推荐答案

假设您使用 document.add（）添加流动内容，则必须确保定义底部边距足以容纳页脚。

Assuming that you are adding the flowing content using document.add(), you have to make sure that you define a bottom margin that is sufficiently large to accommodate the footer.

您不能共享 OnEndPage 方法，但假设你有类似的东西：

You don't share the code you have in your OnEndPage method, but suppose that you have something like:

canvas.MoveTo(36, 50);
canvas.LineTo(559, 50);
canvas.Strike();

这从 x = 36 中划出一条线至 x = 559 at y = 50 。

This draws a line from x = 36 to x = 559 at y = 50.

假设您已经创建了文档，如下所示：

Suppose you have created your Document like this:

Document document = new Document();

在这种情况下，您创建的文档包含A4格式的页面（595 x 842用户单位） ）和36个用户单位的边距。由于底部边距仅为36个用户单位，因此您的内容可能与从底部以50个用户单位绘制的线重叠。

In this case, you are creating a document with pages in the A4 format (595 x 842 user units) and margins of 36 user units. As the bottom margin is only 36 user units, your content risks overlapping with the line drawn at 50 user units from the bottom.

您应该更改创建文档，如下所示：

You should change the line where you create the Document like this:

Document document = new Document(PageSize.A4, 36, 36, 36, 55);

现在您的下限为55个用户单位，而您在50个用户单位下划线不再重叠。

Now you have a bottom margin of 55 user units and the line you draw at 50 user units no longer overlaps.

注意：我使用术语用户单位，因为这是我们在PDF中定义测量的方式。默认情况下，1个用户单位等于1个点。默认保证金为36个用户单位或半英寸。

Note: I use the term user units because that's how we define measurements in PDF. By default 1 user unit equals 1 point. The default margin is 36 user units or half an inch.
