我使用的是iTextSharp版本4.1.2并且无法更新到更新的版本，因为iText更改了他们的许可协议。 我对这个版本非常满意，它对我来说很好。

I am using iTextSharp version 4.1.2 and cannot update to newer version because iText changed their licence agreement. I am very satisfied with this version and it's working fine for me.

我找不到任何地方如何制作饼图或条形图或柱形图和图表使用该版本的看起来像互联网上的所有文档都被删除了。 如果您使用的是旧版本，并且您有机会获得文档，请分享或指向我的来源，或解释如何？

I can't find anywhere how to produce pie or bar or columns graphs and charts with that version and looks like all documentation over the internet been removed. If you are using older version and by the chance you have documentation can you please share or point me to the source, or explain how?

推荐答案

iText没有内置的图表或图形支持。相反，我们鼓励您使用第三方库生成这些库，然后将它们添加为图形或PDF。

iText doesn't have built-in support for charts or graphs. Instead you are encouraged to use a 3rd-party library to generate these and then add them as either graphics or PDFs.

这篇文章是使用 iTextSharpExtensions 。请注意，虽然它中有iText字样，但并不是iText制造商认可的。

Another option as outlined in this post is to use the iTextSharpExtensions. Please note that although it has the word "iText" in it is in no way endorsed by the makers of iText.

另外，作为一个快速的注释，请阅读常见问题解答，特别是为什么我不应该使用iText 2.x（或iTextSharp 4.x ）？解释你正在使用的版本的许可证的一些神话。

Also, as a quick side note, please read FAQ, specifically the "Why shouldn't I use iText 2.x (or iTextSharp 4.x)?" explaining some of the myths of the license of the version you are using.
