T1DISASM(1)

✨ T1DISASM ✨

okay bestie, welcome to the t1disasm page from the General Commands Manual — she's the one who takes your cute little PostScript Type 1 font and cracks it open so you can actually read her 💅

---

🌸 NAME 🌸

t1disasm — disassemble PostScript Type 1 font, no cap 🫶

---

🦋 SYNOPSIS 🦋

t1disasm [input [output]]

---

✨ DESCRIPTION ✨

so like. t1disasm disassembles Adobe Type 1 font programs — whether they're in PFA (that's the hexadecimal one) or PFB (the binary one) format — and turns them into human-readable form 🎀

• if you don't specify the output file, the output just goes straight to the standard output
• and if you don't specify the input file, the input comes from the standard input

periodt 💅

t1disasm performs eexec and charstring decryption exactly as specified in the ``black book'', Adobe Type 1 Font Format. and on top of that, the charstring binary tokens get expanded into human-readable text form, using the names given in the black book and later documents describing Type 2 opcodes. she's thorough, she's giving main character energy, she ate 🔥
