Rich Text FormatThe Rich Text Format (often abbreviated to RTF) is a document file format that has been continually developed by Microsoft since 1987 for cross-platform document interchange. Most word processors are able to read and write RTF documents. Unlike most of the word processing formats, RTF is human-readable. Sample RTF document As an example, the following RTF code: -
{\rtf Hello!\par This is some {\b bold} text.\par }
would be rendered like this when read by an appropriate word processor: Hello!
This is some bold text. A backslash (\) starts an RTF control code. The \par control code indicates a new line, and \b switches to a bold typeface. Braces ({ and }) define a group; the example uses a group to limit the scope of the \b control code. Everything else will be treated as clear text, or the text to be formatted. A valid RTF document is a group starting with the \rtf control code. Background and supported character sets The syntax of RTF documents is similar to that of TeX. RTF documents can be written using any of the 7- or 8-bit character sets. The most common of these include ASCII, Windows-1252, ISO 8859-1, Code page 437, and MacRoman. Common implementations The RTF format is the default rich text format for Mac OS X's default editor TextEdit. The WordPad editor at one point created RTF files by default. Though it still can view and edit RTF files, it now uses the Microsoft Word file format by default. The open-source editor AbiWord, which is common on Unix-like platforms that implement the X Window System and GTK, can also edit RTF files. These different programs do not however create files that are completely compatible with each other. See also External links RTF
