Interesting that this didn't fail on getPlane() from a 'Big' image (same size as the one you're creating).

Is getPlane() supported for big images?

I'm not sure how to implement createImageFromNumpySeq() using tiles, since it currently takes a sequence of planes. It's possible that uploadPlane() could take a whole plane and upload it as tiles (solves the error above). This would possibly allow server-side scripts to use createImageFromNumpySeq() on big images (largish ones anyway) but this is not likely to be nice for remote clients.

To make the whole script tile-based would require a complete re-write and is not worth doing unless we know someone wants this functionality on big images.

Will, at the moment, getPlane is supported for big images, but will likely be removed in 4.3.1 (#4853). setPlane is completely disallowed. The intent is that all API consumers move away from plane-based methods towards tile-based ones. It may be worth modifying this as an example for others. Chris, thoughts?

(In [289e066f1beb547cf4a0247fb45617cfbe7fe38f/ome.git] on branch develop) Channel_Offsets.py handles Big Images with 'not supported' message. Closes #5716
