# Interface IIOReadWarningListener

All Superinterfaces:
  `EventListener`

    public interface IIOReadWarningListener
    extends EventListener

An interface used by `ImageReader` 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 `IIOReadWarningListener` as it is registered with an `ImageReader`. It is up to the `ImageReader` to provide localized messages.

  `ImageReader.addIIOReadWarningListener(javax.imageio.event.IIOReadWarningListener)`, `ImageReader.removeIIOReadWarningListener(javax.imageio.event.IIOReadWarningListener)`
