David, you may try to create by target/printtarg similar target with same patch
number and dimensions as your DC SG. Use targen key to create additional scanin
data. Then use scanin and the files to recognize the target. Scanin would
complain that your image doesn't conside expected data but it will read the
target and will provide you with values. воскресенье, 10 сентября 2017г., 03:48

Thank u so much for all your ideas. I was going to do it manually but I though
140 patches!!! But that's fine. I usually use patchtool from babelcolor and I
manually type all Lab values. I could convert 140 patches in one sec with
Patchtool but is $125. Scanin is doing the hard stuff.
Thanks again,
Dave

I am trying to create a cgats file from an AdobeRGB tiff image of a

If you're just looking for L*a*b* textual data, and you're starting with
textual RGB data, you can use Argyll's xicclu. There's enough patches in the
ColorChecker SG for it to be worth a bit of work with awk / sed / your
favorite text editor to automate it...but there's not so many that you can't
do it manually (perhaps with copy / paste) if that's not your thing.
If you need to create an RGB image of a chart, you can use printtarg to
create a TIFF and then your favorite image editing software to wrangle the
patches into place.
If you need to create a L*a*b* image...I don't _think_ Argyll directly
supports that, though you might be able to do so with cctiff. But you can
certainly do so programmatically with ImageMagick.
Cheers,
