Python GUI to generate TI1 files for ArgyllCMS and convert to i1profiler patch set

Really cool project. ArgyllCMS is super powerful but not exactly user friendly, so having a GUI bridge to i1profiler sounds perfect.

It might also be a good patch generator for a licensed i1Profiler user if a conditioning profile is NOT used but I haven't tested that theory.

I just wanted a GUI to scan in my patches with my new (to me) i1pro / efi es1000

Personally I think the ArgyllCMS patch generator is much more intelligent compared to the one by X-Rite i1Profiler. Especially the control of the amount of white/black patches and especially the amount of grey steps you can choose at will does indeed a better job in improving details in dark shadows. the i1Profiler patch generator is very rigid and you can only have a given amount of grey steps and given patch counts and the particular behaviour that sometimes choosing 1 extra patch removes all the grey and near neutral steps from the previous patch count. You would think that would add an extra grey step: unfortunately it is the opposite.

I noticed that... there was a thread on the luminous-landscape forum that details some "magic numbers" to follow for the number of patches in i1profiler. These magic numbers would be maximum neutrals and also a strict rgb grid, say 7x7x7 which is what i1profiler supposedly prefers and which is why i'm not sure that argyllcms patches would be better than the built in ones. I would probably need to run the same number of patches generated by argyllcms and i1profiler and for both, generate the profile in i1profiler to see which one is better.

Another thing in i1profiler is that it needs rgb values at the extremes 0-255. If not, i will simply barf while trying to make the profile. This is why you can't use a preconditioned ti1 files and expect a useable set of patches in i1profiler but It's perfectly fine to import in i1profiler to read them back and use them in argyllcms
