hpftodit(1) General Commands Manual hpftodit(1)
hpftodit - create font description files for use with groff and
grolj4
hpftodit [-aqs] [-i n] tfm-file map-file font-description
hpftodit -d tfm-file [map-file]
hpftodit --help
hpftodit -v
hpftodit --version
hpftodit creates a font description file for use with a Hewlett-
Packard LaserJet 4-series (or newer) printer with the grolj4(1)
output driver of groff(1), using data from an HP tagged font
metric (TFM) file. tfm-file is the name of the font's TFM file;
Intellifont and TrueType TFM files are supported, but symbol set
TFM files are not. map-file is a file giving the groff special
character identifiers for glyphs 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 glyph's MSL (Master
Symbol List) number, u is a hexadecimal integer giving its
Unicode character code, and c1, c2, ... are its groff glyph
names (see groff_char(7) for a list). The values can be
separated by any number of spaces and/or tabs. The Unicode value
must use uppercase hexadecimal digits A–F, and must lack a
leading “0x”, “u”, or “U+”. Unicode values corresponding to
composite glyphs are decomposed; that is “u00C0” becomes
“u0041_0300”. A glyph without a groff special character
identifier may be named 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 (PUA) (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, as in
3 0023 # # number sign
or
3 0023 # sh # number sign
whereas in
3 0023 sh # # number sign
the first “#” is interpreted as the beginning of the comment.
hpftodit writes output to font-description, a file named for the
intended groff font name; if this operand is “-”, hpftodit writes
to the standard output stream. The -i option directs hpftodit to
automatically generate an italic correction, a left italic
correction, and a subscript correction for each glyph. See
groff_font(5).
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-a Include glyphs 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) is
also 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 it, only the “text” symbol sets are searched for
matching glyphs; with it, 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, -a should be
used only as a last resort.
-d Dump information about the TFM file to the standard output
stream; use this to ensure that a TFM file is a proper
match for a font, and that its contents 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.
-i n Generate an italic correction for each glyph so that its
width plus its italic correction is equal to n thousandths
of an em plus the amount by which the right edge of the
glyphs's bounding box is to the right of its origin. The
minimum value hpftodit will write is zero.
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 a subscript correction
greater than the italic correction would result, use a
subscript correction equal to the italic correction
instead.
Also generate a left italic correction for each glyph
equal to n thousandths of an em plus the amount by which
the left edge of the glyphs's bounding box is to the left
of its 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.
-q Suppress warnings about glyphs 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 stream.
-s Add the special directive to the font description file,
affecting the order in which HP symbol sets are searched
for each glyph. Without this option, the “text” sets are
searched before the “mathematical” symbol sets. With it,
the search order is reversed.
/usr/local/share/groff/1.23.0/font/devlj4/DESC
describes the lj4 output device.
/usr/local/share/groff/1.23.0/font/devlj4/F
describes the font known as F on device lj4.
/usr/local/share/groff/1.23.0/font/devlj4/generate/Makefile
is a make(1) script that uses hpftodit(1) to prepare the
groff font description files above from HP TFM data; it
can be used to regenerate them in the event the TFM files
are updated.
/usr/local/share/groff/1.23.0/font/devlj4/generate/special.awk
is an awk(1) script that corrects the Intellifont-based
height metrics for several glyphs in the S (special) font
for TrueType CG Times used in the HP LaserJet 4000 and
later.
/usr/local/share/groff/1.23.0/font/devlj4/generate/special.map
/usr/local/share/groff/1.23.0/font/devlj4/generate/symbol.map
/usr/local/share/groff/1.23.0/font/devlj4/generate/text.map
/usr/local/share/groff/1.23.0/font/devlj4/generate/wingdings.map
map MSL indices and HP Unicode PUA assignments to groff
special character identifiers.
