Hi guys,
I have three questions for (any of) you:
What happened to the "C" linking interface that is mentioned in the
documentation? I couldn't find any C-compatible export in the header files. Did
I miss something?
Since most programming languages do not have a "half" primitive, it is fair to
say that since most pixel arithmetics are done in 32-bit single precision
"float" space, the 16-bit half-precision storage is actually lossy? If so, are
there any studies on how (human- or machine-) perceptually lossy this is, in
practice, both for in-camera images and computer-generated ones?
Am I right to say that only half of the exponent field of the variable
precision number representation will ever be used since a valid channel pixel
value ranges from -1 to 1? If so, is that handled by the lossless compression
schemes?
I might be completely off with all of this, but theses are the questions that
stick after some reading of the documentation and the code.
Thanks!
Vincent
