添加文档信息
/// <summary> /// 设置页面大小、作者、标题等相关信息设置 /// </summary> private void CreatePdfSetInfo() { string fileName = string.Empty; //设置页面大小 iTextSharp.text.Rectangle pageSize = new iTextSharp.text.Rectangle(216f, 716f); pageSize.BackgroundColor = new iTextSharp.text.BaseColor(0xFF, 0xFF, 0xDE); //设置边界 Document document = new Document(pageSize, 36f, 72f, 108f, 180f); PdfWriter.GetInstance(document, new FileStream(fileName, FileMode.Create)); // 添加文档信息 document.AddTitle("压试块"); document.AddSubject("Demo of PDFInfo"); document.AddKeywords("Info, PDF, Demo"); document.AddCreator("SetPdfInfoDemo"); document.AddAuthor("同之杰"); document.Open(); // 添加文档内容 for (int i = 0; i < 5; i++) { document.Add(new iTextSharp.text.Paragraph("Hello World! Hello People! " + "Hello Sky! Hello Sun! Hello Moon! Hello Stars!")); } document.Close(); }
空白换行
//设置一个空白换行 float normalLineHeight = 25f; Paragraph pBlank = new Paragraph(" ", normalFont); pBlank.Leading = normalLineHeight; document.Add(pBlank);
模板应用
public void AAA() { string filename = DateTime.Now.ToString("yyyyMMddHHmmss").ToString() + ".pdf"; var filePath = WebAppSettings.ErpUploadRootPath + "\\BizImages\\YaliJi\\" + filename; float w = PageSize.A4.Width; float h = PageSize.A4.Height; Rectangle rect = new Rectangle(0, 0, w, 3 * h); Document document = new Document(rect); PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(filePath, FileMode.Create)); Rectangle crop = new Rectangle(0, 2 * h, w, 3 * h); writer.CropBoxSize = crop; document.Open(); PdfContentByte content = writer.DirectContent; PdfTemplate template = content.CreateTemplate(rect.Width, rect.Height); template.SaveState(); template.SetColorFill(new BaseColor(0xFF, 0xFA, 0xCD)); template.Rectangle(0, 0, w, h); template.FillStroke(); template.RestoreState(); template.SaveState(); template.SetColorFill(new BaseColor(0xFF, 0xFA, 0xCD)); template.Rectangle(0, h, w, h); template.FillStroke(); template.RestoreState(); template.SaveState(); template.SetColorFill(new BaseColor(0xFF, 0xFA, 0xCD)); template.Rectangle(0, 2 * h, w, h / 2); template.FillStroke(); template.RestoreState(); content.AddTemplate(template, 1, 0, 0, -1, 0, rect.Height); crop = new Rectangle(0, h, w, 2 * h); writer.CropBoxSize = crop; document.NewPage(); content.AddTemplate(template, 1, 0, 0, -1, 0, rect.Height); crop = new Rectangle(0, 0, w, h); writer.CropBoxSize = crop; document.NewPage(); content.AddTemplate(template, 1, 0, 0, -1, 0, rect.Height); document.Close(); }
