public interface MultiResolutionImageThis interface is designed to be an optional additional API supported by some implementations of
Imageto 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
Imageobject in order to choose the best representation to use for each rendering operation.
MultiResolutionImageinterface should be implemented by any subclass of
java.awt.Imagewhose instances are intended to provide image resolution variants according to the given image width and height. For convenience, toolkit images obtained from
Toolkit.getImage(URL url)will implement this interface on platforms that support naming conventions for resolution variants of stored image media and the
BaseMultiResolutionImageclasses are provided to facilitate easy construction of custom multi-resolution images from a list of related images.
Image getResolutionVariant(double destImageWidth, double destImageHeight)Gets a specific image that is the best variant to represent this logical image at the indicated size.
destImageWidth- the width of the destination image, in pixels.
destImageHeight- the height of the destination image, in pixels.
- image resolution variant.
destImageHeightis less than or equal to zero, infinity, or NaN.
