NAME

       afmtodit - create font files for use with groff -Tps

SYNOPSIS

       afmtodit [ -nsv ] [ -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 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.  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/share/groff/1.18.1/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

       -v     Print version.

       -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 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.

       -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 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.

	      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.
