原因: java.lang.IllegalStateException:无法定位多边形的内点

Question

我在使用Geo Tiff向量化我的图像时遇到错误

//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");

输出

vectorization starts

我忘了加乐队了

 SimpleFeatureCollection fc = RasterToVectorProcess.process(srcCoverage, 3, cov.getEnvelope(), Collections.singletonList(0.0d), true, null);
