2003.02.20 21:05 "Re: How is alpha handled within tiff Lab?", by Chris Cox
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?
Use Photoshop 6 or 7.
