PNMINVERT(1)

✨ pnminvert ✨

okay so bestie, welcome to the Pnminvert User Manual 💖 (that's the (1) section, general commands, iykyk)

🌸 NAME 🌸

pnminvert — invert a PNM image 🫶

---

🎀 SYNOPSIS 🎀

pnminvert

[pnmfile]

yes that's the whole thing. no flags, no drama, just vibes ✨

---

💅 DESCRIPTION 💅

okay so first things first: this program is part of Netpbm(1) — you know, the whole big family 💖

pnminvert reads a PNM image as input, inverts it black for white, and produces a PNM image as output. literally the glow-up reversal arc 😭🦋

If the image is grayscale, pnminvert replaces a pixel with one of complementary brightness, i.e. if the original pixel has gamma-adjusted gray value G, the output pixel has gray value maxval - G. math girlies rise 🙈

If the image is color, pnminvert inverts each individual RGB component the same as for a grayscale image. all three channels get the same treatment, no favorites 🎀🌈

---

⭐ OPTIONS ⭐

There are no command line options defined specifically for pnminvert, but it recognizes the options common to all programs based on libnetpbm (See Common Options.) 👑

so like… zero bespoke flags. it's an icon of minimalism 💅✨
