The RasterSymbolizer does not handle himself the opacity for the output coverage but it leaves that to the GridCoveageRenderer in order to prevent the creation of an intermediate image. I am realizing that it would probably be better to control this behaviour throuh a Hint so that we can use the RasterSymbolizer more in a standalone way. However, from your words it seems that your problem is related to applying a colormap with transparency not to the transparency of the whole image.

I can provide an ftp address where you can also put some test data. Is that feasible?
