The whitespace between a command line option and its argument is
afmtodit creates a font file for use with groff, grops, and gropdf.
afmtodit is written in perl; you must have perl version 5.004 or
newer 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. Lines starting with # and blank
lines are ignored. If the file isn't found in the current directory,
it is searched in the ‘devps/generate’ subdirectory of the default
If a PostScript character is not mentioned in map_file, and a generic
groff glyph name can't be deduced using the Adobe Glyph List (AGL,
built into afmtodit), then afmtodit puts the PostScript character
into the groff font file as an unnamed character which can only be
accessed by the \N escape sequence in troff. In particular, this is
true for glyph variants like ‘foo.bar’; all glyph names containing
one or more periods are mapped to unnamed entities. If option -e is
not specified, the encoding defined in the AFM file (i.e., entries
with non-negative character codes) is used. Please refer to section
‘Using Symbols’ in the groff info file which describes how groff
glyph names are constructed.
Characters not encoded in the AFM file (i.e., entries which have -1
as the character code) are still available in groff; they get glyph
index values greater than 255 (or greater than the biggest character
code used in the AFM file in the unlikely case that it is greater
than 255) in the groff font file. Glyph indices of unencoded
characters don't have a specific order; it is best to access them
with glyph names only.
The groff font file will be output to a file called font, unless the
-o option is used.
If there is a downloadable font file for the font, it may be listed
in the file /usr/local/share/groff/1.22.3/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 nleftItalicCorrection ps_char nsubscriptCorrection 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)
-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
-c Include comments in the font file in order to identify the PS
The device description file is desc_file rather than the
default DESC. If not found in the current directory, the
‘devps subdirectory of the default font directory is searched
(this is true for both the default device description file and
a file given with option -d).
The PostScript font should be reencoded to use the encoding
described in enc_file. The format of enc_file is described in
grops(1). If not found in the current directory, the ‘devps’
subdirectory of the default font directory is searched.
-fname The internal name of the groff font is set to name.
-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 box 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 character's origin. The left italic correction may be
negative unless option -m is given.
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.
The output file is out_file instead of font.
-k Omit any kerning data from the groff font. This should be
used only for mono-spaced fonts.
-m Prevent negative left italic correction values. Roman font
files distributed with groff were created with -i0 -m to
improve spacing with eqn(1).
-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.
-v Print version.
-x Don't use the built-in Adobe Glyph List.
