        System.out.println("Chapter 13 example pdfreader: reading an existing PDF file");

 

        try {
            // we create a reader for a certain document
            PdfReader reader = new PdfReader("D:/backup/UML/JDK14_tutorial.pdf");
            // we retrieve the total number of pages
            int n = reader.getNumberOfPages();
            // we retrieve the size of the first page
            Rectangle psize = reader.getPageSize(1);
           
            float width = psize.width();
            float height = psize.height();
                 // step 1: creation of a document-object

 

           // Document document = new Document(psize, 50, 50, 50, 50);
            Document document =new Document(PageSize.A4.rotate());
           
            // step 2: we create a writer that listens to the document

 

            PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("jdk1.4.11.pdf"));

 

            // step 3: we open the document

 

           /* try {

 

                Watermark watermark = new Watermark(Image.getInstance("C:/Documents and Settings/bj21812/My Documents/My Pictures/annu.bmp"), 200, 320);

 

                document.add(watermark);

 

            }

 

            catch(Exception e) {

 

                System.err.println("Are you sure you have the file 'watermark.jpg' in the right path?");

 

            }
*/
            document.open();

 

            // step 4: we add content
          
            PdfContentByte cb = writer.getDirectContent();

 

            int i = 0;

 

            int p = 0;

 

            System.out.println("There are " + n + " pages in the document.");

 

            while (i < n) {

 

                document.newPage();

                p++;

 

                i++;

 

              PdfImportedPage page1 = writer.getImportedPage(reader, i);

 

              cb.addTemplate(page1, .5f, 0, 0, .5f, 0, width / 2);
               
                
                System.err.println("processed page " + i);             

 

                if (i < n) {

 

                    i++;

 

                    PdfImportedPage page2 = writer.getImportedPage(reader, i);

 

                    cb.addTemplate(page2, .5f, 0, 0, .5f, width / 2, height / 2);

 

                    System.err.println("processed page " + i);

 

                }

                    System.err.println("processed page " + i);

 

                }*/

 

                /*cb.setRGBColorStroke(255, 0, 0);

 

               cb.moveTo(0, height / 2);

 

                cb.lineTo(width, height / 2);

 

                cb.stroke();

 

                cb.moveTo(width / 2, height);

 

                cb.lineTo(width / 2, 0);

 

                cb.stroke();

 

                BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);

 

                cb.beginText();

 

                cb.setFontAndSize(bf, 14);

 

               cb.showTextAligned(PdfContentByte.ALIGN_CENTER, "page " + p + " of " + ((n / 4) + (n % 4 > 0? 1 : 0)), width / 2, 40, 0);

 

                cb.endText();

 

            }

 

            // step 5: we close the document

 

            document.close();

 

        }

 

        catch (Exception de) {

 

            de.printStackTrace();

 

        }
