Hi Simone,
Thanks for your attention. I'm using GeoServer 2.4.0 and right now I'm
trying to use
Background value=0
InputTransparentColor=000000
But when I open the openlayer image preview in Geoserver, I still see the
black border around the image. One thing I noticed is that by using the
InputTransparentColor, I now have an alpha channel with correct values but
apparently the image preview is not respecting the alpha channel.
Bellow is the gdalinfo for one of the pyramids tile.
