I use Swing’s RTFEditorKit in Java 6 like this: RTFEditorKit rtfParser = new RTFEditorKit(); Document document = rtfParser.createDefaultDocument(); rtfParser.read(new ByteArrayInputStream(rtfBytes), document, 0); String text = document.getText(0, document.getLength()); and thats working.
Here is a piece of code that can extract all objects (‘Package’ class objects) from an RTF stream: public static void ExtractPackageObjects(string filePath) { using (StreamReader sr = new StreamReader(filePath)) { RtfReader reader = new RtfReader(sr); IEnumerator<RtfObject> enumerator = reader.Read().GetEnumerator(); while(enumerator.MoveNext()) { if (enumerator.Current.Text == “object”) { if (RtfReader.MoveToNextControlWord(enumerator, “objclass”)) { string className = RtfReader.GetNextText(enumerator); … Read more
I’ve been working on a library called Pyth, which can do this: http://pypi.python.org/pypi/pyth/ Converting an RTF file to plaintext looks something like this: from pyth.plugins.rtf15.reader import Rtf15Reader from pyth.plugins.plaintext.writer import PlaintextWriter doc = Rtf15Reader.read(open(‘sample.rtf’)) print PlaintextWriter.write(doc).getvalue() Pyth can also generate RTF files, read and write XHTML, generate documents from Python markup a la Nevow’s stan, … Read more
Doesn’t RichTextBox always have the same header/footer? You could just read the content based on off-set location, and continue using it to parse. (I think? please correct me if I’m wrong) There are libraries available, but I’ve never had good luck with them personally (though always just found another method before fully exhausting the possibilities). … Read more
Provided that all the characters that you’re catering for exist in the Basic Multilingual Plane (it’s unlikely that you’ll need anything more), then a simple UTF-16 encoding should suffice. Wikipedia: All possible code points from U+0000 through U+10FFFF, except for the surrogate code points U+D800–U+DFFF (which are not characters), are uniquely mapped by UTF-16 regardless … Read more
Actually there is a simple and free solution: use your browser, ok this is the trick I used: var webBrowser = new WebBrowser(); webBrowser.CreateControl(); // only if needed webBrowser.DocumentText = *yourhtmlstring*; while (_webBrowser.DocumentText != *yourhtmlstring*) Application.DoEvents(); webBrowser.Document.ExecCommand(“SelectAll”, false, null); webBrowser.Document.ExecCommand(“Copy”, false, null); *yourRichTextControl*.Paste(); This could be slower than other methods but at least it’s free … Read more

The equivalent of the following HTML: <a href=”https://www.google.com”>Google</a> for an RTF file is: {\field{\*\fldinst HYPERLINK “http://www.google.com/”}{\fldrslt Google}} which results in a link: Google but without additional style information, will appear unformatted: Google
I would check out this tool on CodeProject RTFConverter. This guy gives a great breakdown of how the program works along with details of the conversion. Writing Your Own RTF Converter
The most straightforward way would be to modify the RTF code to insert the picture yourself. In RTF, a picture is defined like this: ‘{‘ \pict (brdr? & shading? & picttype & pictsize & metafileinfo?) data ‘}’ A question mark indicates the control word is optional. “data” is simply the content of the file in … Read more
