       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)

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

       /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.
