Constructor Detail

AzimuthalProjection

public AzimuthalProjection()

AzimuthalProjection

public AzimuthalProjection(double projectionLatitude,
                   double projectionLongitude)

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

inside

public boolean inside(double lon,
             double lat)

Description copied from class: Projection

Returns true if the given lat/long point is visible in this projection

Overrides:

inside in class Projection

setMapRadius

public void setMapRadius(double mapRadius)

Set the map radius (in degrees). 180 shows a hemisphere, 360 shows the whole globe.

getMapRadius

public double getMapRadius()
