More digits for the whitepoint

[galinette]

Dear Indigo team,

I'm still working on having full color-proofness with Indigo for professionnal use in glass rendering.
Today, when I change the whitepoint in the GUI, the smallest fine tuning possible is 0.001, and this gives me a too big step in the final Lab colorspace values : I get a ΔE of around 2.0, which is too big. Especially, the D65 whitepoint is not a real D65, I think this is due to the rounding of the x and y values. The color differences are not huge, but perceivable on a calibrated pro monitor, and too big to pass color validation of the toolchain.

Two questions:
- If I set a whitepoint with more digits in the IGS code, will it be taken into account?
- Would it be possible to set more digits in the GUI? (4 would be better, 5 would give full precision).

Thanks,

Etienne

For some reasons I'm finding the captions cumbersome: they use comma and have a restricted input (besides precision. Numbers should shuffle to the right even though the firsts only will be retained).

+1, would be nice as UI options.

Hey galinette,

I'm not sure if that will work in the UI, probably not (settings in GUI are sent to the core every now and then). In console it should.

- Would it be possible to set more digits in the GUI? (4 would be better, 5 would give full precision).

Yes, thats very possible. It will be changed.
I can't promise that it will make it into the 2.6 stable (but also can't really see why it couldn't).

Cheers,
Yves
