Field Summary

static boolean

interactive Deprecated. This flag should not be there.

Method Summary

boolean	isInteractive() Getter for property interactive.
com.vividsolutions.jts.geom.Coordinate	pixelToWorld(int x, int y, com.vividsolutions.jts.geom.Envelope map)
void	render(FeatureCollection fc, com.vividsolutions.jts.geom.Envelope viewport, Style style) Renders the provided features using the specified style.
void	setInteractive(boolean interactive) Setter for property interactive.
void	setOutput(java.awt.Graphics g, java.awt.Rectangle r) sets the output graphics for the renderer and the size of the graphic.

Field Detail

interactive

public static final boolean interactive

Deprecated. This flag should not be there.

Flag which determines if the renderer is interactive or not. An interactive renderer will return rather than waiting for time consuming operations to complete (e.g. Image Loading). A non-interactive renderer (e.g. a SVG or PDF renderer) will block for these operations.

Method Detail

render

public void render(FeatureCollection fc,
                   com.vividsolutions.jts.geom.Envelope viewport,
                   Style style)

Renders the provided features using the specified style. The features should fill the viewport but may well extend beyond it. Features should be cropped (if appropriate) to the specified viewport.

Parameters:

fc - The feature collection to render

viewport - The visible extent to be rendered

style - The style definition to apply to each feature

isInteractive

public boolean isInteractive()

Getter for property interactive.

Returns:

Value of property interactive.

setInteractive

public void setInteractive(boolean interactive)

Setter for property interactive.

Parameters:

interactive - New value of property interactive.

setOutput

public void setOutput(java.awt.Graphics g,
                      java.awt.Rectangle r)

sets the output graphics for the renderer and the size of the graphic.

pixelToWorld

public com.vividsolutions.jts.geom.Coordinate pixelToWorld(int x,
                                                           int y,
                                                           com.vividsolutions.jts.geom.Envelope map)
