afmtodit - create font files for use with groff -Tps
afmtodit [ -ns ] [ -ddesc_file ] [ -eenc_file ] [ -in ] [
-an ] afm_file map_file font
afmtodit 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
PostScript 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 font.
If there is a downloadable font file for the font, it may
be listed in the file /usr/share/groff_font/devps/down-
load; see grops(1).
If the -i option is used, afmtodit will automatically gen-
erate 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) fonts.
-n Don't output a ligatures command for this font.
Use this with constant-width fonts.
-s The font is special. The effect of this option is
Groff Version 1.11 14 September 1996 1
to add the special command to the font file.
The device description file is desc_file rather
than the default DESC.
The PostScript font should be reencoded to use the
encoding described in enc_file. The format of
enc_file is described in 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 ItalicAn-
gle 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 charac-
ter's origin. If this would result in a negative
italic correction, use a zero italic correction
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 ori-
gin. 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
