All Implemented Interfaces:

GridCoverageWriter

public class ImageGridCoverageWriter
extends AbstractGridCoverageWriter

This class encapsulates functionality for writing a GridCoverage as a GeoTIFF to a defined destination. Ths destination will be given as an OutputStream. The current implementation is limited to support ImageGridCoverages to be written as GeoTIFF.

Method Detail

write

public void write(GridCoverage coverage,
                  GeneralParameterValueIm[] parameters)
           throws InvalidParameterNameException,
                  InvalidParameterValueException,
                  ParameterNotFoundException,
                  IOException

Writes the specified grid coverage.

Parameters:

coverage - The grid coverage to write.

parameters - An optional set of parameters. Should be any or all of the parameters returned by "org.opengis.coverage.grid.Format#getWriteParameters".

Throws:

InvalidParameterNameException - if a parameter in parameters doesn't have a recognized name.

InvalidParameterValueException - if a parameter in parameters doesn't have a valid value.

ParameterNotFoundException - if a parameter was required for the operation but was not provided in the parameters list.

IOException - if the export failed for some other input/output reason, including IIOException if an error was thrown by the underlying image library.

dispose

public void dispose()
             throws IOException

Allows any resources held by this object to be released. The result of calling any other method subsequent to a call to this method is undefined. It is important for applications to call this method when they know they will no longer be using this GridCoverageWriter. Otherwise, the writer may continue to hold on to resources indefinitely.

Throws:

IOException - if an error occured while disposing resources (for example while flushing data and closing a file).
