Parameters

BookmarkID: A unique bookmark identifier specifying a required bookmark object.
You can obtain this identifier using these methods: GdPicturePDF.NewBookmark, GdPicturePDF.GetBookmarkRootID, GdPicturePDF.GetBookmarkFirstChildID, GdPicturePDF.GetBookmarkNextID or GdPicturePDF.GetBookmarkPrevID.

Return Value

A unique bookmark identifier of the parent bookmark item for the specified bookmark. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.

This method is only allowed for use with non-encrypted documents.

It is recommend to use the GdPicturePDF.GetStat method to identify the specific reason for the method's failure, if any. For example, if the specified bookmark item has no parent bookmark item, the value of GdPictureStatus.InvalidParameter is returned.
