Method Detail

read

public GridCoverage read(GeneralParameterValueIm[] parameters)
                  throws InvalidParameterNameException,
                         InvalidParameterValueException,
                         ParameterNotFoundException,
                         java.io.IOException

Read the grid coverage from the current stream position, and move to the next grid coverage.

Parameters:

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

Returns:

A new grid coverage from the input source.

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.

java.io.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.
