Hi, I was able to solve this problem with adding an alpha-channel to the image using GDAL.
The command is: gdalwarp -of GTiff -srcnodata 0 -dstalpha sourceFile.sid resultFile.tif After converting the image from RGB to RGBA the black edging was transparent without adding an extra style to the layer (I am using the default_raster style instead).

We would need to add extensions to SLD to support multiband color maps (that would be "odd", since they would be value maps, not color maps, that is, each band getting a new value), and then code support for that On trunk the problem could be addressed also by writing a WPS process that changes the values of the various bands, and then using it in SLD as a rendering transformation Cheers Andrea -- Ing.
