NAME

       afmtodit - create font files for use with groff -Tps and -Tpdf

SYNOPSIS

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

       afmtodit -v

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.
