Hi Everyone, I'm new to the list and am not sure if this has been properly answered already. The old posts that I have found all seem slightly different regarding this topic, so I thought it would be safest to ask again.
Is it possible to set a CLASS to be transparent? The use-case being that I would like to put a raster layer underneath a layer of US states, and selectively expose the rasters by making specific states transparent. I suppose that I could write a CLASS expression for each state, and simply omit an entry for each state that I want exposed, but I wonder if there is a better way? Thanks in advance for any suggestions you can give. Roger --
