我们无法更改从以下代码生成的pdf的字体大小,有人可以帮助我们吗?

我们希望在更改字体大小后将该 html 文件转换为 pdf。

using iTextSharp.text;
using iTextSharp.text.html.simpleparser;
using iTextSharp.text.pdf;
protected void ConvertToPDFNow()
{
 StringWriter sw = new StringWriter();
    HtmlTextWriter w = new HtmlTextWriter(sw);
        print.RenderControl(w);
         string htmWrite = sw.GetStringBuilder().ToString();
   Response.ContentType = "application/pdf";

    Response.AddHeader("content-disposition", "attachment;filename=FileName.pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    htmWrite = Regex.Replace(htmWrite, "</?(a|A).*?>", "");
    htmWrite = htmWrite.Replace("'r'n", "");
    StringReader reader = new StringReader(htmWrite);
    Document doc = new Document(PageSize.A4);
    //Creating Document of A4 Size
    HTMLWorker parser = new HTMLWorker(doc);
    PdfWriter.GetInstance(doc, Response.OutputStream);
    doc.Open();
    try
    {
    //rendering Html File                
   parser.Parse(reader);
    }
    catch (Exception ex)
    {                   
    }
    finally
    {
        doc.Close();
    }
   }

如何使用iTextSharp更改Pdf文档的字体大小

尝试应用样式表:

...
    var style = new StyleSheet();
    style.LoadTagStyle("body", "size", "12px");
    parser.SetStyleSheet(style);
...

下面的C#代码可以很好地改变itextpdf字体大小:

var style = new StyleSheet();
style.LoadTagStyle("body", "size", "8px");
HTMLWorker htmlworker = new HTMLWorker(document);
htmlworker.SetStyleSheet(style);
