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 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 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 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
              origin.  The left italic correction may be negative.


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

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

       /usr/local/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.
