public class Document extends java.lang.Object implements DocListener, IAccessibleElement
A generic Document class.All kinds of Text-elements can be added to a
HTMLDocument
. TheDocument
signals all the listeners when an element has been added.Remark:
- Once a document is created you can add some meta information.
- You can also set the headers/footers.
- You have to open the document before you can write content.
- You can only write content (no more meta-formation!) once a document is opened.
- When you change the header/footer on a certain page, this will be effective starting on the next page.
- After closing the document, every listener (as well as its
OutputStream
) is closed too.
// creation of the document with a certain size and certain margins Document document = new Document(PageSize.A4, 50, 50, 50, 50); try { // creation of the different writers HtmlWriter.getInstance(document , System.out); PdfWriter.getInstance(document , new FileOutputStream("text.pdf")); // we add some meta information to the document document.addAuthor("Bruno Lowagie"); document.addSubject("This is the result of a Test."); // we open the document for writing document.open(); document.add(new Paragraph("Hello world")); } catch(DocumentException de) { System.err.println(de.getMessage()); } document.close();
