Q:
How can I access PDF document metadata such as document's author,
title, etc?
----
A:
The simplest way to access document's metadata (e.g. author, title,
keywords, etc.) is using PDFDocInfo class. For example,
Using C# or C++
PDFDocInfo info = mydoc.GetDocInfo();
String title = info.GetTitle();
info.SetTitle("My Title");
...
Using VB.NET:
Dim info as pdftron.PDF.PDFDocInfo = mydoc.GetDocInfo()
Dim title as String = info.GetTitle()
info.SetTitle("My Title")
...
