下面的示例演示了如何使用iText库设置各种属性，如作者姓名、创建日期、创建者姓名或者 pdf 文件的简单标题。

Document document = new Document();
try
{
	PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream('SetAttributeExample.pdf'));
	document.open();
	document.add(new Paragraph('Some content here'));
	//Set attributes here
	document.addAuthor('Jamez Gupta');
	document.addCreationDate();
	document.addCreator('onitroad.com');
	document.addTitle('Set Attribute Example');
	document.addSubject('An example to show how attributes can be added to pdf files.');
	document.close();
	writer.close();
} catch (Exception e)
{
	e.printStackTrace();
}
