       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

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


       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.
