Hi,
Can Geoserver reproject raster data on the fly and can they make a pixel color invisible like 0,0,0. As an example if I have a geotiff that is in EPSG:26915 and I want to be able to display it with all my other data that is in EPSG:4326, and I also want to not show a black border that is around the edge of the image by making 0,0,0 pixels invisible.
Thanks,

Hi John,
The answer to the first question is yes. GeoServer will reproject accordingly based on the crs you specify in the request.
The second one I am not sure about. I don't believe there is a way to directly do this in GeoServer. You might be able to use another program like gdal to pull this off. I think I remember reading something about perhaps transforming the raster and setting the pixels you want to be transparent to the "no data" value. I am sure someone more knowledgeable will have a better answer for this.
