2003.02.20 06:14 "How is alpha handled within tiff Lab?", by Kai-Uwe Behrmann
I ask this because I get some errors with some applications. All I want to do is convert RGBA to Lab(a). Is Lab-alpha the normal alpha channel (premultiplied/unassociated) in tiff-6.0?
Any hints would be welcome.
PS: I have not seen any Lab examples yet. Is there a test suite on the web?
