Field Summary

protected AlphaComposite	_currentComp The alpha composite used to render our current image.
protected Mirage[]	_images The images between which we are blending.
protected int	_level Our current blend level and image index all wrapped into one.
protected AlphaComposite	_nextComp The alpha composite used to render our "next" image.
protected TimeFunction	_tfunc The time function we're using to time our blends.

Constructor Summary

BlendAnimation(int x, int y, Mirage[] images, int delay)
Blends from the starting image through each successive image in the specified amount of time (blending between each image takes place in delay milliseconds).

Method Summary

void	fastForward(long timeDelta) Called when the appropriate media manager has been paused for some length of time and is then unpaused.
void	paint(Graphics2D gfx) Called by the appropriate manager to request that the media render itself with the given graphics context.
void	tick(long timestamp) Called periodically by this media's manager to give it a chance to do its thing.

Constructor Detail

BlendAnimation

public BlendAnimation(int x,
                      int y,
                      Mirage[] images,
                      int delay)

Blends from the starting image through each successive image in the specified amount of time (blending between each image takes place in delay milliseconds).

Method Detail

tick

public void tick(long timestamp)

Description copied from class: AbstractMedia

Called periodically by this media's manager to give it a chance to do its thing.

Specified by:

tick in class AbstractMedia

Parameters:

timestamp - a time stamp associated with this tick. Note: this is not obtained from a call to System.currentTimeMillis() and cannot be compared to timestamps obtained there from.

fastForward

public void fastForward(long timeDelta)

Description copied from class: AbstractMedia

Called when the appropriate media manager has been paused for some length of time and is then unpaused. Media should adjust any time stamps that are maintained internally forward by the delta so that time maintains the illusion of flowing smoothly forward.

Overrides:

fastForward in class AbstractMedia

paint

public void paint(Graphics2D gfx)

Description copied from class: AbstractMedia

Called by the appropriate manager to request that the media render itself with the given graphics context. The media may wish to inspect the clipping region that has been set on the graphics context to render itself more efficiently. This method will only be called after it has been established that this media's bounds intersect the clipping region.

Specified by:

paint in class AbstractMedia
