Description

When producing an output OME-XML block, the OME-TIFF reader should inject a MetadataOnly element rather than using a BinData with Length="0".

(In [6978]) OMETiffReader now populates its' MetadataStore in such as way as to produce valid OME-XML (hopefully). BinData elements are not populated; instead, a MetadataOnly element is inserted under any Pixels that do not have at least one TiffData. See #556.

The only problem with this is that OMETiffReader.getMetadataStore() no longer returns a MetadataStore that can be used with an IFormatWriter (assuming, of course, that an IMetadata was passed to setMetadataStore). The current solution is a new OMETiffWriter API method: 'MetadataStore getMetadataStoreForConversion()'. This will return a MetadataStore of the same type as 'getMetadataStore()', but that contains the required BinData elements.

Status changed from new to closed
Resolution set to fixed

I'm fairly certain that this was fixed in r6978, but feel free to re-open if r6978's behavior does not match the expected behavior.

(In [7126]) Reversed usage of OMETiffReader's getMetadataStoreForDisplay() and getMetadataStoreForConversion(); getMetadataStore() is now equivalent to getMetadataStoreForConversion(). See #556.
