PBMPSCALE(1)

💖 PBMPSCALE 💖

okay bestie, welcome to the Pbmpscale User Manual — yes that's the whole title, section 1, General Commands Manual, we're doing this 💅

---

✨ NAME ✨

pbmpscale — enlarge a PBM image with edge smoothing 🦋

---

✨ SYNOPSIS ✨

pbmpscale N [pbmfile]

---

✨ DESCRIPTION ✨

so first things first, this program is part of Netpbm(1). family reunion, love that for us 🫶

pbmpscale reads a PBM image as input, and outputs a PBM image enlarged N times. literally just "make it bigger" energy.

and how does it do that? by pixel replication, bestie — straight up copy-paste of pixels — plus some additional smoothing of corners and edges. so it's not just chunky blocks, it's chunky blocks that got a lil glow-up ✨

---

✨ OPTIONS ✨

okay so listen 😭 there are no command line options defined specifically for pbmpscale. none. zero. she said "I'm low maintenance."

BUT — and this is important — it recognizes the options common to all programs based on libnetpbm. (See Common Options.) so the shared bestie options apply, iykyk 👑

✨ NOTES ✨

ngl this is the tea: pbmpscale works best for enlargements of 2.

to do enlargements greater than 2, you should do as many enlargements of 2 as possible, then enlarge by the remaining factor. so like, stack those 2x's, queen 👑
