Load and Save PDF failed


if i load the attached PDF with new Document(“Doc.pdf”) and save it, an error will be shown.
I can see that the PDF has a strange PDF/A conformance, maybe this is the problem.
Nevertheless the document should be saveable without errors.

Kind regards,

The issues you have found earlier (filed as PDFNET-53580) have been fixed in Aspose.PDF for .NET 23.6.


with the current Aspose.PDP version the problem still exists.
Its enough to load and save the PDF
Doc.pdf (189,0 KB)

with Aspose.Pdf.

AsposeDocument = new Aspose.Pdf.Document(InputPdf);

Kind Regards,

I checked on Windows 10, .Net 6 with version 23.11.1 package - there is no exception.
Please write in what environment you are running the code.
Does the application have normal access to ““c:_data\”?
