我正在尝试从html内容创建一个pdf文件。然而，有一件事阻止它字体太小：0 错误当ı点击按钮时 hw.Parse（new StringReader（HTML））;线。
请帮助我如何解决这个问题。

iText [夏普] HTMLWorker不支持HTML中至少有一行正在使用的CSS absolute-size values，并导致异常：
<span id='Label3' style='color:Red;font-size:xx-Large;font-weight:bold;'>ECN NO:</span> <span id='Label48' style='font-size:x-Large;'>aaa</span>
删除font-size:xx-Large之类的样式，你应该没问题。
如果您愿意使用新的iText [Sharp] XML / HTML解析器，那么<strong>可以使用CSS绝对大小值 - 类似这样的工作与XML Worker版本1.1.3.0：< / p>
StringReader stringReader = new StringReader(@"
<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml'>
<head><title></title></head>
<body>
<span id='Label3' style='color:Red;font-size:XX-Large;font-weight:bold;'>ECN NO:</span>
<span id='Label48' style='font-size:X-Large;'>aaa</span>
</body></html>
");
using (Document document = new Document()) {
PdfWriter writer = PdfWriter.GetInstance(document, STREAM);
document.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(
writer, document, stringReader
);
}
答案 1 :(得分：0)
在某些情况下，我使用了 style =“ font-size：large;” 会导致错误。 将其更改为 style =“ font-size：18px;” 解决了该问题。
