AbstractGridCoverage2DReader reader = null;try { reader = new GeoTiffReader(new File(path1)); Coverage cov1 = reader.read(null ); double[] v1 = new double[]{2/3D}; Coverage cm1 = Operations.DEFAULT.multiply(cov1,v1); GeoTiffWriter writer = new GeoTiffWriter(new File(path3)); writer.write((GridCoverage) cm1 , null); writer.dispose();} catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace();}the geotiff image generated with this is black. any idea what i am doing wrong here.
