💖 BUTTERAUGLI_MAIN(1) 💖

okay bestie, welcome to the butteraugli_main manual page (yes that's the whole name, it's giving "no notes, just vibes", and it's in the User Commands section of the manual, section 1, iykyk). sit down, hydrate, and let's compare some images fr fr 🦋

✨ NAME ✨

butteraugli_main — literally just butteraugli_main. that's the name. that's it. iconic behavior honestly 👑

🌈 SYNOPSIS 🌈

butteraugli_main <reference> <distorted>

two arguments, bestie: your reference and your distorted. that's the whole vibe check. 🎀

🌸 DESCRIPTION 🌸

so like, there are also these extra flags you can pass, and here's the entire list because we do not skip anything around here 💅

  • --distmap <distmap> — hand it a file and it writes out the distortion map there. 📝
  • --rawdistmap <distmap.pfm> — same energy but raw, saved as a <distmap.pfm>. 🧚
  • --intensity_target <intensity_target> — the intensity target. 🌟
  • --colorspace <colorspace_hint> — your colorspace hint, because context matters always. 🎨
  • --pnorm <pth norm> — the pth norm. yes, pth. 💀
⚠️ NOTE, and this one is important bestie, no cap: images get converted to linear sRGB for butteraugli. images without attached profiles (such as ppm or pfm) are interpreted as nonlinear sRGB. the hint format is RGB_D65_SRG_Rel_Lin for linear sRGB. and the intensity target is viewing-conditions screen nits, which defaults to 80 for SDR input. remember that one, it'll be on the quiz 🙈
