If you have a direct access to iText's PdfWriter
, you can use PdfPageEvent
interface. 如果您可以直接访问iText的
PdfWriter
,则可以使用PdfPageEvent
接口。 An example of how to create headers and footers via PdfPageEvent
can be found here: http://itextpdf.com/examples/iia.php?id=103 有关如何通过
PdfPageEvent
创建页眉和页脚的示例,请访问: http : PdfPageEvent
But if you want to add something like 'page X of Y' to your header or footer - you should use PdfStamper
instead. 但是如果你想在页眉或页脚中添加“Y页面X”之类的东西 - 你应该使用
PdfStamper
代替。 An example for it can be found here: http://itextpdf.com/examples/iia.php?id=118 可以在此处找到它的示例: http : //itextpdf.com/examples/iia.php?id = 118
