💖 NAME 💖

jpegjudge — guess jpeg picture quality 🎀

✨ SYNOPSIS ✨

jpegjudge [ -V ]

jpegjudge [ -b ] file ...

🦋 DESCRIPTION 🦋

okay so bestie, jpegjudge reads every argument you hand it and tries to guess the quality the pic was saved at. no cap. 🔥

rn it only spits out a rough indicator, and that number goes from 0 (lowest quality, kinda crusty) all the way up to 1000 (highest quality, absolutely ate 💅). expanding it to other formats would honestly be straightforward, but like… it's not planned. periodt. 🙈

it can read every picture the IJG jpeg library can read, meaning normal jpegs and progressive jpegs. iconic. 👑

🌸 OPTIONS 🌸

• -b — display only the quality indicator and suppress all the other info (like filenames). minimalism, we love her 💖
• -h, --help — show a short lil summary of the options. your bestie explaining herself 🫶
• -V, --version — print the version number and dip immediately. main character exit ✨

💀 BUGS 💀

• ngl it should be possible to judge pictures stored in non-lossy formats too, since converting to jpeg can mess with the measurement. so yeah, that's a whole thing. 😭
• the quality indicator is non-linear and could be, like, so much better. it's giving "we tried". 🙈
• the algorithm that calculates the quality was literally made up in 10 minutes after staring at various histograms. that's it. that's the vibe check. 💀

🌈 ACKNOWLEDGEMENTS 🌈

this program contains code from the IJG jpeg software. shoutout to them, fr fr. 💜

okay that's the whole page bestie!! go forth and judge jpegs, you've got this 💅✨
