Описание (Description)
hpftodit creates a font 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 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.,
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 stream.
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)).
Параметры (Options)
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-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) 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 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
stream; 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.
-i n 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.
-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 stream.
-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.
