RasterSymbolizer (Groovy Documentation)

geoscript.style.RasterSymbolizer

```
class RasterSymbolizer
extends Symbolizer
```
A Raster Symbolizer is used to style Rasters. It is also a base class for all other Raster Symbolizers.
Most commonly you will only use the RasterSymbolizer to control opacity:
```
 def raster = new RasterSymbolizer(0.5)
 
```
But you can also control overlap and geometry name properties:
```
 def raster = new RasterSymbolizer(0.75, "AVERAGE", "the_geom")
 
```
