  In the previous post I showed a class to merge PDF files using iText#, but it seems that there’s a better approach using iTextDotNet:

  csharp:

  using com.lowagie.tools;
  
  class Program
  {
      static void Main(string[] args)
      {
          string[] lista = new string[] { "Meijer.pdf", "P330.pdf", "result.pdf" };
          concat_pdf.main(lista);
      }
  }

  As you can see this is a cleaner and simpler way to merge pdf files. You can download the iTextDotNet .NET Library from this blog or the official Website.

  I’ve made a simple class to merge PDF files using iText#:

  csharp:

  using System;
  using System.Collections.Generic;
  using System.IO;
  using iTextSharp.text;
  using iTextSharp.text.pdf;
  
  public class PdfMerge
  {
      private BaseFont baseFont;
      private bool enablePagination = false;
      private readonly List<PdfReader> documents;
      private int totalPages;
  
      public BaseFont BaseFont
      {
          get { return baseFont; }
          set { baseFont = value; }
      }
  
      public bool EnablePagination
      {
          get { return enablePagination; }
          set
          {
              enablePagination = value;
              if (value && baseFont == null)
                  baseFont = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
          }
      }
  
      public List<PdfReader> Documents
      {
          get { return documents; }
      }
  
      public void AddDocument(string filename)
      {
          documents.Add(new PdfReader(filename));
      }
      public void AddDocument(Stream pdfStream)
      {
          documents.Add(new PdfReader(pdfStream));
      }
      public void AddDocument(byte[] pdfContents)
      {
          documents.Add(new PdfReader(pdfContents));
      }
      public void AddDocument(PdfReader pdfDocument)
      {
          documents.Add(pdfDocument);
      }
  
      public void Merge(string outputFilename)
      {
          Merge(new FileStream(outputFilename, FileMode.Create));
      }
      public void Merge(Stream outputStream)
      {
          if (outputStream == null || !outputStream.CanWrite)
              throw new Exception("OutputStream es nulo o no se puede escribir en éste.");
  
          Document newDocument = null;
          try
          {
              newDocument = new Document();
              PdfWriter pdfWriter = PdfWriter.GetInstance(newDocument, outputStream);
  
              newDocument.Open();
              PdfContentByte pdfContentByte = pdfWriter.DirectContent;
  
              if (EnablePagination)
                  documents.ForEach(delegate(PdfReader doc)
                                    {
                                        totalPages += doc.NumberOfPages;
                                    });
  
              int currentPage = 1;
              foreach (PdfReader pdfReader in documents)
              {
                  for (int page = 1; page <= pdfReader.NumberOfPages; page++)
                  {
                      newDocument.NewPage();
                      PdfImportedPage importedPage = pdfWriter.GetImportedPage(pdfReader, page);
                      pdfContentByte.AddTemplate(importedPage, 0, 0);
  
                      if (EnablePagination)
                      {
                          pdfContentByte.BeginText();
                          pdfContentByte.SetFontAndSize(baseFont, 9);
                          pdfContentByte.ShowTextAligned(PdfContentByte.ALIGN_CENTER,
                              string.Format("{0} de {1}", currentPage++, totalPages), 520, 5, 0);
                          pdfContentByte.EndText();
                      }
                  }
              }
          }
          finally
          {
              outputStream.Flush();
              if (newDocument != null)
                  newDocument.Close();
              outputStream.Close();
          }
      }
  
      public PdfMerge()
      {
          documents = new List<PdfReader>();
      }
  }

  Usage:

  csharp:

  string basePath = "c:\\pdf";
  
  PdfMerge demo = new PdfMerge();
  
  demo.AddDocument(Path.Combine(basePath, "static-dynamic-typing-meijer.pdf"));
  demo.AddDocument(Path.Combine(basePath, "composable-memory-transactions.pdf"));
  
  demo.Merge("mergedPapers.pdf");
  
  Console.WriteLine("Archivo generado en: {0}", Path.GetFullPath("mergedPapers.pdf"));

  If you want the source code, you can download the Visual Studio 2005 solution.

  Green Lite WordPress theme modified

  In this blog I’m using a custom version of the nice Green Lite theme, since it is a GPL theme, I’m releasing the modified version for everyone who wants it.

  I’ve made slight modifications on CSS and HTML structure (I’m not a web designer) and translated most of the italian words that are present in many files — because of the new color scheme in my version, it seems that Green Lite is no longer a suitable name
