 public class SVGBufferedImageOp extends AbstractSVGFilterConverter {
    
All LookupOp convertion is handed to svgLookupOp
 
     private SVGLookupOp svgLookupOp;

    
All RescaleOp convertion is handed to svgRescaleOp
 
     private SVGRescaleOp svgRescaleOp;

    
All ConvolveOp convertion is handed to svgConvolveOp
 
     private SVGConvolveOp svgConvolveOp;

    
All custom BufferedImageOp convertion is handed to ' svgCustomBufferedImageOp.
 

Parameters:
generatorContext used by the converter to create Element and other needed DOM objects and to handle unknown BufferedImageOp implementations.
 
     public SVGBufferedImageOp(SVGGeneratorContext generatorContext) {
         super(generatorContext);
         this. = new SVGLookupOp(generatorContext);
         this. = new SVGRescaleOp(generatorContext);
         this. = new SVGConvolveOp(generatorContext);
         this. =
             new SVGCustomBufferedImageOp(generatorContext);
     }

    

Returns:
Set of filter Elements defining the BufferedImageOp this Converter has processed since it was created.
 
     public List getDefinitionSet(){
         List filterSet = new LinkedList(.getDefinitionSet());
         filterSet.addAll(.getDefinitionSet());
         filterSet.addAll(.getDefinitionSet());
         filterSet.addAll(.getDefinitionSet());
         return filterSet;
     }
 
     public SVGLookupOp getLookupOpConverter(){
         return ;
     }
 
         return ;
     }
 
         return ;
     }
 
        return ;
    }

    

Parameters:
op BufferedImageOp to be converted to SVG
filterRect Rectangle, in device space, that defines the area to which filtering applies. May be null, meaning that the area is undefined.
Returns:
an SVGFilterDescriptor representing the SVG filter equivalent of the input BufferedImageOp
                                     Rectangle filterRect){
        SVGFilterDescriptor filterDesc =
            .toSVG(opfilterRect);
        if(filterDesc == null){
            if(op instanceof LookupOp)
                filterDesc = .toSVG((LookupOp)opfilterRect);
            else if(op instanceof RescaleOp)
                filterDesc = .toSVG((RescaleOp)opfilterRect);
            else if(op instanceof ConvolveOp)
                filterDesc = .toSVG((ConvolveOp)opfilterRect);
        }
        return filterDesc;
    }
