NAME
       hpftodit  -  create  font  description  files for use with
       groff -Tlj4

SYNOPSIS
       hpftodit [ -sv ] [ -in ] tfm_file map_file font

DESCRIPTION
       hpftodit creates a font file for use with groff -Tlj4 from
       an  HP  tagged  font metric file.  tfm_file is the name of
       the tagged font metric file for the font.  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:

              n c1 c2 ...

       where  n is a decimal integer giving the MSL number of the
       character, and c1, c2,...  are  the  groff  names  of  the
       character.   font is the name of the groff font file.  The
       groff font file is written to font.

       The -s option should be given if the font  is  special  (a
       font is special if troff should search it whenever a char-
       acter 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 will automatically gen-
       erate 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
       -v     Print the version number.

       -s     The  font is special.  The effect of this option is
              to add the special command to the font file.

       -in    Generate an italic correction for each character so
              that  the  character's  width  plus the character's
              italic correction is equal to n design  units  plus
              the  amount  by which the right edge of the charac-
              ter'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.
              There  are 8782 design units per em for Intellifont
              fonts.

              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 design units 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 is normally needed only with italic (or
              oblique) fonts.

FILES
       /usr/share/groff_font/devlj4/DESC
              Device description file.

       /usr/share/groff_font/devlj4/F
              Font description file for font F.

BUGS
       This program was written without the benefit of  complete,
       official  documentation  on the tagged font metric format.
       It is therefore likely that it will fail to  work  on  tfm
       files  that are dissimilar to those for the internal fonts
       on the Laserjet 4, with which it was tested:

       TrueType tfm files are not supported.
