Hi,

I see..

You are trying to do a NEGATIVE profile, and well, this is not supported. It never
has been supported though, not in current revision, nor in anterior one.
Negative profiling is a totally different subject, and the metodology is completly
different. Perhaps the last profiler would give some approximate results,  but
this only because a fortunate coincidence. I'm pretty sure the current revision would
beat that by using positive 8-bit images.

Sorry, but negative profiling is a really advanced feature, and I don't plan to support
that, at least in inmediate future

Have you even tried to profile a positive final image? I mean not using raw format
at all. The quality you could obtain is good enough, even for professional usage.
Raw does need 16 bits since it comes on 1.0 gamma space. The profiler does
support 16 bits, but not the measurement tool. This is a limitation of Qt, not of the
lprof library. So, you would need to measure the values by hand to use this mode... .

Hello Mart�,

MM> Could I ask for IT8 measurement files to try the profiling by myself?

Ok. The reference file should be a R010315.

Yes some times CLUT based profiles had problems with very dark
patches. Why LCMS only reads 8 bit images? This is a problem when user
stores RAW data (16 bits linear).
