.net validation of pdfa file

问题

I try to write a validation method in a VB project to check if a PDF file is PDF/A. I was playing with itextsharp.pdfa but i don't find a way to validate this.

From here I understood that using itextsharp was not possible. Does itextsharp 5.5.5 include some functionalities like this?

Are there other dll I can use in a vb.net project for this validation?

回答1:

There currently is no such thing, but the European Union has mandated a project to build a "PDF/A Conformance Checker" as an open source project. You can follow the progress here: http://www.preforma-project.eu/pdfa-conformance-checker.html

Checking for PDF/A isn't trivial, so it will probably take a while before this project is finished. There has been a lot of discussion about this at the ISO meetings for PDF as well as by the PDF Association.

VeraPdf has been released some time ago and can be integrated using PdfAValidator

using (var pdfAValidator = new PdfAValidator.PdfAValidator())
     {
         var result = pdfAValidator.Validate(@"./TestPdfFiles/FromLibreOffice.pdf");
         Assert.True(result);
     }
