AI Summary

Hardens parsing for pathological PDFs by implementing bounds on Form XObjects, CID ranges, and content streams to prevent unbounded CPU or memory usage. It also improves the handling of Form XObject text line matrices.

Key Highlights

  • Caps Form XObject expansion per page
  • Bound CID `/W` range expansion
  • Cap content-stream decode before allocating operators
  • Track the text line matrix in Form XObjects
  • Merge small-caps runs to prevent table column misread

New Features

  • 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)
