public void onChapter(PdfWriter writer, Document document,
float paragraphPosition, Paragraph title) {
header[1] = new Phrase(title.getContent());
pagenumber = 1;
}

public void onStartPage(PdfWriter writer, Document document) {
pagenumber++;
}

public void onEndPage(PdfWriter writer, Document document)
{

Rectangle rect1 = writer.getBoxSize(“box”);
ColumnText.showTextAligned(writer.getDirectContent(),
Element.ALIGN_RIGHT, new Phrase(“”),
rect1.getRight(), rect1.getTop(), 0);
ColumnText.showTextAligned(writer.getDirectContent(),
