Both X and Y are set to 0, in every GridCoverage2D deserialized. I think that maybe some READ_GRIDCOVERAGE2D parameters are needed (?) Original: java.awt.Rectangle[x=209,y=333,width=334,height=148] After serialization / deserialization: java.awt.Rectangle[x=0,y=0,width=334,height=148]
Serialization: ByteArrayOutputStream baos = new ByteArrayOutputStream(); GeoTiffWriter writer = new GeoTiffWriter(baos, null); GeoTiffWriteParams wp = new GeoTiffWriteParams(); wp.setSourceRegion(grid.getGridGeometry().getGridRange2D().getBounds()); final ParameterValueGroup params = new GeoTiffFormat().getWriteParameters(); params.parameter(AbstractGridFormat.GEOTOOLS_WRITE_PARAMS.getName().toString()).setValue(wp); writer.write(grid, params.values().toArray(new GeneralParameterValue[1])); writer.dispose(); byte[] bytes = baos.toByteArray(); Deserialization: ByteArrayInputStream bais = new ByteArrayInputStream(bytes); GeoTiffReader reader = null; Hints hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE); reader = new GeoTiffReader(bais, hints); GridCoverage2D grid = reader.read(null); bais.close(); return grid; Il giorno gio 7 gen 2021 alle ore 15:06 Ian Turton <ijtur...@gmail.com> ha scritto: > > How different are we talking about here?
