NAME¶
hpftodit - create font description files for use with groff -Tlj4
SYNOPSIS¶
hpftodit |
[-aqs] [-i
n] tfm-file map-file output-font |
hpftodit |
-d tfm-file [map-file] |
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 (Master Symbol List) 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 (see groff_char(7) for a list). 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
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.,
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 “special” 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
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
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.
