SYNTHETIC(1)

💖 SYNTHETIC 💖

okay bestie, welcome to SYNTHETIC(1) — aka the User Commands corner of the manual, and honestly? she's a whole vibe. we're talking Synthetic, the synthetic device model test chart reader. yes that's a mouthful, no we're not shortening it, it's iconic. 🎀

✨ NAME ✨

Synthetic — Synthetic device model test chart reader. that's it, that's the name, she said what she said. 💅

🦋 DESCRIPTION 🦋

Synthetic device model test chart reader — Version 1.6.3 ✨

that's the whole description bestie. short, sweet, serving main character energy and absolutely no notes. 🫶

🌸 SYNOPSIS 🌸

here's the shape of the whole thing, look at her go:

synthread [-v] [-s] [separation.icm] profile.[icc|mpp|ti3] outfile

so you've got your flags, you've maybe got a separation profile, you've definitely got a profile, and you've got an outfile. that's the whole recipe, no cap. 🧚

💜 the flags, one by one, no skipping

• -v — Verbose mode. she talks more. we love a chatty queen. 🗣️
• -p — Use separation profile. yep, that's what it does. 🍓
• -l — Construct and output in Lab rather than XYZ. Lab girlies rise. 👑
• -i p1,p2,p3, — Set input channel curve powers (default 1.0). three powers, comma-separated, and yes there's a trailing comma in the syntax, we don't make the rules. ⭐
• -k x1:y1,x2:y2,x3:y2 — Set input channel inflection points (default 0.5,0.5). three x:y pairs, colon between them, commas between the pairs. also there's a trailing comma situation in the -i/-o ones, not here, keep up bestie. 🎀
• -o p1,p2,p3, — Set output channel curve powers (default 1.0). same energy as -i but for the output side. balance. 🌈
• -r level — Add average random deviation of <level>% to input device values (after sep.). so like, chaos, but measured, and it happens after the sep step. 💀
• -R level — Add average random deviation of <level>% to output PCS values. capital R bestie, capital R. she's the output PCS version of -r, do not confuse them, they are not twins. 🙈
• -u — Make random deviations have uniform distributions rather than normal. so your randomness gets a whole different shape. ✨
• -b L,a,b — Scale black point to target Lab value. black point, meet target. 🤝
• [separation.icm] — Device link separation profile. that's the bracketed one, the optional one, the little bonus. 💖
• profile.[icc|mpp|ti3] — ICC, MPP profile or TI3 to use. pick your fighter. 🔥
• outfile — Base name for input[ti1]/output[ti3] file. she's not a full filename, she's a base name, and she grows into those other files. lowkey iconic. 💅

real talk: that synopsis has a -s in it and the option list doesn't describe -s. we are reporting this, not explaining it, because guessing at behaviour is not the move. 🫶
