Method Summary

Modifier and Type	Method and Description
public boolean	canUseCacheFile() Overrides javax.imageio.spi.ImageOutputStreamSpi.canUseCacheFile. Returns `true` if the `ImageOutputStream` implementation associated with this service provider can optionally make use of a cache `File` for improved performance and/or memory footrprint.
public ImageOutputStream	createOutputStreamInstance(Object output, boolean useCache, File cacheDir) Implements abstract javax.imageio.spi.ImageOutputStreamSpi.createOutputStreamInstance. Returns an instance of the `ImageOutputStream` implementation associated with this service provider.
public String	getDescription(Locale locale) Implements abstract javax.imageio.spi.IIOServiceProvider.getDescription. Returns a brief, human-readable description of this service provider and its associated implementation.
public boolean	needsCacheFile() Overrides javax.imageio.spi.ImageOutputStreamSpi.needsCacheFile. Returns `true` if the `ImageOutputStream` implementation associated with this service provider requires the use of a cache `File`.
