我正在尝试从 html 内容创建一个 pdf 文件。然而，有一个问题阻止了它，那就是“字体大小太小：当\xc4\xb1单击\n hw.Parse(new StringReader(HTML));中的按钮时出现0错误” 线。
\n\n请帮助我 \xc4\xb1 如何解决这个问题。

iText[Sharp]HTMLWorker不支持CSS 绝对大小值，HTML 中至少有一行正在使用该值，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>
删除类似的样式font-size:xx-Large，你应该没问题。
如果您愿意使用新的 iText[Sharp] XML/HTML 解析器，则可以使用 CSS 绝对大小值 - XML Worker 版本 1.1.3.0 中类似这样：
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
);
}
