为什么使用 iTextSharp 自定义 PDF 字体失败？

Question

我想通过加粗一些文本、使用不同的字体和颜色来装饰 PDF 文件中的各个段落。我以为我找到了如何执行此操作的代码（如下），但它不起作用 - 所有文本都是相同的字体、颜色（黑色）和大小。为什么我为美化 PDF 文件而费尽心思的努力至今都白费了？这是我的代码：

using (var ms = new MemoryStream())
{

    using (var doc = new Document(PageSize.A4, 50, 50, 25, 25))
    {
        using (var writer = PdfWriter.GetInstance(doc, ms))
        {
            doc.Open();

            // Mimic the appearance of Duckbill_Platypus.pdf
            var docTitle = new Paragraph("Duckbilled Platypi - they're not what's for dinner");
            var titleFont = FontFactory.GetFont("Courier", 18, BaseColor.BLACK);
            docTitle.Font = titleFont;
            doc.Add(docTitle);

            var subTitle = new Paragraph("Baby, infant, toddler, and perhaps 'Terrible 2s' Platypi are called Platypups");
            var subtitleFont = FontFactory.GetFont("Times Roman", 13, BaseColor.BLACK);
            subTitle.Font = subtitleFont;
            doc.Add(subTitle);

            var importantNotice = new Paragraph("Teenage platypi are sometimes called Platydude[tte]s");
            var importantNoticeFont = FontFactory.GetFont("Courier", 13, BaseColor.RED);
            importantNotice.Font = importantNoticeFont;
            doc.Add(importantNotice);

            ListColumns lc;
            for (int i = 0; i < listOfListItems.Count; i++)
            {
                lc = listOfListItems[i];
                sb.AppendLine(String.Format(@"<p>Request date is {0}; Payee Name is {1}; Remit Address or Mail Stop is {2}; Last 4 of SSN or ITIN is {3}; 204 Submitted or on file is {4}; Requester Name is {5}; Dept or Div Name is {6}; Phone is {7}; Email is {8}</p>",
                    lc.li_requestDate, lc.li_payeeName, lc.li_remitAddressOrMailStop, lc.li_last4SSNDigitsOrITIN, lc.li_204SubmittedOrOnFile, lc.li_requesterName, lc.li_deptDivName, lc.li_phone, lc.li_email));
            }

            String htmlToRenderAsPDF = sb.ToString();

            //XMLWorker also reads from a TextReader and not directly from a string
            using (var srHtml = new StringReader(htmlToRenderAsPDF))
            {
                XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
            }

            doc.Close();
        }
    }
    try
    {
        var bytes = ms.ToArray();
        var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "iTextSharpTest.pdf");
        File.WriteAllBytes(testFile, bytes);
    }
    catch (Exception ex)
    {
        String exMsg = ex.Message;
        ; // what is "ex" here?
    }

我正在设置两种字体大小（18 号和 13 号）、两种颜色（黑色和红色）、两种字体（"Courier" 和 "Times Roman"） PDF 幻想化似乎仍然是徒劳的（向 Vachel Lindsay 和 Abraham Lincoln 道歉）。

Answer 1

创建Paragraph时应使用字体：

Font f = new Font(FontFamily.COURIER);
Paragraph p = new Paragraph("text", f);
document.add(p);

或者您应该等到设置好字体后再添加内容：

Paragraph p = new Paragraph();
Font f = new Font(FontFamily.COURIER);
p.setFont(f);
p.addText("text");
document.add(p);

在你的代码中，你有这样的东西：

Paragraph p = new Paragraph("text");
Font f = new Font(FontFamily.COURIER);
p.setFont(f);
document.add(p);

使用 setFont() 设置字体时，您为将添加到段落的文本设置字体，而不是为段落中已存储的文本设置字体。

例如：

Paragraph p = new Paragraph("font 1 ");
p.setFont(new Font(FontFamily.COURIER);
p.add("font 2");
document.add(p);

这将添加默认字体 font 1 和 Courier 字体 font 2 的文本。
