PNGINSPECT(1p)

💅 PNGINSPECT(1p) — the pnginspect era 💅

okay so bestie, gather round, because this is a User Contributed Perl Documentation page and it's about to spill every single PNG detail. no gatekeeping here 🫶

---

✨ NAME ✨

pnginspect — print contents of PNG files. that's the whole job. she looks inside your PNG and tells you everything. iconic behavior, honestly 👑

---

🌸 SYNOPSIS 🌸

pnginspect a.png b.png c.png

yep, that's it. multiple files, one command, no drama 💖

---

🦋 DESCRIPTION 🦋

So what she actually does: she prints a text representation of the data inside a PNG image file, straight to standard output. Here's the whole glow-up sequence:

1. She reads the PNG file 📖
2. She prints out its header information and its valid chunks
3. Then she attempts to read all the chunks

Most of the chunks get printed using Data::Dumper — love that for them. But the modification time and the text segments? Those get printed specially, because they're main characters and they know it ✨

lowkey important: the image data is not currently printed out. so don't come for her about the pixels, she's simply not doing that rn 🙈

💫 examining PNGs on the web 💫

If you've got Data::Validate::URI and LWP::Simple installed, you can also use her to peep PNG files out on the internet. like this:

pnginspect http://libpng.org/pub/png/img_png/libpng-88x31.png

ngl that's kind of a slay? 🌐

⚠️ but listen: these modules are not installed automatically by Image::PNG::Libpng. so if you wanna use this facility, bestie, you gotta install them yourself. no cap. 🫶

🎀 OPTIONS 🎀

• --verbose — print verbose information for debugging. when you need her to be extra loud and tell you every little thing 🔍

---

🌈 SEE ALSO 🌈

• Image::PNG::Libpng — her ride-or-die, the whole reason she exists 🫂

and that's the page, babes. she's giving small tool, big energy, zero pixel output and a whole lot of chunks. go inspect something. periodt. 💅✨

mwah 💋 — this was perl v5.42.3, dated 2026-08-19, and she's still out here printing PNG guts like the queen she is 🌸🦋🎀
