|
## Installation
|
|
|
|
**Minimum Supported Rust Version (MSRV):** 1.78
|
|
|
|
### cargo
|
|
|
|
```bash
|
|
cargo install pdftract
|
|
```
|
|
|
|
### pip
|
|
|
|
```bash
|
|
pip install pdftract
|
|
```
|
|
|
|
### Docker
|
|
|
|
```bash
|
|
docker pull ronaldraygun/pdftract:latest
|
|
```
|
|
|
|
### Homebrew
|
|
|
|
```bash
|
|
brew install pdftract
|
|
```
|
|
|
|
## Quickstart
|
|
|
|
### Rust
|
|
|
|
```rust
|
|
use pdftract_core::{extract_pdf, ExtractionOptions};
|
|
|
|
let opts = ExtractionOptions::default();
|
|
let doc = extract_pdf("file.pdf", &opts)?;
|
|
println!("Extracted {} pages", doc.metadata.page_count);
|
|
```
|
|
|
|
### Python
|
|
|
|
```python
|
|
import pdftract
|
|
|
|
doc = pdftract.extract("file.pdf")
|
|
print(f"Extracted {doc['metadata']['page_count']} pages")
|
|
```
|
|
|
|
### CLI
|
|
|
|
```bash
|
|
pdftract extract file.pdf --json result.json # JSON output
|
|
pdftract extract file.pdf --text - # Plain text to stdout
|
|
pdftract serve --port 8080 # HTTP microservice
|
|
```
|
|
|
|
## What it does
|
|
|
|
- **Correct reading order** — layout regions are segmented and sequenced before text is emitted, handling multi-column pages, sidebars, footnotes, and mixed-layout documents
|
|
- **Font encoding recovery** — when `ToUnicode` CMaps are absent, wrong, or incomplete, pdftract works through a layered recovery pipeline: glyph name lookup, font fingerprinting, and glyph outline shape matching
|
|
- **Structure tree extraction** — PDF/UA and PDF/A documents encode their logical structure; pdftract reads this directly when present
|
|
- **Per-page hybrid routing** — each page is independently classified and routed to the appropriate pipeline: vector text extraction, full OCR, or assisted OCR
|
|
- **Structured output with provenance** — the primary output is JSON carrying per-span bounding boxes, font name, size, and confidence score
