[Lcms-user] Transforming colors with A2B1 table

[Lorenzo R. <lo...@ma...>]

Hi,
I'm witting a code to obtain the gamut from an output RGB profile. I'm 
planning to use the A2B1 table (dev->pcs), as the gamut tag often is not 
a reliable source of gamut information. Looking at the littlecms API, I 
have two alternatives to scan the A2B1 table:
   1) create a transformation
   2) "navigate" in the profile LUTs.

To create a transformation using the RGB output profile as INPUT, in 
order to use the A2B1 table. Is it possible ?

If not, how can I scan the LUT ? It's only create a LUT from the A2B1 
tables using cmsReadICCLut ? I checked the profile and the only tags 
available are the A2Bx and B2Ax (x = 0, 1, 2) tables and there's no 1d LUTs.

Best regards,
Lorenzo
