Field Details

baseImage

protected BufferedImage baseImage

Constructor Details

JMapPane

public JMapPane()

Creates a new map pane.

JMapPane

public JMapPane(MapContent content)

Creates a new map pane.

Parameters:

content - the map content containing the layers to display (may be null)

JMapPane

public JMapPane(MapContent content,
 RenderingExecutor executor,
 GTRenderer renderer)

Creates a new map pane. Any or all arguments may be null

Parameters:

content - the map content containing the layers to display

executor - the rendering executor to manage drawing

renderer - the renderer to use for drawing layers

Method Details

setMapContent

public void setMapContent(MapContent content)

Sets the MapContent instance containing the layers to display.

Specified by:

setMapContent in interface MapPane

Overrides:

setMapContent in class AbstractMapPane

Parameters:

content - the map content

getRenderer

public GTRenderer getRenderer()

Gets the renderer, creating a default one if required.

Returns:

the renderer

setRenderer

public void setRenderer(GTRenderer renderer)

Sets the renderer to be used by this map pane.

Parameters:

renderer - the renderer to use

getBaseImage

public RenderedImage getBaseImage()

Retrieve the map pane's current base image.

The map pane caches the most recent rendering of map layers as an image to avoid time-consuming rendering requests whenever possible. The base image will be re-drawn whenever there is a change to map layer data, style or visibility; and it will be replaced by a new image when the pane is resized.

This method returns a live reference to the current base image. Use with caution.

Returns:

a live reference to the current base image

paintComponent

protected void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

drawLayers

protected void drawLayers(boolean createNewImage)

Description copied from class: AbstractMapPane

Draws layers into one or more images which will then be displayed by the map pane.

Specified by:

drawLayers in class AbstractMapPane
