SimpleRasterConfigurator problems
---------------------------------

         Key: UDIG-828
         URL: http://jira.codehaus.org/browse/UDIG-828
     Project: uDIG
        Type: Bug

  Components: style  
    Versions: UDIG 1.1.RC2    
 Environment: WMS layer from MapServer
    Reporter: Vitali Diatchkov
 Assigned to: Cory Horner 


There are several problems with raster styles:

1) RasterViewer.get(..) returns null as a Symbolizer.. Later it leads to impossibility to persist style by SLDTransformer and following errors to load style:

java.lang.RuntimeException: Internal transformation exception
	at org.geotools.styling.SLDTransformer$SLDTranslator.encode(SLDTransformer.java:669)
	at org.geotools.xml.transform.TransformerBase$XMLReaderSupport.parse(TransformerBase.java:611)

	at net.refractions.udig.style.sld.SimpleRasterConfigurator.synchronize(SimpleRasterConfigurator.java:141)

2) Opacity value in RasterViewer is not persisted during changes of active layer in "Layers" view.

3) This problem is more related to rendering: at the current moment the buffered image of WMS layer is not cleared and newly loaded image is rendered on the top of old. If the opacity value of raster style is 25% - then images are overlapped with 75% of transparency..
