AI Summary
This release introduces font weight metadata and fixes for clipped text and PDF header detection.
Key Highlights
- Added `font_weight` (100..=900) to text items to classify font heaviness.
- Added an opt-in `bold_from_weight` feature to detect bold text based on weight values.
- Fixed text extraction to exclude text painted entirely outside its rectangular clip.
- Improved PDF header detection to tolerate leading bytes before the `%PDF-` header.
Breaking Changes
- Rust literals for `TextItem` must now include the `font_weight` field.
New Features
- Font weight metadata (100-900 scale).
- Opt-in `bold_from_weight` detection feature.
- Clipped text exclusion logic.
- Robust PDF header detection.
Full Release Notes
Changes since 1.20.0: - Add `font_weight`, the font's 100..=900 weight class, to text items in Rust, Node, Python and `pdf2md --items-json`, with an opt-in `bold_from_weight` on the positioned-text and region APIs that reads bold from a weight of 600 or more and keeps runs of different weight as separate items (#536). - Leave out text painted wholly outside its rectangular clip, so off-canvas labels no longer leak into the surrounding text (#539). - Tolerate leading bytes before the `%PDF-` header, locating it within the first 1024 bytes as mupdf, pdfium and poppler do (#538). `bold_from_weight` is opt-in; `is_bold` and item merging are unchanged by default. **Rust migration:** `TextItem` literals need `font_weight: None` for items whose weight class is unknown. Release preparation: #546. [Full changelog](https://github.com/firecrawl/pdf-inspector/compare/v1.20.0...v1.21.0)
