[argyllcms] Re: Snapshot V0.70 Beta 3 test now available.

Hi Grame,

first of all: many thanks for the new version. It must have been a huge amount of work to write the new drivers. Thanks!

I did not find the time to test the eye-one driver, but made some tests with profile an icclink (argyllV0.70Beta3_osx10.3_bin).

I found some strange discrepancies between the -kp parameters in icclink and profile:

I made two proflies:

profile -D"F39-test" -kp 0.0 0.2 0.9 1.0 0.6 -l320 -L98
     -S adobe_sRGB.icc -cmt -dpp FOGRA39

mv FOGRA39.icc F39-test-dev.icc

icclink -G -ip -cmt -dpp -kp 0.0 0.2 0.9 1.0 0.6 -l320 -L98
     adobe_sRGB.icc F39-test-dev.icc F39-test-lnk.icc

then I tested the results by converting a RGB gray ramp using cctiff:

cctiff -ip adobe_sRGB.icc -ip F39-test-dev.icc RGB-ramp.tif test-dev.tif

cctiff F39-test-lnk.icc RGB-ramp.tif test-link.tif

The separations look completely different, see attached plot "dev(thin)_vs_link(bold).pdf"

What's going wrong?

TIA, Klaus

BTW: is there no -D switch for icclink?
