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.,
              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.

       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.
