Question

我现在可以制作的PDF： screenshot http://yart.com.au/junk/itextsharp_problem.jpg

我希望文本填满左下方的空格。我怎样才能做到这一点？谢谢！

这是我的代码：

private static void CreatePdf4(string pdfFilename, string heading, string text, string[] photos, string emoticon)
{
  Document document = new Document(PageSize.A4.Rotate(), 26, 36, 0, 0);
  PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(pdfFilename, FileMode.Create));
  document.Open();

  // Heading
  Paragraph pHeading = new Paragraph(new Chunk(heading, FontFactory.GetFont(FontFactory.HELVETICA, 54, Font.NORMAL)));
  document.Add(pHeading);

  // Photo 1
  Image img1 = Image.GetInstance(HttpContext.Current.Server.MapPath("/uploads/photos/" + photos[0]));
  img1.ScaleAbsolute(350, 261);
  img1.SetAbsolutePosition(46, 220);
  img1.Alignment = Image.TEXTWRAP;
  document.Add(img1);

  // Photo 2
  Image img2 = Image.GetInstance(HttpContext.Current.Server.MapPath("/uploads/photos/" + photos[1]));
  img2.ScaleAbsolute(350, 261);
  img2.SetAbsolutePosition(438, 220);
  img2.Alignment = Image.TEXTWRAP;
  document.Add(img2);

  // Text

  PdfContentByte cb = writer.DirectContent;
  cb.BeginText();
  cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, false), 18);
  cb.SetTextMatrix(46, 175);
  cb.ShowText(text);
  cb.EndText();

  // Photo 3
  Image img3 = Image.GetInstance(HttpContext.Current.Server.MapPath("/uploads/photos/" + photos[2]));
  img3.ScaleAbsolute(113, 153);
  img3.SetAbsolutePosition(556, 38);
  document.Add(img3);

  // Emoticon
  Image imgEmo = Image.GetInstance(HttpContext.Current.Server.MapPath("/Content/images/" + emoticon));
  imgEmo.ScaleToFit(80, 80);
  imgEmo.SetAbsolutePosition(692, 70);
  document.Add(imgEmo);

  document.Close();
}

解决

  PdfContentByte cb = writer.DirectContent;
  ColumnText ct = new ColumnText(cb);
  ct.SetSimpleColumn(new Phrase(new Chunk(text, FontFactory.GetFont(FontFactory.HELVETICA, 18, Font.NORMAL))),
                     46, 190, 530, 36, 25, Element.ALIGN_LEFT | Element.ALIGN_TOP);
  ct.Go();

对于Cocoa Dev，是的，我们可以使用PdfPCell的SetLeading属性为文本设置行间距： PdfPCell.SetLeading(float fixedleading, float multiplied leading);

如何定位和包装长文本？
