protected BufferedImage	_image
protected float	_percentageOfDataBuffer

Constructor Summary

BufferedMirage(BufferedImage image)

BufferedMirage(BufferedImage image, float percentageOfDataBuffer)

Method Summary

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.

Constructor Detail

BufferedMirage

public BufferedMirage(BufferedImage image)

BufferedMirage

public BufferedMirage(BufferedImage image,
                      float percentageOfDataBuffer)

Parameters:

percentageOfDataBuffer - - the percentage of image's data buffer used by image for use in getEstimatedMemory. ie if this image is a subimage of another image, and they share a data buffer, this is the percentage of the size of this image compared to the source.
