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

SYNOPSIS
       afmtodit	[-mnsvx] [-a n]	[-d desc_file] [-e enc_file] [-i n] afm_file
		map_file font

       The whitespace between an command line option and its argument  is  op-
       tional.

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	named as uniXXXX (XXXX are four	upper-
       case  hexadecimal  digits),  and	 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  ac-
       cessed  by the \N escape	sequence in troff.  If option -e is not	speci-
       fied, the encoding defined in the AFM file (i.e., entries with non-neg-
       ative  character	 codes)	 is used.  Please refer	to section `Using Sym-
       bols' 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.

       If there	is a downloadable font file for	the font, it may be listed  in
       the file	/usr/share/groff_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 de-
       sired 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.

       -ddesc_file
	      The device description file is desc_file rather than the default
	      DESC.  If	not found in the current directory, the	`devps'	subdi-
	      rectory 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  de-
	      scribed  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.

       -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  charac-
	      ter'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.

       -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.
