Package javax.imageio.event

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

Interface Summary
Interface	Description
IIOReadProgressListener	An interface used by `ImageReader` implementations to notify callers of their image and thumbnail reading methods of progress.
IIOReadUpdateListener	An interface used by `ImageReader` implementations to notify callers of their image and thumbnail reading methods of pixel updates.
IIOReadWarningListener	An interface used by `ImageReader` implementations to notify callers of their image and thumbnail reading methods of warnings (non-fatal errors).
IIOWriteProgressListener	An interface used by `ImageWriter` implementations to notify callers of their image writing methods of progress.
IIOWriteWarningListener	An interface used by `ImageWriter` implementations to notify callers of their image and thumbnail reading methods of warnings (non-fatal errors).
