⚡ RasgaPDF

🚀 Why RasgaPDF?

Most Python PDF extraction libraries make fragile guesses: they flatten multi-column layouts into corrupted text streams, mangle tables, and strip away 2D positional geometry.

RasgaPDF does one thing with uncompromising precision:
It returns the exact 2D physical spatial geometry of the PDF directly to Python:

• Exact Bounding Boxes: Every character, word span, line, block, and table has exact coordinates [x0, y0, x1, y1].
• Zero Lossy Heuristics: No broken markdown assumptions. Downstream LLMs, RAG pipelines, or vision-language models receive the true physical layout.
• Pure Native Speed: Powered by a SIMD-parallelized Rust core. Extracts typical pages in ~3 to 8 ms.
• Self-Contained Wheel: Pre-compiled native binaries bundled directly in the wheel. Zero external runtime dependencies.

⚡ Quick Benchmarks (Python)

Measured on Intel Core i7-1365U (Single-thread latency, 1-page complex PDF):

📦 Installation

pip install --upgrade rasgapdf

💡 Usage

RasgaPDF offers two distinct modes for Python engineers:

⚡ Mode 1: Raw Physical Coordinates (parse_raw)

The fastest and most direct extraction possible. Returns a flat list of physical 2D coordinates for every text span on the page, with zero block/table overhead (~3-8 ms):

import rasgapdf

# Parse raw physical coordinates
doc = rasgapdf.parse_raw("document.pdf")

print(f"Extracted {doc['total_spans']} spans in {doc['parse_time_ms']:.2f} ms")

for span in doc["spans"]:
    print(
        f"[Page {span['page']}] "
        f"bbox=({span['x0']:.2f}, {span['y0']:.2f}, {span['x1']:.2f}, {span['y1']:.2f}) "
        f"font={span['font_name']} ({span['font_size']}pt) "
        f"text=\"{span['text']}\""
    )

Output Structure:

{
  "file_name": "document.pdf",
  "total_pages": 1,
  "total_spans": 20,
  "parse_time_ms": 7.78,
  "spans": [
    {
      "page": 1,
      "x0": 50.0,
      "y0": 67.0,
      "x1": 244.0,
      "y1": 83.0,
      "font_size": 12.0,
      "font_name": "Helvetica",
      "text": "The Future of Artificial Intelligence"
    }
  ]
}

🎯 Mode 2: Hierarchical Structured Document (parse_pdf)

Parses the visual hierarchy: paragraphs (text_blocks), text lines (lines), spans, and auto-detects matrix tables via column alignment:

import rasgapdf

doc = rasgapdf.parse_pdf("invoice.pdf", detect_tables=True)

for page in doc["pages"]:
    print(f"--- Page {page['page_number']} ({page['width']}x{page['height']} pt) ---")
    
    # 1. Inspect Text Blocks
    for block in page["text_blocks"]:
        print(f"Block #{block['block_id']} at {block['bbox']}:")
        for line in block["lines"]:
            print(f"  Line: {line['text']}")

    # 2. Inspect Detected Tables
    for table in page["tables"]:
        print(f"Table ({table['col_count']} cols x {table['row_count']} rows):")
        print("Headers:", table["headers"])
        for row in table["rows"]:
            print("Row:", row)
