[FIXED] iText PDF orientation

Issue

I am using itextpdf version 5.0.1 to cut pages into specified page numbers.I am facing a problem when I try to cut a PDF which is oriented in landscape. When I use the following code the landscape oriented pdfs are getting cut like a potrait oriented pdf and the rest is missing. The code I am using is:

    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.InputStream;
    import java.io.OutputStream;
    import com.itextpdf.text.Document;
    import com.itextpdf.text.pdf.PdfContentByte;
    import com.itextpdf.text.pdf.PdfImportedPage;
    import com.itextpdf.text.pdf.PdfReader;
    import com.itextpdf.text.pdf.PdfWriter;
    public class PDFSplitExample {
    static void splitPdfFile(InputStream inputPdf,
                OutputStream outputStream, int startPage,
                int endPage) throws Exception{
            //Create document and pdfReader objects.
            Document document = new Document();
            PdfReader pdfReader = new PdfReader(inputPdf);
             //Get total no. of pages in the pdf file.
    int totalPages = pdfReader.getNumberOfPages();

    //Check the startPage should not be greater than the endPage
    //and endPage should not be greater than total no. of pages.
    if(startPage > endPage || endPage > totalPages) {
       System.out.println("Kindly pass the valid values " +
            "for startPage and endPage.");
    }else{
         // Create writer for the outputStream
        PdfWriter writer = 
            PdfWriter.getInstance(document, outputStream);

        //Open document
        document.open();

       //Contain the pdf data.
        PdfContentByte pdfContentByte = 
                writer.getDirectContent(); 
        PdfImportedPage page;

        while(startPage <= endPage) {
          document.newPage();
          page=writer.getImportedPage(pdfReader, startPage);
          pdfContentByte.addTemplate(page, 0, 0);
          startPage++;
        }

        //Close document and outputStream.
        outputStream.flush();
        document.close();
        outputStream.close();
    }          
}

public static void main(String args[]){
 try {          
    //Prepare output stream for 
    //new pdf file after split process.
        OutputStream outputStream1 = 
                new FileOutputStream("SplitFile1.pdf");
        OutputStream outputStream2 = 
                new FileOutputStream("SplitFile2.pdf");

        //call method to split pdf file.
        splitPdfFile(new FileInputStream("TestFile.pdf"),
                outputStream1, 1, 10);    
        splitPdfFile(new FileInputStream("TestFile.pdf"),
                outputStream2, 11, 20);  

        System.out.println("Pdf file splitted successfully.");
  } catch (Exception e) {
    e.printStackTrace();
  }
 }
}

Solution

The following code solved my problem

    private static void manipulateWithCopy(PdfReader reader,String result)
        throws IOException, DocumentException {
    int n = reader.getNumberOfPages();
    Document document = new Document();
    PdfCopy copy = new PdfCopy(document, new FileOutputStream(result));
    document.open();
    for (int i = 0; i < n;) {
        copy.addPage(copy.getImportedPage(reader, ++i));
    }
    document.close();
}
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    try{
    String path= "path/of/the/file/in/the/smb/storage";
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, "username", "password");//storing authentication details
        SmbFile sFile = new SmbFile(path, auth);
        FileOutputStream fileOutputStream;
        InputStream fileInputStream;
        String destFilename = "path/to/the/file";
        fileOutputStream = new FileOutputStream(destFilename);
        fileInputStream = sFile.getInputStream();
        byte[] buf;
        int len;
        buf = new byte[16 * 1024 * 1024];
        while ((len = fileInputStream.read(buf)) > 0) {
            fileOutputStream.write(buf, 0, len);
        }
        InputStream inputPdf = new FileInputStream(destFilename);
        PdfReader reader= new PdfReader(inputPdf);
        reader.selectPages(stpg+"-"+endpg);
        manipulateWithCopy(reader,destFilename);
        reader.close();
    }
    catch(Exception e){
        System.out.println(e);
    }
}
