AI Summary

Hardens the parser against malicious or malformed PDFs by implementing strict bounds on resource expansion, CID ranges, and decoding operations to prevent unbounded CPU or memory usage.

Key Highlights

  • Caps Form XObject expansion, CID `/W` ranges, and content-stream decode operations
  • Track the text line matrix in Form XObjects and honor spacing operators
  • Merge small-caps runs to prevent reading as extra table columns

New Features

  • Hardened parsing for security
  • Text line matrix tracking in Form XObjects

## Highlights

- Caps Form XObject expansion, CID `/W` ranges, Encoding/ToUnicode CMaps, content-stream decode, detector `Tj`/`TJ` lookback, and disjoint-rect clustering so crafted PDFs cannot force unbounded CPU or memory (#370, #372, #373, #375, #379, #380, #381).
- Form XObjects now track the text line matrix and honor `T*` / `TL` / `'` / `"` / `Tc` / `Tw`, so nested form text keeps the right spacing (#369).
- Small-caps runs merge instead of being read as extra table columns (#371).

## Changes since 1.14.1

Source: [`f4aab3b...4bee4f9`](https://github.com/firecrawl/pdf-inspector/compare/f4aab3b...4bee4f9)

### Resource bounds
- Bound Form XObject expansion per page (#370)
- Bound CID `/W` range expansion (#372)
- Cap content-stream decode before allocating operators (#373)
- Bound Encoding CMap `cidrange` expansion (#375)
- Bound ToUnicode `bfrange` expansion during subset remap (#379)
- Bound detector `Tj`/`TJ` operand lookback to the previous operator (#380)
- Bound disjoint-rect table clustering so overlap tests stay subquadratic (#381)

### Extraction quality
- Track the text line matrix and handle `T*` / `TL` / `'` / `"` / `Tc` / `Tw` in Form XObjects (#369)
- Merge small-caps runs so they stop reading as table columns (#371)
