MipMappedBufferedImageRaster

protected MipMappedBufferedImageRaster(Sector sector,
                                       BufferedImage image)

Method Detail

chooseRasterForCanvas

protected BufferedImageRaster chooseRasterForCanvas(BufferedImageRaster canvas)

computeMipmapLevel

protected int computeMipmapLevel(int sourceWidth,
                                 int sourceHeight,
                                 Sector sourceSector,

dispose

public void dispose()

Specified by:: dispose in interface Disposable
Overrides:: dispose in class BufferedImageRaster

doDrawOnCanvas

protected void doDrawOnCanvas(BufferedImageRaster canvas,
                              Sector clipSector)

Overrides:: doDrawOnCanvas in class BufferedImageRaster

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
