I am looking to programmatically set the copyright metadata in a bunch of PDF's without using Adobe Acrobat. Is there a free way to do this? (iText7, PDFSharp)
I tried iText7(AGPL) in VB.NET:
Dim pdfDoc As PdfDocument = New PdfDocument(New PdfReader(FN))
Dim catalog As PdfDictionary = pdfDoc.GetTrailer()
Dim map As PdfDictionary = catalog.GetAsDictionary(PdfName.Info)
And the map key-pairs did not have copyright info. Is there a way to do this?
