# Package javax.imageio.event

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.
