                              throws IOException

Throws:

IOException

Method Detail

getFormat

public Format getFormat()

Description copied from interface: GridCoverageReader

Returns the format handled by this GridCoverageReader.

Specified by:

getFormat in interface GridCoverageReader

See Also:

GridCoverageReader.getFormat()

getInfo

public ServiceInfo getInfo()

Description copied from class: AbstractGridCoverage2DReader

Information about this source.

Subclasses should provide additional format specific information.

Specified by:

getInfo in interface GridCoverage2DReader

Overrides:

getInfo in class AbstractGridCoverage2DReader

Returns:

ServiceInfo describing getSource().

read

public GridCoverage2D read(GeneralParameterValue[] params)
                    throws IOException

Description copied from class: AbstractGridCoverage2DReader

Read the current grid coverage from the stream.

Example:

The method AbstractGridCoverage2DReader.hasMoreGridCoverages() should be invoked first in order to verify that a coverage is available.

Specified by:

read in interface GridCoverage2DReader

Specified by:

read in interface GridCoverageReader

Specified by:

read in class AbstractGridCoverage2DReader

Parameters:

params - Optional parameters matching Format.getReadParameters().

Returns:

A new grid coverage from the input source, or null if the requested envelope is outside the data bounds

Throws:

IOException - if a read operation failed for some other input/output reason, including FileNotFoundException if no file with the given name can be found, or IIOException if an error was thrown by the underlying image library.
