| | 24 | 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. |

| | 26 | 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. |
