Re: [Gimp-developer] OpenCL and GIMP tile size



Generally, downsampling should be done in linear light.
Not, however, upsampling.
If the samplers are standing in the way, I suggest that you let them eat
nonlinear light and implement the desirable conversion, which generally is
different for the up and downsampling components of the samplers, within
the sampler code.
(Emphasis on "suggest".)
Nohalo BTW does not convert. The upsampling component probably would look
better if it used nonlinear light.
