NAME

       afm2afm - reencode an afm file

SYNOPSIS

       afm2afm [-help] [-version] [-encoding=<encodingfile>] [-kpx=<kpxfile>] [-output=<outputfile>] <afmfile>

DESCRIPTION

       afm2afm re-encodes an afm file.

       Metrics  (including kerning data) for characters not present in the chosen encoding are excluded from the
       output, which resuls in (potentially much) smaller files.

       Additional kerning pairs can be added to the output file.  If you don't specify an encoding file, the afm
       file isn't re-encoded; however, all unused (unencoded) data is still pruned.

       The program also generates an entry for a dvips-style map file, but only if the afm  file  has  been  re-
       encoded  and  the  output  was  written  to  file  (i.e.,  if both the -encoding and -output options were
       specified).

OPTIONS AND ARGUMENTS

       -help
           Print a short description of the syntax

       -version
           Print version number and exit

       -encoding=<encodingfile>
           Re-encode to the enconding in <encodingfile>

       -kpx=<kpxfile>
           Read additional kerning pairs from <kpxfile> and add these to the output.  This option cannot be used
           to override values from the input afm file, since afm2afm will write both old and new values  to  the
           output!

           The  <kpxfile>  should  contain kerning data in standard afm format, i.e. for each kerning pair there
           should be a line

               KPX <left_glyph> <right_glyph> <amount>

           All other lines in the <kpxfile> are ignored.

       -output=<outputfile>
           Write the result to <outputfile> instead of "stdout".

       <afmfile>
           The afm file to be re-encoded.

       You may use either one or two dashes before options, and option  names  may  be  shortened  to  a  unique
       prefix.
