SYNOPSIS
hpftodit [ -adqsv ] [ -in ] tfm_file map_file font
It is possible to have whitespace between the -i option and
its parameter.
DESCRIPTION
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 True-
Type TFM files are supported, but symbol set TFM files are
not. map_file is a file giving the groff names for charac-
ters 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 number 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. The values can be separated by any white-
space; 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 `#'
following 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 comment 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 com-
ment.
font is the name of the groff font file. The groff font
file is written to font; if font is specified as `-', the
output is written to the standard output.
The -s option should be given if the font is special (a font
is special if troff 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 troff
can automatically mount it when it's first used.
If the -i option is used, hpftodit automatically will gener-
ate an italic correction, a left italic correction and a
subscript correction for each character (the significance of
these parameters is explained in groff_font(5)).
OPTIONS
-a Include characters in the TFM file that are not
included in the 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 list-
ing (by MSL number for Intellifont TFM files or by Uni-
code 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 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.
-s The font is special. This option adds the special com-
mand 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 prod-
uct 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 charac-
ter 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.
