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

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

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

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 giv-
       ing  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  sub-
	      script 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/share/groff/1.18.1/font/devlj4/DESC  Device description file.

       /usr/share/groff/1.18.1/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.
