HDIFFTOPAM(1)

✨ NAME ✨

okay bestie, meet hdifftopam — the icon, the legend. it converts a horizontal difference image back into the original PAM image 💖

---

🌸 SYNOPSIS 🌸

hdifftopam[pamfile] [-pnm] [-verbose]

a couple lil house rules so you don't get lost, no cap:

• Minimum unique abbreviation of option is acceptable — so like, you can shorten stuff as long as it's still unambiguous, periodt.
• You may use double hyphens instead of single hyphen to denote options. both vibes are valid 💅
• You may use white space in place of the equals sign to separate an option name from its value. do whatever feels right.

---

🦋 DESCRIPTION 🦋

so this program is part of Netpbm(1) — one of the family, iykyk.

hdifftopam undoes what pamtohdiff does. that's it, that's the whole job. it's the literal reverse button, lowkey iconic 💫

💅 OPTIONS 💅

on top of the options common to all programs based on libnetpbm (most notably -quiet, see Common Options) 🫶, hdifftopam recognizes these:

• -pnm — this one tells hdifftopam to create a PNM image (i.e. PGM or PPM). skip it and hdifftopam makes a PAM image instead, with a tuple type of "unhdiff". and here's the tea: if the PAM doesn't have the proper depth to be a PGM or a PPM (i.e. 1 or 3) and you still specify -pnm, hdifftopam fails. 💀 so know your depth, bestie.
• -verbose — prints the output image width, height, depth and maxval to standard error. receipts on the screen, love that for us ✨
