Method Summary
 PTransformActivity animateStaticViewToCenterBoundsFast(java.awt.geom.Rectangle2D centerBounds, boolean shouldScaleToFit, long duration)
          Mimics the standard animateViewToCenterBounds but uses a cached image for performance rather than re-rendering the scene at each step
protected  PTransformActivity animateStaticViewToTransformFast(java.awt.geom.AffineTransform destination, long duration)
          This copies the behavior of the standard animateViewToTransform but clears the cache when it is done
 void fullPaint(PPaintContext paintContext)
          Overrides the camera's full paint method to do the fast rendering when possible
protected  java.awt.image.BufferedImage getPaintBuffer()
          Get the buffer used to provide fast image based animation

public PCacheCamera()
Method Detail

getPaintBuffer

protected java.awt.image.BufferedImage getPaintBuffer()
Get the buffer used to provide fast image based animation


animateStaticViewToCenterBoundsFast

public PTransformActivity animateStaticViewToCenterBoundsFast(java.awt.geom.Rectangle2D centerBounds,
                                                              boolean shouldScaleToFit,
                                                              long duration)
Mimics the standard animateViewToCenterBounds but uses a cached image for performance rather than re-rendering the scene at each step


animateStaticViewToTransformFast

protected PTransformActivity animateStaticViewToTransformFast(java.awt.geom.AffineTransform destination,
                                                              long duration)
This copies the behavior of the standard animateViewToTransform but clears the cache when it is done


fullPaint

public void fullPaint(PPaintContext paintContext)
Overrides the camera's full paint method to do the fast rendering when possible

Overrides:
fullPaint in class PCamera
Parameters:
paintContext - the paint context to use for painting this node and its children
