Constructor Detail

GeoImageDisplay

public GeoImageDisplay(int width,
               int height)

Create the GeoImage with the specified width and height

Parameters:

width - image width

height - image height

Method Detail

addLayer

public void addLayer(GeoLayer layer)

Add a layer to the geographic display

Specified by:

addLayer in interface GeoDisplay

Parameters:

layer - a new geographic layer

getGeoBounds

public GeoBounds getGeoBounds()

Get the geographic bounds

Specified by:

getGeoBounds in interface GeoDisplay

Returns:

the geographic bounds

getLayers

public java.util.List<GeoLayer> getLayers()

Get the list of layers. The list is returned in the order that the layers are drawn, so the first layers in the list will be below later ones. This method returns a defensive copy of the layers.

Specified by:

getLayers in interface GeoDisplay

Returns:

the list of layers.

getProjection

public Projection getProjection()

Get the current projection

Specified by:

getProjection in interface GeoDisplay

Returns:

the current projection

setGeoBounds

public void setGeoBounds(GeoBounds geoBounds)

Set the geographic bounds

Specified by:

setGeoBounds in interface GeoDisplay

Parameters:

geoBounds - the geographic bounds

setLayers

public void setLayers(java.util.Collection<GeoLayer> layers)

Set the geographic layers. The layers will be added to the internal list in iteration order.

Specified by:

setLayers in interface GeoDisplay

Parameters:

layers - the collection of geographic layers

setProjection

public void setProjection(Projection proj)

Set the current projection

Specified by:

setProjection in interface GeoDisplay

Parameters:

proj - the new projection

setWorldColor

public void setWorldColor(java.awt.Color color)

Set the world color. If worldColor is not null, the geographic extent of the world will be colored with the background color prior to drawing all geographic layers.

Parameters:

color - the new world color
