StructureElements property

Returns the shared cached structure snapshot for the viewer's current page

Reads Pdf.StructureElementsForPage[PageNumber] so a view whose page differs from TPdf.PageNumber receives the correct snapshot

Multiple views, readable-content extraction, reflow, and validation reuse the same revision-aware page cache

The returned array is caller-owned and can be retained or modified without affecting the cache or document

• The property requires an active viewer and document
• Relevant edits invalidate the affected page snapshot automatically
• Use the underlying TPdf traversal methods when explicit resource budgets or streaming callbacks are required
