Method Detail

read

public GridCoverage2D read(GeneralParameterValue[] parameters)
                    throws IllegalArgumentException,
                           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:

parameters - Optional parameters matching Format.getReadParameters().

Returns:

a 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.

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.

IllegalArgumentException

renderTiles

protected void renderTiles(Collection<Tile> tiles,
                           Graphics2D g2d,
                           ReferencedEnvelope viewportExtent,
                           AffineTransform worldToImageTransform)

renderTile

protected void renderTile(Tile tile,
                          Graphics2D g2d,
                          double[] points)

getTileImage

protected BufferedImage getTileImage(Tile tile)

getCoordinateReferenceSystem

public CoordinateReferenceSystem getCoordinateReferenceSystem()

Description copied from class: AbstractGridCoverage2DReader

Retrieves the GeneralEnvelope for this AbstractGridCoverage2DReader.
