💖 LINKICC(1) 💖

okay bestie, so this is a page from the General Commands Manual — welcome to linkicc, you're gonna be obsessed 🫶

✨ NAME ✨

linkicc — little cms device link generator. that's it, that's the whole name, and honestly? iconic.

🌸 SYNOPSIS 🌸

linkicc [options] profiles

🦋 DESCRIPTION 🦋

so. lcms is a standalone CMM engine, and what it does is deal with the color management. it implements a fast transformation between ICC profiles. and linkicc? linkicc is a little cms device link generator. periodt. 💅

what it actually does: links two or more profiles into a single devicelink profile. the way that colorspaces have to be paired except Lab/XYZ, which can be interchanged. no cap, that's the whole rule. 🎀

💜 OPTIONS 💜

  • -a NUM — observer adaptation state (abs.col. only), and it takes a float value from 0..1.0. defaults to 1.0. ✨
  • -b — black point compensation. just turn it on, bestie.
  • -c precision — precision! 0=LowRes, 1=Normal, 2=Hi-res. defaults to 1.
  • -d description — description text. yes you can use quotes. go off. 💬
  • -h NUM — show a summary of options and examples. 0=help, 1=Built-in profiles, 2=Examples, 3=Contact information. it's giving menu energy.
  • -k inklimit — ink-limiting in % (CMYK only), float value from 0..400.0. default is 400.0.
  • -l — use linearization curves. > heads up: this may affect accuracy. not being dramatic, it literally says that. 😭
  • -n gridpoints — an alternate way to set precision: number of CLUT points.
  • -o profile — output devicelink profile. defaults to 'devicelink.icm'. 📁
  • -r profileversion — profile version, float value from 2.0..4.3. defaults to 4.3. > CAUTION: may change the profile implementation. like, actually. read it twice.
  • -t NUM — rendering intent. the options are:
    • 0=Perceptual [default]
    • 1=Relative colorimetric
    • 2=Saturation
    • 3=Absolute colorimetric
    • 10=Perceptual preserving black ink
    • 11=Relative colorimetric preserving black ink
    • 12=Saturation preserving black ink
    • 13=Perceptual preserving black plane
    • 14=Relative colorimetric preserving black plane
    • 15=Saturation preserving black plane
  • -v verbosity — verbosity level, 0=None, 1=Normal, 2=High, 3=Very High. defaults to 0.
  • -x — creatively, guess deviceclass of resulting profile. yes the word "creatively" is literally in the manpage, we love a chaotic queen. 🔥
  • -y copyright — copyright notice. quotes can be used. default is "No copyright, use freely" — honestly such a generous vibe.
  • -8 — creates 8-bit devicelink.

🌈 BUILT-IN PROFILES 🌈

  • *Lab2 — D50-based v2 CIEL*a*b
  • *Lab4 — D50-based v4 CIEL*a*b
  • *Lab — D50-based v4 CIEL*a*b
  • *XYZ — CIE XYZ (PCS)
  • *sRGB — sRGB color space
  • *Gray22 — Monochrome of Gamma 2.2
  • *Gray30 — Monochrome of Gamma 3.0
  • *null — Monochrome black for all input
  • *Lin2222 — CMYK linearization of gamma 2.2 on each channel

(the * in front is doing main character energy, don't skip it 🧚)

🎀 EXAMPLES 🎀

to create 'devicelink.icm' from a.icc to b.icc:

linkicc a.icc b.icc

to create 'out.icc' from sRGB to cmyk.icc:

linkicc -o out.icc *sRGB cmyk.icc

to create a sRGB input profile working in Lab:

linkicc -x -o sRGBLab.icc *sRGB *Lab

to create a XYZ -> sRGB output profile:

linkicc -x -o sRGBLab.icc *XYZ *sRGB

to create a abstract profile doing softproof for cmyk.icc:

linkicc -t1 -x -o softproof.icc *Lab cmyk.icc cmyk.icc *Lab

to create a 'grayer' sRGB input profile:

linkicc -x -o grayer.icc *sRGB gray.icc gray.icc *Lab

to embed ink limiting into a cmyk output profile:

linkicc -x -o cmyklimited.icc -k 250 cmyk.icc *Lab

okay and the little sign-off at the bottom of the page said it's from September 30, 2004, and yeah, LINKICC(1) again because that's just how manpages say goodbye. slay, go make some devicelinks bestie 💅✨
