## 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.

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

    - #### warningOccurred

          void warningOccurred(ImageReader source,
                             String warning)

      Reports the occurence of a non-fatal error in decoding. Decoding will continue following the call to this method. The application may choose to display a dialog, print the warning to the console, ignore the warning, or take any other action it chooses.
      Parameters:
        `source` - the `ImageReader` object calling this method.
        `warning` - a `String` containing the warning.
