Hi All,
I notice that the roadmap indicates that
LoadClut and Screen('Gamma') functions are not likely to be ready until January.
Just wondering how people are linearising their displays using OSX
I have found two commands within the documentation which would appear to be designed
for this purpose:
Screen('ReadNormalizedGammaTable')
and
Screen('LoadNormalizedGammaTable').
The latter function (as implemented below) successfully loads my lookup table,
but produces distorted luminance profiles.
%load linear CLUT
fid = fopen('linearisation_table','r');
linCLUT = fscanf(fid,'%d',[256 3]);
Screen('LoadNormalizedGammaTable', w, linCLUT/255);
I'd be grateful for any suggestions.
