Property Value
Nullable (boxed) ulong value.This property accesses the ObjectData Size Announced DataSet (7:90). The DataSet represents the overall size of the objectdata, expressed in bytes, not including tags, if that size is known when transfer commences.
Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.
Set accessor replaces the current tag value if the tag is present in the metadata tree, adds the tag if it was not present, or deletes the tag if a null value is passed.
See the IPTC - NAA Information Interchange Model ver. 4.1 specification for tag usage details.
