AFM2AFM(1)

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.
