Class TransformedMirage

java.lang.Object
  com.threerings.media.image.TransformedMirage

All Implemented Interfaces:

Mirage

public class TransformedMirage
extends Object
implements Mirage

Draws a mirage combined with an arbitrary AffineTransform.

Field Summary

protected Mirage	_base The base mirage.
protected Rectangle	_bounds Our transformed bounds.
protected AffineTransform	_transform The transform we apply when painting the base mirage.

Constructor Summary

TransformedMirage(Mirage base, AffineTransform transform)
Constructor for backwards compatibility that automatically repositions the transformed mirage so its new upper-left corner is still at the origin.

TransformedMirage(Mirage base, AffineTransform transform, boolean reposition)
Constructor.

Method Summary

protected void	computeTransformedBounds() Compute the bounds of the base Mirage after it has been transformed.
long	getEstimatedMemoryUsage() Returns an estimate of the memory consumed by this mirage's image raster data.
int	getHeight() Returns the height of this mirage.
BufferedImage	getSnapshot() Returns a snapshot of this mirage as a buffered image.
int	getWidth() Returns the width of this mirage.
boolean	hitTest(int x, int y) Returns true if this mirage contains a non-transparent pixel at the specified coordinate.
void	paint(Graphics2D gfx, int x, int y) Renders this mirage at the specified position in the supplied graphics context.

TransformedMirage

public TransformedMirage(Mirage base,
                         AffineTransform transform)

Constructor for backwards compatibility that automatically repositions the transformed mirage so its new upper-left corner is still at the origin.

public void paint(Graphics2D gfx,
                  int x,
                  int y)

Description copied from interface: Mirage

Renders this mirage at the specified position in the supplied graphics context.

Specified by:

paint in interface Mirage

getWidth

public int getWidth()

Description copied from interface: Mirage

Returns the width of this mirage.

Specified by:

getWidth in interface Mirage

getHeight

public int getHeight()

Description copied from interface: Mirage

Returns the height of this mirage.

Specified by:

getHeight in interface Mirage

hitTest

public boolean hitTest(int x,
                       int y)
