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

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

       It  is  possible  to have whitespace between the -i command line option
       and its parameter.

       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

              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 character is not found in the cur-
       rent 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  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)).

       -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  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.  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  ori-
              gin.  The left italic correction may be negative.

              This  option  is  normally  needed only with italic (or oblique)

       This program was written without the benefit of complete, official doc-
       umentation  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.
