PSIDTOPGM(1)

💅 psidtopgm — the manual, but make it make sense 💅

okay so bestie, this one's a General Commands Manual page — like, the classic Unix manual energy — and it's for a little program called psidtopgm. It's part of the Netpbm family. Let's get into it ✨

---

🌸 NAME 🌸

psidtopgm — converts PostScript "image" data into a PGM image. That's it. That's the whole job. 💖

---

🦋 SYNOPSIS 🦋

psidtopgm width height bits/sample [imagedata]

---

✨ DESCRIPTION ✨

So this program is part of Netpbm(1). It reads the "image" data out of a PostScript file as input, and it produces a PGM image as output. Simple transaction. 🎀

⚠️ Heads up: this program is obsoleted by pstopnm. Like, it's the old way. The text that follows was written before pstopnm even existed. So keep that in mind, okay?

This is a very simple and limited program, and honestly? It's only here because so many people asked for it. 🙈 That's the vibe.

So the way you use it: you have to manually extract the readhexstring data portion from your PostScript file, and then you give the width, height, and bits/sample on the command line. Manual labour, but make it Unix. 💪

Before you even attempt this, bestie, you should at least read the description of the "image" operator over in the PostScript Language Reference Manual. Like, please, for your own sake. 📖

Would it be hard to write a script that uses this filter to read one specific variety of PostScript image? Probably not, ngl. But the variation out there is just too great to make a general-purpose reader. Unless… you wanna write a full-fledged PostScript interpreter? 👀 Because that's the only way. Main character energy, honestly.

💅 OPTIONS 💅

okay so the thing is — there are no command line options defined specifically for psidtopgm. Zero. None. Periodt.

But it does recognize the options common to all programs based on libnetpbm. (See Common Options.)

• no psidtopgm-specific flags — there just aren't any, and that's fine 🫶
• libnetpbm common options — these get recognized anyway, because it's a libnetpbm girlie (See Common Options.)
