Methods

Modifier and Type	Method and Description
PTransformActivity	animateStaticViewToCenterBoundsFast(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(AffineTransform dest, 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 BufferedImage	getPaintBuffer() Get the buffer used to provide fast image based animation.

Method Detail

getPaintBuffer

protected BufferedImage getPaintBuffer()

Get the buffer used to provide fast image based animation.

Returns:

buffered image used to provide fast image based animation

animateStaticViewToCenterBoundsFast

public PTransformActivity animateStaticViewToCenterBoundsFast(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.

Parameters:

centerBounds - bounds to which the view should be centered

shouldScaleToFit - whether the camera should scale to fit the bounds so the cover as large a portion of the canvas without changing the aspect ratio

duration - milliseconds the animation should last

Returns:

the scheduled activity, null if duration was 0

animateStaticViewToTransformFast

protected PTransformActivity animateStaticViewToTransformFast(AffineTransform dest,
                                                  long duration)

This copies the behavior of the standard animateViewToTransform but clears the cache when it is done.

Parameters:

dest - the resulting transform that the view should be applying when the animation is complete

duration - length in milliseconds that the animation should last

Returns:

the scheduled PTransformActivity, null if duration was 0

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 - Paint Contex in which the painting is done
