The operation forms undo/redo data, sends correspondent events and modifies the document when the annotations were added on the Core level.


Name Type Description
Input Array Array of IUnknown-based objects containing the IPXC_Annotation objects that were inserted to the document on the Core level. Note that all of the annotations must belong to one document.
Output Array Array of IUnknown-based objects containing the IPXC_Document to which the annotations were added.
