NAME
afmtodit - create font files for use with groff -Tps
SYNOPSIS
afmtodit [ -nsv ] [ -d desc_file ] [
-e enc_file ] [ -i n ] [ -a
n ] afm_file map_file font
DESCRIPTION
afmtodit creates a font file for use
with groff and grops. afmtodit is written in perl;
you must have perl version 3 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
- ps_char groff_char
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.
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/1.18.1.1/font/devps/download; see
grops(1).
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 (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.
OPTIONS
- -v
- Print version.
- -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 to add the
special command to the font file.
- -ddesc_file
- The device description file is desc_file rather than the
default DESC.
- -eenc_file
- 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 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
character'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.
