pdf文件的创建(第三方插件)

代码如下：

Code

 1 /// <summary>
 2         /// 生成PDF
 3         /// </summary>
 4         /// <param name="sender"></param>
 5         /// <param name="e"></param>
 6         protected void btnSave_Click(object sender, EventArgs e)
 7         {
 8             DataTable dt = bll.GetSupply();
 9             string fontPath = @"c:\windows\fonts\SIMKAI.ttf";//楷体字
10             //创建PDF文档对象
11             Document doc = new Document();
12             //实例化生成的文档
13             PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(this.txtPath.Text.Trim(), FileMode.Create));
14             BaseFont baseFont = BaseFont.CreateFont(fontPath, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
15             Font font = new Font(baseFont, 10);
16             doc.AddAuthor(this.txtAuthor.Text.Trim());//作者
17             doc.AddKeywords(this.txtKeyWords.Text.Trim());//关键字
18             doc.AddSubject(this.txtZhuti.Text.Trim());//主题
19             doc.AddTitle(this.txtTitle.Text.Trim());//标题
20             //页眉  页眉和页脚的HeaderFooter 类 只存在于 Itextsharp 5.0 version以下，高版本现在已经Remove HeaderFooter类
21             HeaderFooter header = new HeaderFooter(new Phrase(this.txtHeader.Text.Trim()), true);
22             header.Border = Rectangle.NO_BORDER;
23             doc.Header = header;

28 
29             doc.Open();
30             //添加图片
31             iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(@"C:\Documents and Settings\Administrator\My Documents\My Pictures\129810262468791250.png");
32             doc.Add(jpg);
33             doc.Add(new Phrase(this.txtContent.Text.Trim(), font));
34             //创建Table

51                 {

53                 }
54             }
55             doc.Add(table);
56             doc.Close();
57             writer.Close();
58         }
59 
60         /// <summary>

66         {
67             Response.Clear();
68             Response.ContentType = "Application/pdf";

字体文件一般保存在Windows/fonts目录中，扩展名为TTF、TTC，TTC扩展名的字体是一个集合。在Windows系统中集中标准字体的文件名称：

SIMSUN.TTC 宋体和新宋体

SIMKAI.TTF 楷体

SIMHEI.TTF 黑体

SIMFANG.TTF 仿宋体

STZHONGS.TTF 中宋体

字体的应用例子

字体应用

1   Document document = new Document();
2                 PdfWriter.GetInstance(document, new FileStream(@"c:\hello.pdf", FileMode.Create));
3                 BaseFont baseFont = BaseFont.CreateFont(@"C:\WINDOWS\Fonts\SIMYOU.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
4                 Font font = new Font(baseFont, 12);
5                 document.Open();
6                 document.Add(new Paragraph("测试一下数据", font));
7                 document.Close();

字体集合的应用

字体集合

 1  Document document = new Document();
 2                 PdfWriter.GetInstance(document, new FileStream(@"c:\hello.pdf", FileMode.Create));
 3                 BaseFont baseFont1 = BaseFont.CreateFont(@"C:\WINDOWS\Fonts\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
 4                 Font font1 = new Font(baseFont1, 12);
 5 
 6                 BaseFont baseFont2 = BaseFont.CreateFont(@"C:\WINDOWS\Fonts\SIMSUN.TTC,0", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
 7                 Font font2 = new Font(baseFont2, 12);
 8                 document.Open();
 9                 document.Add(new Paragraph("测试一下数据", font1));
10                 document.Add(new Paragraph("测试一下数据", font2));
11                 document.Close();

如果以下代码，输入中文字体不会显示或者乱码

code

1  Document document = new Document();
2                 PdfWriter.GetInstance(document, new FileStream(@"c:\hello.pdf", FileMode.Create));
3                 BaseFont baseFont1 = BaseFont.CreateFont(@"C:\WINDOWS\Fonts\ROCKB.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
4                 Font font1 = new Font(baseFont1, 12);
5                 document.Open();
6                 document.Add(new Paragraph("测试一下", font1));
7                 document.Close();

原因是指定的字体是支持英文不支持中文的，此时我们只需要修改我们的指定的字体就可以。

创建table

table

 1    Document document = new Document();
 2                 PdfWriter.GetInstance(document, new FileStream(@"c:\hello.pdf", FileMode.Create));
 3                 document.Open();
 4                 iTextSharp.text.Table table = new iTextSharp.text.Table(3);
 5                 table.Cellpadding = 0;
 6                 table.Cellspacing = 0;
 7                 table.BorderWidth = 0.5f;
 8                 table.BorderColor = Color.BLUE;
 9                 Cell cell = new Cell(" table header");
10 
11                 cell.Colspan = 3;
12                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
13                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
14                 cell.Header = true;
15                 table.AddCell(cell);
16 
17 
18                 cell = new Cell("cell 1");
19                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
20                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
21                 cell.Rowspan = 2;
22                 table.AddCell(cell);
23 
24                 cell = new Cell("cell 2"); 
25                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
26                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
27                 table.AddCell(cell);
28 
29                 cell = new Cell("cell 3");
30                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
31                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
32                 table.AddCell(cell);
33 
34                 cell = new Cell("cell 4"); 
35                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
36                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
37                 table.AddCell(cell);
38 
39                 cell = new Cell("cell 5"); 
40                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
41                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
42                 table.AddCell(cell);
43 
44                 cell = new Cell("cell 6"); 
45                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
46                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
47                 table.AddCell(cell);
48 
49                 cell = new Cell("cell 7"); 
50                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
51                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
52                 cell.Rowspan = 2;
53                 cell.Colspan = 2;
54                 table.AddCell(cell);
55 
56                 cell = new Cell("cell 8"); 
57                 cell.HorizontalAlignment = Element.ALIGN_CENTER;
58                 cell.VerticalAlignment = Element.ALIGN_MIDDLE;
59                 table.AddCell(cell);
60                 document.Add(table);
61                 document.Close();

PDF加密

用到PdfWriter实例的setEncryption（bool strength,string userPassword ,string ownerPassWord,int permission）函数

Code

1       Document doc = new Document();
2             PdfWriter we = PdfWriter.GetInstance(doc, new FileStream(@"c:\d.pdf", FileMode.Create));
3             we.SetEncryption(PdfWriter.STRENGTH128BITS, "test", "admin", PdfWriter.ALLOW_COPY | PdfWriter.ALLOW_PRINTING|PdfWriter.ALLOW_MODIFY_CONTENTS);
4             doc.Open();
5             doc.Add(new Paragraph("Hello World!"));
6             doc.Close();

Permission参数为下列常量

PdfWriter.AllowPrinting

PdfWriter.AllowCopy
