jpx_source::access_meta_manager

Call this function any time after a successful call to open to gain access to the infrastructure used to manage metadata which is not directly related to image interpretation. See the description of jpx_meta_manager and (first) jpx_metanode to learn more about the management structure, and what metadata is actually managed.

Note that you are allowed to edit the metadata associated with an open JPX data source, although the edits will not automatically be reflected in the original source. Nevertheless, you can use jpx_meta_manager::copy to copy an edited collection of metadata to a new file managed by jpx_target.

Note also that the interface returned via the present function ceases to be valid once close is called.
