C#
//Create a new PDF document
PdfDocument doc = new PdfDocument();
//Add a page
PdfPage page = doc.Pages.Add();
SizeF bounds = page.GetClientSize();
//Read RTF document
StreamReader reader = new StreamReader("Essential PDF.rtf", Encoding.ASCII);
string text = reader.ReadToEnd();
reader.Close();
//Convert it to metafile
PdfMetafile imageMetafile = (PdfMetafile)PdfImage.FromRtf(text, bounds.Width, PdfImageType.Metafile);
PdfMetafileLayoutFormat format = new PdfMetafileLayoutFormat();
//Allow text to flow multiple pages without any break
format.SplitTextLines = true;
//Draws image
imageMetafile.Draw(page, 0, 0, format);
//Save the document
doc.Save("RtfText.pdf");
doc.Close(true);
//This will open the PDF file so, the result will be seen in default PDF viewer
Process.Start("RtfText.pdf");
VB.NET
