Hello everyone!

First of all, thank you for efforts to develop and maintain this library!

I have a question about the versioning and hope someone can shed some light:

What is the relationship between this LibTiff and the LibTiff from Aperio (http://www.aperio.com/bigtiff/)?

It is very confusing because the version numbers and the release dates are pretty much the same.

Is the code the same and just the versioning different? Or is it a real "fork" with different code bases? Is the one from Aperio "newer" or has more features (because they are at version 4.1 and LibTiff at version 4.0)? Is there a reason to choose one library over the other?

I'm currently trying to understand an issue where I get BigTiff data which was generated by a version "4.1" of libtiff and I'm experiencing problems because of duplicated StripOffset tags, which prevents the file from working with ImageJ.

Would it be possible that the problem disappears when I switch to the "other" fork?

Thank you!

Bye,

Simon

PS: I updated some Wikipedia articles to mention the recent release of LibTiff 4.0, I hope this was ok.
