🎀 SYNOPSIS 🎀

openslide-quickhash1sum [--help] [--version] slide...

like. that's it. that's the whole vibe. feed it some slides 🦋

---

💜 DESCRIPTION 💜

So what this does is it prints OpenSlide quickhash-1 checksums for one or more virtual slide files, in a format that's giving very sha256sum(1) energy 🫶

Now, quickhash-1 is a non-cryptographic, 256-bit hash of a subset of a slide's data. It uniquely identifies a particular virtual slide, bestie — but lowkey it cannot be used to detect corruption or modification of the slide file. So don't come for it about integrity checks, that is not its job 🙈

✨ OPTIONS ✨

• --help — shows you the usage summary, your little map 🗺️
• --version — spills the version and the copyright info 👑

---

💀 EXIT STATUS 💀

• returns 0 when it's all slay, success ✅
• returns 1 if a quickhash-1 could not be calculated 😭
• returns 2 if the arguments are invalid 💀

🧚 NOTES 🧚

ngl, openslide-quickhash1sum is a legacy command and no new features will be added. periodt. Its replacement is the slide quickhash1 subcommand of slidetool(1). so like… go there eventually bestie 💅

---

🍓 BUGS 🍓

quickhash-1 is not defined for all slide files supported by OpenSlide. If a slide does not have a quickhash-1, "No quickhash-1 available" will be printed. that's the whole heads-up 🫶
