Lite means that: <ul> <li>The code is relatively simple to understand, so it can be used as a simple example of an SLD compliant rendering code</li> <li>Uses as few memory as possible</li> </ul> Use this class if you need a stateless renderer that provides low memory footprint and decent rendering performance on the first call but don't need good optimal performance on subsequent calls on the same data. Notice: for the time being, this class doesn't support GridCoverage stylers, that will be rendered using the non geophisics version of the GridCoverage, if available, with the geophisics one, otherwise.<P><P><DL><DT><B>Author:</B></DT> <DD>James Macgill, Andrea Aime</DD><DT><B>Module:</B></DT><DD><CODE><B>module/render</B></CODE> (<A
