Hi,
I am not sure to understand what are you trying to do...
You have created a ICC profile and what to read the
different components from the profile?
You are trying to create a profile?
You are trying to apply a profile?
Regarding white point, not all white points fall into
blackbody locus, so, you can create a white point
from a temperature, but not all white points are
associated to a temperature.This is not a 1:1
relationship.
Regards,
Marti.

Subject: [Lcms-user] How to retrieve data in rgb file
Hi,
To create an RGB Profile I'm Giving some parameters.
The WhitePoint (it's the value in Kelvin translated
by the function cmsWhitePointFromTemp)
The primaries (red, green and blue parameters)
The transfer function (a gamma curve)
Now I try to read my icm file.
I know how to read the type of file.
I'm calling the cmsGetColorSpace function. If the
returned value is icSigRgbData the file is a RGB
profile file.
I know how to read the white point
(cmsTakeMediaWhitePoint) but I don't know how to
convert the white point in temperature (the inverse of
cmsTakeMediaWhitePoint).
I try to read the Primaries and the Transfer function.
Can you help me ?
Thanks
