How to Convert Multipage TIFF image to PDF with C#?

Some times we need to convert the tiff image to PDF file as requirement demands. There are a few for .NET including iTextSharp, PDFsharp and PDF Clown. Here we will use iTextSharp sample that was showing how to create a PDF file from a multipage TIFF image

// creation of the document with a certain size and certain margins

iTextSharp.text.Document document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 0, 0, 0, 0);

// Creation of the different writers

iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.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

System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(Server.MapPath("~/FolderLocation/file.tif"));

int total = bmp.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page);

document.Open();

iTextSharp.text.pdf.PdfContentByte cb = writer.DirectContent;

for (int k = 0; k < total; ++k)

{

        bmp.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page, k);

        iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bm, System.Drawing.Imaging.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();
