PyMuPDF에서 OCR 기능을 사용하려면 Tesseract의 언어 지원 데이터가 필요합니다. 이를 위해 다음 단계를 완료해야 합니다:

  1. Tesseract의 언어 지원 폴더 위치를 확인합니다:

    • Windows: C:/Program Files/Tesseract-OCR/tessdata

    • Unix 시스템: /usr/share/tesseract-ocr/4.00/tessdata

  2. 환경 변수 TESSDATA_PREFIX를 설정합니다:

    • Windows: setx TESSDATA_PREFIX “C:/Program Files/Tesseract-OCR/tessdata”

    • Unix 시스템: declare -x TESSDATA_PREFIX=/usr/share/tesseract-ocr/4.00/tessdata
