    // Extract all images from the PDF document
    IEnumerable<Image> AllImages = PDF.ExtractAllImages();

    // Display the first extracted image in a PictureBox

    // Loop through each page of the PDF document
    for (var index = 0; index < PDF.PageCount; index++)
    {
        int PageNumber = index + 1;
