I am creating a new Pdf from an existing Pdf ( original ) and add customized
pages on top of that Pdf. I am able at this moment to retrieve metadata from
Pdf by using: info = reader.getInfo(); However, when I want to get the value
for "Keywords" info.get("Keywords") it is returning null; When I go through
the map and look at the key-value pairs returned I do not see the key:
Keywords. However, the Pdf ( original ) has value for Keywords.
*Question*: How do I get the value for keywords which is present in the
metadata section of the original Pdf?
*Sample Code:*
// Step 2.5 Copying Pdf Properties.
reader = new PdfReader(secondFile);
HashMap<String, String> map = reader.getInfo();
String title = map.get("Title");
String author = map.get("Author");
String subject = map.get("Subject");
String keywords = map.get("Keywords"); ------------>
This one returns
null for the original Pdf.

<http://itext.2136553.n4.nabble.com/file/n4661008/Screenshot_%2830%29.png>
String creator = map.get("Creator");
if (title != null)
document.addTitle(title);
if (author != null)
document.addAuthor(author);
if (subject != null)
document.addSubject(subject);
if (keywords != null) {
document.addKeywords(map.get("Keywords"));
}
Any help will be appreciated.
Thanks.
