AI Summary
This release adds font weight metadata to text items and improves text rendering by excluding off-canvas labels. It also fixes PDF loading to tolerate leading bytes and introduces an opt-in feature to infer boldness from font weights.
Key Highlights
- Added `font_weight` metadata (100..=900) to text items across Rust, Node, Python, and CLI tools.
- Added opt-in `bold_from_weight` API to infer boldness from font weights (600 or higher).
- Fixed text clipping to exclude labels painted wholly outside their rectangular bounds.
- Improved PDF loading to tolerate leading bytes before the standard `%PDF-` header.
Breaking Changes
- Rust migration: `TextItem` literals now require `font_weight: None` for items with unknown weight classes.
New Features
- Font weight metadata support for text items.
- Opt-in `bold_from_weight` inference for positioned-text and region APIs.
- Enhanced PDF header detection within the first 1024 bytes.
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)
