#1 Warning - green gamma table not monotonic

[Jordi Cucurull Juan]

Dear Developers,

First of all let me thank you for being developed your application. I am trying to load my Windows ICC profile under my Debian Lenny. When I use the application, version 0.8, it loads the profile but shows this warning "green gamma table not monotonic" five times. I do not know which can be the problem, but the color presented in the screen I think is not correct after the profile load.

Thank you for your help,
Jordi.

Hi Jordi,

thanks for reporting. This message basically says that your profile contains data that does probably not make sense. If you could send me the ICC profile I will have a look, but I guess it's a problem with the profile.

Cheers

Hi Stefan,

I have attached my profile. I repeated the calibration and I tested the new profiles and I have the same issue.

Cheers,
Jordi.

non-monotonic green vcgt

Okay, I've seen the profile and uploaded a screenshot from my mac.
I'm a little puzzled why Logo (part of Gretag Macbeth - now X-Rite) allowed such strange curves - for pure green this would mean that there's really a non-monotonic behavior.

I'm considering removing this check with a commandline parameter, but see no need to entirely remove the check.

Stay tuned. I will have to release a new version soon anyway.
