OpImage
subclass that simply transmits its source unchanged. This may be useful when an interface requires an OpImage
but another sort of RenderedImage
(such as a BufferedImage
or TiledImage
) is available. Additionally, NullOpImage
is able to make use of JAI's tile caching mechanisms. Methods that get or set properties are implemented to forward the requests to the source image; no independent property information is stored in the NullOpImage
itself.
