AI Summary

This release introduces selective OCR (Optical Character Recognition) for scanned and mixed PDFs, utilizing PDFium rendering and PP-OCRv6. It includes session reuse for performance and exposes the pipeline across multiple languages.

Key Highlights

  • Selective OCR for scanned pages and mixed PDFs using PDFium and PP-OCRv6.
  • Adaptive fusion of OCR results with native PDFium text layers.
  • OCR session reuse and row boundary preservation for faster extraction.
  • Exposed OCR pipeline with detailed provenance and timings in Rust, Python, Node.js, and pdf2md.

New Features

  • Selective OCR functionality.
  • Pinned runtime and model caching.
  • Offline operation support.
  • Rejoining hyphenated words across line breaks.
  • Improved handling of running headers, footers, and numbered reference notes.

## Highlights

- Adds selective OCR for scanned pages and mixed PDFs using PDFium rendering and PP-OCRv6 Small through ONNX Runtime (#348, #357, #358).
- Recovers credible PDFium text layers before OCR, routes only affected pages, and adaptively fuses OCR with usable native text (#359, #393, #394).
- Reuses OCR sessions and preserves row boundaries for faster, cleaner extraction (#390, #391).
- Exposes the OCR pipeline through Rust, `pdf2md`, Node.js, and Python, including page-level provenance, confidence, timings, warnings, and hosted-parser recommendations (#360, #403, #405).
- Adds pinned runtime and model caching, offline operation, and cross-language smoke coverage (#404, #409).

## Other improvements

- Rejoins words hyphenated across line breaks (#388).
- Improves running-header, running-footer, and numbered-reference-note handling (#374, #392).
