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 4series (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 arenot. 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 namesof the character. The values can be separated by any whi-
tespace; the Unicode value must use uppercase digits AF, 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 glyphcorresponds to a Unicode value, or as an unnamed glyph `---
'. If the given Unicode value is in the Private Use Area (0xE0000xF8FF), 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
or3 0023 # sh # number sign
rather than3 0023 sh # # number sign
Groff Version 1.19.2Last change: 21 October 2010 1 User Commands HPFTODIT(1)which will treat the first `#' as the beginning of the com-
ment. font is the name of the groff font file. The groff fontfile 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 gen-
erate an italic correction, a left italic correction and a subscript correction for each character (the significance ofthese 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 withouta Unicode value is included as an unnamed glyph `---'.
A glyph with a Unicode value in the Private Use Area (0xE0000xF8FF) 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 orabsence 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; withthe -s option, only the mathematical symbol sets are
searched. Nonetheless, restricting the symbol setssearched 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 informationincludes the values of important TFM tags, and a list-
ing (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 Groff Version 1.19.2Last change: 21 October 2010 2 User Commands HPFTODIT(1) 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 theglyph. 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 theoutput 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. Withoutthe -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 pro-
duct of the tangent of the slant of the font and fourfifths 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 Groff Version 1.19.2Last change: 21 October 2010 3 User Commands HPFTODIT(1) oblique fonts; a value of 50 (0.05 em) usually is a reasonable choice.
