PDFtoPDFocr.spec

# -*- mode: python ; coding: utf-8 -*-
"""PyInstaller spec file for PDFtoPDFocr.

Optimized build to reduce size from 285MB to ~40-60MB:
- Excludes unnecessary packages (matplotlib, numpy, pandas, scipy, etc.)
- Uses onedir mode for faster startup in MSIX containers
- Bundles Tesseract portable + Poppler binaries via --add-data

Build:
    pyinstaller PDFtoPDFocr.spec

Prerequisites:
    1. Clean venv with only required packages:
       pip install PySide6 pytesseract Pillow pdf2image pikepdf requests
    2. tesseract_portable/ folder with Tesseract OCR binaries
    3. poppler/ folder with Poppler binaries (pdftoppm.exe etc.)
