hpftodit - create font description files for use with
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 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
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
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
Device description file.
Font description file for font F.
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.
