Open Microscopy Environment

One thing that has never been clear to me, and I can't find good information on the trac either: How is it with server-side compression? In particular, does omero do lossless compression and what type? (answers what compression rate can be expected for different types of images) Is it possible to apply lossy compression on selected datasets?

Hi,
There is no lossless compression in OMERO. When an image plane is rendered, OMERO reads the uncompressed data from disk, applys rendering settings etc and generates a compressed image that is then displayed in the clients. The level of compression can be set in the clients (E.g. when you log in to Insight) but this compression is for viewing only (not storage).

Does that answer your question?
