使用ITextSharper小结

  用到了生成PDF版的合同,上网研究了一圈,发现不需要服务器端安装插件的,比较好用的就是这个ITextSharper了,于是便开始了研究。

1.解决汉字不显示的问题,指定一下字体,默认的字体好像不支持中文,C:\Windows\Fonts\simsun.ttc,这是字体的路径。

BaseFont songTiFont = BaseFont.CreateFont(@"C:\Windows\Fonts\simsun.ttc,0", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);//宋体
        BaseFont heiTiFont = BaseFont.CreateFont(@"C:\Windows\Fonts\simsun.ttc,0", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);//黑体
var titlePara = new iTextSharp.text.Paragraph("借 款 合 同", new Font(heiTiFont, 22, iTextSharp.text.Font.BOLD));

2.PDF中基本的概念:

从大到小:Document文档>Paragraph段落>Phrase短句>Chunk块

这个概念跟HTML差不多,Document=<Html>,Paragraph=<P> ,Phrases=<div>,Chunk=<Span>,

Phrase这个我可能理解的不太到位,大家参考就好了,音译过来是短句的意思,是一系列以特定间距(两行之间的距离)作为参数的块,一个短句有一个主字体,但短句中的一些块具有不同于主字体的字体,你有更多的选择去创建短句(网上抄的)。
这个博文讲的比较好,值得参考:http://www.cnblogs.com/LifelongLearning/archive/2011/03/30/2000072.html

3.设置

我用下划线后发现两行之间距离有点近了,研究了半天,发现在创建Paragraph的时候去指定一下就好了。

var loanerPara = new Paragraph(25);

需要左对齐或者右对齐的时候,使用下面的这句

 titlePara.Alignment = Element.ALIGN_CENTER;

4.基本写法

懒得去分解了,贴了一部分代码上来。基本思路是,创建Document->指定大小(如A4)->创建实例->打开文档->创建段落(中文一定要指定字体)->创建块->把块加到段落中->把段落加到文档中 。

  private void button1_Click(object sender, EventArgs e)
        {
            string fileName = string.Empty;
            SaveFileDialog dlg =new  SaveFileDialog();
            dlg.FileName = "借款合同";
            dlg.DefaultExt = ".pdf";
            dlg.Filter = "Text documents (.pdf)|*.pdf";
            var result = dlg.ShowDialog();
            if (result ==DialogResult.OK)
            {
                fileName = dlg.FileName;
                Document document = new Document(PageSize.A4);//从大到小:Document文档>Paragraph段落>Chunk块
                
                PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(fileName, FileMode.Create));
                document.Open();
               // BaseFont songTiFont = BaseFont.CreateFont(@"H:\Windows\Fonts\simsun.ttc,0", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);//宋体
                //BaseFont heiTiFont = BaseFont.CreateFont(@"H:\Windows\Fonts\simsun.ttc,0", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);//黑体
                #region 生成标题
                var titlePara = new iTextSharp.text.Paragraph("借 款 合 同", new Font(heiTiFont, 22, iTextSharp.text.Font.BOLD));
                titlePara.Alignment = Element.ALIGN_CENTER;
                document.Add(titlePara);
                #endregion
                #region 借款号
                var loanNumberPara = new Paragraph(string.Format("{0}借字第{1}号",DateTime.Now.Year,00001),new Font(songTiFont,12));
                loanNumberPara.Alignment = Element.ALIGN_RIGHT;//设置右对齐
                document.Add(loanNumberPara);
                #endregion
                #region 出借人
                var investPara=new Paragraph(25);
                investPara.Add(CreateSongtiBoldChunk("出借人"));
                investPara.Add(CreateSongtiNomalChunk("(以下简称甲方):"));
                investPara.Add(CreateSongtiUnderLineChunk("  网络名(昵称) "));
                document.Add(investPara);
                #endregion

                #region 借款人
                var loanerPara = new Paragraph(25);
                loanerPara.Add(CreateSongtiBoldChunk("借款人"));
                loanerPara.Add(CreateSongtiNomalChunk("(以下简称乙方):"));
                loanerPara.Add(CreateSongtiUnderLineChunk("            "));
                loanerPara.Add(CreateSongtiNomalChunk("身份证号:"));
                loanerPara.Add(CreateSongtiSpeaceUnderLineChunk(20));
                document.Add(loanerPara);
                #endregion

                #region 通讯地址
                var addressPara = new Paragraph(25);
                addressPara.Add(CreateSongtiNomalChunk("通讯地址:"));

                addressPara.Add(CreateSongtiSpeaceUnderLineChunk(10));

                document.Close();
            }
        }

            {
                sb.Append(" ");
            }
           return  CreateSongtiUnderLineChunk(sb.ToString());
        }
