我正在做一个 HTML to PDF 程序，我发现 nreco 是最好的。因为转换后的 pdf 包含正确的字体名称。不像我测试的那些。字体名称是随机字母。
这是我的转换代码。但问题是它不会像我的 html 中显示的那样在 PDF 中呈现图像。
public void HtmltoPdf(string[] htmlfiles, string outputLocation, float LeftMargin, float RightMargin, float TopMargin, float BottomMargin, float width, float height)
{
try
{
var htmlToPdf = new NReco.PdfGenerator.HtmlToPdfConverter();
htmlToPdf.Margins.Bottom = float.Parse((BottomMargin * 25.4).ToString());
htmlToPdf.Margins.Left = float.Parse((LeftMargin * 25.4).ToString());
htmlToPdf.Margins.Right = float.Parse((RightMargin * 25.4).ToString());
htmlToPdf.Margins.Top = float.Parse((TopMargin * 25.4).ToString()); ;
htmlToPdf.PageWidth = float.Parse((width * 25.4).ToString());
htmlToPdf.PageHeight = float.Parse((height * 25.4).ToString());
htmlToPdf.ExecutionTimeout = new TimeSpan(0, 0, 0, 5, 0);
htmlToPdf.GeneratePdfFromFiles(htmlfiles, null, outputLocation);
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
Debug.WriteLine(ex.StackTrace);
throw;
}
}
这就是我的示例 html 的样子
这是HTML代码
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

</div>
</div>
</div>
</body>
</html>
仅包含文本的其他页面的呈现与 html 非常相似。但是只有图像它会呈现一个空白页pdf。
我什至尝试在控制台上运行 WkHtmlToPdf
并且根本没有错误消息
我也试过itext pdf
byte[] pdf; // result will be here
var cssText = File.ReadAllText(@"\Styles\template.css");
var html = File.ReadAllText(@"\Text\d3e2793.html");
using (var memoryStream = new MemoryStream())
{
var document = new iTextSharp.text.Document(PageSize.A4, 50, 50, 60, 60);
var writer = PdfWriter.GetInstance(document, memoryStream);
document.Open();
using (var cssMemoryStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(cssText)))
{
using (var htmlMemoryStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(html)))
{
XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, htmlMemoryStream, cssMemoryStream, FontFactory.FontImp);
}
}
document.Close();
pdf = memoryStream.ToArray();
}
但是 itext pdf 的问题是字体名称与 html 中的字体名称不相似。例如，在我的 html 中，字体名称是“Adobe Caslon Pro”，但在我的 PDF 渲染输出中，字体名称是 Arial
这是CSS
