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 XYCutStrategy (recursive spatial partitioning).
