Description (last modified by rleigh)
This is a followup ticket for https://trac.openmicroscopy.org/ome/ticket/12596
While expanding the coverage of the C++ test cases, I've identified some additional variants which aren't properly handled.
Tile height greater than image height:

For the bit data, it looks like it's mainly restricted to chunky rather than planar data, though there are several hundred failing cases; I've just included a small selection here. The attached archive has a fairly comprehensive test set of many variants, which can be e.g. imported into OMERO in bulk to view.
For the bit data, I'm also not 100% sure if the samples here are correct. They might be, but I can't confirm it definitively without some other software capable of reading them, since the C++ unit tests only check if that the data round-trips and compares with a PNG reference image; it can't objectively test whether the packing is correct if it is writing and reading it using an incorrect assumption. All of the other software I tested with mishandles chunky bitmasks.
