java - 如何在使用 itext 从 HTML 创建 pdf 时自定义字体样式

标签 java css itext

我正在使用 itext 库从 Html 文件创建 PDF 文件，但是在转换它时使用一些默认的 css 库并且没有创建所需格式的文件。有人可以建议我如何在使用 XMLWorkerHelper.MOSTLy 转换时自定义字体样式我需要在写入 PDF 时减小字符大小。

Below is my code.

I need all the td tags in the same line with out any break.

最佳答案

您的 HTML 看起来就像是由 Word 创建的。它包含很多不必要的东西。一些不必要的东西在 XML Worker 的上下文中也是不需要的，所以我不得不修剪掉阻止 iText 和 XML Worker 将 HTML 呈现为 PDF 的东西。

看看table11.html看看我对 HTML 做了什么。然后运行 ​​ParseHtmlTable11将 HTML 转换为 PDF。结果将是 html_table_11.pdf :

在此屏幕截图中，您可以在左侧看到在浏览器中呈现的原始 HTML，在右侧可以看到 iText/XML Worker 从该 HTML 创建的 PDF。我还打开了文档属性的字体选项卡，以显示 Calibri 和 Calibri-Bold 用作字体。
