Method Detail

paint

public void paint(java.awt.Graphics2D graphics,
                  java.awt.Rectangle paintArea,
                  com.vividsolutions.jts.geom.Envelope mapArea)

Description copied from interface: GTRenderer

Renders features based on the map layers and their styles as specified in the map context using setContext.

This version of the method assumes that the area of the visible part of the map and the size of the output area are known. The transform between the two is calculated internally.

Specified by:

paint in interface GTRenderer

Parameters:

graphics - The graphics object to draw to.

paintArea - The size of the output area in output units (eg: pixels).

addRenderListener

public void addRenderListener(RenderListener listener)

adds a listener that responds to error events of feature rendered events.

Specified by:

addRenderListener in interface GTRenderer

Parameters:

listener - the listener to add.

See Also:

RenderListener

removeRenderListener

public void removeRenderListener(RenderListener listener)

Removes a render listener.

Specified by:

removeRenderListener in interface GTRenderer

Parameters:

listener - the listener to remove.

See Also:

RenderListener

setScaleDenominator

protected void setScaleDenominator(double scaleDenominator)

Setter for property scaleDenominator.

Parameters:

scaleDenominator - New value of property scaleDenominator.

stopRendering

public void stopRendering()

If you call this method from another thread than the one that called paint or render the rendering will be forcefully stopped before termination

Specified by:

stopRendering in interface GTRenderer

isCaching

public boolean isCaching()

DOCUMENT ME!

Returns:

Returns the caching.

setCaching

public void setCaching(boolean caching)

DOCUMENT ME!

Parameters:

caching - The caching to set.

getContext

public MapContext getContext()

Specified by:

getContext in interface GTRenderer

isConcatTransforms

public boolean isConcatTransforms()

setConcatTransforms

public void setConcatTransforms(boolean concatTransforms)

useIndex

public IndexInfo useIndex(ShapefileDataStore ds)
                   throws java.io.IOException,
                          StoreException

Throws:

java.io.IOException

StoreException

paint

public void paint(java.awt.Graphics2D graphics,
                  java.awt.Rectangle paintArea,
                  java.awt.geom.AffineTransform worldToScreen)

Description copied from interface: GTRenderer

Renders features based on the map layers and their styles as specified in the map context using setContext.

This version of the method assumes that the size of the output area and the transformation from coordinates to pixels are known. The latter determines the map scale. The viewport (the visible part of the map) will be calculated internally.

Specified by:

paint in interface GTRenderer

Parameters:

graphics - The graphics object to draw to.

paintArea - The size of the output area in output units (eg: pixels).

worldToScreen - A transform which converts World coordinates to Screen coordinates.

paint

public void paint(java.awt.Graphics2D graphics,
                  java.awt.Rectangle paintArea,
                  com.vividsolutions.jts.geom.Envelope envelope,
                  java.awt.geom.AffineTransform transform)

Description copied from interface: GTRenderer

Renders features based on the map layers and their styles as specified in the map context using setContext.

This version of the method assumes that paint area, enelope and worldToScreen transform are already computed and in sync. Use this method to avoid recomputation. Note however that no check is performed that they are really synchronized!

Specified by:

paint in interface GTRenderer

Parameters:

graphics - The graphics object to draw to.

paintArea - The size of the output area in output units (eg: pixels).

transform - A transform which converts World coordinates to Screen coordinates.
