NAME

       afmtodit - create font files for use with groff -Tps

SYNOPSIS

       afmtodit [-ckmnsvx] [-a n] [-d desc_file] [-e enc_file] [-f internal_name] [-i n]
                [-o out_file] afm_file map_file font

       The whitespace between a command line option and its argument is optional.

DESCRIPTION

       afmtodit creates a font file for use with groff and grops.  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 `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.  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/share/groff/1.21/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

       -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 PS 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.

       -oout_file
              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.
