Dear Team,

I am generating pdf file in xpages.

Working fine .But i want to add logo on header and footer how to add please guide me ..

importPackage(com.itextpdf);

//Initialization

var con = facesContext.getExternalContext();

var response:com.ibm.xsp.webapp.XspHttpServletResponse = con.getResponse();

var fileName=dt.getDateOnly()+".pdf";

//setting response headers for browser to recognize data

response.setContentType("application/pdf");

response.setHeader("Cache-Control", "no-cache");

response.setDateHeader("Expires", -1);

response.setHeader("Content-Disposition","attachment; filename=\""+fileName+"\"");

var imageString="logo.jpeg";

// Setup the PDF Output Stream

var newPDF:com.itextpdf.text.Document = new com.itextpdf.text.Document();

//var image:com.itextpdf.text.Image = new com.itextpdf.text.Image.getInstance(imagestring);

var writer = com.itextpdf.text.pdf.PdfWriter.getInstance(newPDF,response.getOutputStream());

newPDF.open();

//Add Imgae

newPDF.add(new com.itextpdf.text.Paragraph("To,"));

newPDF.add(new com.itextpdf.text.Paragraph(getComponent("inputText1").getValue()));

newPDF.add(new com.itextpdf.text.Paragraph("Sub: "+getComponent("inputText2").getValue()));

newPDF.add(new com.itextpdf.text.Paragraph("Sir,"));

newPDF.add(new com.itextpdf.text.Paragraph(" With refrence to the above said work, we are pleased to offer our best price as follows:-"));

newPDF.add(new com.itextpdf.text.Paragraph(''));

newPDF.add(new com.itextpdf.text.Chunk.NEWLINE);

//Create a new table with 3 cells, width = 100%

var table = new com.itextpdf.text.pdf.PdfPTable(6);

//Value Description

var desc1=getComponent("inputText180").getValue();

var desc2=getComponent("inputText181").getValue();

var desc3=getComponent("inputText182").getValue();

var nos1=getComponent("inputText183").getValue();

var rate1=getComponent("inputText184").getValue();

var Qnty1=getComponent("inputText185").getValue();

var price1=getComponent("inputText186").getValue();

//description:inputText180

var cell1 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("S.No."));

var cell2 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("Description"));

var cell3 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("Nos"));

var cell4 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("Rate"));

var cell5 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("Quantity"));

var cell6 = new com.itextpdf.text.pdf.PdfPCell(new com.itextpdf.text.Paragraph("Price"));

table.setWidthPercentage(100);

table.addCell(cell1);

table.addCell(cell2);

table.addCell(cell3);

table.addCell(cell4);

table.addCell(cell5);

table.addCell(cell6);

newPDF.add(table);

newPDF.add(

//End Here

newPDF.close();

writer.close();

Thanks in advance

Adding image

I'm not sure, if this is correct way to add header/footer images, but I've used code below to add image to specific location in PDF:

var imagedoc:NotesDocument;

//suppose we have a notes view containing document which holds a logo

imagedoc= database.getView("(images)").getDocumentByKey("LOGO");

var numattachments = session.evaluate("@Attachments", kuvadoc).elementAt(0); //get number of attachments

var logofound:boolean = false;

var data2;

var image:com.lowagie.text.Image;

if (numattachments ==1) {

logofound = true;

var v = session.evaluate("@AttachmentNames", imagedoc).elementAt(0);

var is2 = imagedoc.getAttachment(v).getInputStream(); // reading image to bos

var bos2 = new ByteArrayOutputStream();

var buf2 = new byte[1024];

var len2 = 0;

while ((len2= is2.read(buf2)) > 0) {

bos2.write(buf2, 0, len2);

}

data2 = bos2.toByteArray();

bos2.flush();

is2.close();

image = new com.lowagie.text.Image.getInstance(data2);

image.setAbsolutePosition(400,120); //here you specify image location

image.scaleToFit(100,210); //you can also scale image

}

if (logofound) {

var content:com.lowagie.text.pdf.PdfContentByte;

content = stamper.getOverContent(1); // com.lowagie.text.pdf.PdfStamper needs to be initialized beforehand

content.addImage(image);

}

My example adds image only to first page. If you need to add images to every page, plese look at the link below:
Java IText: Modifying Existing PDF Documents

Working example

This should do the trick. At least it works with iText-2.1.3.jar

I'm sure you can modify this code to fit your need.

function printPdf() {

// Load the java packages

importPackage(com.lowagie);

importPackage(java.io);

//READING IMAGE -->

var imagedoc:NotesDocument;

imagedoc = database.getView("(images)").getDocumentByKey("logo");

if (imagedoc==null) {

return "";

}

var numattachments = session.evaluate("@Attachments", imagedoc).elementAt(0);

var logo:boolean = false;

var data2;

if (numattachments==1) {

logo = true;

var v = session.evaluate("@AttachmentNames", imagedoc).elementAt(0);

var is2 = imagedoc.getAttachment(v).getInputStream();

var bos2 = new ByteArrayOutputStream();

var buf2 = new byte[1024];

var len2 = 0;

while ((len2= is2.read(buf2)) > 0) {

bos2.write(buf2, 0, len2);

}

data2 = bos2.toByteArray();

bos2.flush();

is2.close();

}

var image:com.lowagie.text.Image;

if (logo) {

image = new com.lowagie.text.Image.getInstance(data2);

image.setAbsolutePosition(350,120);

image.scaleToFit(100,210);

}

//<--READING IMAGE

var templatedoc = database.getView("(pdftemplates)").getDocumentByKey("offer");

//Initialization

var con = facesContext.getExternalContext();

var response:com.ibm.xsp.webapp.XspHttpServletResponse = con.getResponse();

//setting response headers for browser to recognize data

response.setContentType("application/pdf");

response.setHeader("Cache-Control", "no-cache");

response.setDateHeader("Expires", -1);

response.setHeader( "Content-Disposition", "attachment; filename=\"offer.pdf\"" );

var pdfdoc:com.lowagie.text.Document = new com.lowagie.text.Document();

var os = new ByteArrayOutputStream();

var copy:com.lowagie.text.pdf.PdfSmartCopy = new com.lowagie.text.pdf.PdfSmartCopy(pdfdoc, os);

pdfdoc.open();

//TESTING ->

pdfdoc.addCreationDate();

pdfdoc.addCreator("my test");

pdfdoc.addTitle("Offer");

// <-TESTING

var is = templatedoc.getAttachment("template.pdf").getInputStream();

var bos = new ByteArrayOutputStream();

var buf = new byte[1024];

var len = 0;

while ((len= is.read(buf)) > 0) {

bos.write(buf, 0, len);

}

var data = bos.toByteArray();

bos.flush();

is.close();

var reader:com.lowagie.text.pdf.PdfReader = new com.lowagie.text.pdf.PdfReader(data); //reading template to memory

var baos = new ByteArrayOutputStream();

var stamper:com.lowagie.text.pdf.PdfStamper = new com.lowagie.text.pdf.PdfStamper(reader, baos);

var form:com.lowagie.text.pdf.AcroFields = stamper.getAcroFields();

form.setField("testfield", "testing only");

//ADDING IMAGE -->

if (logo) {

var content:com.lowagie.text.pdf.PdfContentByte;

//content = stamper.getOverContent(reader.getNumberOfPages());

content = stamper.getOverContent(1);

content.addImage(image);

}

//<--ADDING IMAGE

stamper.setFormFlattening(true); //setting fields to readonly

stamper.close();

var tmppage:com.lowagie.text.pdf.PdfReader = new com.lowagie.text.pdf.PdfReader(baos.toByteArray());

var numpages = tmppage.getNumberOfPages();

for (i=1;i<=numpages;i++)

{

copy.addPage(copy.getImportedPage( tmppage, i));

}

tmppage.close();

baos.flush();

baos.close();

reader.close();

pdfdoc.close();

copy.close();

var rder =response.getOutputStream();

os.writeTo(rder);

os.reset();

templatedoc.recycle();

facesContext.responseComplete();

}

p.s.

Next time please post errors that prevented example to work, because it'll help others and also proofs that you really tried :)
