Class CompositedMultiFrameImage

java.lang.Object
  com.threerings.cast.CompositedMultiFrameImage

All Implemented Interfaces:

TrimmedMultiFrameImage, MultiFrameImage

Direct Known Subclasses:

CompositedMaskedImage, CompositedShadowImage

public class CompositedMultiFrameImage
extends Object
implements TrimmedMultiFrameImage

Used to composite the action frames for a particular orientation of a CompositedActionFrames.

Nested Class Summary

protected class	CompositedMultiFrameImage.CompositedVolatileMirage Used to create our mirage using the source action frame images.
protected class	CompositedMultiFrameImage.SubmirageForwarder A CompositedMirage that forwards all of its Mirage calls to a delegate Mirage.

Field Summary

protected String	_action The action we're compositing.
protected CompositedMirage[]	_images Our composited action frame images.
protected ImageManager	_imgr The image manager from whom we load our images.
protected int	_orient The orientation we're compositing.
protected CompositedActionFrames.ComponentFrames[]	_sources The action frames from which we obtain our source imagery.

Constructor Summary

CompositedMultiFrameImage(ImageManager imgr, CompositedActionFrames.ComponentFrames[] sources, String action, int orient)

Method Summary

protected CompositedMirage	createCompositedMirage(int index) Creates a composited image for the specified frame.
long	getEstimatedMemoryUsage() Returns the estimated memory usage of our composited frame images.
protected Mirage	getFrame(int orient, int index)
int	getFrameCount() Returns the number of frames in this multi-frame image.
int	getHeight(int index) Returns the height of the specified frame image.
void	getTrimmedBounds(int index, Rectangle bounds) Fills in the minimum bounding rectangle for this image that contains all non-transparent pixels.
int	getWidth(int index) Returns the width of the specified frame image.
int	getXOrigin(int index)
int	getYOrigin(int index)
boolean	hitTest(int index, int x, int y) Returns true if the specified frame contains a non-transparent pixel at the specified coordinates.
void	paintFrame(Graphics2D g, int index, int x, int y) Renders the specified frame into the specified graphics object at the specified coordinates.
