!!NAME


hpftodit - create font description files for use with groff -Tlj4
!!SYNOPSIS


__hpftodit__ [[ __-sv__ ] [[ __-i__''n'' ]
''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 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.


__-i__''n''


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/share/groff/1.17.2/font/devlj4/DESC__


Device description file.


__/usr/share/groff/1.17.2/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.
