Support for large images?

OMERO's support for large images is slightly more complicated than it would appear. OMERO's pixel data interfaces are largely (up to and including OMERO Beta 4.1.x) planar. This means that the smallest unit of work is a 2D section of data; in OMERO nomenclature a "plane". This technique supports very large, multidimensional sets of data very well; up to many, many gigabytes in size.

Where this technique slightly falls down is where very large 2D sections are used. In the run up to the release of OMERO 4.2.0 we began addressing some of these issues which are referred to collectively by the team as "BigImages". We added support for such images in the 4.3.x series.
