TclRFB is a pure-Tcl implementation of the Remote Framebuffer (RFB) protocol that is used in the Virtual Network Computing (VNC) remote desktop application. Currently, TclRFB supports version 3.3 of the RFB protocol. Both client and server functions are supported. Multiple client and/or server instances can exist within the same interpreter. Currently supported RFB encodings are Raw, CopyRect, RRE, CoRRE, and Hextile.
TclRFB requires Tcl 8.4 or later to run. It does not rely on any given widget library. Any widget library with bindings to Tcl can be used (e.g. Tk, gnocl (gTk), or the Tcl bindings to FLTK) or none at all. The authentication component of the protocol is fully supported when either the TclDES (Data Encryption Standard and Triple-DES) or TclDESjr (Data Encryption Standard only) extension is used with TclRFB (see above).
The intent of TclRFB is to enable the creation of light-weight, scripted remote interfaces. The user interface can then be displayed through a VNC viewer, using either the standalone version (Unix, Windows, Macintosh, Palm, and other platforms), the Java-based version running in a web browser, or one based on TclRFB.
