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

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,
