Thank you very much for your reply.
I did some quick tests with the code you provided but it seems I have not achieved any positive result in saving the pages with the provided color profile data.
The results were always GenericRGB for TIFF, JPG and PNG regardless of me also using some other ICC files.
dataWithContentsOfFile_ returns an objective-c class NSConcreteData with the data represented as b'…' in it, what I guess is right and what
Anyway, thanks again for your help.
