Examples of javax.imageio.event.IIOReadWarningListener

javax.imageio.event.IIOReadWarningListener
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 javax.imageio.ImageReader#addIIOReadWarningListener @see javax.imageio.ImageReader#removeIIOReadWarningListener
