There is a good portion of posts on the internet about performing Optical Character Recognition (OCR). There many free OCR engines that you can use like MODI, GOCR, Akshara Malayalam and Tesseract. I implement an OCR engine from leadtools in my application but I was able to do a quick search and find many samples on how to use Tesseract OCR engine. Here is the link: http://www.codeproject.com/Articles/696537/How-to-Use-Tessnet-Library And you can find more information about Tesseract here: https://code.google.com/p/tesseract-ocr/

Hi Narasingh Add the reference of itextsharp.dll from the Nugate packages private void button7_Click( object sender, EventArgs e) { ConvertImageToPdf( "D://lotous.jpg" , "D://lotous.pdf" ); } public static void ConvertImageToPdf( string srcFilename, string dstFilename) { iTextSharp.text.Rectangle pageSize = null ; using (var srcImage = new Bitmap(srcFilename)) { pageSize = new iTextSharp.text.Rectangle(0, 0, srcImage.Width, srcImage.Height); } using (var ms = new MemoryStream()) { var document = new iTextSharp.text.Document(pageSize, 0, 0, 0, 0); iTextSharp.text.pdf.PdfWriter.GetInstance(document, ms).SetFullCompression(); document.Open(); var image = iTextSharp.text.Image.GetInstance(srcFilename); document.Add(image); document.Close(); File.WriteAllBytes(dstFilename, ms.ToArray()); } }
