SYNOPSISafmtodit [ -nsv ] [ -ddesc_file ] [ -eenc_file ] [ -in ] [ -an ]
afm_file map_file font
DESCRIPTIONafmtodit creates a font file for use with groff and grops. afmtodit is
written in perl; you must have perl version 3 installed in order to run
afmtodit. afm_file is the AFM (Adobe Font Metric) file for the font.
map_file is a file that says which groff character names map onto each
PostScript character name; this file should contain a sequence of lines
of the form
where ps_char is the PostScript name of the character and groff_char is
the groff name of the character (as used in the groff font file.) The
same ps_char can occur multiple times in the file; each groff_char must
occur at most once. font is the groff name of the font. If a Post‐
Script character is in the encoding to be used for the font but is not
mentioned in map_file then afmtodit will put it in the groff font file
as an unnamed character, which can be accessed by the \N escape
sequence in troff. The groff font file will be output to a file called
If there is a downloadable font file for the font, it may be listed in
the file /usr/local/share/groff/1.17.2/font/devps/download; see
If the -i option is used, afmtodit 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)); these parameters may be specified for individual
characters by adding to the afm_file lines of the form:
italicCorrection ps_char n
leftItalicCorrection ps_char n
subscriptCorrection ps_char n
where ps_char is the PostScript name of the character, and n is the
desired value of the corresponding parameter in thousandths of an em.
These parameters are normally needed only for italic (or oblique)
OPTIONS-v Print version.
-n Don't output a ligatures command for this font. Use this with
-s The font is special. The effect of this option is to add the
special command to the font file.
The device description file is desc_file rather than the default
The PostScript font should be reencoded to use the encoding
described in enc_file. The format of enc_file is described in
-an Use n as the slant parameter in the font file; this is used by
groff in the positioning of accents. By default afmtodit uses
the negative of the ItalicAngle specified in the afm file; with
true italic fonts it is sometimes desirable to use a slant that
is less than this. If you find that characters from an italic
font have accents placed too far to the right over them, then
use the -a option to give the font a smaller slant.
-in Generate an italic correction for each character so that the
character's width plus the character's italic correction is
equal to n thousandths of an em 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.
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 thousandths of an em plus the amount by which the left edge
of the character's bounding box is to the left of the charac‐
ter's origin. The left italic correction may be negative.
This option is normally needed only with italic (or oblique)
fonts. The font files distributed with groff were created using
an option of -i50 for italic fonts.
