isBackBufferSupported

public boolean isBackBufferSupported()

Description copied from interface: DrawingSurface

Returns true if this surface offers a backing buffer. Backing buffers can improve performance since they only need to be updated when the map view frame changes, the legend changes, or the vector data changes.

If this method returns true, the implementation must also support the methods setDrawingToBackBuffer() and copyBackBuffer()

Specified by:

isBackBufferSupported in interface DrawingSurface

Overrides:

isBackBufferSupported in class AbstractDrawingSurface

isDrawingToBackBuffer

public boolean isDrawingToBackBuffer()

Description copied from interface: DrawingSurface

Returns true if the surface is currently drawing to a backing buffer. Returns false if it is not (or if it doesn't have one).

Specified by:

isDrawingToBackBuffer in interface DrawingSurface

Overrides:

isDrawingToBackBuffer in class AbstractDrawingSurface

Returns:

true if surface is currently drawing to a backing buffer.

setDrawingToBackBuffer

public void setDrawingToBackBuffer(boolean isit)

Description copied from interface: DrawingSurface

Sets whether the surface should draw to the backing buffer (true) or to the onscreen or "front" buffer (false). Throws UnsupportedOperationException if isBackBufferSupported() returns false.

Specified by:

setDrawingToBackBuffer in interface DrawingSurface

Overrides:

setDrawingToBackBuffer in class AbstractDrawingSurface

Parameters:

isit - true if surface should start drawing to the backing buffer

copyBackBuffer

public void copyBackBuffer()

Description copied from interface: DrawingSurface

Copies the back buffer to the onscreen or "front" buffer. Throws UnsupportedOperationException if isBackBufferSupported() returns false.

Specified by:

copyBackBuffer in interface DrawingSurface

Overrides:

copyBackBuffer in class AbstractDrawingSurface

pushName

public void pushName(int i)

popName

public void popName()

drawWheelMenuCenter

public void drawWheelMenuCenter(WheelMenu menu)

drawWheelMenu

public void drawWheelMenu(WheelMenu menu)

rotationFor

public ImageRotation rotationFor(java.awt.Image image,
                        float theta)

startMonochromeDrawing

public void startMonochromeDrawing()

Switches surface into a monochrome drawing mode.

stopMonochromeDrawing

public void stopMonochromeDrawing()

Switches surface out of a monochrome drawing mode.
