placed in a regular font and which are placed in a special
font. The presence or absence of the -s option has some
effect on which glyphs are included: without the -s option,
only the “text” symbol sets are searched for matching glyphs;
with the -s option, only the “mathematical” symbol sets are
searched. Nonetheless, restricting the symbol sets searched
isn't very selective—many glyphs are placed in both regular
and special fonts. Normally, the -a option should be used
only as a last resort.
-d Dump information about the TFM file to the standard output;
this option can be useful for ensuring that a TFM file is a
proper match for a font, and that the contents of the TFM file
are suitable. The information includes the values of
important TFM tags, and a listing (by MSL number for
Intellifont TFM files or by Unicode value for TrueType TFM
files) of the glyphs included in the TFM file. The unit of
measure ‘DU’ for some tags indicates design units; there are
8782 design units per em for Intellifont fonts, and
2048 design units per em for TrueType fonts. Note that the
accessibility of a glyph depends on its inclusion in a symbol
set; some TFM files list many glyphs but only a few symbol
sets.
The glyph listing includes the glyph index within the TFM
file, the MSL or Unicode value, and the symbol set and
character code that will be used to print the glyph. If map-
file is given, groff names are given for matching glyphs. If
only the glyph index and MSL or Unicode value are given, the
glyph does not appear in any supported symbol set and cannot
be printed.
With the -d option, map-file is optional, and output-font is
ignored if given.
-q Suppress warnings about characters in the map file that were
not found in the TFM file. Warnings never are given for
unnamed glyphs or by glyphs named by their Unicode values.
This option is useful when sending the output of hpftodit to
the standard output.
-v Print the hpftodit version number and exit.
-s The font is special. This option adds the special command to
the font file, and affects the order in which HP symbol sets
are searched for each glyph. Without the -s option, the
“text” sets are searched before the “mathematical” symbol
sets. With the -s option, the search order is reversed.
-in Generate an italic correction for each character so that the
character's width plus the character's italic correction is
equal to n thousandths of an em plus the amount by which the
right edge of the character's bounding is to the right of the
character's origin. If this would result in a negative italic
correction, use a zero italic correction instead.
Also generate a subscript correction equal to the product of
the tangent of the slant of the font and four fifths of the x-
height of the font. If this would result in a subscript
correction greater than the italic correction, use a subscript
correction equal to the italic correction instead.
Also generate a left italic correction for each character
equal to n thousandths of an em plus the amount by which the
left edge of the character's bounding box is to the left of
the character's origin. The left italic correction may be
negative.
This option normally is needed only with italic or oblique
fonts; a value of 50 (0.05 em) usually is a reasonable choice.
