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 argu-
ment is optional.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 con-
tain a sequence of lines of the formps_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 inthe `devps/generate' subdirectory of the default font direc-
tory. If a PostScript character is not named as uniXXXX (XXXX are four uppercase hexadecimal digits), and is not mentioned inmap_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 bythe \N escape sequence in troff. If option -e is not speci-
fied, the encoding defined in the AFM file (i.e., entrieswith non-negative character codes) is used. Please refer to
section `Using Symbols' in the groff info file which describes how groff glyph names are constructed. Characters not encoded in the AFM file (i.e., entries whichhave -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. Groff Version 1.19.2Last change: 21 October 2010 1 User Commands AFMTODIT(1) 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/1.19.2/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 ofthese parameters is explained in groff_font(5)); these
parameters may be specified for individual characters byadding 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-an Use n as the slant parameter in the font file; this is
used by groff in the positioning of accents. Bydefault 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 direc-
tory, the `devps' subdirectory of the default font directory is searched (this is true for both the default device description file and a file given withoption -d).
-eenc_file
The PostScript font should be reencoded to use theencoding 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.-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 Groff Version 1.19.2Last change: 21 October 2010 2 User Commands AFMTODIT(1) 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 pro-
duct of the tangent of the slant of the font and fourfifths 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 charac-
ter 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 italiccorrection may be negative unless option -m is given.
This option is normally needed only with italic (or oblique) fonts. The font files distributed with groffwere 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 geqn(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.
