How to check whether the document uses PDF/A standard

Introduction


PDF/A is a special topic not much can be found about, so we have covered the creation of PDF/A documents our recent blog post. Sometimes you may need to check whether the PDF document already uses PDF/A standard, and we’ll show how you can get this done using Apitron PDF Kit for .NET component.

Code sample (C#)


static void Main(string[] args)
{
    using (Stream fileStream = File.Open("../../Data/document.pdf",FileMode.Open))
    {
        using (FixedDocument doc = new FixedDocument(fileStream))
        {
            // PdfStandard property can be used to check whether the document
            // uses PDFA standard. It will return PDfStandard.Default if the 
            // doc doesn't use PDFA or PdfStandard.PDFA if it does.
            Console.WriteLine(string.Format("Document uses '{0}'  standard",
 Enum.GetName(typeof(PdfStandard),doc.PdfStandard)));
        }
    }

    Console.ReadLine();
}


The output is shown below:
