💖 St4topgm User Manual 💖 — the General Commands Manual page, bestie edition ✨

okay so picture this: it's the General Commands Manual, and the star of the show is st4topgm, aka the St4topgm User Manual. let's get into it 🫶

✨ NAME ✨

st4topgm — convert an SBIG ST-4 camera file to PGM 🦋

---

🌸 SYNOPSIS 🌸

st4topgm

[st4file]

---

💅 DESCRIPTION 💅

This program is part of Netpbm(1). it's giving ✨one of the family✨.

st4topgm reads an image file in the native format used by the Santa Barbara Instrument Group (SBIG) ST-4 astronomical CCD cameras, and produces a PGM image as output. like, in goes the telescope-camera file, out comes a PGM. iconic behavior, no notes. 👑

do NOT confuse this format with the format most other SBIG cameras use, bestie — that one is a whole different vibe. for those you wanna use sbigtopgm instead. 🙈

if you're thirsty for more info on SBIG cameras and actual documentation of the file format, it lives at the Web site, http://www.sbig.com/ . go forth and read 📖✨

🎀 OPTIONS 🎀

so like… there are no command line options defined specifically for st4topgm. none. zero. the girl is a minimalist. 💅

• but she does recognize the options common to all programs based on libnetpbm — (See Common Options .) — so those are in the mix too 🫶

💀 HISTORY 💀

bestie, this is a whole saga, sit down 🍓

Bryan Henderson wrote st4topgm for Sourceforge Netpbm in January 2015. but plot twist — there had already been another program by the same name for the same purpose since December 2003, living in the Debian version of Netpbm. that one was written by Justin Pryzby <justinpryzby@users.sf.net>. two girls, one name, both doing the exact same job 😭

Bryan found out about the Debian version when Prophet of the Way did a comparison of the two Netpbms in January 2015. and get this — it was the only program that the Debian version had that the Netpbm version did not (not counting one that really didn't belong in any Netpbm, like, ma'am, why are you here 💀). so Bryan decided to add it. periodt.

and because it was a small program, Bryan decided to write a replacement in the Netpbm coding style rather than just copy Pryzby's code — but he endeavoured to keep the same function. respect. 🫶✨
