eer format, avoid warning.

See original GitHub issue

Hi! First, congratulations for this package. It seems flexible and very useful.

There is a new file format in the Cryo electron microscopy called eer. Is a Bigtiff file with some, at least specific compression.

I’ve tried this library and it gets the pages and size properly and wants about the COMPRESSION:

TiffTag 259: 65001 is not a valid COMPRESSION

For me, so far, I’m ok with this behaviour, do not actually need to read the images but know its dimensions.

Is there a way to avoid the warning?

I see this could be the right package to read these files. What would be the procedure in case you agree to read eer?

I asked this in their repo recently:

The only one I see in this folder is here: (ending with .eer)

In EMPIAR (public repository for electron microscopy data) there are a few entries:

Many thanks for the fast reaction!

Which licence will allow the addition of the compression code to tifffile/imagecodecs?

There is a chance they can change the license. At least I’ll ask them.
