Struct StructureTreeStrategy

pub struct StructureTreeStrategy { /* private fields */ }

Expand description

Structure tree-based reading order strategy.

This is the PDF-spec-compliant approach for Tagged PDFs (ISO 32000-1:2008 Section 14.7). It uses the structure tree’s pre-order traversal to determine the logical reading order of marked content.

For spans without MCIDs or when no structure tree is available, it falls back to the GeometricStrategy (column-aware geometric analysis).
