HTML到PDF-使用PdfSharp和HtmlRenderer进行分页

问题描述

我尝试使用PdfSharp和HtmlRenderer将HTML转换为PDF.这是代码的一部分:

I try to convert HTML to PDF using PdfSharp and HtmlRenderer. This is part of code:

private byte[] CreateHtmlContent()
{
    string htmlContent = File.ReadAllText(@"htmlExample.txt");

    using (MemoryStream ms = new MemoryStream())
    {
        PdfDocument pdfDocument = new PdfDocument();
        PdfDocument pdf = PdfGenerator.GeneratePdf(htmlContent, PdfSharp.PageSize.A4, 60);
        pdf.Save(ms);
        res = ms.ToArray();
    }
    return res;
}

除分页符外，一切都正常.在某些页面上，我得到的结果类似于此图片

Everything works fine except page break. On some pages I have result like on this image

是否可以解决此问题? HTML内容是简单的html，仅包含标题和段落，没有其他标签.我在iTextSharp上没有这个问题，但是在这个项目上，我必须使用PdfSharp和MigraDoc.

Is it possible to fix this? HTML content is simple html that contains only headings and paragraphs and no other tags. I had no this problem with iTextSharp but on this project I have to use PdfSharp and MigraDoc.

您可以设置custom-css-property

You can set the custom-css-property

td { page-break-inside: avoid; }

在您要控制分页符的所有元素或选择器(td，p，.my-class等)上

on all elements or selectors you want (td, p, .my-class, etc.) to control the page breaking.

如果希望库控制某些元素的分页，则可以使用值"auto"

You can use the value "auto" if you want the library to control your page breaking on certain elements

td { page-break-inside: auto; }

还有一个在运行的文本中分页的示例.

There is also a example for page breaking in running text.
