org.geotools.process.RenderingProcess.invertQuery()
Given a target query and a target grid geometry returns the query to be used to read the input data of the process involved in rendering. This method will be called only if the input data is a feature collection. @param targetQuery @param gridGeometry @return The transformed query, or null if no inversion is possible/meaningful

        Map<String, Object> inputs = new HashMap<String, Object>();
        inputs.put("data", data);
        inputs.put("value", 10);
        
        RenderingProcess tx = (RenderingProcess) transformation;
        Query dummyQuery = tx.invertQuery(inputs, null, null);
        
        Map<String, Object> result = transformation.execute(inputs, null);


        assertEquals(1, result.size());
