Constructor Detail

MipMappedBufferedImageRaster

public MipMappedBufferedImageRaster(Sector sector,
                                    java.awt.image.BufferedImage image)

Creates a mipmapped version of a BufferedImageRaster from a single BufferedImage instance.

Parameters:

sector - A sector

image - BufferedImage

MipMappedBufferedImageRaster

public MipMappedBufferedImageRaster(Sector sector,
                                    java.awt.image.BufferedImage[] images)

Creates a mipmapped version of a BufferedImageRaster from multi-resolution array od BufferedImage instances.

Parameters:

sector - A sector

images - An array of BufferedImages

Method Detail

getSizeInBytes

public long getSizeInBytes()

Description copied from interface: Cacheable

Retrieves the approximate size of this object in bytes. Implementors are encouraged to calculate the exact size for smaller objects, but use approximate values for objects that include such large components that the approximation would produce an error so small that the extra computation would be wasteful.

Specified by:

getSizeInBytes in interface Cacheable

Overrides:

getSizeInBytes in class BufferedImageRaster

Returns:

this Cacheable object's size in bytes

dispose

public void dispose()

Description copied from interface: Disposable

Disposes of any internal resources allocated by the object.

Specified by:

dispose in interface Disposable

Overrides:

dispose in class BufferedImageRaster

doDrawOnTo

protected void doDrawOnTo(BufferedImageRaster canvas)

Overrides:

doDrawOnTo in class BufferedImageRaster

chooseRasterForCanvas

protected BufferedImageRaster chooseRasterForCanvas(BufferedImageRaster canvas)

computeMipmapLevel

protected int computeMipmapLevel(int sourceWidth,
                                 int sourceHeight,
                                 Sector sourceSector,
                                 int destWidth,
                                 int destHeight,
                                 Sector destSector)
