       afmtodit [-ckmnsx] [-a n] [-d desc-file] [-e enc-file]
                [-f internal-name] [-i n] [-o output-file] afm-file map-

Description         top

       afmtodit converts an Adobe Font Metric file, afm-file, for use
       with the ps and pdf output drivers of groff(1).  map-file
       associates a groff character name with a PostScript character
       name.  Output is written to font, a file named for the intended
       groff font name (but see the -o option).

       afm-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.  If the file isn't found in
       the current directory, it is sought 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 a roff document.  In particular, this is true for glyph
       variants named in the form “foo.bar“; all glyph names containing
       one or more periods are mapped to unnamed entities.  Unless -e is
       specified, the encoding defined in the AFM file (i.e., entries
       with non-negative character codes) is used.  Refer to section
       “Using Symbols” in Groff: The GNU Implementation of troff, the
       groff Texinfo manual, 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.

       If there is a downloadable font file for the font, it may be
       listed in the file /usr/local/share/groff/1.23.0/font/devps/
       download; see grops(1).

       If the -i option is used, afmtodit automatically generates an
       italic correction, a left italic correction, and a subscript
       correction for each character (the significance of these is
       explained in groff_font(5)); they can 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.  Such parameters are normally needed only for italic
       (or oblique) fonts.

Options         top

       -a n   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
              PostScript font.

       -d desc-file
              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).

       -e enc-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).  If not found in the current
              directory, the devps subdirectory of the default font
              directory is searched.

       -f name
              The internal name of the groff font is set to name.

       -i n   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.

       -o output-file
              The output file is output-file instead of font.

       -k     Omit any kerning data from the groff font; use only for
              monospaced (constant-width) 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 with
              monospaced (constant-width) fonts.

       -s     The font is special; add the special command to the font
              file.

       -v     Write version information to the standard output stream
              and exit.

       -x     Don't use the built-in Adobe Glyph List.
