package javax.imageio.event;
import java.util.EventListener;
import javax.imageio.ImageWriter;
An interface used by ImageWriter implementations to notify callers of their image and thumbnail reading methods of warnings (non-fatal errors). Fatal errors cause the relevant read method to throw an IIOException. Localization is handled by associating a Locale with each IIOWriteWarningListener as it is registered with an ImageWriter. It is up to the ImageWriter to provide localized messages.

Reports the occurrence of a non-fatal error in encoding. Encoding

generating the warning.
- warning – a
String containing the warning.
