DESCRIPTION         top

       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

              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 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 ‘’; 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 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)

OPTIONS         top

       -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
              constant-width fonts.

       -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.
