Raster is based on a Tk frame widget with our own code for fast display of images. You can draw coloured dots on a Raster, or generic Drawers. Raster widgets are double buffered - the pixels you draw are not actually put on the screen until drawSelf is called. In addition, Rasters handle mouse clicks.</P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN20109"></A><H2>Protocols adopted by Raster</H2><P>
