## Interface IIOWriteWarningListener

- All Superinterfaces:
    EventListener

      public interface IIOWriteWarningListener
      extends EventListener

  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.

  See Also:
    `ImageWriter.addIIOWriteWarningListener(javax.imageio.event.IIOWriteWarningListener)`, `ImageWriter.removeIIOWriteWarningListener(javax.imageio.event.IIOWriteWarningListener)`

- - ### Method Detail

    - #### warningOccurred

          void warningOccurred(ImageWriter source,
                             int imageIndex,
                             String warning)

      Reports the occurence of a non-fatal error in encoding. Encoding 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 `ImageWriter` object calling this method.
        `imageIndex` - the index, starting with 0, of the image generating the warning.
        `warning` - a `String` containing the warning.
