Loading PDF from Stream Freezes Indefinately

[danielscoggins]

Hi,

Using aspnet web, the attached file is uploaded, file is copied to System.IO.MemoryStream.
When new PdfDocument(MemoryStream) is executed, it hangs indefinitely. It should crash, the first page is corrupt (bad xref).

Attached is a sample PDF.

Code: Select all

using (var ms = new MemoryStream())
{
    Request.Files[0].InputStream.CopyTo(ms);
    ms.Flush();
    ms.Seek(0,SeekOrigin.Begin);
    using(var pdf = new PdfDocument(ms)){
        //do stuff with the PdfDocument
    }
}

Hello,

Thank you for your inquiry.
I did not find your sample PDF in this post, hence I simulated a PDF file and tested it with the code you provided, but did not reproduce your problem. The version I used is the latest Spire.PDF(Spire.PDF Pack(Hot Fix) Version:7.7.10 ). If you were not using the latest version, please first give it a try. If the issue still exists after trying, please provide your sample PDF file again for our further investigation. You could attach it here or send to us via email ([email protected]). Thanks in advance.

Sincerely,
Annika

Hi Annika,

We are on 7.5.0. but I also tried 7.7.10 and 7.8.2. the behavior across each version is the same.

I couldn't upload the file, I've emailed it to support.

Thanks,
Daniel
