Method Detail

project

public Point2D.Double project(double lplam,
                              double lpphi,
                              Point2D.Double out)

Description copied from class: Projection

The method which actually does the projection. This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lplam - Longitude in radians.

lpphi - Latitude in radians.

out - The projected point.

Returns:

The projected point, identical to parameter dst.

projectInverse

public Point2D.Double projectInverse(double xyx,
                                     double xyy,
                                     Point2D.Double out)

Description copied from class: Projection

The method which actually does the inverse projection. This should be overridden for all projections.

Overrides:

projectInverse in class Projection

initialize

public void initialize()

Description copied from class: Projection

Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.

Overrides:

initialize in class Projection

isEqualArea

public boolean isEqualArea()

Returns true if this projection is equal area

Overrides:

isEqualArea in class Projection

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Returns true if this projection has an inverse

Overrides:

hasInverse in class Projection

getEPSGCode

public int getEPSGCode()

Returns the ESPG code for this projection, or 0 if unknown.

Overrides:

getEPSGCode in class Projection

toString

public String toString()

Overrides:

toString in class ConicProjection
