I think this is an easy question, but having completed the tutorial, I don't yet feel up to tackling it.
I have an ASCII raster layer that I read with the Gdal plugin. I would like to prevent certain cells from being drawn (for example, only show cells with a value greater than 0). I had a look at the <Filter> rule, but couldn't tell what the variable same should be (gdal info calls it "Band 1", but that doesn't work), or if <Filter> is even meant to be used with raster layers. I also didn't see any way to do this with a RasterSymbolizer directly - is there an undocumented technique? Could someone give me a clue? Thanks, njw
