I'd recommend just re-rendering the raster off-line for
performance reasons, but if data management makes that difficult
have a look at the "Classifying Rasters" section of
<a class="moz-txt-link-freetext" href="http://www.mapserver.org/input/raster.html#how-are-rasters-added-to-a-map-file">http://www.mapserver.org/input/raster.html#how-are-rasters-added-to-a-map-file</a>.
And Mapserver can only classify a single 8-bit band (grey or
paletted), even if your image is say 3 band RGB.<br>
