- All Known Implementing Classes:
AbstractMultiResolutionImage,BaseMultiResolutionImage
public interface MultiResolutionImage
This interface is designed to be an optional additional API supported by
some implementations of
Image to allow them to provide
alternate images for various rendering resolutions. The various
Graphics.drawImage(...) variant methods will consult the methods
of this interface if it is implemented on the argument Image object
in order to choose the best representation to use for each rendering operation.
The MultiResolutionImage interface should be implemented by any
subclass of java.awt.Image whose instances are intended to provide
image resolution variants according to the given image width and height.
For convenience, toolkit images obtained from
Toolkit.getImage(String name) and Toolkit.getImage(URL url)
will implement this interface on platforms that support naming conventions
for resolution variants of stored image media and the
AbstractMultiResolutionImage and BaseMultiResolutionImage
classes are provided to facilitate easy construction of custom multi-resolution
images from a list of related images.
