Is there an option to extract a list or count of links, bookmarks, or annotations from a document without iterating through each page? For a file with more than 20,000 links and bookmarks, this can cause memory issues, throw exceptions, or be very slow.

Can you please share such document or any sample PDF file for our reference so that we can test the scenario in our environment and address it accordingly.

I am working with a document that is for restricted use, and I need to obtain permission before sharing it. Meanwhile, I would like to understand if there is any method or option available in Aspose.PDF to get a list or count of links, bookmarks, or annotations without iterating through each page.

Currently, I am using the following code to iterate through each page and extract the required information:

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(FileAbsolutePath);

PageCollection psd = pdfDocument.Pages;
AnnotationCollection annots = null;
int iTotalPages = psd.Count;

foreach (Page pageDic in psd)
{
    int page = pageDic.Number;
    string sourcePage = page.ToString();
    annots = pageDic.Annotations;
    for (int index = 1; index <= annots.Count; index++)
    {
        Annotation annot = annots[index];
        string Aname = annot.GetType().Name;

        if (Aname.Equals("LinkAnnotation"))
        {
            LinkProperties = ProcessPageLinkInfo(annot as LinkAnnotation, page, filepath, FileName, folder, pageDic, iTotalPages, DestinationFileNamedDestinations, pdfDocument, qcsettings);
        }
    }
    pageDic.Dispose();
    if (page % 500 == 0)
    {
        GC.Collect();
        GC.WaitForPendingFinalizers();
    }
}

We need to extract properties such as:

  • SourcePage
  • DestinationPage
  • Title
  • Action
  • RelativePath
  • NamedDestination
  • Openin
  • Magnification
  • LinkTextColor
  • Rectangle
  • Dimensions
  • Highlight
  • LineColor
  • LineStyle
  • LineThickness
  • TotalPageNumber
  • BookmarkLevelInNumber

Is there a more efficient way to achieve this without iterating through each page? Any guidance or suggestions would be greatly appreciated.
