HPFTODIT(1)                                                        HPFTODIT(1)

       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 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
       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 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

       -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 correc-
              tion, 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.

       /usr/share/groff/     Font description file for font F.

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

       TrueType tfm files are not supported.
