afmtodit creates a font file for use with groff and grops. 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 font directory.
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 con-
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/share/groff/1.21/font/devps/download; see grops(1).
-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.
-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' subdi-
rectory 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 charac-
ter'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.
