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.

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
