AFM2AFM(1)

📦 version 2026.0, in alpine 3.24

🌸 AFM2AFM(1) 🌸

okay so bestie, welcome to the afm2afm page — it's section 1 of the manual, and the author is Marc Penninga. yes, that Marc Penninga. icon behavior. let's get into it 💅

✨ NAME ✨

afm2afm — reencode an afm file

like, that's the whole vibe. it reencodes an afm file. 🎀

🦋 SYNOPSIS 🦋

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

💖 DESCRIPTION 💖

so afm2afm re-encodes an afm file. that's the main character task, no cap.

Metrics (including kerning data, yes the kerning data too 🔥) for characters that aren't present in the chosen encoding get excluded from the output — which resuls in (potentially much) smaller files. tiny file, big slay. ✨

you can also add extra kerning pairs to the output file. and listen: if you don't specify an encoding file, the afm file isn't re-encoded — but all the unused (unencoded) data still gets pruned anyway. the pruning is non-negotiable, she's gonna prune. 🪴

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., only if both the -encoding and -output options were specified. both or nothing, bestie. 🫶

🌈 OPTIONS AND ARGUMENTS 🌈

  • -help — prints a short description of the syntax. little cheat sheet moment, we love her 💜
  • -version — prints the version number and exits. bye! 👋
  • -encoding=<encodingfile> — re-encode to the enconding in <encodingfile>. pick your encoding, babe 🎀
  • -kpx=<kpxfile> — read additional kerning pairs from <kpxfile> and adds these to the output. ⚠️ heads up: this option cannot be used to override values from the input afm file, because afm2afm will write both old and new values to the output! so like, both. both is what happens. 😭

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. they simply do not exist to her. 💀

  • -output=<outputfile> — write the result to <outputfile> instead of "stdout". very "i'm not like other outputs" of her ✨
  • <afmfile> — the afm file to be re-encoded. the star of the show 👑
okay and this part's important: you may use either one or two dashes before options, and option names may be shortened to a unique prefix. so like, flexible. accommodating. a queen who meets you where you're at. 🌸
