Field Detail

USE_MULTITHREADING

public static final DefaultParameterDescriptor<Boolean> USE_MULTITHREADING

This GeneralParameterValue can be provided to the GridCoverageReaders through the GridCoverageReader.read(GeneralParameterValue[]) method in order to specify to use multithreading when leveraging on a JAI ImageRead operation. This will be achieved with the use of the ImageReadMT operation of the ImageIO-Ext.

Constructor Detail

JP2KFormat

public JP2KFormat()

Creates an instance and sets the metadata.

Method Detail

setInfo

protected void setInfo()

Sets the metadata information.

getReader

public AbstractGridCoverage2DReader getReader(Object source,
                                              Hints hints)

Description copied from class: AbstractGridFormat

Gets a GridCoverageReader for this format able to create coverages out of the source object using the provided hints.

In case this Format cannot reader the provided source object null is returned.

Specified by:

getReader in class AbstractGridFormat

Parameters:

source - The source object to parse. *

hints - The Hints to use when trying to instantiate this reader.

Returns:

A reader for this Format or null.

getReader

public AbstractGridCoverage2DReader getReader(Object source)

Description copied from class: AbstractGridFormat

Gets a GridCoverageReader for this format able to create coverages out of the source object.

In case this Format cannot reader the provided source object null is returned.

Specified by:

getReader in class AbstractGridFormat

Parameters:

source - The source object to parse.

Returns:

A reader for this Format or null.

getWriter

public GridCoverageWriter getWriter(Object destination)

Description copied from class: AbstractGridFormat

Retrieves a GridCoverageWriter suitable for writing to the provided destination with this format.

In case no writers are available null is returned.

Specified by:

getWriter in class AbstractGridFormat

Parameters:

destination - The destinatin where to write.

Returns:

A GridCoverageWriter suitable for writing to the provided destination with this format.

Actually, the plugin does not support write capabilities. The method throws an .

getDefaultImageIOWriteParameters

public GeoToolsWriteParams getDefaultImageIOWriteParameters()

Description copied from class: AbstractGridFormat

Returns an instance of ImageWriteParam that can be used to control a subsequent GridCoverageWriter.write(org.geotools.api.coverage.grid.GridCoverage, org.geotools.api.parameter.GeneralParameterValue[]);

Be careful with using the ImageWriteParam since their usage is still experimental.

Specified by:

getDefaultImageIOWriteParameters in class AbstractGridFormat

Returns:

an instance of ImageWriteParam.

public GridCoverageWriter getWriter(Object destination,
                                    Hints hints)

Description copied from class: AbstractGridFormat

Call the accepts() method before asking for a writer to determine if the current object is supported.

Specified by:

getWriter in class AbstractGridFormat

Parameters:

destination - the destination object to write a WorldImage to

hints - Hints to control the internal machinery.

Returns:

a new WorldImageWriter for the destination
