afmtodit - adapt Adobe Font Metrics files for groff -Tps and -Tpdf

afmtodit converts an Adobe Font Metric file, afm-file, for use with the ps and pdf output drivers of groff(1). map-file associates a groff character name with a PostScript character name. Output is written to font, a file named for the intended groff font name (but see the -o option). afm-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 sought in the devps/generate subdirectory of the default font directory. If a PostScript character 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 accessed by the “\N” escape sequence in a roff document. In particular, this is true for glyph variants named in the form “foo.bar“; all glyph names containing one or more periods are mapped to unnamed entities. Unless -e is specified, the encoding defined in the AFM file (i.e., entries with non-negative character codes) is used. Refer to section “Using Symbols” in Groff: The GNU Implementation of troff, the groff Texinfo manual, 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. If there is a downloadable font file for the font, it may be listed in the file /usr/local/share/groff/1.23.0/font/devps/ download; see grops(1). If the -i option is used, afmtodit automatically generates an italic correction, a left italic correction, and a subscript correction for each character (the significance of these is explained in groff_font(5)); they 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. Such parameters are normally needed only for italic (or oblique) fonts.
-a n 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. -c Include comments in the font file in order to identify the PostScript font. -d desc-file The device description file is desc-file rather than the default DESC. If not found in the current directory, the devps subdirectory of the default font directory is searched (this is true for both the default device description file and a file given with option -d). -e enc-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). If not found in the current directory, the devps subdirectory of the default font directory is searched. -f name The internal name of the groff font is set to name. -i n 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 character'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. -o output-file The output file is output-file instead of font. -k Omit any kerning data from the groff font; use only for monospaced (constant-width) 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 with monospaced (constant-width) fonts. -s The font is special; add the special command to the font file. -v Write version information to the standard output stream and exit. -x Don't use the built-in Adobe Glyph List.
