NAME¶
hpftodit - create font description files for use with groff -Tlj4
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 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 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 whitespace; the Unicode value must use uppercase
digits A–F, and must be without a leading `0x', `u', or `U+'. Unicode
values 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 u
XXXX 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 comment.
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 generate 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 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 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 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.
