I got the CZI format document 1.1(2012) from our Zeiss support
specialist. He didn't mention any license or agreement limitation. I
tried several times to get an updated version from Zeiss website but
haven't heard from them yet. Also Zeiss website interface may have
changed, I went through several steps to create service ticket. And
didn't see any click-through agreement option.

In this 1.1 version document, I cannot find any word mention what I
cannot do. It only describes the format.

Sure, I can do it in configure.

Now this driver can read uncompressed, BGR24, BGR48, and fluorescence 
image in Gray8 and Gray16, at most three fluorescence channels though.


Best,
