Causée par: java.lang.IllegalStateException: ne peut pas localiser le point intérieur pour le polygone

Question

J'obtiens l'erreur lors de l'utilisation Geo Tiff pour vectorisation mon image

//vectorization 
System.out.println("vectorization starts"); 
GridCoverage2D srcCoverage = new GeoTiffReader(new File("E:/output/sometiffile.TIFF")).read(new GeneralParameterValue[]{policy, gridsize, useJaiRead}); 
SimpleFeatureCollection fc = RasterToVectorProcess.process(srcCoverage, 0, cov.getEnvelope(), Collections.singletonList(0.0d), true, null); 
System.out.println("process ends"); 
MapContext map = new DefaultMapContext(); 
map.setTitle("raster to vector conversion"); 
Style style = SLD.createPolygonStyle(Color.BLUE, Color.CYAN, 1.0f); 
map.addLayer(fc, style); 
JMapFrame.showMap(map); 
System.out.println("vectorization ends");
