Raheel Ahmad · Answer

Hi Mclean, You can try ByteScout PDF SDK for this purpose, it's very simple and straighforward by using this SDK. Sample code is given as under // Create new Document object Document pdfDocument = new Document(); pdfDocument.RegistrationName = "demo" ; pdfDocument.RegistrationKey = "demo" ; // Load existing document pdfDocument.Load( "sample.pdf" ); // Add new page to loaded document Page page = new Page(PaperFormat.A4); Font font = new Font(StandardFonts.Times, 24); Brush brush = new SolidBrush(); page.Canvas.DrawString( "New Page" , font, brush, 20, 20); pdfDocument.Pages.Add(page); // Save document to file pdfDocument.Save( "result.pdf" ); // Cleanup pdfDocument.Dispose(); // Open document in default PDF viewer app Process.Start( "result.pdf" ); You can find the further details under this link. https://bytescout.com/products/developer/pdfsdk/bytescoutpdf_add_text_to_existing_pdf_document.html

Your question is quite general, so I will try to provide a general useful answer. The easiest way to read and write PDF files is to use a toolkit. You can use LEADTOOLS to read and manipulate PDF files (merge, parse, copy, extract, convert to and from PDF, etc..). For example, if you want to get the text from the PDF file, the code is similar to this: using (var document = DocumentFactory.LoadFromFile(inFile, new LoadDocumentOptions())) { var page = document.Pages[0]; var pageText = page.GetText(); if (pageText != null ) { pageText.BuildText(); var text = pageText.Text; MessageBox.Show(text); } else { MessageBox.Show( "Failed!" ); } } To write PDF, you can either save it as image, or as searchable text (or image-over-text which has both).

Hi drake 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()); } }
