DrawingRelations

Manages drawing relationships and external linkage information.

Responsibilities:

  • Relationship ID allocation for drawings and VML objects
  • Tracking drawing and VML relationship mappings
  • Managing external links for drawings, comments, tables, and media
  • Providing relationship data for rels file generation

This module handles how drawing resources are linked together. It does not prepare drawing objects or write XML output.

Get the index used to address a drawing rel link.
