方法详细资料

project

public ProjCoordinate project(double x,
                              double y,
                              ProjCoordinate out)

从类复制的说明: Projection

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

覆盖:

project 在类中 Projection

参数:

x - the geographic x ordinate (in radians)

y - the geographic y ordinatee (in radians)

out - the projected coordinate (in coordinate system units)

返回:

the target coordinate

projectInverse

public ProjCoordinate projectInverse(double x,
                                     double y,
                                     ProjCoordinate out)

从类复制的说明: Projection

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

覆盖:

projectInverse 在类中 Projection

参数:

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

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

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

返回:

the target coordinate

initialize

public void initialize()

从类复制的说明: 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.

覆盖:

initialize 在类中 Projection

hasInverse

public boolean hasInverse()

从类复制的说明: 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.

覆盖:

hasInverse 在类中 Projection

返回:

true if this projection has an inverse

toString

public String toString()

覆盖:

toString 在类中 Projection
