I have been trying to update the symbology of my raster layer file but nothing is happening. I don't get any error messages from using updateLayer or ApplySymbologyFromLayer. It also printed symbology done like everything was succesful but when I open the .mxd to check, I don't see any changes in my raster. Can anyone tell me what I am doing wrong? Any help will be much appreciated
Also I have been trying to clip my raster IDW layer by the Tampa water feature class file with no luck. I know how to do it using the ArcGIS data frame properties but not with scripting...does anyone know how to script it?
