[Lcms-user] sRGB <--> XYZ transforms

[Richard M. <Ric...@en...>]

Dear list members,
I'm confused with sRGB <--> XYZ transforms (yes, I've read the Annex B of
tutorial, and used cmsFLAGS_NOTPRECALC with INTENT_ABSOLUTE_COLORIMETRIC)
My observations are:
sRGB white point (255, 255, 255) is transformed into (30457, 32152, 35275=
)
XYZ color, and back-transformed to sRGB gray point (240, 248, 250).
Is there any way to prevent this, or am I performing a bad transform ?
Thank you in advance
