Constructor Summary

Vis5DCoordinateSystem(int Projection, double[] projargs, double Nr, double Nc)

Method Summary

boolean	equals(Object cs) Indicates whether or not this instance is equal to an object (note must test for cs == null).
double[][]	fromReference(double[][] latlon) Convert RealTuple values from Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array.
double	getColumns() Get the number of Columns
Rectangle2D	getDefaultMapArea() Get the bounds for this image
int	getProjection() Get the Projection type
double[]	getProjectionParams() Get the projection args
double	getRows() Get the number of Rows
boolean	isXYOrder() Override from super class since toRef and fromRef use rowcol (yx) order instead of colrow (xy) order.
static void	main(String[] args)
double[][]	toReference(double[][] rowcol) Convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array.

Method Detail

getDefaultMapArea

public Rectangle2D getDefaultMapArea()

Get the bounds for this image

Specified by:

getDefaultMapArea in class MapProjection

Returns:

the bounding box of the MapProjection

getProjection

public int getProjection()

Get the Projection type

getRows

public double getRows()

Get the number of Rows

getColumns

public double getColumns()

Get the number of Columns

getProjectionParams

public double[] getProjectionParams()

Get the projection args

isXYOrder

public boolean isXYOrder()

Override from super class since toRef and fromRef use rowcol (yx) order instead of colrow (xy) order.

Overrides:

isXYOrder in class MapProjection

Returns:

false

toReference

public double[][] toReference(double[][] rowcol)
                       throws VisADException

Description copied from class: CoordinateSystem

Convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array.

Specified by:

toReference in class CoordinateSystem

Parameters:

rowcol - array of values assumed to be in coordinateSystem units. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of double values in reference coordinates and Units.

Throws:

VisADException - if problem with conversion.

fromReference

public double[][] fromReference(double[][] latlon)
                         throws VisADException

Description copied from class: CoordinateSystem

Convert RealTuple values from Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array.

Specified by:

fromReference in class CoordinateSystem

Parameters:

latlon - array of values assumed to be in reference Units. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of double values in CoordinateSystem Units.

Throws:

VisADException - if problem with conversion.

equals

public boolean equals(Object cs)

Description copied from class: CoordinateSystem

Indicates whether or not this instance is equal to an object (note must test for cs == null).

Specified by:

equals in class CoordinateSystem

Parameters:

cs - the object in question.

Returns:

true if and only if this instance equals cs.

main

public static void main(String[] args)
                 throws VisADException

Throws:

VisADException
