A package of the Java Image I/O API dealing with synchronous notification of events during the reading and writing of images.

The IIOReadProgressListener interface allows for notification of the percentage of an image that has been read successfully.

The IIOReadUpdateListener interface allows for notification of the portions of an image that have been read. This is useful, for example, for implementing dynamic display of an image as it is loaded.

The IIOReadWarningListener interface allows for notification of non-fatal errors during reading.

The IIOWriteWarningListener and IIOWriteProgressListener interfaces perform analogous functions for writers. @since 1.4
