Dapatkan Metadata PDF

Dokumen PDF sering kali berisi metadata berharga yang menggambarkan konten dokumen, kepengarangan, dan izin. Aspose.PDF menyediakan API yang mudah digunakan untuk mengambil properti metadata standar maupun khusus. Potongan kode ini menunjukkan cara menggunakan the PdfFileInfo kelas untuk memeriksa file PDF secara programatis, termasuk contoh langkah demi langkah dalam Python.

1. Muat file PDF.
2. Ambil metadata standar.
3. Periksa status PDF dan keamanan.
4. Ambil metadata khusus.

from config import set_license, initialize_data_dir


def get_pdf_metadata(infile):

    # Get and display PDF information
    pdf_info = pdf_facades.PdfFileInfo(infile)
    print(f"Subject: {pdf_info.subject}")
    print(f"Title: {pdf_info.title}")
    print(f"Keywords: {pdf_info.keywords}")
    print(f"Creator: {pdf_info.creator}")
    print(f"Creation Date: {pdf_info.creation_date}")
    print(f"Modification Date: {pdf_info.mod_date}")

    # Check PDF status
    print(f"Is Valid PDF: {pdf_info.is_pdf_file}")
    print(f"Is Encrypted: {pdf_info.is_encrypted}")
    print(f"Has Open Password: {pdf_info.has_open_password}")
    print(f"Has Edit Password: {pdf_info.has_edit_password}")
    print(f"Is Portfolio: {pdf_info.has_collection}")

    # Retrieve and display a specific custom attribute
    reviewer = pdf_info.get_meta_info("Reviewer")
    print(f"Reviewer: {reviewer if reviewer else 'No Reviewer metadata found.'}")
