explore matrix white point handling #50

Closed beku closed 5 years ago

beku commented 5 years ago

create a abstract matrix variant to not clip HDR floats

enable shaper matrix profiles in lcm2
port the Bradford abstract profile code to bradfordMatrix
decide to remove Bradford abstract CIE*Lab LUT code as the code is mainly used internally by oyranos-monitor-white-point and related code
evaluate in compicc/ICC Examin
switch white point setup to CIE*XYZ matrix abstract profile generation

beku commented 5 years ago

Matrix profiles are enabled and bradford is ported to ICC PCS*XYZ based in the same algorithm like the previous table based abstract white point effect profile. Night mode in Compicc/oyranos-monitor-white-point looks the same. see commit bf77132e.

The matrix can be extracted and used for HDR content. This is not covered.
