Examples of IIOException

ae.javax.imageio.IIOException
An exception class used for signaling run-time failure of reading and writing operations.
In addition to a message string, a reference to another Throwable (Error or Exception) is maintained. This reference, if non-null, refers to the event that caused this exception to occur. For example, an IOException while reading from a File would be stored there.
