Ciao Mike,
glad to see that you playing with the RasterSymbolizer.
I will give you a quick answer but I would also like to ask you if you
could ping me back when you have something that I could add to since
there ar e a few extension to the SLD spec that I would like to document.
Anyway, see below..

Hi there. I'm working on a document detailing new support for
RasterSymbolizer in 1.7.0. I'm going off of the official OGC spec, but
I'm curious how much of the spec has been implemented. Specifically:
* <Opacity> (I've verified this works)
implemented
* <ColorMap> (tested for single channel sources only)
It does work for single channel sources or you have to select a single
source yourself. It is not legal to apply a ColorMap to a multiband
raster without selecting a band. I ave added a few extensions to this
element.
* <ChannelSelection>
implemented
* <ContrastEnhancement> (incl Normalize, Histogram, and GammaValue)
implemented with some extensions as well
* <ShadedRelief>
NOT implemented
* <OverlapBehavior>
NOT implemented
* <ImageOutline> (incl Line and Polygon Symbolizer)
NOT implemented (it would be trivial)
Simone.
I've tried making guess on how to develop SLD based on the OGC spec [1]
and the Geotools page [2], but I figure I'd ask here before I assume
that my problems are user error!
