Version requirement?

[jseabold]

Do you know the version requirements for lcms? I seem to be running into some API changes in version 2.5 unless I have a bad install.

I am using lcms version 1.19. I will see if I can test it with newer version of lcms. Meanwhile, can you post your error messages?

It looks like lcms.cmsOpenProfileFromFile is gone and it's now just lcms.FileProfile. That's as far as I got making changes, because it looked obvious.
