Constructor Detail

WireframeMapRenderer

public WireframeMapRenderer(java.awt.Graphics2D g,
                            NavigatableComponent nc,
                            boolean isInactiveMode)

Creates an wireframe render

Parameters:

g - the graphics context. Must not be null.

nc - the map viewport. Must not be null.

isInactiveMode - if true, the paint visitor shall render OSM objects such that they look inactive. Example: rendering of data in an inactive layer using light gray as color only.

Throws:

java.lang.IllegalArgumentException - if g is null

java.lang.IllegalArgumentException - if nc is null

Method Detail

getColors

public void getColors()

Description copied from class: AbstractMapRenderer

Reads the color definitions from preferences. This function is public, so that color names in preferences can be displayed even without calling the wireframe display before.

Overrides:

getColors in class AbstractMapRenderer

getSettings

protected void getSettings(boolean virtual)

Description copied from class: AbstractMapRenderer

Reads all the settings from preferences. Calls the AbstractMapRenderer.getColors() function.

Overrides:

getSettings in class AbstractMapRenderer

Parameters:

virtual - true if virtual nodes are used

Description copied from interface: Rendering

Renders the OSM data in data

Specified by:
