PPMSPREAD(1)

💖 ppmspread — Ppmspread User Manual, section 1 💖

okay bestie, sit down, hydrate, and let me tell you about ppmspread 🌸 this is the Ppmspread User Manual, section 1, and it's giving "shuffle my pixels, but make it chaos" ✨

---

✨ NAME ✨

ppmspread — displace a PPM image's pixels by a random amount 🎲

---

🦋 SYNOPSIS 🦋

ppmspread amount [ppmfile] [-randomseed=integer]

---

💅 DESCRIPTION 💅

okay so first thing: this program is part of Netpbm(1), iykyk 🫶

ppmspread reads a PPM image as input and moves every single pixel around a random bit relative to its original position. literally every pixel gets its own little main character moment and wanders off 😭

amount determines by how many pixels a pixel is to be moved around at most. that's the ceiling, the limit, the vibe check — nobody moves further than that 👑

Pictures processed with this filter will seem to be somewhat dissolved or unfocussed — although they appear more coarse than images processed by something like pnmconvol. so like, blurry but crunchy?? it's giving sprinkled glitter on a wet photo 🍓

⚠️ lowkey important lore: the randomness in the image is limited before Netpbm 10.37 (December 2006) — if you run the program twice in the same second, you may get identical output. not a vibe. no cap. 💀

🎀 OPTIONS 🎀

In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options), ppmspread recognizes the following command line options:

• -randomseed=integer — this is the seed 🌱 for the random number generator that generates the pixels. use this to ensure you get the same image on separate invocations (obsessed, reproducible queen 💖). this option was new in Netpbm 10.94 (March 2021) ✨
