49. Write a SSJS function to create the PDF using this template. Window Show Eclipse Views Other Package Explorer
50. SSJS function for PDF generation //1. Load the java packages importPackage(com.itextpdf); importPackage(com.itextpdf.text); importPackage(com.itextpdf.text.pdf); importPackage(com.itextpdf.text.pdf.fonts); importPackage(java.io);
51. 2. Initialise & get the template var theDirectory= session.getEnvironmentString("Directory",true); var reader = new com.itextpdf.text.pdf.PdfReader (theDirectory + "/TaxInvoice.pdf"); var fileOut = new java.io.FileOutputStream(filename); var stamper = new com.itextpdf.text.pdf.PdfStamper(reader, fileOut); var canvas = stamper.getOverContent(1);
52. 3. Embed your fonts var arial = new BaseFont.createFont("c:/windows/fonts/arial.ttf", BaseFont.WINANSI, BaseFont.EMBEDDED); var arialbd = new BaseFont.createFont("c:/windows/fonts/arialbd.ttf", BaseFont.WINANSI, BaseFont.EMBEDDED); var NORMAL = new Font(arial,10); var BOLD = new Font(arialbd,10); var BOLD11 = new Font(arialbd,11); var BOLD12 = new Font(arialbd,12);
53. 4. Create and place your data var client = new Phrase(doc.getItemValueString("Client"),NORMAL); ColumnText.showTextAligned(canvas, Element.ALIGN_LEFT, client, 65, 670, 0); var lcost = new Phrase(@Text(resp.getItemValueDouble("Cost"),"C,"), BOLD11); ColumnText.showTextAligned(canvas, Element.ALIGN_RIGHT, lcost, 563, 533 - (i*44), 0);
54. 5.Close and attach stamper.close(); fileOut.close(); //attach the pdf var rtitem:NotesRichTextItem= doc.createRichTextItem("Invoice"); rtitem.embedObject(NotesEmbeddedObject.EMBED_ATTACHMENT, "", filename, null);
55. Download Control fix var serv = session.getHttpURL().split("?")[0]; if (!@IsNewDoc()) {return serv + "/" + sessionScope.invoiceDbName+ "/0/" + document1.getDocument().getUniversalID() + "$FILE/"+ rowData.getName(); } else {return "#";} if (@ClientType()=="Notes") return "/.ibmmodres/" + "domino/OpenAttachment/"+ database.getServer() + "!!"+sessionScope.invoiceDbName + "/"+document1.getDocument().getUniversalID() + "/attachment/"+rowData.getName();
