Klaus,
While you're about it, can you document how this works ?
Assume I have an image "gaudy.tiff" and a measure set "cesspon.ti3"
or a profile "cesspon.icc"
What are the commands one types to get the adapted mapping ? Which of
the A2B tables in the result profiles is it in ?
Is there a way to do this with just a profile (no measures) ?
