Bio-Formats Exporter drops metadata for non-imported images

Description

The Bio-Formats Exporter does not preserve metadata when saving unless the image was opened with the Bio-Formats Importer. To reproduce:

  • File > Open Samples > Mitosis
  • Plugins > LOCI > Bio-Formats Exporter (e.g., save to OME-TIFF)
  • Close all open windows
  • Plugins > LOCI > Bio-Formats Importer (select the saved OME-TIFF)
  • The image calibration has been lost

The problem is that the Exporter propagates the IMetadata from the opened image if it is present (from the Importer), but if one does not exist it synthesizes a minimal one, excluding any metadata such as image calibration.

The fix is to populate any metadata available from ImageJ itself, particularly image calibration, and perhaps other information such as image labels.

(In [5786]) Ensure that calibration information is preserved, regardless of how the images were imported. Closes #458.
