I have some input CLUT profiles that use LAB as PCS. Do you know any
utility that will convert that to XYZ PCS?
Yes, but probably not the way you were thinking of doing it
(ie. rewriting the clut table values and then changing the
PCS in the header).
A complication would be any per channel output
curves - not so easy to just convert the values for those,
since the input domain would have to change !
Using my toolset I could re-create the profile by making
a synthetic "chart" data set from the existing profile,
and then make one in the opposite PCS. You would loose
accuracy in the process.
But of course it would help a lot to know WHY you want
to do such a thing ?
