incorrect UUID of tiled image

[atarkowska]

Tiling images using bfconvert:

bfconvert /tmp/source.tif /tmp/test/prefix_X%xY%y_Z%z_T%t_C%c.ome.tiff -tilex 1024 -tiley 1024 -option ometiff.companion prefix.companion.ome

generate incorrect UUID

$ showinf /tmp/test/prefix_X5Y5_Z0_T0_C0.ome.tiff
...
Failure during the reader initialization

Hi @olatarkowska, I failed to reproduce the exception using the following command:

bfconvert /tmp/source.tif /tmp/test/prefix_X%xY%y_Z%z_T%t_C%c.ome.tiff -tilex 128 -tiley 128 -option ometiff.companion prefix.companion.ome

and /tmp/source.tif being either a single 512x152 plane containing two 512x512 planes. What are the dimensions of the source file?

Also, the usage of %x and %y patterns in the bfconvert command can be used to create basic TIFF files, one per tile. However, the current OME-TIFF specification does not support the distribution of tiles as separate TIFF files. Tiled images can be created according the TIFF specification and the TiffData element in the OME metadata can refer to the tiled plane using the TIFF IFD.
