Inner Exception 1:
ApplicationException: Reference table is not repaired

This is what I do:
var document = new Aspose.Pdf.Document(“test.pdf”);

I can reproduce this with version 18.10

Can you please explain why this is happening?

Has there been any update to this thread? I am seeing the exact same problem in my project when trying to save a document after adding images to pages.


Thank you for contacting support.

The ticket PDFNET-45631 has not been resolved yet. However, would you please create a separate topic while mentioning all the details where you may refer to this topic as well, so that we may investigate the scenario and take care of your concerns.

Has this been resolved yet?
I had this occur with a PDF that was generated BY Aspose PDF 17.4 (PDF version is 1.7). Unfortunately it is confidential so I cannot provide it.

Aspose.PDF will open the file but will not save it after optimization.

Interestingly PDFSharp is unable to open the PDF at all, although Acrobat, PDFium, and iTextSharp are totally fine with it.

My solution has been to use iTextSharp to re-save the PDF as version 1.4. After that, Aspose.PDF is able to handle the file fine.

We are sorry for the inconvenience.

Any chance this has been resolved? I am experiencing the same issue. I have attached a copy of one of the PDFs that is having the issue. I am currently using Aspose.Pdf .NET version TestDemo.pdf (47.4 KB)
