How To- Convert Multipage Tiff file into PDF in ASP.Net using C#

Here, I am explaining how to convert a multipage tiff file into PDF file in C#. Sometimes we have a requirement to convert the multipage tiff file into PDF.I am using the iTextSharp (third party dll) for conversion of multipage tiff file into PDF file.

In my previous posts, I explained Send mail in ASP.Net, Convert DataTable into List, Constructor Chainning in C#, Convert a Generic List to a Datatable, Get Property Names using Reflection in C#, Hard drive information using C#, Create Directory/Folder using C#, Check Internet Connection using C#, SQL Server Database BackUp using C# and some other articles related to C#, ASP.Net,  jQuery, Java Script and SQL Server.

Before starting the sample code, First of all download the iTextSharp and add the reference of following dll into your application.

?

1	itextsharp.dll

Now add the following namespaces in your code page.

?

1 2 3 4

using System.Drawing; using System.Drawing.Imaging; using iTextSharp.text; using iTextSharp.text.pdf;

After adding above namespaces, write the following function.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

public void ConvertMultipageTifftoPdf() {   // Create the document with a certain size and certain margins    Document document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 0, 0, 0, 0);   // creation of output pdf file   PdfWriter writer = PdfWriter.GetInstance(document, new System.IO.FileStream(Server.MapPath("~/PDF/Output.pdf"), System.IO.FileMode.Create));   // load the tiff image and count the total number of pages    Bitmap bm = new System.Drawing.Bitmap(Server.MapPath("~/Image/multipage_tiff_example.tif"));   int total = bm.GetFrameCount(FrameDimension.Page);   document.Open();   PdfContentByte cb = writer.DirectContent;   for (int k = 0; k < total; ++k)   {     bm.SelectActiveFrame(FrameDimension.Page, k);     iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bm, ImageFormat.Bmp);     // scale the image to fit in the page     img.ScalePercent(72f / img.DpiX * 100);     img.SetAbsolutePosition(0, 0);     cb.AddImage(img);     document.NewPage();   }   document.Close();           }
