Re: [Lcms-user] Out of gamut treatment (linear double precision sRGB -> 8-bit sRGB)

[Wenzel J. <we...@cs...>]

right -- a good tonemapping algorithm (with all parameters suitably 
tweaked) will bring everything into the gamut, so this problem will 
never arise.

But depending on the algorithm and parameters, there may still be a need 
to deal gracefully with values that fall outside of the gamut. But 
perhaps this is just an odd use case for a ICC engine.
