DESCRIPTION

       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 for 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.  If option -e is not 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.

       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/1.22.4/
       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 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.

OPTIONS

       Whitespace is permitted between a command-line option and its argument.

       -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 PostScript font.

       -ddesc-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).

       -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).  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.

       -ooutput-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.  The effect of this option is to add the special command to the font file.

       -v     Print version and exit.

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