如何在c#中生成与HTML代码相同布局的动态PDF

本文关键字：代码 布局 PDF 动态 HTML | 更新日期: 2023-09-27 18:01:45

我正在动态地为一个目录生成HTML代码，我还想生成一个PDF。我考虑过只是将HTML页面打印成PDF文档，但是我失去了一些背景阴影和东西，并且它将内容拆分到各个页面。

我读了一些关于ittext的内容，但是我还没有弄清楚如何正确地格式化它，而且我不知道如何使它不会跨页面拆分我的内容。

这是我的HTML页面的开始，我包含了几个项目，所以你可以看到内容是如何分解的。我为丑陋的HTML道歉，我不能为我的生活让一个div表看起来正确!

<style type="text/css">
<!--
tr#odd {
    background-color:#e2e2e2;
    vertical-align:top;
}
tr#even {
    vertical-align:top;
}
div#title {
    font-size:16px;
    font-weight:bold;
}
div#mpaa {
    font-size:10px;
}
div#genre {
    font-size:12px;
    font-style:italic;
}
div#plot {
    height: 63px;
    font-size:12px;
    overflow:hidden;
}
-->
</style>

你可以在:http://timelessdesigncafe.com/movies/catalog.html看到它的样子注意，背景阴影是交替的。当我打印成PDF格式时，我失去了阴影，更重要的是，它在两页上吐出"行"/电影，我需要避免这种情况。

提前感谢!!

如何在c#中生成与HTML代码相同布局的动态PDF

没有人提到过wkhtmltopdf?:)

您可以使用OpenOffice API来完成此转换，在代码中执行以下步骤:

  • 加载OpenOffice API
  • 打开HTML文件
  • 保存为PDF

我知道它适用于VB(已经在VBScripts中使用过)，c++和Java，你应该能够用c#做同样的事情。

http://www.kalitech.fr/clients/doc/VB_APIOOo_en.htmlhttp://wiki.services.openoffice.org/wiki/API/Tutorials/PDF_export

你有很多方法可以做到这一点。请检查这个主题。如果你想使用免费的库或工具，你可以使用iTextSharp，但免费版本并不能满足所有的要求。你可以使用其他工具比如ABCPdf

正确布局HTML是一项非常重要的任务。我估计可能需要我一到两年的时间才能把它做好。

所以这不是我们要走的路。相反，您应该为数据过滤HTML，然后编写一个小型的专用PDF格式化程序，它可以完全满足您的需求，甚至可以在输入HTML中进行最小的更改。

那应该需要一周左右的时间。当你完成了这些，让它更适应输入HTML的变化。

如果你在使用WPF的位置，你可能要考虑使用FixedDocument和做你的布局在XAML打印。然后，您可以将XAML栅格化(如果合适的话，利用数据绑定)到XPS，即微软用于文档布局的XML Paper Standard(本质上是他们的PDF版本)。

这种方法的优点是能够利用数据绑定和XAML (IMHO)优于HTML的布局功能。我使用这个堆栈作为轻量级报告解决方案已经有一段时间了。(您需要在STA线程上生成报告)。

下一步(是的，这可能变得有点复杂)是将XPS流通过某些转换器转换为PDF格式，但不确定是否存在这样的事情。否则，您将依赖于您的客户拥有XPS阅读器(尽管这是内置在最新版本的Windows &办公室).

如果您不介意花一点钱，您可以投资于prinexml，它将任何Xml文档(包括XHtml)格式化为.pdf文档，并对Html内容应用完整的布局规则。事实上，Prince在布局时比许多浏览器更符合web标准:)

看一下WebToPDF。它是一个用c#编写的。NET组件，可以将HTML转换为PDF。您将得到一个pdf文件，看起来与HTML文件完全相同。我相信有能力指定页面大小，你可以用它来指定一个很长的页面，把所有的东西都放在一个页面上。

转换器支持HTML 4.01、XHTML 1.0、XHTML 1.1和CSS 2.1，包括分页符、表单和链接。它通过了所有W3C测试(BIDI除外)。
