Method Detail

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

project

public ProjCoordinate project(double lplam,
                              double lpphi,
                              ProjCoordinate out)

Description copied from class: Projection

Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lplam - the geographic x ordinate (in radians)

lpphi - the geographic y ordinatee (in radians)

out - the projected coordinate (in coordinate system units)

Returns:

the target coordinate

project_s

public void project_s(double lplam,
                      double lpphi,
                      ProjCoordinate out)

project_e

public void project_e(double lplam,
                      double lpphi,
                      ProjCoordinate out)

projectInverse

public ProjCoordinate projectInverse(double xyx,
                                     double xyy,
                                     ProjCoordinate out)

Description copied from class: Projection

Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.

Overrides:

projectInverse in class Projection

Parameters:

xyx - the projected x ordinate (in coordinate system units)

xyy - the projected y ordinate (in coordinate system units)

out - the inverse-projected geographic coordinate (in radians)

Returns:

the target coordinate

projectInverse_s

public void projectInverse_s(double xyx,
                             double xyy,
                             ProjCoordinate out)

projectInverse_e

public void projectInverse_e(double xyx,
                             double xyy,
                             ProjCoordinate out)

isEqualArea

public boolean isEqualArea()

Returns true if this projection is equal area

Overrides:

isEqualArea in class Projection

Returns:

true if this projection is equal-area

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Tests whether this projection has an inverse. If this method returns true then the Projection.inverseProject(ProjCoordinate, ProjCoordinate) and Projection.inverseProjectRadians(ProjCoordinate, ProjCoordinate) methods will return meaningful results.

Overrides:

hasInverse in class Projection

Returns:

true if this projection has an inverse

toString

public String toString()

Overrides:

toString in class Projection
