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:WINDOWSFONTSSTSONG.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,15,30,30); 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,bytes.Length); return bytes; } 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
