Found the bug. Not even sure how it even compiled. A new tarball (1.11.3.1) with the fixed (and tested) code is now on sourceforge. > > - After creating that directory manually, the "Create Profile" button was > greyed out sometimes. It would took a trip into "Profile Parameters" (not > changing anything) to make it come back and allow profile generation There might be a path through the code that misses the check to change the state of this button. What would help me is for you to describe the exact steps/conditions when this happens which might not be easy since it does not appear to happen in most cases. That would make it easier for me to reproduce and also give me some clues about were to look. I will also do some testing to see if I can find where this is happening. The new settings code affected how this works and I probably over looked something. > > - Trying to run through the resulting profile through "Profile checker" > aborted the program with: > > 32.719844 32.735409 32.377432 -> 11.670000 -0.720000 -0.170000 > 30.431907 30.571984 29.758755 -> 9.330000 -1.000000 0.320000 > 28.494163 28.505837 27.949416 -> 7.400000 -0.890000 -0.250000 > 26.202335 26.533074 26.750973 -> 4.770000 0.110000 -2.910000 > ************************************** > lcms: Error #12288; File '' not found Again like the above could you describe the exact sequence of steps you went through for this to occur. Does the Profile Checker dialog open? Does this error happen when you press the Inspect Profile button? If the dialog opens what values do you have for Profile: Target: and Measurement: ? And do these appear to be valid to you? > > I can provide version numbers of relevant libraries if necessary. > I don't think this has anything to do with specific version of libraries. As long as lcms is fairly recent. I have been testing with 1.14 and have tested with 1.13 in the past. But I have not tested yet with 1.15. > > On the plus side, it *did* generate a useable profile.

Great progress! > The new profiles should be way better than those created with the old non-local convergence algorithm in every respect. Larger gamut, much lower delta E numbers and smoother CLUT curves. These new profiles will have about the same gamut as the old local convergence algorithm but with slightly better delta E numbers and way smoother CLUT curves. Getting the CLUT curves smooth was the main point of the new algorithm but on the whole it has improved every aspect of these profiles. In addition it runs faster than the local convergence algorithm. At this point I personally believe that the new algorithm is generating profiles that are as good as anything out there even the multi-thousand dollar "professional" commercial profilers.
