Detecting a Corrupt PDF

Aspose.PDF Product Family
1

Hi Team,


We are using 9.7.0.0 verion of Aspose.Pdf for all kinds of PDF operations. I am facing a problem in detecting a corrupted PDF file. Aspose.Pdf .Document class successfully loads a corrupt PDF and even provides the Page Count accurately.

My requirement is to determine if PDF is corrupt and if it is corrupt, I don’t want to go ahead with the processing. Is there any way to detect a corrupt PDF file using Aspose.Pdf ? I searched the Aspose.Pdf forum but couldn’t find anything positive for this.

I have also attached one corrupt PDF file, which I created by opening the PDF file in notepad and deleting some content. Kindly suggest.

Regards,
Anto Paul Thekkan

Hi Anto Paul,


Thanks for contacting support and sorry for the delayed response.

I have tested the scenario and have managed to notice that page count of 10 is being returned when suing following code snippet. However when viewing the document in Adobe Reader 11.0, an error message is being displayed. For the sake of correction, I have logged this problem as PDFNEWNET-39630 in our issue tracking system. We will further look into the details of this problem and will keep you updated on the status of correction. Please be patient and spare us little time. We are sorry for this inconvenience.

[C#]

Document document = new Document(“c:/pdftest/CORRUPTED.pdf”);

Console.WriteLine(document.Pages.Count);

During my testing, I used the latest release of API and managed to reproduce it. Also please note that fix for this problem will be included in future releases of Aspose.Pdf for .NET and I am afraid we might not be able to fix the issue in previous release versions.
