Raster RGB composition #96

Open am2222 opened 7 years ago

am2222 commented 7 years ago

Hi, I have a question about raster composition, well I know for example in GDAL band paramete if I enter -1 all bands will be used. But how can I create an RGB composition for example 1,3,4 bands composition. One way is to read every band separate and use rastercomposition but I think it is not right way. I could not find any methods in rasterSymbolizer to composite raster bands. Is it even possible? thanks
