PDF中的PDF页面编号& iText的 [英] PDF Page Numbering in Java & iText

问题描述

我正在使用Java中的iText创建一些PDF报告。根据要求，我应该做的是以 page_number / page_numbers_in_total 的格式对页面进行编号。

I am creating some PDF reports using iText in Java. According to the requirements, what I should do is to number pages in the format of page_number/page_numbers_in_total.

但是，内存操作会给我的项目带来负担。因此，我不想再次浏览所有页面以便对它们进行编号。有没有办法实现呢？

However, memory operations burden my project. Hence, I don't want to go over all the pages again in order to number them. Is there any method to achieve that?

推荐答案

看看这个例子，它设置了一个类似的标题（Y页面X）：

Have a look at this example, which sets a similar header ("Page X of Y"):

你会看到 onEndPage 方法打印Page X of和 onCloseDocument 方法通过PdfTemplate在所有页面上设置Y。

You'll see that the onEndPage method prints the "Page X of ", and the onCloseDocument method sets the "Y" on all the pages through a PdfTemplate.
