本文实例为大家分享了C#生成PDF文件流的具体代码,供大家参考,具体内容如下
1、设置字体

static BaseFont FontBase = BaseFont.CreateFont( "C:\WINDOWS\FONTS\STSONG.TTF" , BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
static iTextSharp.text.Font bodyFont = new iTextSharp.text.Font(FontBase, 12);
static iTextSharp.text.Font titleFont = new iTextSharp.text.Font(FontBase, 18);
static iTextSharp.text.Font paragraphFont = new iTextSharp.text.Font(FontBase, 15);
static iTextSharp.text.Font linkFont = new iTextSharp.text.Font(FontBase, 12, Font.UNDERLINE, BaseColor.BLUE);

2.生成PDF文件流返回byte数组
- public byte[] DocCreate(System.Drawing.Image image, List<TreeNodes> list)
- {
- MemoryStream file = new MemoryStream();
- string fileName = string.Empty;
- Rectangle page = PageSize.A4;
- float y = page.Height;
- Document document = new Document(page, 15, 15, 30, 30);
- float docWidth = page.Width - 15 * 2;
- float docHeight = page.Height - document.BottomMargin - document.TopMargin;
- PdfWriter writer = PdfWriter.GetInstance(document, file);
- writer.CloseStream = false;
- writer.Open();
- PdfContentByte cb = writer.DirectContent;
- document.Open();
- //标题
- Paragraph title = new Paragraph(new Chunk("标题", titleFont));
- title.Alignment = Element.ALIGN_CENTER;
- document.Add(title);
- //图片
- iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(image, ImageFormat.Png);
- float widthSzie = (page.Width - 30) / img.Width;
- if (widthSzie < 1)
- {
- img.ScalePercent(widthSzie * 100);
- }
- document.Add(img);
- //文献出处
- Paragraph p2 = new Paragraph(new Chunk("出处", paragraphFont));
- p2.IndentationLeft = indentationLeft;
- document.Add(p2);
- InitData(list);//初始化业务数据
- CreateSteps(list, document, list.FirstOrDefault(it => it.PID == 0));//添加业务数据
- ////添加印章
- //iTextSharp.text.Image whyz = iTextSharp.text.Image.GetInstance(whyzPath);
- //whyz.ScalePercent(50);
- //whyz.PaddingTop = 100;
- //whyz.Alignment = Element.ALIGN_RIGHT;
- //document.Add(whyz);
- //添加日期
- Paragraph createtime = new Paragraph(new Chunk(DateTime.Now.ToLongDateString().ToString(), bodyFont));
- createtime.Alignment = Element.ALIGN_RIGHT;
- //createtime.SpacingBefore = -80;
- createtime.PaddingTop = 200;
- document.Add(createtime);
- document.Close();
- file.Position = 0;
- MemoryStream newfile = SetWaterMark(file, "水印内容", docWidth, docHeight);//添加水印,见另外一篇博客
- newfile.Position = 0;//重置流指针位置
- byte[] bytes = new byte[newfile.Length];
- newfile.Read(bytes, 0, bytes.Length);
- return bytes;
- }
