Hi,
I have noticed that the _cmsReadInputLUT() appends the Lab V2ToV4 matrix as
the last stage of the retrieved A2Bx pipeline and _cmsReadOutputLUT()
inserts the reverse Lab V4ToV2 matrix as the first stage of the retrieved
B2Ax pipeline.
Therefore, by calling these functions:
A2BxPipeline = _cmsReadInputLUT(…)
B2AxPipeline = _cmsReadOutputLUT(…)
the resulted pipelines’ stages look like:
A2BxPipeline = {InputCurve, A2BxCLUT, OutputCurve, V2ToV4}
B2AxPipeline = { V4ToV2, InputCurve, B2AxCLUT, OutputCurve}
Q1) So, can you please tell why are the V2ToV4 and V4ToV2 matrixes used ?
Q2) Would it be ok for me to remove these matrixes (as I need to process the
A2BxPipeline resulted Lab values), and combine the resulted A2Bx and B2Ax
pipelines in order to realize a transform’s pipeline ?
Thank you,
Claudiu.
