How do I change/edit "Lang" entry in my PDF-s ?

[Support]

Q:

I would like to change/edit /Lang entry in my PDFs using Pdftron PDFNet. The Lang attribute can be found by using these lines :

 

         pdftron.PDF.PDFDoc oDoc = this.LoadPdfDoc(pdfFilePath);

          pdftron.SDF.DictIterator oLang = oDoc.GetRoot().Get("Lang");

         string lang = oLang.Value().GetAsPDFText();

 

But I am not sure how to change this attribute.

A:

You can update Lang attribute as follows:

 

doc.GetRoot().PutText("Lang", "Klingon");
