SYNOPSIS    [Toc]    [Back]

       tfmtodit [ -sv ] [ -ggf_file ] [ -kskewchar ] tfm_file
                map_file font

       It is possible to have whitespace between a  command  line
       option and its parameter.

DESCRIPTION    [Toc]    [Back]

       tfmtodit  creates  a  font  file for use with groff -Tdvi.
       tfm_file is the name of the TeX font metric file  for  the
       font.  map_file is a file giving the groff names for characters
 in the font; this file should consist of a sequence
       of lines of the form:

              n c1 c2 ...

       where  n  is  a decimal integer giving the position of the
       character in the font, and c1, c2,...  are the groff names
       of  the  character.  If a character has no groff names but
       exists in the tfm file, then it will be put in  the  groff
       font  file  as  an unnamed character.  font is the name of
       the groff font file.  The groff font file  is  written  to
       font.

       The  -s  option  should be given if the font is special (a
       font is special if troff should search it whenever a character
  is  not found in the current font.)  If the font is
       special, it should be listed in the fonts command  in  the
       DESC  file; if it is not special, there is no need to list
       it, since troff can automatically mount it when it's first
       used.

       To  do a good job of math typesetting, groff requires font
       metric information not present in the tfm file.  The  reason
  for  this  is that TeX has separate math italic fonts
       whereas groff uses normal  italic  fonts  for  math.   The
       additional  information  required by groff is given by the
       two arguments to the math_fit macro in the  Metafont  programs
  for  the  Computer Modern fonts.  In a text font (a
       font for which math_fitting is false),  Metafont  normally
       ignores  these two arguments.  Metafont can be made to put
       this information in the gf file by loading  the  following
       definition after cmbase when creating cm.base:

              def ignore_math_fit(expr left_adjustment,right_adjustment) =
                  special "adjustment";
                  numspecial left_adjustment*16/designsize;
                  numspecial right_adjustment*16/designsize;
                  enddef;

       The  gf file created using this modified cm.base should be
       specified with the -g option.  The -g option should not be
       given for a font for which math_fitting is true.

OPTIONS    [Toc]    [Back]

       -v     Print the version number.

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

       -kn    The skewchar of this font  is  at  position  n.   n
              should  be  an integer; it may be given in decimal,
              or with a leading 0 in octal, or with a leading  0x
              in  hexadecimal.   The  effect of this option is to
              ignore any kerns  whose  second  component  is  the
              specified character.

       -ggf_file
              gf_file  is a gf file produced by Metafont containing
 special and numspecial  commands  giving  additional
 font metric information.
