Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    Document document = new Document(PageSize.A4);
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("2.pdf"));
    document.open();//from w ww.j a  v  a 2s.  c  o m
    PdfContentByte cb = writer.getDirectContent();
    ColumnText ct = new ColumnText(cb);
    BufferedReader reader = new BufferedReader(new FileReader("a.txt"));
    String line;
    while ((line = reader.readLine()) != null) {
        ct.addText(new Phrase(line + "\n"));
    }
    reader.close();
    ct.setSimpleColumn(36, 36, PageSize.A4.width() - 36, PageSize.A4.height() - 36, 18,
            Element.ALIGN_JUSTIFIED);
    int status = ColumnText.START_COLUMN;
    while (ColumnText.hasMoreText(status)) {
        status = ct.go();
        ct.setYLine(PageSize.A4.height() - 36);
        document.newPage();
    }
    document.close();
