Hi all,
Does GeoTiffReader support FileInputStream or other stream types as its data
source? When I try to call the read() method of GeoTiffReader, which was
created with a FileInputStream, an exception raised.
……
GridCoverageReader _reader = *new* GeoTiffReader(_fileStream);
//Imaging Exception raised here!
GridCoverage2D _grid = (GridCoverage2D) _reader.read(*null*);
……
Below are trace information:
javax.media.jai.util.ImagingException: All factories fail for the operation
