NAME
       afmtodit - create font files for use with groff -Tps

SYNOPSIS
       afmtodit  [ -ns ] [ -ddesc_file ] [ -eenc_file ] [ -in ] [
       -an ] afm_file map_file font

DESCRIPTION
       afmtodit creates a font file for use with groff and grops.
       afmtodit  is written in perl; you must have perl version 3
       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.   font  is  the  groff  name  of  the  font.   If  a
       PostScript character is in the encoding to be used for the
       font but is not mentioned in map_file then  afmtodit  will
       put  it  in  the  groff font file as an unnamed character,
       which can be accessed by the \N escape sequence in  troff.
       The  groff font file will be output to a file called font.

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

       If the -i option is used, afmtodit will automatically gen-
       erate 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
       -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.

       -ddesc_file
              The device description  file  is  desc_file  rather
              than the default DESC.

       -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).

       -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 ItalicAn-
              gle 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.

       -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 is to the right of the charac-
              ter'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 ori-
              gin.  The left italic correction may be negative.

              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.
