itext - 使用页眉和页脚 iTextSharp 创建多页 PDF
问题描述
大家好,提前感谢您的帮助。我需要开发一个应用程序来使用 iTextSharp 生成多页 PDF。每个页面都需要有页眉和页脚。此外,每个页面都会有各种不同的对象,包括表格、段落和类似于列表项的东西(可能是一个圆锥柱表)。我正在尝试找到一个教程来完成这个。我困惑的核心是如何确定何时应该发生中断,以及如果表格或段落太长而无法放在页面上,如何不覆盖页脚。任何帮助,将不胜感激。
我很欣赏 Bruno 的回应,并对 HTML 页面的样式以及使用 iText 进行渲染很感兴趣,但我真的很纠结如何在真实页面上实际执行此操作。这是我要打印的页面的一些示例 HTML:

我不确定如何实现 CSS 以确保页面内容不会覆盖页脚。此外,由于页面上的许多元素都是可以扩展的表格,您是否必须提前了解这些元素中有多少数据才能使用分页符?有人可以帮我开始吗?谢谢。
解决方案
使用 CSS 设置带有页眉、页脚和分页符的文档的示例:
页面设置
@page {
size: A4 portrait;
margin-left: 0.5cm;
margin-right: 0.5cm;
background: #FFF;
}
标头
@page {
@top-left {
margin: 10pt 0 10pt 10pt;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
}
@top-center {
margin: 10pt 10pt 10pt 0;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
}
@top-right {
margin: 10pt 10pt 10pt 0;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
}
}
页脚
@page {
@bottom-left {
margin: 10pt 0 10pt 10pt;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
}
@bottom-center {
margin: 10pt 10pt 10pt 0;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
}
@bottom-right {
margin: 10pt 10pt 10pt 0;
border-top: .25pt solid #666;
font-size: 9pt;
color: #FFF;
content: "Page " counter(page) " of " counter(pages); /* Add if you need page numbers */
}
}
分页符
在您的元素上使用page-break-before
、page-break-after
和page-break-inside
来设置适当的分页符。

Bruno Lowagie 更新
上面的答案是正确的,但不完整。它解释了如何在 HTML 中定义页眉和页脚,但没有解释如何使用这些页眉和页脚创建 PDF。幸运的是,这只需要一行代码。
请参阅HTML 到 PDF 教程。在第 2 章:定义样式和 CSS中,有一个名为“使用 @page 规则添加“Y 页 X”的部分,展示了该@page
规则如何与 iText 7 的 pdfHTML 插件结合使用。
您需要做的就是编写这行代码:
HtmlConverter.ConvertToPdf(src, dest);
wheresrc
是源(HTML 文件)和dest
目标(PDF 文件)。
