PAMWIPEOUT(1)

💖 pamwipeout — the Pamwipeout User Manual, section 1, General Commands Manual 💖

okay bestie, gather round, because this one is genuinely so cute and useful 🫶

✨ NAME ✨

pamwipeout — replaces the detail with a smooth gradient going from one edge all the way to the other 🌈

---

🌸 SYNOPSIS 🌸

pamwipeout {-lr | -tb} [filename]

little pro tip from me to you: you can totally use the minimum unique abbreviation of any option, like it's fine, the program gets it. and you're allowed to use double hyphens instead of a single hyphen when you're denoting options, no cap 💅

---

🦋 DESCRIPTION 🦋

so this program is part of Netpbm(1), periodt.

what pamwipeout does is it takes every row or every column (whichever one you directed it to do, bestie) and replaces it with a smooth gradient running between the pixel values at each edge. that's it, that's the whole vibe. 🌈

and the way you'd actually use this: pair it up with pamcut and pnmpaste / pamcomp to get rid of the parts of a bigger image you don't want. iconic combo honestly.

okay now here's the important tea ☕ — the two modes work very differently under the hood:

• in top-bottom mode, the program has to read the whole image into memory before it can even start processing. so it's giving "loading screen energy" for a bit there. 😭
• in left-right mode it reads the image a row at the time, processes that row, and writes it right out to the output file. streamy queen. ✨

so lowkey, if you're dealing with very large images, it might be better to use a pipe like this instead of pamwipeout -tb:

pamflip -cw | pamwipeout -lr | pamflip -ccw

fr fr, that's the move for giant images — spin it left-right and flip around it instead of loading everything into RAM. no notes. 💀

🎀 PARAMETERS 🎀

• Filename — this is the name of the input file. and if you don't specify it? pamwipeout just reads the image from Standard Input. she's flexible like that 💅

---

✨ OPTIONS ✨

so in addition to all the options that are common to every program based on libnetpbm — most notably -quiet, see Common Options — pamwipeout recognizes the following command line options:

• -tb | -lr — this option chooses between a vertical and a horizontal gradient. and listen, you must specify one of these, but not both. pick a lane bestie, you cannot have both, that's not the vibe. 🙈
