PDF Hebrew Text Decoder

This project provides tools to decode Hebrew text from specially encoded PDFs and process the extracted text for readability.

Installation

# Install dependencies
pip install pymupdf python-bidi

Key Components

• decode_pdf.py: Main script that extracts and decodes PDF text using character mapping
• process_pdf.py: Comprehensive script for PDF processing pipeline
• text_processor.py: Processes extracted text files with cleaning and RTL correction

Usage

Extracting and Decoding Pages

Edit decode_pdf.py to specify your input file and page range:

# At the bottom of decode_pdf.py
if __name__ == "__main__":
    pdf_path = "your_file.pdf"  # Change to your PDF file
    start_page = 0              # First page to process (0-based index)
    end_page = 10               # Last page to process (0-based index)
    output_dir = "extracted_pages"

    extract_and_decode_pdf_pages(pdf_path, start_page, end_page, output_dir)

Then run:

python decode_pdf.py

Full Processing Pipeline

Edit process_pdf.py to specify your input file:

# At the bottom of process_pdf.py
if __name__ == "__main__":
    pdf_path = "your_file.pdf"  # Change to your PDF file
    output_file = "final_text/full_processed_text.txt"
    
    process_pdf(pdf_path, output_file)

Then run:

python process_pdf.py

Workflow

1. Extract text from PDF files
2. Decode the text using Hebrew character mappings
3. Clean and process the text files
4. Output as readable text/markdown files
