Hello,
Below is a method to add headers and footers to an existing document.
It works fine on most document but sometimes, on some pages, especially
if they seem to have been scanned, the header/footer is not displayed.
It seems to be here because a selection on something invisible can be
performed. There must be a foreground/background issue there but I was
unable to find any clue to make sure the my header/footer are guaranteed
to appear.
Any clue ?

import com.lowagie.text.pdf.*;
/**
* Add header + footer
*/
public static boolean addHeadFoot(
String ficpdf_orig, String
ficpdf_dest,
String sheader,
String sfooter) {
int n;
Document underdocument = null;
Document overdocument = null;
//PdfCopy writer = null;
PdfStamper pdfstamper = null;
PdfReader reader;
File filefrom, fileto;
PdfContentByte undercontent ;
PdfContentByte overcontent ;
PdfPTable pdffooter=null;
PdfPTable pdfheader = null;
float fret;
try {
// we create a reader for a certain document
reader = new PdfReader(ficpdf_orig);
reader.consolidateNamedDestinations();
// we retrieve the total number of pages
n = reader.getNumberOfPages();
// step 1: creation of a document-object
pdfstamper = new PdfStamper(reader, new
FileOutputStream(ficpdf_dest));
// step 3: we open the document
if (sheader.length() > 0) {
pdfheader = new PdfPTable(1);
pdfheader.setTotalWidth(600);
pdfheader.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);
pdfheader.getDefaultCell().setBorderColor(new
Color(255, 255, 255));
pdfheader.addCell(new Phrase(sheader, new
Font(Font.HELVETICA, 8, Font.ITALIC, new Color(0, 0, 0))));
}
if (sfooter.length() > 0) {
pdffooter = new PdfPTable(1);
pdffooter.setTotalWidth(550);
pdffooter.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);
pdffooter.getDefaultCell().setVerticalAlignment(Element.ALIGN_BOTTOM);
pdffooter.getDefaultCell().setBorderColor(new
Color(255, 255, 255));
pdffooter.addCell(new Phrase(sfooter, new
Font(Font.HELVETICA, 8, Font.ITALIC, new Color(0, 0, 0)) ));
}
// step 4: we add content
for (int i = 0 ; i < n ; ) {
++i;
undercontent = pdfstamper.getUnderContent(i);
overcontent = pdfstamper.getOverContent(i);
underdocument = undercontent.getPdfDocument();
overdocument = overcontent.getPdfDocument();
if (sheader.length() > 0) {
fret = pdfheader.writeSelectedRows(0, -1, 0,
overdocument.top() , overcontent);
}
if (sfooter.length() > 0) {
fret = pdffooter.writeSelectedRows(0, -1, 0,
underdocument.bottom(), undercontent);
}
}
// step 5: we close the document
pdfstamper.close();
reader.close();
}
catch(Exception e) {
return false;
}
return true;
}
Regards.
