thanks for reply Gerhard, appreciated!
actually I wanna get rid of the Pixel Shader part.
the script works wonderfully at this point, but there's only 2 media
players(MPC and KMPlayer) that support this sort of PS script.
I wanna get gamut conversion active in any video renderer(Haali's Renderer
particularly), so I need the gamut conversion to be done through the LUT.
there's many apps that are supposed to do ICC gamut mapping like icclink and
collink.exe......but I didn't succeed to get them working.
if I managed to do so, I could capture the LUT with Powerstrip and I'd be good
to go!
Ideally(and that's what a friend of mine is trying to do), the idea would be to
output 16bit LUT data from the XLS spreadsheet(considering the matlab coeffs
that it contains are very effective) then put them into the graphic card's LUT
with dispwin.exe ?!
or maybe some other app that can do gamut mapping ?
if it can be done through a simple 3x3 R/G/B matrix with a Pixel Shader, why
couldn't it be done through a 16 bit LUT ?! :(
