Splitting PDF in individual pages breaks the iterator

Aspose.PDF Product Family
1

The following code throws a null reference exception after two pages:


var pageNr = 1;
var pdfDocument = new Document(GetFilePath(fileName));

foreach (Page page in pdfDocument.Pages)
{
using (var pageDocument = new Document())
{
pageDocument.Pages.Add(page);
pageDocument.Save(GetFilePath(fileName + “-page-” + pageNr));
}
pageNr++;
}

After two iterations the page object is null. Works for any PDF I tested.
If I remove the save action, the iteration works fine.

I already found an alternative in PdfFileEditor.Extract, but this code whould work anyway.

Hi,


Thanks for using our API’s.

I have tested the scenario using Aspose.Pdf for .NET 11.9.0 where I have used some of sample PDF files and I am unable to notice any issue. As per my observations, the PDF files are properly being split into individual page documents.

Can you please share your resource/input files, so that we can test the scenario in our environment. We are sorry for this inconvenience.

Hi Viral,


Thanks for contacting support.

I have tested the scenario with one of my sample PDF’s and I was unable to notice any issue. The generated output(s) with throwing any exception. I have tested the whole scenario using Aspose.Pdf for .NET 17.3.0. We will really appreciate if you please provide a sample input file so that we can try to replicate the scenario in our environment.
